Many economists are libertarians and consider the term "paternalistic" to be derogatory. Most would think that the phrase libertarian paternalism is an oxymoron. The modest goal of this essay is to encourage economists to rethink their views on paternalism. We believe that the anti-paternalistic fervor expressed by many economists is based on a combination of a false assumption and at least two misconceptions. The false assumption is that people always (usually?) make choices that are in their best interest. This claim is either tautological, and therefore uninteresting, or testable. We claim that it is testable and false-indeed, obviously false.
The first misconception is that there are viable alternatives to paternalism. In many situations, some organization or agent must make a choice that will affect the choices of some other people. The point applies to both private and public actors. Consider the problem facing the director of a company cafeteria who discovers that the order in which food is arranged influences the choices people make. To simplify, consider three alternative strategies: (1) she could make choices that she thinks would make the customers best off; (2) she could make choices at random; or (3) she could maliciously choose those items that she thinks would make the customers as obese as possible. Option 1 appears to be paternalistic, which it is, but would anyone advocate options 2 or 3?
The second misconception is that paternalism always involves coercion. As the cafeteria example illustrates, the choice of which order to present food items does not coerce anyone to do anything, yet one might prefer some orders to others on paternalistic grounds. Would many object to putting the fruit before the desserts at an elementary school cafeteria if the outcome were to increase the consumption ratio of apples to Twinkies? Is this question fundamentally different if the customers are adults? If no coercion is involved, we think that some types of paternalism should be acceptable to even the most ardent libertarian. We call such actions libertarian paternalism.
In our understanding, a policy counts as "paternalistic" if it is selected with the goal of influencing the choices of affected parties in a way that will make those parties better off. We intend "better off to be measured as objectively as...
