The Shapley value of a cooperative transferable utility game distributes the dividendof each coalition in the game equally among its members. Given exogenous weightsfor all players, the corresponding weighted Shapley value distributes the dividendsproportionally to their weights. In this...

Human decision making is a process guided by different and partly competing mo-tivations that can each dominate behavior and lead to different effects depending on strength and circumstances. “Over-stylizing” neglects such competing concerns and context-dependence, although it facilitates...

I conduct an experiment to assess whether majority voting on a nonbindingsharing norm affects subsequent behavior in a dictator game. Ina baseline treatment, subjects play a one shot dictator game. In a votingtreatment, subjects are first placed behind a ‘veil of ignorance’ and vote onthe...

Economics has devoted little attention so far as to whether the type of decision maker matters for economic decisions. However, many important decisions like those on monetary policy or a company’s business strategy are made by (small) groups rather than an individual. We compare behaviour of...

We test for behavioral differences between groups and individuals in gift-exchange experiments. Related studies establish group behavior as typically closer to the game-theoretic equilibrium. We show that this result my depend crucially on the decision making procedure within groups. A novel...

Many real-life applications of house allocation problems are dynamic. For example, inthe case of on-campus housing for college students, each year freshmen apply to move inand graduating seniors leave. Each student stays on campus for a few years only. A studentis a \newcomer" in the beginning...

The variable threat-bargaining model of Nash (1953) assumes that threats in the senseof binding commitments as to what one will do if bargaining ends in conflict, are chosenbefore bargaining. By comparison, late threats to be chosen after bargaining end in conflict,appear more natural and would...

A unique indivisible commodity with an unknown common value is owned bygroup of individuals and should be allocated to one of them while compensating theothers monetarily. We study the so-called fair division game (Güth, Ivanova-Stenzel,Königstein, and Strobel (2002, 2005)) theoretically and...

Norms play an important role in establishing social order. Thecurrent literature focuses on the emergence, maintenance and impactof norms with regard to coordination and cooperation. However, theissue of norm-related conict deserves more attention. We develop ageneral theory of \normative...

We study ultimatum and dictator experiments where the first moverchooses the amount of money to be distributed between the playerswithin a given interval, knowing that her own share is fixed. Thus, thefirst mover is faced with scarcity, but not with the typical trade-off betweenher own and the...
