Changes in Persistence of Performance Over Time

One of the central puzzles of strategy is the persistence of performance. We revisit a research tradition that lays out trends in persistence of performance, to create shared facts for strategy scholars to explain. We extend the time series from prior studies and apply recent methods for measuring performance persistence. We show that persistence of performance is not stable. Notably, our measure shows a decrease in persistence from the beginning of the sample to roughly 2000, followed by a marked increase thereafter. Our evidence suggests that the post-2000 increase in persistence is at least partly attributable to increases in industry concentration associated with the greater importance of software across industries in the late 1990s

The Contingent Effect of Management Practices

This paper investigates how the success of a management practice depends on the nature of the long-term relationship between the firm and its employees. A large US transportation company is in the process of fitting its trucks with an electronic on-board recorder (EOBR), which provide drivers with information on their driving performance. In this setting, a natural question is whether the optimal managerial practice consists of: (1) Letting each driver know his or her individual performance only; or (2) Also providing drivers with information about their ranking with respect to other drivers. The company is also in the first phase of a multi-year initiative to remake its internal operations. This first phase corresponds to an overhaul of the relational contract with its employees, focusing exclusively on changing values toward a greater emphasis on teamwork and empowerment. The main result of our randomized experiment is that (2) leads to better performance than (1) in a particular site if and only if the site has not yet received the values intervention, and worse performance if it has. The result is consistent with the presence of a conflict between competition-based managerial practices and a cooperation-based relational contract. More broadly, it highlights the role of intangible relational factors in determining the optimal set of managerial practices

Corporate Purpose and Financial Performance

We construct a measure of corporate purpose within a sample of US companies based on approximately 500,000 survey responses of worker perceptions about their employers. We find that this measure of purpose is not related to financial performance. However, high purpose firms come in two forms: firms that are characterized by high camaraderie between workers and firms that are characterized by high clarity from management. We document that firms exhibiting both high purpose and clarity have systematically higher future accounting and stock market performance, even after controlling for current performance, and that this relation is driven by the perceptions of middle management and professional staff rather than senior executives, hourly or commissioned workers. Taken together, these results suggest that firms with employees that maintain strong beliefs in the meaning of their work experience better performance
