The simplest tests of capital market efficiency are tests of the fair game model: conditional expected returns less the interest rate are equal to zero. The fair game model is thought to obtain only when markets are perfectly liquid. We show that this conjecture is false. In a model of the...

The current scale of mortgage delinquencies and foreclosures - particularly in the subprime market - has sparked a renewed debate over the Community Reinvestment Act (CRA) and the regulations governing home mortgage lending. On one side, detractors argue that the CRA helped to precipitate the...

We develop a two-sector search-matching model of the labor market with imperfect mobility of workers, augmented to incorporate a housing market and a frictional goods market. Homeowners use home equity as collateral to finance idiosyncratic consumption opportunities. A financial innovation that...

The standard argument for abstracting from capital accumulation in sticky-price macro models is based on their short-run focus: over this horizon, capital does not move much. This argument is more problematic in the context of real exchange rate (RER) dynamics, which are very persistent. In this...

I introduce a method that combines data from the U.S. Current Population Survey, Job Openings and Labor Turnover Survey, and state-level Job Vacancy Surveys to construct annual estimates of the number of job openings in the U.S. in the Spring by industry and occupation. I present these estimates...

Progress on the question of whether policymakers should respond directly to financial variables requires a realistic economic model that captures the links between asset prices, credit expansion, and real economic activity. Standard DSGE models with fully-rational expectations have difficulty...

We study the macroeconomic effects of uncertainty shocks in a DSGE model with labor search frictions and sticky prices. In contrast to a real business cycle model, the model with search frictions implies that uncertainty shocks reduce potential output, because a job match represents a long-term...
