Pricing and obfuscation with complexity averse consumers

Competition models typically assume that consumers who cannot compare prices, buy randomly. This paper models the idea that ﬁrms may obfuscate product information to confuse consumers, but confused consumers prefer simple alternatives. We show that complexity aversion generates competition in obfuscation, in addition to prices. Markets become more transparent, which enables more consumers to understand prices and stimulates price competition. Three results are most interest- ing. Firstly, even when simple products are the most expensive in the market, ﬁrm proﬁt can be lower when confused consumers favour simple products. Secondly, proﬁt is not always lower in less obfuscated markets. Thirdly, obfuscation can only be eliminated if some consumers are always confused and policies to improve consumer sophistication can stimulate obfuscation.

Introduction
The framing of product information strongly influences consumers' choices. In particular, retailers often complicate their product information to confuse consumers and soften price competition, referred to as strategic obfuscation. 1 Whilst the incentives for firms to obfuscate have been extensively explored for many variations in the supply side of the market, surprisingly little attention has been given to how consumers respond to obfuscation. Theoretical models typically assume that some consumers buy at the lowest price, whilst others (who cannot understand prices) choose randomly. When sellers compete only in prices, this random purchase rule is justified because products are homogeneous and consumers have no preferences over sellers. However, when sellers also choose their obfuscation, the rule requires that consumers are indifferent between complex and simple alternatives, which is contradicted by evidence. Instead, buyers exhibit complexity aversion and discriminate against obfuscating sellers. Huck and Weizsäcker (1999), Mador et al. (2000), and Sonsino et al. (2002) gave initial traction to the existence of complexity aversion in experimental appraisals of expected utility theory. Participants bid lower prices for, or choose to avoid, more complicated lotteries irrespective of risk. Using survey data, Spenner and Freeman (2012) find that consumers are more likely to choose simple products, which are easier to evaluate and simplify decision-making. Homburg et al. (2014) document complexity aversion in a retail market experiment. Buyers are less likely to purchase complex promotions, which individuals associate with higher prices, lower price fairness and lower transparency. Iyengar and Kamenica (2010) show that individuals are biased towards less complex investments and De los Santos et al. (2012) find that the ease with which consumers can navigate around prices online affects choices. Huck and Wallace (2015) show that price framing influences decision-making significantly and Lesgards et al. (2015) show that individuals choose simple linear tariffs instead of more complicated but advantageous non-linear tariffs.
How does complexity aversion affect firms' obfuscation and pricing incentives? Does complexity aversion harm firms, consumers or both? When are consumer protection policies effective? Our objective in this paper is to address these important open questions. Our enquiry is motivated by two observations. Firstly, the increased regulatory concern that obfuscation induces imperfect and persistently low levels of consumer switching, which causes otherwise competitive markets to fail (Wilson and Waddams Price, 2010;CMA, 2015aCMA, , 2015b. Secondly, the growth in simplicity-orientated marketing (Siegel and Gale, 2017).
For example, some UK supermarkets have voluntarily simplified their pricing by removing jargon and replacing multi-buy offers with simple regular prices (Thomas, 2016). 2 Online estate agents champion simple flat fees (Hammond, 2018), NPower energy claim 'we're making our tariffs simpler,' 3 Santander bank advertises 'savings made simple,' 4 and Ryanair advertises 'low fares, made simple' (Faull, 2015). Furthermore, firms with simple branding outperform their competitors (Siegel and Gale, 2017), which suggests that the existing literature overstates firms' incentives to obfuscate. We find this to be true and provide a new explanation for firms to voluntarily reduce obfuscation. We also identify market characteristics that make such behaviour more likely, with strong regulatory implications.
We develop a duopoly framework in which sellers independently select a price and an obfuscation level. Aggregate obfuscation in the market determines the fraction of consumers that understand prices. Informed consumers, who understand prices, buy from the cheapest seller. Uninformed consumers, who cannot understand prices, are divided into two types. Some uninformed consumers purchase from the firm with the lowest obfuscation, whilst the remainder buy randomly. This division follows an exogenous proportional rule that we interpret as the degree of complexity aversion. This specification enriches the standard random purchasing rule, which is a special case when we set complexity aversion to zero.
Two types of obfuscation are considered. In the first model, prices and obfuscation are simultaneously adjustable for sellers. For instance, retailers naturally choose the quantity of dimensions of a pricing scheme when selecting prices, and comparing products with more dimensions is more challenging for consumers (Iyengar and Kamenica, 2010). In the second model, firms choose their obfuscation level before selecting their price to reflect types of obfuscation that cannot be adjusted as quickly as prices. Obfuscation in this model could include the complexity of a website or in-store promotional materials.
We show that introducing complexity aversion generates novel dimensions of competition. Sellers now compete to offer the simplest alternative, in addition to the lowest price, which leads to lower obfuscation in the market. This enables more consumers to act as informed buyers, which stimulates price competition. For a class of parameter values for consumer sophistication, 5 obfuscation can be eliminated by market forces. This benefits all buyers. However, when obfuscation is not fully eradicated, new distributional concerns can arise. For instance, when firms commit to obfuscation before prices, consumers who buy the simplest product pay the highest price in the market. However, their complexity aversion generates lower prices for other types of consumers.
Following the literature review, Section 2 outlines the main model and evaluates the rationality of complexity aversion (Section 2.2.3). We consider the simultaneous game first because this timing structure illustrates the effects of complexity aversion most simply and acts as a point of comparison with the sequential model. In Section 3 we discuss the main results and policy implications. Section 4 concludes.

Related literature
This article bridges the economic psychology literature on complexity aversion with the strategic obfuscation and bounded rationality literatures in Industrial Organization, where it is well-established that firms may find obfuscation profitable (Ellison, 2005;Gabaix and Laibson, 2006;Spiegler, 2006;Carlin, 2009;Grubb, 2015;Heidhues et al., 2017). 6 Two main theoretical approaches for consumer behaviour have been proposed. Firstly, a clearing-house structure: Conditional on firms' obfuscation efforts, some consumers are confused and cannot understand any prices, whilst others understand everything (Carlin, 2009;Piccione and Spiegler, 2012). The proportion of confused buyers, who typically buy randomly, increases with obfuscation. Secondly, search-theoretic models in which consumers engage in costly search. Obfuscation directs the order of search and increases the cost per search, reducing aggregate search (Wilson, 2010;Ellison and Wolitzky, 2012). Our model sits between these two approaches. The structure is rooted in a clearing-house set-up as consumers understand all or none of the prices. However, complexity averse consumers are attracted to the lowest obfuscation seller, which connects to directed search.
The closest related work is the analysis of framing effects (Salant and Rubinstein, 2008). Piccione and Spiegler (2012) allow firms to choose a price and a frame. Buyers are initially assigned to a random default seller and the probability that consumers can compare prices decreases when firms use different frames, which generates switching inertia. Spiegler (2014) generalizes their framework to study the analytical properties of consumer choice functions. Gaudeul and Sugden (2012) also consider consumers who cannot compare prices in different frames. They study the heuristic that uninformed consumers buy from the cheapest firm that uses the most common frame, which restricts the use of individuated framing unless firms can cooperate (Crosetto and Gaudeul, 2017).
Our paper develops in the opposite direction; some frames are intrinsically more complex to understand even if sellers choose the same frame. Furthermore, our buyers do not 5 More specifically, for a class of values for the fraction of informed consumers for each level of aggregate obfuscation by sellers. 6 See Spiegler (2011) for a textbook treatment of Bounded Rationality in Industrial Economics. simplify their decision process ex ante. 7 Instead, confused consumers prefer firms that obfuscate less. Therefore, the counter-obfuscation forces we study operate at the firm level as firms compete for complexity averse consumers. Gaudeul and Sugden's (2012) operates at the market level, as firms coordinate to a common format. The two approaches provide complementary but distinct explanations for market forces to restrict obfuscation.
Whilst very different in focus, our paper is closely related to Chioveanu and Zhou (2013) who comprehensively analyse the effects of two sources of consumer confusion: individuated framing and complex framing. They study the effect of greater competition on framing choices and show how competition can harm consumers. Notably, their equilibria are robust to a consumer bias towards simple framing but they do not explore this. Our work complements Chioveanu and Zhou (2013) by fixing complex framing as the main source of consumer confusion and analysing the important competitive, welfare and policy implications of complexity aversion. In Section 2.1 we state how our model nests part of their framework and position the model precisely within the literature.
Other reasons proposed within the literature for firms to reduce obfuscation stem from asymmetries in production technologies (Dahremö ller, 2013;Wenzel, 2014) and (exogenous) market prominence Wenzel, 2014, 2015). In our framework, firm asymmetries are not needed.

