The volume collects the essays presented at the 15th Workshop on Public Finance organised by Banca d'Italia in Perugia from 4 to 6 April 2013. The workshop focused on the link between fiscal policy and macroeconomic imbalances and comprised four sessions. The first session concentrated on the...

For historical and geographical reasons, the member countries of the European Monetary Union (EMU) display different degrees of external trade openness. The paper lays out a model for a currency area composed of two regions. One region is more open to trade with a third country outside the area...

In the monetary policy literature it is commonly assumed that trend inflation is zero, despite overwhelming evidence that zero inflation is neither empirically relevant nor a practical objective for central bank policy. We therefore extend the standard New Keynesian model to allow for positive...

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 briefly reviews the literature on fiscal multipliers and then presents results for the Italian economy obtained by simulating a dynamic general equilibrium model that allows for the possibility (a) that the zero lower bound may be binding and (b) that the initial public debt-to-GDP...

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...

This paper provides new evidence on the transmission of monetary policy in the euro area, assessing the impact of an unexpected increase of the short-term interest rates on the lending and borrowing activity in different economic sectors. We exploit the information content of the flow-of-funds...

In this paper we consider several time-varying volatility and/or heavy-tailed models to explain the dynamics of return time series and to fit the volatility smile for exchange-traded options where the underlying is the main �Borsa Italiana� stock index. Given observed prices for the...

Most of the important models in finance rest on the assumption that randomness is explained through a normal random variable because, in general, the use of alternative models is obstructed by the difficulty of calibrating and simulating them. In this paper, we empirically study models for...

The European Emissions Trading Scheme (ETS) is a cap and trade system to curb CO2 emissions. It has caused both direct costs (CO2 allowances) and indirect costs (higher electricity prices) to energy-intensive industries. Moreover, as there is no global CO2 agreement, the ETS could distort the...
