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.     

ARE AFRICAN CENTRAL BANKS SUFFICIENTLY INDEPENDENT FOR MONETARY CONVERGENCE?

Central bank independence (CBI) is currently a widely debated and topical issue commanding the centre point of many economical and political debates, filling the pages of many scholarly journals. Both central bank independence and accountability are currently regarded as necessary best practices for achieving price stability. The importance of CBI rests on the premise that inflation is primarily a monetary phenomenon, and that the cost of reducing inflation can be lowered by an independent central bank with credibility. Support for CBI also stems from the argument that the power to create money should generally be separated from the power to spend it. This is even more relevant for countries with weak political institutions. However, various studies (cited below) detected lower inflation in those countries where independence of their central banks is the strongest. Countries all over – including some on the African continent – have increased the independence of their central banks accordingly.     

MEASURING INFLATION CREDIBILITY: RESULTS OF A FIRST REPRESENTATIVE SOUTH AFRICAN SAMPLE

This study reports the measurement of inflation credibility of a representative sample of the South African population in terms of an inflation credibility barometer. The barometer is an instrument measuring the degree of acceptance of the accuracy of historic inflation figures. These research results serve as a benchmark for South Africa, as similar measurement of a representative sample has not been undertaken before. The sampling results show little public understanding of the rate of inflation and its measurement of average price increases experienced by an average household. As generally accepted international benchmarks for successful central-bank communication strategies do not exist, the application of the methodology reported in this paper can improve the effectiveness of central bank communication aimed at improving the general knowledge about inflation.     

Disinflation costs, accelerating inflation gains, and central bank independence

Disinflation Costs, Accelerating Inflation Gains, and Central Bank Independence. - This paper considers the impact of central bank independence on both the costs of disinflation and the gains of accelerating inflation. For this purpose, sacrifice ratios for disinflation episodes and benefice ratios for accelerating inflation episodes are constructed by using a new method. The ratios are calculated for 19 industrial countries over the period 1960–1992. The results indicate that central bank independence only matters during disinflation episodes: Sacrifice ratio and output loss are higher, the more independent the central bank is; whereas during accelerating inflation episodes, central bank independence has no influence on either the benefice ratio or the output gain.     

House Prices and the Stance of Monetary Policy: The Case of Korea

Abstract

This paper is an empirical investigation on whether the Bank of Korea should respond to the housing price developments in conducting monetary policy. For that aim, we construct a small scale empirical model of the Korean economy, simulate the estimated model with a set of alternative monetary policy rules, and compare the stabilization performances of those rules. There turns out to be ample room for further stabilization of inflation and output, if the central bank shifts from the historically conducted monetary policy rule to the optimal rule. The stabilization gains under the optimal rule, however, are not attributable to additional policy indicators (such as housing price inflation) the optimal rule involves. Rather, the optimal rule improves upon the historical one because the former takes a quite different reaction scheme toward the historical policy indicators. Moreover, as long as the Bank of Korea maintains appropriate reactions to the historical policy indicators, housing price inflation does not contain much extra information for further stabilization     

THE SENSITIVITY OF SOUTH AFRICAN INFLATION EXPECTATIONS TO SURPRISES

Price stability is widely recognised as the primary goal of modern monetary policy, and the management of private sector inflation expectations has become an essential channel through which this goal is achieved. This evaluation aims to improve the understanding of how the sensitivity of private sector inflation expectations to macroeconomic surprises in South Africa compares internationally, as this provides an indication of the contribution of monetary policy in South Africa to anchoring inflation expectations. If a central bank is credible, the financial markets should react less sensitively to macroeconomics surprises, because they trust the central bank to manage these incidents and achieve the objectives they communicated over the medium to long term. In this paper, the methodology of Gurkaynack et al. is adopted in order to measure the sensitivity of South African inflation expectations to surprises. A comparison of South Africa's results with those of countries in the original studies supports the contention that the SARB (South African Reserve Bank) has encouraged inflation expectations to be relatively insensitive to macroeconomic surprises, and offers support for the inflation-targeting framework as a means to help anchor inflation expectations.     

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.     

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.     

