Previous research finds that large companies previously judged to be excellent growth companies have subsequently been poor investments. We examine small companies selected by Business Week on the basis of multiple criteria used in annual articles featuring highly rated growth companies. We study the investment performance over the three years before eleven annual Business Week publications and the three years after publication. We find positive excess returns in the pre‐publication period, but negative excess returns in the post‐publication period. This reversal in investment performance appears to be due to a mean‐reversion tendency in operating performance, in which the earnings and the past rates of return on capital of such companies subsequently decrease significantly. 相似文献

This study investigates how participating in strategic alliances with rivals affects the relative competitive positions of the partner firms. The paper builds on studies that show significant differences in the outcomes of scale and link alliances. The study argues that the more asymmetric outcomes of link alliances translate into greater changes in the relative market shares of the partner firms, due to unbalanced opportunities for inter‐partner learning and learning by doing. We find support for this argument by examining 135 alliances among competing firms in the global automobile industry, from 1966 to 1995. Copyright © 2004 John Wiley & Sons, Ltd. 相似文献

Great variation in nursing resource use is documented within DRGs. Much of this variation may be explained by patient severity of illness. Variance in nursing resource use within DRGs can be reduced by using a severity of illness instrument to score patients. 相似文献

Annuity Values in Defined Contribution Retirement Systems: Australia and Singapore Compared 总被引:1,自引:0,他引:1
Annuities promise to play an increasingly important role in countries with national defined contribution retirement systems. In this article we examine life annuities in two countries, Singapore and Australia, each of which has a national mandatory pension program. Exploiting data on annuity pricing and purchase behaviour, we compare the money's worth of life annuity products across these two nations. Our results indicate that, after controlling on administrative loadings, there are important differences in measured adverse selection. Part of the explanation may be due to the different structures of the two countries’retirement systems. 相似文献

Characteristics of Risk and Return in Risk Arbitrage 总被引:5,自引:0,他引:5
This paper analyzes 4,750 mergers from 1963 to 1998 to characterize the risk and return in risk arbitrage. Results indicate that risk arbitrage returns are positively correlated with market returns in severely depreciating markets but uncorrelated with market returns in flat and appreciating markets. This suggests that returns to risk arbitrage are similar to those obtained from selling uncovered index put options. Using a contingent claims analysis that controls for the nonlinear relationship with market returns, and after controlling for transaction costs, we find that risk arbitrage generates excess returns of four percent per year. 相似文献

We study a dynamic duopoly model with network externalities. The value of the product depends on the current and past network size. We compare the market outcome to a planner. With equal quality products, the market outcome may result in too little standardization (i.e. too many products active in the long run) but never too much. The potential inefficiency is non-monotonic in the strength of the network effect, being most likely for intermediate levels. When products differ in quality, an inferior product may dominate even when the planner would choose otherwise, but only if the discount factor is sufficiently large 相似文献

The role of geographic distance in completing related acquisitions: Evidence from U.S. chemical manufacturers 下载免费PDF全文
Acquisitions often do not reach completion when buyers' initial evaluations change during post‐announcement due diligence investigations, but research offers only limited explanations for when such deal‐cancelling new information will be most common. Drawing from the spatial geography and acquisition strategy literatures, we argue that successful completion of acquisitions can be partially explained by their spatial characteristics. We start by predicting that geographic distance has a particularly strong impact in reducing the likelihood of completing related acquisitions; we then identify contingencies based on multiple forms of direct, contextual, and vicarious experience that can help acquirers overcome the constraints of distance. We test the arguments with a sample of 1,603 domestic acquisitions announced by 724 U.S. chemical manufacturing firms between 1980 and 2004. Copyright © 2015 John Wiley & Sons, Ltd. 相似文献

Lisle S. Mitchell 《Annals of Tourism Research》1979,6(3):235-244
The geography of tourism is limited by a dearth of published research in geographic journals, the relatively few individuals who actively participate in the sub-discipline, and the lack of prestige the subject matter specialty has in geography. Despite these imperfections geographers make important contributions to the study of tourism because of their unique point-of-view. This characteristic perspective is seen in the context of a conceptual frame-of-reference which consists of a matrix based on two trichotomies. An analysis and interpretation of this framework and its application to the nine substantive articles included in the special issue constitute a majority of the article. 相似文献

This article is the outcome of a continuing programme of research involving systems engineers and political scientists. The ultimate aim is to explore the relevance of some of the methodologies of systems engineering to problems in the social sciences, especially the dynamics of domestic and international conflict. An initial exercise in modelling domestic conflict in terms of state equations (system dynamics) is described, although the study reflects the authors' interest in several approaches by the broadly based survey of past work and proposed diversification of their research. 相似文献
