Social Comparisons in Ultimatum Bargaining

Experiments are used to examine the effects of social comparisons in ultimatum bargaining. We inform responders about the average offer before they decide whether to accept or reject their specific offer. This significantly increases offers and offer‐specific rejection probabilities. For comparison, we consider another change in informational conditions: telling responders the total pie is $30—ex ante it was either $15 or $30—affects offers and rejection probabilities roughly as much. Our results are consistent with people’s dislike for deviations from the norm of equity but inconsistent with fairness theories, where people dislike income disparity between themselves and their referents.     

Does transparency of central banks communication affect credit market? Empirical evidence for advanced and emerging markets

This study examines the effect of the transparency of central banks communication on credit market. In particular, this study investigates how central banks’ effort to provide more detailed information about their objectives regarding the price stability (monetary policy transparency) and financial stability (financial stability transparency) policies are able to mitigate information asymmetry on credit market, through the net interest margin charged by the banks to engage in financial intermediation (credit spread). The findings denote central bank transparency is able to reduce the credit spread. Additionally, the evidence suggests the effect of central bank transparency on the credit spread is greater in emerging markets, where there is less information available on credit market. In brief, transparency in central banks communication is an important tool to mitigate the information asymmetry in the credit market.     

Green Business and Blue Angels

This paper presents a model of a monopolist'svoluntary overcompliance with legal environmentalstandards under asymmetric information about thefirm's environmental impacts. The key assumptions are:the existence of quality premia for environmentalsoundness, a positive but imperfect degree ofmonitoring, and adaptive consumer expectations.Conditions necessary for overcompliance to arise in aprofit-maximizing equilibrium are derived. The effectsof a third-party eco-labeling system are analyzed. Itis shown that the existence of an independent labelingauthority increases the likelihood of overcomplianceto be profit-maximizing. Moreover, firms might have anincentive to lobby for the introduction of such asystem. The effect of consumers' risk preferences andan instrument for preventing ``Greenwash' (companieslying about their environmental performance) is alsodiscussed.     

非线性定价的福利再分配效应研究——基于非对称双寡头市场的分析

较之"线性定价","非线性定价"在社会福利方面的优势被现有理论反复证明。在肯定"非线性定价"方式能够改进社会总福利的同时,指出并不是每一个市场主体的福利水平都能够通过"非线性定价"方式得到改进。通过建立模型、计算和比较分析,提出了在上述两种情况下,"非线性定价"可能会对特定的市场主体产生"福利剥夺",从而出现福利再分配效应。     

The effectiveness of R&D subsidies

In this paper, the effectiveness of R&D subsidies is analyzed in an oligopolistic model that we apply to the cases of international R&D competition and cooperation. We find that the existence of asymmetric information among firms on whether a rival (or partner) is being subsidized or not may play a key role in explaining whether subsidies are effective or not in increasing R&D investments. In particular, it is shown that if the existence of the subsidy is made public (e.g. because strict information release regulation about R&D subsidies is enforced) and depending on the strategic relationship between the firms’ R&D efforts, an R&D subsidy could even hurt the subsidized firm.     

Collaboration risk management in IT-enabled asymmetric partnerships: Evidence from telestroke networks

Information technology (IT)-enabled partnerships can unlock previously unattainable value propositions between organizations that have resource, capability, and other asymmetries by allowing larger organizations access to niche and local resources while providing smaller organizations access to enhanced resources and capabilities. However, recent studies have shown that many IT-enabled asymmetric partnerships often fail because the organizations do not effectively manage the involved collaboration risks. Most organizations focus on the strategic aspect of whether partners behave cooperatively or competitively, while paying scant attention to the operational aspect of bringing together partner contributions through coordination. To examine this problem, we report on a case study of two hub-spoke networks that used telemedicine to facilitate expertise sharing and decision making about stroke treatment at emergency departments in rural hospitals (spokes) based on information exchanges with remote neurologists at academic medical centers (hubs). As a result, we contribute to the inter-organizational information systems literature by explaining how organizations in IT-enabled asymmetric partnerships manage collaboration risks. We demonstrate how partners in such relationships perceive and approach strategic cooperation and operational coordination risks differently. We also explain how collaboration interactions change over time as the partners manage risks based on needs and resource endowments. Drawing on these findings, we provide guidance to organizations on how to manage sustainable IT-enabled asymmetric partnerships in general, and telestroke networks in particular.     

投资方与项目公司的委托代理博弈分析

项目投资中,投资人与项目公司之间存在着“委托-代理”关系。由于两者之间的信息非对称,导致了项目投资中道德风险的存在。借助信息经济学中的“委托-代理理论”建立了项目公司道德风险模型,定量的分析了如何通过设立约束机制使投资人实现利益最大化,得出了有利于提高投资人项目管理水平的分析结论。     

非对称信息下商业银行资本配置研究——基于PCA理论模型分析

资本配置是银行风险管理的核心,是决定银行竞争力的重要因素.经典的资本配置理论均以信息在银行内部各机构完全对称作为基本假设,忽略了总分行问的委托代理关系.鉴于此,本文借鉴PCA模型,在商业银行内部构建一套资本配置的优化机制,以提高银行资本配置的有效性.
