Non-linearities in euro area inflation persistence

This paper investigates the nature of inflation dynamics with a special focus on inflation persistence. Using data from euro area member-states we estimate dynamic non-linear panel models addressing in detail econometric issues concerning unobserved heterogeneity, genuine state dependence, and the initial conditions problem. After controlling for observed and unobserved heterogeneity, our results suggest that the degree of inflation persistence is genuine and varies depending on whether the inflation rate is too high, within the range of ECB's target of price stability, too low or negative. This implies that policies to stabilize inflation in the short run will have longer-run effects.     

Inflation and inflation uncertainty in the euro area

This article estimates a time-varying AR-GARCH model of inflation producing measures of inflation uncertainty for the euro area, and investigates their linkages in a VAR framework, also allowing for the possible impact of the policy regime change associated with the start of EMU in 1999. The main findings are as follows. Steady-state inflation and inflation uncertainty have declined steadily since the inception of EMU, whilst short-run uncertainty has stabilised. A sequential dummy procedure provides further evidence of a structural break coinciding with the introduction of the euro and resulting in lower long-run uncertainty. It also appears that the direction of causality has been reversed, and that in the euro period the Friedman-Ball link is empirically supported, consistently with the idea that the ECB can achieve lower inflation uncertainty by lowering the inflation rate.     

A composite leading indicator of the inflation cycle for the Euro area

We evaluate the performance of composite leading indicators of turning points of inflation in the Euro area, constructed by combining the techniques of Fourier analysis and Kalman filters with the National Bureau of Economic Research methodology. In addition, the study compares the empirical performance of Euro Simple Sum and Divisia monetary aggregates and provides a tentative answer to the issue of whether or not the UK should join the Euro area. Our findings suggest that, first, the cyclical pattern of the different composite leading indicators very closely reflect that of the inflation cycle for the Euro area; second, the empirical performance of the Euro Divisia is better than its Simple Sum counterpart and third, the UK is better out of the Euro area.     

Interpreting euro area inflation at high and low frequencies

Several authors have recently interpreted the European Central Bank's (ECB's) two-pillar framework as separate approaches to forecast and analyse inflation at different time horizons or frequency bands. The ECB has publicly supported this understanding of the framework. This paper presents further evidence on the behaviour of euro area inflation using band spectrum regressions, which allow for a natural definition of the short and long run in terms of specific frequency bands, and causality tests in the frequency domain. The main finding is that variations in inflation are well explained by low-frequency movements of money and real output growth and high-frequency fluctuations of the output gap.     

Perceived inflation and the euro: Evidence from an Austrian survey

This paper employs an Austrian micro-dataset to analyze why inflation perceptions became disconnected from official inflation measures in the course of the euro cash changeover. We find evidence that persons who are more often confronted with prices, who expected price increases and who mentally convert euro prices into old currency prices when making price comparisons have a significantly higher perception of inflation. Furthermore, our results indicate that the latter two factors have a persistent impact. This contributes in explaining why price perceptions have not normalized for several years in some countries. The results suggest that policy measures in countries which are going to introduce the euro should address these issues in order to prevent a similar development as experienced in many euro area countries.     

The enlargement of the euro area: differences in relative inflation

This paper investigates the structural determinants of relative inflation (i.e. the inflation of non‐tradables vs tradables) in the context of overall inflation differentials in the EU. The analysis is based on the Bergstrand theoretical model. This framework incorporates three alternative hypotheses of relative inflation (Harrod–Balassa–Samuelson, relative factors endowment, and demand effects). Due to the lack of reliable data on capital stocks only a curtailed version of the model is tested here empirically. The various specifications of the model are estimated for the majority of EU countries, using the Pedroni panel group mean FMOLS estimator. In general, relative labour productivity and demand factors turn out to be significant and correctly signed, though evidence in favour of the latter effect seems to be less robust. In addition, differences in the determination of relative prices between the new and old EU Member States are found. They seem to be consistent with theoretical considerations and the transition phenomenon. The estimation results are very sensitive to the definition of non‐tradables. The paper also discusses policy implications for overall inflation, stemming from relative price models. It questions the usefulness of relative inflation models for the analysis of overall inflation differentials and practical policy decisions.     

The information content of money in forecasting euro area inflation

This article contributes to the debate on the role of money in monetary policy by analysing the information content of money in forecasting euro-area inflation. We compare the predictive performance within and among various classes of structural and empirical models in a consistent framework using Bayesian and other estimation techniques. We find that money contains relevant information for inflation in some model classes. Money-based New Keynesian Dynamic Stochastic General Equilibrium (DSGE) models and Vector Autoregressions (VARs) incorporating money perform better than their cashless counterparts. But there are also indications that the contribution of money has its limits. The marginal contribution of money to forecasting accuracy is often small, money adds little to dynamic factor models, and it worsens forecasting accuracy of partial equilibrium models. Finally, nonmonetary models dominate monetary models in an all-out horserace.     

