The negative side of inflation targeting: revisiting inflation uncertainty in the EMU

ABSTRACT

This article tests the Friedman–Ball hypothesis for the European Monetary Union (EMU) countries, using a GARCH methodology. The empirical results show a positive relationship between inflation and inflation uncertainty, largely supportive of the Friedman–Ball hypothesis. Furthermore, the ECB’s price stability mandate is found to have asymmetric, if not limited, effects on inflation uncertainty since 1999, with the findings different for the so-called peripheral countries when compared to the core. For the majority of the EMU countries, shifts away from the 2% target served to increase inflation uncertainty. The credibility of the ECB since the financial crisis, in attempting to meet its 2% inflation target has seen inflation uncertainty increase for some, likely driven by inflation failing to re-anchor. Furthermore, recent periods of deflation are found to generate inflation uncertainty, with short-term price variability increasing in line with observed negative price growth for the majority of the EMU countries. The results are supportive of a U-shaped relationship between inflation and inflation uncertainty. Using spline techniques, we formally provide support for such a U-shaped relation where inflation uncertainty broadly increases below a certain threshold for each country’s inflation rate. Asymmetric effects across countries are found in the level of this threshold.     

Monetary policy through the ‘credit-cost channel’: Italy and Germany pre- and post-EMU

We present an empirical analysis of the ‘Credit-Cost Channel’ (CCC) of monetary policy transmission. This channel combines bank credit supply and interest rates on loans as a cost to firms. The thrust of the CCC is that it makes both aggregate demand and aggregate supply dependent on monetary policy. As a consequence (1) credit market conditions (e.g. risk spreads) are important sources and indicators of macroeconomic shocks, (2) the real effects of monetary policy are larger and persistent. We have applied the Cointegrated Vector Autoregression (CVAR) econometric methodology to Italy and Germany in the ‘hard’ EMS period and in the European Monetary Union (EMU) period. The short-run and long-run effects of the CCC are detectable for both countries in both periods. Simulation of the estimated model also confirms that inflation-targeting by way of inter-bank rate control stabilizes inflation through structural shifts of the stochastic equilibrium paths of both inflation and the output.     

The bank lending channel of monetary policy in EU countries during the global financial crisis

The study examines the existence of the bank lending channel of monetary policy in European Union (EU) countries. The paper advances current research on the monetary transmission mechanism in the following ways: Firstly, we analyze the differences between ‘old’ Economic Monetary Union (EMU) and ‘new’ EU countries. Secondly, we examine the key bank characteristics and monetary policy indicators that may have an impact on the bank lending channel. We assume that short-term market interest rates and monetary aggregate M2 affect banks' activities. We apply the generalized method of moments (GMM) with pooled data from 1999 to 2012. We show that in the pre-crisis period the effect of changing the short-term market interest rates on the bank lending channel of monetary policy is more pronounced among ‘old’ EMU countries, whereas the effect of M2 is significant during the period of the global financial crisis (GFC) among ‘old’ EMU countries. Last but not least the important finding is that banks in ‘new’ EU countries react differently to monetary shocks.     

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.     

Productivity Trends in Europe: Implications for Real Exchange Rates, Real Interest Rates, and Inflation

The paper examines a long–run (neoclassical) framework in which differences in productivity growth across sectors and countries lead to inflation differentials. In a currency union, these inflation differentials imply cross–country differentials in real interest rates. The authors estimate the likely size of these differentials for European Union countries, discuss the potential costs of persistent inflation differentials, and comment on the conflicts they may cause within Economic and Monetary Union (EMU). The analytical framework is a variant of the Balassa–Samuelson "productivity hypotheisis," which relates sectoral productivity trends to trends in the relative price of home goods.     

Wages and prices in Europe before and after the onset of the Monetary Union

This paper investigates possible structural changes induced by the Euro on the relations among wages, prices and unemployment for the five major European economies. The dynamic adjustment and the level relations are found to be different across subperiods as well as across countries. During the European Economic and Monetary Union (EMU) period, there is evidence of a conventionally-sloped Phillips Curve for the four economies within the EMU, with a higher degree of homogeneity with respect to the pre-EMU period; the UK presents instead a positively-sloped Phillips Curve in the EMU period. In this latter period, deviations from reference values are found to influence unemployment for all countries, including the UK. Only for Germany and Spain, instead, we find evidence that deviations from reference values influence inflation dynamics.     

Is There a Trade‐Off Between Inflation Variability and Output‐Gap Variability in the EMU Countries?

