This study suggests that the framework of dynamic patronage coalitions, based on Roker's coalition theory and workings patron-client networks, ran fruitfully be utilized in analyzing African politics, particularly light increasing prevalence state-society approaches need for a comparative referent. The narrowing helps explain frequency coups, secession attempts, exile invasions first decade or ...

Production costs in general, and workforce and inventory costs in particular, constitute a large fraction of the operating costs of many manufacturing plants. We introduce cooperative aggregate production planning as a way to decrease these costs. That is, when production planning of two or more facilities (plants) is integrated, they can interchange workforce and products inventory; thus, thei...

Large projects often have several activities which are performed by some subcontractors with several skills. Costs and time reduction and quality improvement of the project are very important for client and subcontractors. Therefore, in real large projects, subcontractors join together and form coalitions for improving the project profit. A key question is how an extra profit of cooperation amo...

We study a game-theoretic model where political parties can form coalitions both before and after the elections. Before election, coalitions can commit to a seat-sharing arrangement, but not to a policy or to a division of rents from o¢ ce; coalition members are free to break up and join other coalitions after the election. Equilibrium pre-electoral coalitions are not necessarily made up of the...

When an agent decides whether to join a coalition or not, she must consider both i) the expected strength of the coalition and ii) her position in the vertical structure within the coalition. We establish that there exists a positive relationship between the degree of inequality in remuneration across ranks within coalitions and the number of coalitions to be formed. When coalition size is unre...

This paper examines the endogenous formation of coalitions that provide public goods in which players implement a minimum participation requirement before deciding whether to join. We demonstrate theoretically that payoff-maximizing players will vote to implement efficient participation requirements and these coalitions will form. However, we also demonstrate that if some players are averse to ...

Hedonic games are coalition formation games where players only specify preferences over coalitions they are part of. We introduce and systematically study local fairness notions in hedonic games by suitably adapting fairness notions from fair division. In particular, we introduce three notions that assign to each player a threshold coalition that only depends on the player’s individual preferen...
