基于制造商建议零售价的供应链定价策略

为了阐述制造商建议零售价格对供应链定价策略的影响,以其作为消费者的参照价格,引入到供应链系统中。采用博弈论的方法进行研究,结果表明：当制造商建议零售价格较低时,零售商将采用最低参照价格策略,当制造商建议零售价格较高时,零售商将采用最高参照价格策略,当制造商建议零售价格介于两者之间时,零售商将采用价格保持策略。在此基础上,研究了相关参数对上述三种策略的影响,以及三种策略之间的差异。不仅指出最低参照价格策略或者最高参照价格策略都有可能使制造商的收益最大化,还给出了选择的条件。最后,用数值分析比较了不同策略下的供应链系统收益,指出在最高参照价格策略下的系统收益是最优的。相关结论为制造商建议零售价格制定提供了理论依据。     

基于用户规模的双边平台适应性动态定价策略研究

鉴于交叉网络效应导致用户加入双边平台的效用随用户规模动态变化,提出根据用户规模进行适应性动态定价的策略思想,并运用数值计算方法对该定价策略的效果进行深入研究。首先,引入平台动态竞争建模方法,构建了包含用户规模的双边平台适应性动态定价模型;接着,根据数值计算结果对动态定价与静态定价的效果进行比较;最后,考察了平台竞争主要参数的变化对动态定价策略效果的影响。研究表明：（1）动态定价显著优于静态定价,模型主要参数的取值变动不会改变动态定价具有相对优势这个定性结论;（2）提升服务质量或改变基准用户数不会明显增加动态定价的相对优势,但强交叉网络效应或前瞻性用户都会增强动态定价的相对优势。研究结果有助于平台企业管理者更好地制定平台定价策略。

上市公司定向增发中大股东操纵股价行为实证研究

运用事件研究法,以我国2009—2011年已完成定向增发的109家上市公司为研究样本,分别检验定价基准日前后连续20个交易日的累计超额收益率情况。研究结果表明,以大股东为主的定向增发,定价基准日前20个交易日的累计超额收益率为负,后20个交易日的累计超额收益率为正;而以机构投资者为主的定向增发,定价基准日前20个交易日的累计超额收益率为正,后20个交易日的累计超额收益率为负。这表明,在上市公司定向增发中普遍存在大股东操纵股价行为。

Assortment Planning for Vertically Differentiated Products

We consider the problem of a retailer managing a category of vertically differentiated products. The retailer has to pay a fixed cost for each product included in the assortment and a variable cost per product sold. Quality levels, fixed, and variable costs are exogenously determined. Customers differ in their valuation of quality and choose the product (if any) that maximizes their utility. First, we consider a setting in which the selling prices are also fixed. We find that the optimal set of products to offer depends on the distribution of customer valuations and might include dominated products, that is, products which are less attractive than at least one other product, on every possible dimension. We develop an efficient algorithm to identify an optimal assortment. Second, we consider a setting in which the retailer also determines the selling prices. We show that in this case the optimal assortment does not include any dominated product and does not vary with the distribution of customer valuations when there is no fixed cost. We develop several efficient algorithms to identify an optimal assortment and optimally price the products. We also test the applicability of our methods with realistic data for two product categories.     

Value of and Interaction between Production Postponement and Information Sharing Strategies for Supply Chain Firms

We analyze the value of and interaction between production postponement and information sharing, which are two distinct strategies to reduce manufacturers’ uncertainty about demand. In both single‐level and two‐level supply chains, from the manufacturer's perspective, while information sharing is always valuable, production postponement can sometimes be detrimental. Furthermore, the value of production postponement is not merely driven by savings in inventory holding cost as postponement enables the manufacturer to avoid both excess and shortfall in production. We find that production postponement and information sharing strategies may substitute, complement, or conflict with each other, depending on the extent of the increase in the unit production cost when production is postponed. In a two‐level supply chain, from the retailer's perspective, information sharing and production postponement can be beneficial or detrimental. When information sharing is beneficial to the retailer, the retailer always shares her demand information with the manufacturer voluntarily. In addition, this voluntary information sharing is truthful because inflated or deflated demand information hurts the retailer through a higher wholesale price or a stock‐out. However, the retailer never shares her demand information voluntarily if the manufacturer has already adopted production postponement because production postponement and information sharing strategies always conflict with each other. Even when the retailer does not benefit from information sharing, we show that the manufacturer can always design an incentive mechanism to induce the retailer to share the demand information, irrespective of whether the manufacturer has already implemented production postponement or not. The above findings underscore the need for a careful assessment of demand uncertainty‐reduction strategies before the supply chain players embark upon them.     

Newsvendor Pricing Problem in a Two‐Sided Market

We study the pricing problem of a “platform” intermediary to jointly determine the selling price of the platforms (hardware) sold to consumers and the royalty charged to content developers for content (software), when the demands for content and for platforms are interdependent. Our model elucidates the impact of supply chain replenishment costs and demand uncertainty on the strategic issues of platform pricing in a two‐sided market.     

考虑消费者版权意识差异的信息产品定价策略

依据消费者的版权意识差异将消费者细分为伦理消费者和普通消费者,研究了信息产品垄断厂商的最优定价策略及其对艺术创作者的影响。研究表明:垄断厂商的最优定价因消费者结构、市场敏感性等因素而存在较大差异,没有一个固定的定价策略。高价策略可以得到伦理消费者的支持,但当存在盗版威胁时,垄断厂商因普通消费者的价格敏感特性而面临利润损失,单位可变成本越低,利润损失越大。此外,艺术创作者的期望定价要低于垄断厂商的最优定价,提高版权费率并不能保证给艺术创作者带来收益增加,双方存在定价协调问题。     

规避通胀风险的结构性理财产品设计与定价

在资产通胀风险日益增加的背景下,如何设计出更加符合市场的结构性理财产品并给予其合理定价是目前亟待解决的问题。运用金融工程组合分解技术构建一种创新型幂式双障碍敲出期权,该期权可以作为银行结构性理财产品的内嵌期权,从而获得一种创新型幂式双障碍理财产品,运用风险中性定价理论将复平面的围道积分应用于Laplace逆变换给出期权定价模型,以中国银行HJB0903v为例,研究中国规避通胀风险的黄金挂钩双障碍理财产品定价的合理性,并分析黄金价格波动对HJB0903v触及障碍的概率和理论价格的影响。研究结果表明,产品发行价格稍高于其理论价值,隐含溢价率为0.81%;波动率的增加使触及障碍的概率增加,使理论价格先小幅增加后大幅降低,最终趋于某一稳定值。
