In this study we derive a structural econometric model of learning by doing with multiproduct competition from a dynamic oligopoly game. We show the importance to account for multiproduction effects through product differentiation when measuring learning by doing. Using quarterly firm-level data...

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...

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...

Firms’ decisions about which goods to produce are often made at a more disaggregate level than the data observed by empirical researchers. When products differ according to production technique or the way in which they enter demand, this data aggregation problem introduces a bias into standard...

In most transition countries the aggregate level evidence suggests that most industries are just destroying jobs, due to the legacy of communism where over-manning levels of employment were the norm. This Paper sheds light on whether the transition process in Slovenian manufacturing has been one...

This paper examines the frequency, pervasiveness and determinants of product switching among U.S. manufacturing firms. We find that two-thirds of firms alter their mix of five-digit SIC products every five years, that one-third of the increase in real U.S. manufacturing shipments between 1972...

This Paper develops a model of endogenous product selection by firms. The theory is motivated by new evidence we present on the importance of product switching by US manufacturers. Two-thirds of continuing firms change their product mix every five years, and product switches involve more than...

How does firm entry affect innovation incentives and productivity growth in incumbent firms? Micro-data suggests that there is heterogeneity across industries - incumbents in technologically advanced industries react positively to entry, but not in laggard industries. To explain this pattern, we...

Using data from a large enterprise-level panel designed to address this issue, we account for enterprise performance in Russia. We link performance to four aspects of the economic environment outlined in the literature: enterprise ownership; corporate governance; market structures and competition;...

Using standard as well as recently developed univariate and bivariate count data models, this paper analyses the determinants of workplace accidents using a firm data set for Germany. Given the tight system of public workplace safety regulation, introduced partly as early as in 1869 and the...
