我国城乡居民边际消费倾向的再估算

收入分配是否影响居民消费需求以及产生何种影响,取决于边际消费倾向是否同收入水平相关。文章基于可变参数的状态空间模型,实证估计了我国城乡居民在1978~2012年间的边际消费倾向,估算结果显示:我国城乡居民边际消费倾向在1978~2012年间与收入水平间呈现"倒U"型变动关系;但相比而言,农村居民边际消费倾向要低于同期城镇居民。     

The effect of travel purpose and self-image congruency on preference toward airline livery design and perceived service quality

This paper examines travelers’ preference for airline livery design, which is an important component of sensory experience for tourists. Based on surveys of both U.S. and South Korean respondents, this study finds that airline livery preference depends on travel purpose (i.e. business vs. vacation). Designs preferred by the two travel segments differ in terms of color tone, hue, line, and shape. Business traveler-preferred designs signal punctual, efficient, classy, and safe service; while vacation traveler-preferred designs elicit feelings of fun, friendly, and exotic service. It is also shown that travelers prefer airline livery that is congruent with their situational self-image, depending on the travel occasion at hand. In fact, self-image congruency of design is approximately half of the variance in airline livery preference. Finally, results show that self-image congruency also increases perceived service quality.     

When we are onstage,we smile: The effects of emotional labor on employee work outcomes

A growing body of literature has confirmed the deleterious effects of emotional labor on service employees. The study adds to it by investigating two hypothesized antecedents to emotional labor; affectivity and empathy which is conceptualized as a two-dimensional construct composed of emotional contagion and empathic concern. It also examines the impact of emotional labor on job satisfaction and exhaustion. The results confirmed a two-dimensional structure of emotional labor, emotive dissonance, and emotive effort. Hospitality employees with higher positive affect tend to experience less emotive dissonance while individuals with higher negative affect exert more effort to enact emotional labor. A positive relationship was found between emotional contagion and emotive dissonance, and emotive effort and job satisfaction. The results also suggested a negative relationship between emotive effort and emotional exhaustion. An unexpected negative relationship was found between emotional dissonance and emotional exhaustion. Managerial implications discuss training and acting techniques to more effectively manage employee emotional labor.     

跨国公司制造业R&D投资国别选择的实证研究——以美国跨国公司为例

本文以美国跨国公司为例,对跨国公司制造业海外R&D投资国别选择的影响因子进行了实证研究。结果表明,从世界范围看,跨国公司在东道国的FDI和东道国市场规模是影响跨国公司R&D投资的主要因子;仅就发展中国家而言,东道国市场规模并不影响跨国公司R&D投资;跨国公司的产业类别不同,其R&D投资国别选择的影响因子亦有差异。     

上海燃料油期货上市三周年回顾与我国石油期货市场展望

自2004年8月25日上市至2007年8月1日,上海期货交易所燃料油期货合约累计成交已达6.3亿吨,总成交金额为1.9万亿元.上海燃料油期货价格与新加坡燃料油现货价格、美国WTI原油期货价格的走势保持了较强的相关性,但并不完全跟踪国际市场,而是表现出一定的独立性,更多地反映了中国市场的供需关系,与黄埔燃料油现货价格保持了更强的相关性.上海燃料油期货市场经济功能逐步发挥:形成了反映中国市场的燃料油价格,形成了市场普遍认可的燃料油的"中国标准",推动石油仓储设施建设,提供套期保值规避价格风险的平台,规模化培养石油金融专业人才.在总结燃料油期货成功经验的基础上,上海期货交易所正在研究推出原油、成品油等石油期货品种,已经完成了原油、成品油期货市场运作模式、交易标的选择、合约设计、交易规则等主要的前期工作.     

Monetary policy of a small open economy in the world production chain

In the world production chain there is a small economy that outsources production to its upstream, sells intermediate goods to its downstream and consumes imported final goods. It is shown that in responding to shocks from demand for intermediate goods, from the wage rate in the upstream and from the currency exchange rate between the upstream and downstream countries, the monetary policy of the small country is insignificant in the sense that any attempt of changing its monetary stance to raise national welfare will be offset by the movements of exchange rates.     

Predicting issuer credit ratings using a semiparametric method

This paper proposes a prediction method based on an ordered semiparametric probit model for credit risk forecast. The proposed prediction model is constructed by replacing the linear regression function in the usual ordered probit model with a semiparametric function, thus it allows for more flexible choice of regression function. The unknown parameters in the proposed prediction model are estimated by maximizing a local (weighted) log-likelihood function, and the resulting estimators are analyzed through their asymptotic biases and variances. A real data example for predicting issuer credit ratings is used to illustrate the proposed prediction method. The empirical result confirms that the new model compares favorably with the usual ordered probit model.     

Does intellectual monopoly stimulate or stifle innovation?

This study develops an R&D-based growth model with vertical and horizontal innovation to shed some light on the current debate on whether patent protection stimulates or stifles innovation. We analyze the effects of patent protection in the form of blocking patents. We show that patent protection changes the direction of innovation by having asymmetric effects on vertical innovation (i.e., quality improvement) and horizontal innovation (i.e., variety expansion). Calibrating the model and simulating transition dynamics, we find that strengthening the effect of blocking patents stifles vertical innovation and decreases economic growth but increases social welfare due to an increase in horizontal innovation. In light of this finding, we argue that in order to properly analyze the growth and welfare implications of patents, it is important to consider their often neglected compositional effects on vertical and horizontal innovation.
