This study examines the value relevance of mandated disclosures by UK firms of the investor‐firm share of liabilities of equity‐accounted associate and joint venture investees. It does so for the six years following the introduction of FRS 9: Associates and Joint Ventures, which forced a substantial increase in such disclosures by UK firms. Since the increased disclosure requirements were partly motivated by concern that single‐line equity accounting concealed the level of group gearing, and in light of previous US results, it is predicted that the mandated investee‐liability disclosures have a negative coefficient in a value‐relevance regression. The study also examines whether value‐relevance regression coefficients on investee‐liability disclosures are more negative for joint ventures than for associates and whether they are more negative in the presence of investor‐firm guarantees of investee‐firm obligations than in the absence of such guarantees. The study reports that the coefficient on all investee‐liability disclosures taken together has the predicted negative sign, and is significantly different from zero. It finds little evidence that the negative valuation impact of liability disclosures is stronger for joint venture investees overall than for associate investees overall, or stronger for guarantee cases overall than for non‐guarantee cases overall. There is, however, some evidence that the impact for joint venture guarantee cases is stronger than that for joint venture non‐guarantee cases and stronger than that for associate guarantee cases.  相似文献

The returns of hedge fund investors depend not only on the returns of the funds they hold but also on the timing and magnitude of their capital flows in and out of these funds. We use dollar-weighted returns (a form of Internal Rate of Return (IRR)) to assess the properties of actual investor returns on hedge funds and compare them to buy-and-hold fund returns. Our main finding is that annualized dollar-weighted returns are on the magnitude of 3% to 7% lower than corresponding buy-and-hold fund returns. Using factor models of risk and the estimated dollar-weighted performance gap, we find that the real alpha of hedge fund investors is close to zero. In absolute terms, dollar-weighted returns are reliably lower than the return on the Standard & Poor's (S&P) 500 index, and are only marginally higher than the risk-free rate as of the end of 2008. The combined impression from these results is that the return experience of hedge fund investors is much worse than previously thought.  相似文献

The authors recount their experience of the implementation of lean thinking and Six Sigma in pharmaceutical development research and development (R&D). Use of Lean Sigma in pharmaceutical manufacturing is widespread and generally noncontentious. Lean Sigma is used successfully to improve the development of new pharmaceutical manufacturing processes. However, the value of the application of lean and Six Sigma ideas to research & development is controversial. Published material is reviewed, and then the methods, tools, barriers and benefits are discussed, with recommendations for implementation of Lean Sigma into an R&D organisation.  相似文献

The relationship between organizational configurations and performance has been a frequent albeit controversial subject of research in the field of strategic management. Many studies have failed to find a link between configurations and performance, leading prominent researchers to question the value of the concept of organizational configurations. Before the concept can be discarded, however, other plausible explanations for the lack of findings should be examined. This paper examines the possible role of statistical power. Specifically, it may be that the sample sizes in many studies are too small to detect relationships between configurations and performance when such links are, in fact, present. Analysis of 24 tests of the configurations–performance link revealed that only 8 percent had samples large enough to detect all important relationships. Thus, there is reason to suspect that insufficient statistical power may help to explain extant results. Given these findings, suggestions are presented for improving the ability of configurational studies to detect relationships. Copyright © 1999 John Wiley & Sons, Ltd.  相似文献

Current Issues in the Analysis of Commercial Real Estate   总被引:1,自引:0,他引:1  
This paper identifies and discusses a number of current issues regarding our understanding of commercial real estate markets. These issues include: 1) accurate estimation of the quantity and location of our nation's commercial space; 2) an understanding of the linkage between the space and capital markets for commercial real estate; 3) identification of the macroeconomic factors that affect the rate of return on commercial property and whether local market factors also affect the rate of return; 4) problems associated with measuring the return characteristics of equity investments in commercial property (including measures of the diversification benefits and inflation-hedging abilities of this asset class); 5) a better understanding of rental markets, including good measures of changes in effective rents over time; and 6) examination of the rationale for ownership of commercial space by corporate users. This paper reviews recent research related to these questions and suggests future research that should prove to be fruitful.  相似文献

Freehand sketching is one of the most important and commonly used methods of generating and sharing budding ideas during the conceptual development portion of the preliminary phase of design. To develop one’s skills, prolonged practice, acquiring instant feedback and suggestions while practicing are invaluable. The two key and indispensable parts of learning draftsmanship are viewing and commenting on large numbers of free hand sketches. However, due to insufficient educational resources, instructors must spend most of their time engaged in class-room teaching, reducing the time allotted for one-on-one discussion and specialized assistance. Furthermore, the lack of sketch grading criteria can prevent students from developing proper insights into the essentials of sketching. As a result, students neither receive personalized feedback nor acquire adequate training in critiquing freehand sketching skills. These factors decrease learning effectiveness and negatively impact learning motivation. In order to solve this problem, this research has created a discussion platform on Facebook that utilizes the learning characteristics essential to developing proficiency in freehand sketching. It includes practice, observation, and comments. It has been found that this cultivates the subjects’ ability to judge freehand sketch quality and increases learning motivation and effectiveness through the process of peer-assessment. After participating in the one-semester teaching experiment, the abilities of the experimental group were significantly better than those of the control group, demonstrating that the online sketch discussion platform has a significant impact on freehand sketch learning.  相似文献

This paper assessed the effects of transactions costs—relative to price and non-price factors—on smallholder marketed surplus and input use in Kenya. A selectivity model was used that accounts for the effects of transactions costs, assets, technology, and support services in promoting input use and generating a marketable surplus. Output supply and input demand responses to changes in transactions costs and price and non-price factors were estimated and decomposed into market entry and intensity. The results showed that while transactions costs indeed have significant negative effects on market participation, institutional innovations—such as group marketing—are also emerging to mitigate the costs of accessing markets. Output price has no effect on output market entry and only provides incentives for increased supply by sellers. On the other hand, both price and non-price factors have significant influence on adoption and intensity of input use. Overall, the findings suggest that policy options are available other than price policies to promote input use and marketed surplus. The paper concludes with implications for policy to induce greater input–output market participation among smallholders in Africa.  相似文献

This study develops and tests predictions regarding factors that influence early‐stage CEO evaluation. We suggest that contextual elements of the CEO succession process will influence the heuristics that directors employ to aid in their early evaluation of a CEO because traditional performance metrics, such as firm performance, are less diagnostic of CEO quality in the first years of their tenure. Broad empirical support for our theoretical arguments is shown in a sample of Fortune 1000 firms. Copyright © 2012 John Wiley & Sons, Ltd.  相似文献
