巴拉萨-萨缪尔森效应假说:研究进展及其启示

现有文献分别从引入需求方传导机制,引入不完全市场竞争框架,完善经济增长与实际汇率升值的传导机制,以及引入一系列宏观经济变量四方面对巴拉萨-萨缪尔森效应假说进行了修正和完善。但对两部门的划分、生产率的选择以及计量检验方法的运用,仍存有争论,包括人民币实际汇率在内的绝大多数检验结果为巴拉萨-萨缪尔森效应的存在提供了支持的证据,不过也有一些检验对其提出了质疑。在研究我国经济增长与人民币实际汇率的调整和变动趋势中,应结合我国实际国情,对传统的巴拉萨-萨缪尔森效应假说进行拓展,从而对人民币实际有效汇率是否具有巴拉萨-萨缪尔森效应进行实证分析。     

人民币实际汇率与中国两部门生产率差异的关系——基于巴拉萨—萨缪尔森效应的实证分析

长期实际汇率主要取决于经济的供给面,即生产率的变化,这一思想体现在巴拉萨—萨缪尔森效应的模型中。文章从巴拉萨—萨缪尔森效应的理论出发选择合适的计量模型,然后以制造业和服务业分别表示贸易品部门和非贸易品部门,通过差分回归模型和协整检验来分析人民币实际汇率与中国两部门间生产率差异之间的关系,回归结果符合巴拉萨—萨缪尔森效应的结论。在1980~2004年间,人民币实际汇率的变动趋势与中国两部门间的生产率差异变化趋势基本相符:非贸易品部门生产率提高幅度大时,人民币趋向于贬值;而贸易品部门生产率提高幅度大时,人民币实际汇率趋向于升值。     

我国两部门劳动生产率增长及国际比较（1978-2005）——巴拉萨-萨缪尔森效应与人民币实际汇率关系的重新考察

依据巴拉萨-萨缪尔森效应假说，一国经济追赶伴随的可贸易部门劳动生产率的“相对相对增长”会派生本币实际汇率升值趋势。本文对改革开放以来我国可贸易与不可贸易部门劳动生产率各自增长、相对增长、国际比较增长等指标进行系统估测，发现上述结构性生产率指标与人民币实际汇率之间的关系存在与巴拉萨-萨缪尔森效应假说推论一致的经验证据；利用人均或劳均产出等总量性生产率指标检验这一理论对人民币实际汇率的解释力，则存在理论假说变量与度量指标选择不兼容的问题。     

汇率的非线性波动与巴拉萨--萨缪尔森效应

将非线性平滑转移模型与巴拉萨-萨缪尔森效应相结合,使用实际汇率对相对生产率进行回归,并在回归残差的基础上建立STAR模型。结果显示残差存在非线性波动,并且具有两个转换函数的STAR模型能够较好地反映残差的非线性波动特征。证明交易成本、市场参与者的异质性等因素影响了人民币汇率的形成,同时也说明巴拉萨-萨缪尔森效应影响了人民币实际汇率的均衡值。     

长期经济成长与实际汇率演变

巴拉萨—萨缪尔森效应对一国经济成长过程中劳动生产率追赶与实际汇率变动之间联系提出了理论推测。本文介绍巴拉萨—萨缪尔森效应假说理论内容和经验研究文献,利用国别截面数据与时间序列数据考查其主要经验证据。本文还讨论了巴拉萨—萨缪尔森效应假说对研究人民币实际汇率问题的借鉴意义。     

巴萨效应角度下的人民币升值与通货膨胀并存现象分析

2005年人民币汇率改革之后,人民币汇率经历着持续的升值,与此同时,我国国内物价持续走高,形成了人民币升值与通货膨胀并存的局面.巴拉萨-萨缪尔森效应解释了我国实际汇率变动的原因,实际汇率的变动是二者并存的主要原因.     

