The article reviews the extraordinary number of international ventures by major telecommunications organizations and explores problems for traditional national regulation that these global networks create. A theoretical model is defined that illustrates the adjustment process of different national policies to each other. The choice of various supra-national regulatory arrangements is shown to be affecting substantive policy. The article then discusses options for coordination and concludes that the concrete problems created by supra-national carriers do not justify the hidden cost of elaborate mechanisms of supra-national policy. Since such coordination has traditionally been used to prop up monopoly arrangements, a better approach for the foreseeable future is to encourage more national policy experimentation and focus less on international policy coordination. 相似文献

Recent advancements in electronic technology have made possible a viable alternative information delivery system in the form of Electronic Decision Aids (EDAs). However, consumers will only benefit from such technological innovations if they are perceived to be useful in facilitating the decision making process. The current study investigates the effects of type of EDA format (autonomous versus dominant) and provision of educational information on the perceived utility of information presented via an electronic decision aid. In addition, the relationships between these two dimensions and specific consumer characteristics, including product familiarity, computer familiarity, and locus of control, as well as product type (search versus experience goods) are systematically identified and evaluated. Results suggest that selection of an appropriate format depends upon the nature of the product being selected, while inclusion of educational information enhances perceived utility of the information in selecting both types of products.

Der wahrgenommene Nutzen von Informationen, die durch elektronische Entscheidungshilfen bereitgestellt werden: eine Verbraucherperspektive
Zusammenfassung Elektronische Entscheidungshilfen in Einzelhandelsgeschäften sind eine neuartige Form der produktbezogenen Verbraucherinformation, die durch neuere technologische Entwicklungen ermöglicht wurde. Ob diese Innovation bei Konsumenten Erfolg haben wird, dürfte wesentlich davon abhängen, wie nützlich sie für den Kaufentscheidungsprozess eingeschätzt wird.Der Beitrag berichtet über eine empirische Studie darüber, wie diese wahrgenommene Nützlichkeit abhängig ist von der Informationsform (unterschieden danach, ob der sich informierende Verbraucher den Informationsvorgang eigenständig kontrollieren und gestalten kann oder nicht) und davon, ob die Information auch Bestandteile umfasst, die die generelle Produktkenntnis erhöhen und dadurch zusätzliche aufklärende Wirkung erzielen können, oder nicht. Ausserdem wurde der Einfluss der Produktart sowie der Produktvertrautheit des Konsumenten und seiner Vertrautheit mit dem Computer analysiert. Die Ergebnisse wurden in Laboruntersuchungen gewonnen, bei denen es um die Wahl eines Fotoapparates und um die Wahl eines Arztes ging.Es zeigt sich, dass es von der Produktart abhängig ist, welche der beiden Informationsformen zweckmässiger ist, wogegen durchgängig gilt, dass zusätzliche aufklärende Informationsbestandteile die wahrgenommene Nützlichkeit von Informationen erhoehen.

DotCom Mania: The Rise and Fall of Internet Stock Prices 总被引:10,自引:1,他引:9
This paper explores a model based on agents with heterogenous beliefs facing short sales restrictions, and its explanation for the rise, persistence, and eventual fall of Internet stock prices. First, we document substantial short sale restrictions for Internet stocks. Second, using data on Internet holdings and block trades, we show a link between heterogeneity and price effects for Internet stocks. Third, arguing that lockup expirations are a loosening of the short sale constraint, we document average, long‐run excess returns as low as ?33 percent for Internet stocks postlockup. We link the Internet bubble burst to the unprecedented level of lockup expirations and insider selling. 相似文献

The study investigates the value of additional information on the response function to soil salinity of a given crop (potatoes), with regard to a stochastic long-run optimization model for utilization of saline water in a single-farm framework. The analysis provides a conceptual and methodological framework for investigating the expected value of sample information (evsi ), as well as an efficient tool for empirical application. Although a few approximations have been used, the results provide an estimate of evsi and indicate the need for additional information. 相似文献

Managerial discretion and the economic determinants of the disclosed volatility parameter for valuing ESOs 总被引:1,自引:0,他引:1
This study investigates the determinants of the expected stock-price volatility assumption that firms use in estimating ESO
values and thus option expense. We find that, consistent with the guidance of FAS 123, firms use both historical and implied
volatility in deriving the expected volatility parameter. We also find, however, that the importance of each of the two variables
in explaining disclosed volatility relates inversely to their values, which results in a reduction in expected volatility
and thus option value. This can be interpreted as managers opportunistically use the discretion in estimating expected volatility
afforded by FAS 123. Consistent with this, we find that managerial incentives or ability to understate option value play a
key role in this behavior. Since discretion in estimating expected volatility is common to both FAS 123 and 123(R), our analysis
has important implications for market participants as well as regulators.

While true underlying home values are expected to be randomly distributed, actual residential listing prices tend to be highly clustered. Particularly, more than 75 % of the homes in our sample are associated with a round or “just below” round asking price. This study provides a theoretical and empirical examination of how the thousands digit in a home’s asking price is related to the final transaction price relative to its true underlying value. Our findings suggest that, on average, homes listed using a “just below” pricing strategy are associated with the greatest discount negotiated relative to the asking price. However, the higher initial degree of list overpricing reflected in “just below” pricing compared with other strategies more than offsets the greater discount. Therefore, “just below” is the most effective pricing strategy for the seller in terms of a greater dollar yield relative to value. These empirical findings have economic significance and are robust across both “buyer” and “seller” housing markets, new versus existing homes, and across multiple home price ranges. 相似文献

基于组合赋权和AHP法的农机化可持续发展研究 总被引:2,自引:0,他引:2
[目的]通过定量分析,明确不同准则层对农业机械化可持续发展的影响,衡量农机化可持续发展在时间维度上的演变趋势。[方法]建立了新疆农机化可持续发展评价指标体系,并构建了2001~2015年可持续发展水平评价指标关系数据模型。提出了组合赋权和专家法相结合的判断矩阵构建方法,并基于层次分析法(Analytic Hierarchy Process,AHP)分别定量分析了2001年和2015年农机化可持续发展状态。[结果](1)2015年新疆农机化可持续发展水平达到了80.31,和2001年相比提高了1.284 7倍。(2)从准则层来看,新疆可持续发展水平在农机化作业能力、农机化经济效益和农机化发展能力方面分别提高了69.70、85.94和48.64,但资源消耗方面的得分下降了1.12。[结论]2001~2005年新疆农业机械化可持续发展水平在作业能力、经济效益和发展能力等因素推动下进一步提升;揭示资源环境影响是约束农机化可持续发展的主要因素。从新疆农业机械化发展现状来看,文章方法得出的量化结果与实际情况较接近,表明研究方法有效和可行。 相似文献
