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 TFP differences across firms and countries. This review paper discusses what has...

A long-standing question in social science is to what extent differences in management cause differences in firm performance. To investigate this we ran a management field experiment on large Indian textile firms. We provided free consulting on modern management practices to a randomly chosen...

Are poor management practices holding back middle-income countries? The authors look at evidence for private firms and public organisations in India - in manufacturing, retail, healthcare and education.

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...

Without the 'spillover effects' of open content production, the growth in Wikipedia editing activity between 2002 and 2010 would have been halved. That is the central finding of research by Aleksi Aaltonen and Stephan Seiler, which analyses editing data by Wikipedia users to show how content...

Using detailed edit-level data over eight years across a large number of articles on Wikipedia, we find evidence for a positive spillover effect in editing activity. Cumulative past contributions, embodied by the current article length, lead to significantly more editing activity, while...

John Van Reenen sketches the evolution of CEP research on the drivers of productivity growth - and its impact on policies to foster competition.

Economists have long puzzled over the astounding differences in productivity between firms and countries. For example, looking at disaggregated data on U.S. manufacturing industries, Syverson (2004a) found that plants at the 90th percentile produced four times as much as the plant in the 10th...

We use an innovative survey tool to collect management practice data from over 4,000 medium sized manufacturing firms across Asia, Europe and the US. These measures of managerial practice are strongly associated with firm-level performance (e.g. productivity, profitability and stock market...

A classic question in industrial organization is whether competition raises productivity and if so, through what mechanism? I discuss recent empirical evidence from both large-scale databases and specific industries which suggests that tougher competition does indeed raise productivity and one...
