This paper investigates the consequences of non-stationarity for the principal components analysis and suggests a data transformation that allows obtaining smoother series for the first principal component to be used as a core inflation indicator. The paper also introduces a theoretical model,...

This paper analyses the results of a survey conducted by the Banco de Portugal between May and September 2004 on a sample of 1370 Portuguese firms with the main purpose of investigating their price setting behaviour. The evidence points to the presence of a considerable degree of price...

We derive principles of optimal short run monetary policy in a real business cycles model, with money and with monopolistic firms that set prices one period in advance. The only distortionary policy instruments are the nominal interest rates and the money supplies. In this environment it is...

This paper assesses the relevance of the exchange rate regime for stabilization policy. This regime question cannot be dealt with independently of other institutions, in particular how .fiscal policy is designed. We show that once .fiscal policy is taken into account, the exchange rate regime is...

Spatial price comparisons rely to a high degree on the quality of the underlying price data that are collected within or across countries. Below the basic heading level, these price data often exhibit large gaps. Therefore, stochastic index number methods like the CPDmethod and the GEKS method...

In Germany, package holidays are an important driver of consumer prices. Several challenges arise when measuring the price development of these bundled travel and accommodation services, such as the quality of accommodation and the timing of booking. Statistical practices are currently based on...

The compilation of commercial property price indices is a big challenge. In Germany, substantive data gaps prevent the calculation of official figures by the national statistical authority. By contrast, policymakers urge for timely, reliable and comprehensive data. In this paper, proposals are...

I propose a new term structure model for euro area real and nominal interest rates which explicitly incorporates a time-varying lower bound for nominal interest rates. Results suggest that the lower bound is of importance in structural analyses implying time-varying impulse responses of yield...

This paper documents a strong relationship between households' perceptions about inflation over the past 12 months and households' short- and long-term expectations about future inflation. This relationship is strong during periods of high-inflation but even stronger during low-inflation...

In this paper we analyze how consumers in Germany updated expectations about inflation in response to the COVID-19 outbreak. We use a fixed effects model to estimate the effect of regional exposure to COVID-19 cases, the stringency of restriction measures and local unemployment rates on...
