Neuroökonome Christian Ruff über die biologische Grundlage unseres Entscheidungsverhaltens.
Der Mensch versteht viele Dinge – nur sein eigenes Gehirn kaum. Die Neuroökonomie will herausfinden, wieso wir gewisse Entscheidungen rational und anderer irrational fällen. Sie zeigt Wege auf, wie wir Entscheide optimieren könnten. Werden wir durch solche Erkenntnisse eines Tages zu...

Many postulated relations in finance imply that expected asset returns should monotonically increase in a certain characteristic. To examine the validity of such a claim, one
typically considers a finite number of return categories, ordered according to the underlying characteristic. A standard approach is to simply test for a difference in expected returns between the highest...

Higher-dimensional symmetric games become of more and more importance for applied micro- and macroeconomic research. Standard approaches to uniqueness of equilibria have the drawback that they are restrictive or not easy to evaluate analytically. In this paper I provide some general but comparably simple tools to verify whether a symmetric game has a unique symmetric equilibrium or...

We study the effects of deliberation on collective decisions. In a series of experiments, we vary groups' preference distributions (between common and conflicting interests) and the institutions by which decisions are reached (simple majority, two-thirds majority, and unanimity). Without deliberation, different institutions generate significantly different outcomes, tracking the...
