 Would socialism do better than capitalism regarding the ideals of equality, democracy, individual freedom, self-realization, and solidarity? This depends on the availability of workable versions of socialism that fulfill these ideals (or do so at least to a greater extent than workable forms of capitalism). A first set of proposals envision an economic system that does away with both private property in the means of production and with markets. The first version of this model is central planning. This can be understood within a top-down, hierarchical model. A central authority gathers information about the technical potential in the economy and about consumers’ needs and formulates a set of production objectives which seek an optimal match between the former and the latter. These objectives are articulated into a plan that is passed down to intermediate agencies and eventually to local firms, which must produce according to the plan handed down. If it works, this proposal would secure the highest feasible levels of equal access to consumption goods for everyone. However, critics have argued that the model faces serious feasibility hurdles (Corneo 2017: ch. 5: Roemer 1994a: ch. 5). It is very hard for a central authority to gather the relevant information from producers and consumers. Second, even if it could gather enough information, the computation of an optimal plan would require enormously complex calculations which may be beyond the capacity of planners (even with access to the most sophisticated technological assistance). Finally, there may be significant incentive deficits. For example, firms might tend to exaggerate the resources they need to produce and mislead about how much they can produce. Without facing strong sticks and carrots (such as the prospects for either bankruptcy and profit offered by a competitive market), firms might well display low levels of innovation. As a result, a planned economy would likely lag behind surrounding capitalist economies, and their members would tend to lose faith in it. High levels of cooperation (and willingness to innovate) could still exist if sufficiently many individuals in this society possessed a strong sense of duty. But critics find this unlikely to materialize, warning that “a system that only works with exceptional individuals only works in exceptional cases” (Corneo 2017: 127).
