This paper explores the use of fuzzy regression-discontinuity design in the context where multiple treatments are applied at the threshold. The identification result shows that, under a very strong assumption of equality of treatment probability changes at the cutoff point, a difference in fuzzy...

Since the middle of the 1980s many European countries have reduced the strictness of their employment protection mainly by relaxing it for temporary jobs. These countries are Belgium, Denmark, Germany, Greece, Italy, the Netherlands, Portugal, Spain and Sweden. The article explores the...

It has been shown that, with an alternative factorization of fuzzy weak preferences into symmetric and antisymmetric components, one can prove a fuzzy analogue of Arrow's Impossibility Theorem even when the transitivity requirements on individual and social preferences are very weak. It is...

This paper studies by means of reciprocal fuzzy binary relations the aggregation of preferences when individuals show their preferences gradually. We have characterized neutral aggregation rules through functions from powers of the unit interval in the unit interval. Furthermore, we have...

We test whether generosity is related to political preferences and partisanship in Canada, Sweden, the United Kingdom and the United States using incentivized dictator games. The total sample consists of more than 5,000 respondents. We document that support for social spending and redistribution...

We study political competition in an environment in which voters have private information about their preferences. Our framework covers models of income taxation, public-goods provision or publicly provided private goods. Politicians are vote-share-maximizers. They can propose any policy that is...
