On the dynamics of inflation persistence around the world

We study the dynamics of inflation persistence in 45 countries for the period 1960–2008 using a recently developed test for multiple changes in persistence, which decomposes the sample information between adjacent I (0) and I (1) periods. We find that: (i) inflation persistence and average inflation tend to fall and rise at the same time; (ii) in some countries there are changes in the level of inflation which do not seem to be related to changes in inflation persistence; (iii) around half of the countries analyzed do not present any burst of I (1) behavior, and hence have stationary inflation throughout; (iv) for the other half, we detect switches of the type I (0) ? I (1) ? I (0), hence, inflation persistence, when it has occurred, has been temporal; and, (v) for about half of the countries in which inflation has presented I (1) behavior, persistent inflation lasted more than a decade. In addition, we find that in the last 50 years there have been mainly two episodes where long bursts of I (1) inflation took place simultaneously among groups of countries. In general, the “Great Inflation” occurred during the seventies and eighties in advanced economies, whereas it occurred during the eighties and nineties in emerging economies, particularly in Latin America.     

Inflation persistence in central and eastern European countries

This article studies inflation persistence with time-varying coefficient autoregressions for 12 central European countries in comparison with the United States and the euro area. We find that inflation persistence tends to be higher in times of high inflation. Since the oil price shocks, inflation persistence has declined both in the United States and the euro area. In most central and eastern European countries, for which our study covers 1993–2012, inflation persistence has also declined, with the main exceptions of the Czech Republic, Slovakia and Slovenia, where persistence seems to be rather stable. Our findings have implications for the conduct of monetary policy and for a possible membership in the euro area. Among the two time-varying coefficient methods we use, our results favour the flexible least squares smoother over the Kalman smoother. We also conclude that the OLS estimate of an autoregression is likely upward biased relative to the time-average of time-varying parameters, when the parameters change.     

Decomposing World Income Distribution: Does The World Have A Middle Class?

Using the national income/expenditure distribution data from 111 countries, we decompose total inequality between the individuals in the world, by continents and regions. We use Yitzhaki's Gini decomposition which allows for an exact breakdown of the Gini. We find that Asia is the most heterogeneous continent; between-country inequality is much more important than inequality in incomes within countries. At the other extreme is Latin America where differences between the countries are small, but inequalities within the countries are large. Western Europe/North America is fairly homogeneous both in terms of countries' mean incomes and income differences between individuals. If we divide the world population into three groups: the rich (those with incomes greater than Italy's mean income), the poor (those with incomes less than Western countries' poverty line), and the middle class, we find that there are only 11 percent of people who are "world middle class"; 78 percent are poor, and 11 percent are rich.     

Monetary union in Latin America: an assessment in the context of optimum currency area

The article applies the optimum currency area (OCA) theory to Latin America to assess the potential of a monetary union in Latin America and in its major existing regional trade agreements (RTAs). According to OCA criteria we find that Latin America is far from being an optimum currency area, as its countries’ exposure to asymmetric shocks is high and their capacities to adjust in response to macroeconomic disturbances are limited. Using a panel of 20 Latin American countries from 1990 to 2014, we apply the dynamic OLS estimation techniques to estimate the costs and benefits of a potential monetary union in Latin America and in its various RTAs. to estimate the costs and benefits of a potential monetary union in Latin America and in its various RTAs. We find that the costs are high, because Latin America’s economies are vulnerable to severe macroeconomic disturbances and its RTAs differ significantly in their response to negative demand shocks. Most of the monetary efficiency gains are shown to be the result of a common restrictive monetary policy which would result in higher FDI inflows and, to a more limited extent, increased GDP, both overall and per capita. Although Central American countries are shown to be most suitable for further monetary integration, we conclude that Latin American countries should head first towards greater economic and political integration.     

Inflation Targeting and Inflation Persistence

This paper argues that the adoption of an inflation target reduces the persistence of inflation.We develop the theoretical literature on inflation persistence by introducing a Taylor Rule for monetary policy into a model of persistence and showing that inflation targets reduce inflation persistence.We investigate changes in the time series properties of inflation in seven countries that introduced inflation targets in the late 1980s or early 1990s.We find that the persistence of inflation is greatly reduced or eliminated following the introduction of inflation targets.     

