Behavioral Identification in Coalitional Bargaining: An Experimental Analysis of Demand Bargaining and Alternating Offers

Alternating‐offer and demand bargaining models of legislative bargaining make very different predictions in terms of both ex ante and ex post distribution of payoffs, as well as in the role of the order of play. The experiment shows that actual bargaining behavior is not as sensitive to the different bargaining rules as the theoretical point predictions, whereas the comparative statics are in line with both models. We compare our results to studies that attempt to distinguish between these two approaches using field data, finding strong similarities between the laboratory and field data regardless of the underlying bargaining process.     

基于讨价还价能力的竞争供应链渠道结构绩效研究

本文就独立分销渠道的讨价还价理论在竞争供应链渠道结构面临的问题进行建模,对不同讨价还价能力和产品差异的竞争渠道结构的演化过程进行分析,发现产品与零售商讨价还价能力的差异对竞争渠道结构的选择具有重要影响,并给出了相应结构的演变过程和均衡结果的范围.拓展了Iyery的单渠道结构理论的结果,并为不同环境下渠道结构的选择提供了理论依据.     

基于讨价还价的私募基金机制比较研究

作为私募基金的主要形式，有限合伙制具有比公司制更高的激励作用，原因可能是两者在契约设计上的不同。本文引入讨价还价模型对公司制与有限合伙制进行分析，求解了两种机制下的均衡契约。研究发现，股东(或有限合伙人)和经理(或普通合伙人)之间的博弈等价于包含外部选择的讨价还价博弈，当经理保留收益不断提高，有限合伙制将逐步取代公司制。进一步地，有限合伙制将给出更高的分成比例，进而实现更高的激励，更有效地利用人力资本。     

供应链中CSR运作:相互激励、CSR配置与合作

基于Baron为代表的战略CSR观点和一条由上游制造商和下游零售商构成的两级供应链,用制造商和零售商是否被要求实施CSR行为来描述供应链中的CSR配置,分别建立求解了三种CSR配置下的三阶段非合作运作模型。相应的均衡社会业绩和经济业绩之间的比较结果表明,在消费者对供应链中的CSR行为具有积极反应的条件下,由于制造商和零售商的CSR行为之间的策略性互补性导致的相互激励机制,使得“制造商和零售商各自为自己的CSR行为负责”这一CSR配置获得的经济业绩和社会业绩均较高。进一步,合作运作下的Nash讨价还价解显示,由于合作的运作方式可以克服非合作运作中存在于产品交易阶段的双重加价的问题和CSR策略性行为互动阶段的CSR行为动机不足问题,从而可以进一步提高社会业绩和经济业绩。这些结果一方面为解决"哪个节点企业应当对供应链整体的社会责任行为负责"这一争议提供了一个理论回应;另一方面,指出供应链中的CSR行为的管理,重点不是CSR在供应链中如何配置,而在于是否采用合作的运作方式。     

基于财富效用的产权协商交易定价的计算求解和参数分析

本文以案例研究的方式,根据人们对财富价值的偏好,通过构造产权交易中所获利润的财富效用函数,建产了权交易定价的协商模型,导出协商交易价格的加权边际效用零和方程。通过案例的数值计算研究了交易人的偏好,交易底价,协商势力和信息量等参数的不对称性对均衡价格的影响。进一步分析了产权买方财富拥有量变动对均衡价格的影响。本文研究结论可为产权协商交易定价的机制设计提供理论依据。     

Does Industrial Composition Matter for Wages? A Test of Search and Bargaining Theory

Does switching the composition of jobs between low‐paying and high‐paying industries have important effects on wages in other sectors? In this paper, we build on search and bargaining theory to clarify a key general equilibrium channel through which changes in industrial composition could have substantial effects on wages in all sectors. In this class of models, wage determination takes the form of a social interaction problem and we illustrate how the implied sectoral linkages can be empirically explored using U.S. Census data. We find that sector‐level wages interact as implied by the model and that the predicted general equilibrium effects are present and substantial. We interpret our results as highlighting the relevance of search and bargaining theory for understanding the determination of wages, and we argue that the results provide support for the view that industrial composition is important for understanding wage outcomes.     

Costly Bargaining and Renegotiation

We identify the inefficiencies that arise when negotiation between two parties takes place in the presence of transaction costs. First, for some values of these costs it is efficient to reach an agreement but the unique equilibrium outcome is one in which agreement is never reached. Secondly, even when there are equilibria in which an agreement is reached, we find that the model always has an equilibrium in which agreement is never reached, as well as equilibria in which agreement is delayed for an arbitrary length of time. Finally, the only way in which the parties can reach an agreement in equilibrium is by using inefficient punishments for (some of) the opponent's deviations. We argue that this implies that, when the parties are given the opportunity to renegotiate out of these inefficiencies, the only equilibrium outcome that survives is the one in which agreement is never reached, regardless of the value of the transaction costs.     