Exchange Rate Variability and the Macro-economy: Evidence from Developing and Developed Countries

Abstract

Using annual data, the paper studies the time-series evidence regarding the allocation of fluctuations in the exchange rate between demand components, real growth, and price inflation in a sample of developing and advanced countries. The evidence reveals patterns of interaction between the macro-economy and exchange rate variability. Across developing countries, appreciation decreases the cost of imports and price inflation, while depreciation shrinks the output supply, indicating high dependency on imported goods. The reduction in output supply correlates with higher inflation and an increase in the import value. In contrast, the evidence of the negative effect of currency appreciation on output growth is more prevalent across advanced countries, while depreciation stimulates competitiveness, resulting in higher demand for exports, investment and consumption. Across developing countries, exchange rate variability decreases trend real growth and increases trend price inflation. Across advanced countries, exchange rate variability decreases trend real growth while increasing the variability of price inflation and import growth. Minimizing variability of the exchange rate would be beneficial to sustain higher growth and reduce cyclical variability in developing and advanced countries.

The role of import prices in flattening the Phillips curve: Evidence from Korea

Are global inflation synchronization and the flattening of the Phillips curve across the globe related? The globalization hypothesis has been proposed to explain the relationship but questions remain on its quantitative role. Focusing on South Korea, one of Asia-Pacific supply chain hubs, this paper investigates the extent to which import prices affect domestic price inflation over the period between 2002 and 2020. Specifically, we conduct the regression decomposition method to identify major sources of variation in domestic inflation, followed by a subsequent set of comparative analyses across various inflation forecasting models. Our findings confirm a tight link from import prices to domestic prices, with a 10pp increase in IPI inflation passed onto PPI and CPI inflation by 3.9pp and 3.4pp over time, respectively. The main finding of this study is consistent with the recent global inflation surge that has been driven largely by imported food and energy price channels.     

Too Many Cooks? Committees in Monetary Policy

How many people should decide monetary policy? In this article, we take an empirical perspective on this issue and analyze the relationship between the number of monetary policy decision makers and monetary policy outcomes. Using a new data set that characterizes central bank monetary policy committees (MPCs) in more than 30 countries from 1960 through 2006, we find a U‐shaped relationship between MPC size and inflation; our results suggest that the lowest level of inflation is reached at MPCs with an intermediate size of about five to nine members. Similar results are obtained for inflation variability. Other MPC characteristics also matter for monetary policy outcomes, though to a smaller degree. For instance, the membership composition of the MPC as well as the frequency of MPC membership turnover appears to affect economic variables.     

A nonnormative theory of inflation and central bank independence

A Nonnormative Theory of Inflation and Central Bank Independence. — The authors study monetary policy under different central bank constitutions when the labor-market insiders set the minimal wage so that the outsiders are involuntarily unemployed. If the insiders are in the majority, the representative insider will be the median voter. The authors show that an independent central bank, if controlled by the median voter, does not produce a systematic inflation bias, albeit equilibrium employment is too low from a social welfare point of view. A dependent central bank, in contrast, is forced by the government to collect seigniorage and to take the government’s re-election prospects into account. The predictions of their theory are consistent with the evidence that central bank independence decreases average inflation and inflation variability, but does not affect employment variability.     

通胀、通胀预期和货币政策——基于中国2001—2010年数据的实证研究

文章用两种方法测度了我国通胀预期：（1）未来物价预期指数衡量通胀预期;（2）ARMA模型对通胀的预测值。并计量分析了影响通胀预期的因素,结果显示：CPI上升、正产出缺口增加和广义货币供应量增加,是形成通胀预期的主要因素。利率、人民币汇率和食品价格对通胀预期的形成作用不显著和影响较小。因此,存款准备金率动态微调,是目前管理好通胀预期的最好选择。     

A NOTE ON THE TRIMMED MEAN MEASURE OF CORE INFLATION IN SOUTH AFRICA

This paper constructs and analyses the properties of a trimmed mean inflation rate for South Africa. Based on an analysis of the distributions of the consumer price index component price changes, a measure is constructed that provides an estimator of core inflation, which may be particularly useful to policymakers in an inflation‐targeting environment. The trimmed mean estimator focuses on the price movements of individual components that have a strong bearing on the current and future trend of the headline inflation rate, allowing monetary policy to be directed at the persistent or underlying sources of inflationary pressures.     

