We test the hypothesis that the information content of dividend-change announcements, as reflected in stock prices, is directly related to the degree of pre-announcement information asymmetry in the stock. The dividend-change announcements include initiations, large increases, large decreases, and omissions. Information asymmetry is proxied by the proportion of stock held by institutions. Consistent with the hypothesis, we document a significantly positive relation between the absolute values of the announcement-period excess returns and the degree of pre-announcement information asymmetry in the stock. This finding appears to hold for all types of dividend changes except dividend omissions. 相似文献

Alba and Chattopadhyay (1985, 1986) have demonstrated that having consumers think about a familiar brand can interfere with the retrieval of competitive brand names, including those that might otherwise be considered for purchase. However, their research is silent about two issues of pragmatic importance. First, is it possible to inhibit retrieval of the consumer's preferred brand? Second, can an unfamiliar brand evoke recall inhibition? Our findings indicate that recall inhibition does not extend to the preferred brand. Our findings further suggest that recall inhibition can be induced by cueing consumers with an unfamiliar brand name, but that such inhibition is less pervasive than evoked by a highly familiar brand name. 相似文献

Our objective is to develop a unifying framework for the incorporation of different types of survey data in individual choice models. We describe statistical methodologies that combine multiple sources of data in the estimation of individual choice models and summarize the current state of the art of data combination methods that have been used with market research data. The most successful applications so far have combined revealed and stated preference data. We discuss different types of market and survey data and provide examples of research contexts in which one might wish to combine them. Although these methods show a great deal of promise and have already been used successfully in a number of applications, several important research issues remain. A discussion of these issues and directions for further research conclude the paper. 相似文献

This paper introduces new forms, sampling and estimation approaches fordiscrete choice models. The new models include behavioral specifications oflatent class choice models, multinomial probit, hybrid logit, andnon-parametric methods. Recent contributions also include new specializedchoice based sample designs that permit greater efficiency in datacollection. Finally, the paper describes recent developments in the use ofsimulation methods for model estimation. These developments are designed toallow the applications of discrete choice models to a wider variety ofdiscrete choice problems. 相似文献

The gap in total factor productivity in sawmills and wood preservation between the US and Canada generally increased from 1958 to 2005. The present paper examines the effects of the various phases of the softwood lumber dispute, including relatively free trade, Canadian export taxes, and low and high countervailing duties, on this productivity gap. Exogenous control variables include US housing demand, the exchange rate, softwood lumber prices, and ratios of capital and nonproduction labor to labor. The effects of phases of the dispute on US imports from Canada are also examined. 相似文献

由于美国是世界主要的温室气体排放上的重要国家,所以美国在应对气候变化上面的政策举措和立法备受瞩目。本文从多个角度全面的介绍了美国众议院于2009年6月通过的美国清洁能源与安全法案。着重反映了该法案的立法过程、主要内容、争议焦点以及各方对此法案的反响。并在此基础上,结合中国的目前的实际,总结美国在此立法上的得失,提出了中国可以借鉴的内容。同时也为中国将来采取何种减排措施作了分析,给出了相应的建议。 相似文献

This paper develops a model for situations in marketing and elsewhere in which an individual decision maker acquires multiattributed items that belong to several classes over time. The model captures the dynamic acquisition of heterogeneous items. Measurement and parameter estimation methods are described and illustrated with a small set of experiment data involving the acquisition of durable goods by households. Future research steps are also outlined. 相似文献
