The following methodology allows us to analysis the dynamic of Tunisian tourism in both short-term and long-term. Our main results show that the real exchange rate is an important factor explaining long-term overnight stays. A currency depreciation of 10% will increase the number of nights spent by visitors by 12% in the long term, but will have the opposite effect in the short term. However, we show that tourism demand is inelastic to income, indicating the low-cost nature of Tunisian tourism.
