涉他偏好理论研究评述

大多数经济学模型都是建立在自利人假定的基础上的。然而近年来,大量的实验经济学结果拒绝这种自利人的假定。在实验中,大多数参与者表现出利他、公平、互惠等涉他偏好。西方学者主要从三种不同的角度来解释涉他行为：第一,分配偏好模型,这类模型关注分配结果是否均等、公正、有效;第二,互惠偏好模型,这类模型认为关注他人是出于对他人的回报或报复;第三,未来合作偏好模型,这类模型认为关注他人是为了未来的合作,当存在合作前景时,人们将会更慷慨。对这三种涉他偏好的理论模型进行了综述与评价。     

从有限理性到适应性理性

“有限理性之父”西蒙以及行为经济学家卡尼曼等人对人类“理性不及”和偏离理性的非理性行为做过深入系统的描述,并卓有建树,但是他们并未阐释人类决策过程中如何对理性与非理性进行合理有效配置的内在机制。基于此,本文从认知和心智层面,提出了适应性理性的假设命题,探索性地构建了适应性理性理论的解释框架,以一个全新视角,深化了有限理性的思想和内涵,并运用其理论重新阐释了行为决策过程中的认知偏差和简捷启发式的合理性。本文认为人类的经济决策行为同样遵循“心智经济性”的原则。     

Bounded Rationality in Individual Decision Making

The main objectives of this paper are: (i) To give a pithy, opinionated summary of what has been learned about bounded rationality in individual decision making from experiments in economics and psychology (drawing on my 1995 Handbook of Experimental Economics chapter); and (ii) mention some promising new directions for research which would be included if that chapter were written today.     

Decision Theory without Logical Omniscience: Toward an Axiomatic Framework for Bounded Rationality

I propose modelling boundedly rational agents as agents who are not logically omniscient—that is, who do not know all logical or mathematical implications of what they know. I show how a subjective state space can be derived as part of a subjective expected utility representation of the agent's preferences. The representation exists under very weak conditions. The representation uses the familiar language of probability, utility, and states of the world in the hope that this makes this model of bounded rationality easier to use in applications.     

有限理性下中美投资者对财富和消费偏好的比较研究

投资和消费是人们最重要的经济决策,而投资和消费的选择是由对财富和消费的偏好决定的。在效用最大化的前提下,构建有限理性的效用函数,来比较中国和美国投资者对于消费和财富的偏好。研究的结果表明,相对中国人而言美国人是更加偏好消费的,而中国人更偏重于财富。这样的差异形成的原因可能在于中国的金融市场发达程度不如美国,中国的社会保障体系不如美国完善。     

Bounded Rationality in Principal‐Agent Relationships

We conducted six treatments of a standard moral hazard experiment with hidden action. The behavior in all treatments and periods was inconsistent with established agency theory. In the early periods, behavior differed significantly between treatments. This difference largely vanished in the final periods. We used logit agent quantal response equilibrium (LAQRE) as a device to grasp boundedly rational behavior and found the following: (1) LAQRE predictions are much closer to subjects' behavior in the laboratory; (2) LAQRE probabilities and experimental behavior show remarkably similar patterns; and (3) including social preferences in LAQRE does not better explain the experimental data; (4) LAQRE cannot explain the contract offers of some players who seem to choose some focal contract parameters.     

有限理性、信息不对称与企业并购模型

本文基于有限理性与信息不对称框架，建立了一个企业并购的一般性信号博彝模型。模型表明，股权并购交易价格受目标企业资产质量、造假成本、并购企业调查成本、并购市场调查效率及买卖双方机会成本等因素的共同影响。建立高效、公平的市场体系，大幅度提高造假成本或建立完备而高效的信用体系，具有显著而理想的效果；足够大的造假成本或市场调查的高效率不仅可以保证市场配置资源的效率而且可以保证最好的交易公平性；但在一个不具有高效而完备信用体系且对造假者缺乏严厉惩处机制的市场里。改进并购市场调查效率或小幅提高造假成本反而可能对市场配置资源的效率形成伤害。     

Task Routineness and Trade Policy Preferences

Understanding the formation of individual trade policy preferences is a fundamental input into the modeling of trade policy outcomes. Surprisingly, past studies have found mixed evidence that various labor market and industry attributes of workers affect their trade policy preferences, even though recent studies have found that trade policy can have substantial impacts on workers' incomes. This paper provides the first analysis of the extent to which task routineness affects trade policy preferences using survey data from the American National Election Studies. We find significant evidence that greater task routineness leads workers to be much more supportive of import restrictions, consistent with recent evidence on how trade openness puts downward pressure on employment and wages for workers whose occupations involve routine tasks. In fact, other than education levels, task routineness is the only labor market attribute that displays a robust correlation with individuals' stated trade policy preferences. We also provide evidence that there are some interactions between the economic and non‐economic factors in our study. For example, women's trade policy views are much more invariant to their labor market attributes than men, suggesting that women's views on this issue are driven more by personal and ideological beliefs than men.     

