Pass-through Effects of Global Commodity Prices on China＇s Inflation： An Empirical Investigation

The present paper uses a two-step approach to estimate the pass-through effects of changes in international commodity prices and the RMB exchange rate on domestic consumer price inflation in China. We first estimate the pass-through effects of international commodity prices on producer prices and then estimate the pass-through effects of producer price inflation on consumer price inflation. We find that a l O-percent increase in international commodity prices would lead to China＇ s producer prices increasing by 1.2 percent 3 months later, which in turn would increase China＇ s domestic inflation by 0.24 percent over the same period. However, a 10-percent appreciation of the RMB exchange rate against the US dollar would help to reduce increases in producer prices by 4.4 percent over the following 3 months, which in turn would lead to a 0. 89-percent decline in consumer price inflation over the same period. Our findings suggest that appreciation of the RMB in an environment of rising global commodity prices and a weak US dollar could be an effective instrument to help contain inflation in China.     

Inflation in developing Asia: pass‐through from global food and oil price shocks

The world economy experienced a sharp spike in food and oil prices during 2007 and 2008. In light of developing Asia's dependence on imported oil and food, we can expect higher global food and oil prices to result in higher domestic consumer prices in the region. However, the actual impact of the global commodity shocks on consumer price inflation in developing Asia depends on a number of other factors, including government policy measures. The objective of this paper is to examine empirically the extent of the pass‐through of global food and oil prices to domestic consumer prices in nine countries in the region. The main empirical result is that the magnitude of the pass‐through has been limited. Government policy measures, for example, subsidies and price controls, played a role in reducing or delaying the pass‐through of oil and food price increases to domestic prices.     

Exchange Rate Pass-through in China

During the second half of 2007 and early part of 2008 when there were intense inflationary pressures in China, RMB appreciation was advocated as a means of helping to curb inflation. The effectiveness of appreciation in controlling inflation depends on the impact of exchange rate movements on import and domestic prices. Our analysis finds fairly large and speedy exchange rate pass-through （ERPT） to import prices： 50 and 60percent for the short run and long run, respectively. However, the degree of ERPT decreases along the price chain from upstream to downstream prices. ERPT for consumer prices, the most downstream prices, is much milder and has substantial lags. A 10-percent rise in the nominal effective exchange rate will dampen consumer prices by 1.1 percent within a year, with very little pass-through in the first half year, and by 2.0percent over the long run. These findings, particularly the ERPT to consumer prices, suggest that RMB appreciation can help to reduce inflationary pressures over the longer term. However, it is unlikely to provide rapid relief to the current round of high inflation because of the long lags in ERPZ. The RMB needs to strengthen in effective terms to exert the desired dampening impact on prices.     

Global food prices and monetary policy in an emerging market economy: The case of India

This paper investigates a perception in the political debates as to what extent poor countries are affected by price movements in the global commodity markets. To test this perception, we use the case of India to establish in a standard SVAR model that global food prices influence aggregate prices and food prices in India. To further analyze these empirical results, we specify a small open economy New-Keynesian model including oil and food prices and estimate it using observed data over the period 1996Q2 to 2013Q2 by applying Bayesian estimation techniques. The results suggest that a big part of the variation in inflation in India is due to cost-push shocks and, mainly during the years 2008 and 2010, also to global food price shocks, after having controlled for exogenous rainfall shocks. We conclude that the inflationary supply shocks (cost-push, oil price, domestic food price and global food price shocks) are important contributors to inflation in India. Since the monetary authority responds to these supply shocks with a higher interest rate which tends to slow growth, this raises concerns about how such output losses can be prevented by reducing exposure to commodity price shocks.     

Core Import Price Inflation in the United States

The cross-section distribution of U.S. import prices exhibits some of the fat-tailed characteristics that are well documented for the cross-section distribution of U.S. consumer prices. This suggests that limited-influence estimators of core import price inflation might outperform headline or traditional measures of core import price inflation. We examine whether limited influence estimators of core import price inflation help forecast overall import price inflation. They do not. However, limited influence estimators of core import price inflation do seem to have some predictive power for headline consumer price inflation in the medium term.     

