Social Choice Theory
o Political process is an instrument rather than an end in itself.
o The decisive political act is a private rather than public action.
o The structure is as follows:
1. Agents are given so the issue of a normative justification of political boundaries does not arise.
2. Agents confront a given set of alternatives so agenda manipulation is not an issue.
3. Preferences of agents are given and not subject to change in the course of the political process and those preferences are causally independent of the set of alternatives.
- In operation, individual preferences they are purely ordinal, complete, and transitive.
- Social preference ordering of alternatives should be complete and transitive, Pareto-optimal, depend on only the relevant alternatives, and respect and reflect individual preferences, over and above the condition of Pareto-optimality (anonymity, non-dictatorship, liberalism, strategy-proofness).
Criticism of social choice theory: it embodies a confusion between the kind of behavior that is appropriate in the market place and that which is appropriate in the forum. The consumer is sovereign in the marketplace because he chooses between courses of action that differ only the in the way they affect him; in political choice situations, he is asked to express his preference over states that also differ in the way in which they affect others. A social choice mechanism is capable of resolving market failures that result from unbridled consumer sovereignty, but is hopelessly inadequate at redistributing welfare. The task of politics is not just to eliminate inefficiency, but to create justice--a goal to which the aggregation of political preferences is an incongruous means.
The transformation of public preferences through public and rational discussion:
- The conceptual impossibility of expressing selfish arguments in a debate about the public good and the psychological difficulty of expressing other-regarding preferences without ultimately coming to acquire them bring about that public discussion tends to promote the common good.
- Elster objects to this line of argument because not everyone will deliberate, there are time constraints, rational arguments will not align underlying values or eliminate self-interest.
What makes democracy superior are its side effects on economic prosperity. But those side effects can not be what motivate a government to pursue democracy because then society would not believe in democracy on any other ground and the side effects that come with it would not be produced.
The political process is:
1. instrumental in purpose
2. an end in itself, a good or even the supreme good for those who participate in it
3. and/or both
