The median voter model (direct democracy) has wide applicability, but it is
based on sel sh voters i.e. voters who derive utility solely from own payo¤. The
recent literature has pointed to fairness and concern for others as basic human mo-
tives that explain a range of economic phenomena. We examine the implications of
introducing fair voters who have a preference for fairness as in Fehr and Schmidt
(1999). Within a simple general equilibrium model, we demonstrate the existence
of a Condorcet winner for fair voters using the single crossing property of voters
preferences. In a fair voter model, unlike a sel sh voter model, poverty can lead
to increased redistribution. Mean preserving spreads of income increase equilibrium
redistribution. Greater fairness leads to greater redistribution. The introduction of
sel sh voters in an economy where the median voter is fair can have a large impact
on the redistributive outcome. An empirical exercise using OECD data illustrates
the potential importance of fairness in explaining redistribution.
