In classic game theory, agents use mixed strategies in the form of objective and probabilistically precise devices to conceal their actions. We introduce the larger set of probabilistically imprecise devices as strategies and study the consequences for the basic results of normal form games....

This paper presents a class of finite n x n bimatrix (2-player) games we coin Circulant Games. In Circulant Games, each player's payoff matrix is a circulant matrix, i.e.\ each row vector is rotated one element relative to the preceding row vector. We show that when the payoffs in the first row...

We study the problem of assigning indivisible goods to individuals where each is to receive one object. To guarantee fairness in the absence of monetary compensation, we consider random assignments and analyse various equity criteria for such lotteries. In particular, we find that sd-no-envy (as...

This paper examines how neutral the current EU decision-making procedures are to membership and how well they obey certain transparent general constitutional principles. The paper evaluates the performance of the procedures by strategic and classical power indices. The main emphasis in the...

The Winner s Curse (WC) is a non-equilibrium behavior in common-value auctions involving systematic and persistent overbidding that often results in significant losses. It is one of the most robust findings in laboratory experiments. We developed an auction mechanism with a payment rule that...

Dual-process theories view decisions as the result of the interaction of two qualitatively different types of processes, automatic/impulsive and controlled/deliberative. This paper considers a model of self-control where each decision can be taken by either an automatic process or a deliberative...

The paper deals with the competitive effects of price guarantees in a spatial duopoly where consumers can search for lower prices but have to incur hassle costs if they want to claim a price guarantee. It is shown that symmetric equilibria with and without price guarantees exist but price...

We investigate dynamic coordination among members of a problem-solving team who receive private signals about which of their actions are required for a (static) coordinated solution and who have repeated opportunities to explore different action combinations. In this environment ordinal...

Using non-cooperative game theory the effects of mediation on the divorce rate and on the utility of the spouses are analysed. Two kinds of mediation are considered: restricted mediation that reduces the costs of divorce and extended mediation that additionally may prevent divorces by...

We consider a co-evolutionary model of social coordination and network formation where agents may decide on an action in a 2x2 - coordination game and on whom to establish costly links to. We find that a payoff dominant convention is selected for a wider parameter range when agents may only...
