Increasing public concerns about health risks associated with dietary intakes of cholesterol are expected to have significant impacts on the demand for foods with high fat content. This paper investigates how information about cholesterol, as measured by two newly constructed indices based on published medical research, has affected the demand for meats (beef, chicken and pork) and fish in the Nordic countries (Denmark, Finland, Norway and Sweden). To compare the effects of information across countries and over time, the demand equations for all the countries are estimated within one system, and a complete set of price and expenditure elasticities is estimated. Our findings suggest that health information has affected consumption in a healthy way in all countries studied except for Denmark. We find positive effects on the demand for chicken in Finland, Norway and Sweden and for fish in Finland and Sweden. A negative effect on the demand for beef in Sweden also is found. First version received: May 2001/Final version received: December 2001 RID="*" ID="*"  The authors would like to thank Wen S. Chern and Bj?rn Sl?en for their assistance in the construction of the health information indices. The suggestions of two anonymous referees have also been of great assistance. The EU (contract FAIRS-CT97-3373) and the Research Council of Norway (grant no. 134018/110) provided financial support for this research.”  相似文献

This article examines the relation between systematic price changes and the heterogeneity of investors information sets in real estate asset markets. The empirical implications rely on a theoretical economy in which information asymmetry alters the dynamic relation between returns and trading volume. We employ a filter-rule methodology to determine predictability in returns and augment the return-based conditioning set with trading volume. The additional conditioning information is necessary since the model is underspecified when predictability is based on returns alone. Our results provide new insight into the coexistence of informational and noninformational exchange in the speculative markets for real estate assets. Specifically, we find that the predictability of real estate returns is generally more indicative of portfolio rebalancing effects than an adverse-selection problem. These results are unique in addressing the time-variation in information asymmetry.  相似文献

The underwriter of an IPO has two sources of compensation for its services on behalf of the issuer. One is through a commission (spread), the other is by buying issued shares for itself (or its affiliates) and reselling them in the post-issue market. Profits from the former decrease along with the magnitude of underpricing while profits from the latter increase with it. Faced with these countervailing interests, the present paper analyzes how the underwriter decides upon the pricing and allocation of IPOs.   相似文献

This paper generalizes the informational environment of the Rock model to address empirical evidence and conjectures that cannot be addressed within the standard model based on informed and uninformed investors such as underpricing being positively related to market returns observed prior to the IPO, the number of IPOs being positively related to market returns, underpricing being partly predictable based on public information, and the return to uninformed participation being negative overall but positively related to market returns observed prior to the IPO. Finally, the model suggests that a positive relation between market returns and underpricing need not represent an inefficiency in the pricing of IPOs.  相似文献

This paper examines whether the use of non-financial information by sell-side financial analysts influences the accuracy of analysts’ forecasts. The research findings, based on a survey of Belgian financial analysts, suggest that financial analysts who use more forward-looking information and more internal-structure information offer more accurate forecasts. Furthermore, the listed Belgian firms examined in this study have improved their non-financial information reporting over time. However, neither the frequency nor the quantity of non-financial information mentioned by financial analysts in their reports appears to have increased over time.  相似文献

This paper responds to recent research by Ruland et al. [Ruland, W., Shon, J., Zhou, P., 2007. Effective controls for research in international accounting. Journal of Accounting and Public Policy, 26(1), 96–116.] that addresses the effectiveness of experimental controls for research in international accounting, with focus on Ndubizu and Sanchez [Ndubizu, G.A., Sanchez, M.H., 2006. The valuation properties of earnings and book value prepared under US GAAP in Chile and IAS in Peru. Journal of Accounting and Public Policy 25 (2)]. We attempt to remove some misconceptions about effective experimental controls that have surfaced in the debate. We argue that theory and refined proxies alleviate many of the control issues that have surfaced in the literature.  相似文献