Price‐Setting Behaviour in Lesotho: Stylised Facts from Consumer Retail Prices

This paper documents some of the main features of price‐setting behaviour by retail outlets in Lesotho over the period March 2002 to December 2009. These features include the frequency, size, duration and synchronisation of price changes. In addition, the paper compares price‐setting behaviour in Lesotho and South Africa using a comparable set of products. The findings reveal considerable heterogeneity in price‐setting behaviour across products, outlets, locations and time. Variations in inflation are strongly correlated with the average size of price changes, but rising inflation raises the frequency of price increases and reduces the frequency of price decreases. Price decreases constitute an important determinant of inflation movements. Surprisingly, the frequency and size of price changes in Lesotho differ substantially from those in South Africa, despite the presence of common retail chains and their joint membership in a customs union and common monetary area. These findings open up opportunities for further research into the sources of heterogeneity across products and Lesotho and South Africa in the setting of prices.     

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.

本文考察了2005年7月至2008年2月期间人民币汇率变动对我国物价水平的影响。研究表明,人民币名义有效汇率变动对进口价格的传递是不完全的,当人民币名义有效汇率每变动一个百分点时,进口价格指数仅变化0.22个百分点;人民币名义有效汇率与国内物价水平存在负相关性,这与以往的研究结论恰好相反,对此,本文从人民币升值预期和人民币均衡汇率两个视角作了解释;全球商品价格指数并非影响我国国内物价水平的最重要因素,我国经济体具备较强的抵御外来冲击的能力。     

Exchange Rate Pass-through in a Small Open Economy: the Importance of the Distribution Sector

The degree of exchange rate pass-through to domestic goods prices has important implications for monetary policy in small open economies with floating exchange rates. Evidence indicates that pass-through is faster to import prices than to consumer prices. Price setting behaviour in the distribution sector is suggested as one important explanation. If distribution costs and trade margins are important price components of imported consumer goods, adjustment of import prices and consumer prices to exchange rate movements may differ. We present evidence on these issues for Norway by estimating a cointegrated VAR model for the pricing behaviour in the distribution sector, paying particular attention to exchange rate channels likely to operate through trade margins. Embedding this model into a large scale macroeconometric model of the Norwegian economy, which inter alia includes the pricing-to-market hypothesis and price-wage and wage-wage spirals between industries, we find exchange rate pass-through to be quite rapid to import prices and fairly slow to consumer prices. We show the importance of the pricing behaviour in the distribution sector in that trade margins act as cushions to exchange rate fluctuations, thereby delaying pass-through significantly to consumer prices. A forecasting exercise demonstrates that exchange rate pass-through to trade margins has not changed in the wake of the financial crises and the switch to inflation targeting. We also find significant inflationary effects of exchange rate changes even in the short run, an insight important for inflation targeting central banks.

China's impact on South African trade and inflation

There has been much controversy about the impact of Chinese growth on the rest of the world. It is generally accepted that China has a dampening effect on global inflation through the supply of cheap products. On the other hand, imports from China could displace domestic production and hence have adverse effects on economic growth and employment. Thus, the question of whether a country benefits from trading with China is a country-specific issue. The results in this paper indicate that limited short-term costs have resulted from the strengthening of trade relations between South Africa and China. As far as inflation is concerned, the paper does not find convincing empirical evidence at the aggregate level for inflation in China leading to domestic price changes. At the disaggregate level, however, there appear to be stronger sector-specific linkages between prices in China and South Africa.

Inflation,economic activity and the operation of fiscal,foreign and monetary impulses in the Netherlands — A preliminary analysis, 1953–1973

Summary This paper tests both the strong and weak versions of the fiscal, foreign and monetary impulse hypotheses holding that each of these impulses is either a sufficient or a necessary condition for fluctuations in price and output to occur.Four impulses are distinguished: a fiscal impulse being a linear combination of autonomous changes in government expenditures and taxes, two foreign impulses measured by the growth rates of world trade and import prices, and a monetary impulse measured by (changes in) the growth rate of the stock of domestic or world money.When tested against the Dutch post-war experience of inflation and output fluctuations, all strong impulse hypotheses have to be rejected, as do the weak fiscal and foreign world trade hypotheses with respect to inflation and the weak fiscal hypotheses with respect to output growth. The weak foreign and monetary impulse hypotheses of output fluctuations, however, and the weak foreign import price and monetarist hypotheses of inflation are not rejected.     

