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...

Interest in market power has recently surged among economists in many fields, well beyond its traditional home in industrial organization. This has focused empirical attention on markups, the ratios of price to marginal cost in product markets, and markdowns, the ratios of inputs' marginal...

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...

Many firms own links of production chains- i.e., they own both upstream and downstream plants in vertically linked industries. We use broad-based yet detailed data from the economy’s goods-producing sectors to investigate the reasons for such vertical ownership. It does not appear that...

We explore how changes in ownership affect the productivity and profitability of producers. Using detailed data from the Japanese cotton spinning industry at the turn of the last century, we find that acquired firms' production facilities were not on average less physically productive than the...

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...
