显性偏好是使经济主体观察到的行为合理化的品味。规范性偏好代表代理人的实际利益。有时，假设显性偏好与标准偏好是相同的，这是有意义的。但在许多情况下，这一假设被违反了。我们确定了增加显性偏好和规范性偏好之间差异的可能性的五个因素：被动选择、复杂性、有限的个人经验、第三方营销和跨期选择。然后，我们讨论了六种共同有助于识别规范性偏好的方法：结构估计、主动决策、渐近选择、聚合显性偏好、报告偏好和知情偏好。这些方法中的每一种都使用消费者行为来推断标准偏好的某些性质，而不是将显性偏好和标准偏好等同起来。我们用储蓄和投资结果的证据来说明这些问题。(C)2008爱思唯尔B.V.保留所有权利。
Revealed preferences are tastes that rationalize an economic agent's observed actions. Normative preferences represent the agent's actual interests. It sometimes makes sense to assume that revealed preferences are identical to normative preferences. But there are many cases where this assumption is violated. We identify five factors that increase the likelihood of a disparity between revealed preferences and normative preferences: passive choice, complexity, limited personal experience, third-party marketing, and intertemporal choice. We then discuss six approaches that jointly contribute to the identification of normative preferences: structural estimation, active decisions, asymptotic choice, aggregated revealed preferences, reported preferences, and informed preferences. Each of these approaches uses consumer behavior to infer some property of normative preferences without equating revealed and normative preferences. We illustrate these issues with evidence from savings and investment outcomes. (C) 2008 Elsevier B.V. All rights reserved.
