“…While on one side tourism literature finds evidences on the positive role of tourism for economic growth, on the other side, it stresses the potential negative effects of a possible overproduction: in attractive locations, tourists and residents compete for the use of natural amenities along with a long list of public and private services, as a result, an unbalanced number of visitors may generate a switch of the virtuous economic cycle into a vicious one via the generation of many types of negative externalities. Shubert (2009, pp.3-4) (Budowski, 1976;Liu, Sheldon and Var, 1987;Dwyer and Forsyth, 1993;Chao, Hazari and Sgro, 2004;Cushman et al 2004;Aguilò et al, 2005;Cerina, 2007) or at the change in the residents attitude towards tourism (Akis et al, 1996;Faulkner and Tideswell, 1997;Johnson, 1997, 1999;Haralambopoulos and Pizam, 1996;Figini et al, 2007). Little attention is given to the possible negative externalities arising from the increase of crime in tourist destinations.…”
