Nash implementation with an infinite-dimensional trade space

This paper deals with the problem of implementing the Walras correspondence via Nash equilibria, in exchange economies with infinitely many commodities and finitely many households with possibly non-ordered preferences. We explicitly construct a feasible mechanism enjoying some features, which have natural economic meanings. Under a fairly weak boundary condition, this game fully implements the Walras equilibria. If this condition is not fulfilled, our mechanism nevertheless implements the constrained Walras equilibria.

Embedded Enclaves: Cultural Mimicry and Urban Social Exclusion in Iran

This article argues that symbolic boundaries and their spatial manifestation into embedded enclaves have become new forms of urban social exclusion. Based on participant observation and interviews among lower‐ and middle‐/upper‐class residents in the city of Sari, Iran, the article analyzes how the poor's physical circulations in the city and their performances of class and status have led to an elite backlash, as the latter find more refined markers of social separation in an effort to bolster their own exclusivity. Social distancing through the denigration of the poor and the construction of embedded enclaves brings to the fore the class tensions that are temporarily masked by the urban poor's spatial practices and cultural mimicry. As an advanced form of codified status inequality, embedded enclaves rely on the poor's citywide circulations and on increasing inter‐class interactions in order to communicate difference. Embedded—rather than cordoned off—in prominent areas of the city, such enclaves function as a reminder to the poor of all they cannot have. The upsurge of such establishments in the wake of Iran's shifting economic environment represents an attempt to shore up social position and restore the status quo.     

A dynamic perspective: local interactions driving the spread of social networks

ABSTRACT

This study takes a micro standpoint to quantitatively verify the extent to which local interactions affect the expansion of dynamic social networks. By reviewing and synthesizing the theoretical literature in this article, we seek to establish a pragmatic analytical framework to capture the underlying functioning of local interactions. It then aims to produce findings on seven distinct marketing campaigns in which the real-world virtual communities offer intact time-series connections. In our considered cases, the firm-to-consumer interactivity plays a pivotal role in social media marketing while the customer-driven influence advances individual information transmission. The significant positive relationships demonstrate features of interactivity within subgroups including reciprocal edges and directed 3-cliques associated with the evolution of the virtual community by electronic word-of-mouth (WOM) of both firm-to-consumer and consumer-to-consumer interactions. More importantly, the attenuation of local interactions to a large extent leads to the cut-off point of the growth of the dynamic social network.     

考虑社会责任的异质有限理性制造商产量博弈均衡复杂动力学分析

通过考虑消费者剩余,企业利润中引入承担社会责任参数,建立了具有异质性有限理性的古诺寡头博弈竞争模型,分析利润相关参数对系统博弈均衡稳定性的影响,并进行了数值模拟。研究表明单方有限理性系统比双方有限理性系统稳定。产品成本超过一定阈值应避免产量竞争,可以通过承担社会责任,提升产品价格来增加利润,但当企业承担社会责任增加时,系统稳定性降低。此时降低调整产量的速度,观察竞争对手产量调整速度,避免系统进入混沌状态,失去最优产量优势。     

论社会资本对企业技术创新的影响

知识经济的迅猛发展,使企业技术创新更多地体现为一种动态的复杂的社会化知识创造过程。本文力图以企业社会资本理论为基础,从新制度经济学的角度分析了社会资本影响企业技术创新的内在机理。     

ESG表现与企业金融化——内外监管双“管”齐下的调节效应

以2011—2018年A股非金融、非房地产上市公司为样本,探讨环境、社会责任及公司治理（ESG）表现对企业金融化的影响效应。研究表明：ESG表现抑制了企业金融化,而企业内部监管会放大ESG表现对企业金融化的负向效应,外部金融监管则弱化了两者之间的负向关系。抑制效应、放大效应和弱化效应在环境、社会责任方面体现较为明显,而在公司治理方面不明显。进一步研究发现,ESG表现以及环境、社会责任能通过融资约束抑制企业金融化行为,融资约束在公司治理对企业金融化的影响中不具有中介作用;异质性分析发现ESG表现以及环境、社会责任对企业金融化的抑制效应在国有企业、研发能力较强企业中较为显著,而公司治理在非国有企业和研发能力较强的企业中表现出正向的金融化效应。研究结果丰富了ESG表现影响企业金融化的理论机制,为完善上市公司监管制度体系、夯实实体经济发展根基提供了依据。     

集群治理:社会资本价值量提升的手段

对纳税筹划问题的理性思考

纳税筹划近年来日益受到人们的关注,但国内研究多侧重于筹划策略和方法。本文试图从理论上对纳税筹划的必然性、可能性及其经济和社会效应进行较深入的探讨,完善纳税筹划的指导思想,纠正对其错误的认识。
