Measuring Core Inflation in South Africa

Measures of core inflation convey critical information about an economy. They have a direct effect on the policymaking process, particularly in inflation‐targeting countries, and are utilised in forecasting and modelling exercises. In South Africa, the price indices on which inflation is based have been subject to important structural breaks following changes to the underlying basket of goods and the methodology for constructing price indices. This paper seeks to identify a consistent measure of core inflation for South Africa using trimmed means estimates, measures that exclude changes in food and energy prices, dynamic factor models, and wavelet decompositions. After considering the forecasting ability of these measures, which provide an indication of expected second‐round inflationary effects, traditional in‐sample criteria were used for further comparative purposes. The results suggest that wavelet decompositions provide a useful measure of this critical variable.     

Inflation and relative price variability: Evidence for India

This study decomposes relative price variability into a component due to inflation and a component due to real factors. The empirical results for India suggest that real factors account for 55% and inflation accounts for 45% of the variability in relative price changes. The proportion of inflation induced relative price variability increases with the rise in inflation, implying that inflation has distortionary effects on the structure of relative prices. Further, larger part of variability in the relative price changes seems to have been generated by fluctuations in the relative prices of a few commodities. The sector wise analysis shows that the major share of total relative price variability is contributed by fluctuations in the prices of manufactured products. The more crucial inference that emerges from the empirical analysis is that the inflation rate at which variability of relative price changes is minimum is found to be 4.5%, which is consistent with the official threshold rate often claimed by the Reserve Bank of India.     

What Causes China＇s High Inflation？ A Threshold Structural Vector Autoregression Analysis

China＇s astonishing economic growth implies a necessity to understand its inflation. The present paper employs threshold nonrecursive structural vector autoregression analysis to explore the asymmetric effects of macro-variables on inflation in low and high inflation regimes. The empirical evidence demonstrates, first, that the reactions of inflation to various shocks are inflation-regime-dependent and asymmetric. Second, monetary policy influences China ＂s high inflation and adjusting the domestic interest rate in China may be an effective way to control inflation in a high inflation regime, but not in a low inflation regime. In a high inflation regime, a high inflation rate may cause the macro-policy authorities to increase the domestic interest rate, in an attempt to stabilize high inflation. Third, contrary to expectations, the world oil price is not a strong cost-push factor in a low inflation regime. Oil price increases may increase inflation in a high inflation regime, but there is no such obvious effect in a low inflation regime. Finally, China ＂s nominal effective exchange rate influences inflation in both low and high inflation regimes. A nominal effeetive exchange rate appreciation might be effective in controlling domestic inflation in both regimes.     

我国金融压抑与通货膨胀关系研究——基于MSVAR模型的分析

文章运用MSVAR模型对我国金融压抑程度与通货膨胀的关系进行了研究,发现我国通货膨胀率存在明显的高通胀区域和低通胀区域特征。在高通胀区域,价格高位持续时间较短,波动幅度大,金融压抑对通货膨胀具有显著的负向效应;而在低通胀区域,价格低位持续时间较长,波动幅度小,金融压抑对通胀水平的效应是正向的。两者的非线性特征对货币政策实施和金融自由化策略有着重要的政策含义。     

Inflation Transmission in Greater China

This paper examines inflation dynamics in Greater China. Using an asymmetric error correction model, we investigate how inflation in Hong Kong and Macao are related to inflation in Chinese Mainland. Our results based on data from July 1997 to December 2012 reveal that a long‐term equilibrium relation exists between inflation in Chinese Mainland and inflation in both Hong Kong and Macao, the two Special Administrative Regions of China. The degree of inflation pass‐through is higher for Macao than for Hong Kong. Moreover, we find no evidence of asymmetries in either Hong Kong and Macao's adjustment speeds towards long‐run equilibrium or in the short‐run pass‐through of accelerating or decelerating inflation in the Mainland. Collectively, our results show a close relationship among price dynamics of the three economies and call for a reconsideration of the exchange rate anchor in the Greater China Region.     

