The core of a cooperative game on a set of players $N$ is one of the most popular concepts of solution. When cooperation is restricted (feasible coalitions form a subcollection $\cF$ of $2^N$), the core may become unbounded, which makes its usage questionable in practice. Our proposal is to make...

The collective model assumes that decisions taken inside the family are Pareto optimal. However, empirical studies cast doubts upon the efficiency assumption, especially on the production side of household decision making. In this paper, we present a model of household behavior including a...
