|February 2012||Management Practices Across Firms and Countries|
with Nicholas Bloom, Raffaella Sadun, John Van Reenen: w17850
For the last decade we have been using double-blind survey techniques and randomized sampling to construct management data on over 10,000 organizations across twenty countries. On average, we find that in manufacturing American, Japanese, and German firms are the best managed. Firms in developing countries, such as Brazil, China and India tend to be poorly managed. American retail firms and hospitals are also well managed by international standards, although American schools are worse managed than those in several other developed countries. We also find substantial variation in management practices across organizations in every country and every sector, mirroring the heterogeneity in the spread of performance in these sectors. One factor linked to this variation is ownership. Government, f...

|June 2011||Leveraging Monopoly Power by Degrading Interoperability: Theory and Evidence from Computer Markets|
with Kai-Uwe Kühn, John Van Reenen: w17172
When will a monopolist have incentives to foreclose a complementary market by degrading compatibility/interoperability of his products with those of rivals? We develop a framework where leveraging extracts more rents from the monopoly market by "restoring" second degree price discrimination. In a random coefficient model with complements we derive a policy test for when incentives to reduce rival quality will hold. Our application is to Microsoft's strategic incentives to leverage market power from personal computer to server operating systems. We estimate a structural random coefficients demand system which allows for complements (PCs and servers). Our estimates suggest that there were incentives to reduce interoperability which were particularly strong at the turn of the 21st Century.

|October 2008||Modern Management: Good for the Environment or just Hot Air?|
with Nicholas Bloom, Ralf Martin, Raffaella Sadun: w14394
We use an innovative methodology to measure management practices in over 300 manufacturing firms in the UK. We then match this management data to production and energy usage information for establishments owned by these firms. We find that establishments in better managed firms are significantly less energy intensive. They use less energy per unit of output, and also in relation to other factor inputs. This is quantitatively substantial: going from the 25th to the 75th percentile of management practices is associated with a 17.4% reduction in energy intensity. This negative relationship is robust to a variety of controls for industry, location, technology and other factor inputs. Better managed firms are also significantly more productive. One interpretation of these results is that well m...