存在议价能力和副产品协同生产的制造商最优产量决策

考虑由环保型制造商和处理厂构成的两级供应链结构，其中上游制造商进行主产品的生产，而下游处理厂通过对废料加工进行副产品的生产。基于供应链成员之间存在不同议价能力的情形，构建了上游制造商将产生的废料给下游进行处理的协同生产模式，给出了主产品的均衡产量决策和废料的最优交易价格以及制造商关于废料的最优处理策略。研究结果表明，制造商的废料处理策略取决于消费者对副产品产量的敏感程度。当消费者对副产品产量较敏感（不敏感）时，制造商会选择自己处理废料（给处理厂进行加工）。此外，随着制造商议价能力的上升，制造商的均衡利润上升，而处理厂的均衡利润下降。最后发现本文的基本结论在随机产出环境下依然稳健。     

基于供应链的合作促销与定价问题

本文针对供应链中厂商和销售商之间的合作促销问题,使用博弈论的方法主要就最优的合作促销费用投入和定价进行了研究。首先讨论了传统的厂商为领导者,销售商为跟随者的情形,接着考虑到如今销售商地位的提高,对此进行了拓展,讨论了销售商为领导者的情形。最后以前两种情形为参照,建立了厂商和销售商之间Pareto改进的合作促销模型,并利用Nash讨价还价和效用理论得出了Pareto改进情形下的最优结果。     

Target intermediate products setting in a two-stage system with fairness concern

In a two-stage system with two divisions connected in series, fairly setting the target outputs for the first stage or equivalently the target inputs for the second stage is critical, in order to ensure that the two stages have incentives to collaborate with each other to achieve the best performance of the whole system. Data envelopment analysis (DEA) as a non-parametric approach for efficiency evaluation of multi-input, multi-output systems has drawn a lot of attention. Recently, many two-stage DEA models were developed for studying the internal structures of two-stage systems. However, there was no work studying fair setting of the target intermediate products (or intermediate measures) although unreasonable setting will result in unfairness to the two stages because setting higher (fewer) intermediate measures means that the first (second) stage must make more efforts to achieve the overall production plan. In this paper, a new DEA model taking account of fairness in the setting of the intermediate products is proposed, where the fairness is interpreted based on Nash bargaining game model, in which the two stages negotiate their target efficiencies in the two-stage system based on their individual efficiencies. This approach is illustrated by an empirical application to insurance companies.     

基于谈判机制的优质货架与通道费

大型零售企业能够收取通道费的重要基础在于它所提供的货架资源尤其是优质货架能够在较大程度上提升制造商的市场销量,改善制造商的经营状况,增加制造商的利润。本文以货架对消费者效用的影响机制为研究基础,构建了相应的需求函数,并通过三阶段动态博弈模型分析了货架对零售价格、市场销量、厂商利润的影响,然后从制造商、零售商的参与约束以及渠道成员的利益协调等角度出发,讨论了通道费的可能性、存在性与合理性,最后从消费者福利的角度对零售商收取通道费的行为提出了相应的政策建议。     

组合拍卖与议价谈判机制设计研究

设计了一种先组合拍卖再议价谈判的多物品出售两阶段机制.论文分析表明,机制的组合拍卖阶段保持了VCG机制的激励相容性质,在机制的议价谈判阶段,存在4种不同类别的获胜投标者,就拍卖者将采取的不同价格策略,可将其区分为第1类投标者和第2类投标者.据此,找到了拍卖者采取不同价格策略的相应条件.给出了该机制中拍卖者与任意获胜投标者之间的博弈均衡路径.就买卖双方的总估价而言,存在不同相对关系下的不同交易结果.对比该机制和经典VCG机制,该机制改进社会交易福利值为:第1类投标者在议价价格和VCG价格下带给拍卖者利润的变化值.此结果表明,该机制的社会交易福利优于经典VCG机制.     

Efficiency improvement from multiple perspectives: An application to Japanese banking industry

The current study focuses on efficiency improvement for banking systems from multiple perspectives, which have different definitions of input/output about various attributes of a banking system. In this research we utilize data envelopment analysis (DEA) and Nash bargaining game (NBG) theory to improve inefficient banks in order to: (1) Make the inefficient bank be the state of Pareto Optimality for multiple perspectives, which can avoid discontentment of some perspectives. (2) Improve a bank by changing its attributes and provide various improving schemes for decision makers. A numerical case study of Japanese banks is also given to show the results of equilibrium solution from multiple perspectives.     