This paper examines the performance of monetary policy in eleven EMU countries for the whole period of the EMS. This is based on the trade‐off between inflation variability and output‐gap variability. To this end, we examine whether the introduction of an implicit inflation targeting by the EMU member countries after the Maastricht Treaty, changed the trade‐off between inflation variability and output‐gap variability. We employ a stochastic volatility model for two sub‐periods of the EMS (i.e. before and after the Maastricht Treaty). We find that the trade‐off varies amongst EMU countries. The implication of these findings is that there are asymmetries in the euro area, due to different economic structures among the member countries of the EMU.     

A simple inflation indicator for the euro zone

This article proposes and estimates an inflation indicator for the European Monetary Union (EMU). This indicator is set up so that it is contemporarily not affected by the changes in price differentials among EMU countries. The results show that the Monetary Union Index of Consumer Prices (MUICP), which is the inflation measure that the European Central Bank (ECB) takes as a reference for monetary policy purposes, could be understating the value of the inflation in the euro zone. It is also concluded that regional peculiarities are fundamental in the evolution of prices in the different EMU countries.     

Market power and efficiency

This paper introduces new measures of the mean and variance of inflation and growth expectations, based on tendency survey data from four major European economies. The expectations measures are technically ‘irrational’, but more accurate than naive alternatives; expectations errors do not persist for more than a year. Unexpected inflation, and uncertainties about inflation and growth, play the roles assigned them by New Classical macroeconomic theory, respectively raising and lowering real activity. All the expectations, uncertainties and errors appear more closely correlated across countries than experience would justify, suggesting that unpredictable disturbances typically have an internal rather than an international origin.     

Dynamics of Government revenues and expenditures in industrial economies

The sources of growth in government revenues and expenditures in 22 OECD countries is addressed. The question of whether the revenue constraint is binding on the growth of government expenditures, or whether the ‘displacement’ effect of expenditure growth is binding is considered. Controls for the effects of the output gap and inflation rate on government revenues and expenditures in each of the 22 countries are presented. A major conclusion is that reductions in spending are essential to reducing budget deficits and controlling government size.     

Coordination versus flexibility in wage formation: a focus on the nominal wage impact of productivity in Germany,Greece, Ireland,Portugal, Spain and the United States

Wage coordination between countries of the European Monetary Union (EMU) aims at aligning nominal wage growth with labour productivity growth at the national level. We analyse the developments in Germany, the EMU’s periphery countries Greece, Ireland, Portugal and Spain along with the United States over the period 1980 to 2010. Apart from the contribution of productivity to nominal wages, we take into account the contributions of prices, unemployment, replacement rates and taxes by means of an econometrically estimated nonlinear equation resulting from a wage bargaining model. We further study the downward rigidities of nominal wages. The findings show that in past times of low productivity, price inflation and reductions in unemployment still put significant upward pressure on nominal wage growth. The periphery countries are far from aligning nominal wage growth with productivity growth. German productivity is a major wage determinant, but surely not the only one. Within the context of a free bargaining process between employers and labour unions, policy-makers can effectively use the replacement rate to steer the nominal wages outcome.     

Measuring business cycle comovements in Europe: Evidence from a dynamic factor model with time-varying parameters

Estimation results from a dynamic factor model confirm an increase in output synchronization across European countries during the run-up to the inception of EMU, but EMU by itself has not continued to foster the emergence of a common business cycle.     

Estimating the effect of the EMU on current account balances: A synthetic control approach

The European sovereign debt crisis wrought major political and economic damage on the European Monetary Union (EMU). This led to a reassessment of the pre-crisis period of economic growth and stability in the EMU, shifting attention to the macroeconomic imbalances that emerged between member states, especially those in current account balances. This paper uses macroeconomic data on OECD economies and a new statistical approach for causal inference in observational studies—the synthetic control method—to estimate the effect of the EMU on the current account balances of individual member states. This ‘counterfactuals’ approach provides strong evidence that the introduction of the EMU was responsible for the divergence in current account balances among member states in the run-up to the euro crisis. The results suggest that the EMU effect operated through multiple channels and that fundamental changes to the institutional framework of the EMU may be required to safeguard the currency union against a reemergence of dangerous external imbalances in the future.     

How far from the Euro Area? Measuring convergence of inflation rates in Eastern Europe

We present a common factor framework of convergence which we implement using principal components analysis. We apply this technique to a dataset of monthly inflation rates of EMU and the Eastern European New Member Countries (NMC) over 1996–2007. In the earlier years, the NMC rates moved independently from an average of the three best performing countries over the past twelve months, while they moved somewhat closer in line with them in the later years. Looking at the sample of the EMU and NMC countries as a whole, there is evidence of a formation of convergence clubs across the two groups.     

