考虑集成商营销努力的养老服务提供商服务质量激励研究

在考虑养老服务集成商营销努力的情况下,通过设计成本分担契约、收益共享契约激励养老服务提供商改善服务质量,分析了两类激励契约的适用条件;比较了对养老服务质量、营销水平决策和各成员利润的改善作用。研究结果表明：提供商的服务质量、利润会随着成本分担比例的增加而递增,随着收益共享比例的增加而递减;集成商的营销水平会随着成本分担比例的增加而增加,而随着收益共享比例的增加而递减,利润水平会随着成本分担比例和收益共享比例的增加而递减;需求影响系数对三种情境下的提供商和集成商利润产生正向作用,签订成本分担契约对提供商较为有利,集成商可能更倾向于收益共享契约;成本影响系数则对利润产生负向作用,签订收益共享契约对提供商较为有利,对于集成商来说,其利润在三种情境下的差异不大;成本分担契约对激励提供商改善服务质量和集成商提升营销水平具有最佳的激励作用。在大多数情况下,提供商获得的利润总是高于集成商。     

Optimal ownership in joint ventures with contributions of asymmetric partners

This paper addresses two questions concerning Joint Venture (JV) agreements. We first study the formation and the performance of a JV when the partners’ contribution has a different impact on the JV profits. Then, we check whether the JV is more likely as well as the welfare level improves when the decision on JV profit sharing among partners is delegated to an independent JV management (Management sharing) rather than jointly taken by partners (Coordinated sharing). We find that the firm whose effort has a higher impact on the JV’s profits should have a larger profit share. Moreover, at least in some cases, Management sharing increases both welfare and the probability that the JV is formed.      

WELFARE ENHANCING COORDINATION IN CONSUMER COOPERATIVES UNDER MIXED OLIGOPOLY

The recent globalization of world economies has led the retail markets of developed countries towards increasing levels of integration and strategic interdependence. A non negligible share of retail and food markets is currently served by co‐operative societies. Consistently with this trend, the consumer cooperatives have recently experienced increasing levels of integration. The main aim of this paper is to study the welfare effects of coordination among consumer cooperatives competing in quantities in a mixed oligopoly against profit‐maximizing firms. We show that, in absence of agency problems, under increasing or constant returns to scale a higher output coordination of the consumer cooperatives does not affect the total welfare as long as a nonnegative profit constraint holds in these firms. On the other hand, under decreasing returns to scale, the consumer cooperatives contribute more to social welfare when acting on behalf of all consumers. This is because, by coordinating consumers’ preferences, these firms can reduce their market output, thus helping the market to come closer to the first best. All together these results seem to provide an argument in favour of the recent process of integration involving consumer cooperatives in many developed countries.     

Demand disruption and coordination of supply chain via effort and revenue sharing

This article explores the equilibrium behaviour of a basic supplier–retailer distribution channel under demand disruption via effort and revenue sharing contract. This differs from the traditional supply chain coordination model. Firstly, demand is simultaneously affected by retail price and nonprice marketing effort from manufacturers and retailers. Secondly, when the demand is disrupted, this article considers disruptions in the market scale and price sensitivity coefficient. Thirdly, the supply chain coordination model is proposed via effort and revenue sharing contract. In this way, the manufacturer reduces the wholesale price as an incentive for the retailer to share revenue. Finally, the total supply chain profit is greater with contract than no contract. This also constitutes another incentive for the players to follow the effort and revenue sharing contract.     

产业链的合作机制选择与低碳产品定价及碳减排策略

生产链上下游企业选择合适的合作机制对低碳产品定价及碳减排有重要影响。通过构建博弈模型分析三种不同合作机制下的低碳产品定价及碳减排问题:第一种合作机制即制造商与零售商进行合作,当两条生产链都选择这种合作机制时,能带来较高的碳减排率和较低的零售价格,这对制造商、零售商、消费者和环境都是有利的。第二种合作机制即两条生产链的制造商之间、零售商之间分别合作,这会带来较低的碳减排率和较高的零售价格,对两个制造商有利,而对零售商和消费者不利。分析前两种合作机制的利与弊提出第三种合作机制,即零售商和制造商共享利润下的有利于碳减排的策略。最后,结合案例讨论和数值分析的研究结果表明:当制造商和零售商收入共享比在一定范围内时,第三种合作机制可以给制造商和零售商带来更高的利润。由此为企业选择最佳的合作机制及合理的碳减排策略提供了理论指导。     

The foreclosure argument for exclusive dealing: The case of differentiated retailers

I analyze a cooperative characteristic-form game between two differentiated producers and a downstream retail sector. When there is a single downstream retailer, the game always has a nonempty Core, involving the retailer being a common dealer. Each producer can at most earn his increment to the collusive industry profit. This result is similar to what is obtained in the literature in an extensive-form noncooperative formulation of the game. When there are two differentiated downstream retailers, the Core is empty when products and retailers are too homogeneous. For sufficient product and retailer differentiation, the Core is nonempty. In these cases the retailers are always common dealers for both products.     

