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; and lexicographic affine...

We report initial findings from a household survey of Pacific island migrants and their remittances, conducted in 2010-11 in New South Wales (NSW). The study covers three Polynesian communities, Samoans and Tongans as in previous studies, but also Cook Islanders. We cover migrants in both Sydney...

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...

Consider a standard mechanism design setting with quasi-linear preferences and private valuations. From Holmström (1979), we know that if the valuations are smooth with respect to types then any efficient, dominant strategy mechanism is in the class of Groves mechanisms. Here I show that, given...
