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...

In this paper, we examine the inconclusive debate on regulatory competition in Europe. We demonstrate that the recent expansion in the EU company law has created archetypal underpinning for formation of regulatory competition: the ground-breaking "triptych" of the ECJ on Centros, Überseering,...

This paper contributes to the relatively new literature on the role of intermediaries in international trade. Using Italian firm-level data, we document significant differences between exporters of different types and highlight the role of country-specific fixed cost in the choice of direct...

The paper investigates the effects of Mergers and Acquisitions (M&A) on corporate research and development (R&D) strategies using Community Innovation Survey (CIS) data on the Dutch manufacturing sector. The focus of the research is whether M&A affect corporate innovation strategies, favouring...

This paper investigates the relation between firms' productivity and exporting behavior in presence of export intermediaries.
