The aim of this study is to investigate differences in willingness to pay more for sustainable hotels, analyzing whether consumers’ searches for information about sustainability, the importance they assign to sustainability certifications, their previous experiences and sociodemographic variables, are all features that influence consumer intentions. We thus contribute to the literature on the importance of consumers’ concerns and awareness and how they influence consumer intentions regarding sustainability in the hotel sector. Our results, based on a sample of consumers of various nationalities, show that all the variables analyzed can explain the differences between consumers that are willing to pay more for sustainable hotels and those that are not, except those variables capturing sociodemographic characteristics. These results could help hotel managers to establish strategies to retain more responsible consumers and increase awareness of sustainability, and should prompt them to improve their sustainability practices.

This study analyzes how consumers' evaluations of various dimensions of corporate social responsibility (CSR) affect their support of it and how consumers' searches for CSR information influence such evaluations. The empirical analysis relies on data on CSR from a wide representative sample of 3543 Spanish hotel consumers. We use hierarchical multiple regressions to test the relationships and use factorial analysis to test the validity of the different CSR dimensions. The proposed positive effects of legal, ethical, economic, philanthropic and environmental dimensions of CSR on consumers' support for corporate reputation, the selection of an establishment, and future purchase intention are corroborated, although they are only partially corroborated in the case of the economic dimension. These relationships are moderated in some cases by consumers' search for information about hotels' CSR practices. Managerial and economic implications are derived from the results.
