Is Inflation Always and Everywhere a Monetary Phenomenon?*

Using a sample of about 160 countries over the last 30 years, we test for the quantity theory relationship between money and inflation. When analysing the full sample of countries, we find a strong positive relation between long‐run inflation and the money growth rate. The relation is not proportional, however. The strong link between inflation and money growth is almost wholly due to the presence of high‐(or hyper‐) inflation countries in the sample. The relationship between inflation and money growth for low‐inflation countries (on average less than 10% per annum over the last 30 years) is weak.     

Fiscal and Monetary Policies in a Transactions‐Based Endogenous Growth Model with Imperfect Competition

This paper's model is capable of explaining the empirical evidence on the mixed growth‐rate effects of fiscal and monetary policies and a nonlinear inflation–growth relation. When monopoly power in the product market is strong/weak, an increase in the money growth rate or the income tax rate promotes/reduces the output growth rate through lowering/raising the equilibrium gross markup and increasing/reducing the net rate of return on capital. The fact that money can generate a positive growth rate effect allows for the appearance of a nonlinear inflation–growth relation. Such a nonlinear relation cannot be caused by changes in the income tax rate.     

Is there Causal Relationship between Money Supply Growth and Inflation in China? Evidence from Quantity Theory of Money

This study examines the causal relationship between Chinese money supply growth and inflation, using the bootstrap Granger full‐sample causality test and sub‐sample rolling‐window estimation test to determine whether such a relationship in China supports the quantity theory of money. The result indicates that there is a unidirectional relationship from inflation to money supply growth. However, considering structural changes in two series, we find that short‐run relationships using full‐sample data are unstable, which suggests that full‐sample causality tests cannot be relied upon. Then, we use a time‐varying rolling‐window approach to revisit the dynamic causal relationship, and the results show that money supply growth has both positive and negative impacts on inflation in several sub‐periods, and in turn, inflation has the same effects on money supply growth for China. These findings are basically consistent with the modern quantity theory of money from the perspective of money supply and price level. When money supply growth does not outweigh output growth, inflation should not be curbed only by decreasing money supply. It notes that a stable money supply growth is critical to price level stability and economic development in China.     

THE EVOLUTION OF INFLATION AND UNEMPLOYMENT: EXPLAINING THE ROARING NINETIES

This paper analyses the relation between US inflation and unemployment from the perspective of ‘frictional growth,’ a phenomenon arising from the interplay between growth and frictions. In particular, we focus on the interaction between money growth and nominal frictions. In this context we show that monetary policy has not only persistent, but permanent real effects, giving rise to a long‐run inflation‐unemployment tradeoff. We evaluate this tradeoff empirically and assess the impact of productivity, money growth, budget deficit, and trade deficit on the US unemployment and inflation trajectories during the nineties.     

我国通货膨胀与货币供给和经济增长的关系研究

基于协整检验和VAR模型选取1984～2010年的年度数据研究了通货膨胀与货币供给和经济增长之间的关系,研究表明:货币供给和经济增长都会导致通货膨胀,但通货膨胀不会引发货币超发,且一定的通货膨胀对经济增长具有正向刺激作用;货币供应量扩张对通货膨胀有促进作用,但影响程度逐步减弱,经济增长也会促使物价水平的上涨,但影响程度明显小于货币供给水平的影响;经济增长对物价水平的影响小于货币供应量对物价水平的影响,即货币供应量诱发通货膨胀,抑制通货膨胀的最好途径是解决货币供给问题;经济系统中存在"通货膨胀螺旋"效应。     

Response to Seitz and Tödter, 'How the P* Model Rationalizes Monetary Targeting: A Comment on Svensson'