Low‐inflation Targeting and Long‐run Unemployment*

The model of Akerlof, Dickens and Perry (2000) (ADP) predicts that low inflation may cause unemployment to persist at high levels. When applied to U.S. data, their results strongly rejected the conventional NAIRU model. We apply the ADP model to Swedish data. The fact that our Swedish data also reject the NAIRU model has a number of interesting implications for the Swedish economy and, potentially, for other European countries as well. The results indicate that raising the Swedish inflation target from 2 to 4 percent would bring long‐run unemployment down by several percentage points. The possibility of ADP‐type long‐run Phillips curves also across the euro countries may raise some concern about the EMU project. While detailed studies on other countries are needed, there is nothing to suggest that these non‐vertical Phillips curves would not differ considerably across the euro countries. Any single inflation level targeted by the ECB would then generate excess unemployment in individual member states.     

Long-run impacts of inflation across sectors in a small sample of countries

This article investigates the long-run effects of inflation on economic output for 10 sectors of the economy, with a sample of 7 countries. The analysis is done using long-run restrictions in a vector autoregression and reports long-run multipliers with bootstrapped confidence bands. The results suggest that some sectors seem to be affected differently than others, as well as significant heterogeneity across countries. The results suggest the strongest effects in the low inflation countries Germany and Japan as has been found in similar studies. In contrast to research using growth regressions, the evidence suggests a positive long-run effect of inflation on output.     

The macroeconomic determinants of private equity investment: a European comparison

A strong private equity (PE) market is a cornerstone for commercialization and innovation in modern economies. However, substantial differences exist in the relative amounts raised and invested in PE across European countries. We investigate the macroeconomic determinants of PE investment in Europe, focusing on the comparison between Central and Eastern European (CEE) and Western European countries. Our estimations are based on a data set running from 2001 to 2011 that covers 16 countries. Applying robust estimation techniques, we identify a ‘robust’ set of determinants of PE activity in both regions. We find similarities as well as differences in the driving forces of PE investments in Western European and CEE countries. Our results suggest that economic activity, the inflation rate, equity market capitalization, unit labour costs, the unemployment rate as well the the institutional and legal environment are significant determinants of PE activity.     

Does the Single Currency Affect Foreign Direct Investment?*

Does the creation of the euro partly explain the sharp increase in European investments? To address this question, we derive a simple gravity‐like model for bilateral foreign direct investment (FDI). Using this model, we find that the Economic and Monetary Union (EMU) has increased intra‐EMU FDI stocks on average by around 30 percent. This effect varies over time and across EMU members. It is found to be larger for the outward investments of the less‐developed EMU members. Moreover, contrary to early expectations of FDI diversion effects, EMU countries have invested more in non‐EMU countries since the launch of the euro.     

Multiple Wage Bargaining Systems in the Single European Currency Area

Little attention in the EMU literature has been paid to the interaction between centralbank monetary rules and systems of collective wage bargaining. Analytically andempirically, coordinated wage bargaining systems respond with real wage restraintto non-accommodating monetary policy. Since wage determination is dominated bycollective bargaining in all the EMU member states and wage coordination within themember states has grown since 1980, this is a topic of potential importance. In particular, the replacement of the Bundesbank, directly targeting German inflation, by an ECB targeting European inflation has removed a major institutional support of wage restraint in Germany. The consequences of this for EMU are worked out under two scenarios, that inflation expectations will be generated by ECB monetary policy and that they will reflect German inflation outcomes. Possible institutional developments are discussed including government-union bargains. The Bundesbank has also played a major role in maintaining fiscal rectitude by targeting excess fiscal deficits in Germany: again its replacement by the ECB – targeting (if at all) European rather than German fiscal policy – loosens fiscal constraints. For underlying structural reasons therefore, it is possible that Germany and other EMU countries will move to a period of fiscal activism with wage restraint and low inflation purchased through social contract negotiations.     

Did the euro give us a break in inflation?

The introduction of the euro was accompanied by promises of lower inflation rates; however, the public feels that inflation increased when the euro was introduced. Officials admit that certain sectors experienced substantial price increases, but they claim that the overall inflation rate did not increase. This paper investigates whether inflation in 15 European countries experienced a structural break after the euro was introduced using new powerful and serial correlation robust test statistics. We find evidence that the European Monetary Union (EMU) countries experienced a positive break in inflation after 1999. Our results demonstrate that inflation just after the introduction of the euro was higher relative to the inflation just prior to the introduction of the euro. Additionally, we find no evidence of positive breaks for the non-EMU countries when the euro was introduced.
