Resumen de Empirical analysis of market behaviour: a mesoscopic approach
With this doctoral dissertation, we aim to contribute to the literature in two different ways. On the one hand, using an agent based model, we provide policymakers and investors with new methods that can be used in financial markets to assess their stability, describe their dynamics, and forecast their future performance. On the other hand, we analyse the evolution of the cross-sectional distribution of activity in the real economy to better understand the firms' destiny. The main results of our two first chapters show that models based on the social interactions provide investors with useful information to set trading strategies, while the last chapter of this thesis demonstrates that the firms' destiny can be tracked by means of the analysis of their profit and growth rate cross-sectional distribution over time.
