We propose a new dynamic model for volatility and dependence in high dimensions, that allows for departuresfrom the normal distribution, both in the marginals and in the dependence. The dependence is modeled with adynamic canonical vine copula, which can be decomposed into a cascade of bivariate...

In order to capture observed asymmetric dependence in international financial returns, we construct a multivariate regime-switching model of copulas. We model dependence with one Gaussian and one canonical vine copula regime. Canonical vines are constructed from bivariate conditional copulas and...

In this paper, we present a model of endogenous vertical integration and horizontal differentiation. Thereexists two output brands and two versions of the input. The only mean for output differentiation is the inputversion used in output production. Firms may choose to vertically integrate to...

In a setting of R&D co-opetition we study, by using an all-pay auction approach, howcollaboration affects strategic decisions during a patent contest, and how the latter influences thepossible collaboration network structures the firms can hope to form. The all pay auctionapproach allows us to...