Seitz and TÎdter argue, counter to Svensson, that the P * model provides a rationale for money-growth targeting. In particular, they argue that 'money growth targeting is a special form of inflation forecast targeting based on a "limited" information set. In contrast to "full information" inflation forecast targeting, money growth targeting is likely to be more robust under changing conditions of the real world'.
However, money-growth targeting is better described as a special case of inflation targeting, namely when money growth is considered to be the only predictor of future inflation. But there is overwhelming empirical evidence that there are not only other, but also better, predictors of future inflation than money growth, which makes inflation-forecast targeting superior to money-growth targeting. Inflation-forecast targeting is indeed more robust (in the sense of using available information and allowing judgemental adjustments in a flexible way) than monetary targeting.
In particular, in the P * model, the real money gap is a better predictor of future inflation than money growth, as demonstrated theoretically by Svensson and empirically by Gerlach and Svensson (the empirical finding is also confirmed by Trecroci and Vega). Therefore, inflation-forecast targeting is superior also within the P * model. Under `changing conditions of the real world', for instance after the formation of a monetary union, money growth is likely to be particularly unreliable as a predictor of future inflation, making monetary targeting especially unsuitable and non-robust.     

How justified is abandoning money in the conduct of monetary policy in Australia on the grounds of instability in the money‐demand function?

The role of money in the design and conduct of monetary policy has reemerged as an important issue in both advanced and developing economies, especially since the 2007 global financial crisis. A growing body of recent literature suggests that the causal relationship between money supply growth and inflation remains intact across countries and over time and that this relation is not conditional on the stability of the money‐demand function or whether money is endogenous or exogenous. Moreover, critical for a rule‐based monetary policy is the presence of a long‐run stable money‐demand function, rather than a short‐run money‐demand model that may exhibit instability for many reasons, including problems with estimating a money‐demand model with high‐frequency data. Provided that a stable money‐demand function exists, it could be useful to establish long‐run equilibrium relations among money, output, prices, and exchange rates, as the classical monetary theory suggests. Within this analytical framework, this paper addresses the question of whether money has any role in the conduct of monetary policy in Australia. The conventional wisdom is that the money‐demand function in Australia has been unstable since the mid‐1980s due to financial deregulation and reforms; this led to a change in the strategy of monetary policy for price stability in the form of inflation targeting that ignores money insofar as inflation and its control are concerned. This paper reports empirical findings for Australia, obtained from a longer quarterly data series over the period 1960Q1–2015Q1, which suggest that instability in the narrow‐money‐demand function in Australia was primarily due to the exclusion of variables which have become important in the deregulated environment since the 1980s. These findings are confirmed by an expanded form of the narrow‐money‐demand function that was found stable over the past two decades, although it experienced multiple structural breaks over the study period. The paper draws the conclusion that abandoning the monetary aggregate as an instrument of monetary policy in Australia, under a rule‐based monetary policy such as inflation targeting, cannot be justified by instability in the money‐demand function or even by lack of a causal link between money supply growth and inflation.     

Granger causality of the inflation–growth mirror in accession countries*

The paper presents a model in which the exogenous money supply causes changes in the inflation rate and the output growth rate. While inflation and growth rate changes occur simultaneously, the inflation acts as a tax on the return to human capital and in this sense induces the growth rate decrease. Shifts in the model's credit sector productivity cause shifts in the income velocity of money that can break the otherwise stable relationship between money, inflation, and output growth. Applied to two accession countries, Hungary and Poland, a VAR system is estimated for each that incorporates endogenously determined multiple structural breaks. Results indicate Granger causality positively from money to inflation and negatively from inflation to growth for both Hungary and Poland, as suggested by the model, although there is some feedback to money for Poland. Three structural breaks are found for each country that are linked to changes in velocity trends, and to the breaks found in the other country.     

货币供给、通货膨胀、经济增长之间关系的实证研究——基于2006～2010年数据的分析

利用我国2006年12月～2010年12的月度数据,在VAR模型的基础上,对我国货币供应、通货膨胀、经济增长之间的关系进行实证分析。研究发现,短期内通货膨胀和经济增长对货币供应量的效应相反;货币供应并不影响通货膨胀和经济增长;经济增长与通货膨胀无关,通货膨胀对经济增长具有正面效应。长期来看,通货膨胀和货币供应量之间正相关;经济增长对货币供应具有负效应,货币供给量的增加促进经济增长,证实我国存在托宾效应;经济增长和通货膨胀之间作用相反,通货膨胀损害经济增长的弗里德曼假说在我国适用。同时得出我国货币供给具有非中性和内生性特点的结论。     