Inflation and Economic Growth in China： An Empirical Analysis

Using official provincial data for gross provincial product, consumer price index and other explanatory variables from 1986 to 2006, the present paper investigates the nonlinear effects of inflation on economic growth in China. The main finding of the study is that the inflation threshold effect is highly significant and robust in China. Above the 2.50 percent threshold, every 1‐percentage point increase in the inflation rate impedes economic growth by 0.61 percent; below this threshold, every 1‐percentage point increase in the inflation rate stimulates growth by 0.53 percent. This indicates that high inflation harms economic growth, whereas moderate inflation benefits growth. We suggest that China should maintain a moderate inflation rate for long‐run growth.     

Bank Lending and Inflation in Malaysia: Assessment from Unrestricted Error-Correction Models

The paper estimates inflation models for Malaysia by considering the influence of bank lending. The unrestricted error-correction model (UECM) proposed in Pesaran et al. (2000) was employed as being appropriate for small sample analysis such as the present study which covered annual data from 1973 to 1997. The results of 'bounds' tests confirmed a long-run equilibrium relationship between inflation and its determinants, namely import price, money supply (M3), bank credit and real income. The estimated UECMs revealed that the important factors in the Malaysian inflation process are import price and real-income variables. It was found that concurrent fiscal policies had a major influence on the impact of the depreciation of the naira on inflation. The UECMs appear to perform well and to provide an appropriate framework for forecasting the Malaysian inflation behaviour.     

Will the Sarb always Succeed in Fighting Inflation with Contractionary Policy?

The conventional view is that a monetary policy shock has both supply‐side and demand‐side effects, at least in the short run. Barth and Ramey show that the supply‐side effect of a monetary policy shock may be greater than the demand‐side effect. We argue that it is crucial for monetary authorities to understand whether an increase in expected future inflation is due to supply shocks or demand shocks before applying contractionary policy to forestall inflation. We estimate a standard New Keynesian dynamic stochastic general equilibrium model with the cost channel of monetary policy for the South African economy to show that whether the South African Reserve Bank should apply contractionary policy to fight inflation depends critically on the nature of the disturbance. If an increase in expected future inflation is mainly due to supply shocks, the South African Reserve Bank should not apply contractionary policy to fight inflation, as this would lead to a persistent increase in inflation and a greater loss in output. Our estimation results also show that with a moderate level of cost‐channel effect and nominal rigidities, a New Keynesian dynamic stochastic general equilibrium model with the cost channel of monetary policy is able to mimic the price puzzle produced by an estimated vector autoregressive model.     

Does China have Inflationary Effects on the USA and Japan？

With China＇s share in global trade increasing rapidly, some argued in 2002-2003 that China was exporting deflation to other countries as it was dumping cheap goods in mature markets. Later, others argued that China was causing sharp increases in global prices. This paper uses several econometric techniques to assess the extent of the link between inflation rates between China and the USA and Japan. Only limited empirical evidence at the aggregate level is found for consumer price inflation in China leading to price changes in the USA and Japan. However, there is some evidence that inflation in the USA has an impact on Chinese inflation. The results seem consistent with the Federal Reserve and the Bank of Japan being concerned about inflation and, hence, adjusting policy such that inflation shocks have no significant effect on overall inflation. Recent Chinese price rises are unlikely to have a material effect on the USA or Japan.     

Evidence on the Effects of Money Growth on Inflation with Regime Switching

Since the latter half of 2010, a new round of inflation has gradually been manifesting in China. The debate regarding whether excess money supply is responsible for this inflation has attracted scholars to investigate the effects of money growth on inflation. In this paper, we use correlation analysis to confirm the comovement between growth of monetary aggregates and inflation. We explore the asymmetric effects of monetary policy on inflation using the Markov regime‐switching model. The empirical results show that monetary policy can be more effective in curbing inflation in a high inflation state than in boosting the price level in a low inflation state. However, simply tightening the money supply might not be sufficient to suppress the price level. To this end, the Chinese Government should adopt other policies, such as supply stabilization policies, to help suppress the price level. Our study can help policy‐makers to determine the actual economic state and provides some policy implications for the current inflation.     

