Determinants of Intra-firm Diffusion Process of ICT: Theoretical Sources and Empirical Evidence from Catalan Firms

Youssef, Adel Ben; Merino, David Castillo; Hadhri, Walid - HAL - 2012

The analysis of the main determinants of intra-firm diffusion of digital technologies is becoming in the focus of attention. However, there is a lack of empirical research, particularly in Europe. This paper proposes a specific approach to modelling intra-firm diffusion process by combining the...

Modeling Multivariate Interest Rates using Time-Varying Copulas and Reducible Stochastic Differential Equations

Bu, Ruijun; Giet, Ludovic; Hadri, Kaddour; Lubrano, Michel - HAL - 2009

We propose a new approach for modeling non-linear multivariate interest rate processes based on time-varying copulas and reducible stochastic differential equations (SDEs). In the modeling of the marginal processes, we consider a class of non-linear SDEs that are reducible to Ornstein-Uhlenbeck...