中国货币供应、通货膨胀及经济增长关系实证研究

采用协整与方差分解的方法时中国货币供应、通货膨胀与经济增长的关系进行实证研究发现，通货膨胀与经济增长在短期和长期中作用关系相反，但都具有回归自然水平趋势，货币供应时通货膨胀和经济增长的影响具有滞后效应，长期内货币非中性。而通货膨胀和经济增长并不影响货币供应。一方面。应当采取措施降低货币供应增长率：另一方面，偏紧货币政策的滞后效应可能导致经济紧缩应当采取措施降低货币供应增长率，因此应谨慎调控宏观经济政策，以避免金融风险。     

货币增长不确定性与通货膨胀不确定性——“波动溢出”假说与实证检验

文章基于通货膨胀——通货膨胀不确定性关系的理论研究,提出货币增长不确定性向通货膨胀不确定性波动溢出的计量检验假说,并利用中国数据,运用多元GARCH模型进行实证检验。结果发现,存在货币增长不确定性显著向通货膨胀不确定性波动溢出的效应。这意味着,货币增长不确定性具有提供有关预测通货膨胀不确定性信息的能力。同时也表明,货币增长不确定性是通货膨胀不确定性的重要解释变量,其重要性不应被忽视。实证结论的政策含义是:减少货币增长不确定性是降低通货膨胀不确定性的重要途径,我国20世纪90年代中后期稳健的货币政策所带来的通货膨胀不确定性显著降低的现实支持了这个观点。     

Deficit spending,money, and inflation: Some international empirical evidence

An attempt is made, in this study, to examine the monetarist propositions regarding the effects of budget deficits on money growth and inflation for ten industrialized countries. To this end, a two-equation econometric model consisting of the money supply growth and inflation equations has been specified and estimated. Based on the results, it is concluded that, in general, the government budget deficit is not a determinant of money supply growth or of inflation (directly or indirectly). The U.S. is an exception with some statistical evidence of direct and indirect effects of the budget deficit on inflation.     

Does money have a role in the inflation process? Evidence from Australia

Inflation, defined as a sustained increase in the price level, is considered a monetary phenomenon, as it can be explained within the framework of money‐demand and money‐supply relationships. In the extant literature, money growth is shown to remain causally related to inflation across countries and over time, irrespective of the exchange rate regime and stability of the money‐demand function. Nevertheless, emerging literature suggests a diminishing role of money in the conduct of monetary policy for price stability, especially under inflation targeting. Monetary policy in Australia under inflation targeting since 1993 is an example of policy that denies a relationship between money growth and inflation. The proposition that money does not matter insofar as inflation is concerned seems odd in both theory and the best‐practice monetary policy for price stability. This paper uses annual data for the period 1970–2017 and quarterly data for the period 1970Q1–2015Q1. It deploys both the Johansen cointegration approach and the autoregressive distributed lag (ARDL) cointegration approach to investigate for Australia whether money, real output, prices and the exchange rate (non‐stationary variables) maintain the long‐run price‐level relationship that the classical monetary theory suggests in the presence of such stationary variables as the domestic and foreign interest rates. As expected, the empirical findings for Australia are consistent with the classical long‐run price‐level relationship between money, real output, prices and the exchange rate. The error‐correction model of inflation confirms the presence of a cointegral relationship among these variables; it also provides strong evidence of a short‐run causal relationship between money supply growth and inflation. On the basis of a priori theoretical predictions and empirical findings, the paper draws the conclusion that the monetary aggregate and its growth rate matter insofar as inflation is concerned, irrespective of the strategy of monetary policy for price stability.     

A money demand system for German M3

A small macroeconomic model is constructed starting from a German money demand relation for M3 based on quarterly, seasonally unadjusted data for the period from 1976 to 1996. In contrast to previous studies we build a vector error correction model for M3, GNP, an inflation rate and an interest rate spread variable to represent opportunity costs of holding money. Furthermore, import price inflation is added as an exogenous variable. The model is used to analyze the relation between money growth and inflation by means of an impulse response analysis.We thank Gerd Hansen for soliciting two anonymous referee reports on an earlier version of this article and thereby helping in the editorial process for this volume.