基于Markov区制转移模型的财政政策通胀效应检验

价格水平如何决定以及通货膨胀如何治理历来都是经济学家和政府决策部门关心的问题,新近提出的价格水平决定的财政理论强调财政政策变动对价格水平的影响。基于该理论,选取1998-2012年间国债发行和价格水平的季度数据,采取马尔科夫区制转移模型从一个侧面对我国财政政策的通货膨胀效应进行了实证检验,研究发现,积极财政政策对价格水平的影响并不一致,2008年第4季度之前的大部分时间里,积极财政政策所引致的通胀风险并不显著,但2008年之后,积极财政政策则具有显著通胀效应。因此,在治理通货膨胀的政策选择上,改善当前的财政状况,合理地运用财政政策可能是一个更好的选择。     

Do Remittances Induce Inflation? Fresh Evidence from Developing Countries

The goal of this article is to examine the determinants of inflation in both the short run and the long run for 54 developing countries using a panel data set covering the 1995–2004 period. Apart from the commonly used economic determinants of inflation, we model the impact of remittances and institutional variables on inflation. Using the Arellano and Bond panel dynamic estimator and the Arellano and Bover and the Blundell and Bond system generalized method of moments estimator, we find evidence that in developing countries remittances generate inflation. The effect of remittances on inflation is more pronounced in the long run. Moreover, we find that openness, debt, current account deficits, the agricultural sector, and the short‐term U.S. interest rate have a positive effect on inflation. We also find that improvements in democracy reduce inflation.     

Causes of Inflation in China： Inflation Expectations

This paper argues that the main causes of inflation in China since the early 21st century are changes in the public's inflation expectations. The conventional wisdom, the quantity theory of money, may not be adequate to capture the relationship between price changes and money supply growth, as the economic system evolves and people's income and wealth grow. An examination of China's GDP deflator and broad money supply relative to nominal GDP shows that the relationship between the two series is relatively weak. A further examination of China's monthly CPI series over the period 2001–2010 reveals that the autoregressive models are a better fit than the moving average models, which suggests that the role of CPI expectations has been significant and important. Because of the importance of inflation expectations in CPI movement, we believe the Central Bank's monetary policy that targets CPI inflation should emphasize the use of policy instruments that have direct and strong communication links with the public. Quantitative measures would have their own use, but their effectiveness would be unlikely to match that of interest rate measures, especially from a short‐term perspective.     

Exchange-Rate Regimes,Political Parties and the Inflation-Unemployment Tradeoff: Evidence from Greece

We use Greek data during 1960–1994 to test and estimate a model in which wage inflation, price inflation and unemployment depend on the exchange rate regime, the identity of the political party in power and whether an election is expected to take place. We respect the Lucas critique and take into account the statistical properties of the data. The main results are: (i) The exchange rate regime matters for inflation. After the fall of the Bretton Woods regime in 1972, there is a Barro-Gordon type inflation bias due to the inability of all policymakers to precommit to low inflation. (ii) There are no Barro-Gordon type partisan differences in inflation or unemployment.     

The Impact of Inflation Uncertainty on Output Growth and Inflation in Thailand*

We explore the impact of inflation uncertainty on output growth in Thailand, an emerging market economy with moderate inflation. Inflation and output uncertainty are modeled in a bivariate constant conditional correlation generalized autoregressive conditional heteroskedastic (AR(p)‐cccGARCH(1,1)) specification. We include the exchange rate in the mean equations, and use the headline and core inflation rates and industrial production to generate inflation and output uncertainty series. These series are then used in Granger causality tests to make inferences about the effect of monetary policy‐induced inflation uncertainty. Causality tests show a positive relation from inflation to inflation uncertainty. Additionally, increased inflation uncertainty decreases output. These results are consistent with real costs associated with moderate inflation. Finally, we find no evidence that monetary policy reduced these costs.     

