We study general equilibrium with nonconvexities. In these economies there exist sunspot equilibria without the usual assumptions needed in convex economies, and they have good welfare properties. Moreover, in these equilibria, agents act as if they have quasi-linear utility. Hence wealth...

The same policies or technological changes that affect the labor market can also affect the extent of criminal activities. For instance, while an increase in unemployment benefits can raise unemployment duration it may also reduce crimes by unemployed. Or, a technological change in the home...

We study economies with an essential role for liquid assets in transactions. The model can generate multiple stationary equilibria, across which asset prices, market participation, capitalization, output and welfare are positively related. It can also generate a variety of nonstationary...

In this paper we investigate the effects of government budget deficit restrictions in a finite horizon model with imperfect consumer credit market. When financial markets are perfect anonymous lump-sum taxes are sufficient to achieve irrelevance of government budget deficit restrictions in the...

Property crime is today more widespread in Europe than in the United States, while the opposite was true during the 1970s and 1980s. In this paper we study the determinants of crime in a dynamic general equilibrium model with uninsured idiosyncratic shocks. We focus on Germany, and compute the...

This paper takes a slightly different approach and uses data from labor market flows to evaluate labor market dynamics during the time period in which unemployment benefits were extended by statute, July 2008 to May 2012. To do so, we develop a simple search model to study labor market dynamics....

Over the U.S. business cycle, fluctuations in residential investment systematically lead fluctuations in real GDP. Evidently, these dynamics are specific to the U.S. and Canada. In other developed economies residential investment tends to be coincident with the cycle. On the other hand, in all...

This paper consists of two parts. In the first part we use the PSID (which is now long enough to allow the observation of the entire working life) to document empirical life cycle profiles (wage, earnings, hours) of a cohort of workers followed from when they enter the labor market in 1967 to...

We then consider a model that extends Cardia and Ng (2006) analysis of grandparenting and rationalizes this evidence with standard preferences and working-age grandparents. The key idea is that individuals value a particular good, "time spent with family children". This good can be "produced"...
