It is widely recognized that a rapid increase in foreign direct investment leads to an increase in tourism at different levels. This paper applied a Granger Causality test to investigate the causal relationship between International Tourist Arrivals (ITA) and Foreign Direct Investment (FDI) across countries. By using time series data from six countries in the top ten European destinations (France, Spain, Italy, Germany, Turkey, and the United Kingdom) for the 1980-2014 period, the findings reveal that there is a unidirectional causality between ITA and FDI. The results are strongly proven with the same results when the lag between FDI and ITA is lengthened at lag 1. Moreover, the outcome evidence has a unidirectional relationship running from FDI to ITA when GDP is added as the controlling variable.
