Nonlinearity and stationarity of inflation rates: evidence from the euro-zone countries

Earlier studies hardly reject the hypothesis of a unit root in inflation. Few studies have examined the possibility of nonlinearity in inflation and tested nonlinear stationarity of the inflation rates. This study thus intends to fill the gap. This study utilizes the tests for nonlinearity along with the unit root tests that allow for nonlinearity in the variables to examine the stationarity of inflation rates of 12 European countries that formed the Euro Zone (EZ) later in the sample period. The results suggest that the majority of these countries’ inflation rates can be characterized by mean reversion during the floating exchange rate period. Many of them appear to be nonlinear stationary. This finding is essential in conducting applied economic studies for these countries, when constructing models whose validity relies on whether or not inflation is stationary. The results of this study also imply that shocks to inflation have a transitory effect on inflation in the euro area. Therefore, it would be less costly in exercising the policies of disinflation for the monetary authorities of the euro area than for those of the countries with nonstationary inflation.     

An empirical evaluation of China’s monetary policies

This paper investigates the responsiveness of the Chinese government’s monetary policies in terms of the money supply and interest rates to economic conditions and the effectiveness of these policies in achieving the goals of stimulating economic growth and controlling inflation. We analyze the responsiveness and effectiveness by estimating the Taylor rule, the McCallum rule, and a vector autoregressive model using quarterly data in the period of 1992-2009. The results show that, overall, the monetary policy variables respond to economic growth and the inflation rate, but the magnitudes of the responses are much weaker than those observed in market economies. Money supply responded actively to both the inflation rate and the real output and had certain effects on the future inflation rates and real output. The official interest rates, on the other hand, responded passively to the inflation rate and did not respond to the real output. They do not have any effect on future inflation rates and real output either.     

On the real effects of inflation and inflation uncertainty in Mexico

We estimate an augmented multivariate GARCH-M model of inflation and output growth for Mexico at business cycle frequencies. The main findings are: (1) inflation uncertainty has a negative and significant effect on growth; (2) once the effect of inflation uncertainty is accounted for, lagged inflation does not have a direct negative effect on output growth; (3) However as predicted by Friedman and Ball, higher average inflation raises inflation uncertainty, and the overall net effect of average inflation on output growth in Mexico is negative. That is, average inflation is harmful to Mexican growth due to its impact on inflation uncertainty. (4) The Mexican Presidential election cycle significantly raises inflation uncertainty both during the year of the election and the year following the election which has correspondingly negative effects on output growth.     

Does inflation targeting make a difference in developing countries?

We evaluate the treatment effect of inflation targeting in thirteen developing countries that have adopted this policy by the end of 2004. Using a variety of propensity score matching methods, we show that, on average, inflation targeting has large and significant effects on lowering both inflation and inflation variability in these thirteen countries. However, the effectiveness of inflation targeting on lowering inflation is found to be quite heterogeneous. The performance of a given inflation targeting regime can be affected by country characteristics such as government's fiscal position, central bank's desire to limit the movements of exchange rate, its willingness to meet the preconditions of policy adoption, and the time length since the policy adoption.     

Exchange Rate Passthrough Effects and Inflation Targeting in Emerging Economies: What is the Relationship?

Several studies have shown that over the past 10 years the passthrough effect from currency depreciation into domestic inflation has been decreasing in emerging economies that adopted inflation targeting (IT) during the mid and late 1990s. Therefore the nominal exchange rate effect on domestic inflation is becoming less of an issue for these countries. The literature has offered different explanations for these declines but so far they have not been directly related to the adoption of IT. This paper shows that lower passthrough effects can also be the result of the implementation of an IT regime and argues, contrary to previous studies, that the effects of the nominal exchange rate on inflation are still a relevant issue for emerging IT countries. The reason for this is that the empirical evidence offered for the lower passthrough misses the nature of the relationship between inflation and the nominal exchange rate under IT.     

