The effects of group composition in a strategic environment: Evidence from a field experiment

Recent theoretical and empirical studies have explored the effect of group membership and identity on individual decision-making. This line of research highlights that economic models focusing on the individual as the sole entity in the decision-making environment potentially miss critical features. This study takes this literature in a new direction by overlaying a field experiment onto a setting where groups have arisen naturally. Our experimental laboratory is large open air markets, where we are able to examine the effects of group membership on seller׳s collusive behavior as measured by prices and surplus allocations. This permits us to explore strategic implications of group composition. Empirical results illustrate the importance of group composition on pricing decisions, and show that deviations from Nash equilibrium are crucially related to group membership.     

金融监管的国际协作效应探索

金融监管的国际协调与合作始于19世纪末20世纪初，随着世界经济、金融的发展，其广度和深度不断变化。目前，经济金融全球化导致的国际经济金融关系的深刻变化，已使金融监管的国际协作成为国际经济协作的主旋律。但是，由于各国对协调时机、协调方式把握的不一，协调机制并不十分完善，加之金融监管国际协作本身存在诸多的障碍，使这种协作存在一些局限和不足。金融全球化对中国金融监管当局的综合监管与协调能力提出了更高的要求，了解并进一步认识金融监管国际协作的历程，有助于借助发达国家的经验，通过加强与国际经济和金融组织的协作，促进中国金融业的稳定、健康发展。

中韩贸易模式的变迁：从互补到竞争

对中韩贸易的大部分研究集中于双方的互补性，回避竞争。本文从双方进出口商品结构、在主要出口市场及在对方国内市场三个方面论述中韩贸易竞争的表现，然后从中国竞争力迅速提高、中韩出口结构趋同、未来科技发展重合、出口市场高度重叠等方面分析其中的原因，特别指出深层原因是发展模式相同，产业结构相似。最后提出建议：韩国首先要改变防范中国的心理，以合作代替对抗；在政府层面、产业层面和企业层面加强合作，并指出了优先的合作领域：石油开发、铁矿石采购、高新技术开发等。     

A theory of reciprocity

People are reciprocal if they reward kind actions and punish unkind ones. In this paper we present a formal theory of reciprocity. It takes into account that people evaluate the kindness of an action not only by its consequences but also by its underlying intention. The theory is in line with the relevant stylized facts of a wide range of experimental games, such as the ultimatum game, the gift-exchange game, a reduced best-shot game, the dictator game, the prisoner's dilemma, and public goods games. Furthermore, it predicts that identical consequences trigger different reciprocal responses in different environments. Finally, the theory explains why outcomes tend to be fair in bilateral interactions whereas extremely unfair distributions may arise in competitive markets.

Is corporate environmental disclosure associated with firm value? A multicountry study of Gulf Cooperation Council firms

Several studies have found a relationship between corporate social and environmental disclosure and firm value (FV) or accounting profitability. Where environmental disclosure has been the focus, though, only single-country studies have been published, and most of the previous research concerns the developed world. This study examines the association between corporate environmental disclosure (CED) and FV in the Gulf Cooperation Council (GCC) countries, where CED has been increasing from its previous low base. Findings from a multicountry sample of 500 firm-year observations using a 55-item unweighted environmental disclosure index suggest that CED is significantly and positively related to FV as measured by Tobin's Q (TBQ). The relationship is robust to using a weighted version of the disclosure index, individual countries and environmental disclosure subindices. Some evidence of a positive relationship between CED and return on assets is also found, but even where statistically significant, the relationship is much weaker than in the case of TBQ. For empirical and theoretical reasons, we recommend that future studies pay greater attention to market-based proxies, if possible, when investigating the value relevance of CED in both developed and developing countries. Our results suggest that both managers and policymakers in GCC countries should take a positive view of expanded CED.

Lineage-based heterogeneity and cooperative behavior in rural China

This paper investigates how lineages, the commonly found organizations in rural villages of China, affect people's intra- and cross-lineage cooperative behavior. We use data from the Chinese Household Income Project Survey 2002, which exclusively contains information about the lineage structure in these villages allowing us to classify three levels of lineage-based heterogeneity. Our identification strategy relies on the exogeneity of lineage-based heterogeneity. We find evidence that people in a village with higher lineage-based heterogeneity are less likely to exhibit reciprocity behavior within lineages or contribute to the provision of public goods that are jointly shared across lineages. The estimation results remain robust to the inclusion of various control variables and additional background characteristics. Finally, we examine a number of other economic outcomes and find that more homogenous villages do better than other types of villages.
