In this study, we examine the effect of mutual fund connections, through managerial sharing, on performance and stock holding commonalities. Our analysis of return correlations and portfolio holdings indicates that more interconnected funds tend to buy and sell similar stocks, hence increasing the similarity of portfolio holdings and undermining the distinctiveness of their investment strategy. Our results also indicate that highly connected funds significantly underperform weakly connected funds by about 1.4% on a yearly risk‐adjusted basis. We show that fund family performance is unaffected by the intensity of fund connections, and that greater fund connections could significantly enhance family‐level profit margins. 相似文献

A critical but overlooked issue in Weick’s seminal work, The Social Psychology of Organizing (1969/1979), concerns ‘the heat’ of organizing processes, namely, the underground emotional processes underpinning the organizing of conflictual work relationships. We present a qualitative case study of psychiatric agencies mandated by public policy to collaborate but instead engaged in persistent conflict despite its deleterious effects on their working relationship and on the wellbeing of the clients they intended to serve. To explain these conflictual features of organizing, we integrate Weick’s organizing theory with systems psychodynamics to deepen the understanding of emotions in organizing, specifically the motivational forces underpinning sensemaking and actions between interacting psychiatric agencies. This integration of theories reveals a critical feature of the relationship between the conscious and unconscious organizing processes: When a threat is involved, sensemaking and action are overtaken by social defences, resulting in dysfunctional organizing of the primary task. Drawing on these findings, we enrich Weick’s seminal work by developing a model that portrays organizing as the ritualized interaction of emotions, sensemaking and behavioural responses. 相似文献

This research extends overlapping streams of research examining asymmetric information, adverse selection, and buyer trust by presenting an empirical investigation of the process by which a market for “lemons” emerges in the claiming market for thoroughbred racehorses. The study focuses attention on the potential of quality signals and buyer trust to lessen the impact of adverse selection. Incorporating concepts from economics, marketing, and psychology, a conceptual model suggests that adversely selected racehorses, distinguished by an unintentional signal from sellers to potential buyers, will be priced lower than otherwise similar racehorses perceived to be less subject to adverse selection. Data from one day of claiming races at 16 American racetracks (744 racehorses) are used to test this study hypothesis. Results provide evidence for adverse selection and a mitigating quality signal in the thoroughbred claiming market. Implications for buyers and sellers in this market, as well as more general implications, are discussed and an avenue for future research is proposed. 相似文献

The paper examines the economic impact of pricing and access to public basic research‐related intellectual property (IP) in the presence of downstream interfirm spillovers using a Salop circle model of monopolistic competition. Depending on the nature and extent of spillovers and with free access to upstream basic research, firm entry can be excessive, insufficient, or socially optimal. When interfirm lump‐sum spillovers are absent or sufficiently small, competitive entry is excessive, so policies that restrict access to basic research IP can enhance social welfare. When lump‐sum research spillovers are sufficiently large, policies to induce entry and a clustering of downstream research activity can be welfare enhancing. Le présent article examine, à l’aide du modèle de Salop de concurrence monopolistique positionnant les firmes sur un cercle, l’impact économique de l’attribution d’une valeur à la propriété intellectuelle de la recherche fondamentale financée par des fonds publics et de l’accès à cette recherche lorsqu’il y a des retombées entre firmes en aval. Selon la nature et l’étendue des retombées et compte tenu de l’accès gratuit à la recherche fondamentale en amont, l’entrée de firmes peut‐être excessive, insuffisante ou optimale sur le plan social. Lorsque les débordements de la recherche vers d’autres firmes sont absents ou faibles, le niveau d’entrée de concurrence parfaite est excessif. Dans ce cas, les politiques qui restreignent l’accès à la recherche fondamentale financée par des fonds publics peuvent accroître le bien‐être social. Lorsque les débordements de la recherche sont assez importants, les politiques mises en ?uvre pour encourager l’entrée et le regroupement des activités de recherche en amont peuvent améliorer le bien‐être. 相似文献

This article describes the context and methodology used in formulating and validating a senior-level human resource competency model for professional development. The development and implementation of the architecture for the model, including the provision of various developmental tools and experiences, was undertaken by the Society of Human Resource Management, a professional association dedicated to the advancement of the human resource profession. The purpose of this effort is to specify benchmarks for professional competence building and to reposition the emerging role and processes associated with the human resource function in responding to the changing organizational and competitive challenges facing United States-based, multinational organizations. © 1996 by John Wiley & Sons, Inc. 相似文献

Fresh Juice Incorporated (FJI) is in the process of determining whether it should launch a new fruit juice, Genetically Enhanced (GE) Juice. The GE Juice meets consumers' demands for a tasty, nutritious product and it would be the first new juice product in the last fifteen years. Before FJI decides to launch GE Juice, it must analyze the uncertainty surrounding market size, market share, and price of GE Juice. Finally, if FJI decides to launch GE Juice, then they must decide if they will bottle the juice themselves or outsource this process. This case teaches students how to discuss the strategic implications of launching a new product and develop a net present value and financial feasibility simulation model given limited information. 相似文献

Background: Tuberous sclerosis complex (TSC) is a multi-system genetic disorder in which renal manifestations occur in ~50% of children and 80% of adults. Since these often present alongside other manifestations, renal TSC is likely to incur significant costs. This study aims to quantify healthcare resource use (HCRU) and costs for renal TSC patients in the UK.Methods: TSC patients in the Clinical Practice Research Datalink (CPRD) linked to Hospital Episodes Statistics were identified from January 1987–June 2013. Clinical data were extracted over the entire history and costs were reported over the most recent 3-year period. HCRU was compared with a matched comparator cohort. Incremental costs were reported and the key cost drivers by primary manifestation category were identified by regression modeling.Results: A total of 79 renal TSC patients were identified with manifestations including chronic kidney disease stage 3–5 (with prevalence increasing with age) and renal angiomyolipoma. Renal TSC patients consistently reported greater HCRU than the comparator. Inpatient hospitalizations were more frequent for renal TSC patients (3.2 vs 1.6), but length of stay was comparable; however, 70.9% of renal TSC patients recorded no kidney-related procedures ever and averaged <1 test per year in the 3-year period. Average costs for renal TSC patients were nearly 3-fold greater than the comparator (£15,162 vs £5672). Costs increased with additional manifestation categories (£3600: only renal; £27,531: renal with ≥4 additional manifestation categories [25% of patients]). Additional nervous system and dermatology/psychiatric manifestations significantly (p?0.028) affected costs.Conclusions: Renal TSC patients have greater HCRU than the general CPRD population, likely to result from progression of renal disease and additional manifestations; however, surveillance for disease progression appears to be deficient. Inadequate monitoring may contribute to a lack of co-ordinated care and increased healthcare-associated costs. Efforts should be made to follow the TSC guidelines to effectively monitor and treat patients. 相似文献

The great concern exercised over the accuracy of estimates of the net direct investment position as a part of the U.S. international net worth is largely misplaced. By focusing on additions to the U.S. international net worth embodied in real assets owned in foreign countries, analysts divert attention from the large and growing volume of foreign-owned claims in private U.S. financial markets and the implications of those claims for instability in the foreign exchange market and for financial crisis. 相似文献
