We study mechanism design problems in quasi-linear environments where the en- velope theorem and revenue equivalence principle fail due to non-convex and non- differentiable valuations. Despite these obstacles, we obtain a characterization of in- centive compatibility based on the familiar...

We study optimal price discrimination when a monopolist faces a continuum of consumers with reference-dependent preferences. A consumer's valuation for product quality consists of an intrinsic valuation affected by a private state signal (type), and a gain-loss valuation that depends on...

In a setting where agents have quasi-linear utilities over social alternatives and a transferable commodity, we consider three properties that a social choice function may possess: truthful implementation (in dominant strategies); monotonicity in differences; lexicographic affine maximization....

Consider a social choice setting in which agents have quasilinear utilities over monetary transfers. A domain D of admissible valuation functions of an agent is called a revenue monotonicity domain if every 2-cycle monotone allocation rule is truthfully implementable (in dominant strategies) and...
