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

by Katharina Janke, Carol Propper, and 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 in the English National Health Service. This result stands in stark contrast with earlier findings of a CEO effect in the private sector and smaller public sector organizations.

Come Together: Firm Boundaries and Delegation

by Laura Alfaro, Nick Bloom, Paola Conconi, Harald Fadinger, Patrick Legros, Andrew F. Newman, Raffaella Sadun, and John Van Reenen

The study develops a simple model and provides new data to examine the relationship between vertical integration and delegation of decision-making, two critical aspects of a firm organizational design that are typically studied in isolation. The results show that delegation and vertical integration are positively correlated.

Turbulence, Firm Decentralization and Growth in Bad Times

by Philippe Aghion, Nicholas Bloom, Brian Lucking, Raffaella Sadun, and John Van Reenen

What makes some firms more resilient than others to large negative macro shocks? This paper finds that the internal organization of firms—specifically, the extent to which decision-making is decentralized from headquarters to plant managers—is an important mediating factor through which macroeconomic shocks affect firm performance and, ultimately, growth.

CEO Behavior and Firm Performance

by Oriana Bandiera, Stephen Hansen, Andrea Pratt, and Raffaella Sadun

This paper combines a new survey methodology with a machine learning algorithm to measure the behavior of CEOs in large samples. Results show that larger and more complex firms require CEOs with a more coordinative—and less micromanaging—behavior. Inefficiencies in the way CEOs match with firms have important consequences for firm productivity.

Management as a Technology?

by Nicholas Bloom, Raffaella Sadun, and John Van Reenen

Economists, business people and many policymakers have long believed that management practices are an important element in productivity. This study provides firm-level measures of management in an internationally comparable way, drawing on original data on over 11,000 firms across 34 countries. Differences in management practices account for about 30 percent of cross-country productivity differences.

Does Management Matter in Schools?

by Nicholas Bloom, Renata Lemos, Raffaella Sadun & John Van Reenen

There are major disparities in the quality of education within and across countries. School managerial practices may be one important reason for such differences, but research in this area has traditionally been held back by a lack of robust and comparable instruments to systematically measure management practices. In this paper the authors develop a novel and internationally comparable index of management quality for schools, and apply this methodology to measure management practices across 1,800 private and public schools across eight developed and developing economies. Three key findings emerged. First, the adoption of basic managerial practices varies significantly across and within countries. The United Kingdom, Sweden, Canada and the US obtain the highest average scores, followed by Germany, Italy and Brazil, while India has the lowest scores. Second, higher management scores are positively correlated with better pupil outcomes. Third, they show that that—similar to the private sector—different types of school governance are associated with systematically different levels of management adoption. Key concepts include: Management practices vary significantly across and within countries and are strongly linked to pupil outcomes. Among autonomous government schools, two key features account for a large fraction of the superior management performance of such schools: 1) having strong accountability of principals to an external governing body and 2) exercising strong leadership through a coherent long-term strategy for the school. Improving management could raise school standards and could give broad support for the fostering of greater autonomy of government schools. Autonomy by itself is unlikely to deliver better results. However, finding ways to improve governance and motivate principals could make sure that decentralized power leads to better standards. Closed for comment; 0 Comment(s) posted.

Family CEOs Spend Less Time at Work

by Carmen Nobel

CEOs who are related to the owners of family-owned firms work significantly fewer hours than nonfamily CEOs, according to a new study by Raffaella Sadun and colleagues. This is in light of the fact that longer working hours are associated with higher productivity, growth, and profitability. Closed for comment; 16 Comment(s) posted.

Managing the Family Firm: Evidence from CEOs at Work

by Oriana Bandiera, Andrea Prat & Raffaella Sadun

According to prior research, firm performance is weaker among companies with CEOs who have a family connection to the firm owners compared with nonfamily CEOs, that is professionals. Given the ubiquity of family firms and the implications for aggregate income and growth, what explains this variation? This paper provides evidence on the causes, features, and correlates of CEO attention allocation by looking at a simple yet critical difference between family and professional CEOs: the time they spend working for their firms. The Indian manufacturing sector makes an excellent case study because family ownership is widespread and the productivity dispersion across firms is substantial. Examining the time allocation of 356 CEOs of listed firms in this sector, the authors make several findings. First, there is substantial variation in the number of hours CEOs devote to work activities. Longer working hours are associated with higher firm productivity, growth, profitability, and CEO pay. Second, family CEOs record 8 percent fewer working hours relative to professional CEOs. The difference in hours worked is more pronounced in low-competition environments and does not seem to be explained by measurement error. Third, estimates with respect to the cost of effort, due to weather shocks and popular sport events, suggest that family CEOs place a higher relative weight on leisure, which could be due to either a wealth effect or job security. Overall, the evidence highlights the importance of how corporate leaders allocate their managerial attention. Key concepts include: Family CEOs work 8 percent fewer hours that nonfamily CEOs (i.e., professionals). The difference in hours worked translates in a 5.8 percent productivity gap between family and professional CEOs. Family CEOs are more responsive to events that increase the cost of providing effort, such as monsoon rains and cricket matches. Behavioral differences may help account for the performance differential between family and nonfamily firms. Closed for comment; 0 Comment(s) posted.

Measuring the Efficacy of the World’s Managers

The Organization of Firms Across Countries

by Nicholas Bloom, Rafaella Sadun & John Van Reenen

Economists have been paying increasing attention to the role that culture plays in a firm's overall performance. This paper focuses on how trust—a key cultural factor—affects firms' decision-making process, size, and productivity. Research was conducted by Nicholas Bloom of Stanford University, Rafaella Sadun of the Harvard Business School, and John Van Reenen of the London School of Economics. Key concepts include: If a firm is headquartered in a country where trust is prevalent (such as Sweden), it is much more likely to decentralize its decision making than if it is headquartered in a country in which trust is rarer (such as India). In short, higher trust leads to more decentralization. Trust also enables a firm to hire a large number of plant managers, because the CEO will feel comfortable delegating decisions to their direct reports without spending too much time on supervision. Thus, higher trust increases firm size. Higher trust increases the marginal value of information technology's effect on productivity. Closed for comment; 0 Comment(s) posted.
