A general revealed preference test for quasilinear preferences: theory and experiments
提出一种适用于非线性预算集和非凸偏好的拟线性偏好显示偏好检验，并通过实验室真实努力任务实验验证了该检验的实证相关性。
Abstract We provide a generalized revealed preference test for quasilinear preferences. The test applies to nonlinear budget sets and non-convex preferences as those found in taxation and nonlinear pricing contexts. We study the prevalence of quasilinear preferences in a laboratory real-effort task experiment with nonlinear wages. The experiment demonstrates the empirical relevance of our test. We find support for either convex (non-separable) preferences or quasilinear preferences but weak support for the hypothesis of both quasilinear and convex preferences.
