Preview

Social choice theory helps to design a research strategy. Three institutional variables producing different degrees of stability and different amounts of social utility are: (1) the dispersion of voters’ preferences, corresponding to simple and complex electorates; (2) the inclusiveness of different voting and electoral rules; and (3) the number of issue dimensions in single and separate elections, corresponding to schemes of unity and division of powers.

Keywords: dispersion; division of powers; electoral rules; electorate; issue dimension; median voter; political equilibrium; social choice; social utility