The model
Consider a perfect information game of competition between two identical firms who sell a homogeneous product to a unit mass of buyers. Each buyer will purchase one unit of the product at any price not exceeding their reservation threshold, normalized to 1. Production costs are symmetric and normalized to zero, with no capacity constraints. Firms independently select a price and an obfuscation level (k), where we follow the literature by limiting obfuscation to High (H) or Low (L). The combination of firms' obfuscation efforts determines market complexity.
For each level of market complexity, each consumer is informed or uninformed. Let /ðk i ; k j Þ denote the function that specifies the fraction of informed consumers, for each combination of obfuscation choices. Define /ðL; LÞ ¼ l L ; /ðL; HÞ ¼ /ðH; LÞ ¼ l M ; /ðH; HÞ ¼ l H as the fraction of informed buyers. Informed consumers buy from the lowest priced seller. Uninformed consumers cannot compare prices. Therefore, a fraction of uninformed consumers, d 2 ½0; 1, buy from the firm with the lowest obfuscation, with equal sharing at ties. The remaining ð1 À dÞ uninformed consumers buy randomly. d is exogenous and captures the degree of complexity aversion amongst consumers. We assume that when obfuscation increases fewer consumers are informed: Obfuscation plays two roles. Firstly, each firm's obfuscation contributes to market complexity, which determines the fraction of informed consumers. This is the standard role 7 Papi (2015) and Bachi and Spiegler (2018) also present models in which consumers simplify their decision process ex ante due to tradeoff avoidance.
within the literature. Secondly, the relative obfuscation of each firm determines the allocation of uninformed buyers. In our first model (Section 2.1), firms select obfuscation and prices simultaneously. In our second model (Section 2.2), firms select obfuscation before competing in prices. Distinguishing between these cases has both technical and economic significance. From a technical perspective, the sequential game allows firms to condition prices on the obfuscation decisions of all sellers. In the simultaneous model, firms set prices based on expectations of their rival's obfuscation. From an economic perspective, the frameworks capture different types of obfuscation. Before solving the model, several remarks regarding the literature are helpful. Firstly, if we ignore obfuscation and all consumers are informed, we restore Bertrand competition. Secondly, if we ignore obfuscation but allow some consumers to be uninformed, the model collapses to Varian (1980) price competition. Thirdly, if we change the source of consumer confusion such that 1 ¼ l L ¼ l H > l M , the simultaneous model fits with Piccione and Spiegler (2012) and Gaudeul and Sugden (2012). Gaudeul and Sugden (2012) study aversion to individuated framing when n (number of firms) ! 3. In contrast, we consider confusion from complex framing ðl L > l M > l H Þ, allow l L 1 and introduce complexity aversion: d > 0, with n ¼ 2.
Fourthly, ignoring complexity aversion: d ¼ 0, and imposing l L ¼ 1, captures Chioveanu and Zhou's (2013, Proposition 2) duopoly when l M > l H . They also allow l H > l M and n ! 3, consistent with their focus on framing as competition increases. Notably, their main results are robust to a bias towards simple framing but they do not study the implications. 9 In contrast, we fix the source of consumer confusion: l L > l M > l H , allow: l L 1, and focus on the important effects of complexity aversion: d > 0. The restricted case: d ¼ 0; l L ¼ 1, acts as our benchmark for analysis to illustrate the importance of these restrictions for generating previous results. Fifthly, if firms vary in obfuscation in the sequential model, they choose prices with uneven shares of uninformed buyers, which captures Narasimhan (1988). Pricing in the sequential model also relates to Gu and Wenzel (2014) when d ¼ 0, except they assume one exogenously appointed 'prominent' seller receives a larger share of uninformed consumers independently of price and obfuscation. Our firms are ex ante identical but the lower obfuscation firm becomes 'prominent' endogenously in the sense that they receive a larger share of uninformed consumers when d > 0.

Simultaneous obfuscation and pricing
The simultaneous game unfolds over two stages. In period 1, firms choose prices and obfuscation. In period 2, consumers purchase according to their type. Equilibrium depends on the degree of complexity aversion ðdÞ exhibited by uninformed buyers.
We begin with the case where the degree of complexity aversion is small: d < d c , before considering the case with stronger complexity aversion: d ! d c , and exploring the importance of this critical threshold.
Proposition 1 For d < d c firms follow mixed strategies in prices and obfuscation: defines the probability firms select low obfuscation. When 9 Let n L and n H denote the number of firms that use frames L and H, respectively, who jointly offer the lowest price for each frame. Consumers choose a frame L firm with probability: UðnL;nH Þ nL , and a frame H firm with probability: ½1ÀUðnL;nH Þ nH , where Uðn L ; n H Þ ! nL nLþnH .
low obfuscation is selected, a price p 0 is drawn randomly from a distribution F L ðp 0 Þ. When high obfuscation is selected, a price p is drawn randomly from a distribution F H ðpÞ. The price distributions have adjacent supports such that SuppF L ðp 0 Þ ¼ ½p l ; p m ; Supp F H ðpÞ ¼ ½p m ; 1.
In equilibrium, sellers randomize their price and obfuscation. The intuition follows that sellers prefer to choose high obfuscation to soften price competition. However, if both firms choose high obfuscation, a seller prefers to deviate to low obfuscation and undercut the rival's price (Chioveanu and Zhou, 2013). This increases the amount of informed buyers, which the firm subsequently attracts, and increases the firm's share of uninformed buyers due to complexity aversion. These competing incentives induce sellers to randomize their obfuscation. The presence of informed and uninformed consumers also induces firms to randomize their price to prevent their competitor from undercutting and stealing the informed consumers (Varian, 1980).

