This paper provides a systematic analysis of the welfare effects of vertical integration by a monopolistic input supplier into a monopolistically competitive downstream industry. We give sufficient conditions on consumer preferences that lead to Pareto improving vertical integration. We...

We find the Nash equilibria for monotone n-player symmetric games where each player chooses whether to participate. Examples include market entry games, coordination games, and the bar-room game depicted in the movie 'A Beautiful Mind'. The symmetric Nash equilibrium involves excessive...

This paper provides evidence that incumbents' access to group deep pockets has a negative impact on entry in product markets. Relying on a unique French data set on business groups, the paper presents three major findings. First, consistent with theoretical predictions, the amount of financial...

Europe has taken the global lead in the issuance of third generation (3G) licences for mobile telecommunications according to the UMTS/IMT-2000 family of standards. We survey the recent European UMTS licence auctions and compare their outcomes with the predictions of a simple auction model that...

We investigate how bank competition affects the efficiency of credit allocation, using a model of spatial competition. Our analysis shows that bad loans are more likely the larger the number of banks competing for customers. We study further how many banks will be active if market entry is not...

Stimulating entrepreneurship is high on the policy agenda of many countries. We study the effects of tax policies on entrepreneurs’ choice of riskiness (quality) of an innovation project, and on their mode of commercializing the innovation (market entry versus sale). Limited loss offset...

We argue that firms’ balance sheets were instrumental in the propagation of shocks during the Great Recession. Using establishment-level data, we show that firms that tightened their debt capacity in the run-up (“high-leverage firms”) exhibit a significantly larger decline in employment in...

Germany experienced an even deeper fall in GDP in the Great Recession than the United States, with little employment loss. Employers’ reticence to hire in the preceding expansion, associated in part with a lack of confidence it would last, contributed to an employment shortfall equivalent to...