A model of sliding-scale regulation

Price caps, while widely touted, are less commonly implemented. Most incentive schemes involve profit sharing and are, thus, variants of sliding-scale regulation. I show that, relative to price caps, some degree of profit sharing always increases expected welfare. Numerical simulations show that welfare may be enhanced by large amounts of profit sharing and by granting the firm a greater share of gains than of losses. Simulations also suggest profit sharing is most beneficial when the firm's initial cost is high and cost-reducing innovations are difficult to achieve but offer the potential for substantial savings.This paper has benefitted from the comments of Mark Bagnoli, Jim Burgess, Michael Crew, Steve Hackett, Paul Kleindorfer, Michael Riordan, Ted Stefos, Ingo Vogelsang, Dennis Weisman, two anonymous referees, and workshop participants at the First Annual Northeastern Health Economics Conference, the Fourth Annual Health Economics Conference, GTE, Indiana University, the Rutgers Advanced Workshop in Regulation and Public Utility Economics, and the 20th Telecommunications Policy Research Conference.

The role of mediation in peacemaking and peacekeeping negotiations

We develop a model of bargaining that provides a rationale for the difference in the method of negotiation, depending on the nature of the conflict. We distinguish those negotiations that take place previous to a potential conflict (peacekeeping), and negotiations inside the conflict (peacemaking). In these contexts, we study the role of a mediator who tries to achieve a certain balance between the efficiency of the agreement and the equality of the final sharing. We show that the credibility of the mediator comes from her willingness to impose delays in the negotiation, even if that implies costs. We also find how the player with a “weak” bargaining position in a conflict can strategically profit from the mediator's quest for equality. Finally, we show how the capacity of the mediator to induce a higher equality in the sharing is always higher in a peacemaking situation than in a peacekeeping one.     

The codetermined firm in a Cournot duopoly: A stability analysis

This paper aims to study the stability issue in a Cournot duopoly with codetermined firms. We show that when both firms codetermine employment together with decentralised employees' representatives, a rise in wages acts as an economic (de)stabiliser when the wage is fairly (high) low, while under profit maximisation a rise in wages always acts as a stabilising device because the parametric stability region monotonically increases with the wage in such a case. Moreover, a rise in the union's bargaining power has a de-stabilising effect, except when the wage is low and the firm power is already high. Therefore, under codetermination a change either in the wage or firm power in the Nash bargaining plays an ambiguous role on stability. We also show with numerical simulations that complex dynamics can also occur.     

Profit-sharing versus interest-taking in the Kaldor–Pasinetti theory of income and profit distribution

Abstract

This paper reformulates the Kaldor–Pasinetti model of income and profit distribution by introducing the interest rate from the very outset of the model but maintaining other Kaldor–Pasinetti assumptions intact. It is shown that the profit rate and the share of profits in national income are not independent from either the capitalists' or workers' propensity to save. Many contributors to the theory of income and profit distribution have erred in attributing a potentially positive impact of the interest rate upon profits. The interest rate is always and everywhere a tax on functional and personal incomes together. This result explains Schumpeter's observation that ‘Interest acts as a tax upon profit.’ In an alternative model, workers receive a share of profits instead of fixed contractual interest. It is shown that the profit rate and share are not independent from either propensity to save. Furthermore, the workers' share of profits has a positive impact on the rate and share of profits. This implies that a profit sharing regime could be more conducive to capital accumulation and job creation. It is found that Pasinetti's Cambridge Equation is more akin to a profit sharing regime.     

COLLUSION AND PREDATION UNDER THE CONDITION OF STOCHASTIC BANKRUPTCY

In this paper, on the basis of the framework of repeated games, we consider the strategic interaction between firms that may face financial constraints and go into bankruptcy when they earn low profit. We demonstrate that under asymmetric information concerning the financial constraints of the rival firm, firms adopt a pricing pattern wherein they switch to high (or collusive) prices after maintaining low prices for some periods. There are always such predatory pricing strategies sustained as equilibria when firms are sufficiently patient. We also show that the set of feasible and individual rational payoffs becomes narrower than that of the ordinal repeated games.

