When Actions Speak Louder Than Prospects
通过新实验检验后悔理论，发现改变问题表述方式会导致人们改变选择，结果支持后悔理论而非传统前景理论。
Many theories of individual choice under risk and uncertainty are formu lated in terms of preferences over prospects, i.e., probability distr ibutions of consequences. By contrast, regret theory is formulated in terms of actions, i.e., n-tuples of state-contingent consequences. W hat appear from the viewpoint of prospect-based theories to be innocu ous rephrasings of choice problems are predicted by regret theory to cause people to reverse their choices. This paper follows up earlier results with a new kind of experimental test. The new evidence favors regret theory. Copyright 1988 by American Economic Association.
