中国通胀水平与通胀不确定性:马尔柯夫域变分析

本文使用中国1985年以来月度数据,基于马尔柯夫域变模型考察了通胀水平及其与不确定性的关系。我们将通胀的不确定性分解为两类成分:未来通胀冲击的不确定性和未来通胀均值域变的不确定性。研究结果表明,高的通胀水平伴随着这两类不确定性成分的同时增大,这意味着通胀成本很大程度上和不确定性的成本联系在一起,稳定价格和维持低通胀环境可能成为央行减少不确定性的重要手段。本文结果还表明,域变模型相对线性自回归模型以及ARCH模型更好地刻画了中国通胀率过程的特点。以往应用中忽略了这种域变特点可能导致通胀预测值相对于真实值的系统性偏差,或者通胀不确定性的错误估计。

通货膨胀与物价目标

针对近年来全国各界对通货膨胀的关切和“物价总水平基本稳定”的提法,本文认为有些认识和思路值得反复理清,包括：如何界定通货膨胀及如何看待通货膨胀;通货膨胀与经济增长如何匹配;中国可能期望的,也是难以避免的通货膨胀率是什么水平。文章提出治理通货膨胀要服从核心任务,应建立现实的通货膨胀观念,并在对保持物价总水平基本稳定的提法进行多视角诠释的基础上,给出了控制物价的几点政策建议。     

中国的通货膨胀惯性与通货膨胀不确定性——基于有限理性NKPC模型的分析

本文拓展有限理性菲利普斯曲线模型并结合中国参数进行校准,然后利用校准模型研究中国通货膨胀惯性特征及其与通货膨胀不确定性之间的关系。结果显示,有限理性菲利普斯曲线模型能很好地模拟出与中国实际通货膨胀惯性类似的特征。进一步研究还发现,研究样本期间,中国通货膨胀惯性总体上呈现先上升而逐渐下降的驼峰型特征,而且与通货膨胀预期不确定性存在正向相关关系。这些发现意味着,我国中央银行货币政策滞后效应正在缩短,而为了进一步降低通胀惯性并提高货币政策有效性,引导通货膨胀预期保持稳定是一大途径。     

通货膨胀与社会福利损失

通货膨胀到底对经济有多大的影响?这是经济学家和各级政府所关心的问题.本文按照Lucas(2000)的方法,在Gong和Zou(2001)给出的带有人们对社会地位的追求和消费品及投资品的Cash-in-Advance约束的模型的基础上分析了通货膨胀对社会福利的影响,给出了通货膨胀的福利损失的估计.     

试析人民币对外升值与对内贬值并存

2002年以来,人民币出现了对外升值和对内贬值并存的现象。在国际美元贬值和国内流动性过剩的背景下,这一货币现象得到了强化。当然,这一货币现象是实际经济运行的反映。主要线索是,中国的出口导向型经济强势增长,国际收支持续顺差带来巨额外汇储备,并进而推动国内货币供应量的扩张。当汇率和资本流动都受到管制时,压抑的对外升值趋势会成为对内贬值的直接原因。而对内贬值的概念已不是传统意义上的CPI上涨,而是包括资产价格膨胀在内的广义通货膨胀。这对于宏观经济平衡和货币政策制定者来说,都是一场新的挑战。     

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。     

A political economy perspective on persistent inequality,inflation, and redistribution

In this paper we examine the dynamics of the link between inequality and inflation from a political economy perspective. We consider a simple dynamic general equilibrium model in which agents vote over the desired inflation rate in each period, and inequality is persistent. Inflation in our model is a mechanism of redistribution, and we find that the link between inequality and inflation within any period or over time depends on institutional and preference related parameters. Furthermore, we find that differences in the initial distributions of wealth can yield a diverse set of patterns for the evolution of the inflation and inequality link. Relative to existing literature, our model leads to more precise predictions about the inflation–inequality correlation. To that end, results in the extant empirical literature on the inflation and inequality link need to be interpreted with caution.     

中国通胀惯性特征与货币政策启示

通胀惯性与货币政策效果紧密相关。本文应用具有统计无偏性的"Grid Bootstrap"估计法和未知断点结构突变检验法,研究了1980—2007年中国通货膨胀的惯性特征。本文发现,在低通胀环境下通货膨胀仍然呈现相当高的惯性特征,这暗示着我国货币政策的滞后效应依然非常明显,通货膨胀对政策变化的反应速度缓慢。计量结果说明,中央银行至少应该在出现通胀压力前一年采取措施,来应对高通胀惯性环境下的政策滞后效应。因此,新时期货币当局不仅需要保持对通胀抬头趋势的适度警觉,而且应该关注高通胀惯性对政策效果的影响。     

Towards an information economy : The case of Singapore

Recent empirical studies have documented the emergence of information-based economies in developed countries within Europe, the U.S.A., Japan, and Australia. Casual observations suggest that the newly industrializing country of Singapore is proceeding towards a similar trend. The primary purpose of this paper is to account for the share of Singapore's national product which originates from informational activities. In particular, we define and estimate the size of Singapore's information sector within an input-output framework. Our results indicated that a sizable portion of Singapore's economy is information-based. In view of the significant penetration of informational activities in economic production, advances in communication technology and concomitant improvements in information-handling capabilities are bound to affect factor productivities and incomes with consequences for a country's pattern of employment and production structure. It is anticipated that an economics of communication becomes necessary for an awareness of communication technology as a choice variable in economic planning. We conclude our discussion with an assessment of the admissability of an information sector concept in economic analysis and the usefulness of empirical studies based on such a concept.     

