On the necessary and sufficient conditions for Nash implementation

The purpose of this paper is to provide a constructive way of checking whether or not a social choice correspondence can be implemented in Nash equilibria. The results apply when there are two or more players. The usefulness of this constructive approach is illustrated for the case of single-peaked preferences over , a two-person public good economy with monotonic preferences, and a two-person exchange economy with monotonic preferences.I am grateful to Rajeev Bhattacharya, William Thomson, Takehiko Yamato, and an anonymous referee, for helpful comments.

Supply Chain Knowledge and Performance: A Meta‐Analysis

Many firms make significant investments into developing and managing knowledge within their supply chains. Such investments are often prudent because studies indicate that supply chain knowledge (SCK) has a positive influence on performance. Key questions still surround the SCK–performance relationship, however. First, what is the overall relationship between SCK and performance? Second, under what conditions is the relationship stronger or weaker? To address these questions, we applied meta‐analysis to 35 studies of the SCK–performance relationship that collectively include more than 8,400 firms. Our conservative estimate is that the effect size of the overall relationship is  = .39. We also find that the SCK–performance relationship is stronger when (i) examining operational performance, (ii) gathering data from more than one supply chain node, (iii) gathering data from multiple countries, (iv) examining service industries, and (v) among more recently published studies. We also found that studies that embraced a single theory base (as opposed to using multiple ones) had a stronger SCK–performance relationship. Looking to the future, our meta‐analysis highlights the need for studies to (i) include lags between the measurement of SCK and performance, (ii) gather upstream data when examining innovation, (iii) examine SCK within emerging countries, and (iv) provide much more information relative to the nuances of the SCK examined.     

Knowledge Management and Balanced Scorecard Outcomes: Exploring the Importance of Interpretation,Learning and Internationality

The topics of shared interpretation, organizational learning and firm internationalization have been studied extensively. Though considered important factors that shape the international competitive landscape, research synthesizing these interrelated areas has been limited to date. We use the balanced scorecard as a framework for assessing how organizational learning and sensemaking influence actions relating to a global marketing strategy and subsequent financial performance. Using data from 169 multinational corporations, findings indicate that a specific set of knowledge activities is related to balanced scorecard outcomes (e.g. customer performance, innovation and learning performance, and internal process performance). The hypothesized importance of customer performance is confirmed as the only balanced scorecard outcome significantly related to financial performance. A post hoc analysis revealed further insights for future research opportunities. Overall, these results suggest that firms can improve their competitive position by emphasizing shared interpretation within the organization and including balanced scorecard elements when assessing performance.     

Does managers' motivation matter? Exploring the associations between motivation,transformational leadership,and innovation in a religious organization

Religious organizations are social systems operating in a complex and changing environment. By looking to an authority beyond themselves, religious organizations have comparatively little control over defining their own goals. In this juggling between sticking to the ultimate goal of an organization and adapting to complex changing environments, that is, in the juggling between tradition and renewal, transformational leadership seems to play an important role in religious organizations. The extensive body of literature on transformational leadership has focused more on the outcomes of transformational leadership than on its antecedents. We extend the existing literature by linking managers' motivation to their transformational leadership behaviors in a religious organization. More specifically, we examined the associations of intrinsic and prosocial motivation with transformational leadership, and we investigated the relationship between transformational leadership and innovation among 252 managers in the largest nonprofit organization in Norway, the Church of Norway. Analyses in structural equation modeling revealed a positive relationship between intrinsic motivation and transformational leadership, whereas the relationship between prosocial motivation and transformational leadership was not significant. Transformational leadership was positively associated with innovation. Based on the results of the study, we discuss practical implications regarding how to support intrinsic motivation, transformational leadership, and innovation in religious organizations.     

Fertility and women's employment reconsidered: A macro-level time-series analysis for developed countries, 1960–2000

This paper examines causality and parameter instability in the long-run relationship between fertility and women's employment. This is done by a cross-national comparison of macro-level time-series data from 1960 to 2000 for France, West Germany, Italy, Sweden, the UK, and the USA. By applying vector error correction models (a combination of Granger-causality tests with recent econometric time-series techniques) we find causality in both directions. This finding is consistent with simultaneous movements of both variables brought about by common exogenous factors such as social norms, social institutions, financial incentives, and the availability and acceptability of contraception. We find a negative and significant correlation until about the mid-1970s and an insignificant or weaker negative correlation afterwards. This result is consistent with a recent hypothesis in the demographic literature according to which changes in the institutional context, such as changes in childcare availability and attitudes towards working mothers, might have reduced the incompatibility between child-rearing and the employment of women.     

Risk Uncertainty and Supply Chain Decisions: A Real Options Perspective

Supply chain risk uncertainty can create severe repercussions, thus it is not surprising that research interest in supply chain risk has been growing. While extant inquiry is informative, there is a lack of investigations that center on supply chain investment decisions when facing high levels of risk uncertainty. Given the potential dollar value involved in these decisions, an understanding of how these supply chain decisions are made is of significant theoretical and practical importance. Real options theory, with its focus on decision making under conditions of uncertainty, is an appealing theoretical lens for this endeavor. In essence, real options theory asserts that managerial decisions center on creating and then exercising or not exercising certain opportunities. To date, theorizing about and investigations of real options have used firms as their focus. Not yet examined are real options within supply chains that cross firm boundaries and drive much of the competitive activity in the modern economy. Accordingly, we extend real options theory to the supply chain context by examining how different types of options are approached relative to supply chain project investments. Specifically, we theorize how the options will be related to perceived value under conditions of high supply chain risk uncertainty. Overall, our investigation builds knowledge by extending real options theory to the supply chain context and by providing evidence suggesting some options operate differently in supply chains than they do in firms.     

Understanding Drivers of Risk‐Adjusted Performance for Service Firms with International Operations*

This article investigates whether international operations of service firms increase performance while reducing risk. The article draws on a longitudinal dataset of 584 internationally operating service firms from the United States. Analysis indicates that international diversification is negatively related to risk‐adjusted performance. However, it is established that international diversification interacts with internationalization and positively influences risk‐adjusted performance. This finding offers significant promise for firms, as it indicates that international operations (if managed well), through exposure to varied foreign markets coupled with adequate global scope, can lead to firms’ increased risk‐adjusted performance. The results provide a mechanism for decision‐makers to better understand international operations of service firms and present a strategy for achieving success in international markets by effectively managing two important levers: internationalization and international market diversification.
