从经济理性到有限理性:经济学研究理性假设的演变

"经济理性"是经济学的传统研究假设,却因背离现实而受到质疑.基于行为人稀缺的心理资源和系统固有的不确定性而产生的"有限理性"正逐步取代"经济理性"成为经济学研究的理性假设.不同的理性观点可以从决策的视角得到系统地解释和比较.并且,随着理性假设的演变,经济行为的决策标准也相应从单一静态最优向多元动态平衡转变.     

Bank loan versus financial lease: how do traditional and innovative approaches within the banking sector influence economic growth? A comparative analysis between the US and China

ABSTRACT

The argument over the effects of financial structures on economic growth remains unsettled. This study, therefore, compares the dynamic correlation and lead–lag relationship between the different financial approaches within the banking sector (that is, traditional bank loans versus innovative financial leasing) and economic growth. We employ a continuous wavelet analysis using time-series data from 1982–2017 from the US (the world’s largest developed country) and China (the world’s largest developing country). The empirical results show that (1) episodes of significant correlation usually emerge during periods of reform, crisis or policy implementation; and (2) in China, traditional banking promotes economic growth in the long term, while the real economy only imputes the evolution of banks during critical economic reforms in the short term. Meanwhile, financial leasing could only promote the development of the real economy under suitable regulation; and (3) in the US, before the crises, the irrational growth of the real economy could increase bank assets, while during the crises, the traditional banking approach harms economic growth, and after the crises, financial leases play an important role in recovery. Therefore, we suggest that policymakers should establish adequate policies and regulations to solve the situation.     

企业业绩评价:会计收益与经济收益的博弈

本文在对传统经济收益和会计收益的基本内涵及现时外延分析的基础上,阐述了传统收益的特点和在当前经济环境中遇到的挑战,从经济收益与会计收益选择的博弈与修正中,认为会计学中全面收益理想内涵是与经济学收益完全契合的概念,是经济收益与会计收益博弈过程中达到和谐和统一。同时在分析美英等发达国家的全面收益报告模式的基础上,依据现行经济环境和会计计量条件,提出具有中国特色的全面收益表报告模式。     

经济辐射理论与我国经济发展战略构想

辐射既表现为自然界不同物体间的能量相互传递，也表现为人类社会资源的互相流动。经济辐射理论既可以深化我们对扩大开放的新认识，也可以说明区域、产业等经济发展中的非均衡到均衡过程。     

Income inequality, democracy and growth reconsidered

Persson and Tabellini (Persson, T., Tabellini, G., 1992a. Growth, distribution and politics. Eur. Econ. Rev. 36, 593–602; Persson, T., Tabellini, G., 1992b. Growth, distribution and politics. In: Cukierman, A., Hercowitz, Z., Leiderman, L. (Eds.), Political Economy, Growth, and Business Cycles. MIT Press, Cambridge, MA, pp. 3–22; Persson, T., Tabellini, G., 1994. Is inequality harmful for growth? Am. Econ. Rev. 84, 600–621) as well as Alesina and Rodrik (Alesina, A., Rodrik, D., 1992. Distribution, political conflict, and economic growth. In: Cukierman, A., Hercowitz, Z., Leiderman, L. (Eds.), Political Economy, Growth, and Business Cycles. MIT Press, Cambridge, MA, pp. 23–50; Alesina, A., Rodrik, D., 1994. Distributive politics and economic growth, Q. J. Econ. 109, 465–490) have argued that income inequality reduces economic growth rates among democracies because it promotes distributional struggles. In this paper I question the supportive evidence for a number of reasons. Measures of income distribution and democracy are unreliable and permit only very tentative conclusions. Changes in data sources or recoding of some influential cases affect results. It is questionable whether equality effects on growth apply only within democracies, as a median voter interpretation of this relationship should make one expect. The general idea that distributional struggle hurts the growth prospects of nations, however, receives some empirical support.     

中国农村土地制度变迁:一个产权的视角

农地制度历来是中国农村变革的关键,其要义在于产权。本文从产权角度对建国后中国农地制度变迁作了简要分析。作者认为,产权的界定与实施决定着产权的经济绩效。土地改革以来各种农地制度创新形式的不同经济绩效都与产权清晰程度和实施机制有关。     

高校经济合同审计工作的探索

随着社会改革的不断深入和经济的高速发展，各高校对基础设施和教学科研等的资金投入也相应大幅度增加，需要签订的经济合同也越来越多。如何在复杂的环境中做好经济合同审计工作，成为高校审计人员在审计工作中遇到的新课题。     

分工差异与二元经济结构的形成

分工程度包含着部门因组织方式不同而导致的生产率差异,它可以为二元经济结构对立提供一个分析起点。本文构建了一个逐次放松条件的新兴古典经济学模型,从分工角度解释二元经济结构的形成。模型显示:二元经济结构反差源于部门个人专业化水平、迂回生产程度和产品种类数的不同,二元经济结构是两部门分工水平差异的产物,此判断得到了实证分析的支持。从分工角度出发,可以对中国二元经济结构问题形成更深刻的理解。     

注册会计师的角色认识与监管中的难题思考

从审计市场的供需两方来看,作为以提供审计服务换取收入的注册会计师,不可避免地有着“经济人”的共有特征——追求自身利益最大化,但同时,由于需求方信息使用者的广泛性,注册会计师实际上又肩负着维持市场秩序的社会责任,这正是注册会计师比其他提供劳务的行业受到更多限制的原因所在。从中关独立审计的发展轨迹可见,为了使注册会计师担当好其应有的社会角色,单靠市场或政府都是不可行的,作为公众利益的代言人——政府,如何合理把握市场与政府的界限,做好市场主体权利的配置是各国政府共同面临的难题。     

从福利经济学的角度看生态系统服务功能

生态系统服务功能与人类福利之间存在着密切的联系。深入认识生态系统服务功能与人类福利之间的相互联系与相互作用,对于保护和持续利用生态系统服务功能,提高人类的福利,促进经济社会的可持续发展具有重要的意义。本文基于联合国“新千年生态系统评估”(Millennium Ecosystem Assessment,MEA)项目的最新成果．系统分析了生态系统服务的内涵,从福利经济学的角度分析了生态系统服务与人类福利之间的关系,探讨了恢复和提高生态系统服务功能的主要措施。
