International Data on Measuring Management Practices, 2016. (with N Bloom, R Lemos, R Sadun and J Van Reenen)

Rapid advances in computer power and increased openness of national statistical agencies have led to unprecedented availability of large datasets. Consider three types of firm datasets. First, governments collect administrative data on firms: information on jobs, investment and output has long been collected to calculate national, industrial and regional statistics. Second, there has been an explosion of Big Data – various forms of data typically created for business purposes. Products like ORBIS contain over 50 million firms from almost every country in the world and can be used to address many questions. Another example is Compustat, which contains extensive data for about 6,000 listed US firms but excludes the other 99% of private firms. We focus on a third type of international firm data, which is collected from surveys. In an age of rich administrative and Big Data why bother with such surveys?

The New Empirical Economics of Management, 2014. (with N Bloom, R Lemos, R Sadun and J Van Reenen)
Journal of the European Economic Association, 12(4)

Over the last decade the World Management Survey (WMS) has collected firm-level management practices data across multiple sectors and countries. We developed the survey to try to explain the large and persistent total factor productivity (TFP) differences across firms and countries. This review paper discusses what has been learned empirically and theoretically from the WMS and other recent work on management practices. Our preliminary results suggest that about a quarter of cross-country and within-country TFP gaps can be accounted for by management practices. Management seems to matter both qualitatively and quantitatively for performance at the level of the firm and the nation. Competition, governance, human capital, and informational frictions help account for the variation in management. We make some suggestions for both policy and future research.
