The production of copyrighted materials varies widely across countries, and how it evolves over time has important policy implications. I propose a simple dynamic model of copyrights and the public domain, which predicts conditional convergence of per capita copyright production among countries....

Copyright levies are used as a way of compensating rightholders for the private use made of their protected works. This paper builds a simple model of copyright levies and investigates welfare implications of the harmonization of levy rates. The result is that, when the policy-maker places...

The demand for electronic books (e-books) and the e-book readers are complementary. On the one hand, the emergence of e-book readers such as Amazon's Kindle has triggered the recent growth of the e-book market. On the other hand, several issues in the e-book market can affect the future of the...

Using a panel data of S&P 500 Index firms covering 1998-2004, this paper compares the determinants of lobbying expenditures and campaign contributions and estimates the returns to lobbying as assessed by the financial market. Lobbying depends more on managerial incentives and protection needs...

This paper studies the determinants of lobbying-employment decisions of former members of the U.S. House of Representatives for the 105th–108th Congresses. The main empirical findings indicate that there are two groups more likely to become lobbyists: members not re-elected who had more...

This article shows that competition is inversely related to the strength of evolutionary dynamics using a collegiate university's admission statistics during the period 2004--2009. Specifically, estimated coefficients of the replicator dynamic equation is inversely related to the subject's...

This study investigates the structure of optimal incentives in a stochastic environment and provides evidence for the use of self-enforcing relational contracts. We show theoretically that under relational contracting, firms can credibly promise chief executive officers (CEOs) larger bonuses in...

type="main" <p>We study a model in which firms offer financial products to individuals, post prices for their products, and screen consumers who apply to purchase them. Any information obtained in the screening process may be traded to another firm selling related products. We show that firms'...</p>

We present theoretical and empirical analyses of indirect network effects for a hardware market with vertically differentiated complementary goods. We demonstrate that the heretofore typical use of aggregate software counts can mis-measure the presence and/or magnitude of indirect network...
