To allow society to treat unequal alternatives distinctly we propose a natural extension of Approval Voting [7] by relaxing the assumption of neutrality. According to this extension, every alternative receives ex-ante a non-negative and finite weight. These weights may differ across...

This paper reports on a laboratory experiment which investigates the impact of institutions and institutional choice in constant-sum sender-receiver games. We compare individual sender and receiver behavior in two different institutions: A sanction-free institution which is given by the bare...

In this paper we show experimentally that in a sequential auction the presence of synergies leads to more overbidding which in turn may result in bankruptcies. In line with theoretical predictions we find that the seller benefits from the buyers’ synergies. In contrast to theory the buyers...

We show in a sender-receiver game with strictly opposing interests that rewards enhance trust but do not influence truth-telling. Subjects who reward tend to tell the truth and trust more often in the presence and absence of reward opportunities. The amount of obtained rewards thereby enhances...

In this paper we show experimentally that in a sequential auction the presence of synergies leads to more overbidding which in turn may result in bankruptcies. In line with theoretical predictions we find that the seller benefits from the buyers’ synergies. In contrast to theory the buyers...

In this paper a selection theory for stochastic games is developed. The theory itself is based on the ideas of Harsanyi and Selton to select equilibria for games in standard form. We introduce several possible definitions for the stochastic tracing procedure, an extension of the linear tracing...

Under a k-approval scoring rule each agent attaches a score of one to his k most preferred alternatives and zero to the other alternatives. The rule assigns the set of alternatives with maximal score. Agents may extend preferences to sets in several ways: they may compare the worst alternatives,...

We introduce trustworthy traders in bilateral trading. Trustworthy traders do not misrepresent their private information. We prove that an increase in the levels of trust (probabilities that traders are trustworthy) can reduce the maximum attainable probability of trade among the strategic...

Coordination failures constitute an alternative explanation for underemployment that complements the Keynesian and neo-classical views. The paper proposes to distinguish three classes of models with coordination failures. The classes are formed by strategic models with or without a coordinating...

Dynamic TU-games are considered which consist of a finite player set, a finite sequence of TU-games and a profile of intertemporal utility functions. At every stage a (restrictively) additive solution is applied to the TU-game, which results in a stream of payoff distributions, evaluated by the...
