实际控制人特征与上市公司价值关系研究——基于股权分置改革后的实证分析

本文根据2007年度上市公司披露的实际控制人资料，将上市公司分为国家控制和非国家控制两类，国家控制分为国资委控制和国资委以外的其他政府部门控制，非国家控制包括民营企业控制等。实际控制人特征与公司价值关系的分析表明实际控制人的所有权有正的激励效应，所有权与控制权的分离有负的壁垒效应，较长的控制链有助于减轻政府对国有公司的干预，国资委控制的公司价值优于国资委以外的其他政府部门控制的公司价值。     

Understanding the intention to use mobile shopping applications and its influence on price sensitivity

This study employs an extended technology acceptance model (TAM) and the theory of diffusion of innovations (DOI) to understand the intention to use mobile commerce applications for shopping purposes. The variables—perceived enjoyment, perceived risk and personal innovativeness—were added to the original model. The price sensitivity criterion was predicted using the variables—perceived risk, personal innovativeness, satisfaction and the intention to use. An online questionnaire was circulated nationwide through email to verified e-commerce users and a sample of 675 respondents was taken for analysis through structural equation modeling approach. Gender, experience and frequency of using mobile shopping applications were used as moderators for all relationships. Findings of this study reveal that personal innovativeness and perceived risk play a major role in deciding the intention to use mobile shopping applications. Users who are highly innovative and with a higher intention to use mobile shopping applications are less sensitive to price. Various managerial implications including applications to differential pricing, improving adoption pace and segmenting consumers to design marketing strategies are discussed.     

S-values and Bayesian weighted all-subsets regressions

This paper compares and contrasts Bayesian variable-exclusion methods proposed by Eduardo Ley and coauthors with methods proposed by Raftery and Sala-i-Martin et al. and with the s-values proposed by myself. A distinction is drawn between estimation uncertainty which is the focus of Ley׳s research and model ambiguity which arises in Ley׳s work and is the focus of my own recent proposal. The discussion is organized around the prior covariance matrix, which needs to be diagonal to support all-subsets regressions. The basic question addressed here is: what aspects of the prior covariance matrix can be taken as known, what aspects can be estimated and what aspects require a sensitivity analysis because they are neither known nor estimable. When diagonality is in doubt, we are more-or-less forced into a model ambiguity sensitivity mode because the data are never rich enough credibly to estimate the full prior covariance matrix. When diagonality is assumed, the data evidence, though very limited, can help to estimate the diagonal elements, but this literature has not yet produced a compelling conventional treatment which will necessarily include both estimation uncertainty and model ambiguity as they relate both to the diagonal values and to the rest of the prior covariance matrix. But there has been a lot of progress.     

The Internet and Its Relationship to Buyer Behavior Theory

ABSTRACT

The Internet is the newest, most-rapidly changing and fastest-growing buying medium existing today. Its markets are increasing in number and complexity, more nearly reflecting the population in general. A valuable academic model for Internet marketers to consider when developing a business plan is an early buyer behavior model developed by Phillip Kotler, his Input-Output Model. Internet marketers should investigate outside influences on the potential buyer (Kotler's Inputs), means of reaching the prospect effectively (channels), the buyer's frame of mind (processor), and the choices available (outputs). Current “e-tail” examples are given for each of the four components in Kotler's model. Consulting companies that can assist marketers in attracting buyers have found the following techniques helpful: developing or fine tuning Internet sites, developing site-partnering strategies and online focus groups, as well as providing programs that watch prospects as they peruse a site.

The effect of environmentally friendly perceptions on festival visitors’ decision-making process using an extended model of goal-directed behavior

This study examined the effect of environmentally friendly perceptions on the behavioral intention of visitors at the Boryeong Mud Festival in South Korea. The results of the on-site survey (N = 400) reveal that three environmentally friendly perceptions formed positive and significant causal relationships with the constructs in the extended model of goal-directed behavior (EMGB). Attitude, subjective norm, and positive anticipated emotion affected desire, which, in turn, influenced the behavioral intention. Three elements, volitional, non-volitional, and emotional aspects, were proven to be crucial in comprehending the perceptions and behaviors of the nature-based festival attendees. The findings of this study will shed light on a better understanding of the decision-making processes of festival visitors when environmental issues are incorporated.     

创业社会网络中隐性知识转移激励模型研究

创业社会网络中隐性知识转移能够为创业带来持续发展动力，但一般的显性契约无法消除隐性知识转移过程中传播者可能存在的短期行为。从隐性知识转移的信任机制出发，将声誉模型与委托代理理论相结合，建立了拟合隐性知识传播者心理和行为特征的动态激励模型，分析了声誉效应在提高创业社会网络隐性知识转移效率中的作用，探讨了声誉效应的主要影响因素，并针对如何有效发挥隐性知识转移中声誉效应的激励作用提出了建议。     

Matching mechanisms and matching quality: Evidence from a top university in China

We compare competing college admission matching mechanisms that differ in preference submission timing (pre-exam, post-exam but pre-score, or post-score) and in matching procedure (Boston (BOS) and serial dictatorship (SD) matching). Pre-exam submission asks students to submit college preferences before entrance exam scores are known, whereas post-score (post-exam) submission removes (reduces) score uncertainties. Theoretical analyses show that although mechanisms with post-score submission or SD matching are ex-post fair and efficient, they are not so ex-ante. Instead, the mechanism with pre-exam submission and BOS matching can be more fair and efficient ex-ante. These hypotheses are supported by empirical test on data from a top school at a top-ranked Chinese university with identification based on temporal and provincial changes. We find that although students admitted under the pre-exam BOS mechanism have lower college entrance exam scores than students admitted through other mechanisms on average, they exhibit similar or even better college academic performance.
