We use variation in wind speeds at surfing locations in Switzerland as exogenous shifters of users' propensity to post content about their surfing activity onto an online social network. We exploit this variation to test whether users' social ties on the network have a causal effect on their...

This paper proposes methods for identifying indirect network effects with dynamically optimizing consumers purchasing a durable hardware good and associated software. We apply this model to data drawn from the DVD player and titles markets. We observe model-level prices, sales and...

This paper presents new evidence on tradeinduced automation in manufacturing firms using unique data combining a retrospective survey that we have assembled with register data for 2005-2010. In particular, we establish a causal effect where firms that have specialized in product types for which...

In view of the uncertainty over the ability of merging firms to achieve efficiency gains, we model the post-merger situation as a Cournot oligopoly wherein the outsiders face uncertainty about the merged entity's final cost. At the Bayesian equilibrium, a bilateral merger is profitable provided...

This paper examines the importance of indirect network effects in the U.S. video game market between 1994 and 2002. The diffusion of game systems is analyzed by the interaction between console adoption decisions and software supply decisions. Estimation results suggest that introductory pricing...

This paper surveys four Argentinean industries light ships, television programs, wines, and wooden furniture that have experienced substantial export growth in recent years, particularly to developed countries. The case studies first describe the structure of the industries, then characterize...

In a world where corporate boards are not required by law, I identify a governance and a distribute motive for board establishment and board composition. I investigate the presence of these motives in a sample of 23.000+ closely held corporations. Board frequency increases with more owners, if...

This study empirically investigates if competition’s impact on firm performance depends on the ownership structure. Our results show that an increase in import competition has a positive effect on firms with concentrated ownership and a negative effect on firms with dispersed ownership,...

This paper investigates the determinants of vertical integration. We first derive a number of predictions regarding the relationship between technology intensity and vertical integration from a simple model with nancial imperfections andincomplete contracts. Then, we investigate these...

Using a general two-stage framework, this paper gives sufficient conditions for increasing competition to have negative or positive effects on R&D-investment, respectively. Both possibilities arise in plausible situations, even if one uses relatively narrow definitions of increasing competition....
