This study assesses the economic impact of summer courses organized far away from the headquarters of a Spanish middle-sized university. This academic activity contributes to the revitalization of the tourism in the city with the arrival of new tourists for academic and professional purposes who generate revenues in the city with their consumption. Furthermore, this economic impact is increased by the expenditure undertaken by the organizers themselves to carry out the summer courses (input - output methodology is used). Finally, we conclude that these summer courses play a significant role in revitalizing tourism in the city that hosts the Summer University.
