This paper is a reflective survey of past and recent econometric work on the growth of firms. Most of this work suggests that firm size follows a random walk; i.e. that corporate growth rates are random. The survey documents this, and shows what a strong result this is by contrasting it with...

The goal of this essay is to bring the work of organizational ecologists on population dynamics to the attention of economists. Following a relatively brief exposition of the basic structure of the arguments made by organizational ecologists, we explore a number of areas where...

Market definitions are an abstraction: they are useful only to the extent that they help us to organize the way we think about certain types of economic activity. This paper critically examines three different methods of identifying market boundaries, stressing the link between substantive...

The literature on new technology diffusion is vast, and it spills over many conventional disciplinary boundaries. This paper surveys this literature by focussing on alternative explanations of the dominant stylized fact in this are: namely, that the usage of new technologies over time typically...

This paper examines some of the determinants of total factor productivity growth using a sample of 216 large UK firms observed over the period 1974–90, and then using three further samples which were used to check the robustness of the results. The main focus of the paper is on identifying the...

This Paper focuses on a single simple stylized fact which stands out from the post-war history of the US Car industry, namely that industry concentration fell just at the same time as industry advertising expenditures rose sharply. Since both events were almost certainly caused by the entry and...

It is widely believed that the implementation of the Single Market Programme in 1992 has had an impact on national markets in Europe, and some people have argued that it has induced a convergence in industrial structures across countries. Using a newly available database, however, covering...

Cross-section or short-panel econometric techniques typically used to examine Gibrat’s Law of Proportionate Effect suggest that some degree of mean reversion exists, but may exaggerate the apparent randomness of corporate growth. We argue that a more natural way to explore the long-run...

This paper examines the innovative history of a number of UK firms using two large databases, looking for evidence consistent with the view that firms who innovate typically do so persistently. The first sample contains 3,304 firms who registered at least one patent in the United States during...

This Paper examines four models that might be used to account for variations in the number of producers who operate in a particular market over the lifetime of that market. Two of these are standard economics textbook models, one is a non-standard model and one is a textbook model derived from...
