This paper examines the impact of detailed tourism expenditure on the long-run economic growth by employing Autoregressive Distributed Lag (ARDL) approach and causality test for data set of 2003:1 to 2012:4 in Turkey. The detailed tourism expenditure data are firstly employed for the causality of tourism expenditure on economic growth. The results of the bounds test show that there is a stable long-run relationship between accommodation expenses, transport expenditure, expenditure of sporting activities, sightseeing tour expenditure, clothing-footwear expenditure, gift expenditure and economic growth. The results of the causality test, on the other hand, show that there is a bidirectional causality between accommodation expenses, expenditure of sporting activities, gift expenditure and economic growth and a causal flow from transport expenditure to economic growth which is verified growth-led tourism hypothesis. Results reveal that sightseeing tour expenditure and expenditure of sporting activities are more successful on explaining the long-run growth in Turkey in terms of ARDL coefficients size. This result implies a policy that Turkey needs to invest tourism to gain more especially by focusing accommodation, sightseeing tours, sporting activities and transport infrastructure.