Equilibrium payoffs and pricing
Let the expected payoff to firm i, given their priceobfuscation combination (k i , p i ), be written p i ðk i ; p i Þ.
Lemma 1 For d < d c , the price-obfuscation combination ðH; 1Þ belongs to the equilibrium mixed strategy.
All proofs are given in the Appendix. A seller charging the maximum price only attracts uninformed consumers, which fixes the highest equilibrium price at the reservation price. A less competitively priced seller benefits most from confusing consumers. That is, If the rival also chooses high obfuscation, complexity averse consumers and random purchasers are shared equally. If seller i reduces his price to p < 1, he also attracts informed consumers with probability ½1 À F H ðpÞ. If the rival chooses low obfuscation, only random purchasers buy from the high obfuscation seller. Equilibrium requires that a high obfuscation firm is indifferent between charging 1 and any other price p in the support of F H ðpÞ: Equally, the firm must be indifferent between ðH; 1Þ and ðL; p 0 Þ, where p 0 is any price in the support of F L ðp 0 Þ: When both firms choose low obfuscation, complexity averse consumers and random purchasers are shared equally. Firms compete in prices for informed buyers. When the rival selects high obfuscation, the low obfuscation firm secures all complexity averse consumers, all informed consumers and half of the random purchasers. Solving (3) yields explicit solutions for p l and p m where F H ðp m Þ ¼ 0; F L ðp m Þ ¼ 1 and F L ðp l Þ ¼ 0.
The price distributions must have adjacent supports. The reason that the supports cannot be disjoint is similar to Varian's (1980) explanation for the absence of a gap within the support of a single price distribution: Profit would increase by deviating upwards to a price in the gap. More precisely, a seller would earn higher profit by choosing low obfuscation and increasing their price from the upper bound of F L ðp 0 Þ until the lower bound of F H ðpÞ, which yields the same demand but at a higher price. We show below that an intersection with several prices cannot exist because a firm with a higher price requires that more consumers are confused.

Equilibrium obfuscation
We can now derive the optimal obfuscation strategy and demonstrate that a firm will never choose a price from the support of the distribution associated with the other level of obfuscation. This translates into: p i ðH; pÞ ! p i ðL; pÞ and p i ðL; p 0 Þ ! p i ðH; p 0 Þ. A sketch of the proof (contained in the Appendix) is as follows. From the adjacency of the price supports, the firm is indifferent between low and high obfuscation at the boundary price: p m . Therefore, at p m the two conditions above for optimal obfuscation hold with equality. Solving either condition yields a closed form expression for the probability of low obfuscation: , which can be used to confirm the equilibrium obfuscation-price strategy. We now characterize the optimal strategy when d ! d c .
Proposition 2 For d ! d c firms choose low obfuscation. Prices are drawn from the distribution: Proposition 2 restores Varian's (1980) classic model of sales as a special case when 2.1.3 Profit, welfare and analysis We now examine the effects of complexity aversion on competition and welfare. Policy implications are considered separately in Section 3.1. Expected profit can be written: Proposition 3 When prices and obfuscation are simultaneous, the effects of complexity aversion are: i. For d < d c , higher complexity aversion ðdÞ increases the probability of low obfuscation, reduces the lower bound of the lowest price distribution and increases price dispersion. Average prices and firm profit decrease. ii. For d ! d c , an increase in complexity aversion has no impact on pricing, profit or obfuscation. In the benchmark case ðd ¼ 0; l L ¼ 1Þ, firms randomize their price and obfuscation. When we allow some consumers to always be confused ðd ¼ 0; l L < 1Þ, the probability of low obfuscation increases and profit decreases. Firms are more willing to choose low obfuscation because more consumers are always confused.
Introducing complexity aversion ðd > 0; l L ¼ 1Þ increases the probability of low obfuscation because the cost of high obfuscation, in terms of the expected reduction in demand, increases. This creates more informed buyers, which incentivizes firms to make deeper price cuts and reduces profit. Importantly, a low obfuscation equilibrium ðk L ¼ 1Þ cannot exist when l L ¼ 1 if some uninformed consumers buy randomly ðd < 1Þ. The intuition is if both firms choose low obfuscation, Bertrand competition drives profit to zero. 10 By deviating to high obfuscation, a firm generates uninformed consumers and earns positive profit from his share of the random purchasers. In the extreme case where no uninformed consumers buy randomly ðd ¼ 1Þ, a firm that deviates to high obfuscation receives zero demand. Therefore, equilibrium profit is zero and sellers become indifferent between low obfuscation and deviating to high obfuscation.
In the general case: l L < 1; d > 0, increasing complexity aversion ðdÞ increases the probability of low obfuscation and reduces profit at a faster rate than when l L ¼ 1. Firms are less reluctant to choose low obfuscation because more consumers are already confused and the marginal benefit from one firm using high obfuscation (l L À l M ) is smaller. Therefore, complexity aversion has stronger effects in markets where more consumers are always uninformed. A low obfuscation equilibrium is also possible and exists whenever d ! d c .
Remark 1 In the simultaneous game with d < 1, high obfuscation can only be eliminated by complexity aversion if some consumers are always confused: l L < 1.
The intuition is when l L < 1, firms earn positive profit in a low obfuscation equilibrium due to the presence of uninformed buyers and this payoff can exceed the (positive) payoff from deviating to high obfuscation. As discussed above, this cannot occur when l L ¼ 1 because profit in a low obfuscation equilibrium is zero and deviating to high obfuscation generates strictly positive profit. The interpretation for d ¼ d c is clearer when rewritten as: dð1 À l M Þ ¼ l L À l M . The LHS corresponds to the value of complexity averse consumers and the R.H.S. corresponds to the marginal effect of obfuscation. When the benefit from high obfuscation is equal to the cost (in terms of the foregone demand), high obfuscation is not profitable. This result is important because market forces can eliminate obfuscation and existing studies that neglect complexity aversion systematically overestimate obfuscation incentives.
The pro-competitive effect of complexity aversion is intuitive from the pricing analysis but the precise forces require explanation. Firstly, complexity aversion has a direct effect on profit because these consumers inadvertently buy at the lowest price, which erodes profit. Secondly, complexity aversion generates a positive market externality by incentivizing firms to reduce their obfuscation, which allows more consumers to understand prices and erodes profit further. We decompose the Direct and Externality effects in more detail later.
Example 1 Let l L ¼ 0:75; l M ¼ 0:5; l H ¼ 0:25. Figure 1 demonstrates the probability that each firm chooses low obfuscation. d c ¼ 0:5. Figures 2 and 3 indicate the price distributions for d ¼ 0:25 and d ¼ 0:4, respectively. The solid (dashed) curve indicates the price distribution for a low (high) obfuscation seller. When complexity aversion is larger (Fig. 3), the probability of low obfuscation is higher and price competition is stronger. p m increases because high obfuscation firms require higher prices to compensate for the loss of complexity averse buyers.

Sequential obfuscation and pricing
In the simultaneous environment, firms that obfuscate less charge lower prices. Therefore, consumers who buy from the least obfuscating firm buy at the lowest price and profit decreases with complexity aversion. One might suspect that in an alternative model, where the least obfuscated products are most expensive, the pro-competitive effects of complexity 10 See Vives (2001), Ch. 5 for a textbook treatment of the Bertrand framework.
aversion would disappear. We now show that, surprisingly, this reasoning often fails. In period 1, firms select their obfuscation level. In period 2, obfuscation decisions become common knowledge and firms choose prices. In period 3, consumers buy as before. We solve the game using backward induction. The following definition aids the discussion.  Definition 1 Captive Consumers: The captive consumers for a firm correspond to the proportion of buyers that are guaranteed to buy from that firm at any price not exceeding their reservation threshold, once obfuscation decisions have been committed.
When firms select the same obfuscation level, captives are distributed equally. This produces a Varian (1980) style price equilibrium (Section 2.2.1). When firms differ in obfuscation, one seller has more captives when setting prices. This produces a Narasimhan (1988) style price equilibrium (Section 2.2.2).