Inflation and the fiscal limit

We use a rational expectations framework to assess the implications of rising debt in an environment with a “fiscal limit”. The fiscal limit is defined as the point where the government no longer has the ability to finance higher debt levels by increasing taxes, so either an adjustment to fiscal spending or monetary policy must occur to stabilize debt. We give households a joint probability distribution over the various policy adjustments that may occur, as well as over the timing of when the fiscal limit is hit. One policy option that stabilizes debt is a passive monetary policy, which generates a burst of inflation that devalues the existing nominal debt stock. The probability of this outcome places upward pressure on inflation expectations and poses a substantial challenge to a central bank pursuing an inflation target. The distribution of outcomes for the path of future inflation has a fat right tail, revealing that only a small set of outcomes imply dire inflationary scenarios. Avoiding these scenarios, however, requires the fiscal authority to renege on some share of future promised transfers.     

An augmented P-star model of Indian inflation

ABSTRACT

An augmented P-Star model is estimated and tested to identify the drivers of inflation in India. The model includes monetary and non-monetary factors, demand-pull and cost-push factors, and domestic as well as foreign factors. The results show that inflation in India is driven by a combination of monetary factors and non-monetary factors, some of which affect inflation on the supply side while others operate on the demand side. It turns out, however, that inflation in India is determined more by domestic rather than foreign factors.

中国通货膨胀的福利成本研究

通货膨胀一直以来都是衡量一国宏观经济运行是否稳定和健康的重要指标。本文对国内外关于通货膨胀福利成本的研究发展进行了较为完整的综述,并在此基础之上运用消费者剩余方法和新古典宏观经济学一般均衡模型对中国通货膨胀的福利成本进行了计算和比较。实证结果说明,在中国高通货膨胀会带来较高的福利损失,因此将通胀率保持在较低的水平对提高中国的经济福利水平是有利的。     

Inflation and stabilization in Argentina

This paper reports the results of simulation experiments which were conducted by using a CGE model of Argentina. The results suggest that: the economy could not have been stabilized by using the preannounced devaluation rate during 1978-81; economic performance could have improved in 1985-89 under a modified Austral plan but, with the altered structure, there would still be a severe currency appreciation; and the Convertibility Law based programme is very successful in arresting inflation and eliminating a budget deficit, though it is not free from side effects such as money supply shortages and high interest rates.     

Time Series Analysis of Inflation Targeting in Selected Countries

Abstract

We analyze a set of countries which adopted inflation targeting (IT) as a policy tool. We model the pre‐IT period with ARMA and GARCH methods, and conduct the one‐step ahead forecasting for the remainder of the times series data. The actual and forecasted inflation levels are compared for each country. We find that even though the actual inflation levels are lower than the forecasted ones, there is no statistical evidence to suggest that the adoption of IT causes a structural break in the inflation levels of the countries which adopt IT.     

外部冲击与中国的通货膨胀

本文在充分考察全球流动性的转化、国际大宗商品价格的传导、人民币汇率升值的紧缩效应、国际利率的影响以及价格扭曲效应为外部冲击所放大等典型化事实基础上,应用扩展的菲利普斯曲线方程和VAR模型对外部冲击影响国内通胀进行了经验研究。计量结果表明:短期内,国际食品价格是导致国内物价上涨的主要因素;国际原油价格对国内物价的影响在中长期逐步上升;人民币升值抑通胀的效果要经过一段时间才能体现出来;国际利率变化对国内物价有影响;全球流动性的转化因央行的有效对冲对物价的直接影响并不明显。综合而言,外部冲击只是导致通胀的因素之一,而GDP增长率仍是影响物价的最主要因素。因此,防止经济增长过快,调整要素价格抑制投资需求膨胀,以及提高汇率机制弹性以增强货币政策独立性并使之成为应对外部冲击的第一道防线,将是治理中国通胀的根本途径。     

Monetary Constitution, Political-Economic Regime, and Long-Term Inflation

Empiricaldata about inflation in different countries for about two hundredyears since 1800 demonstrate the importance of monetary regimesor constitutions as to the long-term inflationary bias of therespective currencies. Regimes binding the hands of governmentare less inflation-prone than others. This empirical fact isa consequence of political competition inducing governments tofavor inflationary monetary policies.     

Inflation,growth, and distribution: The Brazilian economy after the post war

Abstract

Following Marglin and Bhaduri (1990 Marglin, S.A., and Bhaduri, A. “Profit Squeeze and Keynesian Theory.” In S.A. Marglin and J. Schor (eds.), The Golden Age of Capitalism. Reinterpreting the Postwar Experience. Oxford: Clarendon, 1990. [Google Scholar]), the purpose of this paper is to investigate empirically the interaction between income distribution and growth of aggregate demand during the 1951–89 period in Brazil. Applying Hein and Vogel’s (2008) methodology we conclude that the Brazilian economy showed a profit-led demand regime. In a context of high inflation, high concentration of markets, and wage control, retained profits were the main source to finance new capital. In this sense, we found a large sensitivity of investment relative to the wage share, a result that is compatible with a consumption pattern based on high income, which supported the growth trend with low wages observed during the period.     

通货膨胀不确定性及其对宏观经济的影响

利用马尔科夫范式转换模型分析了1985年1月到2009年7月我国通货膨胀的状态转换特征,并考察了与之伴随的不确定性及其对我国主要宏观经济变量的影响,发现通货膨胀不确定性仅对消费波动有显著影响,对投资和净出口的影响不显著,且方差不确定性和均值不确定性分别导致了消费波动增大与减小.通货膨胀不确定性凸显了宏观调控的重要性,积极、有效、透明的政策能够减少消费所面临的不确定性,保证居民消费的稳定和可持续增长,将有助于扩大内需,促进我国经济增长.
