激励企业技术创新的两种管制方式

本文旨在探讨激励垄断企业技术创新的两种管制方式——价格上限管制和最优管制机制。首先分别建立了它们的管制模型,得出了激励企业技术创新的具体的管制机制;进一步地,比较了在这两种管制方式下企业创新的内在激励,以及创新费用的增加对消费者剩余的影响;并分析了当激励企业创新问题引入时,两种管制方式相对优势的改变。     

基于网络流的航空公司飞行员人力资源规划模型

飞行员在各机型、各岗位的流动安排是航空公司人力资源规划的重要内容,是满足航空公司生产需求的主要措施之一.本文根据航空公司实际工作中飞行员流动安排的各种方案与规定利用网络图进行描述并以此建立数学规划模型,最后采用网络流理论给出模型算法.     

基于主成分分析的上市公司利润操纵识别模型

从分析上市公司利润操纵的动机、主要手段及其影响的相关会计科目入手,设计26组有一定配比关系的财务指标,选取1995年～2004年中国证监会以利润操纵名义查处的全部上市公司为样本组,选取同行业规模相近且经营规范的公司为对比组,进行横向对比与相关分析;基于主成分分析法构建上市公司利润操纵行为的识别模型,确定利润操纵行为的识别边界,运用该模型对部分上市公司赢利真实性进行检验,为投资者识别上市公司的利润操纵行为提供一套科学可行的方法.

Net Neutrality,Broadband Market Coverage,and Innovation at the Edge*

Net neutrality (NN) is a widely debated policy issue that has the potential to alter the dynamics of accessing online content. The focal point of the debate lies in whether broadband service providers (BSPs) should be allowed to charge content providers for the preferential delivery of their digital content. This decision will affect broadband market coverage for end consumers as well as the issues of long‐term competition and innovation in the market of digital content. Our research aims to analyze and address these issues. We propose a game theoretical model with three players—the BSP, the content providers, and the consumers—where the BSP, in its capacity as a gatekeeper between the content providers and the consumers, is modeled as a two‐sided market platform. We find that while abandoning the principle of NN might sometimes result in increased consumer surplus and broadband market coverage, it can also hinder the ability of startups to compete against established rivals and thus reduce innovation at the edge. The results should be of great interest to policymakers as they debate on this very crucial issue.

本文分析存在产品替代策略的情况下,闭环供应链在有限产能及废旧物品回收数量有限条件下的最优定价策略,分别得出四种不同情形下的最优定价策略与利润情况。同时,分析产能限制及废旧物品回收数量限制两个条件对最优定价决策与利润水平的影响,并通过数值试验进行验证。     

我国代工企业制造战略与人力资源管理系统的匹配对企业绩效的影响

通过配置理论总结了制造战略、HRM系统与企业绩效关系的假设,并以广东214家代工企业为研究对象,对假设进行实证检验.研究表明,采用大规模服务者和质量定制者战略的企业更倾向于内部型HRM系统,采用专业化承包者战略的企业更倾向于混合型HRM系统,采用对竞争漠不关心者战略的企业更倾向于市场型HRM系统.制造战略与HRM系统匹配的企业,其HRM绩效高于不匹配的企业.     

Dynamic selection of dispatching rules for job shop scheduling

Although the academic contribution to job shop scheduling is abundant, its impact on practice has been minimal. The most preferred approach to job shop scheduling in the industry is dispatching rules. A major criticism against dispatching rules is that there is no single universal rule. The effective choice of dispatching rules depends on the scheduling criterion and existing job shop conditions. In this paper, the authors have proposed a scheduling method based on the analytic hierarchy process, that dynamically selects the most appropriate dispatching rule from several candidate rules. The selection is based on the existing job shop conditions. This method is applied to two formal job shop problems, and the results for single dispatching rules are inferior to the method proposed in this paper.     

单次服务过程中新老顾客质量感知波动的差异分析

服务经济时代,越来越多的顾客开始参与到多阶段化的服务活动中,服务质量管理需要区分新老顾客阶段感知服务质量的波动差异.本文旨在探讨单次服务过程中,面对同样变化幅度的传递服务质量,新顾客和老顾客感知服务质量波动的差异情况.在构建一个三阶段服务质量更新模型基础上,本文以酒店服务为模拟情境,设计了一个三阶段服务过程的行为实验进行分析.研究结果显示,新顾客感知服务质量的变化更容易受到传递服务质量变化的影响,老顾客则更多受到先前消费经验的左右;不同阶段感知服务质量共同影响总体服务质量,尤其是最后阶段感知服务质量的影响更为突出.服务企业应针对不同的顾客群体采取相应的服务质量管理策略.     

Constrained Efficiency in the Neoclassical Growth Model With Uninsurable Idiosyncratic Shocks

We investigate the welfare properties of the one‐sector neoclassical growth model with uninsurable idiosyncratic shocks. We focus on the notion of constrained efficiency used in the general equilibrium literature. Our characterization of constrained efficiency uses the first‐order condition of a constrained planner's problem. This condition highlights the margins of relevance for whether capital is too high or too low: the factor composition of income of the (consumption‐)poor. Using three calibrations commonly considered in the literature, we illustrate that there can be either over‐ or underaccumulation of capital in steady state and that the constrained optimum may or may not be consistent with a nondegenerate long‐run distribution of wealth. For the calibration that roughly matches the income and wealth distribution, the constrained inefficiency of the market outcome is rather striking: it has much too low a steady‐state capital stock.
