非正式社会化对知识共享影响机制研究

知识是一种独特的有价值的关键资源,对知识的管理和有效利用对于增强组织核心竞争力有着至关重要的作用。但组织内知识流动并非易事,知识共享通常不是自然发生的。组织中员工知识共享水平的提高,需要员工之间进行沟通与交流,社会化为员工沟通交流提供了机会。非正式社会化作为发生在个人层面的社会化类型,对组织中人与人之间的知识共享行为具有非常重要的作用。对来自长江三角洲的13家企业问卷调查数据进行分析,搭建非正式社会化、社会交互作用、权力距离、知识共享4个变量之间的交互作用模型,采用探索性因子分析、验证性因子分析和结构方程分析方法,就非正式社会化对知识共享的影响机制进行了讨论。     

Does it pay firms to register for taxes? The impact of formality on firm profitability

This paper estimates the impact of registering for taxes on firm profits in Bolivia, the country with the highest levels of informality in Latin America. A new survey of micro and small firms enables us to control for a rich set of measures of owner ability and business motivations that can affect both profits and the decision to formalize. We identify the impact of tax registration on business profitability using the distance of a firm from the tax office where registration occurs, conditional on the distance to the city center, as an instrument for registration. Proximity to the tax office provides firms with more information about registration, but is argued to not directly affect profits. We find tax registration leads to significantly higher profits for the firms that the instrument affects. However, we also find some evidence of heterogeneous effects of tax formality on profits. Tax registration appears to increase profits for the mid-sized firms in our sample, but to lower profits for both the marginal smaller and larger firms, in contrast to the standard view that formality increases profits. We show that owners of large firms who have managed to stay informal are of higher entrepreneurial ability than formal firm owners, in contrast to the standard view (correct among smaller firms) that informal firm owners are low ability.     

论民间金融的边界

要解决中小企业融资难问题需要界定民间金融与正规金融的边界。通过将社会网络关系引入民间金融模型,揭示民间金融中行为人的行动逻辑,证明在特定的网络范围内,民间金融能够满足行为人的融资需求。进而,将正规金融引入模型界定民间金融和正规金融的边界,证明在中小规模融资中,民间金融存在成本优势。     

我国民间融资研究最新进展及述评

本文从经济学、法学、哲学伦理三个角度对民间融资的研究文献进行了系统梳理,专家学者从不同角度,基于不同学说和理论,对其存在的效果、影响及地位等方面展开了较为深入的分析和探讨,但仍存在不足之处,需要进一步加强对民间金融的定量分析和比较研究,以适应当今民间金融蓬勃发展之势。     

株洲市辖区农村居民点土地集约节约利用的实证研究

两型村镇建设是"两型社会"建设的重要组成部分,实现农村居民点的土地集约节约利用是"两型"村镇建设的重要内容。在分析株洲市辖区农村居民点土地利用现状以及时空变化的基础上,总结出农村居民点土地利用存在的主要问题,利用灰色关联分析方法,定量测算了制约株洲市辖区农村居民点土地节约利用主要因素的关联度,探讨在"两型社会"建设背景下株洲市辖区农村居民点土地集约节约利用的提升与优化对策,旨在为长株潭城市群两型村镇建设中农村居民点土地集约节约利用提供参考。     

Contract enforcement and the size of the informal economy

This paper describes a model where the size of the informal sector decreases as the degree to which financing contracts can be enforced in the formal sector rises. Agents who choose to operate in the informal sector can evade taxes, but they have no access to official means of contract enforcement. Numerical simulations of the model suggest that lax tax enforcement alone does not suffice to generate a large informal sector. Contractual imperfections, on the other hand, can generate a large informal sector and account for several distinguishing features of the organization of production in developing economies.

我国城镇正规就业与非正规就业工资差异的实证研究——基于分位数回归与分解的发现

本文利用2009年CHNS数据对我国城镇正规就业与非正规就业的工资差异进行实证研究,分位数回归与分解的结果表明:正规就业与非正规就业的教育回报率的差异,随工资分布由低端到高端呈现先升后降趋势,经验—工资线在正规就业与非正规就业明显不同,前者为单调递增的线性关系,后者为倒"U"形曲线关系;正规就业与非正规就业的工资差异主要是由中低端的工资差异引起的;在工资分布中低端和歧视等非市场因素是工资差异的主要原因,而在工资分布高端,工资差异主要来自于教育和经验等个人禀赋差异。     

Informal Sector and Manufacturing Location: In Search of the Missing Links

Abstract

Although the informal sector is very large and unevenly distributed within developing countries, its relative size and location have not been investigated from the perspective of location models. This paper builds a modified Core–Periphery model where formal and informal firms compete in consumer markets. The model suggests that in a peripheral region, where informal goods constitute a competitive alternative to formal goods, a larger critical mass of workers is needed for the formal sector to become profitable. Informal sector competitiveness, however, also increases formal firms' sensitivity to home market effects. Thus, indirectly, a competitive informal sector can foster formal manufacturing agglomeration.

RÉSUMÉ Bien que le secteur informel soit très étendu et distribué de façon irrégulière dans les pays en voie de développement, son envergure et sa distribution relatives n'ont fait l'objet d'aucune étude sur le plan de modèles de localisation. La présente communication crée un modèle « centre–périphérie » modifié, dans lequel des entreprises officielles et non officielles rivalisent sur des marchés de consommation. D'après ce modèle, dans une zone périphérique où les produits informels constituent une alternative à des produits officiels, une masse critique de travailleurs plus importante est nécessaire afin que le secteur officiel devienne rentable. Toutefois, la compétitivité du secteur informel accro??t également la sensibilité des entreprises officielles à des effets sur le marché interne. En conséquence, un secteur informel compétitif peut, indirectement, encourager une agglomération de fabrication officielle.

EXTRACTO Aunque el sector informal es muy amplio y está irregularmente distribuido dentro de los países en desarrollo, su tamaño relativo y localización no se han investigado desde la perspectiva de modelos de localización. Este estudio construye un modelo modificado de centro–periferia donde empresas formales e informales compiten en mercados de consumo. El modelo sugiere que, en una región periférica donde las mercancías informales constituyen una alternativa competitiva a las mercancías formales, el sector formal necesita una mayor masa crítica de trabajadores para ser rentable. No obstante, la competitividad del sector informal también aumenta la sensibilidad de las empresas formales a los efectos del mercado doméstico. Por lo tanto, indirectamente, un sector informal competitivo puede fomentar la aglomeración de la industria manufacturera formal.

     

The dynamics of parallel economies. Measuring the informal sector in Mexico

The existence of parallel economies that operate in the shadows of informality within most Latin American countries is widely recognized by the economic literature. However, its composition, size and effects on economic growth are still open questions. In this paper, we estimate the size and the evolution of the Mexican informal economy in the last three decades using a vector error correction model. In addition to the standard explanatory variables traditionally used in the currency demand approach, we include remittances given their relevance in the Mexican economic system. The results indicate that informality prior to the late 1980s accounted for at least two thirds of GDP, while stabilizing around one third of GDP in the last decade. Furthermore, our estimates provide evidence of a positive long-run relationship between informality and economic growth.     

Tax structures in developing countries: Many puzzles and a possible explanation

Tax policies seen in developing countries are puzzling on many dimensions, given the sharp contrast between these policies and both those seen in developed countries and those forecast in the optimal tax literature. In this paper, we explore how forecasted policies change if firms can successfully evade taxes by conducting all business in cash, thereby avoiding any use of the financial sector. The forecasted policies are now much closer to those observed.
