Real estate investment trust (REIT) dividend policies and dividend announcement effects during the 2008–2009 liquidity crisis are examined. Multinomial logit results indicate that REITs with higher market leverage or lower market‐to‐book ratios are more likely to cut dividends, suspend dividends or pay elective stock dividends. These results imply that mitigating going‐concern risk is an important motive for REITs adjusting dividend policies during the crisis and support dividend catering theory where investor demand for dividends impacts corporate dividend policies. Moreover, REITs that cut or suspend dividends experience positive cumulative abnormal returns during the post‐announcement period after controlling for the potential influence from simultaneous funds from operation announcements. The positive market response over the post‐announcement period supports the notion that dividend decisions convey information to investors and is also consistent with the broad catering theory of dividend policy.  相似文献

Although smart cities are now the subject of a growing literature, there is a paucity of research which considers how smart city projects develop on the ground. This paper begins to address this concern by exploring the development of a transport application, MotionMap, within the MK:Smart smart city programme. MotionMap aims to provide city-wide real-time transport information services. It is being developed through an ongoing dialogue sparked by the interaction of lead users and prototypes of a smart transport app. We draw on insights from Strategic Niche Management and social practice theories to explore how ‘smart’ might be integrated within and potentially transform the plurality of mobility practices that exist in cities.  相似文献

This paper examines the relationship between the price for Canadian wheat and the price for U.S. wheat. While a great deal of the variation in the Canadian series can be attributed to oscillations in either the exchange rate or the U.S. price of wheat, changing technologies, shifting market power, the marketing strategies of major market participants, and domestic market conditions are also seen to play a role in the price determination process and should be considered when making longer-term forecasts. The fact that the most encompassing price linkage specifications identified in this study differ significanty from the specification in a number of forecasting models in use today should be a point of particular concern. Since many of the decision equations (area seeded, inputs purchased, etc.) in place in these models essentially are driven off the Canada U.S. price linkage equation, the observed misspecification may have a detrimental impact on all forecasted series. Les auteurs examinent les rapports existants entre les prix canadiens et les prix américains du blé. Si une grande portion de la variabilité observée dans la série de donnée canadienne peut s'expliquer par les taux de change ou par le prix américain du blé, l'évolution des techniques, les déplacements des marchés, les stratégies de commercialisation des grands intervenants commerciaux et les conditions du marché intérieur jouent apparemment aussi un rôle dans la formation des prix. Ces facteurs devraient done être pris en compte dans les prévisions à long terme. Le fait que les spécifications de liaisons de prix les plus complètes dégagées dans cette étude s'técartent significativement de celles en usage dans plusieurs modèles de prévision mérite qu'on s'y arrête. Comme un bon nombre d'équations de décision (superficies emblavées, agrofournitures, etc.) utilisées dans ces modèles s'éloignent de l'équation de liaison de prix canado-américaine, cet écart pourrait avoir un impact défavorable sur toutes les séries de prévisions.  相似文献

If security prices are fully revealing, then all public information should be reflected in prices, and unsophisticated traders may be able to learn how various types of information affect security valuation by observing prices. A series of laboratory asset markets was conducted to examine whether unsophisticated traders are able to learn to evaluate publicly released information by trading with and observing trades made by a sophisticated trader who knows the valuation implications of the information. We find that unsophisticated traders who participate in an asset market with a sophisticated trader show significant improvement in their ability to use public information on a subsequent price estimation task. Conversely, a control group consisting only of unsophisticated traders shows no improvement. We conclude that market prices convey the sophisticated trader’s private information in a manner that permits unsophisticated investors to learn the stock price implications of a public information release.  相似文献

A series of laboratory double auction experiments is conducted to examine whether the order of information releases affects market prices. Behavioral research on belief revision has shown that individuals are influenced by the order in which a series of information items is presented. The experiments are designed to provide a controlled investigation of whether order effects as displayed by individuals also can influence prices in a market setting where outcomes are not a simple aggregation of individual behavior. Significant evidence is found of a recency effect in the experimental asset markets.  相似文献

In the quest for building long-term successful brands, many marketers have become increasingly interested in how to create and foster successful communities of brand users. The appeal of such an approach to relationship marketing lies in the recognition that members of brand communities tend to exhibit favorable brand-related behaviors and intentions. Research examining the social influence and creation of such social relationships among admirers of a brand has revealed substantial insights about the social processes that underlie customers' involvement in brand communities. Curiously, the psychological underpinnings of a customer's perception of community with other users of the brand remain unexplored. We offer the perspective that the observable, core components of brand community outlined in previous research may represent markers of social brand communities, while psychological brand communities may be characterized by an unobservable, psychological sense of community that could precede, or even work in lieu of, social interaction.  相似文献

This paper reports the results of an experiment designed to investigate how mandatory audit firm rotation affects auditor–client negotiations. Drawing upon process theories of negotiation, we examine the strategies used by auditors and clients as well as the outcomes of their negotiations in alternative settings in which mandatory rotation is imposed or is not imposed. We posit that mandatory rotation changes (1) the dynamics of the audit market by increasing the number of clients who are in the market for a new auditor, and (2) the political costs to a client who switches auditors. These changes, in turn, alter the willingness of the auditor and the client to cooperate during negotiation. The results suggest that with mandatory rotation auditors adopt less cooperative negotiation strategies, producing asset values that are more in line with the auditor’s preferences than with the client’s preferences and more negotiation impasses.  相似文献