Economic development and inflation: a theoretical and empirical analysis

This paper studies the relation between inflation and economic development. The literature is largely silent regarding both the theoretical and empirical perspectives that undeveloped countries endure higher average inflation than developed economies. We present a simple theoretical model linking the inflation phenomenon to the tradition of development economics. Empirical evidence is garnered to test the hypothesis that economic development engenders a downward bias to inflation rates. Through the feasible-GLS estimator in a panel of 65 countries from 2001 to 2011, we aim at listing a number of variables most commonly used to explain differences in the stage of economic development across countries and identifying the most statistically relevant ones to account for differences in inflationary patterns. While our results show that inflation is inversely correlated with the level of the technological content of the economy (measured by share of high-tech exports), human capital and cyclical unemployment, it is directly related to the degree of inflation persistence and terms of trade growth. However, our findings still present an inverse and low correlation between inflation persistence and economic development, implying that development-sensitive variables allowed into the model can only partially account for the differences in inflation at different levels of economic development.     

Time-varying persistence in US inflation

The persistence property of inflation is an important issue not only for economists, but especially for central banks, given that the degree of inflation persistence determines the extent to which central banks can control inflation. Further, not only is it the level of inflation persistence that is important in economic analyses, but also the question of whether the persistence varies over time, for instance, across business cycle phases, is equally pertinent, since assuming constant persistence across states of the economy is sure to lead to misguided policy decisions. Against this backdrop, we extend the literature on long-memory models of inflation persistence for the US economy over the monthly period of 1920:1–2014:5, by developing an autoregressive fractionally integrated moving-average-generalized autoregressive conditional heteroskedastic model with a time-varying memory coefficient which varies across expansions and recessions. In sum, we find that inflation persistence does vary across recessions and expansions, with it being significantly higher in the former than in the latter. As an aside, we also show that persistence of inflation volatility is higher during expansions than in recessions. Understandably, our results have important policy implications.     

Does a threshold inflation rate exist? Quantile inferences for inflation and its variability

Using quantile regressions and cross-sectional data from 152 countries, we examine the relationship between inflation and its variability. We consider two measures of inflation—the mean and median—and three different measures of inflation variability—the standard deviation, relative variation, and median deviation. All results from the mean and standard deviation, the mean and relative variation, or the median and the median deviation support both the hypothesis that higher inflation creates more inflation variability and that inflation variability raises inflation across quantiles. Moreover, higher quantiles in both cases lead to larger marginal effects of inflation (inflation variability) on inflation variability (inflation). We particularly consider whether thresholds for inflation rate or inflation variability exist before finding such positive correlations. We find evidence of thresholds for the effect of inflation (inflation variability) on inflation variability (inflation). That is, for low inflation (inflation variability) countries, inflation (inflation variability) does not affect inflation variability (inflation).     

The effects of trade,aid, and investment on China's image in Latin America

Using repeated cross-sectional survey data, we analyze whether China's growing economic engagement in Latin America has an effect on citizens’ perceptions of China within 18 Latin American countries over the 2002–2013 period. Our instrumental-variables regressions exploit exogenous variation in the supply of Chinese exports, aid, and investment. Specifically, we use China's market penetration of developing countries outside of Latin America as the instrumental variable. In contrast to the widespread criticism, we do not find evidence that China's growing economic activities in the respective countries diminish average attitudes towards China—neither at the national nor at the provincial level. However, China's economic engagement appears to contribute to more polarized opinions on China: more individuals develop either very positive or very negative opinions on China. We interpret this as suggestive evidence that China's economic engagement creates winners and losers.     

