竞争情况下零售商的产品组合决策研究

本文研究了市场竞争情况下两个零售商横向差异产品组合决策,基于multinominal logit(MNL)模型刻画消费者选择行为并建立基本模型,得到市场相互独立时的最优产品组合.将市场竞争情况下的产品组合决策细分为四种情形并研究了零售商进入市场顺序的影响,对比了市场相互独立与竞争情况下的结果.结果表明:市场竞争时的产品多样化程度不低于市场相互独立的情况;部分产品存在两个零售商的利润空间是零售商选择重复产品必要条件;市场相互独立时的最优解外的产品有利可图是产品多样化程度高于市场相互独立情况的必要条件;零售商进入市场存在先后顺序时,信息不对称不影响均衡结果.     

竞争环境下ODM厂商自有品牌的市场进入策略分析

在经济全球化背景下,越来越多的原始设备制造商(original equipment manufacturer, OEM)开始考虑创建自有品牌以实现向原始设计制造商(original design manufacturer, ODM)部分角色的转变.显然,ODM是否创建自有品牌进入市场会对相关企业及供应链产生重要影响.本文针对ODM与OEM构成的二级供应链系统,在不同博弈理论框架下分析了ODM自有品牌的市场进入策略及对OEM和供应链系统的影响.研究表明ODM的市场进入能有效缓解供应链的双重边际效应,但该效应会随着OEM渠道成本优势的扩大而减弱.而当OEM的渠道成本足够低时,ODM的市场进入可能对OEM也是有利的,此时ODM与OEM可实现"双赢".最后,将模型拓展至Nash讨价还价和Bertrand价格竞争情形,分析并验证了结论的鲁棒性.     

Two Tales of Return Predictability: The Case of Asia–Pacific Equity Markets

If past prices can successfully predict future price movements, it would contradict the notion of weak‐form market efficiency. Return predictability can be assessed via a variety of random walk statistical tests or via the application of mechanical trading rules. Findings of return predictability and state of market efficiency are compared by applying a battery of popular random walk statistical tests and a large set of mechanical trading rules to a family of equity indexes in Asia–Pacific equity markets over a 20‐year period of time. Inferences drawn from different random walk based econometric tests of market efficiency often disagree among themselves and tend to exaggerate the extent of predictability in returns. Testing of return predictability via a set of mechanical trading rules allows one to account for a possible data snooping bias, error measurements due to nonsynchronous trading and market frictions such as trading costs. Persistent predictability of returns that cannot be explained by the combination of data snooping bias, nonsynchronicity bias and moderate level of transaction costs is found in just two emerging equity markets in the region.

Optimal policy with a total order quantity commitment contract in the presence of a spot market

In this paper,the optimal policy is considered when the buyer faces two supply sources:one is the contract supplier from which the buyer orders over a specific contract period(say,a year) at a pre-agreed price,and the other is the spot market.However,when ordering from the contract supplier,the buyer must fulfill a pre-determined total order quantity,or the so-called definite total order quantity commitment,over the whole contract period.In other words,the commitment secures the buyer a fixed price but obliges him/her a total order quantity over the contract period.Although the spot market gives the buyer more flexibility in terms of order quantities,its prices are volatile.Such a combination of contract and spot procurements is often observed in practice.Within the contract period,there are multiple sub-periods,during each of which the buyer reviews the inventory,issues an individual order,and uses the on-hand inventory to meet the random demand.Thus,in each(ordering) period,the buyer will weigh between the current known spot price(by procuring from the spot market) and a lower future price(by waiting while consuming the remaining commitment).An optimal dual ordering policy is characterized for each period,depending on the on-hand inventory level,the spot price,and the remaining commitment quantity.The optimal policy in each period is also shown to be independent of the contract price.Through a numerical study,the inventory cost is demonstrated to be(1) insensitive to the contract price when the total commitment quantity is lower than the total expected demand over the contract period and(2) non-increasing in the variability of spot prices.