Symmetric pricing
Consider first the case where both firms select low obfuscation. Lemma 2 establishes several well-known results.
Lemma 2 There exists no pure strategy Nash equilibrium in prices. For any /ðk i ; k j Þ 2 ð0; 1Þ all firms earn positive profit and compete in price distributions bounded from above by 1. If both sellers choose high obfuscation, the lower bound on prices is higher and prices are less dispersed than if both sellers choose low obfuscation.
A pure strategy equilibrium cannot exist due to standard undercutting incentives and the presence of uninformed consumers guarantees positive profit (Varian, 1980). At the reservation price, the firm is definitely more expensive than the rival and the payoff can be written: Each firm must be indifferent across all prices in the support of the price distribution, G L ðpÞ, such that: Firms trade-off charging a higher price to exploit captive demand with charging a lower price to increase the probability of attracting informed consumers. In equilibrium these tensions balance and the minimum price is: . Solving (5) yields:  ; 1 h i . Price competition is weaker when fewer consumers are informed. Therefore, average prices are higher and price dispersion is lower under high obfuscation. This illustrates the collective incentive for firms to obfuscate.

Asymmetric pricing
Consider now the pricing strategy when firms adopt different obfuscation levels. Captive consumers are unequally distributed, which produces a mass point in the distribution for the low obfuscation firm at the reservation price (Narasimhan, 1988). The high obfuscation rival chooses prices strictly below the reservation price. Fix the profit of the low obfuscation firm, firm i, at the reservation price. The firm attracts only captive consumers, which yields a payoff: The mixed strategy equilibrium makes the firm indifferent between any price in the support: Solving for G j ðpÞ yields the probability distribution over prices for the high obfuscation firm, defined over ð1þdÞð1Àl M Þ 1þdþl M ð1ÀdÞ ; 1 h . To compute the price distribution for the low obfuscation firm, write a similar indifference condition for the rival at the minimum price, noting that the reservation price is not strictly contained in its support. At the lower bound, the firm is guaranteed all informed consumers and half of the random purchasers: Solving for G i ðpÞ yields the optimal price distribution for the low obfuscation firm, defined over a near-identical support: ð1þdÞð1Àl M Þ 1þdþl M ð1ÀdÞ ; 1 h i , with a mass point at 1 of: 2dð1Àl M Þ 1þdþl M ð1ÀdÞ . It can be demonstrated that the price distribution of the low obfuscation firm is higher in terms of first-order stochastic dominance (see Narasimhan, 1988). The low obfuscation seller is less willing to compete for informed consumers because of his monopoly power over complexity averse consumers.
Remark 2 In the sequential model, the lowest obfuscation firm has the highest (average) price. In the simultaneous model, the lowest obfuscation firm always has the lowest price.
The mass point reflects the value of complexity averse consumers relative to the maximum demand the seller could obtain if he also offered the lowest price. It can be interpreted as the probability that the headline price is charged. Prices below the headline reflect 'sale' prices (Spiegler, 2011). The low obfuscation firm randomizes over headline and 'sale' prices but the high obfuscation firm only randomizes over 'sale' prices. This is consistent with the observation that firms vary in their use of discounting. The value of the mass point also increases with d and decreases with l M When complexity aversion is stronger, more consumers are captives for the low obfuscation firm, which increases the cost of competing for informed buyers. When fewer consumers are informed, the incentive to compete in prices is weaker. Proposition 4 summarizes these equilibria: Proposition 4 The pricing equilibria in period 2 of the sequential game can be summarized as follows: i. If obfuscation choices are identical (k), each firm draws a price according to the associated price distribution function G k ðpÞ, defined over ½ p k ; 1. ii. When obfuscation choices vary, each firm selects prices according to asymmetric probability distribution functions. The low obfuscation firm has an atom at 1. The high obfuscation firm sets prices strictly below 1.
Example 2 Following Example 1, let l L ¼ 0:75; l M ¼ 0:5; l H ¼ 0:25. Suppose d ¼ 0:5. Figure 4 shows the probability distributions over prices when both firms choose low (solid curve) or high (dashed curve) obfuscation. Figure 5 shows the probability distributions when firms differ in obfuscation. The solid (dashed) curve indicates the low (high) obfuscation seller.

Rationality of complexity aversion
At this point, a natural question is why consumers exhibit complexity aversion? This is distinct from the heavily researched question of why some consumers fail to buy at the lowest price? 11 If the least obfuscated products are always cheapest (as in the simultaneous model), this behaviour is easily rationalized. Consumers who cannot understand prices learn that obfuscated products are more expensive and avoid them. Similarly, in Gaudeul and Sugden (2012) where 1 ¼ l L ¼ l H > l M , aversion to individuated framing is rational because firms that use common standards face tougher competition with each other and therefore charge lower prices. However, in the sequential model, where the least obfuscated products are most expensive, rationalizing complexity aversion is more challenging. Here we outline several explanations. Firstly, from a theoretical perspective, the most obfuscated products are always most expensive in the simultaneous setting. However, the most obfuscated products are only more 11 See Grubb (2015) for an excellent overview of the literature on this topic.

PRICING AND OBFUSCATION WITH COMPLEXITY AVERSE CONSUMERS expensive on average in the sequential setting. Therefore, the negative correlation may not be visible to consumers. Secondly, for uninformed consumers to learn that obfuscated products are cheaper, consumers need to repeatedly buy both types. However, recent evidence indicates that consumers often fail to learn of the sub-optimality of their choice because they do not consider the counter-factual alternative (Wilson and Waddams Price, 2010;Huck and Wallace, 2015).
Thirdly, consumers may derive additional benefits from avoiding complex products. For instance, more complicated price frames may be costlier for consumers to understand in terms of effort, inducing buyers to select the simpler alternative. Consumers may also prefer to use a 'fast' decision-making heuristic of choosing the simplest alternative to avoid the 'slow' and intellectually taxing price-comparison process (Spenner and Freeman, 2012). 12 Recent evidence also indicates that consumers perceive obfuscated products to be unfair and consider obfuscating sellers to be untrustworthy (Homburg et al., 2014). Therefore, consumers choose simple alternatives that they trust more. These explanations are also consistent with evidence that consumers will pay a price premium for simplicity (Homburg et al., 2014;Siegel and Gale, 2017). Finally, confused consumers may incorrectly estimate that complex products are most expensive, which induces buyers to choose the simplest alternative (Homburg et al., 2014).
We now characterize the optimal obfuscation strategy in period 1. Firms face competing incentives. Higher obfuscation softens price competition but reduces the probability that the firm attracts complexity averse consumers. The relative strength of these incentives depends on the parameters governing consumer sophistication ðl L ; l M ; l H Þ and complexity aversion ðdÞ. We outline the equilibria before evaluating the incidence of complexity aversion. 12 We are grateful to the anonymous referees for suggesting these two explanations.
R. EDWARDS 2.2.4 Symmetric obfuscation equilibria First consider pure strategy symmetric equilibria. Let the expected payoff for firm i (j), given the obfuscation choices of each seller, be written p i fk i ; k j g ðp j fk i ; k j gÞ. For a low obfuscation equilibrium, we require: p i fL; Lg ! p i fH; Lg, such that: Proposition 5 A low obfuscation equilibrium is more likely when: i. The degree of complexity aversion ðdÞ is high.
ii. The natural level of consumer sophistication ðl L Þ is low.
An increase in the natural level of consumer sophistication ðl L Þ makes low obfuscation less likely, for two reasons. Firstly, a higher level of market complexity is required to achieve the same level of consumer confusion. Secondly, for a fixed l M , the marginal effect of one firm deviating to high obfuscation ðl L À l M Þ increases, which strengthens firms' incentives to choose high obfuscation.
Remark 3 In the sequential game, a low obfuscation equilibrium may fail to exist for all levels of complexity aversion ðdÞ.
Consider now a high obfuscation equilibrium. This requires p i fH; Hg ! p i fL; Hg and translates into: Proposition 6 A high obfuscation equilibrium is more likely when: i. The degree of complexity aversion ðdÞ is low.
ii. The intermediate level of consumer sophistication ðl M Þ is high.
iii. The minimum level of consumer sophistication ðl H Þ is low.
The intuition for (8) is clearer when rewritten as: ðl M À l H Þ ! dð1 À l M Þ. Intuitively, high obfuscation is sustained when the marginal effect of obfuscation exceeds the value of complexity averse consumers. High obfuscation is also more easily sustained when l M is higher. We provide three reasons. First, higher obfuscation is required to achieve the same level of consumer confusion. Second, the marginal effect of one firm deviating from high obfuscation ðl M À l H Þ increases. Therefore, price competition would be more intense if any firm deviated. Third, more informed consumers implies fewer complexity averse consumers, which reduces the gains from deviating to low obfuscation. The intuition for a high obfuscation equilibrium becoming more likely when l H decreases follows from the same arguments, approached from the opposite direction.
Remark 4 In the sequential game, a high obfuscation equilibrium is sustained for any degree of complexity aversion ðdÞ if l M À l H > 1 À l M .

