On the Dynamics of Inequality
Economic Theory 29, 291–306, 2006.
Summary. The dynamics of inequality are studied in a model of human capital accumulation with credit constraints. This model admits a multiplicity of steady state skill ratios that exhibit varying degrees of inequality across households. The main result studies nonstationary equilibrium paths, and shows that an equilibrium sequence of skill ratios must converge monotonically to the smallest steady state that exceeds the initial ratio for that sequence. This paper, in honor of Mukul Majumdar, publishes notes from 1990, which contain a different proof of the main result.
Nonpaternalistic Intergenerational Altruism
Journal of Economic Theory 41, 112-132, 1987.
Summary. The paper develops a concept of equilibrium behaviour in a model of nonpaternalistic intergenerational altruism. When each generation’s utility depends on that of at least two successors, equilibria may be inefficient.
