The objective of this research project is to combine themes from psychology and economics to analyze the incidence of proenvironmental behavior (PEB). Both disciplines share an interest in understanding the influence of internal processes and external conditions on behavior.


Data are analyzed from a mail survey of participants and nonparticipants in a premium-priced, green electricity program. Internal variables are based on general beliefs about the environment and general briefs about the welfare of others. The former are measured with a modified version of the New Ecological Paradigm (NEP) scale; the latter are measured with a newly constructed altruism scale based on the Schwartz norm-activation model. External conditions are represented by a set of sociodemographic variables. Results indicate that the belief variables and certain external conditions are statistically significant predictors of PEB. Additional insight is gained from analysis of individual motivations, or specific beliefs, for participating in the program. In a rank ordering, a biocentric motivation ranks first, an altruistic motivation ranks second, and an egoistic motivation ranks third. These motivations are shown to correlate reasonably with general beliefs, as represented by the NEP scale and the altruism scale.
