Mass tourism, no doubt, has great economic, social, and cultural effects, both positive and negative, on developing and developed nations. While the economic effects of tourism occur on a macro level, such as foreign trade, current account deficit, tourism income, and supply capacity, the social effects of tourism occur on a micro level, producing more indirect benefits in social welfare. In this study, we evaluate the social and economic effects in the development of mass tourism in Turkey from the 1950s to today. Our findings show that there are more economic and social benefits than the disadvantages of mass tourism in Turkey.
