Abstract
In this paper, we discuss the consequences of taking inot account the variations of the natural real interest rate (rt*) in simple monetary policy rules. We also provide one possible model-based analysis of the level of rt* that has prevailed in the euro area since the early 1970s, and present the implied 'real rate rate gap' as a possible additional indicator to assess the stance of monetary policy.

Abstract
This paper investigates a dynamic general equilibrium model with search. In particular, search externalities are reflected by an increasing return to scale matching function, which may imply an indeterminate equilibrium. Hence, the model is capable to generate business fluctuations, driven by self-fulfilling belief, characterised by unemployment persistence. A numerical simulation shows that the degree of externalities needed for indeterminacy is not too far from existing empirical estimates and the implied dynamics of employment is richer than that of standard RBC models with search.

Abstract
This paper presents a two period overlapping generations model with endogenous growth in the presence of a public sector with objectives of convergence for public debt and primary balance to GDP ratios. In order to ensure the existence of converging paths towards the target values of fiscal variables, we introduce a simple fiscal policy rule. According to this rule, the primary balance ratio is adjusted in function of the distance between the current and the target levels of the public debt and the primary surplus to GDP ratios. It is shown that the fiscal rule displaying time invariant parameters may produce non linear dynamic processes of adjustment of the fiscal ratios as well as endogenous fluctuations in the rate of growth of the economy. In addition the transitional process towards fiscal targets critically depends on the adjustment tool chosen by the fiscal authorities to implement the rule.

Abstract
This paper develops a dynamic stochastic general equilibrium model with nominal rigidities, capital accumulation and finite lifetimes. The framework exhibits intergenerational wealth effects and is intended to investigate the macroeconomic implications of fiscal policy, which is specified by either a debt-based tax rule or a balanced-budget rule allowing for temporary deficits. When calibrated to euro area quarterly data, the model predicts that fiscal expansions generate a tradeoff in output dynamics between short-term gains and medium-term losses. It is also shown that the effects of fiscal shocks crucially depend upon the conduct of monetary policy. Simulation analysis suggests that balanced-budget requirements enhance the determinacy properties of feedback interest rate rules by guaranteeing inflation stabilization.

Abstract
This paper presents a survey of methods for assessing fiscal soundness, i.e. the capability of governments to honour their obligations in the short run and in the long run. The need for a comprehensive monitoring of fiscal soundness derives from the risks to economic stability that arise from the actual or expected difficulty a government may have in honouring its obligations. For the long run, methods derived from the government's intertemporal budget constraint make it possible to assess the size of a necessary adjustment to achieve sustainability of the debt burden. Uncertainty regarding shocks to the fiscal situation or the behaviour of financial market participants calls for the monitoring of financial flows and government obligations in the short run. Vigilance needs to be all the higher, the greater the uncertainty regarding long-term sustainability.

In this paper we address the question on whether EMU has amplified or dampened intra euro area divergencies, by looking at a time-varying VAR model of Italy
