We study the effects of institutional constraints on stability and efficiency in the “one-way flow” model of network formation. In this model the information that flows through a link between two players runs only towards the player that initiates and supports the link, so in order for it to...

This paper provides a new model of network formation that bridges the gap between the two benchmark game-theoretic models by Bala and Goyal (2000a) – the one-way flow model, and the two-way flow model – and includes both as limiting cases. As in both the said models, a link can be initiated...

In this article, we vindicate the relevance of the notion of success or satisfaction for the normative assessment of voting rules. We provide arguments in support of this view and emphasize the conceptual and analytical differences between this notion and that of decisiveness. The conclusions...

Committees are often made up of representatives, each of them acting on behalf of a group of individuals or constituency of different size, who make decisions by means of a voting rule which specifies what vote configurations in the committee can pass a decision. This raises the question of the...

We study the effects of linking constraints on stability, efficiency and network formation. An exogenous “link-constraining system” specifies the admissible links. It is assumed that each player may initiate links only with players within a specified set of players, thus restricting the...

In this paper we propose a simple model for measuring ‘success’ or ‘decisiveness’ in voting situations. For an assessment of these features two inputs are claimed to be necessary: the voting rule and the voters’ behavior. The voting rule specifies when a proposal is to be accepted or...
