This paper studies the effectiveness of collusion in the DRAM cartel. Like other high technology products, DRAM is characterized by learning-by-doing and multiproduct competition. I hypothesize that collusion is more difficult to sustain on a new generation, where learning is high, than an old...

The European Commission years ago adopted a policy of encouraging the substitution of motor carrier haulage of freight with rail and water carrier haulage, as part of its "green" agenda of reducing fuel consumption, emission of pollutants, carbon intensity, and road congestion. Regarding railway...

Starting with the pioneering work of Azar, Schmalz, and Tecu (2018), a rapidly growing body of empirical evidence on the effect of common ownership on market outcomes has emerged. However, testing the robustness of these results to alternative methods and data sources is just beginning. In this...

Monopolists selling complementary products charge a higher price in a static equilibrium than a single multiproduct monopolist would, reducing both the industry profits and consumer surplus. However, firms could instead reach a Pareto improvement by lowering prices to the single monopolist...
