Over the past decade, multichannel, multimedia retailing environments have grown in variety, scope, and sophistication. However, research regarding the implications of this trend for consumer behavior is rather scarce. We seek to address this need by providing a comprehensive yet flexible approach for formulating promising consumer behavior-related research questions based in multichannel, multimedia retailing environments. This approach adopts a consumer-centric view of multichannel, multimedia retailing and identifies a number of important dimensions of this environment. We then illustrate how this approach could be applied via specific examples involving consumer memory, product assortment, and information acquisition. We conclude by considering the managerial implications of our proposed approach.  相似文献

We empirically identifysuperior analysts using their past forecasting track record fora specific firm's earnings and demonstrate that subsequent forecastannouncements by these superior analysts have a greater impacton security prices than do the forecasts of other analysts. Wefind that, in our sample, the price effects of this firm-specificforecasting ability do not spill over to other firms followedby the same analyst. We also demonstrate that an analyst's forecastingability with respect to the earnings of a certain firm is relativelymore important in the period immediately preceding an earningsannouncement by that firm.  相似文献

This paper concerns a procedure jor measuring the major economic risks and returns involved in forage production. Conventional static production economics was modified to permit the use of decision criteria under conditions of weather risk. Twenty-six years of rainfall data were analyzed to determine the expected mean number of days available for fieldwork ivithin each of three specified seasons. These seasons correspond with three critical forage production periods: e.g., (1) land preparation and planting, (2) hay harvest, and (3) corn silage harvest and fall plouiing. A probability distribution of days available for field operations was derived, and the number of days available in any one year was randomly selected from this distribution. Given the acreage involved and the machinery system, the days required to perform nine specified field operations were calculated. If the number of days required within a specified season exceeded the number of days available, the value of the crops produced was reduced by a set of yield reducing functions for each deficient day. Overhead and use-associated machinery costs uiere calculated, and net returns over machinery costs were determined for five machinery systems at 75,150, 225, and 300 acres. Cette publication montre une façon de mesurer les plus grands risques économiques et les profits provenant de la production fourragére. On a modifyé?économie de production conventionnelle et statique afin de tenir compte des critéres de décision utilisés sous les conditions de risques climatologiques. Les chutes de pluie ont été analysées sur une période de vingt-six ans afin de determiner la moyenne des jours disponibles au travail des champs, et ce, pour chacune des trois saisons specifiées. Ces saisons correspondent aux trois périodes critiques de la production fourragere: (1) la préparation du sol et le semis, (2) la récolte du foin, et (3) la récolte du maïs à ensiler et les labours ?automne. On a calculé la distribution probable des jours disponibles pour les travaux des champs et, de cette distribution, le nombre des jours disponibles fut choisi au hasard dans une quel-conque année. Selon une superfécie et un systéme dé machinerie determineés, le nombre de jours nécessaires à?exécution de neuf operations differéntes fut calculé. Lorsque le nombre de jour requis pour ?exécution des travaux ?une saison donnee dépasse le nombre de jours disponibles, la valeur des récoltes produites est réduite par une diminution de rende-ment de plusieurs facteurs, une diminution fonction du nombre de jours manquants. Les frais géneraux et les dépenses associées à?utilisation de la machinerie furent calculés. Les profits nets sur les dépenses de machinerie ont été déterminés pour chaque systéme ?equipement avec 75, 150, 225, et 300 âcres.  相似文献

This paper explores the significance of Potts’s (2000) claim that the key difference between orthodox and heterodox economics lies in the former viewing the economy as a mathematical field in which everything is connected to everything else, and the latter viewing it as a complex system in which only some elements are connected. It focuses on the types of connections in economic systems that different economists have identified and the significance of the degree of connectivity for how economic systems function. Topics explored include separable consumer networks, separable utility functions, checklist-based decision rules, lifestyles, goodwill, the nature of business strategies and evolution.  相似文献

Since merger and acquisition activity does not unambiguously benefit the shareholders of acquiring firms, the motivation of managers who undertake such actions is unclear. The present study investigates the extent to which the wealth effects of acquisition activity undertaken by firms in one industry—communications and publishing—are related to (1) the ownership and wealth characteristics of both the executives and the board of directors of these firms and (2) the ownership concentration of large outside shareholders. The motivating hypothesis, supported by empirical results, is that these factors contribute to the alignment of executive and shareholder interests.  相似文献

This paper develops a neoclassical model in which the behavior of the money supply affects investment by affecting the real distribution of asset returns. Investment depends on wealthholders' demand for capital. A stochastic money growth rule influences portfolio choice by affecting the distribution of the inflation rate. The variance of inflation matters to wealthholders because of the existence of assets with returns that are not indexed to changes in the price level: money and bonds which are contracted in nominal terms. In a rational expectations environment, asset demands will thus be sensitive to the distribution of the money growth rate. Our principle conclusion is that an increase in the variance of the money growth rate lowers investment, which complements Tobin's (1965) result that an increase in the mean stimulates capital accumulation. The paper also represents a step toward incorporating an asset market into a macroeconomic model in a manner which takes account of Lucas' (1976) criticism of econometric policy evaluation. All variables in the model, including asset return distributions, are functions of technology, preferences and the money supply rule. Further, expectations are rational.  相似文献

Kemp and Wan (1976) proved that nations forming a customs union can always compensate each other so that no nation will be worse off, relative to the pre-union equilibrium. Their proof, however, is existential, giving no clue how to construct such compensation schemes. This paper proposes a particular compensation scheme which is always feasible. Further, there are circumstances where this scheme is the only feasible one. At world prices the arrangement breaks even for each nation. At post-union internal prices, member compensations sum to the union's tariff receipts. The proof that such a scheme is feasible depends upon the Grandmont McFadden theorem.  相似文献