我国两部门劳动生产率增长及国际比较(1978-2005)-巴拉萨萨缪尔森效应与人民币实际汇率关系的重新考察

依据巴拉萨萨缪尔森效应假说,一国经济追赶伴随的可贸易部门劳动生产率的“相对相对增长”会派生本币实际汇率升值趋势。本文对改革开放以来我国可贸易与不可贸易部门劳动生产率各自增长、相对增长、国际比较增长等指标进行系统估测,发现上述结构性生产率指标与人民币实际汇率之间的关系存在与巴拉萨萨缪尔森效应假说推论一致的经验证据;利用人均或劳均产出等总量性生产率指标检验这一理论对人民币实际汇率的解释力,则存在理论假说变量与度量指标选择不兼容的问题。     

生产率、消费需求与实际汇率的决定——基于发展中国家（或地区）的经验证据

生产率增长、消费需求变动、国际收支状况等经济基本面因素是影响实际汇率变动的重要因素。通过对22个发展中国家和地区进行实证研究后发现,消费需求的变化对实际汇率的决定有着明显的作用,消费需求上升将使得实际汇率升值,下降将会使得实际汇率趋于贬值。虽然巴拉萨一萨缪尔森效应存在,但是作用并不明显。在我国,长期消费需求不足是导致人民币实际汇率持续走低的重要原因,虽然巴拉萨一萨缪尔森效应在我国也存在．但是人民币实际汇率仍然长期被低估。     

人民币实际汇率与中国经济增长的关系研究——基于边限检验法的巴拉萨-萨缪尔森效应检验

以Faria和Leon—Ledesma简化的巴拉萨-萨缪尔森模型为基础,运用Pesaran、Shin和Smith的边限检验法实证分析了1980—2007年期间人民币实际汇率与中国经济增长之间是否存在长期稳定关系。研究发现：改革开放以来,中国经济增长并没有伴随着人民币实际汇率的升值,巴拉萨-萨缪尔森效应在中国不成立。产生这一结果的原因在于：对高估的汇率进行贬值是中国经济高速增长的前奏,非市场化的劳动力市场阻断了BS效应中价格传递机制的发生。但是,如果中国经济保持较高的增长率,人民币实际汇率在长期中将经历一个升值过程。     

理解中国的实际汇率:一价定律偏离还是相对价格变动?

本文利用1997年1月至2010年9月的数据对人民币实际汇率进行分解,发现可贸易品偏离一价定律因素可以解释实际汇率波动的60%—80%,而可贸易品与不可贸易品之间的相对价格波动只能解释实际汇率波动的20%—40%。这意味着研究人民币实际汇率需要更多地从可贸易产品出发,不应仅仅强调国内不可贸易品与可贸易品的相对价格变化。进一步的研究发现,可贸易品因素对于解释人民币实际汇率占主导的结论,与中国相对于其他国家的经济体发展阶段有关。但是,上述结论并不意味着传统的"巴拉萨-萨缪尔森"效应失灵。事实上,当在计量回归中控制可贸易品偏离一价定律因素以后,巴萨效应在中国显著成立。只不过,相对于可贸易品偏离一价定律因素,巴萨效应对实际汇率波动的影响是次要的。     

John Stuart Mill's Theory Of Justice

John Stuart Mill has traditionally been portrayed as self-contradictory and failing to construct a unified social theory. Recent scholarship, however, has challenged this view, finding Mill's work to be creatively synthetic in bridging the antinomies inherent in liberal democratic thought. This revisionist interpretation of Mill is advanced by an understanding of his theory of justice and its role in shaping his policy positions on issues such as welfare, education, voting rights, property rights, taxation, government intervention, and the future of capitalism.

John Stuart Mill's Theories of Wealth and Income Distribution

Although he was much influenced by David Ricardo when he wrote the classical part of his Principles , John Stuart Mill was not a Ricardian when he penned his theories of wealth and distribution. They are based on a triple foundation. First, a belief that economics is a moral discipline. Second a theory of custom-driven human behavior. Third, an empirically formed conviction that the institutions of state, education and business cooperate to structure the distribution of income. On the basis of these presuppositions, Mill formulated 1) an institutional theory of the formation of human and non-human wealth and 2) an even more institutional theory of distribution demonstrating how the aforementioned institutions malignantly skew the distribution of income to the advantage of the propertied classes and to the extreme disadvantage of the working class. As a social economist, Mill recommended institutional reforms designed to eradicate the poverty of the working class.     

