A new analysis of the effects of the Asian crisis of 1997 on emergent markets

Mariani, M.C.; Liu, Y. - In: Physica A: Statistical Mechanics and its Applications 380 (2007) C, pp. 307-316

This work is devoted to the study of the Asian crisis of 1997, and its consequences on emerging markets. We have done so by means of a phase transition model. We have analyzed the crashes on leading indices of Hong Kong (HSI), Turkey (XU100), Mexico (MMX), Brazil (BOVESPA) and Argentina...

Stochastic analysis of an agent-based model

Veglio, A.; Marsili, M. - In: Physica A: Statistical Mechanics and its Applications 385 (2007) 2, pp. 631-636

We analyze the dynamics of a forecasting game that exhibits the phenomenon of information cascades. Each agent aims at correctly predicting a binary variable and he/she can either look for independent information or herd on the choice of others. We show that dynamics can be analytically...

Quasi-static properties of Markovian systems in metastable state: Fluctuation–dissipation theorem

Báez, G.; Méndez-Sánchez, R.A. - In: Physica A: Statistical Mechanics and its Applications 379 (2007) 2, pp. 357-371

We show detailed calculations to obtain a metastable fluctuation–dissipation theorem (FDT) for Markovian systems with detailed balance. This is done by taking, for the metastable probability distribution, a superposition of the ground and the first excited state of the corresponding master...
