This paper investigates the presence of global style factors in global equity investment. To this end, we apply Bayesian variable selection methods from the statistics literature to give guidance in the decision to include/omit factors in a global (linear factor) stock return model. Once we have accounted for country and sector, it is possible to see which style or styles best explains current asset returns. This study does not find compelling evidence for global styles as useful explanatory factors in a fixed parameter regression model, once country and sector have been accounted for.  相似文献

This paper makes a positive contribution to Cowling and Sugden’s recent work on the theory of the firm. We focus on their novel definition of the firm as a ‘means of coordinating production from one centre of strategic decision‐making’. We extend this definition to account for the fact that strategic decision‐makers engaged in the coordination of production operate under conditions of ‘fundamental uncertainty’. The significance of such an extension is that it avoids many of the problems associated with Cowling and Sugden’s framework while reinforcing their main conclusions and providing a technical definition of the concept of strategy.  相似文献

From the beginning, the same or similar opportunities and concerns have arisen at each step in International Leadership Association (ILA)–sponsored conversations and actions related to guidelines, standards, and accreditation of leadership education programs in higher education. Opportunities include increased legitimacy, program development, and more robust responses to external accreditation requirements. Concerns include dampening autonomy and creativity, skepticism that such a diverse field could be evaluated by a common program review model, increased bureaucratization, and, with regard to external review, ethical concerns. Because these conversations and actions have occurred over the past 8 years and have culminated most recently with preliminary recommendations of the ILA's Task Force on Formalized Program Review, we can learn from the history of the debates around these issues and the solutions that were derived to address them. The most salient of these solutions is found in the logic of the process order of Guiding Questions: Guidelines for Leadership Education Programs. The first step in Guiding Questions is for program faculty to produce a written conceptual framework that is grounded not only in theory but also in the context of the institution, college, and department. This should preserve local autonomy and creativity. Further, emphasis for evaluation purposes on program content, teaching and learning methods, and assessment and outcomes measures that are coherent and consistent with these locally derived conceptual frameworks should allow broad application across the diversity of the field. Local control should also minimize bureaucratization and help mitigate ethical concerns. The trend is toward increasing support for formalized program review. Concerns as well as opportunities remain. However, others, including external accrediting organizations and institutional effectiveness offices, should not be determining the terms of our legitimacy and accountability. We must do that for ourselves. Building on what we have learned over the past 8 years shows the way forward.  相似文献

Market power in the input purchase is becoming increasingly common because of growing consolidation and mergers and also due to multinational firms establishing a stronghold in buying inputs in the developing countries. In this study, we formulate a general equilibrium model consisting of a competitive sector and an oligopsony sector which exercises market power over inputs. Our results indicate that if the oligopsony sector incurs a higher marginal factor cost for the intensive factor, basic results of the standard two-sector model continue to hold. But if the marginal factor cost is higher for the non-intensive factor, then factor intensities in the physical and value sense differ and traditional trade propositions such as the Stolper–Samuelson theorem do not hold.  相似文献

Research on family-friendly practices has concentrated on the predictors of their use, particularly from the perspective of either institutional theory or the high involvement or commitment management vogue. This paper first shows how such perspectives can be used to generate hypotheses about the link between family-friendly management and organizational performance. Second, the paper reports research designed to test these, using data from a national representative sample of workplaces across the British economy, the Workplace Employment Relations Survey of 2004 (WERS2004). The results support the high commitment thesis that family-friendly management will strengthen the relationship between commitment and key economic outcomes, as the relationships between workforce commitment and productivity or quality are stronger in organizations when friendly management is high, which is consistent with social exchange theory. Family-friendly management is not, however, related to the human resource outcomes of labour turnover and absenteeism. Nor does the study find support for the argument that its use in conjunction with high involvement management enhances the performance effects of both. Equally, there is no support for the hypothesis from the institutional thesis that family-friendly management has positive effects on the legitimacy of the organization.  相似文献

Unit root tests, seeking mean or trend reversion, are frequently applied to panel data. We show that more powerful variants of commonly applied tests are readily available. Moreover, power gains persist when the modifications are applied to bootstrap procedures that may be employed when cross‐correlation of a rather general sort among individual panel members is suspected.

Municipal aggregation and retail competition in the Ohio energy sector   总被引:1,自引:0,他引:1  
Ohio allows communities to vote to aggregate the loads of individual consumers (unless they opt out) in order to seek a competitive energy supplier. Over 200 communities have voted to do this for electricity. By 2004 residential switching reached 69% in Cleveland territory (95% from municipal aggregation) but by 2006 had fallen to 8%. Savings are now small, but customer acquisition costs are low and the cost to consumers is negligible. Aggregation and retail competition have been thwarted by Rate Stabilization Plans holding incumbent utility prices below cost since 2006. In the Ohio gas sector, rate regulation has not discouraged aggregation and competition, but market prices falling below municipally negotiated rates can be politically embarrassing. Municipal aggregation thus works when conditions allow it, and enhances competition. How it would fare against individual choice in a market conducive to retail competition remains an open question.   相似文献

We investigate the welfare effects of inflation in economies with search frictions and menu costs. We first analyze an economy where there is no transaction demand for money balances: Money is a mere unit of account. We determine a condition under which strictly positive inflation is desirable. We relate this condition to a standard efficiency condition for search economies. Second, we consider a related economy in which there is a transaction role for money. In the absence of menu costs, the Friedman rule is optimal. In the presence of menu costs, the optimal inflation rate is negative for our numerical examples provided menu costs are small. A deviation from the Friedman rule can be optimal depending on the extent of the search externalities.  相似文献