Bounded Rationality in Economics: A Game Theorist's View

In this paper, we argue that it is essential to incorporate bounded rationality into game theory. Game theory has been applied to aspects of economics such as industrial organizati on on the basis of the naive interpret ation of game theory, which requires players to be ideally rational in an extremely unrealistic way. We stress the importance of establishing the perceptive interpretation of game theory by taking boundedly rational players' inductive reasoning processes into account. We explain my recent work, Matsushima (1997), which shows that the subjective games perceived by players in the long run are entirely different from the true objective game, and are trivial games in the sense that there exists a strictly dominant and subjectively Pareto-efficient strategy profile among the set of pure strategy profiles.

Environmental and Societal Attitudes to Working Hours in Gendered Perspective: Patterns,Preferences and Policy

ABSTRACT

This article begins from the premise that environmental degradation is a profound and present threat and that work time reduction–with an associated reduction in consumption–is one of a number of strategies that can be adopted to combat it. As a precursor to looking at how such policies can be supported, our research questions whether environmental attitudes are congruent with work time patterns and preferences. Our initial hypothesis was that those who care most for the environment would work fewer hours than those who exhibit lower levels of environmental concern, and prefer to do so. However, contra our expectations, our empirical analysis of the European Social Survey shows that those who state they care most about the environment are more likely to work longer hours, and prefer to do so. Overall, men tend to be less concerned about the environment, and work longer. Caring responsibilities, in contrast, fall disproportionately on women. We argue that this reflects traditional gender roles that are a residual from the social norm of the male breadwinner model. Given work time reduction as an environmental policy, the task is to influence preferences and ‘green’ human behaviour, especially among men.     

基于环境成本的比较优势理论及政策启示

在李嘉图模型中,将环境成本用追加的劳动投入来衡量,发现环保技术及环境成本对比较优势格局的修正.在H-O模型中,假定环境作为一种生产要素,则所形成的比较优势建立在包含环境资源真实价格的基础之上.社会环境成本与企业环境成本的差额,使"显示的比较优势"有可能偏离真实的比较优势,从而损害效率与公平.因此,要鼓励清洁技术创新,并通过制度变革来推进环境成本内部化.     

有限理性视角下知识产权质押贷款风险形成、评估与检验

创新型企业面临的信贷配给等融资约束已为经验研究所证实。中国政府为解决该问题,制定了知识产权质押贷款融资等政策并在实施后取得了阶段性效果,但后续的贷款风险正在形成和积累。借助有限理性理论解释知识产权质押贷款风险的形成机理是一种新尝试。同时,运用中国早期专利质押贷款试点数据,基于有限理性理论对知识产权质押贷款风险进行评估与检验。研究结果能够为检验、完善和改进中国知识产权质押融资政策提供经验依据。     

Public Policy with Endogenous Preferences

Public policy may influence norms and preferences. By altering the payoffs associated with different preferences, public policy may influence the distribution of these preferences in the population. Such interdependence between policy and preferences may limit (or enhance) the effectiveness of different policies. We demonstrate this idea with a simple model of subsidizing contributions to a public good. While the short‐run effect of such a subsidy will be an increase in the overall contribution, the subsidy triggers an endogenous preference change that results in a lower level of contribution to the public good, despite the explicit monetary incentives to raise that level.

Sustainability Policy and Environmental Policy

A theoretical, representative‐agent economy with a depletable resource stock, polluting emissions and productive capital is used to contrast environmental policy, which internalises externalised environmental values, with sustainability policy, which achieves some form of intergenerational equity. The obvious environmental policy comprises an emissions tax and a resource stock subsidy, each equal to the respective external cost or benefit. Sustainability policy comprises an incentive affecting the choice between consumption and investment, and can be a consumption tax, capital subsidy or investment subsidy, or a combination thereof. Environmental policy can reduce the strength of the sustainability policy needed. More specialised results are derived in a small open economy with no environmental effects on utility.     

有限理性、规范内化与利他行为:一个演化视角

本文沿着有限理性的理论进路,通过规范内化对利他行为做出一个解释。以往的理论通过规范提供的外在奖惩解释利他行为,但无法解释在外在奖惩不存在的情况下出现的纯利他行为。本文认为,这些利他行为可以通过规范内化来解释,而后者则是有限理性的一个自然结果。为了阐明规范内化如何产生,本文给出了一个形式化的复制者动态,其结果表明,在考虑有限理性的前提下,社会交往越复杂,人类处理复杂性的认知能力越有限,规范内化出现的可能性就越大。针对复制者动态模型的局限,本文还运用基于行为主体建模对规范内化过程进行了模拟。模拟结果显示,当人类理性计算能力相对于社会生活的复杂程度越小,规范内化出现的可能性越大,该结果与之前分析结论一致。本文的分析结果再次支持了Herbert Simon对利他行为的解释,即利他行为是人类有限理性的结果,虽然利他行为自身减少个体适应性,但由于它是规范内化所产生的一个自然结果,所以利他行为因为规范内化所具有的适应性而留存。
