We draw attention to the role of economic geography in explaining important cross-sectional facts which are difficult to account for in existing models of industrialization. By construction, closed-economy models that stress the role of local demand in generating sufficient expenditure on...

This paper presents novel empirical evidence on key predictions of heterogeneous firm models by examining stock market reactions to the Canada-United States Free Trade Agreement of 1989 (CUSFTA). Using the uncertainty surrounding the agreement's ratification, I show that the pattern of abnormal...
