The relationship between our general equilibrium model with multi- member households and club models with multiple private goods is investigated. The main distinction in the definitions consists of the equilibrium concepts. As a rule, competitive equilibria among households where no group of...

We integrate individual power in groups into general equilibrium models with endogenous group formation. We distinguish between formal power (the say in group decisions) and real power (utility gain from being in groups). Their values will be determined as part of the equilibrium. We find that...
