Marketing Metrics Use in a Transition Economy: The Case of Vietnam

ABSTRACT

This article explores the use of marketing metrics by a sample of Vietnamese firms, providing an example of the use of marketing metrics in a “transition” economy as it grows and becomes more market and marketing driven. The analysis reports usage frequency and then develops a set of “correlation chains” linking firm characteristics, metric use, and various indicators of performance. Vietnamese managers generally report that several types of metrics are used. Ownership structure and industry also impact which metrics are utilized. An initial assessment of chains relating metric use to firm performance indicates that the impact is complex and indirect.     

EXPLICIT SOLUTIONS OF CONSUMPTION-INVESTMENT PROBLEMS IN FINANCIAL MARKETS WITH REGIME SWITCHING

We consider a consumption and investment problem where the market presents different regimes. An investor taking decisions continuously in time selects a consumption–investment policy to maximize his expected total discounted utility of consumption. The market coefficients and the investor's utility of consumption are dependent on the regime of the financial market, which is modeled by an observable finite-state continuous-time Markov chain. We obtain explicit optimal consumption and investment policies for specific HARA utility functions. We show that the optimal policy depends on the regime. We also make an economic analysis of the solutions, and show that for every investor the optimal proportion to allocate in the risky asset is greater in a "bull market" than in a "bear market." This behavior is not affected by the investor's risk preferences. On the other hand, the optimal consumption to wealth ratio depends not only on the regime, but also on the investor's risk tolerance: high risk-averse investors will consume relatively more in a "bull market" than in a "bear market," and the opposite is true for low risk-averse investors.     

城镇居民收入水平对零售业与批发业影响的实证研究——基于协整和向量自回归模型

文章选取1995年-2008年我国城镇居民家庭人均可支配收入和零售业销售总额、批发业销售总额的时间序列数据,通过基于VAR模型的协整分析、脉冲响应分析和方差分解的有机结合进行研究,发现上述序列间存在长期均衡。对标准化协整方程和误差校正模型的分析表明,我国城镇居民收入水平和零售业销售总额、批发业销售总额之间形成了长期的、稳定的关系,且城镇居民收入水平是零售业销售总额、批发业销售总额的格兰杰原因。脉冲响应分析和方差分解均显示,城镇居民收入水平在过去十四年内对零售业、批发业产生了持续性的影响。     

本土企业应对跨国公司"全球化链条"的战略选择

跨国公司在全球经济生活中正发挥着越来越重要的作用,而"全球化链条"是确保其竞争优势的一大利器,它在同中国本土企业的竞争中将日益发挥其威力。中国本土企业采取何种战略应对竞争是理论家们讨论最多的话题,本文先对"全球化链条"的优势进行剖析,然后相应提出中国本土企业应对     

Stationary measures for some Markov chain models in ecology and economics

Summary. Let continuous, exists in for x in . Let be an i.i.d. sequence from F and X₀ be a nonnegative random variable independent of . Let be the Markov chain generated by the iteration of random maps by . Such Markov chains arise in population ecology and growth models in economics. This paper studies the existence of nondegenerate stationary measures for {X_n}. A set of necessary conditions and two sets of sufficient conditions are provided. There are some convergence results also. The present paper is a generalization of the work on random logistics maps by Athreya and Dai (2000).Received: 20 March 2002, Revised: 4 December 2002, JEL Classification Numbers: C22, D9.The author wishes to thank Professor Mukul Majumdar and the referees for several useful suggestions.     

公共商品收费之我见—对“费改税”的再认识

“费改税”并不是简单地变费为税,而是“税费归位”改革工作在当前的表现形式和具体要求,事实上,公共商品的收费如果运用得当,可以成为地方财政一项良好的筹资模式,更是发展中国家缓解财政困境的有效措施,该分析了公共商品收费的理论依据和经济效应,提出公共商品收费应遵循的原则,并借鉴国际经验提出当前“税费归位”工作的重点。     

基于模块化的企业价值网络及其竞争优势研究

以价值模块化为基础,传统的集合型价值链经过解构、整合和重建形成具有差异化竞争优势的模块化价值链。不同企业的价值模块和模块化价值链在共同的界面标准内交叉连接、融合贯通,形成企业价值网络。企业价值网络集聚各成员企业的优势资源,将各种能力要素协同在一个无形的网络平台上,通过不同组织模块之间的协作、创新和竞争,能够产生新的竞争优势。企业以价值模块化为基础,对自身价值链进行整合,融入企业价值网络,能够分享网络内成员企业的优势资源和技术创新成果,共享模块化经济,增强企业核心竞争力和抗风险能力。模块化时代,企业之间的竞争已经演进为企业价值网络之间的竞争。     

试析知识产品的价值形成和实现机制

传统的价值理论认为,商品的价值量取决于社会必要劳动时间,商品按照价值量相等的原则进行交换。商品的价格随商品的供求关系围绕着价值上下波动。知识产品的价值规则与此不同,它是由个别优等劳动时间决定,其价值实现是一种低价递减机制。
