Despite lower incomes, the self-employed consistently report higher satisfaction with theirjobs. But are self-employed individuals also happier, more satised with their lives as awhole? High job satisfaction might cause them to neglect other important domains of life,such that the fullling job...

Inter-rm competition has received much attention in the theoreticalliterature, but recent empirical work suggests that the growth rates of ri-val rms are uncorrelated, and that rm growth can be taken as an essen-tially independent process. We begin by investigating the correlations of thegrowth...

Our empirical literature review shows that little is known about how firm performance changes withage, presumably because of the paucity of data on firm age. For Spanish manufacturing firms, weanalyse the firm performance related to firm age between 1998 and 2006. We find evidence thatfirms...

The theoretical literature identifies three important entrepreneurial dimensions,namely discovering new opportunities, responsiveness to uncertainty, and coordination of a firm.In the empirical literature, past experience has been identified as having an important influenceon organizational...

Necessity spin-offs are organized by employees of incumbent firms to escape deterioratingjob conditions. This paper proposes a conceptual model of the spin-off process. Necessityspin-offs are distinguished from opportunity spin-offs on the basis of their triggering events.An empirical analysis...

We apply a panel vector autoregression model to a firm-level longitudinal databaseto observe the co-evolution of sales growth, employment growth, profits growth andgrowth of R&D expenditure. Contrary to expectations, profit growth seems to havelittle detectable effect on R&D investment. Instead,...

Based on new data, this paper studies invention disclosure, licensing, and firm formationactivities of Max Planck Institute directors over the time period 1985-2004, and analyzestheir effects on scientists’ publication and citation records. The results are consistent withprior findings that...

The objective of this paper is to relate entrepreneurship to a theory of the humanmind, setting both within an evolutionary perspective. The first requirement,therefore, is to indicate what this perspective implies. As a generic concept, I takeevolution to be the self-transformation of a system...

We use new data on the location and background of entrants into the U.S. tireindustry to analyze the factors that caused the industry to be so regionally concentratedaround Akron, Ohio, a small city with no particular advantages for tire production. Weanalyze the states where firms entered and...

During its early and formative years, the U.S. tire industry was heavily concentratedaround Akron, Ohio. We test the extent to which entrants in Ohio were attracted to theAkron area by agglomeration benefits, contributing to a self-reinforcing processenvisioned in many modern theories of...
