Questo saggio analizza il NAIRU utilizzando un VAR cointegrato e dati che riferiscono al mercato del lavoro italiano. In questo saggio si mostrerà perché un VAR cointegrato rappresenta un approccio statisticamente adeguato alla stima del NAIRU, cioè un modo efficace di superare i diversi...

We investigate the occurrence of risk sharing among Italian regions with respect to both long run and short run income fluctuations by means of Vector Equilibrium Correction Models (VEqCMs) which allow to test all implications of the theory without preliminary filtering or transformations of...

When observed over a large panel, measures of risk (such as realized volatilities) usually exhibit a secular trend around which individual risks cluster. In this article we propose a vector Multiplicative Error Model achieving a decomposition of each risk measure into a common systematic and an...

Italian Abstract:In questo saggio vengono utilizzati metodi di analisi delle serie storiche al fine di studiare le relazioni tra il rapporto debito pubblico/PIL e le sue determinanti macroeconomiche (quali il rapporto saldo primario/PIL, il PIL reale, il tasso di inflazione e il tasso di...

Italian Abstract: In Italia con il termine Cassa Integrazione Guadagni (CIG) ci si riferisce genericamente agli strumenti di integrazione salariali in costanza di rapporto, che permettono alle imprese di assorbire gli effetti occupazionali di shock inattesi alla domanda preservando la...

Profit share in Italy has been growing between the mid-1970s and the mid-1990s, remaining stable at historically high levels since than. After dropping in the first half of the 1970s, owing to an unprecedented rapid rise in wages, profit share started to recover. The rise during the 1980s...

Financial time series analysis has focused on data related to market trading activity. Next to the modeling of the conditional variance of returns within the GARCH family of models, recent attention has been devoted to other variables: first, and foremost, volatility measured on the basis of...

In this paper we investigate the existence of the economies of scale and density in the Italian water sector, in the period 2005-2007. For this purpose, given the current developments of the reform introduced by the Galli Law, we review the main studies on the cost variables and on the evidence...

We analyze several measures of volatility (realized variance, bipower variation and squared daily returns) as estimators of integrated variance of a continuous time stochastic process for an asset price. We use a Multiplicative Error Model to describe the evolution of each measure as the product...
