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...

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,...

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...

The theme of these notes, in general, is the population dynamics of evolutionaryprocesses, and, in particular, a number of accounting concepts that are central to anyunderstanding of processes of evolution of the variation and selective retention kind.The accounting concepts I use are naturally...

Schumpeterian development is characterised by the simultaneous interplay of growthand qualitative transformations of the economic system. At the sectoral level, suchqualitative transformations become manifest as variations in the sectoral composition ofproduction. Following the implementation of...

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...

This paper proposes to identify the micro-level sources for the dy-namic increasing returns occurring at an aggregate level. The paperreverts to a micro model of technological change in-line with the evolu-tionary literature on industrial dynamics. The data generated throughnumerical simulations...

This paper agrees that a suitably generalized Darwinism may help understandsocioeconomic change, but finds the most publicized generalization by Hodgson and Knudsenunsuitable. To do better, it generalizes the extension of Neo-Darwinism into evolutionarydevelopmental biology (“evo-devo”),...