Mixed strategy obfuscation equilibrium
There exists parameter constellations where a symmetric pure strategy equilibrium does not exist. Instead, there exists an asymmetric pure strategy equilibrium and a symmetric mixed strategy equilibrium. Asymmetric equilibrium requires: p i fL; Hg ! p i fH; Hg and p j fL; Hg ! p j fL; Lg and the pricing stage mirrors the asymmetric equilibria in Proposition 4. We focus on the case where firms cannot coordinate such that sellers follow symmetric mixed strategies. 13 Complexity aversion disrupts the high obfuscation equilibrium but fails to discipline firms to low obfuscation. Let K L denote the probability that each firm selects low obfuscation where K H ¼ 1 À K L . In equilibrium the firm is indifferent over these pure strategies: Insert the relevant payoffs and rearrange to yield: As in the simultaneous model, we restrict K L 2 ½0; 1. For K L 0 ð! 1Þ, a high (low) obfuscation equilibrium exists.
Proposition 7 In a mixed strategy obfuscation equilibrium, the probability placed on low obfuscation ðK L Þ increases with the degree of complexity aversion ðdÞ.
Proposition 7 is the sequential model analogue of Proposition 3 in the simultaneous game.
Following an example, the models are compared in detail.
Example 3 Suppose l L ¼ 0:75; l M ¼ 0:5 and l H ¼ 0:25. The probability of low obfuscation for varying degrees of complexity aversion ðdÞ is given by the solid curve in Fig. 6. For d 0:5, a high obfuscation equilibrium exists. As d increases, the incentive to compete in 13 Full details of the asymmetric equilibrium are provided in the Appendix. There is no systematic ranking of the asymmetric pure strategy equilibrium and symmetric mixed strategy equilibrium in terms of welfare.
obfuscation grows until firms randomize according to KL. When all uninformed consumers are complexity averse ðd ¼ 1Þ, firms randomize equally between high and low obfuscation. There exists no low obfuscation equilibrium. If consumers are less sophisticated: l L ¼ 0:45; l M ¼ 0:3; l H ¼ 0:15, a high obfuscation equilibrium is overturned by d > 0:21 and a low obfuscation equilibrium arises whenever d > 0:66, as illustrated by the dashed curve in Fig. 6. 2.2.6 Profit, welfare and analysis To maximize comparability with the simultaneous model, we follow the same analytical structure. 14 In the benchmark case ðd ¼ 0; l L ¼ 1Þ firms choose high obfuscation. This differs from the simultaneous game where firms randomize their obfuscation because the correlation between prices and obfuscation is reversed. In the simultaneous game, a firm with a lower price chooses low obfuscation to increase the amount of informed buyers. However, in the sequential game, the pricingrelated incentive to choose low obfuscation disappears because a low obfuscation firm charges the highest (average) price. Allowing l L < 1 has no substantive effect when d ¼ 0 because firms share a common incentive to maximize consumer confusion, regardless of the amount of consumers that are always confused. In contrast, reducing l L < 1 in the simultaneous game increases the probability of low obfuscation.
Introducing complexity aversion ðd > 0; l L ¼ 1Þ, weakens firms' obfuscation incentives. Depending on the values for consumer sophistication and complexity aversion, a mixed strategy equilibrium may exist or a high obfuscation equilibrium may persist. Consistent with the simultaneous model, a low obfuscation equilibrium cannot exist when l L ¼ 1.
In the general case: l L < 1; d > 0, the probability of low obfuscation increases (or remains 0) with complexity aversion ðdÞ and a low obfuscation equilibrium becomes possible but only for some parameter values for consumer sophistication. This reinforces two important insights from the simultaneous model: High obfuscation can only be eliminated when some consumers are always confused and complexity aversion incentivizes lower obfuscation. However, there are four important differences.
Firstly, the sequential model admits a wider range of obfuscation equilibria because a high obfuscation equilibrium never exists in the simultaneous game. Secondly, a low obfuscation equilibrium may not exist for any degree of complexity aversion in the sequential model but always exists in the simultaneous model when d ! d c . The intuition follows that even when all uninformed consumers are complexity averse ðd ¼ 1Þ, a firm in the sequential game may earn higher profit by deviating to high obfuscation, to soften price competition, and selling to informed buyers. This cannot occur in the simultaneous model because a high obfuscation firm charges the highest price and would receive zero demand.
Thirdly, if l M À l H > dð1 À l M Þ, complexity aversion has no substantive effect in the sequential game but always increases the probability of low obfuscation in the simultaneous game. The explanation is that the incentive to choose low obfuscation grows with complexity aversion but this need not overturn the high obfuscation equilibrium in the sequential model. In contrast, firms in the simultaneous game place positive probability on low obfuscation without complexity aversion. Therefore, strengthening the incentive to choose low obfuscation increases the probability of low obfuscation.
14 We are grateful to an anonymous referee for suggesting this structure.
Fourthly, the intuition for the mixed strategy in obfuscation differs: Firms choose low obfuscation to compete for complexity averse consumers but if both firms choose low obfuscation, price competition becomes too strong and a seller prefers to deviate to high obfuscation (even though this deviation benefits the low obfuscation firm most). In contrast with the simultaneous model, there exists no additional pricing-related incentive to choose low obfuscation.
We now evaluate the effects of complexity aversion on profit, which are more complicated in the sequential framework because the relative magnitudes of the direct and externality effects come into play. Prices and obfuscation are negatively correlated. Therefore, complexity averse consumers buy at the highest (average) price, which increases profit (Direct effect). However, complexity aversion continues to incentivize lower obfuscation, which increases the fraction of informed buyers and reduces profit (Externality effect). We characterize the circumstances under which complexity aversion harms firms before discussing consumer welfare.
Proposition 8 When obfuscation and prices are sequential, the effect of complexity aversion on profit is: i. Profit decreases if complexity aversion is sufficient to generate a low obfuscation equilibrium. ii. If a low obfuscation equilibrium is not obtained: a. For l M þ 2l H 1, an increase in complexity aversion always reduces profit.
b. For l M þ 2l H > 1, an increase in complexity aversion may increase or decrease profit depending on parameter values for consumer sophistication.
Without complexity aversion, all firms select high obfuscation. If complexity aversion causes a shift from high to low obfuscation equilibrium, which is equivalent to an increase in the fraction of informed buyers in Varian (1980), profit decreases because price competition intensifies. In the intermediate case where firms randomize their obfuscation, welfare analysis is more complicated. A sufficient condition for profit to decrease with complexity aversion is l M þ 2l H 1. One might wonder when this condition would be satisfied? In practice, this condition fits well with many retail markets. For example, the Advertising Standards Authority report that only 23% of consumers could identify the total cost of broadband contracts on first viewing (ASA, 2016).
In markets where consumers are more informed, such that l M þ 2l H > 1, we are confined to numerical analysis. The absolute and relative values of the consumer sophistication parameters interactively determine the direct and externality effects. Numerical analysis indicates that for a wide range of parameter values the externality effect dominates, causing profit to decrease with d. However, this need not always be the case. This paradox is striking. Complexity averse consumers pay the highest price, yet complexity aversion can reduce profit. Furthermore, there exists parameter values where profit is higher when obfuscation is lower and more consumers are informed. The explanation is that the additional profit from exploiting complexity averse buyers outweighs the strengthening of price competition from lower obfuscation. Therefore, profits are not always higher in more obfuscated markets.
2.2.7 Consumer welfare Our metric of consumer welfare has been solely monetary. As discussed, a general measure is inherently sensitive to the specification of the utility function. It is easy to imagine that consumers may gain additional utility from engaging with a less obfuscated marketplace. In the simultaneous game, this type of additional utility has no impact on the results: Consumers are always better off when complexity aversion is higher. However, in the sequential case this need not be true.
Under a low obfuscation equilibrium in the sequential model, complexity averse consumers buy at the same price as their random-purchase counterparts and all consumers are better off due to the externality effect of complexity aversion. However, when a low obfuscation equilibrium does not arise, complexity averse buyers pay the highest (average) price and the total prices paid by all consumers need not decrease. Introducing additional utility when obfuscation is lower could allow both consumers and firms to benefit from complexity aversion. Firms benefit from higher prices and consumers benefit from consuming simple products. It is beyond the scope of this paper to quantify additional utility gains from purchasing simple products but this is an interesting avenue for future work.