Inflation and income distribution in Central America,Mexico, Panama,and the Dominican Republic

Analyses of the impact of inflation on income distribution typically only consider the general inflation rate. However, when the consumption structure of households is shaped by its income level and inflation varies across goods and services, they are affected differently by inflation. The aim of this study is to contribute to the analysis of this effect in Central American countries (Guatemala, El Salvador, Honduras, Nicaragua, and Costa Rica), Panama, Mexico, and the Dominican Republic (CAPMDR) for the period 2007–2018. According to our findings, there have been significant differences in the inflation rates faced by different income groups. By employing these percentile‐specific inflation rates, we have computed an “inflation‐corrected Gini index.” This adjustment is important because although inequality has been decreasing during past years in the countries in our sample, on average, about half of the gains observed using the standard Gini index are lost once the Gini indices are corrected for inflation, a clearly nonnegligible magnitude.     

ARDL bounds tests and robust inference for the long run relationship between real stock returns and inflation in Australia

This paper conducts an empirical investigation into the long run relationship between real stock returns and inflation in Australia by employing the ARDL bounds tests. There exists a stock return–inflation long run relationship, and the long run parameters are non-linear functions of those of the conditional error correction model. The OLS estimates of the latter model constitute the long run parameter estimates and their standard errors are estimated by delta methods. The long run model estimates so constructed can be biassed and inconsistent, and the delta method is derived assuming asymptotic normality, which does not hold in this investigation. In this paper, to overcome these limitations of the traditional methods, we employ the bias-corrected bootstrap method. As a consequence, the robust and reliable statistical inference can be made on the long run return–inflation relationship. The empirical results show that the expected inflation had no significant effect on real stock returns, while the observed inflation had a significant and negative effect. Furthermore, the data generating process of the returns–inflation relationship was not affected by the change in monetary policy regime in the early 1990s. These findings imply that Australian stocks have been very effective instruments for hedging against expected inflation. Because of the resilience of Australian economy to the current global financial and economic crisis, this finding has implications for long term domestic and foreign investors in Australia.     

INFLATION,OUTPUT, AND WELFARE*

We study the effects of anticipated inflation on aggregate output and welfare within a search‐theoretic framework. We consider two pricing mechanisms: ex post bargaining and a notion of competitive pricing. Under bargaining, the equilibrium is generically inefficient and an increase in inflation reduces buyers' search intensities, output, and welfare. If prices are posted and buyers can direct their search, search intensities are increasing with inflation for low inflation rates and decreasing for high inflation rates. The Friedman rule achieves the efficient allocation, and inflation always reduces welfare, although it can have a positive effect on output for low inflation rates.     

Estimating inflation compensation for Turkey using yield curves

Inflation compensation derived from nominal and real bond yields contains market based, real time information regarding the inflation expectations and the pricing of inflation risks. In this study, we calculate inflation compensation for Turkey by using nominal and real yield curves. The findings of event study analysis on inflation compensation indicate that changes in the term structure of inflation compensation contain information regarding the credibility of monetary authority. Moreover, we find that, at daily frequency, liquidity conditions have no significant effect on inflation compensation and hence the effects of events such as monetary policy decisions and inflation surprises on inflation compensation can be attributed mainly to changes in inflation expectations and pricing of inflation uncertainty.     

Performance of inflation targeting in retrospect

Both inflation and inflation expectations declined considerably in the inflation targeting countries during the past two decades. The questions of whether this decline has actually been an outcome of inflation targeting solely and whether inflation targeting has been successful in stabilizing other macroeconomic variables though remain. This study considers these questions on the basis of 16 inflation targeting countries and 21 non-targeting ones using a difference-in-difference approach. With regard to the baseline period of 1996–1999 during which neither of the groups was implementing inflation targeting, a difference-in-difference approach was employed to assess the effects of inflation targeting on inflation, output growth, real exchange rates, inflation volatility and real exchange rate volatility during moving 4-year periods between 2007 and 2015. Our estimates suggest that inflation targeting was superior in terms of harnessing inflation as well as inflation volatility. In terms of economic growth, however, inflation targeting seems to be neutral and in terms of real exchange rates it seems not to be stabilizing, if not de-stabilizing. A hybrid version of inflation targeting, namely the conventional inflation targeting augmented by an improved capacity to deliver macro-prudence as in the post-Lehman economic climate, can therefore be viewed as the best available policy alternative for the upcoming decades.     