Unemployment persistence in OECD countries after the Great Recession

The 2008 economic downturn in the United States resulted in a wave of contractionary effects across many OECD countries. This paper investigates the pattern of the unemployment persistence in the United States and other 28 OECD countries before and after the Great Recession. To detect possible changes in the pattern of unemployment persistence, we employ a mean bias-corrected estimation of the persistence parameter with a rolling window of five years. In addition, we estimate the most likely date of change in the trend function of unemployment to test whether there was any significant change in the pattern of unemployment persistence after the Great Recession. We find significant evidence of a structural break and hysteresis in unemployment rates, with a persistence parameter close to unity, across the United States and other 28 OECD countries. Besides, bootstrap permutation tests show that all half-lives and impulse response functions have significantly changed after the Great Recession. Therefore, our findings call for structural reforms aimed at improving labor market performance, to prevent upward shifts in unemployment across OECD countries from becoming permanent.     

Inflation targeting in Latin America: Empirical analysis using GARCH models

This paper studies inflation dynamics in eight Latin American countries, some of which have adopted formal inflation targets (IT) as their monetary policy frameworks. We analyze the possible benefits associated with IT, not only in terms of inflation level and volatility, but also regarding other nonlinear characteristics of these series, such as volatility persistence or the fulfillment of the Friedman hypothesis. To describe inflation dynamics we use an unobserved components model, where each component can follow a GARCH type process. Once we estimate the model, the main findings of the empirical exercise confirm the favorable performance of IT.     

Non-linearity in the inflation–growth relationship in developing economies: Evidence from a semiparametric panel model

Using data on developing economies, we estimate a flexible semiparametric panel data model that incorporates potentially nonlinear effects of inflation on economic growth. We find that inflation is associated with significantly lower growth only after it reaches about 12 percent, which is notably lower than the comparable estimate obtained from a threshold model. Our results also suggest that models with restrictive functional form assumptions tend to underestimate marginal effects of inflation on economic growth. We also document significant variation in the effect of inflation on growth across countries and over time.     

Do inflation targets anchor inflation expectations?

We suggest a simple test of whether an inflation target anchors private-sector inflation expectations. The test is easy to compute and it is robust to various sources of misspecification. The test may be a useful alternative to dispersion measures commonly studied in research on inflation targeting. Using data for 22 inflation targeting countries, we find for many countries that the forecasters scatter their inflation forecasts away from the inflation target. We account for the endogeneity of inflation targets, we study the variability of our finding across countries and across time, and we study to which extent our results depend on the level and variability of inflation targets.     

Latin America after the global crisis: the role of export-led and tradable-led growth regimes

Is the ongoing economic slowdown in industrialized countries likely to impact Latin American growth negatively in the medium- to long-run? This paper considers various transmission channels that work through trade in goods and services, and finds econometric evidence suggesting that shrinking global imbalances may create problems for Latin America. Specifically, using panel data analysis, we find that the trade balance as a proportion of GDP is positively associated with Latin American economic growth over the period 1953–2009. We then develop a simple dynamic model to help explain our main finding through investment and saving behaviour.     

Testing similarities of short-run inflation dynamics among EU-25 countries after the Euro

In this paper, we introduce two new definitions of pair-wise and multi-wise similarity between short-run dynamics of inflation rates in terms of equality of forecast functions and show that in the context of invertible ARIMA processes the autoregressive metric introduced by Piccolo (1990) is a useful measure to evaluate such similarity. Then, we study the similarity of short-run inflation dynamics across European Union (EU)-25 Member States during the Euro period. Consistent with studies on inflation differentials and inflation persistence, our findings suggest that after seven years from the launch of the Euro the degree of similarity of short-run inflation dynamics across Euro area countries is still weak. By contrast, we find that EU countries not adopting the common currency, whether old EU or new accession Members, display a higher degree of inflation dynamics similarity both among each other and with Euro area countries.     

