Loss aversion in strategy-proof school-choice mechanisms

Evidence suggests that participants in strategy-proof matching mechanisms play dominated strategies. To explain the data, we introduce expectation-based loss aversion into a school-choice setting and characterize choice-acclimating personal equilibria. We find that non-truthful preference submissions can be strictly optimal if and only if they are top-rank monotone. In equilibrium, inefficiency or justified envy may arise in seemingly stable or efficient mechanisms. Specifically, students who are more loss averse or less confident than their peers obtain suboptimal allocations.

Nori-Motive und Tannaka-Theorie

In the late 90s M. V. Nori constructed a category of motives in charakteristic 0. Using a directed graph with a representation into noetherian R-Modules, he defined a universal R-linear abelian category, called diagram category.The following paper describes this construction and gives proof to the necessary universal property. In addition we establish a criteria for the diagram category to be a category of finitely generated modules over a certain coalgebra. Finally we sketch the connection between the diagram category and the representations of affine group schemes (Tannaka-Dualism) and define the category of mixed Nori-Motives.
