Aggregation and Optimization with State‐Dependent Pricing: A Comment

A key argument in Caplin and Leahy (1997) states that the correlation between monetary shocks and output is falling in the variance of the money supply. We demonstrate that this conclusion depends on solving for the correlation in the nonstationary state of the model. In the stationary state, that correlation is initially rising.     

The Effect of Competition on Recovery Strategies

Manufacturers often face a choice of whether to recover the value in their end‐of‐life products through remanufacturing. In many cases, firms choose not to remanufacture, as they are (rightly) concerned that the remanufactured product will cannibalize sales of the higher‐margin new product. However, such a strategy may backfire for manufacturers operating in industries where their end‐of‐life products (cell phones, tires, computers, automotive parts, etc.) are attractive to third‐party remanufacturers, who may seriously cannibalize sales of the original manufacturer. In this paper, we develop models to support a manufacturer's recovery strategy in the face of a competitive threat on the remanufactured product market. We first analyze the competition between new and remanufactured products produced by a monopolist manufacturer and identify conditions under which the firm would choose not to remanufacture its products. We then characterize the potential profit loss due to external remanufacturing competition and analyze two entry‐deterrent strategies: remanufacturing and preemptive collection. We find that a firm may choose to remanufacture or preemptively collect its used products to deter entry, even when the firm would not have chosen to do so under a pure monopoly environment. Finally, we discuss conditions under which each strategy is more beneficial.     

有摩擦多期证券市场中的无套利资产定价

产定价理论是现代金融学的核心内容,资产定价的两个基本方法是现代的无套利方法和传统的均衡方法。本文对存在买卖价差、成比例交易费和固定交易费三种摩擦的多期证券市场,用无套利方法研究资产定价理论。分别对不存在套利和不存在强套利的市场,建立了资产定价的基本定理。     

Customer Behavior Modeling in Revenue Management and Auctions: A Review and New Research Opportunities

Customer behavior modeling has been gaining increasing attention in the operations management community. In this paper we review current models of customer behavior in the revenue management and auction literatures and suggest several future research directions.     

Joint Ordering and Pricing Strategies for Managing Substitutable Products

Starr and Rubinson (1978) develop a model to establish the relationship between product demand and relative prices. The notion of relative prices motivates us to consider a situation in which a retailer would either charge the same retail price for all products if he adopts a ‘fixed’ pricing strategy or charge different prices for different products if he adopts a ‘variable’ pricing strategy. In this paper, we develop a base model with deterministic demand that is intended to examine how a retailer should jointly determine the order quantity and the retail price of two substitutable products under the fixed and variable pricing strategies. Our analysis indicates that the optimal retail price under the variable pricing strategy is equal to the optimal retail price under the fixed pricing strategy plus or minus an adjustment term. This adjustment term depends on product substitutability and price sensitivity. We also present two different extensions of our base model. In the first extension, our analysis indicates that the underlying structure of the optimal retail price and order quantity is preserved when there is a limit on the total order quantity. The second extension deals with the issue of retail competition. Relative to the base case, we show that the underlying structure of the optimal retail price and order quantity is preserved in a duopolistic environment. Moreover, our analysis suggests that both retailers would adopt the variable pricing strategy at the equilibrium.     

制服设计与时尚

现代社会,制服已成为社会服饰的重要组成部分.时尚使服装设计充满活力,作为服装设计的一个分支,制服设计也应重视时尚,与时尚相融合.如今的制服设计在款式上更加突出美感,领型更加时尚化,口袋设计更为考究实用,色彩更趋于流行色,面料日益精良.制服设计要展现时代魅力,更要在重视物质文化设计的同时,注重服饰精神文化特征的显现,创造形神同构的设计境界.

基于GCRM模型的信用经济资本测度和贷款定价研究

GCRM模型与ASRF模型相比,能给出与经济资本测度目标相一致的资本数量,而现有文献对GCRM模型的到期收益率没有给出明确的刻画,本文则通过假设资产的到期收益率与其信用经济资本相关,得出了基于GCRM模型的信用经济资本测度和贷款定价方法,它能够刻画借款者的违约概率、违约损失率,以及商业银行的风险偏好（目标支付概率）和资本融资成本对经济资本和贷款定价的影响,为商业银行相关领域的决策提供了参考。     

创业投资利益分割模型研究:基于创业企业家视角的分析

创业企业对创业企业家的激励是否有效决定着创新的成败。为了研究创业投资中的利益分割问题,从创业过程的特征出发,本文首先分析创业企业家的角色特征,应用间接定价理论和交易效率比较,结合委托-代理模型,构造了基于对创业企业家间接定价的创业企业利益分割的两部动态规划模型,并进一步探讨了债权型和股权型利益分割合约的使用条件和创业企业管理团队的选择问题。研究表明:创业企业家和创业资本家的利益分割合约是基于两部动态规划的优化问题;债权型与股权型合约作为利益分割机制对于创业企业家和资本家的效用取决于各自对未来的预期;只有满足一定条件下,创业企业才倾向于选择能力较高的第三方团队充当企业管理者;在能力同等条件下,创业企业倾向于选择创业企业家充当创业企业的管理者。     

多再制造商回收定价竞争博弈

多个再制造商在同一回收市场中获取废旧产品并进行再制造,他们之间存在回收竞争.每个再制造商回收废旧产品的数量取决于自身付出的回收价格,同时和对手们的回收价格相关.目标是最大化各自的期望利润.本文首先利用优化理论和非合作博弈理论,证明了该博弈作为超模博弈,存在唯一的Nash均衡.然后通过比较发现竞争下的Nash均衡价格高于串谋下的合作均衡价格.最后通过数值仿真探讨了再制造商的数目和再制造成本对博弈的影响.
