Presentation of some new results showing how, under very general conditions, the recursive saddle-point method, pioneered by Marcet and Marimon, delivers the appropriate solution for contracting problems with intertemporal incentive constraints, with or without unique solutions. These results...

During the last three decades the stock of government debt has increased in most developed countries. During the same period international capital markets have been liberalized. In this paper we develop a two-country political economy model with incomplete markets and endogenous government...

The 2008-2009 US crisis is characterized by an unprecedented degree of international synchronization, as all other G7 countries experienced large contractions. The international synchronization of the recent crisis is not present in many of the previous US contractions. We study a two-country...

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...