Discussion
Our main message is that complexity aversion creates new dimensions of competition by incentivizing sellers to reduce their obfuscation. This enables more consumers to behave as informed buyers, which strengthens price competition. However, high obfuscation can generally only be eliminated if some consumers are always confused. In the simultaneous game, complexity aversion increases the probability of low obfuscation and reduces profit. In the sequential game, complexity aversion continues to increase the probability of low obfuscation but the welfare implications are less clear and two surprising outcomes emerge. Firstly, whilst complexity averse consumers purchase from the most expensive seller in the market, profit can decrease with complexity aversion because of the positive externality exerted on the market. Secondly, there exists parameter values where firms earn higher profit when obfuscation is lower. Therefore, consumers need not be better off in less obfuscated markets.
Complexity aversion also introduces a prisoner's dilemma in the sequential game. Firms could earn higher profits by collectively selecting high obfuscation but complexity aversion disciplines firms to a lower level. Therefore, the persistence of obfuscation in retail markets may be symptomatic of non-price collusion. This collusion-based argument cannot be obtained without complexity aversion because firms would have no incentive to deviate from high obfuscation.
For given parameters, firms (consumers) are generally better (worse) off in the sequential model because of the additional pricing-related incentive for firms to choose low obfuscation in the simultaneous model, which generates more informed buyers and stimulates price competition. 15 More precisely, if the marginal effect of obfuscation is non-decreasing ðl L À l M l M À l H Þ, profit is always lower in the simultaneous model. If the marginal effect of obfuscation is decreasing ðl L À l M > l M À l H Þ, we can show profit remains lower in the simultaneous model for a wide range of parameter values: d 2 ½0; l M Àl H ; l L Àl M 1Àl M , a mixed strategy obfuscation equilibrium exists in both models and systematic welfare comparisons become analytically intractable. Full details are provided in the Appendix. both models; pricing and welfare are identical. However, the degree of complexity aversion required to induce low obfuscation is always higher in the sequential model. There also exists parameter values where complexity aversion disciplines firms to low obfuscation in the simultaneous game without affecting the high obfuscation equilibrium in the sequential game. Therefore, obfuscation is more persistent when divorced from price competition.

Policy implications
3.1.1 Should regulators improve consumer sophistication? Regulators have developed a reputation for market intervention to protect and empower consumers. For instance, intervention in retail banking has motivated calls for intervention in other consumer-focused industries, such as Energy and Broadband (BBC, 2017). Consumer protection policies can be separated into two types. Some aim to improve aggregate consumer sophistication (e.g. independent price comparison website). Others focus on protecting the least sophisticated consumers (e.g. money advice services). How do these policies interact with obfuscation incentives when consumers are complexity averse? We focus on the implications for obfuscation as consumer welfare is inherently sensitive to the specification of the utility function.
Proposition 9 Policy implications in the simultaneous model can be summarized as follows: i. Policies that increase the proportion of informed consumers lead to higher obfuscation.
ii. Policies that reduce the marginal effect of obfuscation may lead to higher or lower obfuscation. Specifically: k L is increasing in l M but decreasing in l H and l L .
In the simultaneous game, sellers attempt to counteract policies that increase the fraction of informed consumers by increasing their obfuscation. Most concerning, in markets where firms do not use high obfuscation, policies to increase the natural level of consumer sophistication ðl L Þ can induce high obfuscation. Gu and Wenzel (2014) previously established that a firm may obfuscate more in response to policies that improve consumer sophistication. However, their arguments are very different and rely on an exogenous unequal sharing rule for uninformed consumers. A similar policy message emerges in the sequential game: Proposition 10 Policy implications in the sequential model can be summarized as follows: i. Policies that increase the natural fraction of informed consumers ðl L Þ can lead to higher obfuscation: A low obfuscation equilibrium becomes less likely. ii. Policies that increase the intermediate fraction of informed consumers ðl M Þ, or decrease the minimum fraction of informed consumers ðl H Þ, can lead to higher obfuscation: A high obfuscation equilibrium becomes more likely.
In both models, increasing the natural fraction of informed consumers ðl L Þ and reducing the marginal effect of obfuscation can generate higher obfuscation.
3.1.2 Should regulators encourage consumers to select simple alternatives? Policymakers may also ask whether consumers should be encouraged to buy simple products? When sellers choose prices and obfuscation simultaneously, complexity aversion benefits all consumers and reduces profit. However, new distributional concerns arise when firms choose obfuscation before prices. For a wide range of parameter values, complexity aversion reduces profit but the surplus is shared asymmetrically across consumer types: Complexity averse buyers pay the highest (average) price in the market but informed and random purchasing consumers benefit from the increase in price dispersion. Only when complexity aversion disciplines firms to low obfuscation are all consumer types guaranteed to benefit.

Conclusion
This paper provides a thorough treatment of the consequences of complexity aversion for firms' pricing and obfuscation strategies, consumer welfare and regulatory policy. Most significantly, we present a new mechanism for obfuscation to be costly for sellers and demonstrate that obfuscation can be reduced endogenously by complexity aversion in consumer choice, without requiring policy intervention. However, obfuscation can only be fully eliminated if some consumers are always confused. Surprisingly, complexity aversion need not be detrimental to consumer welfare even when this implies that these consumers gravitate towards the most expensive seller. Choosing the simplest product can also be rational. When obfuscation is instantly adjustable for firms, the simplest products are also cheapest. However, when obfuscation cannot be adjusted as quickly as prices, the situation is less clear and new distributional concerns can arise. Complexity averse consumers pay a higher average price than their randompurchasing counterparts but their choice process incentivizes firms to reduce their obfuscation. This leads to lower prices across the market.
This work also highlights a unique circumstance in which firms' profits are not always lower in less obfuscated markets. Therefore, regulatory intervention should not be motivated solely by high obfuscation. Policies to improve consumer sophistication may also be ineffective and induce higher obfuscation by sellers, even with symmetric firms. Most generally, we have exposed the sensitivity of models underpinned by a random purchasing rule for uninformed buyers and demonstrated that the existing literature systematically overestimates firms' incentives to obfuscate.