考虑保鲜努力的生鲜农产品零售商与物流服务商的协调合同

物流服务商提高生鲜农产品的保鲜努力水平会对零售商的利润产生重要影响。一般的物流合同不能有效鼓励物流服务商提高生鲜农产品的保鲜努力水平。为此,本文建立了一种成本分担与收入共享合同。该合同在不损害物流服务商利益的前提下,使物流服务商提高保鲜努力水平;同时,零售商分担部分保鲜努力成本,并分享部分销售收入给物流服务商。研究结果表明,这一合同可形成一种有效的内在激励机制,提高物流服务商对生鲜农产品的保鲜努力水平,最终实现系统利润的最大化、双方的共赢。     

The effect of subsidy policies on the product quality improvement

This paper analyzes the effect of government subsidy policies on creating an incentive for domestic firms to improve their product quality before exporting to an outside market. The goal of the government is to minimize the time it takes to reach the appropriate product quality level at low costs. We simulate a dynamic profit maximization problem of the firm and derive the optimal path of the product quality development, then test the efficiency of the three types of subsidy methods: Constant Subsidy, Quality Matching Subsidy and Time-limited Subsidy methods. Our model yields a number of intriguing results: (i) not every subsidy methods guarantee product quality development, although the same amount is subsidized. (ii) the matching fund style subsidy is more efficient than providing constant amount of subsidy. (iii) Time-limited Subsidy improves product quality faster than the unlimited subsidy method. (iv) Time-limited Subsidy improves quality much faster than other methods with less subsidy cost. (v) there is an optimal combination between the subsidy and the time limits.     

西方发达国家公司治理模式演进趋势分析

西方发达国家大体有两类迥然相异的公司治理模式:盎格鲁——萨克森模式和莱茵模式。20世纪80年代以来,两类公司治理模式呈现一些趋同的迹象,但由此推断公司治理模式将趋同缺乏足够的说服力。公司治理模式的实质趋同是不可能的。这一结论对我国企业构建治理模式具有重要启示。     

Productivity,earnings, and profit sharing — An econometric analysis of alternative models

The theoretical status of the relationship between productivity, wages, and profit sharing (PS) is poor. Only some alternative hypotheses can be formulated. From these explanations six different econometric models are derived. Using data of the German Socio-Economic Panel the models are estimated and tests and indicators are employed to choose the best model. Our investigation speaks in favour of hybrid simultaneous Tobit models where the level of profit sharing is positively correlated with productivity which induces positive wage effects on the one hand. But on the other hand the level of wages is also relevant to the question whether a firm introduces or decides to continuePS and which amount ofPS should be paid.What is obvious is not always true and introspection is a notoriously unreliable guide to empirical magnitudes.

Economic effects of positive credit information sharing: the case of Korea

In many countries, in addition to negative credit information such as loan default and arrears, positive credit information is also exchanged on a voluntary and reciprocal basis. Employing optimal credit decision models of profit maximizing banks, and utilizing a unique dataset of 2?million consumer loan obligors in Korea, we investigate the economic effects of sharing positive credit information in addition to negative credit information already exchanged. We find that the discriminatory power of the credit scoring model improves significantly. We proceed to investigate the economic effects of the information gap in a competitive credit market by assuming two representative banks that differ only in the level of credit information sharing. The bank that utilizes negative information only suffers from deterioration of the borrower pool and reduced profit, as high credit risk borrowers are more concentrated on this bank due to underpricing of risks. Our finding suggests that banks have incentives to voluntarily participate in the positive information sharing mechanism, since even a small difference in discriminatory power stemming from the information gap may lead to a significant fall in profitability as the distribution of borrower quality changes endogenously due to adverse selection problems.     

Simultaneous versus sequential knowledge transfer in an organization

This paper studies an organizational knowledge sharing process which requires costly “teaching” and “learning” efforts on the part of the sender and receiver, respectively. The process is a team problem in which the principal rewards successful sharing by optimally rewarding performance. In this setting we compare two modes of knowledge transfer with regard to efficiency. The first is sequential in which the sender precommits to teaching and the receiver acts as a follower. The second is simultaneous where each agent simultaneously exerts effort. A key result is that the sequential mode dominates when teaching and learning are complements, but the simultaneous mode dominates if teaching and learning are substitutes.     

面向服务供应链的知识共享机制与模型研究

客户需求的个性化和服务产品的同质化矛盾日益凸显,使得服务企业纷纷寻求更科学的服务供应链运作模式去获取竞争优势.服务供应链中的服务资源在供应链上具有多重属性,不同运作主体在服务供应链上处于不同的运作级别,因而对供应链运作流程的理解存在较大的差异性,导致服务供应链在知识管理过程中难以产生面向供应链整体的、紧密结合流程的服务运作知识.针对服务供应链资源管理的复杂性和共享知识的异构性,提出了基于网格管理的服务供应链资源与知识集成框架,旨在实现服务供应链中知识与资源要素的有机结合,并在此框架基础上提出了服务供应链知识共享模型,该模型从服务供应链的资源匹配和知识要素整合两方面提出并揭示服务供应链知识共享的关键流程和环节.
