Dietary Bounds and Unshackled Demand Specifications
扩展了显示偏好公理的非参数检验，使其适用于面临多重约束的消费者，并用修改后的检验拒绝了仅依赖价格和支出的肉类需求规范，而包含脂肪感知和约束的规范则未被拒绝。
Abstract Conventional tests of revealed preference axioms (WARP and GARP) may yield false rejections of the hypothesis of a unique preference ordering when consumers face constraints in addition to a budget constraint. In this paper, nonparametric tests of WARP and GARP are generalized for consumers who enforce multiple constraints. In conjunction with conventional tests, the modified tests are used to reject meat demand specifications that are functions solely of price and expenditure variables. Richer specifications that include consumer perceptions of the fat content of meats and the fat constraint value in addition to conventional price and expenditure variables cannot be rejected.
