Plant shutdowns shape industry productivity, the dynamics of employment, and industrial restructuring. Plant closures account for more than half of gross job destruction in U.S. manufacturing. This paper examines the effects of firm structure on U.S. manufacturing plant closures. Plants belonging to multiplant firms and those owned by U.S. multinationals are less likely to exit. However, the superior survival chances are due to the characteristics of the plants rather than the nature of the firms. Controlling for plant and industry attributes, we find that plants owned by multiunit firms and U.S. multinationals are much more likely to close.

This paper examines the factors that increase the probability of entry into exporting. 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 the export market by U.S. plants is substantial, past exporters are apt to reenter, and plants are likely to export in consecutive years. However, we find that entry costs are significant and spillovers from the export activity of other plants are negligible. State export promotion expenditures have no significant effect on the probability of exporting. Plant characteristics, especially those indicative of past success, strongly increase the probability of exporting, as does changing industries.

In this paper, we test whether aggregate productivity movements, especially convergence, are also reflected at the industry level.Using a new result on the asymptotic normality of panel unit root estimators, we find evidence for convergence in total factor productivity for sectors such as services and construction in 14 OECD countries from 1970-1987.However, surprisingly, we find that convergence does not hold for the manufacturing sector.Convergence in total industry occurs as a result of the declining share of manufacturing and the growing share of sevices in these countries.

This paper develops a multicountry model of international trade that provides a simple microfoundation for buyer-seller relationships in trade. We explore a rich data set that identifies buyers and sellers in trade and establish a set of basic facts that guide the development of the theoretical model. We use predictions of the model to examine the role of buyer heterogeneity in a market for firm-level adjustments to trade shocks, as well as to quantitatively evaluate how firms’ marginal costs depend on access to suppliers in foreign markets.

This paper examines determinants of Olympic success at the country level. Does the United States win its fair share of Olympic medals? Why does China win only 6% of the medals even though it has one-fifth of the world's population? We consider the role of population and economic resources in determining medal totals from 1960 to 1996. At the margin, population and income per capita have similar effects, suggesting that both a large population and high per capita GDP are needed to generate high medal totals. We also provide out-of-sample predictions for the 2000 Olympics in Sydney.

This paper examines the factors that give rise to intermediaries in exporting and explores the implications for trade volumes. Export intermediaries such as wholesalers serve different markets and export different products than manufacturing exporters do. Wholesalers are more prevalent in markets with higher destination-specific fixed costs and focus on products that are less differentiated, have lower contract intensity, and have large sunk entry costs. Aggregate exports to destinations with high shares of indirect exports are less responsive to changes in the real exchange rate than are exports to markets served primarily by direct exporters.
