Damage control? analyzing policies to repair credit markets
Market-making with Search and Information Frictions
We develop a dynamic model of trading through market-makers that incorporates two canonical sources of illiquidity: trading (or search) frictions, which imply that market-makers have some amount of market power; and information frictions, which imply that market-makers face some degree of adverse selection. We use this model to study the effects of various technological innovations and regulatory initiatives that have reduced trading frictions in over-the-counter markets. Our main result is that reducing trading frictions can lead to less liquidity, as measured by bid-ask spreads. The key ...
Screening and Adverse Selection in Frictional Markets
We incorporate a search-theoretic model of imperfect competition into a standard model of asymmetric information with unrestricted contracts. We characterize the unique equilibrium, and use our characterization to explore the interaction between adverse selection, screening, and imperfect competition. We show that the relationship between an agent?s type, the quantity he trades, and the price he pays is jointly determined by the severity of adverse selection and the concentration of market power. Therefore, quantifying the effects of adverse selection requires controlling for market ...
Risk sharing, inequality, and fertility
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 ...
Screening and adverse selection in frictional markets
We incorporate a search-theoretic model of imperfect competition into an otherwise standard model of asymmetric information with unrestricted contracts. We develop a methodology that allows for a sharp analytical characterization of the unique equilibrium and then use this characterization to explore the interaction between adverse selection, screening, and imperfect competition. On the positive side, we show how the structure of equilibrium contracts?and, hence, the relationship between an agent?s type, the quantity he trades, and the corresponding price?is jointly determined by the severity ...
