This paper empirically investigates the possible market power effects of vertical integration proposed in the theoretical literature on vertical foreclosure. It uses a rich data set of cement and ready-mixed concrete plants that spans several decades to perform a detailed case study. There is...

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...

We examine the bidding behavior of firms competing on ERCOT, the hourly electricity balancing market in Texas. We characterize an equilibrium model of bidding into this uniform-price divisible-good auction market. Using detailed firm-level data on bids and marginal costs of generation, we find...

The modern multiunit enterprise has been touted by historians and economic historians as a major and important phase of organizational change and a significant source of growth. However, no systematic record of the prevalence and patterns of multiunit activity has yet been established. This...

Previous empirical studies that have examined the links between pharmaceutical price controls, profits, cash flows, and investment in research and development (R&D) have been largely based on retrospective statistical analyses of firm- and/or industry-level data. These studies, which have...

Past research has documented that learning by doing-productivity improvements that occur in concert with production increases-is one source of such...

This paper examines how international flows of technological knowledge affect economic performance across industries and firms in different countries. Motivated by the large share of the world's technology investments made by firms that are active across borders, we focus on international trade...

Prior work suggests that more valuable patents are cited more and this view has become standard in the empirical innovation literature. Using an NPE-derived dataset with patent-specific revenues we find that the relationship of citations to value in fact forms an inverted-U, with fewer citations...
