This paper investigates the relation between changes in self-employment and changes in unemployment at the regional level in Spain in the period 1979-2001. We estimate a vector autoregression model as proposed by Audretsch, Carree, van Stel and Thurik (2005) using a data base for Spanish...

We experimentally investigate competition in innovation in a patent race scenario. Pairs of subjects compete as seller firms on a duopoly market, engaging in risky search investments. Successful innovation is rewarded through temporary monopoly rents. Throughout the interaction, subjects receive...

This paper examines to what extent recent empirical evidence can collectively and systematically substantiate the claim that entrepreneurship has important economic value. Hence, a systematic review is provided that answers the question: What is the contribution of entrepreneurs to the economy...

This paper analyses the effects of innovation networks on product and process innovation and sales growth of high technology SMEs. Innovation net- works are positively related to both product and process innovation, i.e. knowledge creation. One exception is the negative effect of innovation...

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...

This paper empirically analyzes the determinants of demand in the German automobile industry. Our primary goal is to refine the existing literature on that topic by exploring the impact of uniqueness seeking behaviour of individuals on the demand schedule. Using a dataset on the segment of...

In his oft-cited "What do we know about entry?", Paul Geroski (1995) gave a survey of empirical works on this central topic regarding industrial organization and, more precisely, market dynamics. Surprisingly, his article remains silent on the spatial dimension of these dynamics. This paper...
