Regarding inflation as being a monetary phenomenon in the long-run is a widely-held view in modern macro economics. We analyse this topic by means of a P-star model. Based on the quantity theory of money, this approach explains inflation via a supposed equilibrium price level (P-star), which...

This paper carries out another evaluation on a highly debated property of inflation dynamics, namely its persistence. We study inflation dynamics for the United States since 1959 with a time-varying methodology where the intercept, variance and persistence are allowed to vary over time. We...

A key application of long memory time series models concerns inflation. Long memory implies that shocks have a long-lasting effect. It may however be that empirical evidence for long memory is caused by neglecting one or more level shifts. Since such level shifts are not unlikely for inflation,...

By estimating a staggered price model over the period 1980q1-2010q2, this paper documents that, after the Euro changeover, Italian retailers have increased the number of price adjustments, which has translated into a higher inflation rate, with a detrimental effect on the competitiveness of the...

The objective of this paper is to estimate the agricultural output gap for Greece during the period 1858-1938 using the univariate approach. To investigate the unit root hypothesis we use the Lumsdaine & Papell methodology. We show that models containing the agricultural output gap, as measured...

We sketch a framework for monitoring macroeconomic activity in real-time and push it in new directions. In particular, we focus not only on real activity, which has received most attention to date, but also on inflation and its interaction with real activity. As for the recent recession, we find...
