We derive several implications of incentive compatibility in general (i.e., not necessarily quasilinear) environments. Building on Kos and Messner (2013), we provide a (partial) characterization of incentive compatible mechanisms.

We characterize the boundaries of the set of transfers (extremal transfers) implementing a given allocation rule without imposing any assumptions on the agentʼs type space or utility function besides quasi-linearity. Exploiting the concept of extremal transfers allows us to obtain an exact...

This paper explores the sale of an object to an ambiguity averse buyer. We show that the seller can increase his profit by using an ambiguous mechanism. That is, the seller can benefit from hiding certain features of the mechanism that he has committed to from the agent. We then characterize the...

This paper considers the optimal mechanism design problem of an expected revenue maximizing principal who wants to sell a single unit of a good to an agent who is ambiguity averse in the sense of Gilboa and Schmeidler (1989). We show that the optimal static mechanism is an ambiguous mechanism....

We characterize the boundaries of the set of transfers implementing a given allocation rule without imposing any assumptions on the agent's type space or utility function besides quasi-linearity. In particular, we characterize the pointwise largest and the pointwise smallest transfer that...

We examine a model of limited communication in which the seller is selling a single good to two potential buyers. Limited communication is modeled as follows: in each of the finite number of periods the seller asks one of the two buyers a binary question. After the final answer, the allocation...

We analyze the value of information in the market for corporate control. The raider and the shareholders are privately and imperfectly informed about the post-takeover value of the firm. We show that public information provision reduces the dispersion of the shareholders’ beliefs resulting in...

We study tender offers for a firm which is owned by one large shareholder who holds less than half of the total shares, and many small shareholders who each hold a unit share. Each shareholder is privately informed, yet uncertain, about the raider’s ability to improve the value of the firm,...
