We study a multi-dimensional collective decision under incomplete information. Agents have Euclidean preferences and vote by simple majority on each issue (dimension), yielding the coordinate-wise median. Judicious rotations of the orthogonal axes -- the issues that are voted upon -- lead to...

We assess the strength of the different conditions identified in the literature of robust mechanism design. We focus on three conditions: ex post incentive compatibility, robust monotonicity, and robust measurability. Ex post incentive compatibility has been shown to be necessary for any concept...

A mechanism is unsafe if a small number of agents deviating unexpectedly can make the mechanism deliver an outcome regarded as bad by a large number of other agents. Under Nash behavior, the direct approach of designing mechanisms with only safe Nash equilibria is impossible in many...

We consider school choice problems (Abdulkadiroglu and Sönmez, 2003) where students are assigned to public schools through a centralized assignment mechanism. We study the family of so-called rank-priority mechanisms, each of which is induced by an order of rank-priority pairs. Following the...

Despite the truthful dominant strategy, participants in strategy-proof me- chanisms submit manipulated preferences. In our model, participants dislike rejections and enjoy the confirmation from getting what they declared most desirable. Formally, the payoff from a match decreases in its position...

We study decision rules for committees that repeatedly take a binary decision. Committee members are privately informed about their payoffs and monetary transfers are not feasible. In static environments, the only strategy-proof mechanisms are voting rules which are criticized for being...

This paper considers the problem faced by a political authority that has to design a legislative mechanism that guarantees the selection of policies that are stable, efficient, and inclusive in the sense of strategically protecting minority interests. Experimental studies suggest that some of...

Given the background of changing institutional competencies in the European Union, we analyze the choice of asylum law standards of national and European parliaments, the Council of the European Union and codecision between the Council and the European Parliament. In a two country model we nd...