Time-varying transmission effects of external shocks into inflation: how different is China from Korea?

This article examined the time-varying effects of external shocks that determine inflation on Chinese and Korean consumer price index (CPI) inflation, using data from the period 2010:1 to 2013:4. For this experimentation, we adopted the Kalman filter algorithm. Key findings include the following: first, the lagged CPI inflation is the main determinant of inflation rate in both China and Korea that is significant and has positive effects. Second, as expected, the effects of independent variables on CPI inflation rate have a considerable difference in China and Korea from the coefficients’ size and sign. Especially, China’s CPI inflation is mainly affected by domestic output growth, while Korea is more readily affected by external shocks. Third, we confirmed the time-varying effects. For instance, the positive effect of the output variable is decreasing in the Chinese inflation equation, but its negative effect is decreasing in the Korean inflation equation. Finally, we can guess Korea is a more import dependent economy than China and also the trends of estimated coefficients of China’s inflation are changing similarly to Korea. It has been proved from recent changes that there is a decreasing effect of output growth, but negatively and increasing effects of exchange rate and import dependence. Hence, those recent changes imply that this is caused by the change of the Chinese economy to be more trade dependent as well as we cannot deny the possibility of the external factors that play a role in CPI inflation, and its influence is gradually increasing in China.     

The impacts of regime-switching structures and fat-tailed characteristics on the relationship between inflation and inflation uncertainty

A great of deal of study has explored the relationship between inflation and inflation uncertainty under the assumptions of normal distribution and no regime shift. This paper attempts to investigate whether changes in the specification of distribution specification and regime shifts will affect the inflation-uncertainty relationship. Empirical results show that these two factors have a vital effect on the inflation-uncertainty relationship. A specification with four states and the Student’s t distributed error terms can successfully describe the dynamics of the inflation rate. After taking the non-normal density and independent regime shifts into account, this paper finds that inflation uncertainty has no impact on inflation, regardless of inflation pressure. Inflation has a negative impact on inflation uncertainty during periods of high inflation volatility, while the impact of inflation on inflation uncertainty is insignificant during periods of low inflation volatility.     

Partisan Social Happiness

We use a new approach to study questions in political economy that relies on data on the subjective well-being of a large sample of people living in the OECD over the period 1975{1992. Controlling for the personal characteristics of the respondents, year and country fixed effects and country-specific time trends, we find that the data describe social happiness functions for left-wing and right-wing individuals where inflation and unemployment enter negatively. We use these functions to test the root assumption of partisan business cycle models. The evidence is consistent with the hypothesis that left-wing individuals care more about unemployment relative to inflation than right-wingers. Interestingly, we find that individuals declare themselves to be happier when the party they support is in power, even after controlling for macroeconomic variables. The effect of politics is large. Finally, we find that these partisan differences cannot be traced back to income differences. That is, it is misleading to assume|as it is done in the previous literature|that the poor (rich) behave similarly to the left (right). For example, inflation and unemployment do not have differential effects across rich and poor and the happiness levels of these two groups are unaffected by the identity of the party in power. Our findings are hard to explain using median voter models but are to be expected in a partisan world.

Evidence on the effects of inflation on price dispersion under indexation

Distortionary effects of inflation on relative prices are the main argument for inflation stabilization in macro models with sticky prices. Under indexation of non-optimized prices, those models imply a nonlinear and dynamic impact of inflation on the cross-sectional price dispersion (relative price or inflation variability, RPV). Using US sectoral price data, we estimate such a relationship between inflation and RPV, also taking into account the endogeneity of inflation by using two- and three-stage least-squares and GMM techniques, which turns out to be relevant. We find an effect of (expected) inflation on RPV, and our results indicate that average (??trend??) inflation is important for the RPV?Cinflation relationship. Lagged inflation matters for indexation in the CPI data, but is not important empirically in the PPI data.     

