Inter-firm competition has received much attention in the theoretical literature, but recent empirical work suggests that the growth rates of rival firms are uncorrelated, and that firm growth can be taken as an essentially independent process. We begin by investigating the correlations of the...

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 and...

Complicated neoclassical models predict that if investment is sensitive to current financial performance, this is a sign that something is "wrong" and is to be regarded as a problem for policy. Evolutionary theory, on the other hand, refers to the principle of "growth of the fitter" to explain...

A robust feature of the corporate growth process is the exponential distribution of firm growth rates. This striking empirical regularity has been found to hold for a number of different datasets and at different levels of aggregation. In this paper, we propose a simple theoretical model capable...

This paper is an empirical test of the hypothesis that the appropriateness of different business strategies is conditional on the firms distance to the industry frontier. We use data on four 2-digit high-tech manufacturing industries in the US over the period 1972-1999, and apply semi-parametric...

We relate innovation to sales growth for incumbent firms in four high-tech sectors. A firm, on average, experiences only modest growth and may grow for a number of reasons that may or may not be related to ‘innovativeness’. However, given that firms are heterogeneous and that growth rates...

We report several characteristics of industrial dynamics, including the firm size distribution, Gibrat's Law, and also the distribution of growth rates and their autocorrelation. We use a variety of econometric techniques, looking first at the aggregate and subsequently at a sectoral level. Many...

This paper links new firm survival with growth, with a focus on the patterns in firms' growth paths. We theorise a Gambler's Ruin framework by arguing that new rm performance is best modelled as a random walk process, but that survival is nonrandom and depends primarily on the stock of...

In this short research note we investigate the role of diversification in the firm growth process. We build on Penrose’s (1959) Theory of the Growth of the Firm to formulate hypotheses about growth of employment, assets, and sales in the years before, during and after a new product...

Despite an almost universally accepted belief outside academia that entrepreneurial activity is a positive driving force in the economy, the accumulated evidence remains largely inconclusive. The paper positions the increased interest in entrepreneurship since the 1980s within its historical...
