There is growing evidence on the roles of fairness and social preferences as
fundamental human motives, in general, as well as in voting contexts. In contrast,
models of political economy are based on sel sh-voters who derive utility solely from
own payo¤. We examine the implications of introducing voters with social prefer-
ences, as in Fehr and Schmidt (1999), in a simple general equilibrium model with
endogenous labour supply. We demonstrate the existence of a Condorcet winner for
voters, with heterogeneous social preferences (including purely sel sh preferences),
using the single crossing property of voters preferences. Relatively small changes in
the preference of voters can have relatively large redistributive consequences. We im-
plications for the size of the welfare state; regional integration; and issues of culture,
identity and immigration.
