This paper studies whether the raise in concentration experienced by the Spanish banking sector has lead to the increase of bank-specific credit supply shocks contribution to aggregate credit supply. We decompose aggregate credit volatility and find that (i) the Spanish banking sector is...

The aim of our contribution relies on studying the possibility of implementing a genetic algorithm in order to reproduce some characteristics of a simple laboratory experiment with human subjects. The novelty of our paper regards the estimation of the key-parameters of the algorithm, and the...

We propose a nonparametric method to determine the functional form of the noise density in discrete-time stochastic volatility models of financial returns. Our approach suggests that the assumption of Gaussian noise is often adequate, but we do observe deviations from Gaussian noise for some...
