This paper is concerned with the minimal number of profiles at which a unanimous and anonymous social choice function is manipulable. The lower bound is derived when there are three alternatives to choose from. Examples of social choice functions attaining the lower bound are given. We...

This paper proposes an assignment model where sorting occurs on attributes that are simultaneously a skill (Sattinger, 1979) and a preference (Tinbergen, 1956). The key feature of this model is that the wage function admits both jobs'' and workers'' attributes as arguments. Since this function...

We compare the manipulability of different choice rules by considering the number of manipulable profiles. We establish the minimal number of such profiles for tops-only, anonymous, and surjective choice rules, and show that this number is attained by unanimity rules with status quo.

The ability to process new information and to compute conditional probabilities is crucial for making appropriate decisions under uncertainty. In this paper, we investigate the capability of inferring conditional probabilities in a representative sample of the German population. Our results show...

A population''s level of terrorism depends on two factors: people''s preferences (would they like creating damage?) and the constraints under which people act (what damage could they create, and at what punishment?). Cause-related policies, e.g. improving social stability or education, aim at...

We extend the domain of preferences to include menu-dependent preferences and characterize the maximal subset of this domain in which the revelation principle holds. Minimax-regret preference is shown to be outside this subset.

This paper analyzes the effect of retirement on cognitive functioning using two large scale surveys. On the one hand the HRS, a longitudinal survey among individuals aged 50+ living in the United States, allows us to control for individual heterogeneity and endogeneity of the retirement decision...

We present an efficiency wage model in which workers'' effort depends on the level and on the growth rate of their wage relative to an alternative wage. Using data for four countries (US, UK, FR, GY), the implications of the model are examined and are found to be in accordance with the...

We consider general two-sided matching markets, so-called matching with contracts markets as introduced by Hatfield and Milgrom (2005), and analyze (Maskin) monotonic and Nash implementable solutions. We show that for matching with contracts markets the stable correspondence is monotonic and...

Dynamic exchange economies with uncertainty are considered in which information is released over infinite time. The strong sequential core of such an economy consists of those consumption processes where no coalition of agents wishes to deviate at any moment for the rest of time. Comparable to...
