An empirical consensus suggests that there are small employment effects of minimum wage increases. This paper argues that these are short-run elasticities. Long-run elasticities, which may differ from short-run elasticities, are policy relevant. This paper develops a dynamic industry equilibrium...

We present a model of long-duration collateralized debt with risk of default. Applied to the housing market, it can match the homeownership rate, the average foreclosure rate, and the lower tail of the distribution of home-equity ratios across homeowners prior to the recent crisis. We stress the...

We study the dynamic general equilibrium of an economy where risk averse shareholders delegate the management of the firm to risk averse managers. The optimal contract has two main components: an incentive component corresponding to a non-traded equity position and a variable "salary" component...

I develop a dynamic model of behavior to analyze juvenile crime. Forward-looking youths consistently decide between crime and legal activities depending on their endowment of work- and crime-specific human capital, which in turn is shaped by their history of past choices. The model explicitly...

study the efficiency of search equilibrium under decreasing returns to labor in production. Firms can sign long-term contracts with their workers which give them incentives to maximize the joint surplus associated with their relationship. When the firm hires a new worker, the terms of the...

In many search models of the labor market, unemployment insurance (UI) is conveniently interpreted as the value of leisure or home production and is, therefore, treated as a parameter. However, in reality, UI has to be funded through taxation that might be distortionary. In this paper, I analyze...

In this study, we explore the effects of a change in unskilled labor in China on the direction of innovation in the US by incorporating production offshoring into a North-South model of directed technical change. We find that intellectual property rights (IPRs) and offshoring are different ways...

We consider the extent to which cross-country differences in the intergenerational persistence of income can be explained by differences in government spending on early childhood education. We build a life-cycle model where human capital is accumulated in early, middle and late childhood. Both...

When faced with a speculative attack, banks and governments often hesitate, attempting to withstand the attack but giving up after some time, suggesting they have some ex-ante uncertainty about the attack they will face. I model that uncertainty as arising from incomplete information about...

We study the welfare implications of uncertainty in business cycle models. In the modern business cycle literature, multiplicative real shocks to production and/or preferences play an important role as the impulses that produce aggregate fluctuations. Introducing shocks in this way has the...