Work Values and Career Aspirations of Women Employees in Government Hospitals in Pangasinan

This study aimed to determine and analyze the extent of practice of work values and level of career aspirations of women-employees in selected government hospitals in the fifth and sixth congressional districts of Pangasinan, Philippines. The study made use of quantitative and qualitative data and descriptive correlation that looked into the relationship between the extent of practice of work values, level of aspirations and profile characteristics. Sixty nine regular women-employees with different positions were purposively selected. Data were gathered through questionnaire and analyzed using frequency counts and percentage, average weighted mean, Wilk’s A and Pearson r. It was found in the study that women-employees a) have ages within the legal age range of government employees; attended trainings/seminars relative to their work; and have monthly income commensurate to their positions; b) always practiced the work values of punctuality, honesty, respect, cooperation and industriousness; and have high level of career aspiration; c) extent of practice of work values and level of career aspiration were comparable across age, civil status, highest educational attainment, position and monthly income’ d) encountered problems with varying degrees of seriousness in the practice of work values in their respective work places; e) that significant positive correlation existed between the women-employees’ extent of practice of work values and level of career aspiration. Generally, the work values of punctuality, honesty, respect, cooperation and industry practiced by women-employees in the performance of their job have contributed to their high level of career aspiration in their present and future career status.

Introduction
Values are standard which one upholds as desirable and guide one's way of life. Living with good values often gives the bearer a sense of control of his life because he knows what he wants and where to go. Working with values and understanding their importance in one's career enables a person to fit into his profession, clients, colleagues and superiors. Some individuals find satisfaction in their job because it matches their work-related values, while some end up hopping significant to them.
Friendliness, teaching and motivating others, fun, order and harmony decrease stress in the work setting and creates healthier relationships. The rewards and fulfillment financially, morally or spiritually and recognition gives security and stability among the workers. With these characteristics equally valued in the workplace, it promotes efficiency in work. A worker with the right sense of work values is more effective and efficient than one who does not possess the same values (Calderon, 2014).
According to Articula and Florendo (2013), a person with commitment is transparent and open. He is honest, upright, probe and sincere without pretense or deceit. He also manifests loyalty and reliability that he gains the trust and confidence of his superiors, clients and co-workers. Committing one's self to the organization is definitely committing one's self to the work , staff and customers.
Moreover, people work in groups with different behaviors and social backgrounds. They use appropriate technological tools and techniques to achieve organizational goals and be able to coordinate the work among them. Thus, the human resource is considered the lifeblood of an organization. As the saying goes, that no two individuals are exactly alike, human resource in an organization varies in terms of its values, job satisfaction and commitment, in its ability to make decisions, and its performance.
The fifth and sixth congressional districts and community hospitals of Pangasinan has around 135 women employees that composed of the chief of Hospital, Section/Division Chief and down to the heads of offices/department and staff. With their mission to pursue a balanced and environmentally sound economic growth through responsible and equitable management of resources and participative governance, women employees should have unified values to work to meet the needs of every customer that comes in and goes out of the hospital.
Work values such as responsibility, accountability, honesty, respect, competence and consistency maintains the integrity of an institution. The desire for knowledge, advancement, personal growth, challenge, creativity, aesthetics and openness to change and variety takes a working group to a higher level of success. Good leadership, autonomy, decision-making, teamwork, power and authority provide a stronger foundation and strengthen the organization.
However, there are organizations where there are observable negative working attitudes of personnel as they render their services in the workplace. Some of these are disobedience from orders of supervisors, leaving the assigned work undone, idleness, absenteeism and tardiness. Collectively, these negative work values serve as constraints and impediments to higher work productivity and organizational performance.

Materials and Methods
The study was conducted to determine the extent of practice of work values of women employees in selected government hospitals in the fifth and sixth congressional districts of Pangasinan and their level of career aspiration in the performance of their duties and obligations in their respective workplace.
The descriptive correlational method of research was employed in the study since it described women employees' extent of practice of work values and level of career aspiration. It also looked into the relationship between the two variables.
The study was carried out in six (6) selected hospitals in the fifth and sixth congressional districts of Pangasinan, namely: Asingan Community Hospital, Eastern Pangasinan District Hospital, Manaoag Community Hospital, Pozorubio Community Hospital, Urdaneta District Hospital and Umingan Community Hospital.
A total of 69 women employees with permanent and/or plantilla position / item representing different positions were included in this study.
Prior to the survey proper, approval from the Hospital Administrators was sought before the administration of the questionnaire-interview guide to the respondents.
A guided-response type of questionnaire consisted of four parts which was prepared by the researcher as the data gathering instrument was pre-tested and validated. Part I elicited data on the personal profile of the respondents; Part II contained the indicator-statements which measured the respondents' extent of practice of work values in the workplace; Part III dwelt on the indicator-statements which determined the level of career aspirations of the respondents in terms of present career status and preferred career status; while Part IV consisted of possible problems encountered by the respondents in the practice of their work values.
Frequency counts and percentage distribution were used in determining respondent's profile; while frequency counts, average weighted mean and ranks were employed to determine the degree of seriousness of these problems encountered by the respondents on their practice of work values. To determine the extent of practice of work values and level of career aspiration, frequency counts and summated mean drawn from a 5 point Likert Scale was used.

Respondents' Profile
A total of 69 women employees with permanent status holding different positions in the six hospitals of Pangasinan were included in the study. The profile of respondents is presented in Tables 1 and 2: It can be gleaned from Table 1 that as to profile age, 28 or 40.6% of the respondents belonged to age range of 41-50; 24 or 34.8% fall within the age range of 51-60; 7 or 10.1% have ages 30 years and below; while 5 or 7.2% respondents for each of the age range of 31-40 and 61 and above.

