计量经济学的地位、作用和局限   总被引:27,自引:1,他引:27  
目前,计量经济学和微观经济学与宏观经济学一起构成了中国高校经济管理类本科生和研究生必修的三门经济学核心理论课程。计量经济学在中国经济学界受到越来越广泛的关注,其方法与工具也在实证研究中被大量应用。本文将阐述现代计量经济学的基本思想和方法论,计量经济学在经济学研究中的地位、作用和局限性,计量经济学与数理经济学、数理统计学及经济统计学之间的差异,等等,并运用大量经济学和金融学中有代表性的实例说明计量经济学的应用以及在应用时应注意的若干问题。  相似文献

The authors taught financial concepts to students in 12th-grade economics classes, where one treatment was intensive in money management (MM) topics and the other was intensive in financial investment (FI) topics. Two control groups, consisting of 11th-grade students with no exposure to economics and 12th-grade economics students, received no treatment. Both treatment groups showed a 13 percentage point increase in test scores from pretest to posttest, while neither control group showed gains. Neither treatment group outperformed the other in the financial literacy test.  相似文献

In this article I discuss the potential role of agent‐based modeling techniques in development economics. Development economics has recently seen a strong rise of experimental evidence from the field and the laboratory. At the same time, there is a debate on how theory should adapt to this new approach and its findings. I argue in this paper that the agent‐based modeling approach is a promising complement to the traditional modeling techniques, as it can easily incorporate the non‐standard findings of the experimental literature. Moreover, I emphasize the opportunity of a mutually beneficial interplay between experiment‐based empirical research and agent‐based models.  相似文献

In ecological economics the debate on formalism and formalization has been addressed in the context of a lively discussion on ecological economics as a ‘post-normal’ (versus ‘normal’) science. Using ecological economics (EE) as a ‘seed’ journal and applying bibliometric techniques to all (2533) the articles published in EE from January 1989 to December 2009, we analyze the evolution of the field of ecological economics aiming to shed light on this debate. We observe the predominance (and increased relevance) of certain research topics: ‘Methodological issues’, ‘Policies, governance and institutions’ and ‘Valuation’. Moreover, ‘Collective action’, ‘Technical change and the environment’ and ‘Values’ stand as emergent themes of research. Finally, we note that ecological economics experienced an ‘empirical turn’ reflected in a shift away from exclusively formalized papers towards exclusively empirical and, to a larger extent, ‘formal and empirical’ ones. The combination of the prominent and emergent topics and the ‘empirical turn’ mirrors the increasing awareness among researchers in the field of the need to address a key specificity of ecological economics — the interdependence of the economic, biophysical and social spheres. On this basis, we argue that at least through the lens of EE, ecological economics has evolved towards a post-normal science.  相似文献

In this article, the authors illustrate the use of Bloomberg for analyzing topics in macroeconomics and monetary policy in economics and finance courses. The hands-on experience that students gain from such a course has many benefits, including deeper learning and clearer understanding of data. The authors describe goals and learning objectives, then compare Bloomberg with Federal Reserve Economic Data (FRED). In addition, they provide examples of how to use Bloomberg in the classroom, describe how to have students perform sector analysis, show how Bloomberg tools are useful for analyzing monetary policy, discuss how to use Bloomberg to analyze the financial sector, and illustrate the platform’s use in a case study.  相似文献

利用85个国家1989—2011年的跨国数据,实证检验不同收入水平下,金融结构对国家技术创新的影响差异。结果显示,高收入水平国家偏向于金融市场的金融结构更加有利于技术创新。基于新结构经济学理论思想,对该结果进行了解释:不同收入水平国家的创新结构不同,即自主研发和模仿创新的比例不同。从事自主研发和模仿创新的企业在风险特征、企业规模方面具有差异,这要求不同比例的金融市场和银行信贷与之匹配。由此,创新结构决定技术创新视角下的最优金融结构。因此,在特定发展阶段,存在与之相匹配的最能有效促进技术创新的金融结构。该结论强调了考虑发展阶段因素的必要性,为新结构经济学相关理论提供了新的实证证据,也具有明确的政策含义。  相似文献

Existing empirical evidence for the relevance of the β in modelling asset returns is mixed. Drawing on conditional tests of β first proposed by Pettengill, Sundaram and Mathur (1995) and extended by Bollen (2010), empirical evidence employing monthly data is presented that indicates that β is highly related to variability of asset returns but not to the level of asset returns. This result is consistent with the predictions of the market model but not with the predictions of the CAPM. It is concluded that β remains a useful construct in financial economics but may have a differing role in financial economics than the conventional wisdom asserts.  相似文献

