Selfishness, Altruism, and Rationality: A Theory of Social Choice

Why do we volunteer time? Why do we contribute money? Why, even, do we vote, if the effect of a single vote is negligible? Rationality-based microeconomic models are hard-pressed to explain such social behavior, but Howard Margolis proposes a solution. He suggests that within each person there are two selves, one selfish and the other group-oriented, and that the individual follows a Darwinian rule for allocating resources between those two selves.

"Howard Margolis's intriguing ideas . . . provide an alternative to the crude models of rational choice that have dominated economics and political science for too long."—Times Literary Supplement

Howard Margolis is a professor in the Harris Graduate School of Public Policy Studies and in the College at the University of Chicago. He is the author of Selfishness, Altruism, and Rationality and Patterns, Thinking, and Cognition, both published by the University of Chicago Press.
