I introduce money into an incomplete markets model with heterogeneous agents and uninsurable income risk. I show that … the model exhibits both non-monetary and monetary equilibria, with the latter existing when income risk is sufficiently …

-generational transmission of wealth. Financial markets are incomplete, exposing agents to both labor income and capital income risk. We show … that the stationary wealth distribution is a Pareto distribution in the right tail and that it is capital income risk …

optimally shares risks across generations exposes future generations to a share of the risk in physical capital returns. Such a … system reduces precautionary saving and increases the risk-bearing capacity of the economy. Under plausible conditions it … increases the riskless interest rate, lowers the price of physical capital, and reduces the risk premium on physical capital …

This paper examines the optimal allocation of risk in an overlapping-generations economy. It compares the allocation of … risk the economy reaches naturally to the allocation that would be reached if generations behind a Rawlsian 'veil of … ignorance' could share risk with one another through complete Arrow-Debreu contingent-claims markets. The paper then examines …

Are market and voting institutions capable of producing optimal intergenerational risk-sharing? To study this question … that take place in markets and voting institutions. Unlike most of that literature, we study both ex-ante and interim risk …-sharing. Our main conclusion is that both types of institutions have serious problems. Markets cannot generate ex-ante risk …