Some aspects of the impact of inflation on the debt burden of developing countries

The effect of inflation on the external indebtedness of developing countries is examined in this UNCTAD paper in a more comprehensive framework than is usually the case. The conventional view on this has been that international inflation reduces the ‘real’ burden of external debt. However, viewed in the context of the net effect of inflation on the import capacity of debtor developing countries, the paper shows that the situation is by no means so simple. It demonstrates by examining the cases of a sample of 71 developing countries that the effect of price increases of developing countries' imports (relative to price increases for their exports) caused by international inflation can and often has more than offset the so-called favourable effect on the burden of debt. For example in 1975, a year with particularly high inflation, no less than 75% in the sample experienced negative consequences. In these cases, therefore, international inflation on balance has reduced import capacity and thus made it more not less difficult for them to maintain servicing on their external debt and so increased the ‘real’ burden of their debt. Thus the UNCTAD paper brings into serious question the conventional wisdom on this important issue.     

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.     

Mix of Fiscal and Monetary Policy Rules and Inflation Dynamics in China

The present paper examines the role of the mix of fiscal and monetary policy rules in determining inflation dynamics using fiscal and monetary policy reaction functions and Markov‐switching vector autoregression methods based on quarterly data in the period 1992–2007. Our results show that fiscal and monetary policies in China can be adequately described using some simple rules, and that significant regime shifts took place around 1998. Fiscal policy tended to be active and countercyclical in the pre‐1998 period, then switched to be passive and more countercyclical, whereas monetary policy was characterized as passive and procyclical in the pre‐1998 period, and switched to be active and countercyclical afterwards. The mix of fiscal and monetary policy rules can explain inflation dynamics better than the monetary policy rule alone. Therefore, price stability requires not only appropriate monetary policy but also appropriate fiscal policy.     

De gevolgen van de directe prijsbeheersing voor de internationale handel

Summary This paper contains a theoretical analysis of how a maximum price being put on homogeneous commodities affects international trade if rates of exchange are fixed. The consequences of a calculation scheme for fixing prices of differentiated products are also investigated.A maximum price that is lower than the import price is an impediment to import. This leads to oscillations of the import price if demand in the importing country is sufficiently high. The maximum price has no influence if it is higher than the import price. A maximum price that is equal to the export price (which is independent of the supply of the exporting country) retards the decline of export that would occur in consequence of a rise in home demand or a rise in costs of production. As soon as the average revenue per unit of product exported exceeds the maximum price, suppliers will try to export as much as possible. Importation of substitutes is stimulated indirectly and exportation of substitutes is discouraged, whereas the opposite effects occur with respect to complementary goods, materials used in the production process, and goods for the production of which the same materials and factors of production are used.If demand rises, a calculation scheme used for price control will reduce imports and stimulate exports. The calculation scheme reacts only on rises in costs of production that are not recognized officially by the government: imports will be smaller, and exports higher, than in the case of a free determination of prices. Calculation schemes check the importation of substitutes and stimulate their exportation, whereas the opposite effects may occur with respect to complementary goods, or due to changes in the production.In case of a general control of prices when inflation prevails, the whole set of price effects will affect the balance of payments. However, the final result will be uncertain, since some price effects tend to enhance the surplus of the balance of payments whereas others tend to reduce it. At the same time, income effects may affect the balance of payments in the adverse sense.National price control impedes the optimum allocation of resources in an economic community. This is due to the fact that it distorts trade.     

The choice of the inflation rate as a target in an economy with pricing-to-market

This article verifies an effect caused by introducing alternative inflation targeting in a two-country economy model by following the new open-economy macroeconomics trend of incorporating pricing-to-market behavior among firms. Previous research suggests that, from the point of view of stabilizing output and inflation, central banks must choose producer price inflation as a target under the assumption that purchasing power parity applies. This paper, however, with a revived conventional pricing-to-market model, indicates that a central bank must choose consumer price inflation, not producer price inflation, from the point of view of stabilizing output and inflation.