改革开放特别是西部大开发以来,四川省在金融、经济增长方面都取得了重大成就.基于内生经济增长模型对四川金融发展与经济增长的关系的实证分析表明:四川省经济增长与金融发展存在正向关系且经济增长是金融发展的Granger原因;但储蓄转向于投资的比例与四川省经济增长之间是负相关关系且不存在Granger原因,这可以得出四川省金融发展滞后于经济增长的结论.因而四川省应大力发展金融产业,将成都建成西南金融中心.  相似文献

The frequent empirical failure of uncovered interest rate parity raises a question that has not been definitively answered: why do predictable excess returns on currencies persist in competitive currency markets? Supported by data from nine major currencies for 1978:08–2019:09, I provide a novel resolution to this enduring forward premium puzzle by building on the financial economics literature that explores the economic implications of limited access to capital markets. A liquidity shock, or the urgent demand for liquidity by credit-constrained arbitragers liquidating bond holdings, causes losses from sudden drops in bond prices. Arbitragers require a liquidity premium to compensate for potential losses that vary directly with the interest rate. It is this liquidity premium that explains persistent excess returns on currencies. I argue for policies favoring a low interest rate environment and macroprudential controls that ease liquidity constraints to increase the efficiency of international capital markets by reducing the liquidity premium.  相似文献

In this Australian Treasury seminar, I discuss the contributions that psychology could make to public policy formation via a new field: public policy psychology. Behavioural economics provides a precedent for my new field of public policy psychology. Unlike economics, psychology provides a solid scientific model of how individuals make decisions. I discuss shortcomings of economics in policy formation: model blindness, the focus on evidence supporting theories, the focus on markets, plus the importance of elements left out of conventional economic models (for example, irrational decision‐makers). I end by discussing two Treasury case studies: the mining tax and government responses to the Global Financial Crisis.  相似文献

文章运用新制度经济学的基本理论,以我国沪深两市A股上市公司2000-2006年的数据为样本,实证分析了金融发展促进经济增长的微观作用机制.研究发现,若债务比例增加1%,金融发展水平高的地区与低的地区相比,公司市场价值平均多提高[作者单位].54%,并且,债务融资与公司价值的正相关关系只在金融发展水平高的地区才存在.这表明,金融发展水平对债务治理作用的发挥有重要影响,公司所处地区的金融发展程度越高,债务治理的作用越强,越有利于提高公司的价值.  相似文献

While many heterodox economists hope that the recent financial crisis will lead to paradigmatic change in economics, we argue that path-dependent processes and institutional factors within the economic community hinder such a change. Focusing on the citation behavior of economists in heterodox journals in general and in Post-Keynesian journals in particular, we discuss structural reasons—connected to positive feedback mechanisms within the institutional framework of the economics discipline—for the marginalization of heterodox economic thought.  相似文献

金融发展与经济增长的关系是经济学的一个重要研究领域。选取1982—2008年为时间段,以湖南省为例对金融发展与经济增长的关系进行了实证研究,结果表明湖南省信贷存量、其他金融机构发展(除银行)与经济增长呈正相关关系,而货币存量与经济增长呈负相关关系。经济增长是其他金融机构发展的短期格兰杰原因,而存贷存量在长期上是经济增长的格兰杰原因。  相似文献

This paper contributes to the literature by investigating the relationship between financial development, economic growth and poverty reduction in Bangladesh using quarter frequency data over the period of 1975–2011. This issue is of importance for developing economics given the role of financial sector in mobilizing and allocating savings into productive investments. We use an innovative empirical approach based on ARDL cointegration with structural breaks. Our findings show that a long-run relationship between financial development, economic growth and poverty reduction exists in Bangladesh. Financial development helps to reduce poverty, but its effect is not linear.  相似文献

I develop a stylized model of endogenous growth in which the level of financial depth influences an economy’s long-run growth. Financial depth is defined within the model as the ease with which investors can issue equity in the market on new units of capital. I assume that agents differ in the cost of undertaking investment projects and that there is a fixed distribution of such costs across the population. I theoretically identify channels through which financial depth influences growth, both positively and negatively. When considering a specific distribution of costs, I show that the net effect of financial depth on growth is non-monotonic. It depends on the shape of the distribution, as well as the level or stage of financial depth. The results of this paper help to rationalize some findings in the recent empirical literature on the non-monotonic effect of financial depth on long-run growth. The model is even capable of obtaining a negative effect of excessive financial depth on growth, a result that is also found in the empirical literature.  相似文献
