This paper uses the autoregressive distributed lag (ARDL) approach to cointegration to estimate the coefficients of the determinants of international tourism demand for Zimbabwe for the period 1998 to 2005.The results show that taste formation, transport costs, changes in global income and certain specific event have a significant impact on international tourism demand.
