Abstract. This paper reviews the literature on measurement error in the major US price indexes—the Consumer Price Index (CPI), the Producer Price Index (RPI), and the Gross Domestic Product (GDP) deflators. We take as our point of departure Triplett's, 1975, survey and focus on the studies of measurement error that have appeared since then. We review the problems of substitution bias, quality bias, new goods bias, and outlet substitution bias that are generally considered to be the main sources of error in price indexes. The bulk of the paper is devoted to problems in the CPI and PPI, as the GDP deflators tend to be based mainly on the components of these series. We find that there has been surprisingly little work on the problem of overall measurement error in any of these price indexes, and we conclude that there is very little scientific basis for the commonly accepted notion that measured inflation at 2 to 3 percent a year is consistent with price stability. 相似文献

In this paper a sufficient condition for the identifiability of finite mixtures is given. This condition is less restrictive than Teicher’s condition Teicher H, Ann Math Stat 34:1265–1269 (1963) and therefore it can be applied to a wider range of families of mixtures. In particular, it applies to the classes of all finite mixtures of Log-gamma and of reversed Log-gamma distributions. These families have been already studied by Henna J Jpn Stat Soc 24:193–200 (1994) using another condition, different from Teicher’s, but more difficult to check in many cases. Furthermore, the result given in this paper is very appropiated for the case of mixtures of the union of different distribution families. To illustrate this an application to the class of all finite mixtures generated by the union of Lognormal, Gamma and Weibull distributions is given, where Teicher’s and Henna’s conditions are not applicable 相似文献

Advertising and its effects have been debated for well over a century. In the last few decades a generally sceptical view of the benefits of advertising has been overturned by a series of academic advances in economics that detail a variety of ways in which advertising may affect the economy and society. This academic work has however been paralleled by a growing popular and political opposition to advertising and its social effects. In this paper, the positive economic case for advertising is challenged by an assessment of the main channels of its influence and by a review of the associated empirical findings on its economic and wider impact. A policy response of limiting the tax deductibility of business advertising is explored. 相似文献

涨跌停板制度对期货市场价格发现过程及波动性的影响--基于上海期货交易所的实证研究 总被引:2,自引:0,他引:2
本文通过检验在出现涨跌停板之后一个交易日的期货价格及其波动性的变化情况,研究了涨跌停板制度对上海期货交易所期货价格变动的影响。研究结果显示,对不同的期货品种,涨跌停板制度的影响存在一定的差异,但总体而言,涨跌停板制度并没有起到防范价格过度反应和降低市场波动性的作用。相反,在一定程度上延缓了期货市场价格发现功能的发挥,增大了市场的波动性。 相似文献

This study applied linear and nonlinear causality tests and estimation models to investigate the efficiency of housing prices and volumes in the United States and its four major regions. The results of this study confirm that housing volumes can function as a price-discovery indicator. According to the nonlinear volatility of housing prices, this study verified numerous hypotheses. Housing returns can also influence housing volume. The results of this study imply that housing price efficiency can vary based on market conditions. Consequently, estimating the behavior of housing prices through a linear model can result in underestimating the information reflected by housing returns. 相似文献

Signed central α-moments of integer valued rv with decreasing density are considered. These are all positive if α≥3/2. We state sharp universal bounds on α depending only on the expectation of the random variable. For special cases the bounds are also evaluated numerically. 相似文献

中国工业部门的能源价格扭曲与要素替代研究 总被引:5,自引:0,他引:5
针对以往关于中国能源替代问题的研究未考虑价格扭曲因素的不足,本文以超对数成本函数为基础,对中国工业部门要素价格扭曲进行测度,并计算要素自价格弹性及要素间替代弹性。研究发现,能源的相对价格存在严重扭曲;能源自价格弹性在2004年前为正,其原因是价格管制与市场不完善阻碍了其调节功能的发挥;资本与能源间并不存在确定的替代关系,劳动与能源间在近期表现为替代关系,而其他投入与能源间表现为互补关系。本文最后根据实证研究结果提出三点政策建议。 相似文献

招标最低限价与公开保留价对防范串谋的共同作用 总被引:1,自引:0,他引:1
本文从防范投标人串谋的角度出发,将招标中的最优公开保留价和最低限价两种方式结合起来,通过一个离散的博弈模型,分析了第二价格密封招标中最低限价和公开保留价在防范串谋中的共同作用,经过研究发现最优公开保留价和最低限价对防范串谋方面所起作用,依赖于投标人的价值分布以及出现的可能性,另外还与投标人进行平行串谋时的成本有关。 相似文献

中国房价与地价关系的多用途视角研究 总被引:4,自引:0,他引:4
本文首先在保证土地与房产用途一致的基础上,选取中国1998年第1季度到2008年第3季度7组房价与地价指数,然后运用协整关系检验和Grangner因果关系检验技术分析每组房价与地价间的关系,并揭示这些关系在2002年7月1日土地招拍挂出让方式改革生效前后的变化.结论表明:①长期内房价与地价相互影响,且存在均衡机制;②短期内,从综合层面看,房价与地价两者互为因果,但从分阶段分用途看房价变动更多地决定地价变动;③土地出让方式改革对房价与地价关系影响并不大. 相似文献

论审计价格及其市场化导向 总被引:1,自引:0,他引:1
人们对审计收费认识上的偏差,注册会计师独立性缺失、审计价格难以反映审计市场的供求状况,审计主体无法自主定价,审计价格普遍偏低,价格机制对审计市场供求的调节作用无法发挥,这些问题严重影响审计市场的建立与健全和注册会计师行业的发展。本文认为,必须要改进现行审计收费制度,明确树立审计服务的盈利性观念,按照市场规律而非行政手段规范审计价格,确定审计价格时要遵循市场化原则。 相似文献

中国的房价与地价:理论、实证和政策分析 总被引:55,自引:0,他引:55
严金海 《数量经济技术经济研究》2006,23(1):17-26
本文采用四象限模型、格兰杰因果检验和误差修正模型等分析方法,从理论、实证和政策等方面对中国房价与地价关系以及市场结构和政府供地方式的转变对二者关系的影响进行系统、深入地研究,并对进一步规范房地产市场秩序,理顺地价和房价形成机制等提出政策建议。研究结果表明,短期内房价决定地价,长期内二者相互影响。与协议出让方式相比,土地招拍挂出让通过促进土地市场的买方竞争、降低房地产增量市场的垄断性,在显化土地价格的同时,降低了地价对房价的影响程度。 相似文献

Abstract. This survey focuses on government efforts to curb the use of undesirable goods, notably tobacco products. We synthesize the economics literature and examine the effectiveness of government curbs on tobacco consumption through non‐price controls (such as bans on cigarette advertising, health warnings, and workplace smoking bans) and price measures (or higher prices through higher taxes). This literature review is unique in that we do not merely aim to provide a summary of the literature. Rather, our main focus is to draw conclusions from the literature regarding the effectiveness of alternate policy measures across countries in checking smoking and to provide directions/suggestions for extending the scope of government intervention to other tobacco products. 相似文献
