Consumption of Values

Consumption decisions are partly influenced by values and ideologies. Consumers care about global warming, child labor, fair trade, etc. We develop an axiomatic model of intrinsic values—those that are carriers of meaning in and of themselves—and argue that they often introduce discontinuities near zero. For example, a vegetarian’s preferences would be discontinuous near zero amount of animal meat. We distinguish intrinsic values from instrumental ones, which are means rather than ends and serve as proxies for intrinsic values. We illustrate the relevance of our value-based model in different contexts, including equity concerns and prosocial behavior.
