Africa and Latin America secured their independence from European colonial rule a century and half apart: most of Latin America after 1820 and most of Africa after 1960. Despite the distance in time and space, they share important similarities. In each case independence was followed by political...

Recent theoretical work predicts that an important margin of adjustment to deregulation or trade reforms is the reallocation of output within firms through changes in their product mix. Empirical work has accordingly shifted its focus towards multi-product firms and their product mix decisions....

Taking the early U.S. automobile industry as an example, we evaluate four competing hypotheses on regional industry agglomeration: intra-industry local externalities, inter-industry local externalities, employee spinouts, and location fixed-effects. Our findings suggest that inter-industry...

This chapter reviews academic research on the connections between agglomeration and innovation. We first describe the conceptual distinctions between invention and innovation. We then describe how these factors are frequently measured in the data and some resulting empirical regularities....

We explore how changes in ownership and managerial control affect the productivity and profitability of producers. Using detailed operational, financial, and ownership data from the Japanese cotton spinning industry at the turn of the last century, we find a more nuanced picture than the...

The economic costs of environmental regulations have been widely debated since the U.S. began to restrict pollution emissions more than four decades ago. Using detailed production data from nearly 1.2 million plant observations drawn from the 1972-1993 Annual Survey of Manufactures, we estimate...

Do natural resources benefit producer economies, or is there a "Natural Resource Curse," perhaps as Dutch Disease crowds out manufacturing? We combine new data on oil and gas abundance with Census of Manufactures microdata to estimate how oil and gas booms have affected local economies in the...

In markets where spatial competition is important, many models predict that average prices are lower in denser markets (i.e., those with more producers per unit area). Homogeneous-producer models attribute this effect solely to lower optimal markups. However, when producers instead differ in...

Despite the fact that importing and exporting are extremely rare firm activities, economists generally devote little attention to the role of firms when discussing international trade. This paper summarizes key differences between trading and non-trading firms, demonstrates how these differences...
