How much does quality adjustment matter in measuring consumer price inflation? To address this question, we use different sources of micro and macro price data for Germany and the euro area. For Germany, we find that quality adjustment applies to a large range of goods and services but, on...

This paper asks whether a textbook Phillips curve can explain the behavior of core inflation in the euro area. A critical feature of the analysis is that we measure core inflation with the weighted median of industry inflation rates, which is less volatile than the common measure of inflation...

This paper uses index number theory to disentangle changes in aggregate retail interest rates due to changes in individual component rates ("interest rate effect") from those caused by changes in the weights of each component ("weight effect"), on the basis of the "difference" index numbers...

Using euro-area data, we re-examine the empirical success of New Keynesian Phillips Curves (NKPCs). The nature of our re-evaluation relies on the actual empirical underpinnings of such estimates: we find existing estimates un-robust and u0096 given that key parameters are generally calibrated...

All else equal, higher wages translate into higher inflation. More rigid wages imply a weaker response of inflation to shocks. This view of the wage channel is deeply entrenched in central banks' views and models of their economies. In this paper, we present a model with equilibrium unemployment...

Estimates of the welfare costs of inflation based on Bailey (1956) are typically computed using aggregate money demand models. Yet, the behavior of money demand may vary across sectors. Thus, the impact on welfare of in.action regime shifts may differ between households and firms. We...

This paper studies the role of global factors in causing common movements in consumer price inflation, with particular focus on the food, housing and energy sub-indices. It uses a comprehensive dataset of 223 countries and territories collected from national and international sources. Global...

This paper provides a comprehensive empirical analysis of the role of discretionary fiscal policy for inflation differentials across the 19 euro area countries over the period 1999-2019. The results confirm existing (older) literature that it is difficult to find robust evidence of the fiscal...

This paper studies optimal monetary policy responses in an economy featuring sectorial heterogeneity in the frequency of price adjustments. It shows that a central bank facing heterogeneous nominal rigidities is more likely to behave less aggressively than in a fully sticky economy. Hence, the...

Standard economic models hold that exchange rates are influenced by fundamental variables such as relative money supplies, outputs, inflation rates and interest rates. Nonetheless, it has been well documented that such variables little help predict changes in floating exchange rates u0097 that...
