We use panel data on digital song and album sales coupled with a quasi-random price experiment to determine own- and cross-price elasticities for songs and albums. We then develop a structural model of consumer demand to estimate welfare under various policy relevant counterfactual scenarios....

This outstanding collection provides a fitting tribute to the diversity and depth of Paul David’s contributions. The papers included range from simulation models of the evolution of market structure in the presence of innovation, through historical investigations of knowledge networks and...

Over the last decade, companies have paid greater attention to the management of their intellectual assets. We build a model that helps understand how licensing activity should be organized within large corporations. More specifically, we compare decentralization—where the business unit using...

Diagnostic information allows an agent to predict the state of nature about the success of an investment project better than the prior. We analyze the optimal pricing scheme for selling diagnostic information to buyers with different, privately known, ex ante success probability. Investment...
