Using Forecasting Criteria to Identify Value Relevance in the Relationship Between Accounting Numbers and Market Value

We explain and demonstrate a disciplined and systematic approach to repeatable modelling using forecast criteria, in addition to the usual statistical estimation criteria, to identify value relevance in regressions of the market‐accounting relation. The method was used in Cooke et al. ( 2009 ). It is illustrated here in the case of a single firm over a 59‐year period. Market and accounting data for the U.S. firm Abbott Laboratories Inc. from 1955 are modelled using a testing‐down, error correction approach. Hold‐out samples of 10 to 15 years are used to assess forecasting performance relative to a random walk. Emphasis is placed upon the use of simple, directly observable and theory‐independent model variables that can be replicated with other sample data. In this case, logarithmic transformations of all variables have to be computed in order to achieve correct statistical specification, implying a multiplicative relationship in the raw data. The strongest cointegrating accounting variable with forecasting ability for Abbott's market value is earnings. The model parameters exhibit long‐run stability and the accounting regressor marginally improves forecasts of market value compared to a random walk, demonstrating ‘value relevance’.     

农村社会保障支出对农村居民消费的影响的实证研究

从社会保障对居民消费影响机制的微观基础出发,运用协整分析并建立向量误差修正模型对我国农村社会保障支出的消费效应进行了实证研究.结果表明,我国农村社会保障支出没有对农村居民消费支出产生促进作用.因此,应加快农村社会保障制度的改革,促进农村居民消费,拉动内需.     

An empirical analysis of international labour migration in the Philippines

This study empirically investigates the impact of economic, demographic, and political factors on the size of emigration from the Philippines. In 2007, overseas workers from the Philippines sent remittances in excess of US$14 billion annually to their families back home. Although these remittances are an important source of foreign exchange and play an important role in economic development, the determinants of emigration in the Philippines are not well established. A simple unrestricted error correction model of migration was specified and estimated using data spanning the period 1975–2005. Results indicate that the level of unemployment, adult literacy and population density are the key determinants of emigration in the Philippines. The result also indicates that government instability impacts negatively on emigration in the Philippines. The policy implications of the results are discussed.     

FDI、对外贸易与经济增长的协整性研究——以山东省为例

关于利用外资、进出口贸易与经济增长关系的研究一直以来备受关注,但近年来的研究大多致力于两者间关系的独立性研究,其结果往往会使得理论与实证研究的解释力受到影响。对于多个同阶序列变量之间是否存在长期稳定的均衡关系的研究,协整理论具有重要的应用,其既可充分利用信息资源,还有效避免了“伪回归”问题。另外鉴于不同区域问经济发展模式、发展水平的差异性,各经济要素之间的关系也不尽相同,本文采用山东省1984～2007年间24年的统计数据,对该省的外商直接投资、进出口贸易与经济增长之间的相互关系进行了协整性检验和误差修正模型分析,总结得到有关结论：山东省利用外资、进出口贸易与其经济增长之间存在长期均衡关系,但具有区别于其他地区的自身特点。最后,针对山东经济的协调发展提出了若干政策建议。     

影响中美贸易的诸因素分析

本文采用2001年1月～2008年12月样本,在双边贸易引力模型的框架下,采用协整分析、向量误差修正模型等计量方法,在汇率和中美两国GDP等影响因素基础上,分析中国垂直专业化对于中国对美出口、中国自美进口和中美贸易差额的影响。研究结果表明,中国垂直专业化程度不断加深促进了中国对美出口、抑制了中国对美进口,加剧了双边贸易的不平衡。     

中国输出了“通货紧缩”或“通货膨胀”?

本文首次采用最新发展的有向无环图等技术方法,对中国是否输出通货紧缩以及是否输出通货膨胀这一问题展开综合性、系统性的研究。研究结果表明,在通货膨胀的国际传递中,作为世界第一大经济实体的美国发挥着主导作用,与此同时,无论是在中国通货紧缩时期还是在通货膨胀时期,中国对各主要贸易伙伴国物价水平的冲击均十分微小,因此,中国并非全球通货紧缩或通货膨胀的引发因素。在此研究过程中,最新发展的有向无环图技术等方法的综合运用,在很大程度上增强了本文分析结论的可靠性与合理性。     

Benefits Of Communications Infrastructure Capital In U.S. Economy

In this paper we empirically estimate the contribution of the communications infrastructure to the growth of output and productivity at the dis-aggregate industry and at the aggregate economy levels. The estimated value of the marginal benefits or the shadow price of the communications infrastructure capital is positive in each of 34 industries representing the major industrial sectors of the U.S. economy. This effect captures network externality benefits and can be interpreted as a willingness to pay by each industry for communications infrastructure capital services over and above their direct payments for communications services. These results suggest that an increase in communications infrastructure capital services reduces cost in all the industries and as a consequence that of the entire economy. The relatively high value of estimated total marginal benefits for the aggregate economy indicates a high social rate of return to the investments in communications infrastructure.     

中国金融资产收益率与宏观经济相关性研究

基于Lamont设立的经济跟踪指标组合体系,选择1997年5月至2006年11月的数据构建了股市各项资产收益率与宏观经济指标之间的多元OLS回归模型(ETP)、向量自回归模型(VAR)、协整检验和向量误差修正模型(VEC),全面考察了我国股市资产收益率与宏观经济变量之间的互动关系。研究发现,OLS模型与VAR模型中资产收益率的回归系数大多不显著,虽然宏观变量和金融资产收益率存在长期均衡关系,但是这种均衡关系非常松散和不明朗。     

内蒙古农村信贷与经济增长关系的实证研究——基于1978～2009年内蒙古自治区数据的分析

本文基于1978～2009年内蒙古自治区农村人均贷款和农村人均GDP的数据,首先,分析了改革开放以来二者的变动趋势,发现二者都呈现"缓慢增长———波动增长———快速增长"的变动趋势;其次,运用协整检验证实二者之间存在长期均衡关系;再次,协整检验和误差修正模型结果表明长期和短期内农村人均贷款与农村人均GDP的关系均为正相关,弹性系数分别为1.30%和17.20%,当短期波动偏离长期波动时,误差修正项将以13.09%作用力做反向调整,促使非均衡状态恢复到均衡状态;最后,格兰杰因果关系检验表明内蒙古农村人均GDP产出和农村人均贷款额之间互为因果关系。     

税法总则立法的基本问题探讨——兼论《税法典》编纂

当前我国税收立法正在加快推进,单行税法有望近几年全面完成立法。制定单行税法只是落实税收法定原则的第一步,为了发挥税收在国家治理中的基础性、支柱性和保障性作用,呼应《民法典》的编纂实施,提高税收法律的体系化和科学化,实现税收治理法治化,有必要尽快制定对单行税法起统领作用的税法总则,并在此基础上编纂《税法典》。税法总则是税收领域的基本法、总则法、平衡法和总则编,应当处理好与《宪法》、财政法、行政法总则、《民法典》和《税收征管法》等法律的协调关系,以法律关系为主线确定立法架构,着力破解税收领域的基础性法律难题。要按照"两步走"的思路,汇聚万众智慧,吸纳中外法典精华,努力编纂一部展现我国智慧、体现时代特征、在国际上具有示范效应的《税法典》。
