We derive distributional effects for a non-cooperative alternative to the unitary model of household behaviour. We consider the Nash equilibria of a voluntary contributions to public goods game. Our main result is that, in general, the two partners either choose to contribute to di¤erent public...

This paper provides an exhaustive characterization of testability and identifiability issues in the collective framework in the absence of price variation; it thus provides a theoretical underpinning for a number of empirical works that have been developed recently. We first provide a simple and...

The literature on the characterization of aggregate excess and market demand has generated three types of results: global, local, or ’at a point’. In this note, we study the relationship between the last two approaches. We prove that within the class of functions satisfying standard...
