June 2010Adverse Selection, Reputation and Sudden Collapses in Secondary Loan Markets
with V.V. Chari, Ariel Zetlin-Jones: w16080
Banks and financial intermediaries that originate loans often sell some of these loans or securitize them in secondary loan markets and hold on to others. New issuances in such secondary markets collapse abruptly on occasion, typically when collateral values used to secure the underlying loans fall. These collapses are viewed by policymakers as signs that the market is not functioning efficiently. In this paper, we develop a dynamic adverse selection model in which small reductions in collateral values can generate abrupt inefficient collapses in new issuances in the secondary loan market. In our model, reductions in collateral values worsen the adverse selection problem and induce some potential sellers to hold on to their loans. Reputational incentives induce a large fraction of potentia...
June 2009Risk Sharing, Inequality and Fertility
with Roozbeh Hosseini, Larry E. Jones: w15111
We use an extended Barro-Becker model of endogenous fertility, in which parents are heterogeneous in their labor productivity, to study the efficient degree of consumption inequality in the long run. In our environment a utilitarian planner allows for consumption inequality even when labor productivity is public information. We show that adding private information does not alter this result. We also show that the informationally constrained optimal insurance contract has a resetting property - whenever a family line experiences the highest shock, the continuation utility of each child is reset to a (high) level that is independent of history. This implies that there is a non-trivial, stationary distribution over continuation utilities and there is no mass at misery. The novelty of our appr...