Extent of Practice of Women Employees on Work Values
The distribution of respondents according to their extent of practice of work values with the corresponding mean ratings of their responses on the different indicator-statements of each of the domains of punctuality, honesty, respect, cooperation and industry are reflected in Table 3.  Table 3 presents that generally, the women-employees in the different government hospitals always practice the work value of punctuality in their respective work places as evidenced by the overall average weighted mean of 4.59.
Particularly, the five indicator-statements of punctuality were always practice by the respondents, however, indicator on submitting reports, outputs on or before deadline, and observing work hours, break period, etc. were always practice by most or 50-51 respondents.
On the work value of honesty, Table 3 discloses that in particular most of the women employees always practice honesty in returning any belongings left by clients or co-workers in the hospital with 59 or 86% respondents practicing it; 58 or 84% is rendering services with dedication, commitment and sincerity; 54 or 78% in accepting their own actions and not blaming others; 52 or 75% in accomplishing DTR by indicating their actual time of arrival and departure from hospital; 51 or 74% in admitting mistakes that they commit.
Generally, the women employees in the different government hospitals always practice honesty in their respective work places with an average weighted mean of 4.75.
In terms of respect as one of the domains of work values, Table 3 shows that in particular, most of the women employees always practice respect in their work places by greeting with courtesy clients, visitors and co-workers (55 or 80%); by speaking in modulated voice (41 or 59%); by answering honesty and promptly (46 or 67%); by not uttering unsavory words (40 or 58%) and by controlling their temper (39 or 57%) Overall, the women-employees in the selected government hospitals always practice showing respect to their clients, visitors and co-workers as indicated by the average weighted mean of 4.60.
With regards to cooperation as a work value, on the whole, the women-employees in the selected government hospitals always practice cooperation in their respective work places as revealed by the general average weighted mean of 4.65.
Particularly, 53 or 77% respondents always practice cooperation in striving to work cooperatively with their co-workers regardless of their status; 49 or 71% in striving to show concern for their co-workers and clients; 48 or 70% in sharing knowledge/skills with their co-workers; 44 or 64% in trying to be considerate and fair in dealing with co-workers and clients.
On the work value of industry, Table 3 reveals that generally the women-employees in the different government hospitals always practice their work values of cooperation as indicated by the average weighted mean of 4.54.
In particular, 47 or 68% respondents always practice industry in rendering extra time for exigency of service; 44 or 64% in complying work assignment within a target time even without supervision and in being willing to assist their clients or co-workers in their needs; while 34 or 49% in voluntarily and actively participating in socio-cultural, spiritual and other activities.
To sum it all, the overall weighted mean of 4.63 may imply that the women-employees in the selected government hospitals in Pangasinan always practice the different work values in the performance of their duties and obligations in their respective work places.

Level of Career Aspiration of the Women-Employees
Career aspiration which refers to the present and preferred aspirations of women-employees in terms of their career expectations while working in the government hospitals are reflective of their motivation, satisfaction, expectations regarding conditions of their work and work environment in relation to their present and future career status.
The distribution of the respondents according to their responses in each of the indicators on career aspiration with the corresponding average weighted mean and overall weighted mean are reflected in Table 4. Given continuous recognition and incentives or rewards for an excellent job and more teambuilding and general Wellness activities be conducted among the hospital employees.  Table 4 shows that along present career status, 28 or 41% respondents have very high level of career aspiration when they have the ability to render service and be of significant help and assistance to sick people with commitment; 40 or 58% have high level of career aspiration when their current work provides freedom from very strict supervision and organization culture which promotes conduciveness of work environment and healthy work condition; 35 or 51% with high level of career aspiration when their work suits parents, family's idea of success and they will stay in the job.

Level of Career Aspiration in Present Career Status
On the whole, the women-employees of the selected government hospitals in Pangasinan have high level of career aspiration in their present career status as indicated in the average weighted mean of 3.96.

Level of Career Aspiration in Future Career Status
It is shown in Table 4, page 5 the distribution of respondents according to their level of career aspiration in each of the expectations regarding the conditions of their work and work environment along their future career status. Table 4 reveals that respondents claimed that they have high level of career aspiration given each of the conditions where occupation to continue having the prestige especially for women as employees in the hospital, (37 or 53.62%); higher prospect for long term security in the hospital service, (32 or 46.38%); complete/earn masteral/doctoral degrees to secure promotion in the workplace, (31 or 44.93%); career in the hospital would represent progress through increased recognition on salary (25 or 36.23%); and given continuous recognition and incentives or rewards for an excellent job and more team building and general wellness activities conducted among the hospital employees (26 or 37.68%) Generally, the women-employees in the selected government hospitals have high level of career aspiration in their future career status as reflected in the average weighted mean of 3.75.
In a summary, the overall weighted mean of 3.86 signifies high level of career aspiration of the women-employees in the selected government hospitals in Pangasinan.

Problems Encountered By Women-Employees in the Practice of Work Values in their Jobs
The distribution of respondents according to the degree of seriousness of the problems they have encountered together with the average weighted means and ranks of the problems are indicated in Table 5.

Table 5 Problems Encountered By Women-Employees in the Practice of Work Values in Their Jobs, n=69
Note It can be noted in Table 5 that there are 10 problems identified by the respondents in the practice of work values in their respective jobs.
Among the top three which were considered serious problems by the women-employees as evidenced by their average weighted mean and rank are: "Delayed action to request for repair of facilities and equipment", (AWM -3.48, Rank 1); "Delay in the requisitioning of supplies and materials", (AWM -3.42, Rank 2); and "Extra duties due to lack of manpower", (AWM -3.33, Rank 3).
Other problems that they have encountered in the practice of work values in their jobs were considered as moderately serious.

Across Profile Variables
The results of data analysis using Wilk's A on the significance of the differences between the extent of practice of work values of women-employees in their jobs across profile variables are presented in Table 6.
It can be deduced from the results that no significant difference exists on the extent of practice of women employees on work values across profile variables. The obtained multivariate Wilk's A values of all the profile variables range from .490 to .849 with significance levels ranging from .051 to .487 which are all greater than the .05 level of significance.
These findings may imply that regardless of their age, civil status, highest educational attainment, position and income, their extent of practice of the work values on their jobs are comparable. These findings may also reinforce the previous results on their extent of practice that generally, women-employees always practice the work values of punctuality, honesty, respect, cooperation and industry. Note: ns Not Significant, a Some categories were collapsed due to minimum number of cases.

Across Profile Variables
This section discusses the significance of the differences in the career level of aspiration of the women employees across profile variables. The obtained multivariate Wilk's A values together with their corresponding level of significance are presented in Table 7. Note: ns Not Significant, a Some categories were collapsed due to minimum number of cases.
It can be inferred from the results that no significant differences exists in the level of career aspiration across profile characteristics of the women employees in the selected government hospitals in the province of Pangasinan as revealed by the multivariate Wilk's A values which range from .811 to .998 with corresponding significance levels ranging from .123 to .984 which are all greater than the .05 level of significance. Thus, it can be deduced that the level of career aspiration of women employees in the selected government hospitals are the same across profile characteristics. These findings may imply that the profile characteristics of the women employees such as age, civil status, highest educational attainment, position, monthly income and seminars attended do not cause any variation or have not affected their level of career aspiration.

Relationship Between the Women Employees' Extent of Practice of Work Values on their Job and Level of Career Aspiration
This portion of the study discusses the relationship between the extent of practice of work values and level of career aspiration of women employees in the selected government hospitals in the province of Pangasinan. The obtained coefficients of correlation with the corresponding level of significance are indicated in Table 7. It can be deduced from the obtained coefficients of correlation the women employees' extent of practice of work values related to punctuality, honesty, respect, cooperation and industry as well as their overall extent of practice of work values are significantly related to their level of career aspiration in the present career status and future career status as well as their overall level of career aspiration as clearly shown by the obtained coefficients of correlation ranging from .330 to .448 with corresponding significance level that are all less than the .01 level of significance. These imply that the hypothesis of no relationship between the two variables is rejected. The significant positive correlation indicates that the greater the extent of practice of work values by the women employees in the selected government hospitals in the province of Pangasinan, the higher is their level of career aspiration in their present career status, future career status as well as their overall level of career aspiration.

Conclusions
In conclusion, the women employees in the fifth and sixth congressional district s of Pangasinan always practice the work values related to the performance of their jobs in relation to punctuality, honesty, respect, cooperation and industry. They have high level of aspiration related to their present career status and future career status. Moreover, the women employees' profile of age, civil status, highest educational attainment, position and monthly income has not influence the extent of practice of work values in their respective jobs and their present career status and future career status. Further, the significant positive correlation suggests that the greater the extent of practice of work values by the women employees , the higher is the level of their career aspiration in their present and future career status. The women employees encounter problems of various degree of seriousness in the practice of work values in the performance of their respective jobs.