Elections, exchange rates and reform in Latin America

In this paper, we study the link between real exchange rate (RER) depreciation and elections in Latin America. Our contribution is threefold. First, we employ a statistical model that takes into account the pervasive conditional heteroskedasticity found in financial data and includes a wide range of macroeconomic variables as regressors. Second, we test whether the wave of central bank reform that swept the region has had any effect on the existence or strength of the electoral cycle in exchange rates. Third, we test an additional hypothesis, namely, that financial liberalization may also be an important variable explaining changes in electoral effects on the real exchange rate. In a panel of 9 Latin American countries with available macroeconomic data and a history of exogenous election dates, we confirm the previous findings that real depreciation intensifies after elections even when modeling the significant conditional heteroskedasticity in these data. We also show, for the first time in the literature, that post-election exchange rates are significantly less predictable. We go on to test whether central bank reform has influenced the way in which elections affect the RER in Latin America. If reform has been effective at reducing political manipulation of the exchange rate, then any relationship we see between elections and the RER before central bank reform should be mitigated in the post-reform era. We find that the relationship disappears after reform and that post-reform real exchange rates are also significantly less volatile. Finally, we show that financial liberalization seems to have a stronger effect on the conditional variance of the RER than does central bank reform, but reform has a stronger impact on the conditional mean.     

Inflation persistence in the Euro area before and after the European Monetary Union

This paper provides new evidence on inflation persistence before and after the European Monetary Union (EMU). Taking into account fractional integration of inflation, we confirm that inflation dynamics differed considerably across Euro area countries before the start of EMU. Since 1999, however, results obtained from panel estimation indicate that the degree of long run inflation persistence has converged. In line with theoretical predictions, we find that the persistence of inflation has significantly decreased in the Euro area, probably as a result of the more effective monetary policy of the ECB.     

On the persistence of prices in Mexico: a fractional integration approach

A relevant yet often overlooked characteristic of the inflation rate is its mean-reverting property. If a series has this feature, shocks eventually dissipate, whereas if it does not, they have a permanent effect on the series. The usual I(1) versus I(0) dichotomy in time-series econometrics goes only so far towards disentangling this issue. By employing a methodology that estimates the persistence of inflation by allowing (i) fractional integration and (ii) persistence and level shifts in the series, we aim to define whether it is stationary and/or mean reverting and, if so, during which periods. The results of our analysis for the period 1987–2015 are threefold: firstly, inflation in the eighties and nineties should be seen as a highly persistent yet mean-reverting process (not a random walk); secondly, inflation remained mean reverting, though became a short-memory (less persistent) process around the date of the implementation of the inflation-targeting framework of 2001; thirdly, during the later phase, the level of inflation also decreased and is now within the inflation target range set by Banco de México, namely 3 per cent with an interval of ±1 percentage point.     

Central Bank Independence,Inflation and Uncertainty: The Case of Colombia

Colombia undertook reform of its central bank in 1991, pushing it in the direction of greater independence. We find that this reform led to a significant decrease in the level of inflation, as well as inflation uncertainty, suggesting an increase in credibility. However, there has also been an increase in inflation persistence since reform. The lower mean but greater persistence of inflation indicates that central bank independence has shifted the Phillips curve inward but also flattened it, a result consistent with recent research for the Euro-zone and the United States. Finally, further analysis reveals that, in accordance with the Friedman-Ball hypothesis, higher inflation raises uncertainty in Colombia, but that uncertainty does not increase inflation.     

How credible is inflation targeting in Asia? A quantile unit root perspective

This article examines the dynamic behavior of the inflation rate for eight Asian countries using a quantile unit root test. We advocate a three-way definition of inflation targeting based on perfect, imperfect and zero credibility and advance the analysis by incorporating a fully-fledged adoption of inflation targeting. In doing so, we offer new insights by showing that the credibility of inflation targeting and the alternative monetary policy frameworks in Asia are imperfect, except for Malaysia and South Korea under a fully-fledged adoption of inflation targeting. In contrast to past studies that focus on the mean-reversion in inflation rates, we also consider trend-reversion and find that Asian inflation targeting countries have been building up their monetary policy credibility more than the non- inflation targeting countries in terms of a faster rate of decline in inflation rate changes. Our results generally indicate the presence of mean reversion at the lower quantiles only. Where stationarity is present, we find evidence of a varied speed of adjustment process across the quantiles. Finally, we determine the threshold levels whereby inflation becomes stationary and demonstrate that Asian inflation rates generally display stationary behavior during periods of inflation declining or slowing down.
