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

The dynamics of drug launch has been an under-researched area. Most of the studies in this field focus on developed countries, quite uniform in terms of disease profile and regulatory framework, and analyse whether stringency in regulation influences launch delay. Developing countries, in...

The paper unravels the subversive nature of Schumpeter’s proposition that entrepreneurs carry out innovations (the micro level), that swarms of followers imitate them (meso) and that, as a consequence, 'creative destruction’ leads to economic development 'from within’...

We focus on the relationship of age and diversification patterns of German machine tool manufacturers in the post war era. Based on trade journals we track the entire firm populations' product portfolio development throughout each firm's lifetime. We distinguish between 'minor diversification'...

While several plots of the aggregate age distribution suggest that firm age is exponentially distributed, we find some departures from the exponential benchmark. At the lower tail, we find that very young establishments are more numerous than expected, but they face high exit hazards. At the...

The adequate role of Darwinist concepts in evolutionary economics has long been a contentious issue. The controversy has recently been rekindled and modified by the position of "Universal Darwinism", most prominently favored by Geoffrey Hodgson and Thorbjørn Knudsen. They argue that the...

On the basis of the technical definition of selection developed by George Price (1995), we describe two forms of selection that commonly occur at the social level, subset selection and generative selection. Both forms of selection are abstract and general, and therefore also incomplete; both...

We attempt to describe the coevolution of employment growth, sales growth and growth of profits in a panel of French manufacturing firms 1996-2004. Our analysis entails ‘recursive’ panel vector autoregressions, whereby we impose the structure of employment growth leading to contemporaneous...

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

This study investigates the usefulness of exponential random graph models (ERGM) to analyze the determinants of cross-regional R and D collaboration networks. Using spatial interaction models, most research on R and D collaboration between regions is constrained to focus on determinants at the...
