We review and evaluate some recent contributions on the modeling of entrepreneurship within a neoclassical framework, analyzing how and to what extent the fundamental ingredients suggested in the social science literature were captured. We show how these approaches are important in stressing the...

A stylized fact of economic development is the structural transformation of countries from traditional, mainly agricultural societies to modern economies dominated by manufacturing and services. In this paper we provide an endogenous growth model to illuminate the role of entrepreneurial...

In this paper we construct a model in which entrepreneurial innovations are sold into oligopolistic industries and where adverse selection problems between entrepreneurs, venture capitalists and incumbents are present. We show that as exacerbated development by better-informed venture-backed...

This paper takes a different perspective toward the escape entry incentive of incumbent firms to innovate. New entrants spawned from incumbents are not necessarily a threat; they can complement incumbents’ production by commercializing knowledge incumbents are not willing or able to exploit....

We develop a theory of commercialization mode (entry or sale) of entrepreneurial inventions into oligopoly, and show that an invention of higher quality is more likely to be sold (or licensed) to an incumbent due to strategic product market effects on the sales price. Moreover, preemptive...

'Was macht Gründungen aus Arbeitslosigkeit anders?' Um diese Frage zu beantworten, entwickeln wir einen theoretischen Ansatz für die Gründungsaktivität aus Arbeitslosigkeit. Weiterhin schätzen wir räumlich-autoregressive Modelle für die regionalen Gründungsraten aus Arbeitslosigkeit und...

Das Papier untersucht die 'Jack-of-all-Trades'-Hypothese. Diese unterstellt, dass nicht die Höhe der Produktivität eines Individuums ausschlaggebend ist für eine selbständige Aktivität, sondern deren Bandbreite an Fähigkeiten oder Erfahrung (Lazear 2005). Die Analyse konzentriert sich auf...

Cross-sectional tests of the Jack-of-All-Trades theory of entrepreneurship invariably conclude that accumulation of balanced skill-mix across different fields of expertise stimulates entrepreneurship. Yet, none of these considers individual unobservable characteristics which may simultaneously...

We examine the role of spatial proximity for Venture Capital (VC) investments in Germany. The main database is a survey of 85 personal interviews with representatives of different types of financial institutions. The analysis shows that spatial proximity is far less important for VC investments...

Considerable debate surrounds the concept of entrepreneurial opportunities. This paper contributes to the discussion by bringing in concepts and findings from evolutionary economics. It makes three points. First, adopting an evolutionary market process perspective sheds new light on the nature...
