A model of endogenous growth is presented, based on productive public expenditures, and featuring some degree of income inequality, and polarization in policy preferences. The main innovation lays in the political process determining capital taxation that relies, both on voting and on "influence...

We study a growth model with two types of agents who are heterogeneous in their degree of family altruism. We prove that every equilibrium path converges to a unique steady state, and study the effect of altruism on the properties of steady-state equilibrium. We show that aggregate income is...

A fundamental question in social sciences relates to the effect of wealth inequality on economic growth. Yet, in tackling the question, researchers have had to use income as a proxy for wealth. We derive a global measure of wealth inequality from Forbes magazine's listing of billionaires and...

This paper reconciles neoclassical models of economic growth ("Solow") with the formation of social classes during economic transition ("Marx"). An environment with missing capital markets and no labor divisibility is shown to lead to a steady state with no aggregate inefficiencies, but a very...

We present evidence that ethnic fragmentation explains variations in per capita income, institutions, and schooling better than income inequality when both are treated as endogenous. To do so, we identify instruments for ethnic fractionalization and income inequality based on historical...
