基于近视理论和虚拟动态理论的适应性行为研究

协调博弈作为一类特殊的博弈,在过去几年受到广泛关注,研究主要集中在协调失败和适应性行为两方面.针对Huyck等研究个体适应性行为的局限性,将近视理论和虚拟动态理论进行扩展.基于实验调查数据,分别找出适合低均衡组和高均衡组的自适应行为模型,同时研究单个个体的适应性行为.研究发现,对于低均衡组,虚拟动态理论是预测中位数最适合的模型,近视理论是预测个体行动最适合的理论模型;对于高均衡组,虚拟动态理论在预测中位数和个体行动方面命中率都是最低的,且大部分受试者基于近视理论预测行动的命中次数最大.该研究丰富了适应性行为研究的相关理论,同时表明了个人利益和团队利益一致的重要性,慎重对待每一次选择并尽可能多参考有价值的信息,才能实现收益最大化.     

侵权法中的作为义务探究

国外立法例对侵权法中作为义务的规制模式不尽相同,中国台湾地区和大陆地区理论界对作为义务的研究在结合中国司法实践方面略显不足。对于侵权法中作为义务的探究,应当将国外立法例、中国理论界的研究成果与司法实践情况结合起来。中国侵权法中作为义务的设计应当遵循如下思路:无须在一般条款中明确作为义务;合同约定不应成为侵权法中作为义务的来源;不应当规定一般救助义务;作为义务来源应当具有层级性,且该层级性应当以重塑安全保障义务为中心。

合法性悖论:淘宝村民间团体的生存困境

大量淘宝网商在农村集聚,新兴"淘宝村"成为农村转型发展的模式之一,随之带来的是村内代表行业共同利益的民间团体不断涌现,这类新生团体的合法性建构及其面临的困境引人关注。一方面,自下而上发育的民间团体具有公众合法性能达致正常运转,却因无法获得体制合法性而陷入生存困境;另一方面,民间团体在获得体制合法性后却没有如预期般长期享受发展优势,反而动摇了先前的公众合法性,进入体制铁牢笼,同样也陷入生存困境,由此造成"合法性悖论"。公众合法性与体制合法性的冲突造成的"合法性悖论",反映了政府"体制控制"过强而民间团体自身对两类合法性的定位模糊,同时也体现了在市场转型日渐深入的背景下所凸显的"国家"与"社会"的矛盾。淘宝村社会组织的发展与"淘宝村"的未来前景息息相关,如何破解"合法性悖论",在当前背景下发挥民间团体的活力,其路径选择和发展模式也为社会治理提出了新的问题。     

D-1,2,4-丁三醇的绿色合成

D-1,2,4-丁三醇(D-1,2,4-butanetriol,BT)是四碳的手性多羟基醇,同时也是极具价值的有机合成中间体,应用十分广泛,特别是在医药和军事工业领域。目前D-1,2,4-丁三醇的工业化生产仍以化学合成法为主,该方法存在反应条件苛刻、产率低、副产物多,易引发环境污染等弊端。目前,利用合成生物学技术,安全高效的生物合成该化学品成为研究的热点。本文评述了D-1,2,4-丁三醇的化学合成和生物合成,以期为D-1,2,4-丁三醇的绿色合成提供理论基础。     

Precise large deviations for the difference of two sums of END random variables with heavy tails

Assume that there are two types of insurance contracts in an insurance company, and the ith related claims are denoted by {X_ij, j ? 1}, i = 1, 2. In this article, the asymptotic behaviors of precise large deviations for non random difference ∑^n₁(t)_{j = 1}X_1j ? ∑^n₂(t)_{j = 1}X_2j and random difference ∑^N₁(t)_{j = 1}X_1j ? ∑^N₂(t)_{j = 1}X_2j are investigated, and under several assumptions, some corresponding asymptotic formulas are obtained.     

A dynamic product quality evaluation based pricing model for perishable food supply chains

Waste stemmed from inappropriate quality control and excessive inventories is a major challenge for perishable food management in grocery retail chains. Improvement of visibility and traceability in food supply chains facilitated by tracking and tracing technologies has great potential to improve operations efficiency. This research aims to reduce food spoilage waste and maximise food retailer's profit through a pricing approach based on dynamically identified food shelf life. The proposed model is evaluated through different pricing policies to exploit the benefits from utilising accurate product shelf life information captured through innovated tracking and monitoring technologies. Numerical analysis is conducted in an illustrative case study.

THE IMPORTANCE OF LEGAL FORM OF ORGANIZATION ON SMALL CORPORATION EXTERNAL FINANCING

This article quantitatively evaluates the impact of legal form of organization (LFO) choices, C versus S corporation, on small business external financing. A treatment effect model is formulated and estimated to examine the relationship between corporate types and chances of obtaining external financing. The estimation takes into account self‐selection bias associated with LFO choices. This article finds that LFO choices mainly affect small corporations' access to external equity capital, but have no significant impact on loan financing. Specifically, when a small corporation selects the C corporate legal form, the probability of obtaining new external equity is eight times higher compared to when it selects the S corporate legal form. Furthermore, the results suggest that better access to external equity investments, loosening business capital constraints, leads to better growth prospects for small C corporations. These empirical results have important macro‐economic implications on corporate financial and fiscal policies. (JEL G32, G38)
