Numerous studies have examined the relationship between tourist expenditure and observable characteristics of the individual and the trip. We add latent variables based on psychographic factors into a model of expenditure by nature-based tourists. This study models the log of per person trip expenditure by domestic and international visitors in a Norwegian alpine national park region as a function of psychographic factors as well as traditional measures of trip and demographic characteristics. In the regression models, factor scores were utilized from nature orientation, recreation experience preference (REP), a new ecological paradigm (NEP) and wilderness preference (WPS) scales. Higher scores on a NEP environmentalism factor were associated with higher expenditure, while higher scores This study was funded by the Research Council of Norway, through the project 'Sustainable tourism development in mountain park areas' (186891/110), under the NATURNAER (former AREAL) programme, and co-funded by the Norwegian Farmers' Union (Norges Bondelag) and the National Park Realm (Nasjonalparkriket). We also thank the Norwegian Public Roads Administration, Region East, Gudbrandsdal District, as well as the participating accommodation establishments in Northern Gudbrandsdal, for their kind support in recruiting tourists to the survey. Furthermore, we thank project partners, project reference group members, and stakeholder representatives for their contributions to the survey development. Finally, we thank Eivind Farstad for comments on an earlier draft. All remaining errors and omissions are entirely our own responsibility.
TOURISM ECONOMICS 302on a REP risk seeking factor were associated with lower expenditure. Higher scores on a risk seeking, or challenge factor, from the nature orientation scale was associated with lower expenditure, while higher scores on an inspiration seeking factor were associated with higher expenditure. Structural equation models were then estimated for comparison. The implications for tourism management and marketing are discussed.
