A Comprehensive Approach to Revealed Preference Theory
扩展了Afriat定理，使其适用于经典消费者理论之外的各种选择环境，如彩票、或有消费和跨期消费，并提供了在这些环境中检验理性化的方法。
We develop a version of Afriat's theorem that is applicable in a variety of choice environments beyond the setting of classical consumer theory. This allows us to devise tests for rationalizability in environments where the set of alternatives is not the positive orthant of a Euclidean space and where the rationalizing utility function is required to satisfy properties appropriate to that environment. We show that our results are applicable, amongst others, to choice data on lotteries, contingent consumption, and intertemporal consumption.
