  The Impact of CEOs in the Public Sector: Evidence from the English NHS
  Katharina Janke, Carol Propper and Raffaella Sadun
  We investigate whether top managers affect the performance of large public sector organizations. As our case study we examine CEOs of English public hospitals, which are large, complex organizations with multi-million turnover. We study the impact of individual CEOs on a wide set of measures of hospital performance, intermediate operational outcomes and inputs. We adopt two econometric approaches: a parametric approach that exploits the movement of CEOs across different hospitals and a non-parametric difference-in-difference matching estimator. Overall, we find little evidence that individual CEOs have an impact on a large set of measures of hospital performance. This result is not due to the allocation of good performers to poorly performing hospitals.

The Strategy unit studies firms as competitors in an economic landscape. Key issues include: the development and effectiveness of firm strategy at both a business and corporate level; the analysis of the competitive environment; and the sustainability of strategy over time.

Our research, course development, and teaching draws on multiple disciplines, including economics, sociology, and political science, and focuses on both domestic and global competition. The objective of the work is to generate findings and develop concepts that will help managers improve their strategic decisions while advancing the state of knowledge in the academic study of strategy and related disciplines.

The Impact of CEOs in the Public Sector: Evidence from the English NHS

re Raffaella Sadun

To what extent do CEOs impact their organizations? This study finds little consistent evidence of any CEO effect on the large set of production metrics examined in hospitals averaging 4,500 employees

This study provides the first quasi-experimental estimate of the long-run elasticity (responsiveness) of residential electricity demand, and finds that it is about double the short-run elasticity. Ou

Transaction Costs and the Duration of Contracts

re Alexander J. MacKay

When buyers transact with sellers, they select not only whom to transact with but also for how long. This paper develops a model of optimal contract duration arising from underlying supply costs and
