Why do firms cluster near one another? We test Marshall's theories of industrial agglomeration by examining which industries locate near one another, or coagglomerate. We construct pairwise coagglomeration indices for US manufacturing industries from the Economic Census. We then relate...

We measure the impact of a drastic new technology for producing steel--the minimill--on industry-wide productivity in the US steel industry, using unique plant-level data between 1963 and 2002. The sharp increase in the industry's productivity is linked to this new technology through two...

We report evidence that Bitnet adoption facilitated increased research collaboration between US universities. However, not all institutions benefited equally. Using panel data from seven top engineering journals, Bitnet connection records, and institution ranking data, we find that middle-tier...

Using European data, this paper finds that (i) industry entry and exit rates are positively related to industry rates of investment-specific technical change (ISTC); and (ii) the sensitivity of industry entry and exit rates to cross-country differences in entry costs depends on industry rates of...

This paper argues that the extent of financial contagion exhibits a form of phase transition: as long as the magnitude of negative shocks affecting financial institutions are sufficiently small, a more densely connected financial network (corresponding to a more diversified pattern of interbank...

We model retail-price recommendations (RPRs) as a communication device in vertical supply relations with private manufacturer information on production costs and consumer demand. With static trade, RPRs are irrelevant, and the equilibrium outcome is inefficient. With repeated trade, RPRs can...

We use broad-based yet detailed data from the economy's goods-producing sectors to investigate firms' ownership of production chains. It does not appear that vertical ownership is primarily used to facilitate transfers of goods along the production chain, as is often presumed: roughly one-half...
