基于固定比例生产技术和多产品随机需求的情形,研究了联产品制造商的两阶段产量和价格联合优化模型。通过反向倒推的优化求解,得到了联产品制造商的最优产量和价格决策以及变化规律。同时研究了需求服从均匀分布时,需求波动对均衡的影响。研究结果表明,在订货成本较低和一种产品的需求波动性较大时,当另外一种产品的波动增大,则该产品的最优订货量增大,同时价格下降。借助数值仿真,分析了价格敏感度和产出比例对最优决策和利润的影响。结果表明,在给定一种产品的价格敏感度时,另外一种的价格敏感度越大,那么该产品的价格就越低,制造商的订货量就下降。当一种产品的产出比例固定时,另一种产品的产出比例上升时,则该产品的价格下降,制造商的订货量下降,总利润上升。 相似文献

在经济下行压力加大、资本市场进一步开放的新形势下,厘清审计市场交易——监管机制,完善审计服务市场尤为必要。借由2010 年审计定价管制政策失效的自然实验,本文通过嵌入双边随机边界模型,得到审计双方的定价交易剩余指标,运用双重差分模型解析价格管制与交易定价的作用机制。研究发现,定价管制失效的原因不在于规制俘获,而在于价格管制与当前的市场效率不匹配。下限管制尽管能够提高审计师剩余,但同时会放大交易定价风险,增加剩余的错配,扰乱交易秩序。上限管制则进一步固化市场的低价竞争。进一步研究发现审计师剩余与盈余质量显著相关,2014年的放开定价管制政策提高了审计师剩余。研究厘清了审计市场交易机制,有利于未来研究审计交易机制的微观影响及与盈余质量的关联,为在新时代把握审计市场交易——监管规律、培育自发良性交易的审计市场提供有益借鉴。 相似文献

金融期货是一种具有独特功能的非常重要的衍生金融工具 ,对规避金融风险有重要意义 ,其作为一种金融资产表现为一种特定的权利。B -S期权模型开创性地表达了这种期权定价理论 ,二项式模型则将各种金融期权定价模型推向简化和实用化。 相似文献

本文考虑由线下零售商实体销售与制造商网络销售构成的网络直销,以及由线下零售商实体销售与线上零售商网络销售构成的网络分销两种制造商双渠道模式,研究“搭便车”行为下制造商模式选择和供应链最优定价与服务决策。研究发现:制造商的渠道选择策略与“搭便车”行为程度、消费者偏好网络渠道程度、价格敏感系数等有关。尤其当消费者受到的服务且对价格的敏感性相同时,制造商会选择网络直销双渠道模式。进一步分析消费者“搭便车”行为和网络渠道偏好对制造商渠道选择和定价决策影响发现,制造商在消费者偏好网络渠道程度比较低时应选择网络分销双渠道模式,而当消费者网络渠道偏好和“搭便车”行为程度都比较高时,制造商应选择网络直销双渠道模式。消费者网络渠道偏好或“搭便车”行为程度越大,两种模式下批发价格应设置的更低。网络直销渠道模式下“搭便车”行为程度越大,网络渠道销售价格应设置的更低,而消费者网络渠道偏好程度越大,网络渠道销售价格应设置得更高。 相似文献

The authors examine the literature with respect to the pricing of initial public offerings and focus upon the relationship
of pricing to the structure and conduct of the investment banking industry. Using a data base of all share offerings undertaken
in the United States over a two and a half year period, the authors find that there is considerable evidence for the proposition
that large, prestigious, and well capitalised investment banks tend to price their share offerings at a higher absolute level
than those not meeting such characteristics. Using classical statistical methods, the authors find that the pricing strategy
of investment banks is connected to their affiliation with investment funds and unit trusts. The motives for such pricing
strategies, the authors argue, lie with the affiliation of investment banks with investment funds, suggesting that the pricing
of new share offerings may be a means of excluding retail investors from participating in the strong returns such issues exhibit. The authors raise legal and regulatory implications
of their findings in the context of the general consolidation observed within the investment banking industry.

《庄子·天下》在中国古代学术史上的意义久被学者们所认识,但诸如:《庄子.天下》对道术体性的真正期望何在?其在论列旧法世传之史、邹鲁六经及百家之学时,其背后的学术内涵是什么?其对百家之学究竟是肯定还是否定?原因何在?所有这一切最终对中国古代学术文化有何等影响?这些问题至今似仍罕为学者所尽数参透,因而有必要再予诠衡论析,考订评量。但其中最为重要的是,中国古代政教制度实践对社会文化的辐射、影响之大,必须予以充分关注。 相似文献

In this paper, we analyze the emerging retail practice of carrying a combined product assortment consisting of both regular “standard” products and more fashionable and short-lived “special” products. The purpose of this practice is to increase store traffic by attracting heterogeneous classes of customers, which drives up sales of standard products due to the potential cross-selling effect. Customers who are primarily attracted by special products will also buy some standard products. In this context, we analyze three decisions that are crucial for a retailer׳s commercial success: the product assortment, the inventory levels and the pricing. We propose an optimization model and an iterative heuristic to analyze the trade-offs between the combined product assortment, the inventory level and the price per product when there is limited shelf space. Using numerical experiments, we show that our heuristic can be trusted and that its accuracy improves when the number of products increases. Our findings indicate that to attract more customers for standard products, a retailer may benefit from carrying low priced special products which, if considered in isolation, would be non-profitable. As the cross-selling effect decreases, a retailer should focus more on the standard assortment by increasing its size and decreasing the prices. However, introducing special products and ignoring the cross-selling effect may decrease a retailer׳s profitability. We show that the introduction of special products involves more than just choosing the right specials for non-loyal customers but impacts the global assortment planning, the standard products and the products pricing. 相似文献

In this short note, we first improve the proof in Zhang et al. [1] to show the strict concavity of the unit time total profit of the whole supply chain with respect to preservation technology investment without approximation. We then generalize the model of Zhang et al. [1] to a broader class of market demand functions. Additionally, theoretical results are provided to illustrate the features of the proposed model. 相似文献

Many firms that sell digital copies of copyrighted materials online face a common dilemma: the use of digital rights management (DRM) to impede pirates can impose restrictions on legitimate use. We introduce a two‐period model in which the use of DRM in the first period affects the probability that a consumer finds a pirated copy in the second period; the threat of legal action reduces consumers’ consumption of pirated copies; and firms choose whether to sell, and at what prices, either strongly or weakly DRM‐protected products, or both. Furthermore, we incorporate the role of uncertainty concerning future levels of piracy. Using a two‐period model with uncertainty, we investigate a firm's optimal DRM strategies and present the optimal pricing strategy as well as product launch strategy under different market conditions. We find that one important characteristic of the optimal strategy is that it is optimal to maintain the same product line configuration strategy for both periods. We also characterize the conditions under which each strategy is optimal. 相似文献

中签率对IPO股票上市价格的揭示作用 总被引:1,自引:0,他引:1
在IPO(in ital pub lic offering)过程中,承销商比投资者更了解公司状况,而投资者本身也具有信息占据的异质性。基于此借鉴信号理论进行模型和实证分析,认为中签率的确可以作为一个信号将有关IPO股票内在质量的信息传递到市场上。具体说就是,中签率越高的IPO公司,将被市场识别为低内在价值公司,表现为较低的初始报酬率。 相似文献
