How important are financial and labor market frictions for the business cycle dynamics of a small open economy? What are the quantitative effects of increased financial risk on output and inflation? What drives the variation in the intensive and extensive margin of labor supply? What are the...

We examine the setting of national competition policy in a two-country setting,emphasizing the relationship of trade to the goals of competition policy (suchas the degree and nature of competition). The issues we address involve thegeneral equilibrium distributional effects of competition...

Geographical economics analyzes the endogenous determination of the location of economic activity in a general equilibrium framework. We investigate the impact of pollution by focusing on the interaction between location advantages and negative pollution externalities associated with local...
