In this paper, three models are presented to  capture five different effects of the Libyan crisis on the Tunisian economy: i) the impact of the presence of Libyans in Tunisia on aggregate demand; ii) the effect of the crisis on remittances of Tunisian workers in Libya; iii) the impact of the deteriorating business environment on private investments; iv) the consequences of domestic and regional security challenges on the tourism sector and v) the impact of the crisis on government security spending. The results of simulations present the macroeconomic and fiscal impacts of the Libyan crisis on Tunisia.
