In a general-equilibrium economy with nonconvexities, there are sunspot equilibria with good welfare properties; sunspots can ameliorate the effects of the nonconvexities. For these economies, we show that agents act as if they have quasi-linear utility functions. We use this result to construct...

This paper studies the relationship between the availability of unsecured credit to households and unemployment. We extend the Mortensen-Pissarides model to include a goods market with search and financial frictions. Households, who have limited commitment, face endogenous borrowing constraints...

This paper extends the Pissarides [Pissarides, Christopher A. Equilibrium Unemployment Theory. Cambridge: MIT (2000)] model of the labor market to include crime and punishment à la Becker [Becker, Gary S. "Crime and punishment: an economic approach." Journal of Political Economy 76 (1968):...

The same forces that lead to changes in participation in the labor market can also affect the extent of criminal activity. To analyze such interaction we construct a search-theoretic model where labor market participation, labor market outcomes and crime are determined jointly. The model is...

This study analyzes economies with an essential role for liquid assets in the exchange process. 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...
