Since 2013 the inflation rate in the euro area has fallen steadily, reaching all-time lows at the end of 2014. Market-based measures of inflation expectations (such as inflation swaps) have also declined to extremely low levels, which suggests increasing concern about the credibility of the ECB...

Unit roots in output, an exponential 2 per cent rate of convergence and no change in the underlying dynamics of output seem to be three stylized facts that cannot go together. This paper extends the Solow-Swan growth model allowing for cross-sectional heterogeneity. In this framework, aggregate...

For a class of long memory volatility models, we establish the asymptotic distribution theory of the Gaussian estimator and the Lagrange multiplier test. Both the case of estimation of martingale difference and ARMA levels are considered. A Montecarlo exercise is presented to assess the small...

Cointegration analysis tests for the existence of a significant long-run equilibrium among some economic variables. Standard econometric procedures to test for cointegration have proven unreliable when the long-run relation among the variables is characterized by non-linearities and persistent...

We explain why the macroeconomic effects of shocks to inflation of the same size, but opposite sign, are not necessarily symmetric. All in all, the costs of deflation and disinflation tend to exceed those of inflation due to the presence of constraints in the economy, namely the zero lower bound...

Global monetary conditions are often cited as a driver of commodity prices. This paper investigates the empirical relationship between US monetary policy and commodity prices by means of a standard VAR system, commonly used in analysing the effects of monetary policy shocks. The results suggest...

We conduct a regional analysis of the relationship between market concentration and price dynamics in the grocery retail sector, focusing on a sample of five categories of goods belonging to the 12 COICOP aggregation and on a panel of countries that includes Germany, Spain, Finland, Italy,...

In the past decade changes in oil prices have played a significant role in shaping inflation dynamics in the US and in the euro area, largely through their direct effect on fuels prices, reviving the controversy over whether the prices of petroleum products respond more promptly to positive than...

This paper investigates the microeconomic behaviour of consumer prices in Italy using the individual price records underlying the Italian CPI dataset collected by Istat. We discuss how to analyse price stickiness using such a detailed database and compute a quantitative measure of the...

This paper provides a detailed insight into the magnitude of price-level differentials among Italian regions, supplementing the data collected by Istat with information on house prices and rentals collected by Agenzia del Territorio and by the Bank of Italy and with estimates from other sources....
