中间品技术溢出双门槛效应分析

通常认为,某产业自身进口中间品（Term）和其它产业进口中间品（Tram）对该产业的技术溢出均存在公司规模过大或过小的双门槛效应。基于我国中低技术产业数据,结合公司规模相关理论,采用非线性动态面板回归技术来检验门槛效应。结果表明,Tram对我国中低技术产业的技术溢出不存在公司规模门槛效应,而Term的技术溢出存在公司规模双门槛效应。且当中低技术产业的公司规模小于0.869 097亿元总产值/个时,系数显著为正,暗示我国中低技术产业总体公司规模过于庞大,在吸收外部知识溢出时不具备充分的灵活性。     

养老机构发展呼唤创新——基于北京市海淀区养老机构的调研

由于老龄人口剧增,加之社会转型、政府职能转变和家庭养老功能弱化,老年人群,特别是高龄和带病老年人对于社会服务的需求迅速增长,这无疑给现存的养老服务体系带来巨大的冲击和压力。通过对北京市海淀区养老机构长达数月的调研,我们了解到目前入住老人大多身患多种疾病,身体状况普遍较差,大部分老人选择入住养老机构是出于自己的意愿,但是,老人的收入水平限制了其对机构养老方式的选择。通过调研我们还发现,现存养老机构发展面临着资金不足、经营困难以及许多体制性障碍,为促进养老机构发展,在加大投入力度、加快投入步伐、创新投入方式满足社会对养老机构的需求外,应强化保障性养老机构中政府的作用和理顺养老机构的管理体制。此外,由于短时间内,大幅度增加养老机构确有困难,可以规范管理社会化居家养老服务,起到一定的补充、替代作用。     

Perceived benefits of loyalty programs: Scale development and implications for relational strategies

Positive outcomes of loyalty programs are clear for firms, yet little research examines customer perceptions. To address this gap, this article investigates various perceived benefits of loyalty programs using a multi-benefit framework based on utilitarian, hedonic, and relationship literature. Two quantitative studies, involving 658 French members of loyalty programs, provide a 16-item scale that measures five types of perceived benefits: monetary savings, exploration, entertainment, recognition, and social benefits. The five dimensions have different impacts on satisfaction with the program, loyalty to the program, and perceived relationship investment of the firm. This article offers a discussion of the theoretical and managerial implications of these findings for relationship marketing strategies.     

上海市产学研合作效率评价——基于分行业数据的DEA分析

通过建立产学研合作创新效率的评价指标体系,应用数据包络分析(DEA)方法对上海市13个主要制造业的产学研合作创新效率进行了实证分析。结果表明,上海市政府研发投入的力度较大,产学研合作的体制正在形成,但是尚有一些行业其研发投入的效率还有待提高。因此,在推动产学研合作的过程中要注重竞争机制的引入,同时发挥市场导向与政府引导的作用,不断探索新的产学研合作方式,并结合行业特点动态调整政府介入的方式,因地制宜地制定产学研合作创新的政策,提高产学研合作创新的效率。

American step-up and step-down default swaps under Lévy models

This paper studies the valuation of a class of default swaps with the embedded option to switch to a different premium and notional principal anytime prior to a credit event. These are early exercisable contracts that give the protection buyer or seller the right to step-up, step-down, or cancel the swap position. The pricing problem is formulated under a structural credit risk model based on Lévy processes. This leads to the analytic and numerical studies of several optimal stopping problems subject to early termination due to default. In a general spectrally negative Lévy model, we rigorously derive the optimal exercise strategy. This allows for instant computation of the credit spread under various specifications. Numerical examples are provided to examine the impacts of default risk and contractual features on the credit spread and exercise strategy.     

Local Retail Segmentation Using the CETSCALE

Abstract

The CETSCALE was used to segment a local retail luxury sedan market into pro-import and anti-import groups. Four versions of a newspaper advertisement for both Cadillac and Lexus luxury sedans were tested across these two segments. Non-comparative, weaker indirect comparative, stronger indirect comparative, and direct comparative advertising headlines were used in a between-subjects design. An existing automobile dealership selling both Cadillac and Lexus brands was used as the test sponsor. Results unexpectedly indicate that the pro-import segment favors the hard-hitting direct comparison format significantly less than the anti-import segment, finding it less believable, likable, convincing, and professional, plus more boring.

基于改进的DEA/AHP模型的人工成本投入产出效率评价

通过采用0.1-0.9标度这种更为简便实用的判断尺度,建立了具有完全一致性的互补判断矩阵,妥善解决了AHP判断矩阵的一致性问题,改进了DEA/AHP模型。并基于DEA模型和改进的DEAHP模型分别对盐城市22个行业2009年的人工成本投入产出进行效率评价分析。研究结果显示,基于改进的DEA/AHP模型的评价结果更加具有可区分性,具有更高的解析能力。     

中国养老金隐性债务规模估算

随着我国养老保险体制的转轨,现收现付制下形成的隐性债务开始显性化,形成了庞大的统筹资金缺口.而解决养老金隐性债务的基本前提是要准确测算债务规模.本文在分析隐性债务来源的基础上,将我国参保职工分为五类,采取个体成本法精算出2008年初的养老金隐性债务规模.
