This paper reexamines the determinants of the number of analysts following a firm using econometric models based on count distributions. We replicate Bhushan's (1989) analyst-following study to demonstrate the effects of using count-data econometrics, in lieu of OLS, in studying phenomena where the dependent variable ranges among nonnegative integers. In contrast with the original paper, our findings indicate the number of institutional investors is inversely related with analyst following. We also provide econometric evidence to support the preferred use of the negative binomial model in estimating cross-sectional, analyst-following regressions.  相似文献

This article investigates the ability of neural network models to predict mispricing of initial public offerings (IPOs). The aim is to improve the modest explanatory power of existing models that are based on the theory of asymmetrically informed economic agents surrounding post‐issue market value of IPOs. This study develops and compares linear regression and neural network models. The results show that modelling variable interactions and non‐linearity allows a potentially fruitful approach for stagging in IPOs. Neural networks have been criticized for being a black box; however, this paper shows that, by using sensitivity analysis, neural networks can provide a reasonable explanation of their predictive behaviour and direction of association between variables.

This paper reports results from a study of the economic value of the conservation benefits of Environmentally Sensitive Areas (ESAs) in Scotland. The main novelty of the approach taken is in comparing two direct valuation methods, namely contingent valuation and choice experiments, to value these benefits. The Contingent Valuation Method (CVM) is well-established as a technique for valuing the sorts of landscape and wildlife enhancements associated with ESAs. The CVM experiment reported here uses a dichotomous choice format, and includes a new correction for part-whole bias. Choice experiments are much less used as an environmental valuation technique. We note several advantages of such experiments over CVM, and then report characteristic values and ‘programme values’ estimated using the method. This application brings to light some problems in applying the choice experiment method. Finally, we discuss the issue of benefits transfer in the context of these two approaches to valuation.  相似文献

Public services in the UK are increasingly expected to account for their outputs and performance. This article describes a retrospective evaluation of the benefits from the R&D funded by a regional office of the NHS Executive. The methods adopted enabled the various elements of the region's R&D portfolio to be examined and provided a basis for the development of a plan for regular monitoring. The proposals for implementation are now also feeding into a debate as to how health services R&D might best be monitored nationally in a way that is compatible with the norms and practices of research in other contexts.  相似文献

Income smoothing, as defined in Statistical Activity Cost Theory (SACT), is the rational statistical adjustment of periodic accounting earnings to reduce their time volatility around average long-term profit per period. This article demonstrates how overhead cost allocations can be applied to smooth accounting earnings optimally in accordance with this definition. Such an approach parallels earlier work, such as that by Lane and Willett (1997 , 1999 ), in which a depreciation formula was derived and applied for this purpose. In particular, it is shown that, to realize an income smoothing effect in profit making firms, the usual optimal strategy is to over-allocate costs, giving support to the accounting principle of conservatism.  相似文献

Eco-efficiency refers to a process that seeks to maximize the effectiveness of business processes while minimizing their impacts on the environment. Fundamental to eco-efficiency is adoption of a management philosophy that stimulates the search for environmental improvements that yield parallel economic benefits [President’s Council on Sustainable Development, 1996a. Sustainable America: A New Consensus for Prosperity, Opportunity, and a Healthy Environment. Government Printing Office, Washington DC; President’s Council on Sustainable Development, 1996b. Eco-efficiency: Task Force Report. Government Printing Office, Washington DC; World Business Council for Sustainable Development (WBCSD), 2000. Eco-efficiency: Creating More Value with Less Input. Geneva]. Eco-efficiency is increased by activities that create economic value while continuously reducing ecological impacts and the use of natural resources [DeSimone, L., Popoff, F., 1997. Eco-efficiency: The Business Link To Sustainable Development. MIT Press, Cambridge, MA]. This study empirically examines the proposition that implementation of eco-efficient business strategies is associated with higher firm value. We posit that, firms which adopt eco-efficient business strategies and, as a consequence, achieve reduced costs and increased profits should be more highly valued by the market than similar firms that do not adopt eco-efficient business strategies. Our empirical testing supports this proposition.  相似文献

The Global Entrepreneurship Monitor research program was designed as a comprehensive assessment of the role of entrepreneurship in national economic growth. The conceptual model reflected in a wide range of factors associated with national variations in entrepreneurial activity and the major contextual features. Empirical tests of the many relationships in the model required four major data collection activities: adult population surveys, unstructured interviews with national experts, self-administered questionnaires completed by national experts, and assembly of relevant standardized measures from existing cross-national data sets. Adult population surveys were implemented to identify those entrepreneurially active, which required a set of precise criteria and careful processing to ensure harmonized counts and prevalence rates across 41 countries. Existing evidence on measures of reliability indicates that the measures met contemporary standards and the project was cost-effective.  相似文献

Whether it is called reengineering, quality function deployment, quality circles, continuous improvement or total quality management, business process redesign (BPR) is occurring in many organizations. In the broadest sense, BPR includes nearly any kind of systematic effort by companies to realign their business processes so that they are more competitive. Successful business process redesign can lead to dramatic improvements in productivity and quality. But BPR typically requires vast amounts of time and money to implement, since extensive employee input is necessary during the redesign process. Group Decision Support Software (GDSS) provides a viable alternative to the traditional BPR approach. GDSS is defined as computer-based information systems used to support intelligent, collaborative work.This technology allows multiple users to meet and discuss topics simultaneously via a computer network, thus increasing employee commitment while decreasing time and cost.This paper describes a business process redesign project that was conducted for a division within a large government agency fall of 1993. The BPR was done using a type of Group Decision Support Software called Group Systems V. A services marketing tool called service mapping was also used to identify customer needs and interfaces. Data were collected throughout the project to measure employee attitudes about the redesign process and the GroupSystems technology. Time to complete tasks was also recorded. The results of the study showed that the business process redesign was accomplished more effectively in a shorter period of time than with traditional BPR methods previously used. Participants also indicated that the service mapping tool provided a perspective that is missing from many BPR approaches: an understanding of the service from the customer's perspective.  相似文献

This paper focuses on the links between governance, firm capabilities and restructuring following the large-scale privatization process in Central and Eastern European transition economies using an integrative approach. Restructuring in these countries has been motivated by political and institutional changes and less so by market forces. Accordingly, political processes have produced political solutions such as “give-away” privatizations to insiders. These privatizations, in contrast to divestitures to outside owners, have realized less substantive restructuring because non-market incentives, such as too much managerial equity ownership, have created managerial entrenchment. In addition, we propose a connection between governance and organizational learning suggesting that learning is inhibited by excessive managerial ownership and lack of board knowledge regarding its oversight function. Furthermore, this entrenchment and poor board functioning may be perpetuated in financial-industrial groups, which have emerged as substitutes for market intermediaries in emerging economies. Thus, we propose that outside ownership involvement and the development of organizational capabilities may facilitate restructuring in the Central and Eastern European context. Our theoretical arguments are supported by case study evidence from transition economies.  相似文献
