    Reducing rent seeking by providing wide public service

    Get PDF
    A winning coalition which sets policy cannot always ensure that members of the coalition will be the ones getting benefits. Different jurisdictions (including members of the winning coalition) may then engage in costly rent seeking. Maximizing the welfare of the winning coalition may therefore require providing services to jurisdictions which are not members of the winning coalition, thereby reducing rent seeking by members of the winning coalition. The paper shows how this mechanism can generate insuffcient supply of public services, and offers another explanation for the use of co-funding requirements by the central government.

    Stable Coalition Structures in Simple Games with Veto Control

    Get PDF
    In this paper we study hedonic coalition formation games in which players' preferences over coalitions are induced by a semi-value of a monotonic simple game with veto control.We consider partitions of the player set in which the winning coalition contains the union of all minimal winning coalitions, and show that each of these partitions belongs to the strict core of the hedonic game. Exactly such coalition structures constitute the strict core when the simple game is symmetric.Provided that the veto player set is not a winning coalition in a symmetric simple game, then the partition containing the grand coalition is the unique strictly core stable coalition structure.Banzhaf value;hedonic game;semi-value;Shapley value;simple game;strict core

    A note on the paradox of smaller coalitions

    Get PDF
    We consider hedonic coalition formation games that are induced by a simple TU-game and a cooperative solution. For such models, Shenoy's (1979) absence of the paradox of smaller coalitions provides a sufficient condition for core existence. We present three different versions of his condition in order to compare it to the top coalition property of Banerjee et al. (2001) that guarantees nonemptiness of the core in more general models. As it turns out, the top coalition property implies a condition in which Shenoy's paradox is not present for at least one minimal winning coalition. Conversely, if for each non-null player Shenoy's paradox is not present for at least one minimal winning coalition containing that player, then the induced hedonic game satisfies the top coalition property.coalition formation, core, paradox of smaller coalitions, simple games, top coalition property

    Agenda Control in Coalition Formation

    Get PDF
    Theoretical models of government formation in political science usually assume that the head of state is non-strategic. In this paper, we analyze the power of an agenda setter who chooses the order in which players are recognized to form coalitions in simple games. We characterize those sets of players which can be imposed in the equilibrium coalition and show that the only decisive structures where the agenda setter can impose the presence of any minimal winning coalition are apex games, where a large player forms a winning coalition with any of the small players.Agenda Control; Cabinet Formation; Simple Games

    Population Monotonic Path Schemes for Simple Games

    Get PDF
    A path scheme for a simple game is composed of a path, i.e., a sequence of coalitions that is formed during the coalition formation process and a scheme, i.e., a payoff vector for each coalition in the path.A path scheme is called population monotonic if a player's payoff does not decrease as the path coalition grows.In this study, we focus on Shapley path schemes of simple games in which for every path coalition the Shapley value of the associated subgame provides the allocation at hand.We show that a simple game allows for population monotonic Shapley path schemes if and only if the game is balanced.Moreover, the Shapley path scheme of a specific path is population monotonic if and only if the first winning coalition that is formed along the path contains every minimal winning coalition.Extensions of these results to other probabilistic values are discussed.cooperative games;simple games;population monotonic path schemes;coalition formation;probabilistic values

    A Bargaining Set Based on External and Internal Stability and Endogenous Coalition Formation

    Get PDF
    A new bargaining set based on notions of both internal and external stability is developed in the context of endogenous coalition formation.It allows to make an explicit distinction between within-group and outsidegroup deviation options.This type of distinction is not present in current bargaining sets.For the class of weighted majority games, the outcomes in the bargaining set containing a minimal winning coalition are characterized.Furthermore, it is shown that the bargaining set of any homogeneous weighted majority game contains an outcome for which the underlying coalition structure consists of a minimal winning coalition and its complement.The paper also introduces a new class of games called cooperation externalities games.For a symmetric cooperation externalities game conditions are provided such that every outcome in the bargaining set supports the same coalition structure.This coalition structure consists of one coalition of all players with an externality parameter higher than one and a collection of singleton coalitions, one for every player with a cooperation externality parameter lower than oneBargaining set;endogenous colation;formation;internal and external stability

    Government versus opposition: Who should be who in the 16th German Bundestag?

    Get PDF
    We model the process of coalition formation in the 16th German Bundestag as a hedonic coalition formation game. In order to induce players' preferences in the game we apply the Shapley value of the simple game describing all winning coalitions in the Bundestag. Using different stability notions for hedonic games we prove that the "most" stable government is formed by the Union Parties together with the Social Democratic Party.coalition formation, Shapley value, simple games, winning coalitions
