康芒斯的法经济学思想及其贡献

作为现代西方法经济学的伟大先驱,康芒斯非常重视法律制度在经济发展中的作用。他批评传统经济学把法律制度排除在研究之外的做法。在其著作中,康芒斯通过“交易”这一基本单位把法律、经济学和伦理学联结在一起。康芒斯的法经济学思想主要体现在他的集体行动理论、利益和谐理论和“法制决定论”之中。他对“财产”与“财产权利”的区分及对“交易”概念的一般化都深深影响到法经济学的奠基者——罗纳德·哈里·科斯。而康芒斯将法律制度看成是协调冲突的规则体系的观点,也对现代法经济学中的制度学派产生了深刻的影响。     

Farmer organizations and maize productivity in rural Burkina Faso: The effects of the diversion strategy on cotton input loans

This study analyzes the impact of the diversion strategy of cotton inputs on maize productivity among farmer organization (FO) members in Burkina Faso, based on an endogenous treatment effect model. This impact is assessed by measuring the effects of the producers’ strategy of using part of their cotton inputs for growing other crops, such as maize. The data from a 2014 multisectoral survey in Burkina Faso were used. The main result is that maize productivity is 59.11% lower for FO members who divert their cotton inputs. We suggest the development of financing systems for cereals, similar to those in the cotton sector, and the establishment of monitoring the use of input credits.     

Market maker competition and price efficiency: Evidence from China

We test the relationship between market maker competition and stock price efficiency. Using the number of market makers as a proxy for competition, the results show a strong positive correlation between competition and stock price efficiency. Moreover, price efficiency is higher when competing market makers have higher research ability. We suggest that market maker competition increases price efficiency through two channels: 1) Competition decreases transaction costs, and 2) Uninformed market makers learn from orders submitted by informed market makers through competition. The latter happens only in the group of market makers with higher experiences. The results imply that the price efficiency can be improved by enhancing the competition of market makers with high research ability and experiences.     

Information Processing Hierarchies

This paper characterizes optimal stationary hierarchies based on an information processing model introduced by Radner. We show how the delay, size (number of processors), capacity (the size of each cohort processed), and throughput (frequency of cohort arrival) are related and determine a feasibility frontier in the space of these variables. The structure of efficient hierarchies implementing the points on the feasibility frontier is also specified. These structures are always nonregular; i.e., every agent has subordinates from several different levels. The nature of the long accepted maxim of decreasing returns to scale in management hierarchies is demonstrated. When the production function of the hierarchy is taken to be the number of information items it can process, we find that returns to size and delay are always decreasing in efficient hierarchies, but these variables are complementary in the design problem. Finally, we discuss how the underlying abilities of the processors affect the marginal returns to size and delay. Journal of Economic Literature Classification Numbers: L22, D83.     

小微企业资金约束供应链中的协调融资——基于核心企业的功能价值视角

小微企业资金流瓶颈带来的供应链短板效应不仅成为制约其自身创新发展的桎梏,而且威胁到所在供应链的稳定性和竞争力。根据供应链中核心企业在协助小微企业解决资金约束问题过程中发挥的协调功能,提出了供应链融资协调模式,并对协调模式解决小微企业融资问题的作用机理进行了分析。针对协调模式运作中可能存在的权力配置和运作效率问题,进一步从共同财产权、信息共享和利润分配等方面探讨了使协调模式良性运作的机制设计。     

Social Preferences,Sorting, and Competition*

In this paper, I investigate how an increase in competition for workers influences the impact of social preferences on labor‐market outcomes. By sorting themselves into firms with homogeneous work forces, workers can ensure that they suffer less from social comparisons. Competition promotes choice and thus facilitates sorting. However, competition also boosts rent differences in the labor market, because firms cannot curb internal inequity among its employees without losing workers to competitors. To reduce their exposure to social comparisons, workers might engage in inefficient sorting into unemployment. Consequently, social preferences can have strong effects (i.e., unemployment) in a competitive labor market, whereas they only have a slight impact on labor‐market outcomes in a monopsony.     

Masterful Meisters? Voluntary Certification and Quality in the German Crafts Sector

Voluntary certification systems potentially reduce search costs in markets with imperfect information. Service markets with many heterogeneous firms – such as the crafts market – are prone to information imperfections and can therefore potentially benefit from such informational mechanisms. We examine if the Meister qualification in the German crafts sector improves service quality as perceived by consumers. We find a significant and positive relationship between the Meister title and consumer ratings and conclude that the certificate is a credible sign of quality.     

交易成本对易货经济的影响——瓦尔拉斯均衡“不成立”的一种情形

本文首先用一种新的解析几何方法在易货经济 (即两种商品的纯交换经济 )条件下的一般均衡框架下揭示了价格与消费者的马歇尔需求之间的函数关系。在此基础上 ,由个人承担的交易成本被直接置入。然后 ,本文证明 :如果交易成本的固定项不为零 ,供、求函数将不连续 ;如果同时有非无穷小比例的人口进行同步化决策 ,那么瓦尔拉斯均衡将会被破坏     

基于资产专用性的企业融资决策研究

本文采用Williamson的思路,建立了资产专用性与交易成本、生产成本因素在内的综合交易成本分析模型。分析发现,相对于债务融资而言,股权融资有利于避免按市场规则强行清算带来的专用性资产价值损失,运用包络定理证明专用性程度高的资产具有削减生产成本的作用,专用性程度高的资产以股权融资为佳。     

心理所有权的非均衡发展及其影响效应研究

本文在组织心理所有权的基础上提出工作心理所有权,研究两者分别对组织行为的影响,以及两者之间的非均衡发展对组织行为的影响。经过理论分析和实证检验,本文认为,组织心理所有权和工作心理所有权都可以解释组织承诺、工作满意度、OCB和角色外行为等,但工作心理所有权的解释能力更强。心理所有权在组织和工作层面存在显著差异,呈现非均衡发展的现象。当心理所有权的这种非均衡发展超过一定限度之后,较强的工作心理所有权和较低的组织心理所有权降低了组织承诺和工作满意度,并对OCB和角色外行为产生不利影响。本文在这些研究的基础上,进一步解释了心理所有权"阴暗面"的产生机制,分析了可能产生的员工消极行为并提出了相应的对策建议。
