Many indicators (OECD 1994) show that the Italian labour market is characterised by a strong pro-workers and pro-unions legislation. This is usually interpreted as a high degree of rigidity. It is known that, in response to shocks, firms in rigid labour markets tend to trade workers adjustment...

This paper analyses the effect of consumption taxes on unemployment in presence of wage rigidity and compares non-cooperative tax setting under the destination and origin principle of commodity taxation. We show that, in a two country economy, consumption taxes negatively affect domestic...

Hedging strategies for commodity prices largely rely on dynamic models to compute optimal hedge ratios. This paper illustrates the importance of considering the commodity inventory effect (effect by which the commodity price volatility increases more after a positive shock than after a negative...

This paper illustrates some computationally efficient estimation procedures for the estimation of vast dimensional realized covariance models. In particular, we derive a Composite Maximum Likelihood (CML) estimator for the parameters of a Conditionally Autoregressive Wishart (CAW) model...

Several models have been developed to capture the dynamics of the conditional correlations between time series of financial returns, but few studies have investigated the determinants of the correlation dynamics. A common opinion is that the market volatility is a major determinant of the...

Chapter written for the Handbook of Volatility Models and their Applications, edited by Luc Bauwens, Christian Hafner, and Sébastien Laurent, forthcoming in 2012 (John Wiley & sons). This chapter presents an introductory review of volatility models and some applications. The review is linked...

This paper investigates the meaning of systemic risk in energy markets and proposes a methodology to measure it. Energy Systemic Risk is defined by the risk of an energy crisis raising the prices of all energy commodities with negative consequences for the real economy. Measures of the total...
