aggregate demand curve
Thus, a drop in the price level decreases the interest rate, which increases the demand for investment and thereby increases aggregate demand. The third reason for the downward slope of the aggregate demand curve is Mundell-Fleming's exchange-rate effect. (This is known as the law of demand.). In contrast, the aggregate demand curve used in macroeconomics shows the relationship between the overall (i.e. average) price level in an economy, usually represented by the GDP Deflator, and the total amount of all goods demanded in an economy. The first reason for the downward slope of the aggregate demand curve is Pigou's wealth effect. Recall that the nominal value of money is fixed, but the real value is dependent upon the price level. This is because for a given amount of money, a lower price level provides more purchasing power per unit of currency. DEFINITION of 'Aggregate Demand'. The total amount of goods and services demanded in the economy at a given overall price level and in a given time period. It is represented by the aggregate-demand curve, which describes the relationship between price levels and the quantity of output that firms are willing to provide. Normally there is a negative relationship between aggregate demand and the price level. Also known as total spending. The most noticeable feature of the aggregate demand curve is that it is downward sloping, as seen in. There are a number of reasons for this relationship. Recall that a downward sloping aggregate demand curve means that as the price level drops, the quantity of output demanded increases. Similarly, as the price level drops, the national income increases. There are three basic reasons for the downward sloping aggregate demand curve. (Note that goods in this context technically refers to both goods and services.) Specifically, the aggregate demand curve shows real GDP, which, in equilibrium, represents both total output and total income in an economy, on its horizontal axis. Students learn in microeconomics that the demand curve for a good, which shows the relationship between the price of a good and the quantity of the good that consumers demand-i.e. are willing, ready, and able to purchase-has a negative slope. Aggregate demand is the demand for the gross domestic product (GDP) of a country, and is represented by this formula: Aggregate Demand (AD) = C + I + G + (X-M) C = Consumers' expenditures on goods and services. I = Investment spending by companies on capital goods. Therefore, the aggregate demand curve must slope downwards for different reasons. In fact, there are three reasons why the aggregate demand curve exhibits this pattern: the wealth effect, the interest-rate effect, and the exchange-rate effect. (Technically, in the context of aggregate demand, the Y on the horizontal axis represents aggregate expenditure .) As it turns out, the aggregate demand curve also slopes downwards, giving a similar negative relationship between price and quantity that exists with the demand curve for a single good.
