In this paper, we consider the inventory decisions of two retailers who are supplied by a single supplier with uncertain capacity. When capacity is allocated in proportion to the retailers׳ orders, the retailers compete for the capacity by inflating their orders (i.e., the rationing game). In addition, we allow the retailers to implement transshipment between them such that they cooperate by transshipping the surplus stock of one to another who is out of stock. Our analysis of Nash equilibrium orders shows that, while order inflation in the equilibrium orders persists in the rationing game with transshipment, it may not occur if the amount of capacity shortage is small and the transshipment prices are low. Thus, carefully chosen transshipment prices may alleviate order inflation behavior. We also characterize centralized orders that maximize the total profit of the retailers and compare them to equilibrium orders. In particular, we investigate coordinating transshipment prices that induce the retailers to choose centralized orders. Our numerical analysis shows that, even for two identical retailers, coordinating transshipment prices exist in a more limited range of parameter values in the rationing game than they do outside the rationing game due to capacity uncertainty and limitation. 相似文献

Games and toys are irreplaceable basic needs of children of almost every age. They are also some of the most significant traces of culture. Some of our games and toys lost their original functions, and it is not remembered why they were functionally significant in Turkish Cypriot culture. Families and cultural identity also play a major role regarding different factors leading to changes in toy selection. The purpose of this study is to explore the knowledge and opinions of families regarding games and, in particular, toy selection for 6–12 year old children of Turkish Cypriot families. A survey was administered to 100 households in North Cyprus, and was used as a data collection tool. It was found that the most important factors in the selection of children’s games and toys were (1) the economic opportunities, and (2) children’s desires for toys after seeing them with their friends. A considerable number of families in Northern Cyprus see game-toy selection as important in a child’s social, psychomotor, mental, and cultural construction. Families, especially those living with difficulties, indicated that they cannot afford enough time to encourage playing traditional games. Although new versions of traditional games and toys are being developed and used, it is seen that educated and high-income families are more conscious about the importance of having information about them than others. 相似文献

The implementation of the government supervision of the quality of the project is an international practice. The basic form of government supervision of engineering quality is government supervision on the quality behavior of the engineering main bodies and its results by the competent government department entrusted. Its essence is a dual principal-agent process. The frequent accidents of the engineering quality reflect the loss and failure of the government law enforcement supervision of the engineering quality to some extent. Its root lies in the lack of endogenous power in the law enforcement supervision of the project quality government supervisors in the law enforcement supervision. Therefore, the incentive coordination mechanism of the government supervision based on the multi-level interest distribution is worth explored. In views of the multi-level management system which is formed by the government departments, government quality supervision organizations, quality supervision team (or group) for the government supervision of engineering quality. The benefit distribution function between every party is constructed, and the game model of the multi-level incentive and coordination for the government supervision in engineering quality is built. To solve and deduce from the first stage of the cooperative game and the second stage of the non-cooperative game, the cooperative game can obtain the reward coefficient: . The coordination degree of the best effort can be obtained by the non cooperative game. The result shows that:the coordination degree of government engineering quality supervisor is related to the coordination costs, and had nothing to do with fixed costs. The benefit distribution coefficient not only depends on the efforts of the quality government monitors, but also on the efficiency of other parties' efforts. The quality supervisors of the project will also focus on the coordination with other parties when enhancing their management capabilities to improve the overall performance of project quality government supervision. The strategy of the incentive coordination mechanism for the supervision and cooperation of the project quality government is:the government quality supervision team should set up the supervisory team properly, improve the coordination efficiency and reduce the cost of supervision-coordination to maximize the value of self-motivation. Quality supervision team (or group) should establish the partnership to improve the coordination efficiency for achieving the maximization of their own incentive value.The model and conclusion of incentive synergy mechanism based on multi-level benefit allocation mechanism are researched. It can provide theoretical support and practice reference for the market governance and supervision of general public goods. 相似文献

Using data from a large representative US sample (N = 1519), we compare hypothetical moral fairness values from the Moral Foundations Sacredness Scale with actual fairness behavior in an incentivized dictator game with either low or high stakes. We find that people with high moral fairness values fail to live up to their high fairness standards, when stake size increases. This violates principles from consistency theories according to which moral values are supposedly aligned with moral behavior, but is in line with temptation theories that question the absoluteness of morality values. 相似文献

儿童文学的"游戏精神"主要是指在儿童作品文本中体现出的、通过人物游戏所传递的一种符合儿童心理需求和审美旨趣,并实现儿童内心愿望的精神。周作人认为儿童文学的游戏精神是"幻想精神""愉悦精神"和"自由精神"。儿童文学游戏精神具有快乐性、幻想性和自由性的三性特征"。游戏精神"在儿童文学中作品的主要呈现形式为:通过"顽童""小大人""、反派"等人物形象的塑造凸显游戏精神;通过故事情节蕴涵的笨拙与聪明、嬉笑与吵闹、虚拟与真实凸显游戏精神;通过语言夸张凸显荒诞美、语言颠倒凸显逆向思维、语言突转凸显惊奇,从而凸显游戏精神。游戏精神对于儿童文学作品编创的意义在于:游戏精神是儿童文学的基本属性和内涵所在,新媒介时代儿童文学的发展需要延续游戏精神。因此游戏精神是儿童文学的作品编创的重要依据和准则。 相似文献

We demonstrate that personality has a systematic effect on strategic behavior. We focus on two personality traits: anxiousness and aggressiveness, and consider a 2-player entry game, where each player can guarantee a payoff by staying out, a higher payoff if she is the only player to enter, but a lower payoff if both players enter. We find that: anxious players enter less; aggressive players enter more; players are more likely to enter against anxious than non-anxious players; and players are less likely to enter against aggressive than non-aggressive players. We discuss the possible mechanism through which personality affects strategic behavior. 相似文献

We propose a methodology, called defender–attacker decision tree analysis, to evaluate defensive actions against terrorist attacks in a dynamic and hostile environment. Like most game‐theoretic formulations of this problem, we assume that the defenders act rationally by maximizing their expected utility or minimizing their expected costs. However, we do not assume that attackers maximize their expected utilities. Instead, we encode the defender's limited knowledge about the attacker's motivations and capabilities as a conditional probability distribution over the attacker's decisions. We apply this methodology to the problem of defending against possible terrorist attacks on commercial airplanes, using one of three weapons: infrared‐guided MANPADS (man‐portable air defense systems), laser‐guided MANPADS, or visually targeted RPGs (rocket propelled grenades). We also evaluate three countermeasures against these weapons: DIRCMs (directional infrared countermeasures), perimeter control around the airport, and hardening airplanes. The model includes deterrence effects, the effectiveness of the countermeasures, and the substitution of weapons and targets once a specific countermeasure is selected. It also includes a second stage of defensive decisions after an attack occurs. Key findings are: (1) due to the high cost of the countermeasures, not implementing countermeasures is the preferred defensive alternative for a large range of parameters; (2) if the probability of an attack and the associated consequences are large, a combination of DIRCMs and ground perimeter control are preferred over any single countermeasure. 相似文献