全球化、全球产出缺口与国内的通货变动

本文运用开放条件下的菲利普斯曲线模型对美国、日本、欧元区和中国四个样本国家进行实证检验,考察了全球化下国内通货变动的影响因素,探讨了全球化对国内通货变动的影响渠道。结果发现,"全球产出缺口假说"在各国基本成立。工业化国家全球产出缺口对国内通货变动的影响程度明显高于中国,原油和食品等初级产品的价格对国内物价的影响也更为显著。对待全球化背景下中国的通货变动,不仅要分析国内宏观经济均衡与波动周期,更要关注国际市场的外部冲击。国内政策工具的使用要根据国内国际经济周期的变化准确把握时机和力度,同时还要加强与其他国家的经济合作与政策协调。     

Globalization and Inflation: a Swiss Perspective

Is inflation caused by global developments instead of domestic monetary factors? This paper explores the role of globalization for inflation, especially in Switzerland, one of the smallest and most open economies where the globalization hypothesis should be most relevant. It provides tests of whether Swiss inflation is causally related to inflation elsewhere. It also examines Swiss inflation in a P* model and whether it is also influenced by inflation abroad or by import prices. It finds that Swiss inflation is made at home. Evidence is presented of a co-integrating relationship of Swiss and German inflation, likely due to common inflation objectives.     

On the Sources of Inflation in Kenya: A Model‐Based Approach

We develop a semi‐structural new‐Keynesian open‐economy model – with separate food and non‐food inflation dynamics to study the sources of inflation in Kenya in recent years. To do so, we filter international and Kenyan data (on output, inflation and its components, exchange rates and interest rates) through the model to recover a model‐based decomposition of most variables into trends (or potential values) and temporary movements (or gaps) – including for the international and domestic relative price of food. We use the filtration exercise to recover the sequence of domestic and foreign macroeconomic shocks that account for business cycle dynamics in Kenya over the last few years, with a special emphasis on the various factors (international food prices, monetary policy) driving inflation. We find that while imported food price shocks have been an important source of inflation, both in 2008 and more recently, accommodating monetary policy has also played a role, most notably through its effect on the nominal exchange rate. We also discuss the implications of this exercise for the use of model‐based monetary policy analysis in sub‐Saharan African countries.

Economic Value of Country Image: Evidence from International Trade and Implications for China

This paper examines the economic value of country image from the perspective of export prices through matching the CEPII export price data with the British Broadcasting Company country image data from 2006 to 2013. The estimation results show that positive country image has an “elevating” effect and negative country image has a “depressing” effect on export prices. The results also indicate that the lower the level of economic development of an export or import country, the stronger the export price effect of country image. As distances between export countries and trading partners increase, the elevating effect of positive country image on export prices becomes weaker. However, the depressing effect of negative country image does not become weaker over greater distances. We find that export prices are depressed by negative country image to a greater degree for China than for other countries. Therefore, it is necessary for China to prevent the occurrence of incidents detrimental to country image.     

Forward-looking agents and inflation in an oil-producing country: Evidence from Iran

A monetary model of inflation was estimated on the oil-producing country of Iran for the period 1984:1–2016:4. It was found that expectations are formed rationally and that agents are forward-looking and adjust their behavior based on changes in government expenditure. Consequently, it was found that higher fiscal variables result in lower price levels over the long run. A higher oil price leads to a lower price in the country but to a higher money supply and interest rate over the long run. Furthermore, a higher domestic interest rate results in a higher price level, while the reverse is true for a higher foreign interest rate. Another cause of inflation in Iran is the foreign price level. It was found that over the short run a higher growth of the real government expenditure results in a lower inflation rate in the country but a positive change in the foreign interest rate brings in a higher inflation rate.     

Exchange Rate and Inflation Dynamics in a Resource Rich Setting: The Case of Zambia

This paper investigates the relationship between copper prices, the exchange rate and consumer price inflation in Zambia using a structural vector autoregression with quarterly data for 1995–2014 and a combination of sign and zero restrictions to identify relevant global and domestic shocks. The paper makes two contributions. First, it provides new measures of exchange rate pass through (ERPT), based on less restrictive assumptions than previous estimates, to show how changes in the value of the kwacha are reflected in changes in consumer prices (distinguishing food and non‐food inflation). Second, the ERPT is disaggregated to demonstrate that measured ERPT depends on the nature of the shock, with implications for policy responses. Although the price of copper is the most important driver of the exchange rate, the fluctuations it caused are associated with a low pass‐through of about 7% (consistent with a period of relatively low inflation). Exchange rate fluctuations caused by monetary shocks, in contrast, come with a pass‐through of up to 25% (and even more for food prices). A fast response by monetary authorities can mitigate the adverse effects of exchange rate shocks.
