When the economy is subject to recurrent structural shifts, the monetary authority cannot credibly commit to a systematic approach to policy, since consistency between promises and actions is not easily verifiable; moreover, since agents have incomplete knowledge of the surrounding environment,...

The applied literature on adaptive learning has mostly focused on small, linear models, with homogenous expectations. In non-linear models heterogeneous expectations prevail and the process through which agents select (and change) a forecasting model becomes a necessary ingredient of the...

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...

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...

The flattening of the Phillips curve observed in the industrial countries has been attributed to globalisation, while the traditional explanation centres on monetary policy credibility. The empirical literature is not conclusive, since macroeconomic data are affected by substantial...

The paper assesses the effects of increasing competition in the service sector in Italy which, based on cross-country comparisons, is the OECD country with the highest markups in non-manufacturing industries. We propose a two-region (Italy and the rest of the euro area) dynamic general...

We assess the short- and medium-term macroeconomic effects of competition-friendly reforms in the service sector when the monetary policy rate is stuck at the zero lower bound (ZLB) in a monetary union. We calibrate a large-scale multi-country multi-sector dynamic general equilibrium model to...

This paper analyses the macroeconomic effects of a protracted period of low and falling inflation rates when monetary policy is constrained by the zero lower bound (ZLB) on nominal interest rates and the private sector is indebted in nominal terms (debt-deflation channel). In this scenario, even...

Price versus productivity indexing is considered in a model of monetary policy with wage bargaining. The wage-indexing rule is negotiated in a first stage of the game between government, union and firm.
