The crowding-out effect of formal insurance on informal risk sharing: An experimental study

This paper investigates the crowding-out effect of formal insurance on informal risk-sharing arrangements via theory and laboratory experiment. Our model and simulation predict that the crowding out of private transfers is often more than one-for-one and will reduce the total risk coverage. Furthermore, the existence of a moderate degree of altruism exaggerates the crowding-out effect, especially when there is an ex-ante income inequality. These predictions are mostly supported by the laboratory experiment, except that the crowding-out effect is not more than one-for-one, and hence the total risk coverage is not significantly reduced by formal insurance.     

国有上市公司董事会非正式层级与财务绩效关系的研究

在公司董事会中,始终存在着一股隐性力量影响董事会的决策结果,进而影响公司的财务绩效。已有研究大多以董事会正式结构或人口统计学特征为切入点,本研究区别于其他学者的关注点,基于董事会非正式层级视角,引入基尼系数模型对董事会非正式层级清晰度进行量化,并以国有上市公司为样本进行实证研究,研究发现：董事会非正式层级的清晰度越高,越有利于提升公司的财务绩效,但是董事会非正式层级清晰度对公司财务绩效的边际促进作用会减少。     

农村非正规金融的微观机理与政策测度:国外文献评述

通过对国外文献关于农村非正规金融问题的研究进行概览,本文发现,农村非正规金融不仅能够降低农户借贷的外生交易费用,还能够降低制度性的内生交易费用;农村非正规金融自发生成的各种内在机制具有较高的制度效率,农村非正规金融可以与农村正规金融共存;以家庭为结点的社区网络是农村非正规金融私人治理机制的基础;为了缓解农户贷款难的问题,由发展中国家政府推出的各种扶贫项目的作用却很有限,因而政府要想有效干预农村金融市场,就必须考虑并充分利用农村非正规金融的作用。但已有研究并未定量分析农村非正规金融与正规金融之间的复杂关系,鲜有文献计量农村非正规金融的经济增长效应;相关的理论研究比较零散,尚未形成一致的理论框架。这就为进一步的研究指明了可选方向。     

产权界定、市场禁入与农村非正规金融——由我国第一家私人钱庄兴衰引发的思考

通过对改革开放后第一家私人钱庄兴衰的史实进行重新考察和审视,本文经研究发现,尽管权力当局把资金自由交易权界定给了监管部门,但因监管成本和信息成本过高而无法保障该产权,个人会通过参与各类非正规金融活动来攫取一部分置于公共领域的权利。本文还基于交易费用理论解释了我国金融市场禁人政策出现松动的原因,也即维持扭曲型二元金融制度的成本以及严禁农村非正规金融活动的费用都越来越高,而且国内的经济形势也提出了放松监管的要求,在这些因素的作用下监管部门执行原有金融抑制政策的力度终于降低了。     

Persistent poverty and informal credit

This paper explores the consequences of nonlinear wealth dynamics for the formation of bilateral credit arrangements to help manage idiosyncratic risk. Using original data on expected wealth dynamics, social networks and informal loans among southern Ethiopian pastoralist households, we find that the threshold at which expected wealth dynamics bifurcate serves as a focal point at which lending is concentrated. Informal lending responds to recipients' losses but only so long as the recipients are not “too poor”. Our results suggest that when shocks can have long term effects, loans are best understood as providing a safety net rather than a scale-neutral insurance mechanism. Furthermore, the persistently poor are excluded from social networks that are necessary to obtain loans given in response to shocks.     

论我国农村金融组织体系的现状、存在问题及对策

现阶段我国农村金融组织体系存在的问题主要有:正规性的农村金融组织严重不足,农村金融体系结构与运作机制存在缺陷,机构网点少,产品和服务单一,支农功能不强,农村资金外流严重,"三农"贷款难等。针对上述问题,必须并加快农村金融改革,完善农村金融体系,建立以政策性金融组织为基础、商业金融为发展方向的分工协作的农村金融服务组织体系,包括构建分工合理、投资多元、功能完善、服务高效的农村金融市场体系和业务品种比较丰富的农村金融产品体系,增强为"三农"服务功能。     

非正式制度、市场秩序优化与经济稳定增长

非正式制度是制度结构中最为重要的方面,它对社会经济及市场秩序的影响远比正式制度的影响要大和更持久。中国在优化市场秩序和推进经济的稳定持续增长的过程中,加强非正式制度的建设显得十分重要。     

Poverty and informal economy participation

This paper uses a household survey of the Romanian informal economy to analyse the effects of poverty on informal economy participation. We begin by developing a simple theoretical model, which shows that the participation is driven by low income and the gap between desired and actual income level. We then estimate the determinants of households’ participation in the informal economy. Empirical findings are consistent with the theoretical prediction. In addition, a positive association between husbands and wives working in the informal economy implies the deep poverty faced by a family whose head participates in the informal economy.     

我国农村正规金融与非正规金融效率分析

高效率的金融制度对经济发展提供强有力的资金支持,可以提高经济的总体竞争力,促进经济增长。对农村信用社、农业银行、农业发展银行和邮政储蓄银行等正规金融机构和村镇银行、小额贷款公司等非正规金融组织的效率进行调查,从资金配置效率、适应性效率和运行效率方面进行分析,结果显示：正规金融制度的效率偏低,非正规金融组织的效率偏高;两种金融制度的效率有各自的空间,在规模和范围较小时,非正规金融制度效率更高,而超出一定的发展范围和规模,正规金融制度的优越性则进一步凸显。     

Coordination in global R&D organizations: An examination of the role of subsidiary mandate and modular product architectures in dispersed R&D organizations

International research and development (R&D) operations require a significant amount of coordination between the headquarters and the subsidiaries in order to integrate the dispersed activities in one final product. This article explores what mechanisms multinational companies (MNCs) use to coordinate their overseas R&D units. Based on a multiple case study involving nine MNCs with overseas R&D subsidiaries of varying mandates, we find that R&D sites with high technology and/or market orientation tend to be coordinated by informal mechanisms while sites with little technology and/or market orientation tend to be coordinated by formal mechanisms. Furthermore, it appears that this relationship is strongly affected by the product’s architecture: while rather complex R&D activities are conducted at the systems level and at sites with high technology orientation, less complex R&D activities are conducted at the component level at sites with low technology and market orientation. Finally, the findings suggest that modular product architectures have a coordinating effect in global R&D activities which have the power to lower firms’ overall coordination effort. The findings bear important implications for the effective coordination of MNCs’ international R&D subsidiaries.
