World economies, and especially European ones, have become strongly interconnected in the last decade and a joint modelling is required. We propose here the use of copulae to build flexible multivariate distributions, since they allow for a rich dependence structure and more flexible marginal...

Copula-GARCH models have been recently proposed in the financial literature as a statistical tool to build flexible multivariate distributions. Our extensive simulation studies investigate the small sample properties of these models and examine how misspecification in the marginals may affect...

This paper examines different multivariate models to evaluate what are the main determinants when doing VaR forecasts for a portfolio of assets. To achieve this goal, we unify past multivariate models by using a general copula framework and we propose many new extensions. We differentiate the...

The increase of oil and natural gas prices since the year 2000 stimulated the planning and construction of new coal-fired electricity generating plants and coal-to-liquids plants in the US. However, a large number of these projects have been canceled or abandoned since 2007. Using a set of 145...

In this paper we present some contingent claim analysis’ models for the firm value. We focus on two different approaches: the structural (Merton) approach and a new one that treats the asset value as a claim on the firm’s securities. The non-observability of the assets’...

The aim is to introduce a new econometric methodology for multi-output production frontiers. In the context of a system of frontier equations, a flexible multivariate distribution for the inefficiency error term is used. This multivariate distribution is constructed through a copula function...

We analyze rehabilitation investments in a regulated water industry with perfectly inelastic demand. We compare alternative organizational solutions for local provision (municipalization, corporatization and privatization), though subject to a common regulatory mechanism. We can then assess the...
