We use a large dataset of approximately 1500 physicists employed by the Centre National de la Recherche Scientifique (CNRS) in France to investigate the role of cumulative advantage in their publication career. Measuring output by time series of the number of publications and the number of...

This paper is a contribution to the small but growing literature that compares the investment and R&D behavior of manufacturing firms in large developed countries that have varying financial and capital market institutions. Specifically, we look at two similar samples of French and United States...

Our two related goals in this paper are the following: Firstly and mainly, we want to examine the effects of major changes in modelling strategy and econometric methodology, over the past twenty years, on estimation of firm-level investment equations using panel data. Secondly, we try to assess...

A comparative study of the contribution of R&D to firm-level productivity in French and United States manufacturing firms in the 1980s is presented. The study uses two large panels of approximately 1000 manufacturing firms covering over half of all R&D spending in each country and focuses on the...

This paper uses a newly available dataset on the R&D performance of individual French manufacturing firms for the 1980s to replicate and update a series of studies on French R&D and productivity growth at the firm level during the 1970s. The focus of the paper is on the use of a single dataset...

We review the econometric literature on measuring the returns to R&D. The theoretical frameworks that have been used are outlined, followed by an extensive discussion of measurement and econometric issues that arise when estimating the models. We then provide a series of tables summarizing the...

Innovation in SMEs exhibits some peculiar features that most traditional indicators of innovation activity do not capture. Therefore, in this paper, we develop a structural model of innovation which incorporates information on innovation success from firm surveys along with the usual R&D...

Italian manufacturing firms have been losing ground with respect to many of their European competitors. This paper presents some empirical evidence on the effects of innovation on employment growth and therefore on firms' productivity with the goal of understanding the roots of such poor...

This introduction to a special issue of EINT surveys a collection of ten papers that study various aspects of innovation and knowledge management and their impact on performance at the firm level for a number of countries. These studies have been conducted using data drawn from innovation...

The identification of age, cohort (vintage), and period (year) effects in a panel of individuals or other units is an old problem in the social sciences, but one that has not been much studied in the context of measuring researcher productivity. In the context of a semi-parametric model of...
