We study procurement procedures that simultaneously determine specification and price of a good. Suppliers can offer and produce the good in either of two possible specifications, both of which are equally good for the buyer. Production costs are interdependent and unknown at the time of...

We study a cardinal model of voting with three alternatives where voters' von Neumann Morgenstern utilities are private information. We consider voting protocols given by two-parameter scoring rules, as introduced by Myerson (2002). For these voting rules, we characterize symmetric Bayes Nash...

Two agents have to choose one of three alternatives. Their ordinal rankings of these alternatives are commonly known among them. The rankings are diametrically opposed to each other. Ex-ante efficiency requires that they reach a compromise, that is choose the alternative which they both rank...

We study dominant strategy implementation in a variant of the canonical public good provision model, as proposed by Borgers and Postl (2009). In this set up, we fully characterize the set of budget-balanced dominant strategy deterministric mechanisms, which are simple threshold rules. For...

We study strategy-proof decision rules in the variants of the canonical public good model proposed by Borgers and Postl (2009). In this setup, we fully characterize the set of budget-balanced strategy-proof deterministic mechanisms, which are simple threshold rules. For smooth probabilistic...

We study procurement procedures that simultaneously determine specification and price of the required good. Two suppliers can each produce the good in any one of two possible specifications, both of which are equally good for the buyer. Production costs are interdependent and unknown at the time...
