We examine how policy uncertainty affects firm innovation and competitive dynamism. In R&D races, the gap in the rate of innovation, rather than the absolute rate, determines the winner. As a result, periods of depressed innovation and investment from policy uncertainty present an opportune...

We test whether intellectual property rights foster or hinder innovation by estimating IV structural equations for a large sample of Swiss firms. We find that better appropriability conditions at the industry level raise the number of competitors. However, conditional on the given industry...

We test whether intellectual property rights (IPRs) foster or hinder innovation by estimating IV structural equations for a large sample of Swiss firms. We find that better appropriability conditions at the industry level raise the number of competitors. However, conditional on the given...

This paper examines empirically the role of market structure for the influence of spill-over effects on R&D-cooperations. The results of a microeconometric analysis, based on firm data on innovation, let in general presume that with intensified competition also the influence of spillovers on...

Should the FTC have allowed Zillow to acquire its foremost rival, Trulia? It is increasingly well-accepted that digital platforms tend toward dominance in their immediately adjacent relevant-product markets. Google, for example, has long held a majority share of the markets for general-search...

The idea that market selection promotes survival and expansion of the “fittest” producersis a key principle underlying theories of competition. Yet, despite its intuitive appeal, thehypothesis that companies with superior productivity also exhibit higher growth lacks em-pirical support. One...

Using administrative data on U.S. multisector firms, we document a cross-sectoral propagation of the import competition from China (“China shock”) through firms’ internal networks: Employment of an establishment in a given industry is negatively affected by China shock that hits...

This paper derives a three stage Cournot duopoly game for research collaboration, research expenditures and product market competition. The amount of knowledge firms can absorb from other firms is made dependent on their own research efforts, e.g., firms' absorptive capacity is treated as an...

This article analyzes how the perceived effectiveness of intellectual property protection and competitive pressure affect firms' innovation strategy choices, concretely, whether to abstain from innovation, to introduce products that are known in the market but new to the firm (imitation) or to...
