ALTHOUGH THE STUDY IS UNABLE TO EMPIRICALLY SEPARATE THE PROPORTION OF ADDITIONAL CRIME THAT IS DIRECTED EXCLUSIVELY AGAINST FOREIGN VISITORS FROM THAT WHICH IS IN SOME WAY PRECIPITATED BY THE INFLUX OF TOURISTS BUT WHICH EVENTUALLY VICTIMIZES MEXICAN SOCIETY IN GENERAL, IT WOULD SEEM REASONABLE TO ASSUME THAT MANY MEXICAN NATIONALS, EVEN IF THEY ARE NOT AFFECTED DIRECTLY, OBTAIN DISUTILITY FROM THE INCREASED CRIME ASSOCIATED WITH TOURISM. THUS, CRIMINAL ACTIVITY CAN REASONABLY BE CONSIDERED AN EXTERNALITY OF THE TOURISM INDUSTRY IN MEXICO. (AUTHOR ABSTRACT)
