Herd behavior and contagion in Tunisian financial system

This chapter surveys the literature of the contagion effect between financial systemic risk and the contagion of a mimetic behavior during the revolution period. The results proved the contagion effect between Tunisian financial variables and especially the contagion of behavioral investors and banks customers during the revolution period. The results confirm the fragility of the Tunisian financial system towards spillovers effects and the contagion of behavioral investors and banks customers. They must induce Tunisian policy-makers to impose measures such as exposure limits to reduce these effects likelihoods, as part of the macro-prudential approach, to stabilize growth.
