The rationalizability of a choice function by means of a transitive relation has been analyzed thoroughly in the literature. However, not much seems to be known when transitivity is weakened to quasi-transitivity or acyclicity. We describe the logical relationship between the different notions...

We consider the problem of provisioon and cost-sharing of multiple public goods. The efficient equal factor equivalent allocation rule makes every agent indifferent between what he receives and the opportunity of choosing the bundle of public goods subject to the constraint of paying r times its...

We provide a characterization of selection correspondences in two-person exchange economies that can be core rationalized in the sens that there exists a preference profil with some standard properties that generates the observed choices as the set core elements of the economy for any given...

We ask how the three known mechanisms for solving cost sharing problems with homogeneous cost functions - the value, the proportional, and the serial mechanisms - should be extended to arbitrary problem. We propose the Ordinality axiom, which requires that cost shares be invariante under all...

We analyze an alternative to the standard rationalizability requirement for observed choice bu considering non-deteriorating selections.

we identify conditions under which preferences over sets of construction opportunities can be reduced to preferences over bundles of "commodities".

A group of agents located along a river have quasi-liner preferences over water and money. We ask how water should be allocated and what money transfers should be performed.