实报还是谎报——双边信息激励与供应链效率

探讨了双边不对称信息下供应链信息真实分享和谎报对效率的影响。首先,给出完全信息下的最优商品交易量和供应链利润作为比较基准。其次,构建双方信息真实分享的激励模型。研究发现激励双方信息真实共享所需的信息租金降低交易量和供应链利润。再次,构建允许信息谎报的交易量谈判模型。研究发现,供销双方都偏好高报自己的信息类型。个体谎报信息的幅度随着谈判力增加而减小。拥有绝对谈判力的一方不会谎报信息。供应链效率与谎报信息的幅度、成本上界以及销售价格相关。最后,通过数值算例对实报信息和谎报信息下交易量、供应链个体利润及效率进行对比分析。研究结果为管理实践提供一定的洞见:供应链企业是否激励双边信息分享可根据双方成本大小进行选择。

Co‐opetition and Investment for Supply‐Chain Resilience

This paper considers the problem of disruption risk management in global supply chains. We consider a supply chain with two participants, who face interdependent losses resulting from supply chain disruptions such as terrorist strikes and natural hazards. The Harsanyi–Selten–Nash bargaining framework is used to model the supply chain participants' choice of risk mitigation investments. The bargaining approach allows a framing of both joint financing of mitigation activities before the fact and loss‐sharing net of insurance payouts after the fact. The disagreement outcome in the bargaining game is assumed to be the result of the corresponding non‐cooperative game. We describe an incentive‐compatible contract that leads to First Best investment and equal “gain” for all players, when the solution is “interior” (as it almost certainly is in practice). A supplier that has superior security practices (i.e., is inherently safer) exploits its informational advantage by extracting an “information rent” in the usual spirit of incomplete information games. We also identify a special case of this contract, which is robust to moral hazard. The role of auditing in reinforcing investment incentives is also examined.     

考虑渠道权利结构的产品服务能力竞争机制研究——制造商服务视角

本文针对两个制造商和一个零售商构成的产品服务供应链,以制造商提供服务为视角,研究了产品服务能力竞争问题。运用Stackelberg动态博弈,分别从制造商Stackelberg、零售商Stackelberg和垂直纳什三种不同权利结构情形,求解了供应链成员企业的均衡策略。通过分析服务成本与不同渠道权利结构下均衡结果之间的变化关系,提出能够满足不同客户需求特征的产品服务能力竞争策略。结果表明,当价格与服务能力水平都比较低时,RS价格领先型策略能够满足实惠型客户需求;当服务能力水平比较高时,VN服务领先型策略能够满足经济型客户需求;当价格比较高时,MS产品领先型策略能够满足专业型客户需求;当价格与服务能力水平都比较高时,产品服务融合策略能够满足品质型客户需求。最后,结合批发价格、服务能力水平、零售价格与服务成本之间的数值变化关系,分析了产品服务能力竞争策略的有效性。     

Multilateral Contracting with Externalities

This paper proposes a model for multilateral contracting, where contracts are written and renegotiated over time, and where contracts may impose externalities on other agents. Equilibria always exist and the equilibrium value function is linear and monotonically increasing on the contracts. If the grand coalition, or contracting among all agents, is inefficient, we show that bargaining delays arise in positive‐externality games and equilibrium inefficiency may remain bounded away from zero even as bargaining frictions converge to zero. Otherwise, if the grand coalition is efficient, there are no bargaining delays, convergence to the grand coalition occurs in a finite number of contracting rounds, and the outcome becomes efficient as players become more patient.     

Impacts of demand uncertainty on retailer's dominance and manufacturer-retailer supply chain cooperation

Recent studies in marketing and distribution channels have shown that the balance of power between manufacturers and retailers is shifting. Based on this observation, we investigate a two-echelon supply chain with a manufacturer and a retailer in this paper. We first develop retailer-dominant non-cooperative game models by introducing a sensitivity of retailer's order quantity to manufacturer's wholesale price; then we analyze two cooperative scenarios, in which the Nash bargaining model is utilized to implement profit sharing between the manufacturer and the retailer. Under the assumption that the manufacturer and the retailer are risk-neutral, we find that the manufacturer and the retailer can bargain to cooperate at any level of retail-market demand uncertainty with exogenous retail price. However, the cooperation is conditional on retail-market demand uncertainty with endogenous retail price: it can be implemented if the fluctuation of retail-market demand is relatively small, and the measure of retail-market demand uncertainty does not exceed an upper bound. Theoretical and numerical analyses show that the retailer's dominance over the manufacturer increases with the increase in the sensitivity of retailer's order quantity to manufacturer's wholesale price under a limitation of retail-market demand uncertainty. Numerical analyses also show that the retailer's dominance decreases with the increase in retail-market demand uncertainty.     

基于讨价还价博弈下的供应链回购合同研究

分析了由一个供应商和一个零售商组成的系统.不确定性需求实现之后,系统成员能够对交易合同参数进行讨价还价,从而确定双方之间的收益分配比例.研究得出,首先,相对于分散控制系统,基于讨价还价下的分散控制系统中,成员之间讨价还价会对供应商收益产生负面影响;而对于供应链系统和零售商而言,收益变化趋势取决于双方之间的讨价还价能力的大小.其次,相对于回购控制系统中,在对回购价格进行讨价还价的回购控制系统中,供应商和零售商在期初所签订的回购合同具有抗讨价还价性;而在对批发价格进行讨价还价的回购控制系统中,回购合同是否具有抗讨价还价性,取决于零售商和供应商之间的相对谈判权利.
