The Distinct Effects of Information Technology and Communication Technology on Firm Organization

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 of control. Consistently with the theory we find that better information technologies (Enterprise Resource Planning for plant managers and CAD/CAM for production workers) are associated with more autonomy and a wider span of control. By contrast, communication technologies (like data networks) decrease autonomy for both workers and plant managers. Our findings are robust to using exogenous variation in cross-country telecommunication costs arising from differential regulatory regimes.

MODERN MANAGEMENT: GOOD FOR THE ENVIRONMENT OR JUST HOT AIR?*

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 managed firms are adopting modern lean manufacturing practices, which allows them to increase productivity by using energy more efficiently. This suggests that improving the management practices of manufacturing firms may help to reduce greenhouse gas emissions.

Regulation and UK Retailing Productivity: Evidence from Microdata

We use UK micro data to explore whether planning regulation reduced UK retailing productivity growth between 1997 and 2003. We document a shift to smaller shops, particularly within supermarket chains, following a regulatory change in 1996 which increased the costs of opening large stores. This might have caused a slowdown in productivity growth if firms (a) lose scale advantages, by moving to smaller stores and (b) lose scope advantages if existing organisational knowledge appropriate to larger stores is not perfectly substitutable with the organisational capital required to run smaller stores. Our micro data shows a relation, controlling for fixed effects, between chain-level TFP for multi-store chains and various measures of the size of the stores within the chain. Our results suggest the fall in within-chain shop sizes was associated with a lowering of chain TFP by about 0.4% pa, about 40% of the post-1995 slowdown in UK retail TFP growth. The foregone productivity works out at about £80,000 per small chain supermarket store.

Does Management Matter in Schools

We collect data on operations, targets and human resources management practices in over 1,800 schools educating 15-year-olds in eight countries. Overall, we show that higher management quality is strongly associated with better educational outcomes. The UK, Sweden, Canada and the US obtain the highest management scores closely followed by Germany, with a gap to Italy, Brazil and then finally India. We also show that autonomous government schools (i.e. government funded but with substantial independence like UK academies and US charters) have significantly higher management scores than regular government schools and private schools. Almost half of the difference between the management scores of autonomous government schools and regular government schools is accounted for by differences in leadership of the principal and better governance.

Hospital Board And Management Practices Are Strongly Related To Hospital Performance On Clinical Quality Metrics

National policies to improve health care quality have largely focused on clinical provider outcomes and, more recently, payment reform. Yet the association between hospital leadership and quality, although crucial to driving quality improvement, has not been explored in depth. We collected data from surveys of nationally representative groups of hospitals in the United States and England to examine the relationships among hospital boards, management practices of front-line managers, and the quality of care delivered. First, we found that hospitals with more effective management practices provided higher-quality care. Second, higher-rated hospital boards had superior performance by hospital management staff. Finally, we identified two signatures of high-performing hospital boards and management practice. Hospitals with boards that paid greater attention to clinical quality had management that better monitored quality performance. Similarly, we found that hospitals with boards that used clinical quality metrics more effectively had higher performance by hospital management staff on target setting and operations. These findings help increase understanding of the dynamics among boards, front-line management, and quality of care and could provide new targets for improving care delivery.

Matching Firms, Managers, and Incentives

We combine unique administrative and survey data to study the match between firms and managers. The data include manager characteristics, firm characteristics, detailed measures of managerial practices, and outcomes for the firm and the manager. A parsimonious model of matching and incentives generates implications that we test with our data. We use the model to illustrate how risk aversion and talent determine how firms select and motivate managers. We show that empirical links between firm governance, incentives, and performance, which have so far been studied in isolation, can instead all be interpreted within our simple unified matching framework.

Managing the Family Firm: Evidence from CEOs at Work

We develop a new survey instrument to codify CEOs’ diaries in large samples and use it to measure the labor supply of 1,114 family and professional CEOs of manufacturing firms across six countries (Brazil, France, Germany, India, the United Kingdom and the United States). By this measure, family CEOs work 9% fewer hours relative to professional CEOs, even when we control for a wide range of CEO, firm and industry characteristics. The differences in hours worked between family and professional CEOs are larger when the opportunity cost of leisure is lower. We interpret these results as evidence of differences in preferences for leisure across CEOs rather than optimal responses to organizational differences correlated with ownership. Differences in labor supply are larger in countries where inheritance laws favor wealth concentration and are correlated with differences in firm performance.

Span of Control and Span of Attention

Using novel data on CEO time use, we document the relationship between the size and composition of the executive team and the attention of the CEO. We combine information about CEO span of control for a sample of 65 companies with detailed data on how CEOs allocate their time, which we define as their span of attention. CEOs with larger executive teams do not save time for personal use, or to cultivate external constituencies. Instead, CEOs with broader spans of control invest more in a “team” model of interaction. They spend more time internally, specifically in pre-planned meetings that have more participants from different functions. The complementarity between span of control and the team model of interaction is more prevalent in larger firms.

Come Together: Firm Boundaries and Delegation

Little is known theoretically, and even less empirically, about the relationship between firm boundaries and the allocation of decision rights within firms. We develop a model in which firms choose which suppliers to integrate and whether to delegate decisions to integrated suppliers. We test the predictions of the model using a novel dataset that combines measures of vertical integration and delegation for a large set of firms from many countries and industries. In line with the model’s predictions, we obtain three main results: (i) integration and delegation co-vary positively; (ii) producers are more likely to integrate suppliers in input sectors with greater productivity variation (as the option value of integration is greater); and (iii) producers are more likely to integrate suppliers of more important inputs and to delegate decisions to them.
