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。     

Population Density and Infrastructure Development

A model is proposed with the following features: (1) there is a publicly accessible transport technology, which is more advanced when there is more specialized labor in it; (2) a high population density facilitates the development of the transport technology; (3) an improved transport technology facilitates a finer division of labor, which in turn increases per capita income. These features are compatible with the phenomena of economic development described by Boserup in 1981. It is also shown that, provided the infrastructure sector can charge the users, and individuals are free to choose jobs, the competitive equilibrium will be Pareto-optimal.

The Chinese interbank repo market: An analysis of term premiums

Because of the lack of short‐term government bonds, the interbank repo market in China has been providing the best information about market‐driven short‐term interest rates since its inception. This article examines the behavior of the repo rates of various terms and their term premiums. The work in this article supplements the study by F. Longstaff (2000), which reports supportive evidence for the pure expectations hypothesis over the short range of the term structure with the use of repo data from the United States. It is found that the pure expectations hypothesis is statistically rejected, although the term premiums are economically small. It is shown that the short‐term repo rate, repo rate volatility, repo market liquidity, and repo rate spreads are all important in determining the term premiums. © 2006 Wiley Periodicals, Inc.

Beyond segmentation: The case of China’s repo markets

This paper explores the reasons behind the discrepancy between interest rates in China’s two repurchase agreement (repo) markets, the interbank repo market and the exchange-traded repo market. The repo rates in the exchange market are at times, significantly higher than those in the interbank market, especially in the first three years of the 2000–2005 sample period. While market segmentation clearly hinders arbitrage, the causes of the repo rate discrepancy are related to the alternative investment opportunities available to market participants and to the volatility differences in the repo rates.     

Hybridization: Understanding the microdynamics of a postacquisition integration process

There is no shortage of theoretical or empirical research on mergers and acquisitions (M&A). Knowledge on the subject has grown substantially in recent decades. However, the integration of firms involved in M&A remains a challenging and often unsuccessful process. In addition, there is a scarcity of research on temporal dynamics within integration projects. This article reports on the postacquisition integration of a business school into a university using the concept of organizational hybridization as a theoretical lens. The aim was to identify the microdynamics that occurred during integration. We conducted an inductive case study, interviewing professionals involved in the integration process, analyzing a wide range of documents, and conducting participant observation over 6 years. Field research revealed that different organizational components underwent distinct hybridization processes that were characterized by different degrees of conflict. This study contributes to the understanding of the microdynamics that occur in postmerger or postacquisition integration processes, focusing on the complex adjustments inherent in these developments.     

高校扩招与教育回报率的城乡差异——基于断点回归的设计

文章基于中国家庭收入调查项目数据（2007年与2013年）,在断点回归设计的框架下分析1999年实施的高校扩招政策对城乡居民受教育年限、收入及教育回报率的影响。结果表明：第一,高校扩招政策的实施使农村居民的平均受教育年限提高了0.59年左右,使城镇居民的平均受教育年限提高了0.85年左右。第二,在断点回归的设计下,农村居民的教育回报率大约为11%,城镇居民的教育回报率大约为8%,高于OLS的估计。虽然实证结果显示教育回报并不存在城乡间的马太效应,但并不意味者城乡间教育发展与收入差距缩小。第三,高校扩招政策一方面显著促进了城镇居民低收入群体教育回报的提升,有效抑制了城镇居民中可能出现的收入差异扩大的"马太效应"。另一方面,高校扩招政策使得农村居民高收入群体教育回报高于低收入群体,在一定程度上导致了农村居民收入差异扩大的"马太效应"。     

Following brands on Twitter: an extension of theory of planned behavior

Due to its immediacy and efficiency, Twitter has recently emerged as a form of marketing communication tool that offers unique advantages for two-way communication between marketers and consumers. This study examines brand-following behavior on Twitter using the Ajzen's model of theory of planned behavior (TPB). Results show that attitude toward brand following, subjective norm, perceived behavioral control, and brand attachment are positively associated with intention to follow brands on Twitter. Consumers’ intention to create (i.e., intention to tweet at brands) and disseminate (i.e., intention to retweet the links of brands) brand-related information, as well as purchase intention, are the outcomes of intention to follow brands on Twitter. Overall findings suggest that TPB model can be used to predict Twitter users’ brand-following behavior. More importantly, our finding that brand attachment drives consumer intention to follow brands on Twitter extends the TPB framework. This study provides both theoretical and managerial implications.     

Demarketing as a differentiation strategy

Demarketing discourages consumers from buying. This paper shows that demarketing can be a profitable alternative when differentiation through product improvements is not cost effective. The impact of differentiating demarketing on profit, market share, consumers, and total welfare is investigated.This research began while Hess was visiting MIT's Sloan School of Management and was finished while visiting University of Haifa; he thanks both for their support.
