Constant improvement of computing facilities creates a trend to build always larger macroeconomic models. To master these huge and complex models, much effort must be spent to investigate their functioning, mostly by means of simulations or perturbations of their original structure. Such...

Climate change affects hydropower production by modifying total annual inflow volumes and their seasonal distribution. Moreover, increasing air temperatures impact electricity consumption and, as a consequence, electricity prices. All together, these phenomena may lead to a loss in revenue. We...

A computationally efficient branch-and-bound strategy for finding the subsets of the most statistically significant variables of a vector autoregressive (VAR) model from a given search subspace is proposed. Specifically, the candidate submodels are obtained by deleting columns from the...
