The demand for and supply of analysts’ opinions in this model yield an equilibrium that demonstrates how the information content of the opinions reacts to changes in exogenous parameters. The model also shows how changes in the parameters make analysts’ opinions more or less dispersed; for example, a decline in investor risk aversion, a decrease in market volatility, and an increase in information costs can lead to analysts’ opinions becoming more similar. Recognizing how exogenous factors can affect the supply and demand of analysts’ opinions gives additional insights into questions concerning what may appear to be herd behavior by analysts and also the relationship between forecast dispersion and information content.

This paper reports on a questionnaire survey about share valuation practices among investors and their intermediaries in Saudi Arabia. The findings suggest that fundamental analysis is used most by investor respondents where a P/E multiple is applied to an earnings forecast to generate a prediction of future price. However, technical analysis is also used to a much greater extent than in developed markets. Finally, the results indicate that quarterly and annual reports as well as newspapers are widely consulted by investors when forming their expectations about share valuations.  相似文献

This paper examines the welfare implications of alternative inflation targeting proposals for the monetary policy of the European Central Bank. We assume that policy makers have to “learn” the laws of motion of inflation in an economy characterized by “stickiness” in domestic price setting behavior and subjected to recurring shocks to productivity, exports and foreign price. We find that a switch from an “asymmetric” inflation targeting strategy to an “symmetric” makes little difference in welfare payoffs, but it comes at a cost of much higher interest-rate variability. We also find that there are practically no welfare gains from switching from an inflation-targeting strategy based on the Harmonized Index of Consumer Prices (HICP) to a strategy based on the domestic price component of the HICP.  相似文献

In the presence of foreign factor ownership tariffs change not only the terms of (goods) trade but also income flows between countries. Assume that only the home country owns factors abroad. Then the optimal tariff is negative if and only if foreign factor ownership entails trade-pattern reversals. Trade-pattern reversals are neither a necessary nor a sufficient condition for a negative optimal tariff if the foreign country owns factors in the home country. Changes in the home country's tariff shift the foreign country's offer curve. This adds a new dimension to optimal tariff analysis.  相似文献

The channel literature has paid little attention to issues related to exclusive dealing governance arrangements. Consequently, there is only limited knowledge about how exclusive dealing impacts various channel processes and outcomes. This gap is especially regrettable since exclusive dealing, in addition to being one of the most commonplace governance formats within the distribution channels, is also one of the best exemplars of viable unilateral governance formats. In this initial investigation, the authors explore the linkages among the constructs of exclusive dealing, relationalism, communication, and performance. Empirical data for the study were drawn from the photocopier industry. He obtained his M.B.A. and D.B.A. degrees from Boston University. His primary research interest includes channels of distribution, franchisor-franchisee relationships, and consumer purchase behavior in international contexts. He has published articles inJournal of Marketing Channels and the proceedings of several marketing conferences. This article was crafted when Rajiv Dant was at Boston University. He received his M.B.A. from Bombay University and his Ph.D. from Virginia Polytechnic Institute and State University. His research focuses on channels of distribution, with primary emphasis on franchise structure, franchisee-franchisor relationships, and public policy aspects of franchising growth and ownership topics. His research has been published inJournal of Marketing, Journal of Public Policy & Marketing, Research in Marketing, Journal of Retailing, Journal of Business Research, Journal of Business Venturing, Journal of the Operations Research Society, Marketing Letters, Journal of Small Business Management, Journal of Economic Psychology, Southern Business & Economics Journal, Philosophical and Radical Thought in Marketing, Journal of Healthcare Marketing, Journal of Marketing Channels, andInternational Small Business Journal.  相似文献

We provide a framework in which we link the valuation and assetallocation policies of defined benefits plans with the lifetimemarginal productivity schedule of the worker and the pensionplan formula. In turn, we examine the retirement policies thatare implied by the primitives of the model and the value ofpension obligations. Our model provides an explicit valuationformula for a stylized defined benefits plan. The optimal assetallocation policies consist of the replicating portfolio independentof the pension liabilities. We show that the worker with retirewhen the ratio of pension benefits to current wages reachesa critical value which depends on the parameters of the pensionplan and the discount rate. Using numerical techniques we analyzethe feedback effect of retirement policies on the valuationof plans and on the asset allocation decisions.  相似文献
