The contrast between self-interested behavior guided by rational choice and
altruistic behavior guided by normative considerations is a central theme
in the social sciences. This study suggests that market and market-like beh
avior, the context where self-interest is expected to dominate, is in fact
often motivated by altruism. This argument is tested by examining a willing
ness to pay measure, a surrogate for the market that is finding substantial
use in analyses of public policy. In particular, the ability of the Schwar
tz model of altruism to explain willingness to pay for recycled products is
examined. Findings indicate that even as the Schwartz model has explained
many purely altruistic behaviors, it also can explain self-reported willing
ness to pay While economists often have noted the importance of rational ch
oice in even the most intimate of human decisions, this study notes the imp
ortance of normative altruism in even the most calculated.
