Available in PDF, EPUB and Kindle. Book excerpt: My dissertation investigates two models of macroeconomics with heterogeneous agents. The first chapter analyzes a setup where agents are ex ante identical, yet receive idiosyncratic income shocks which make them heterogeneous ex post. A private information friction gives rise to incomplete risk-sharing as a constrained-efficient allocation. The second chapter again considers ex post heterogeneous agents: they have identical preferences but face idiosyncratic shocks to their earning capacity. There the focus is not on risk-sharing, but on the aggregate consequences for labor supply.
