Inter‐temporal economies of scope,organizational modularity,and the dynamics of diversification

The question of whether corporations add value beyond that created by individual businesses has engendered much debate in recent years. Some of this debate has focused on the pros and cons of related vs. unrelated diversification. A standard explanation of the benefits of related diversification has to do with the ability to obtain intra‐temporal economies of scope from contemporaneous sharing of resources by related businesses within the firm. In contrast, this paper deals with inter‐temporal economies of scope that firms achieve by redeploying resources and capabilities between related businesses over time, as firms exit some markets while entering others. The transfer of resources due to market exit distinguishes our treatment of inter‐temporal economies of scope from standard intra‐temporal economies of scope. In addition, these inter‐temporal economies can benefit from a decentralized and modular organizational structure. This ability to obtain inter‐temporal economies of scope via organizational modularity and recombination suggests that corporations do not necessarily need a high degree of coordination between business units in order to benefit from a strategy of related diversification.

A Conversation with Katherine K. Wallman

Katherine Wallman has had a highly distinguished career in federal statistics and has been serving as the Chief Statistician in the USA for the last 22 years. She was also the President of the American Statistical Association (ASA) in 1992. This interview starts with Wallman's early career and introduction to the field of statistics and goes on to describe her fascinating journey and many accomplishments. The interview was conducted on 19 November 2014. The author thanks Mary Ann Kasper, CNSTAT staff, for transcribing.     

Overtime pay regulation and weekly hours of work in Canada

The idea that overtime pay regulation can be used to create employment continues to receive attention in a variety of countries. Standard hours, beyond which a statutory overtime premium must be paid, varies across Canadian provinces, as do coverage rules. Exploiting this variation produces a smaller estimated response of weekly hours to standard hours than previous researchers have found in other countries. Combined with evidence of substantially more moonlighting and higher wages in jurisdictions with lower standard hours, these results support a somewhat pessimistic view of the idea that reducing standard hours can be used promote work-sharing in Canada.     

A MATHEMATICAL MODEL OF THE ADAPTIVE BEHAVIOUR OF ORGANIZATIONS

The recent work on organizational configuration and quantum structural change by Miller and Friesen (1984), and on the population ecology of organizations by Hannan and Freeman (1978, 1983) suggests some integral relationships between eiivironments, structure and optimal adaptive strategies. These appear to warrant a more systematic and formal analysis. Towards that end a mathematical model is developed to show the way organizations adapt t o changing environments. Using a Markovian representation, three types of environments are examined t o test the implications that the model has for adopting strategies of generalism vs. specialism, concerted ‘quantum’ 71,s. piecemeal change, and batching changes together vs. changing gradually and promptly.     

The Ranchers' Choice Cooperative: What Happened?

This case considers a "new generation" value-added cooperative in southern Colorado that marketed kosher and natural beef and lamb products until a fire in the processing plant halted operations. The case profiles the history and strategy of the Ranchers' Choice Cooperative and illustrates the challenges of transforming a good idea into a profitable one.     

Innovation in conservative and entrepreneurial firms: Two models of strategic momentum

Two very different models of product innovation are postulated and tested. The conservative model assumes that innovation is performed reluctantly, mainly in response to serious challenges. It therefore predicts that innovation will correlate positively with environmental, information processing, structural and decision making variables that represent, or help to recognize and cope with these challenges. In contrast, the entrepreneurial model supposes that innovation is always aggressively pursued and will be very high unless decision makers are warned to slow down. Thus negative correlations are predicted between innovation and the variables that can provide such warning. Correlational and curvilinear regression analyses revealed that each model was supported by conservative and entrepreneurial sub-samples, respectively, in a diverse sample of 52 Canadian firms.     

How do school ‘report cards’ affect school choice decisions?

Abstract. We estimate the effect of information about school achievement that is disseminated to the public through websites and school ‘report cards’ on school choice decisions. We find that students are more likely to leave their school when public information reveals poor school‐level performance. Some parents’ school choice decisions respond to information soon after it becomes available. Others, including non‐English‐speaking parents, alter their school choice decisions only in response to information that has been disseminated widely and discussed in the media. Parents in low‐income neighbourhoods are most likely to alter their school choice decisions in response to new information. JEL classification: I21, D83     

CEO duality,succession, capabilities and agency theory: commentary and research agenda

We offer a new explanation for the relationship between CEO duality and firm performance that accounts for managerial capabilities and succession planning. Our reinterpretation of findings by Worrell, Nemec and Davidson (1997) is consistent with the new explanation. We also make suggestions for future research. © 1998 John Wiley & Sons, Ltd.
