This article presents a classroom game that allows students to directly experience the welfare improvements that can result from price discrimination. The demonstration uses a very familiar decision-making scenario, campus parking, to introduce the concept of price discrimination as well as reinforce the concepts of opportunity cost, consumer surplus, and search costs. This game can be used in a variety of classes, including principles, intermediate theory, industrial organization, or environmental economics, and can be conducted in a 50-minute class period with follow-up discussion in the next class.  相似文献

Although upfront payments are often observed in contracts between manufacturers and retailers, little is known about their competitive effects or the role retailers play in securing them. In this article, we consider a model in which two competing retailers make take‐it‐or‐leave‐it offers to a common manufacturer. We find that upfront payments are a feature of equilibrium contracts, and in all equilibria, only one retailer buys from the manufacturer. These findings support the claims of small manufacturers who argue that they are often unable to obtain widespread distribution for their products because of upfront payments.  相似文献

This paper investigates the effects of performance based monetary incentives on cue usage within the information overload paradigm. Participants suggested appropriate stock prices for hypothetical companies based on either six or nine non-correlated information cues. The presence of monetary incentives motivated increased response times compared to participants who did not receive incentives. This in turn resulted in higher levels of information usage than has been observed in previous studies. The results support the view that information processing capacity imposes a limit on the amount of information processed per unit of time rather than on the amount of information that can be processed in total.  相似文献

Genetic improvement has been a major contributor to agricultural productivity in the United States, but many questions about the economics of crop breeding, such as the value of pre-commercial germplasm, remain unanswered. This study estimates the marginal value of poorly characterized materials contained in the U.S. national germplasm system. Within the search theoretic framework, we apply a maximum entropy method to estimate the probability and the expected level of improvement in pest susceptibility relative to its best previously observed level. The results indicate that the lower-bound estimate of benefit is significantly higher than the upper-bound cost of conserving an accession.  相似文献

Locating emergency medical services in small town and rural settings presents subtle, but significant differences to those in metropolitan areas. The lack of service mix and unit choice, the measurement of response time in minutes rather than seconds, and the limits of the planning environment are discussed. Using time-distance comparisons and location-allocation techniques within a microcomputing environment, some aspects of planning emergency medical services are illustrated within the context of the Kingston (Ontario) Regional Ambulance Service.  相似文献

Longitudinal data from the Panel Study of Income Dynamics and the German Socio-Economic Panel are used to show that women and children are worse off following a marital split than are men in both the United States and Germany. The size of the difference is sensitive to the equivalence scale used, but despite its far more extensive tax and transfer system the disparate impact of divorce or separation on women and children persisted in Germany at a level at least as high as in the United States.  相似文献
