SUMMARY
Social responsibility derives from citizens’ concern for environmental damage caused by corporations. In Peru, research on Corporate Social Responsibility (CSR) is incipient, especially that related with hotel companies. This study objective is to determine how CSR influences the purchasing behavior of Tacna city hotel guests. We identified both hotel guests valuation and the variables that influenced their purchase decision. To collect information we used interviews, panel of experts, and questionnaires sent out to hotel companies and hotel guests. We found that there is a relationship between hotels’ CRS practices and consumers’ behavior in its economic, ethical, and philanthropic dimension.
