An empirical study of dynamic customer relationship management

We apply the Gönül and Shi (1998) approach to the analysis of the optimal messaging and pricing policy mix by studying the past transaction patterns between a local supermarket and its consumers. We develop a dynamic customer relationship management model and investigate the relationship between customer utility and purchasing frequency by modifying the return function of the model discussed in Gönül and Shi (1998). In particular, we extend the analysis to consider a messaging and pricing policy mix, and we use a genetic algorithm in our empirical estimation. When applied to some non-seasonal products in a local supermarket, we find that our model is suitable and far superior to the one-stage model commonly used. Our dynamic model gives the optimal marketing mix strategies in different customer states and the results show that the firm could enjoy a 22% increase in profit.     

外国直接投资与我国技术创新研究

本文运用面板协整工具和动态最小二乘法(DOLS)来检验我国1990-2004年间FDI的技术溢出效应与我国技术创新的相关关系。实证研究的结果显示:FDI与我国技术创新存在着长期稳定的关系;如果跨越了一定的人力资本门槛,那么FDI从总体上对我国的技术创新产生了积极的影响,也可以说人力资本在FDI促进我国技术创新中起着关键的作用。     

Goodwill and dynamic advertising strategies

In this paper, we empirically analyze weekly advertising policies of manufacturing firms in consumer goods markets. We assume firms engage in persuasive advertising, thus policies of firms affect the goodwill of a brand. We introduce a demand and a goodwill production function. A simple transformation of the demand function allows us to identify not only the demand parameters but also the parameters of the goodwill production function. We reconstruct the unobserved goodwill levels using these parameters and past advertising levels. We restrict our attention to Markov Perfect Equilibrium (MPE) strategies which are functions of payoff relevant state variables. Without imposing further restrictions on the dynamic competitive environment, we investigate the relationship between observed advertising strategies—which are assumed to be MPE—and payoff relevant state variables by means of several reduced form specifications. The most important determinant of advertising intensity turns out to be goodwill. We demonstrate that controlling for an advertising campaign significantly improves the explanatory power of the model. JEL Classification L13 . C73 . M30 .

香港工业政策变迁的理论分析——兼论对珠江三角洲地区工业政策转变的启示

目前,世界经济正处于后工业经济向知识经济转型的重要时期。在这一关键时期,如何最大程度地发挥工业在国民经济中的作用,对各国的经济发展与产业转型都具有决定性的影响,而工业经济的发展在很大程度上取决于一国工业政策的方向和内容。本文以20世纪80年代以来香港工业政策的变迁为例,探讨了工业政策在香港经济转型中的静态和动态影响,并通过对香港工业政策变迁经验的探讨,对我国珠江三角洲地区工业政策的未来发展方向和重心提出自己的几点看法。

Dynamic capabilities and firm performance in a financial crisis

In this study, an organization means an active actor that can, at least to some extent, adapt to the environment, mainly within the limits of its resources and capabilities. The article enhances understanding of and explains organizational adaptive behavior in weathering the storm in the business environment resulting from the global financial crisis of 2008. The literature on dynamic capabilities, organizational change, and innovation in the context of organizational performance and survival captures this kind of adaptive behavior. The empirical study builds on a quantitative survey and a qualitative case study covering the food processing, maritime, and media industries. Structural equation modeling, group analysis, and qualitative case comparisons shed light on the connection between the constructs in question. Implications for theory and practice culminate in suggestions for future research.     

The dynamic connectedness and hedging opportunities of implied and realized volatility: Evidence from clean energy ETFs

This paper aims to examine dynamic connectedness and hedging opportunities between the realized volatilities of clean energy ETFs and energy implied volatilities through Time-Varying Parameter Vector Autoregression Model (TVP-VAR) and Asymmetric Dynamic Conditional Correlation (ADCC) GARCH models. TVP-VAR analysis results show that dynamic connectedness increases during turbulence periods. We also determine that clean energy ETFs such as PBW, QCLN, SMOG, and TAN are net volatility transmitters. Surprisingly, OVX is a net volatility receiver, especially with the developments after the Paris Agreement in 2016.As a result of the ADCC GARCH analysis, we determine that the conditional correlation between clean energy ETFs and implied volatility ETFs is asymmetric, and negative information shocks increase the conditional correlation. Although OVX is a cheap alternative for hedging long position risks in clean energy ETFs, VXXLE is more effective than OVX in terms of hedging effectiveness. These findings provide insight for individual and institutional investors, and portfolio managers on how negative and positive shocks change the conditional correlation between assets at different levels.     

虚设还是威慑：退市制度市场效应研究

通过建立动态博弈模型分析股市摘牌的作用机理,实证研究"ST预警—摘牌"退市体系的市场认可程度。结果发现,虽然退市预警制度在短期内能较好地向市场传达风险信号,但在中长期里给予了投资者投机炒作的空间,这有助于解释为何以往理论研究与市场观察结果相悖;即便我国股市摘牌强度相对较低,但市场能识别摘牌强度的信号并对其做出显著反应,摘牌起到了"杀鸡儆猴"的威慑作用。

Does corporate social responsibility influence the corporate performance of the U.S. telecommunications industry?

This study uses a two-stage approach to explore the relationship between the operational performance of U.S. telecommunications companies and their implementation of corporate social responsibility (CSR). In the first stage, this study adopts the dynamic data envelopment analysis model to measure the efficiency of the telecommunications industry in the U.S. from 2004 to 2008. The empirical results show that the corporate efficiency of those companies that implemented CSR was higher than that of those companies that did not. In the second stage, the study adopts OLS and 2SLS to explore the influence of the execution level of CSR on performance. The results show that the Kinder, Lyndenberg, and Domini & Co (KLD) social ratings indexes are significantly and positively related to corporate performance. Finally, this study suggests ways in which corporate policy makers can enhance CSR in order to improve corporate performance in the U.S. telecommunications industry.