Measures of underlying inflation in the euro area: assessment and role for informing monetary policy

The paper evaluates the 24-month-ahead inflation forecasting performance of various indicators of underlying inflation and structural models. Measures derived using the generalized dynamic factor model (GDFM) overperform other measures over the monetary policy horizon and are leading indicators of headline inflation. Trimmed means, although weaker than GDFM indicators, have good forecasting performance, while indicators by permanent exclusion underperform but provide useful information about short-term dynamics. The forecasting performance of theoretically-founded models that relate monetary aggregates, the output gap, and inflation improves with the time horizon but generally falls short of that of the GDFM. A composite measure of underlying inflation, derived by averaging the statistical indicators and the model-based estimates, improves forecast accuracy by eliminating bias and offers valuable insight about the distribution of risks.     

A simple analytical model of the adverse real effects of inflation

Abstract

The essential insight advanced in this paper is that the claim that inflation can impair growth makes most sense in the context of a monetary production economy, wherein a role for money in the determination of real activity is posited from the very start. We construct a model of inflation and growth that distinguishes between the properties of various qualitatively different inflation regimes. It is then shown how some of these regimes, by undermining confidence in various nominal contracts that are central to the process of accumulation in a monetary production economy, can adversely affect growth.     

Panel data modelling and the tax-spend controversy in the euro zone

This article attempts to differentiate between the debatable tax and spend, spend and tax, fiscal synchronization and institutional separation hypotheses in order to explore empirically the interplay between public expenditures and public revenues in the Economic and Monetary Union (EMU) member states. For this purpose, panel data models are derived to test the validity of the four hypotheses in EMU countries. A notable characteristic of this article is that the four hypotheses are tested by dividing EMU countries into various subgroups and using disaggregated data for government expenditures and revenues. Seeking for the robustness of the empirical evidence, the panel data methods of Generalized Two-Stage Least Squares (GTSLS) and Generalized Method of Moments (GMM) are accordingly applied to identify the relationship between public outlays and taxation receipts. GTSLS and GMM results strongly support the fiscal synchronization hypothesis implying that budget decision-making is significantly influenced by both government expenditures and revenues components.     

The information content of the divisia monetary aggregates in forecasting inflation in the euro area

The paper investigates the performance of a set of monetary indicators, based on the Divisia money constructed for the euro area, on forecasting euro area inflation. The paper first briefly discusses on the relative information contents of the Divisia aggregates and the simple sum aggregates. The forecasting performance of the former is then examined by means of simulated out-of-sample forecasting. In addition to examining the information contents of the Divisia aggregate constructed for M3 money, the study also examines the performance of the Divisia M1 money to gain evidence on the relative performance between the broad and narrow Divisia monetary aggregates. According to the results, only some of the monetary indicators considered can significantly improve the univariate inflation forecasts. The Divisia M3 money based monetary indicators turned out to perform better than their Divisia M1 based counterparts. The result contradicts some previous evidence on the optimal level on monetary aggregation in the context of broad versus narrow money.      

The effect of a Chinese slowdown on inflation in the euro area and the United States

We investigate the effect of a Chinese slowdown on inflation in the euro area and the United States using the NiGEM multi-country model. We construct different scenarios including a fall in Chinese aggregate demand, a commodity price slump, financial market corrections and a devaluation of the renmimbi. While the commodity slump has the strongest impact on inflation, the demand and exchange rate shocks also play a role; on the contrary, financial turbulences have minor effects. Finally, we study the extent to which monetary policy in advanced economies can succeed in reflating the economy following such a Chinese slowdown. The room for central bank interventions is large.     

Anchoring of inflation expectations in the euro area: Recent evidence based on survey data

This article analyses the anchoring of inflation expectations of professional forecasters and consumers in the euro area. We study anchoring, defined as the central bank's ability to manage expectations, by paying special attention to the impact of the ECB inflation target and ECB inflation projections on inflation expectations. Our analysis indicates that in the post-crisis period longer-term inflation expectations have become somewhat more sensitive to shorter-term ones and to actual HICP inflation. We also find that the ECB inflation projections have recently become more important for short- and medium-term expectations of professional forecasters and at the same time the role of the ECB inflation target for those expectations has diminished. Overall, our analysis suggests that in recent years inflation expectations in the euro area have shown some signs of de-anchoring.     

