We present evidence that event studies can help antitrust agencies forecast impacts of mergers on innovation. In large pharmaceutical mergers, cumulative abnormal returns on portfolios of rivals predict post-merger changes in the combined firm's R&D intensity. More favorable impacts on rivals...

We use a simple model of collaborative innovation to structure an empirical analysis of minority equity links in biotechnology alliances between clients and Ramp;D firms. In the model, an equity link is an investment in information acquisition: it improves the ability of the client to learn...

Antitrust enforcement makes it difficult to test theories of cartel formation because most attempts to form cartels are blocked. However, federal laws allow U.S. produce growers to operate marketing cartels through devices called marketing orders. These cartels use quantity controls and quality...

This paper uses a stationary multivariate asymmetric GARCH specification of the international capital asset pricing model to investigate contagion effects across six developed and emerging East Asian markets as well as the US and the World markets around the time of the Asian currency crisis of...

This paper estimates quality and cost innovations in the early automobile, personal computer, rigid disk drive, computer monitor, and computer printer industries using industry-level data on firm numbers, price, quantity, and quality and an equilibrium model of industry evolution. The results...

Previous work on exit in declining industries has neglected mergers. We examine a simple model that predicts which declining industries experience horizontal mergers. Mergers are more likely if 1) market concentration is high; 2) the inverse demand curve is steep at high levels of output and...