Toward a Phylogenetic Reconstruction of Organizational Life

Synopsis Classification is an important activity that facilitates theory development in many academic disciplines. Scholars in fields such as organizational science, management science and economics and have long recognized that classification offers an approach for ordering and understanding the diversity of organizational taxa (groups of one or more similar organizational entities). However, even the most prominent organizational classifications have limited utility, as they tend to be shaped by a specific research bias, inadequate units of analysis and a standard neoclassical economic view that does not naturally accommodate the disequilibrium dynamics of modern competition. The result is a relatively large number of individual and unconnected organizational classifications, which tend to ignore the processes of change responsible for organizational diversity. Collectively they fail to provide any sort of universal system for ordering, compiling and presenting knowledge on organizational diversity. This paper has two purposes. First, it reviews the general status of the major theoretical approaches to biological and organizational classification and compares the methods and resulting classifications derived from each approach. Definitions of key terms and a discussion on the three principal schools of biological classification (evolutionary systematics, phenetics and cladistics) are included in this review. Second, this paper aims to encourage critical thinking and debate about the use of the cladistic classification approach for inferring and representing the historical relationships underpinning organizational diversity. This involves examining the feasibility of applying the logic of common ancestry to populations of organizations. Consequently, this paper is exploratory and preparatory in style, with illustrations and assertions concerning the study and classification of organizational diversity.     

Information infrastructure: Who builds broadband networks?

This paper examines the essential difference between the U.S. and Japan, when one considers information infrastructure. There are seven perception gaps between the U.S. and Japan concerning Information Infrastructure policies. These gaps must be understood in order to compare the countries' governmental policies in this area. In looking at the present circumstances, the essential question to answer concerns who is to build, own and operate the network(s) of the infrastructure. Liberalization is certain to be a central factor in the ongoing telecommunications debates. Now that customers have had a taste of the liberalized market-place, the movement toward more open markets will be difficult to stop. When considering options, it is necessary to pay close attention to standardized network access and the increasingly important role software plays. These issues are causing us to take a new approach to the traditional role played by regulators. They also force a closer look at the appropriate structure of utility companies. This paper addresses the above issues in hopes of stimulating dialog on the new telecommunications infrastructure paradigm.     

海岛地区产业演替及资源基础分析--以舟山群岛为例

改革开放以来,舟山市产业构成发生了显著变化,其经济发展过程可以划分为三个阶段。1992年前,是以产业结构渔业占绝对地位的单一结构阶段;1993—1998年,以旅游业为主的第三产业快速发展阶段;上世纪末以来,又进入了新一轮的经济发展时期,即工业产值比重快速增加阶段。根据海岛的自然资源基础和特点,在新世纪的经济发展过程中,舟山市应定位为生态型的港口旅游城市。以港口及临港工业为主导,以海岛旅游和海洋经济为特色,大力发展第二产业和第三产业。海岛地区的主导产业应体现海岛资源优势及区位优势,以集群性环保型产业为主。同时由于海岛地区淡水资源缺乏,主导产业也应着重选择低耗水型产业。     

风险视角下企业治理结构和研发创新——基于委托代理模型的研究

本文基于委托代理模型,从风险的视角研究企业治理结构对研发创新能力的影响。本文构建了一个包含创新活动的委托代理模型进行理论分析,利用动态DEA 模型测算创新能力,并使用2015-2018年我国上市制造业企业数据进行实证检验。实证部分检验了理论结论:委托代理问题不利于企业提升研发创新能力,且客观风险和主观风险厌恶会加剧该负面影响。基于此,本文认为上市企业应根据企业自身研发活动特点有针对性地改善企业治理结构,提出了适当延长代理人任期、推动股权激励计划、提升代理人的风险承担能力等建议。
