The paper investigates the relationship between human capital diversity measured in terms of occupational diversity and a firm's likelihood to innovate. The empirical analysis is based on a linked employer-employee panel dataset of German firms over the period 1998 to 2007. Despite notable...

The present paper examines one of the central elements of evolutionary thinking - competition formalized by the replicator dynamics mechanism. Using data on product characteristics of automobiles sold on the German domestic market over the period 2001-2006, we construct a competitiveness or...

This survey reviews the theoretical literature on high impact entrepreneurship. The survey is guided in part by the recent classification changes at the Journal of Economic Literature (JEL) regarding entrepreneurship. The board voted to create a new classification code, L26, for...

Empirical analyses show that the employment effects of start-ups are highest in agglomerations, whereas moderately congested areas exhibit only modest effects, and weak or even no significant effects could be found in rural regions. This paper will set out to show that these discrepancies arise...

We present results from a series of experiments that allow us to measure overbidding and, in particular, underbidding in first-price auctions. We investigate how the amount of underbidding depends on seemingly innocent parameters of the experimental setup. To structure our data we present and...

We examine turbulence over the product life cycle using the lowest possible level of industry aggregation, allowing for the use of panel data to study the evolution of single product markets. We find that replacement of exiting firms by subsequent entry plays a primary role in generating...

The average firm size of the top R&D investors among US-based companies is smaller than that of the EU-based firms. Does this help to explain why the US has a greater R&D intensity, or is the higher firm size in the EU, just as its lower R&D intensity, determined by the sectors in which the top...

The key element of models of contest is the Contest Success Function (CSF) which specifies the winning probabilities of agents. We provide an axiomatization of two parametric families of CSF’s. In the first, the winning probability of each agent depends on the investments and a vector of...

The aim of this paper is to test whether patent-based indicators are still reliable measures of innovativeness in light of organizational changes in the field of Intellectual Property Rights (IPR) protection and the regulatory reforms already under way respectively at the U.S. Patent and...
