Securing sales to a large buyer can be pivotal to a supplier's decision to produce. While conventional wisdom suggests that being pivotal improves a buyer's bargaining position, the opposite is shown in a multilateral bargaining model. If other buyers' payments fall short of costs, a pivotal buyer must cover the shortfall or forfeit consumption. This affords leverage that the supplier lacks when bargaining with non-pivotal buyers. The analysis illuminates contracting in markets with high fixed costs, such as cable television programming, motion pictures, and large-scale project finance, and has implications for the FCC's horizontal ownership limits on cable system operators.  相似文献

This paper gives a tree-based method for pricing American options in models where the stock price follows a general exponential Lévy process. A multinomial model for approximating the stock price process, which can be viewed as generalizing the binomial model of Cox, Ross, and Rubinstein (1979) for geometric Brownian motion, is developed. Under mild conditions, it is proved that the stock price process and the prices of American-type options on the stock, calculated from the multinomial model, converge to the corresponding prices under the continuous time Lévy process model. Explicit illustrations are given for the variance gamma model and the normal inverse Gaussian process when the option is an American put, but the procedure is applicable to a much wider class of derivatives including some path-dependent options. Our approach overcomes some practical difficulties that have previously been encountered when the Lévy process has infinite activity.  相似文献

An Internet presence is a critical early component in the process of building towards a fully operational and unified e‐commerce strategy. E‐commerce has significantly impacted logistics/supply chain strategies and the development and implementation of a website have become key issues for many firms within the transportation industry. This study provides an overview of website content within the motor carrier industry. Content analysis was used to assess the site design, informational content, and the interactive content of 152 motor carrier websites, and to compare the features offered on the Top 100 motor carrier firm websites with those offered on the sites of smaller carrier firms.  相似文献

Bringing knowledge management to practice one typically has to focus on concrete problems that exist in the daily work of the knowledge worker. We consider the task of tracking relevant information on the Web as important and time consuming, and thus as a concrete problem. In this paper we introduce an integrated approach for Web information tracking using ontologies. The overall approach has been implemented within a case study carried out at DaimlerChrysler AG.

The Worker Adjustment and Retraining Notification (WARN) Act of 1989 mandated that at least 60 days advance notice be given to employees. Critics argued that its passage would decrease managerial flexibility in closing plants, subsequently reducing firm values. This study addresses this issue by examining the stock market's reaction to announcements leading to the eventual enactment of the WARN legislation. We find evidence indicating negative effects of the legislation on stock returns of small firms.  相似文献

Saez-Marti and Weibull (J. Econom. Theory 86 (1999) 268) investigate the consequences of letting some agents play a myopic best reply to the myopic best reply in Young's (J. Econom. Theory 59 (1993) 145) bargaining model, which is how they introduce “cleverness” of players. I analyze such clever agents in general finite two-player games and show Young's (Individual Strategy and Social Structure, Princeton University Press, Princeton, NJ, 1998) prediction to be robust: adaptive learning with clever agents does select the same minimal curb set as in the absence of clever agents, if their population share is less than one. However, the long-run strategy distribution in such a curb set may vary with the share of clever agents.  相似文献

The determination of interconnection charges to essential facilities is an important problem in regulated telecommunications markets in the wake of the Telecommunications Act of 1996. This paper defines mathematical conditions for the essentiality of upstream productive inputs and examines their implications for efficient interconnection pricing. The paper shows conditions under which the efficient component-pricing rule (ECPR) can be derived as a special case of a Ramsey pricing rule. The paper also shows how efficient pricing differs from the ECPR for a number of interesting cases.  相似文献

Abstract

Although research has investigated the consequences of underemployment in domestic settings, research on the effects of underemployment among expatriates remains limited and has yielded inconsistent results. From a theoretical perspective, there is a need for a better understanding of the mechanisms through which underemployment affects various work-related outcomes and to account for potential contingencies. Drawing on the person-job fit literature and research on organizational identification, we theorise and empirically examine how and under what conditions underemployment influences expatriate performance. Using an original primary data-set of 103 Japanese expatriate managers in the UK, we find that underemployment affects expatriate work outcomes by increasing expatriates’ maladjustment and that this effect is moderated by the level to which expatriates identify with their organization.  相似文献
