This study examines the relationship between tourism demand for Turkey and national income of the tourist generating country at constant prices, and relative prices (prices in the host country divided by prices in tourist generating country). In determining the relationship, a double-logarithmic functional form of the regression model is used. Taking the period 1980-1993 as the base of the study, 18 countries which constitute an important percentage of tourism demand in Turkey have been chosen. In general, the results indicate a positive relationship between tourists arrivals and national income of tourist generating countries, and a negative relationship between tourist arrivals and relative prices. © 1998 Elsevier Science Ltd.
