Why are financial crises associated with a sustained rise in unemployment? We develop a tractable model with frictions in both credit and labor markets to study the aggregate andmicro-level implications of a credit crunch---i.e., a sudden tightening of collateral constraints. When we simulate a...

Market failures provide a rationale for policy intervention. But policies are often hard to alter once in place. We argue that this inertia can result in well-intended policies having sizable negative long-run effects on aggregate output and productivity. In our theory, financial frictions...

We study the effect of alternative monetary policies during a credit crunch, modeled as a shock to collateral constraints. We consider a model with entrepreneurs that are heterogeneous in their productivity and net worth, face collateral constraints that limit their investment, and whose...

This paper quanties the role that increases in the demand for skill intensive goods and services, the ecient scale of production of services, and female labor supply have in explaining the growth of services. We extend the model in Buera and Kaboski (2012a,b) to a two-person household model,...

This paper examines the role of the market for high-skilled labor in explaining variation in the levels and dynamics of the service share, home production time, and market labor across countries. We establish and extend key facts for a cross-section of countries. First, growth in the total share...

We provide a tractable theory of innovation and diffusion of technologies to explore the role of international trade and foreign direct investment (FDI). We model innovation and diffusion as a process involving the combination of new ideas with insights from other industries or countries. We...

We study the evolution of trade policies over time and across countries. We consider a model in which own and neighbors' past experiences influence policy choices, through their effect on policymakers' beliefs. We estimate the model using a large panel of countries. We find that there is a...

We develop a model of retirement and human capital investment to study the effects of tax and retirement policies. Workers choose the supply of raw labor (career length) and also the human capital embodied in their labor. Our model explains a significant fraction of the US-Europe difference in...

We develop a model that accounts for several stylized facts about immigrant earnings. First, it implies that new immigrants learn less than natives with the same level of schooling. Second, depending on the age of immigration, it implies that initially, immigrant earnings need not grow faster...

We study human capital investment decisions in the face of risk. Human capital is an important source of uninsurable idiosyncratic risk. However, the few studies that focus on the effect of risk on human capital investment typically treat human capital like any other risky asset, without taking...
