Top responsiveness is introduced by Alcalde and Revilla [Journal of Mathematical Economics 40 (2004) 869-887] as a property which induces a rich domain on playerss preferences in hedonic games, and guarantees the existence of core stable partitions. We strengthen this observation by proving the...

A redistribution system is any social system as organization, company or institution is where the redistribution of payments of players in comparison with their performance happens. The very important role is played by constitutions of alliances created in this system. Modeling of essential...

There are two varieties of timing games in economics: In a war of attrition, more predecessors helps; in a pre-emption game, more predecessors hurts. In this paper, we introduce and explore a spanning class with rank-order payoffs that subsumes both as special cases. In this environment with...

The contribution resumes the article called Nash Equilibrium in Redistribution Systems (Calculation, significance, use), published in the magazine ACTA 1/2008. It is based on some general methodological questions of theory development that use mathematical apparatus, where finding an appropriate...

Fixed point theorems are the standard tool used to prove the existence of equilibria in mathematical economics. This paper shows how to prove a slight generalization of Brouwer's and Kakutani's fixed point theorems using the familiar techniques of drawing and shifting curves in the plane and is,...