Multiple Structural Breaks and Inflation Persistence: Evidence from China

The degree of inflation persistence fluctuates more in developing countries than in industrialized countries. This is because there are more economic reforms in developing countries than in industrialized countries. Hence, it is important to study the inflation persistence in developing countries. The present paper investigates the pattern of inflation persistence in China, a developing and transitional economy. Specifically, the paper studies statistically the number of structural breaks in China's inflation persistence based on the monthly retail price index (MRPI) and the quarterly retail price index (QRPI) inflation series from 1983 to 2011. The findings show that there are five and three structural breaks in the MRPI and QRPI inflation persistence, respectively. The present paper also exposes a high degree of persistence over the whole sample period and a slight decline in the level of the persistence since 1994. Furthermore, the persistence of two inflation series does not change monotonously but with obvious cyclical patterns. Using these derived estimated structural breakpoints, likely causes of the breakpoints in inflation persistence are investigated. Finally, theoretical and practical implications are discussed.     

近期我国通货膨胀的原因及应对策略分析

通常情况下，通货通胀由经济过热引起，治理措施重点放在紧缩信贷、减缓经济增速方面。而我国货币发行量已经有所节制，经济增长幅度也在缩小，通胀却在攀升，2008年5月12日，国家统计局发表4月GPI指数上涨8．5％，比3月的83％，环比增长0．1％。此次我国发生的CPI指数上升与以往通胀不同，显然我们还有疏漏。原因是多方面的，本文主要从以下三个方面分析：一是涨价中有合理因素，如农产品涨价；二是进口型通胀；三是与世界经济接轨导致原来的价格体系转化，新的与世界密切联系的价格体系正在形成之中产生的价格波动、拉升，连带滋生出泡沫。在分析原因的基础上，给出一些应对性策略。     

汇率传导、人民币升值与通货膨胀的关联度

经济开放度在汇率传导过程中起着重要作用,考虑经济开放度后,汇率调整对国内通货膨胀的影响显著增强。研究表明,进口依存度与汇率传导效应正相关,金融开放度与汇率传导效应负相关。通过构建模型,进行实证分析,结果显示,我国的原材料购进价格指数、生产者价格指数和居民消费价格指数与进口依存度、金融开放度和人民币汇率波动关系密切。在现阶段的宏观经济形势下,人民币合理适度的升值有助于缓解国内的通货膨胀压力,促进我国经济内外部均衡发展。     

Inflation Targeting and Relative Price Variability: What Difference Does Inflation Targeting Make?

This article studies the effects of inflation targeting (IT) on relative price variability (RPV) using a data set of twenty countries comprising both targeters and nontargeters. We find that a decline in mean inflation after IT adoption is not necessarily associated with a similar fall in RPV and that what matters most for the structural changes in RPV is the initial inflation regime prior to the adoption of IT rather than IT adoption itself. IT adoption impacts the shape of the underlying relationship between inflation and RPV in countries with initially high inflation rates, moving it from monotonic to the U‐shaped profile observed consistently for countries with low‐inflation regimes. The minimum point of this U‐shaped curve is indicative of the public's expectations of inflation and is very close to the announced target for inflation in most of the countries we study.     

通胀率动态与通胀惯性度量

本文从通胀惯性的理论模型出发,构建无限状态Markov区制转移的计量模型,实现对通胀惯性的有效度量。对美国通胀惯性的实证分析,证实货币政策工具的频繁使用会付出通胀惯性的代价,暴露出其单一目标货币政策框架的缺陷。我国央行的调控也已经对市场利率形成了显著的传导作用,谨慎地使用货币政策工具,使我国的通胀惯性在被货币政策短暂影响后,得以有效恢复。这表明坚持实行多目标、多手段与宏观审慎政策相结合的调控模式,对维护经济环境稳定与长期发展的重要性。十国通胀惯性的度量结果与对比分析,进一步佐证了本文观点。
