公众预期、通胀成因与经济波动牵扯

针对金融危机冲击下各国宏观经济政策所导致的新的世界经济波动,结合中国当前通货膨胀两难局面,运用古典模型中的二分法解构中国通货膨胀,得出名义变量引致了通胀的结论,并将古典增长模型与利率平滑规则有机结合,推断出现阶段通胀背景下仍应坚持适度从紧的货币政策规则,引导公众心理形成稳定的期望收入预期,才能真正意义上在稳定通胀的同时,形成社会理性消费预期,从而使扩大内需成为可能,这才是解决现阶段增长困境所在。

Degrees of tax indexation and nominal interest rates: Effects of inflation on incentives to save and invest

This paper examines the effects of inflation expectations on nominal interest rates, and incentives to save and invest under partial and complete tax indexation schemes. One would expect that a partially indexed structure would be better than a non-indexed system. However, this is not the case—it reduces the adverse effects of inflation on the incentives to save, but accentuates them on the incentives to invest. Moreover, a change from a non-indexed tax structure to a fully-indexed structure will, ceteris paribus, lead to lower equilibrium interest rates, whereas a switch to a partially indexed system will imply higher rates.

Inflation Developments and Perceptions after the Euro Cash Changeover

Abstract. This paper analyses the evolution of inflation and of consumers' inflation perceptions in the aftermath of the euro cash changeover. It finds that the cross‐country variation of food product inflation was dependent on the complexity of conversion rates, with statistically significant and economically sizeable effects especially for low‐priced items sold in midpriced stores. The paper also shows that cross‐country differences in the mismatch of perceived and actual inflation were linked to differences in the complexity of conversion rates. These results are in line with theories of finite information‐processing capacities on the side of consumers.     

On the real effects of inflation and inflation uncertainty in Mexico

We estimate an augmented multivariate GARCH-M model of inflation and output growth for Mexico at business cycle frequencies. The main findings are: (1) inflation uncertainty has a negative and significant effect on growth; (2) once the effect of inflation uncertainty is accounted for, lagged inflation does not have a direct negative effect on output growth; (3) However as predicted by Friedman and Ball, higher average inflation raises inflation uncertainty, and the overall net effect of average inflation on output growth in Mexico is negative. That is, average inflation is harmful to Mexican growth due to its impact on inflation uncertainty. (4) The Mexican Presidential election cycle significantly raises inflation uncertainty both during the year of the election and the year following the election which has correspondingly negative effects on output growth.     

Are there ENSO signals in the macroeconomy?

Whether ENSO has affected U.S. macroeconomic performance has been a matter of dispute. To address the issue we explore whether there has been any co-cyclicality of ENSO fluctuations and the rates of inflation and economic growth over the 1894-1999 timespan and, failing this, whether aperiodic ENSO shocks have had any impact on these variables. Neither co-cyclicality nor aperiodic shocks are discernible. While ENSO may briefly influence the performance of particular sectors of the economy in particular regions, as documented by the previous literature, such locally-important effects vanish into the noise surrounding macroeconomic trends in an economy as large and complex as that of the U.S.     

中国通货膨胀的动态特征研究

现有测度通胀惯性的常用模型是仅含自身滞后因子的自回归模型,该模型不能有效反映通胀预期和波动性对通胀惯性的影响。本文在自回归模型基础上,构建了一个包含通胀惯性、学习型预期和波动性特征的通胀动态模型。该动态模型从均值和波动项两个方面反映了我国通胀水平的动态变化趋势和特征。针对上述模型不能有效反映通胀状态体制变化的缺点,本文还引入Markov机制转换模型来测度我国通胀水平的状态转移特征。利用分位数回归方法下的自回归模型、本文构建的通胀动态模型以及Markov机制转化模型实证研究了我国通胀的动态特征。分析表明:我国通胀水平具有较强的惯性特征;通胀惯性的形成机理比较复杂,学习型预期只能部分解释通胀惯性;通胀水平的状态转移时间比较长;通胀水平与其波动性有着正向的关系。     

温和通货膨胀下的货币政策选择

2003年以来,我国摆脱了通货紧缩的阴影,进入了一个温和的通货膨胀时期.这一轮温和的通货膨胀主要源于货币信贷的过快增长,而基础货币投放过多主要源于外汇占款的快速增长.实证研究表明,我国通货膨胀率与M0、M1、M2以及贷款增长率之间都存在正相关关系.缓解和释放通货膨胀压力既需要运用数量型货币政策工具,更需要运用价格型货币政策工具.为了缓解通货膨胀压力,中国人民银行应该实行"双升"的货币政策,在调升人民币利率水平的同时调整人民币汇率,既升息又升值,但升息和升值的幅度不宜过大.     

核心通货膨胀:理论模型与经验分析

现有的核心通货膨胀计算方法假设各种商品和服务的价格变化可以表示为核心通货膨胀与异质性相对价格变化之和,然而这种价格变化的分解方式既缺乏理论基础又违背经济直觉。本文将经典的新凯恩斯模型推广到多部门情形,证明了多部门新凯恩斯菲利普斯曲线,提出了各部门商品价格变化的理论分解公式。以这个分解公式为理论基础,本文提出了估计核心通货膨胀的计量经济模型及其两阶段估计方法,给出了根据稳态权重估计核心通货膨胀的简便方法,估计出了我国的核心通货膨胀。有效性检验表明,根据两阶段估计方法和基于稳态权重的估计方法得到的核心通货膨胀都是有效的核心通货膨胀度量。