The impact of oil price changes on Spanish and euro area consumer price inflation

This paper assesses the impact of oil price changes on Spanish and euro area consumer price inflation. We find that the inflationary effect of oil price changes in both economies is limited, even though crude oil price fluctuations are a major driver of inflation variability. The impact on Spanish inflation is found to be somewhat higher than in the euro area. In both economies, direct effects have increased in the last decade, reflecting the higher expenditure share of households on refined oil products, whereas indirect and second-round effects seem to be losing importance.     

A system approach for measuring the euro area NAIRU

This paper addresses the issue of measuring the NAIRU for the euro area and assessing the robustness and precision of the obtained estimates. The empirical framework adopted is based on systems combining an Okun-type relationship between cyclical unemployment and the output gap with a Phillips curve and stochastic laws of motion for the NAIRU and potential output. Such systems have been estimated using Kalman-filter techniques. The results obtained point to an estimate of the area-wide NAIRU that is robust to changes in the underlying models. This robustness is shown to hold both in terms of the mean – i.e., the shape of the resulting NAIRU – and the variance of the process. The latter is derived through bootstrap exercises using the models alone or pooled together. The evidence found suggests that the increase in the aggregate NAIRU that took place in the early part of the sample period has come to a halt and may be about to be reversed.Jel classification: C11, C15, E31, E32The opinions expressed in this paper are those of the authors and do not necessarily reflect the views of the Institutions they belong to.

Asymmetric behavior of inflation differentials in the euro area: Evidence from a threshold unit root test

This paper tests the existence of persistent inflation rate differentials in the euro area by employing linear as well nonlinear unit root tests. Besides linear unit root tests, a two-regime threshold unit root test examines the conjecture that inflation rate differentials follow a nonlinear two-regime process towards a threshold, switching from the persistent regime to the transitory one and vice versa. The results imply that threshold nonlinearity is confirmed in 10 out of the 16 cases. However, we have found unit root regime-switching behavior only in six out of the 16 cases under investigation. This finding implies that these inflation rate differentials were persistent when they were low (regime 1), but transitory when they were high (regime 2). This asymmetric behavior can possibly be explained by the different degree of pressure exercised on governments, which is accompanied with different inflation rate differentials. On the contrary, despite the evidence of nonlinearity, the majority of the inflation rate differentials are found to be monotonically persistent. Our results have strong implications for policy makers. In particular, the documented persistency in the inflation rate differentials might have long-run costs in terms of price and macroeconomic stability.     

On a simple rule for the optimal inflation rate in second best taxation

The optimal inflation rate is analyzed in the framework of dynamic second best with endogenous factor prices. It is shown that when the marginal excess burden of taxation is relatively small, the optimal inflation rate is approximated by a simple rule. The paper also analyzes the robustness of this rule to the specification of the model (money as an input in utility or production).     

An alternative demand indicator: the 'non-accelerating inflation rate of capacity utilization'

This article examines the usefulness of the NAIRCU, the ‘non-accelerating inflation rate of capacity utilization’ as a demand indicator of inflation for eight European countries. So far the NAIRCU has been estimated for the USA only, where it serves as a useful indicator for inflation. In most European countries, deviations from the equilibrium level of capacity utilization influence inflation significantly. Further, the results not only indicate that in more recent periods the NAIRCU has shifted upward, indicating higher efficiency of the production process, but also that confidence intervals have increased over time reducing the usefulness of the NAIRCU somewhat.     

A two-pillar DSGE monetary policy model for the euro area

The current financial crisis has revived the interest for monitoring both monetary and credit developments. Over the past two decades, consistent with the adoption of inflation targeting strategies by a growing number of central banks and the development of New Keynesian models for which monetary aggregates are largely irrelevant, money and credit have been progressively neglected in the conduct of monetary policy. A striking exception has been the Eurosystem, which has implemented a strategy known as the “two-pillar monetary policy strategy” giving a prominent role for money. In this paper, we develop a small optimizing model based on Ireland (2004), estimated on euro area data and featuring this two-pillar strategy. We evaluate an ECB-style cross-checking policy rule in a DSGE model with real balance effects of money. We find some evidence that indeed money plays a non-trivial role in explaining the euro area business cycle. This provides a rationale for the central bank to factor in monetary developments but also raises some issues regarding the reliability of M3 as an appropriate monetary indicator. We find some evidence that the ECB has systematically reacted to a filtered measure of money growth but weak evidence it has reacted more aggressively during excess money growth periods.
