The opacity of over-the-counter (OTC) markets, in which a large number of financial products including credit derivatives trade, appears to have played a central role in the nancial crisis in 2007-09. We model such opacity of OTC markets in a general equilibrium setup where agents share risks,...

We use a model a la Bewly-Huggett-Ayagari to explore the effects of a credit crunch on consumer spending. Households borrow and lend to smooth idiosyncratic income shocks facing an exogenous borrowing constraint. We look at the economy response after an unexpected permananent tightening of this...

Firms commonly spread out their debt expirations across time to reduce the liquidity risk generated by large quantities of debt expiring at the same time. By doing so, they introduce a dynamic coordination problem. In deciding whether to rollover his debt, each maturing creditor is concerned...

We first study export dynamics in a number of large devaluation episodes in emerging markets. Using plant level data, we document that exports expand gradually following a large devaluation primarily because the number of exporters expands gradually. We further show the strong negative...

Preliminary results show that when this model is parameterized to match a number of targets - in particular the joint cross-sectional distribution of liquid and illiquid wealth - it is able to generate responses to fiscal stimulus payments of the observed order of magnitude. The model is also...

Sorting, Employment and Wages in multi-worker firms

This paper analyzes a business cycle model with labor market frictions as well as an extensive labor supply margin. There are exogenous aggregate shocks to productivity, the job finding rate, and the separation rate. Workers also face idiosyncratic productivity (wage) shocks that they cannot...

We use a search model of the labor market in which jobs are characterized by flexibility (such as the possibility of working from home, or discretion in choosing work-hours) to estimate the distribution of preferences over flexibility. In an hedonic wage model, a job amenity is estimated to...

We present a general equilibrium model to understand the implications of short-term debt playing a special role in an economy in providing liquidity and facilitating transactions. In our model the supplies of short-term public and private debt are an endogenous outcome of optimal actions by the...

We study the costs and benefits of Medicaid in a model in which retired single people optimally choose consumption, medical spending and saving, while facing uncertainty about their health, lifespan and medical needs. We document Medicaid take-up rates by age, permanent income, and gender in the...
