We examine a decision-theoretic Bayesian framework for the estimation of Sharpe Style portfolio weights of the MSCI sector returns. Following van Dijk and Kloek (1980) an appropriately defined prior density of style weights can incorporate non-negativity and other constraints. We use...

We present a new, full multivariate framework for modelling the evolution of conditional correlation between financial asset returns. Our approach assumes that a vector of asset returns is shocked by a vector innovation process the covariance matrix of which is timedependent. We then employ an...

Credit risk transition probabilities between aggregate portfolio classes constitute a very useful tool when individual transition data are not available. Jones (2005) estimates Markovian Credit Transition Matrices using an adjusted least squares method. Given the arguments of Judge and Takayama...

In this paper we examine the theoretical conditions under which a firm will have incentives to optimallychoose investment projects of duration that deviates from its stated horizon objective. Our approachconsiders a context in which investment horizon is subject to randomness and its length is...

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...

In this paper we examine the relationship of optimal forecasts in two different contexts, that is asymmetric preferences and hubris. The former incorporates preference restrictions directly into the shape of the loss function, whilst the latter does so indirectly by constraining the shape of the...

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...
