Lognormal (Re)Distribution: A Macrofounded Theory of Inequality

Abstract

We study how political competition over redistribution determines income inequality under two macrofounded premises: a) the income distribution is approximately log-normal before and after any policy intervention; and b) voters' income and turnout rates are positively related. The unique equilibrium features substantial income inequality and less than maximal redistribution, even if the voters' median income is very low. Fitting our model to the US economy, we argue that either the efficiency cost of redistribution is higher than estimates in the literature, or else US's redistributive policies are optimal for an agent richer than the median voter.