Globalization, the output-inflation tradeoff and inflation

This paper provides comprehensive evidence on the relation between inflation and globalization, defined here as trade and financial openness, using a large cross-section of 91 countries over the period 1985-2004. We establish two main empirical regularities: both higher trade and financial openness (i) reduce central banks’ inflation bias, yielding lower average inflation and (ii) are associated with a larger output-inflation tradeoff. This evidence is at odds with the standard Barro-Gordon framework, which would require globalization to have a negative effect on the output-inflation tradeoff to yield lower equilibrium inflation, but it is consistent with a recent strand of new Keynesian models emphasizing the role of imperfect competition and nominal rigidities. Our findings also support the relevance of the time-inconsistency hypothesis, which underlies the theoretical models predicting a relation between globalization and inflation. For the OECD subsample, however, we do not find an effect of openness on inflation (the output-inflation tradeoff), suggesting that these countries have created an institutional framework for central banks that eliminates distortions due to the time-inconsistency problem.     

Inflation uncertainty, growth uncertainty, oil prices, and output growth in the UK

This study examines the transmission and response of inflation uncertainty and output uncertainty on inflation and output growth in the UK using a bi-variate EGARCH model. Results suggest that inflation uncertainty has positive and significant effects on inflation before the inflation-targeting period, but that the effect is significantly negative after the inflation-targeting period. On the other hand, output uncertainty has a negative and significant effect on inflation and a positive effect on growth, while oil price rises significantly increase inflation for the UK. Results also indicate that inflation uncertainty significantly reduces output growth before and after the inflation-targeting period. These findings are robust and the Generalized impulse response functions corroborate the conclusions. These results have important implications for an inflation-targeting monetary policy, and for stabilization policy in general.     

The Welfare Effect on Different Income Groups of Indirect Tax Changes and Inflation in New Zealand

This paper has two main aims, both associated with measuring the welfare effects of price changes. First, it examines the distributional effects of the change in the indirect tax system in New Zealand during the mid-1980s. Second, it examines the distributional impact of recent inflation in New Zealand. The results confirm those of previous studies which found that indirect taxes in New Zealand did not have a substantially larger impact on low income groups compared with high income groups. Furthermore, the introduction of the goods and services tax does not appear to be regressive. However, recent price changes in New Zealand have had a higher impact on the high income groups, although this tendency is quite small.     

Money,transactions and portfolio choice

Real money balances are held separately forconsumptionandportfolioreasons. When real balances are a state variable in the investor 's optimization problem, there is a specific inflation-hedging portfolio. An investor hedges against inflation when the effect of real money holdings on the marginal utility of wealth is negative. We show that a decrease in real balances due to inflation has two opposite effects on the marginal utility of wealth. On the one hand, the decrease in real balances reduces consumption, which in turn raises the marginal utility and decreases the marginal cost of consuming: this explains why an investor would normally hedge inflation. On the other hand, the decrease in real balances tends to increase the marginal cost of consuming. When this second effect dominates, we have the somewhat surprising result that the investor reverse-hedges inflation.     

ARE THERE ADVERSE INFLATION EFFECTS ASSOCIATED WITH NATURAL GAS DECONTROL?

The Natural Gas Policy Act (NGPA) will decontrol gas prices in 1985, and there is concern about its inflation and output effects. In this investigation of these concerns, two misapprehensions are remedied. First, inflation is primarily a monetary phenomenon so that a rise in energy prices affects the price level, but any impact on inflation is temporary. Second, while analyses of NGPA have assumed that the price of gas will achieve parity with petroleum, they have neglected decontrol's effect on OPEC's optimal price, Our estimates of the decontrol effect demonstrate that energy prices will fall, not rise
