We consider the allocation problem of assigning heterogenous objects to a group of agents and determining how much they should pay. Each agent receives at most one object. Agents have non-quasi-linear preferences over bundles, each consisting of an object and a payment. Especially, we focus on...

We conduct laboratory experiments for the Vickrey auction with and without an announcement on strategy-proofness to subjects. Although the rate of truth-telling among the subjects stays at 20% without the announcement, it increases to 47% with the announcement. Moreover, by conducting...

We show that every sequential screening model is equivalent to a standard text book static screening model. We use this result and apply well-established techniques from static screening to obtain solutions for classes of sequential screening models for which standard sequential screening...

A seller is selling multiple objects to a set of agents. Each agent can buy at most one object and his utility over consumption bundles (i.e., (object,transfer) pairs) need not be quasilinear. The seller considers the following desiderata for her mechanism, which she terms desirable: (1)...

This paper studies a model of mechanism design with transfers where agents' preferences need not be quasilinear. In such a model, (1) we characterize dominant strategy incentive compatible mechanisms using a monotonicity property; (2) we establish a revenue uniqueness result: for every dominant...

Crowdfunding challenges the traditional separation between finance and marketing. It creates economic value by reducing demand uncertainty, which enables a better screening of positive NPV projects. Entrepreneurial moral hazard threatens this effect. Using mechanism design, mechanisms are...

In mechanism design with (partially) verifiable information, the revelation principle holds if allocations are modelled as the Cartesian product of outcomes and verifiable information, giving rise to evidence-contingent mechanisms. Consequently, incentive constraints characterize the...

We study ex post information rents in sequential screening models where the agent receives private ex ante and ex post information. The principal has to pay ex post information rents for preventing the agent to coordinate lies about his ex ante and ex post information. When the agent's ex ante...

Who does, and who should initiate costly certification by a third party under asymmetric quality information, the buyer or the seller? Our answer ' the seller ' follows from a non-trivial analysis revealing a clear intuition. Buyer-induced certification acts as an inspection device, whence...

The paper studies procurement contracts with pre-project investigations in the presence of adverse selection and moral hazard. To model the procurer's roblem, we extend a standard sequential screening model to endogenous information acquisition with moral hazard. The optimal contract displays...
