Option to acquire or divest a joint venture

This paper develops a model for assessing options in joint ventures. The model is used specifically to examine the option to acquire or divest a joint venture, both in the case where the acquisition/divestiture price is specified ex ante in the initial contract and in the case where the price is to be negotiated ex post. The results derived from the model show how the value of the option and each partner's pay‐off from the venture vary with the structure of the option and how the presence of the option may affect the structuring of the joint venture. The main theoretical insights are stated in 12 potentially testable propositions, and possible ways to operationalize some of the propositions for empirical testing are also explored.

The Doctrine of the Mean: Workplace Relationships and Turnover Intention

The present study examines the curvilinear relationships between LMX/TMX and team members' turnover intention simultaneously. That is, members with high LMX, TMX, or both are more likely to have turnover intention. Hypotheses were tested with a sample of 452 nurses, and we adopted the response surface methodology and polynomial regression to test our theoretical model. The hierarchical regression analysis showed that TMX has a U‐shaped relationship with turnover intention but not with LMX. In addition, the results indicate that both the congruence and incongruence of LMX and TMX result in higher turnover intention, but moderate levels of LMX and TMX have the lowest turnover intention. Strengths, limitations, practical implications, and directions for future research are discussed. Copyright © 2018 ASAC. Published by John Wiley & Sons, Ltd.     

The Effects of Victim Anonymity on Unethical Behavior

We theorize that victim anonymity is an important factor in ethical decision making, such that actors engage in more self-interested and unethical behaviors toward anonymous victims than they do toward identifiable victims. Three experiments provided empirical support for this argument. In Study 1, participants withheld more life-saving products from anonymous than from identifiable victims. In Study 2, participants allocated a sum of payment more unfairly when interacting with an anonymous than with an identifiable partner. Finally, in Study 3, participants cheated more from an anonymous than from an identifiable person. Anticipated guilt fully mediated these effects in all three studies. Taken together, our research suggests that anonymous victims may be more likely to incur unethical treatment, which could explain many unethical business behaviors.     

试论农业科技发展的规律性

本文从逻辑和历史相结合的角度,论述了农业科技发展作为一个过程所具有的三个方面的规律性,即：①生活资料需求、生产资料需求、生态环境需求和社会文化需求等多样化的社会需求是推动农业科技发展的主要动力;②清除或缓解生产要素配置中的“瓶颈”制约,是农业科技发展的突破口;③提高由社会生产力和自然生产力构成的农业生产力的整体水平,是它业科技发展的落脚点。     

东南亚深海油气勘探开发形势及对外合作前景

东南亚地区是世界重要的具有深海油气潜力的地区之一,约有100多个深海沉积盆地。2003-2008年,在东南亚发现的新增探明油气可采储量近96亿桶油当量（包括陆地和浅海）。目前在大于200米水深的海域中,近5年新增探明储量最多的国家为马来西亚（17．8亿桶）和印度尼西亚（5．54亿桶）,占东南亚地区这一时期总的新增探明可采储量的24．3％。目前东南亚的深海油气活动规模较小,但深海油气资源潜力不容忽视。该地区深海勘探开发因受边界利益争端等政治问题的影响,存在一定的不确定性和复杂性,这是其对外合作的一个制约因素。我国与东南亚国家的深水合作勘探和开发还处于起步阶段,我们应充分利用地缘优势,适时进入,为我国能源供应多元化提供保障。

A Brief Survey of Modern Optimization for Statisticians

Modern computational statistics is turning more and more to high‐dimensional optimization to handle the deluge of big data. Once a model is formulated, its parameters can be estimated by optimization. Because model parsimony is important, models routinely include non‐differentiable penalty terms such as the lasso. This sober reality complicates minimization and maximization. Our broad survey stresses a few important principles in algorithm design. Rather than view these principles in isolation, it is more productive to mix and match them. A few well‐chosen examples illustrate this point. Algorithm derivation is also emphasized, and theory is downplayed, particularly the abstractions of the convex calculus. Thus, our survey should be useful and accessible to a broad audience.     

Bias Reduction in Dynamic Panel Data Models by Common Recursive Mean Adjustment*

The within‐group estimator (same as the least squares dummy variable estimator) of the dominant root in dynamic panel regression is known to be biased downwards. This article studies recursive mean adjustment (RMA) as a strategy to reduce this bias for AR(p) processes that may exhibit cross‐sectional dependence. Asymptotic properties for N,T→∞ jointly are developed. When ( log ²T)(N/T)→ζ, where ζ is a non‐zero constant, the estimator exhibits nearly negligible inconsistency. Simulation experiments demonstrate that the RMA estimator performs well in terms of reducing bias, variance and mean square error both when error terms are cross‐sectionally independent and when they are not. RMA dominates comparable estimators when T is small and/or when the underlying process is persistent.     

国际资本引入对商业银行效率影响的实证研究

引入国际战略投资者是国内商业银行提高自身竞争力的有效途径之一。本文首先对引入国际资本后可能产生的各项效应进行分析,继而运用数据包络分析(DEA)方法对引入国际战略投资者前后各商业银行的效率进行了测度,说明其变化情况;并以可能造成效率变化的因素为自变量,银行效率为因变量建立线形回归模型,发现资本充足率高低对银行效率并无直接影响,但产权结构与银行效率显著相关。最后给出相关政策建议。
