We estimate the magnitude of spillovers generated by 112 academic "superstars" who died pre- maturely and unexpectedly, thus providing an exogenous source of variation in the structure of their collaborators' coauthorship networks. Following the death of a superstar, we find that collaborators...

The existence of complementarity across management practices has been proposed as one potential explanation for the persistence of firm-level productivity differences. However, thus far no conclusive population-level tests of the complementary joint adoption of management practices have been...

The analyses below compare the career histories and personal characteristics of the executives in the top ranks of the world's largest and most stable business operations, the Fortune 100, between 1980 and 2001. To our knowledge, there have been no prior studies of contemporary changes in the...

This study is an attempt to evaluate the effects of product and labour market regulations on industry productivity through their various impacts on changes in production prices and wages. In a first stage, the estimation of a regression equation on an industry*country panel, with controls for...

In an 80-country panel since the 1960s, the convergence rate for per capita GDP is around 1.7% per year. This "beta convergence" is conditional on an array of explanatory variables that hold constant countries' long-run characteristics. The introduction of country fixed effects generates a much...

This paper introduces a model of endogenous growth through basic and applied research. Basic research differs from applied research in the nature and the magnitude of the generated spillovers. We propose a novel way of empirically identifying these spillovers and embed them in a general...

Our study aims at assessing the actual importance of the two main channels usually contemplated in the literature through which upstream sector anticompetitive regulations may impact productivity growth: business investments in R&D and in ICT. We thus estimate what are the specific impacts of...

Productivity improvements within establishments (e.g., factories, mines, or retail stores) are an important source of aggregate productivity growth. Past research has documented that learning by doing-productivity improvements that occur in concert with production increases-is one source of such...

This paper examines how international flows of technological knowledge affect economic performance across industries and firms in different countries. Motivated by the large share of the world's technology investments made by firms that are active across borders, we focus on international trade...
