| July 2009 | The organization of firms across countries
with Nicholas Bloom, John Van Reenen: w15129
We argue that social capital as proxied by regional trust and the Rule of Law can improve aggregate productivity through facilitating greater firm decentralization. We collect original data on the decentralization of investment, hiring, production and sales decisions from Corporate Head Quarters to local plant managers in almost 4,000 firms in the US, Europe and Asia. We find Anglo-Saxon and Northern European firms are much more decentralized than those from Southern Europe and Asia. Trust and the Rule of Law appear to facilitate delegation by improving co-operation, even when we examine "bilateral trust" between the country of origin and location for affiliates of multinational firms. We show that areas with higher trust and stronger rule of law specialize in industries that rely on decen... |
| May 2009 | The distinct effects of Information Technology and Communication Technology on firm organization
with Nicholas Bloom, Luis Garicano, John Van Reenen: w14975
Empirical studies on information communication technologies (ICT) typically aggregate the "information" and "communication" components together. We show theoretically and empirically that these have very different effects on the empowerment of employees, and by extension on wage inequality. If managerial hierarchies are devices to acquire and transmit knowledge and information, technologies that reduce information costs enable agents to acquire more knowledge and 'empower' lower level agents. Conversely, technologies reducing communication costs substitute agent's knowledge for directions from their managers, and lead to centralization. Using an original dataset of firms in the US and seven European countries we study the impact of ICT on worker autonomy, plant manager autonomy and spans o... |
| October 2008 | Modern Management: Good for the Environment or just Hot Air?
with Nicholas Bloom, Christos Genakos, Ralf Martin: 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... |
| May 2007 | Americans Do I.T. Better: US Multinationals and the Productivity Miracle
with Nicholas Bloom, John Van Reenen: w13085
The US has experienced a sustained increase in productivity growth since the mid-1990s, particularly in sectors that intensively use information technologies (IT). This has not occurred in Europe. If the US "productivity miracle" is due to a natural advantage of being located in the US then we would not expect to see any evidence of it for US establishments located abroad. This paper shows in fact that US multinationals operating in the UK do have higher productivity than non-US multinationals in the UK, and this is primarily due to the higher productivity of their IT. Furthermore, establishments that are taken over by US multinationals increase the productivity of their IT, whereas observationally identical establishments taken over by non-US multinationals do not. One explanation for the... |
