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...

We estimate a structural model of heterogeneous multiproduct firms to examine the sources of firm heterogeneity emphasized in the recent trade and macro literatures. Using Nielsen barcode data on prices and sales, we estimate elasticities of substitution within and between firms, and use the...

This paper examines the longevity of entrants. We find size to be an important determinant of the chances of survival, this being particularly relevant to de novo entrants as compared to entry by established firms. Current size is also found to be a better predictor of failure than initial size....

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...

A growing body of literature shows that geographic location plays an important role in influencing economic phenomena. Despite the renewed interest in economic geography, the existing literature on the firm size distribution (FSD) has ignored the impact of geographic location. A wave of recent...

Reduced form approaches to estimate markups typically exploit variation in observed input and output. However, these approaches ignore the presence of fixed input factors, which may result in an overestimation of the price-cost margins. We first propose a new methodology to simultaneously...

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 examines the effects of two faces of R&D (innovation and development of absorptive or learning capacity) and technology spillovers from FDI (foreign direct investment) on a firm’s productivity growth. Using firm-level panel data on Czech manufacturing firms between 1995 and 1998, I...

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...

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...
