BQ分解在核心通货膨胀中的应用研究

文章对Blanchard and Quah趋势分解（BQ分解）在核心通货膨胀中的应用进行了深入的研究,并针对其在应用中所存在的问题提出相应的解决方案。 BQ分解是根据菲利普斯曲线理论发展而来的,主要用于对多维变量的趋势分解。研究表明,两维var模型的BQ分解通常是充分可解的。但是多维BQ分解由于自身的结构性原因,并不能保证一定可解出有意义的实数解。文章也证明了文献中所提出为了解决该问题的Cholesky分解,其与BQ分解相互矛盾而不可采用,所以文章推荐采用校准的方法。实证表明,由校准BQ分解所得到的核心通货膨胀完全满足理论和实践对它的要求,能够预测CPI指数的发展趋势,所以作为解决多维BQ分解无法正常求解时的备选方法,校准是一种便捷而有效的方法。     

信用评级高估与融资的所有制歧视——基于中国公司债的数据

为了分析发债主体所有制性质对公司债发行定价影响的作用机理,从信用评级高估的假设出发,将所有制性质的定价作用区分为直接效应和间接效应,基于贝叶斯法则得出两个推断：评级高估会导致发债主体所有制性质对公司债发行定价的直接效应;高信用等级公司债发行定价会受到发债主体所有制性质的直接影响,低信用等级公司债则不然。通过对2007—2013年沪深两市公开发行的公司债进行实证分析,推断得到了验证。这些分析有利于剖析民营企业融资歧视的形成机制。     

基于状态空间模型的汇率和货币供给对通货膨胀影响的实证分析——基于央行资产负债表的视角

从分析人民银行资产负债表的变化出发,运用状态空间模型实证分析了2005年7月至2012年6月中国汇率和货币供给对通货膨胀影响的动态时变过程。研究结果表明:人民币汇率升值对通货膨胀有一定的抑制作用,但其效果较弱;货币供给对通货膨胀有较大的正向推动作用,货币供给的持续增加是人民银行资产负债表中资产方的外汇占款科目不断增加导致负债方的基础货币持续增加的结果。     

More Facts about Prices: France Before and During the Great Recession

Using microprice data, we document new facts on price rigidity in France: (i) each month 20.1% of prices are changed, which compares to 24.1% in the United States—excluding sales, however, the fraction of prices modified each month is about the same in France and in the United States (around 17%); (ii) the distribution of price changes is quite dispersed; (iii) the frequencies of price increases and decreases contribute a lot to inflation variations, and price increases are more frequent in January (even when sales are excluded); (iv) sales contribute significantly to the volatility of inflation but play a minor role in the transmission of macroeconomic fluctuations to prices; and (v) during the Great Recession patterns of price adjustment were only slightly modified.     

Housing and the Macroeconomy: Inflation and the Financial Accelerator

Three themes connecting housing and the macroeconomy are discussed. First, evidence is presented for the property market as one of the drivers of U.S. consumer price inflation. Second, key drivers of house prices are explained to account for the remarkable diversity of international experience. Finally, three potential links between housing, credit, and the financial accelerator are discussed. These are the consumption channel, the investment channel, and feedback between bad loans and risk‐spreads via the financial system—and how institutional differences between countries can explain the presence, absence and magnitudes of these linkages.     

基于风险选择与投资收益的外汇储备币种结构研究

随着外汇储备规模的不断增加,国家外汇储备投资的风险偏好亦会发生相应的变化。借鉴 J. H.Makin(1971)的方法,构建外汇储备币种结构配置理论模型,讨论在效用最大化的情况下,储备资产投资如何在安全性、流动性和盈利性三原则间进行权衡。假设外汇储备仅投资于美元和欧元两种币种资产,选取2000年初~2014年第三季度的10年期美国国债和欧元区公债季度数据,运用协整分析、格兰杰检验等方法进行的实证研究发现：储备货币在外汇储备中的比重与储备货币收益率及其三阶矩显著正相关,国家外汇储备投资总体而言是风险规避型的。     

我国通货膨胀过程的社会福利成本度量与经验分析

通过利用1994年至2006年之间的我国GDP、M1和名义利率的季度数据,采用协整检验和回归系数估计方法,获得我国长期货币需求函数,在此基础上对我国通货膨胀的社会福利成本进行了实证分析。实证结果表明,我国较高的通货膨胀率会带来比较大的福利成本,因此,当前通胀压力较大的时期,采取适当的宏观调控措施,将通货膨胀率控制在3%以下的低水平状态。     

The Euro Illusion in Consumers’ Price Estimation: An Italian–Irish Comparison in the Third Year of the Euro

The euro illusion is a transient phenomenon that consists of currency-related asymmetries in the intuitive judgment of product prices made by consumers. The results of a cross-country study in the third year after the introduction of the euro show a strong price estimation asymmetry in a country with an extreme exchange rate (Italy) and a weaker effect in a country in which the nominal values of the new and the old currency are much closer (Ireland). These results rule out proposed explanations of the euro illusion in price estimation that assume the sole influence of plausible anchors (reference prices stored in memory within the plausible price range), supporting instead accounts also endorsing the role of implausible anchors (reference prices outside the plausible price range). Beyond contributing to our theoretical understanding of the euro illusion, this research starts to unveil the interplay between structural factors (i.e., the currency exchange rate) and psychological mechanisms that produce long-lasting difficulties for consumers after a monetary changeover.

中国通货膨胀持续性的非对称特征研究--基于分位数自回归模型和分位数单位根的研究

基于1990－2013年中国月度CPI数据,本文通过运用分位数自回归模型和分位数单位根检验方法,研究了中国通货膨胀惯性的非对称特征,并分析了不同分位点上的通货膨胀惯性系数、单位根检验结果和半衰期。结果发现：中国的通货膨胀持续期存在明显的非对称特征,1998年之后通货膨胀持续性要显著低于1998年之前;相比于高通货膨胀水平,低通货膨胀水平上的通货膨胀持续性要显著降低。     

析我国外汇占款对冲策略

根据我国的经济运行情况,分析固定汇率、资本流动与货币政策自主的“三元困境”在我国的具体表现。指出在经常项目和资本项目持续顺差的情况下,货币政策与外汇储备增长的矛盾。说明为控制流通中的货币而被动进行的单向对冲操作的成本昂贵,并且是以牺牲货币政策自主为代价的,还易积蕴金融风险,酿致恶性后果。证实了外汇占款对冲策略的不可持久性,为此必须改革现行的固定汇率制度,并放松资本管制。
