However, most models of banking panics and regulation have not been empirically tested. The Argentine 2001 crisis, with a large deposit withdrawal and the regulation introduced (suspension of convertibility) constitutes a scenario in order to apply some of the theoretical predictions. In particular, the paper applies Samartín (2002) to the particular case of Argentina. After the estimation of the most important parameters, the model predicts that suspension of convertibility seems to have been the most efficient intervention measure to stop the massive deposit withdrawals.[+][-]
