Lexical Measures of Social Inequality: From Pigou‐Dalton to Hammond

A measure of social inequality is essentially a rational ordering over a space of social distributions. However, different measures, including the most popular ones, may provide very different rankings over the same set of typical distributions. We thus propose an axiomatic approach to inequality measurement mainly based on the Hammond principle, a natural generalization of the Pigou‐Dalton principle, attempting to clarify the true nature of social inequality: the rich get richer and the poor get poorer. Under the standard assumptions of anonymity and scale independence, we show that a social inequality ordering is the leximinimax measure if and only if it satisfies the first Hammond principle, and it is the leximaximin measure if and only if it satisfies the second Hammond principle.     

Managing organizational entry in China: the roles of newcomer–supervisor exchange,incumbent support,and perceived insider status

The socialization literature has long recognized the important role of perceived insider status in facilitating newcomer adjustment, but knowledge on how to cultivate this desirable psychological state is limited. This study examines newcomer–supervisor exchange as an antecedent of perceived insider status of newcomers, which in turn facilitates their social adjustment and task mastery during organizational entry. We also explore incumbent support as a boundary condition for these effects. We conducted a survey study on 320 new employees and 92 supervisors in China. This study revealed that newcomer–supervisor exchange was related positively to newcomers’ perceived insider status, and perceived insider status mediated the positive relationships of newcomer–supervisor exchange with social adjustment and task mastery. In addition, incumbent support moderated the positive relationship between newcomer–supervisor exchange and perceived insider status, as well as the positive mediated relationships of newcomer–supervisor exchange with social adjustment and task mastery through perceived insider status. Specifically, these relationships were weaker when incumbent support was higher. Theoretical and practical implications were discussed.     

我国新型农村社会养老保险制度改革探讨

Acquisition of Additional Equity Capital by Small Firms – Findings from the National Survey of Small Business Finances

While the importance of venture capital to the growth of small firms has been widely discussed during the past decade, little is known about the acquisition of additional equity capital, especially internal equity capital, by the majority of small firms in the U.S. This paper utilizes the information collected in the Federal Reserve Board’s 1993 and 1998 Small Business Finance Surveys to investigate the acquisition of additional equity capital by small firms. While the importance of public issue markets and venture capital investment in promoting the growth of small dynamic firms cannot be denied, the importance of external equity capital seems to be overstated. Only a very small number of small firms acquired additional external equity capital. It is the internal equity capital, not external, equity, that is one of the major financing sources for most small firms. We found that younger, lower quality firms were more likely to acquire additional internal equity capital than other firms. There appeared to be a “pecking order” of borrowing from internal sources to traditional lenders to non-traditional lenders. In addition, internal equity capital and debt acquired from traditional and non-traditional lenders appeared to be complementary financial resources.

基于空间面板STIRPAT模型的省域碳排放研究

本文基于空间面板STIRPAT模型对1996~2010年影响全国省域人均碳排放因素进行研究,结果表明:省域碳排放具有明显的正向空间聚群效应;人均产出、对外贸易、能源强度、能源结构等指标与人均碳排放之间存在正向关系;人口密度、城市化率、产业结构等指标表现出的更多是抑制碳排放的作用。建议:强化区域联防联控的大气污染防治工作机制;推进工业化、城镇化;调整能源结构、产业结构,走可持续绿色低碳发展之路;优化对外贸易结构,推进"走出去"战略。

Identifying risk issues and research advancements in supply chain risk management

The purpose of this paper is to investigate the research development in supply chain risk management (SCRM), which has shown an increasing global attention in recent years. Literature survey and citation/co-citation analysis are used to fulfil the research task. Literature survey has undertaken a thorough search of articles on selected journals relevant to supply chain operations management. Meanwhile, citation/co-citation analysis uses Web of Sciences database to disclose SCRM development between 1995 and 2009. Both the approaches show similar trends of rising publications over the past 15 years. This review has piloted us to identify and classify the potential risk associated with different flows, namely material, cash and information flows. Consequently, we identify some research gaps. Even though there is a pressing need and awareness of SCRM from industrial aspect, quantitative models in the field are relatively lacking and information flow risk has received less attention. It is also interesting to observe the evolutions and advancements of SCRM discipline. One finding is that the intellectual structure of the field made statistically significant increase during 2000-2005 and evolved from passively reacting to vague general issues of disruptions towards more proactively managing supply chain risk from system perspectives.
