Computability of simple games: A complete investigation of the sixty-four possibilities

Kumabe, Masahiro; Mihara, H. Reiju - Volkswirtschaftliche Fakultät, … - 2006

Classify simple games into sixteen "types" in terms of the four conventional axioms: monotonicity, properness, strongness, and nonweakness. Further classify them into sixty-four classes in terms of finiteness (existence of a finite carrier) and computability. For each such class, we either show...

A Theory of Rational Attitude Polarization

Benoît, Jean-Pierre; Dubra, Juan - Volkswirtschaftliche Fakultät, … - 2014

Numerous experiments have demonstrated the possibility of attitude polarization. For instance, Lord, Ross & Lepper (1979) partitioned subjects into two groups, according to whether or not they believed the death penalty had a deterrent effect, and presented them with a set of studies on the...

Additive representation of separable preferences over infinite products

Pivato, Marcus - Volkswirtschaftliche Fakultät, … - 2011

Let X be a set of states, and let I be an infinite indexing set. Our first main result states that any separable, permutation-invariant preference order () on X^I admits an additive representation. That is: there exists a linearly ordered abelian group A and a `utility function' u:X--A such...

An optimal bound to access the core in TU-games

Béal, Sylvain; Rémila, Eric; Solal, Philippe - Volkswirtschaftliche Fakultät, … - 2012

For any transferable utility game in coalitional form with a nonempty core, we show that that the number of blocks … required to switch from an imputation out of the core to an imputation in the core is at most n-1, where n is the number of … players. This bound exploits the geometry of the core and is optimal. It considerably improves the upper bounds found so far …