货币政策对物价稳定和经济增长的效应——中国与巴基斯坦的比较研究

本文采用自回归分布滞后模型对中国和巴基斯坦两国货币政策、通货膨胀与经济增长之间的长期关系进行了比较研究,由此得出如下几点结论:第一,两国的经验数据都印证了经济学家们普遍接受的通货膨胀是一种货币现象的推论;第二,货币非中性假说在两国的经验数据中均无法被拒绝;第三,在中国存在货币数量论所描述的货币供给与通货膨胀同步增长的预测关系,而这种关系在巴基斯坦却不存在;第四,两国若想实现较高的经济增长都必须在长期内降低通货膨胀率。     

中国货币供给与通货膨胀的关联性研究

关于货币供给与通货膨胀的关联性,学者们还没有形成一致的看法.理论上,货币供给与通货膨胀具有一定的关联性.通货膨胀有需求拉动型和成本推动型,在通货膨胀的原因中有“货币因素”,也有“非货币因素”.实证检验表明:中国货币供应量与物价指数不存在长期的稳定均衡关系,但货币供应量是物价指数的格兰杰原因,反之则不然.事实上,中国通货膨胀或通货膨胀压力一方面是与货币供给有关,另一方面还与结构性因素有关.因此,要实现中国经济的低通胀运行:一是实行总量均衡和结构合理的货币供给模式;二是采取更有效的货币政策;三是推进经济结构调整,实现国际收支平衡;四是深化金融体系改革,增强中央银行货币控制能力;五是进行汇率机制改革;六是通过财政政策调整供需结构.     

基于VECM的治理通胀与经济发展协调性研究

笔者基于VECM模型对利率、汇率、货币供给、经济增长与通货膨胀之间的关系进行研究,发现它们之间存在协整关系,利率、汇率、货币供给增长率与通货膨胀具有双向影响关系,而经济增长率单向影响通货膨胀,利率不是经济增长率的格兰杰因,汇率、货币供应量增长率与经济增长率之间都不存在格兰杰因果关系,五个变量互相之间的作用都有较长滞后效应。通过深化改革、完善市场机制、转变经济增长方式可以保增长防通胀。     

我国M1货币政策中介目标的 一个合理选择

本文定义了货币M1的一个新增长率,以其值作为与实际经济增长率相适应的中介目标值;定义了货币M1的一个超额增长率,以其负值作为与通货膨胀率相适应的中介目标值;在此基础上,重新确定M1货币增长率的值作为中介目标值。实证表明在中国这样确定的货币政策中介目标值与经济增长和通货膨胀最终目标一致。     

后金融危机的货币供给过剩及其效应

本文针对我国货币政策的操作特征,使用阈值协整方法扩展现有的货币需求模型,度量后金融危机时期的货币供给过剩及其对通胀与经济增长的非线性调节效应,并进而设定广义脉冲响应函数揭示货币供给过剩对通胀与经济增长的冲击效应。主要结论为:2009年第三季度以后,我国货币供给过剩且过剩幅度快速增加,其中名义M1过剩12.56%,名义M2过剩11.31%。2009Q3—2010Q3我国处于货币供给过剩机制下,在该机制下,央行谨慎地实施从紧货币政策,从紧货币政策对通胀和经济增长的调节效应相对较强。货币供给过剩对通胀和经济增长的冲击在前2年为正值,在随后近3年为负值。这说明我国现阶段适度宽松货币政策的退出必须谨慎,退出速度不宜过快。     

On the monetary-macro dynamics of Colombia and Mexico

This paper investigates the dynamic interrelationship among money growth, inflation, and output growth for Colombia and Mexico on the basis of implementation of a vector autoregression methodology. The evidence for Colombia generally shows autonomous output growth and money growth behavior, and an important role for money shocks in accounting for variations in inflations. A different pattern of results emerged for Mexico: there are strong two-way feedbacks among money growth and inflation, and a less autonomous output growth behavior than in Colombia.
