This paper examines the frequency, pervasiveness, and determinants of product switching by US manufacturing firms. We find that one-half of firms alter their mix of five-digit SIC products every five years, that product switching is correlated with both firm- and firm-product attributes, and...

This paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by U.S. manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than...

This paper examines the decision to enter the export market by German firms. While exports have played an important role in recent German business cycle movements, little is known about the export supply response of German firms. This paper presents a dynamic model of the export decision by a...

A growing body of empirical work has documented the superior performance characteristics" of exporting plants and firms relative to non-exporters. Employment, shipments and capital intensity are all higher at exporters at any given moment. This paper asks whether good" firms become exporters or...

We explore the relation between the establishment of a regulatory agency and the performance of the electricity sector. We exploit a dataset comprising firmlevel information on a representative sample of 220 electric utilities from 51 development countries for the period 1985 to 2005. Our...

Limited competition has been a serious concern in infrastructure procurement. Importantly, however, there are normally a number of potential bidders initially showing interest in proposed projects. This paper focuses on tackling the question why these initially interested bidders fade out. An...

Firms' decisions about which goods to produce are often made at a more disaggregate level than the data observed by empirical researchers. When products differ according to production technique or the way in which they enter demand, this data aggregation problem introduces a bias into standard...

This paper examines the frequency, pervasiveness and determinants of product switching among U.S. manufacturing firms. We find that two-thirds of firms alter their mix of five-digit SIC products every five years, that one-third of the increase in real U.S. manufacturing shipments between 1972...

This paper presents a dynamic model of the export decision by a profit-maximizing firm. Using a panel of U.S. manufacturing plants, we test for the role of plant characteristics, spillovers from neighboring exporters, entry costs and government export promotion expenditures. Entry and exit in...
