When did unsystematic monetary policy have an effect on inflation?

An important stylized fact to emerge from the VAR estimates is that exogenous monetary policy shocks (also labelled unsystematic monetary policy) have a delayed, persistent, hump shaped effect on inflation. I argue that this empirical pattern is fragile. In particular it disappears when one corrects for the effects of large shifts (breaks) in average inflation or examines periods without such shifts (such as the 1984-2004 period). An important consequence is that the hump shaped VAR estimated response of inflation is not appropriate to fit stylised models of the response of inflation around a stable steady state inflation level.

Global inflation

This paper shows that inflation in industrialized countries is largely a global phenomenon. First, inflations of (22) OECD countries have a common factor that alone account for nearly 70% of their variance. This large variance share that is associated to Global Inflation is not only due to the trend components of inflation (up from 1960 to 1980 and down thereafter) but also to fluctuations at business cycle frequencies. Second, Global Inflation is, consistently with standard models of inflation, a function of real developments at short horizons and monetary developments at longer horizons. Third, there is a very robust "error correction mechanism" that brings national inflation rates back to Global Inflation. This model consistently beats the previous benchmarks used to forecast inflation 1 to 8 quarters ahead across samples and ountries.

A VAR description of the effects of monetary policy in the individual countries of the euro area

This paper presents a complete set of results describing the effects of monetary policy in 10 countries of the euro area for the pre-EMU period. For each country, we impose one of three identification schemes depending on its monetary integration with Germany, the nominal anchor of the ERM. The first identification scheme applies to Germany, the second to countries of the core EMS (Austria, Belgium and the Netherlands) and the third to all the other countries. An unexpected rise in the short-term interest rate leads to a decrease in GDP, (with investment and exports falling more than consumption) and a gradual decrease in prices for all countries. We also show that, given the width of the error bands around the estimate, we cannot reject that the effects of monetary policy on GDP and on prices are broadly similar in the individual countries of the euro area JEL Classification: E52Euro area countries, monetary policy, VARs

Forecasting the central bank’s inflation objective is a good rule of thumb

This paper first shows that the forecast error incurred when assuming that future inflation will be equal to the inflation target announced by the central bank is typically at least as small and often smaller than forecast errors of model-based and published inflation forecasts. It then shows that there are substantial benefits in having rule-of-thumb agents who simply trust that the central bank will deliver its pre-announced inflation objective.

Global inflation

This paper shows that inflation in industrialized countries is largely a global phenomenon. First, the inflation rates of 22 OECD countries have a common factor that alone accounts for nearly 70 percent of their variance. This large variance share that is associated with Global Inflation is not only due to the trend components of inflation (up from 1960 to 1980 and down thereafter) but also to fluctuations at business cycle frequencies. Second, we show that, in conformity to the prediction of New Keynesian open economy models, there is little spillover of inflationary shocks across countries. The comovement of inflation comes largely from common shocks. Global Inflation is a function of real developments at short horizons and monetary developments at longer horizons. Third, there is a robust "error correction mechanism" that brings national inflation rates back to Global Inflation. A simple model that accounts for this feature consistently beats the previous benchmarks used to forecast inflation 4 to 8 quarters ahead across samples and countries.Inflation (Finance)

Are inflation targets good inflation forecasts?

The authors show that quantified inflation objectives, which have been adopted by many industrialized countries, can be used as rule-of-thumb forecasting devices. Remarkably, they yield smaller forecast errors than widely used forecasting models and the forecasts of professional experts.Inflation (Finance)

Breaks in the mean of inflation: how they happen and what to do with them

In most OECD countries, we cannot reject up to three breaks in the mean of inflation: one break in the late 1960’s-early 1970’s, one in the early-mid 1980’s and another break in the early 1990’s. These breaks tend to be associated more often to breaks in the mean of nominal variables than to the one of real variables, which reinforces the view that they are monetary phenomena. We also show that ignoring breaks in the mean of inflation clearly lead to overrate inflation persistence in standard bi-variate models of inflation. The response of inflation to shocks in these models is markedly faster with breaks than without breaks. Finally, controlling for breaks in the mean of inflation weakens the effects on inflation of M3 growth and of the real unit labour cost towards insignificance while the effects of the output gaps on inflation are more robust.

Fast micro and slow macro: can aggregation explain the persistence of inflation?

An aggregation exercise is proposed that aims at investigating whether the fast average adjustment of the disaggregate inflation series of the euro area CPI translates into the slow adjustment of euro area aggregate inflation. We first estimate a dynamic factor model for 404 inflation sub-indices of the euro area CPI. This allows to decompose the dynamics of inflation sub-indices in two parts: one due to a commonInflation (Finance) ; Consumer price indexes ; Euro

Investment and monetary policy in the euro area

This paper analyses the effects of a change in monetary policy on firms' investment in Germany, France, Italy and Spain using a data set which provides aggregated balance sheet and profit and loss account data for 17 different industries and 3 different size classes. The main findings are twofold. First, in each of the four countries a change in the user cost of capital, which in turn is affected by interest rates, has both statistically and economically significant effects on investment. Second, while the average interest rate on debt is generally higher for small firms than for large firms, there is little evidence that the effects of monetary policy on small firms are larger JEL Classification: E52
