We introduce a variant of the smooth transition autoregression - the GSTAR model - capable to parametrize the asymmetry in the tails of the transition equation by using a particular generalization of the logistic function. A General-to-Specific modelling strategy is discussed in detail, with...

We study Ramsey monetary policy in a New Keynesian (NK) model with endogenous growth and knowledge spillovers external to each firm. We find that in contrast with the standard NK model, the Ramsey dynamics implies deviation from full inflation targeting in response to technology and government...

We study Ramsey monetary policy in a New Keynesian model embodying pollutant emissions and greenhouse gas emissions control policy. We find that the optimal response of inflation to technology shocks is crucially affected by the environmental regime adopted for emissions control.

We study the potential impact of fiscal devaluation policies on the Italian economy using IGEM, a dynamic general equilibrium model for the Italian economy developed at the Department of Treasury of the Italian Ministry of the Economy and Finance. The simulations show that fiscal devaluation...

Recent empirical evidence by Fair (2002, 2005) and Giordani (2003) shows that a positive inflation shock with the nominal interest rate held constant has contractionary effects. These results cannot be reconciled with the standard "New Synthesis" literature. This paper reconsiders the effects of...

This paper analyzes the dynamic properties of the Taylor rule with the zero lower bound on the nominal interest rate in an optimizing monetary model with overlapping generations. The main result is that the presence of wealth effects is not sufficient to rule out the possibility of infinite...

This paper examines the dynamics of the nominal exchange rate and fiscal deficits in a continuous time optimizing general equilibrium model with finite horizon. It is shown that alternative financing modes of budget deficits imply different patterns of adjustment along the transitional path...

This paper presents a dynamic stochastic general equilibrium model with nominal rigidities, capital accumulation and finite horizons. Our New Keynesian framework exhibits intergenerational wealth effects and is intended to investigate the macroeconomic implications of fiscal policy, which is...

Since the second half of 2011, after a period of prolonged low growth, Italy has found itself at the center of a severe economic crisis. Concerns about the sustainability of its debt burden, along with gloomy growth prospects, have pushed up the cost of government borrowing, exacerbating current...

We study the implications of having different sources of nominal rigidities on the relationship between productivity growth and shocks volatility in a model with procyclical R&D and imperfect competition in goods and labour markets. We show that the effects of uncertainty on long-term growth not...
