Assuming the time series of random returns to be jointly elliptical, we derive a relationship between its conditional variance and the probability density function of the conditioning set. In the case that such a relationship is linear in a quadratic form for of the conditioning variables, we...

This paper summarizes the proceedings of a conference at the Bank of Greece on credit risk. The papers presented focused on innovations in risk management methods which contribute to systemic financial stability, calculation of capital adequacy in financial institutions as well as the validation...

We investigate the nature of the inflation bias in a model that exhibits asymmetries in preferences and non–normality in shocks but simplifies to the classic Barro-Gordon problem as a special case. The inflation bias is shown to depend on the trade-off between preference, structural and...

This paper examines the exchange rate disconnect puzzle of Obstfeld and Rogoff (2000) from a behavioural perspective. It provides evidence on the existence of substantial asymmetries in the underlying loss preferences for the difference between the spot and forward nominal exchange rates between...
