In this paper, we reexamine the optimal tax problem with identical consumers in the presence of externalities by taking explicitly the interrelationship between externality and consumption into account. In setting out the optimal tax conditions in the presence of externalities, it is standard to...

Since Ray (1987) posed a question of representing nonpaternalistic functions (namely aggregators) in paternalistic form, Bergstrom (1999) identified sufficient conditions for a given list of linear aggregators to possess a unique list of utility functions (over consumption allocations) as the...

In this paper, we consider the budget distribution problems defined by Herrero et al. [1999]. We provide axiomatic characterizations of the rights-weighted solution, introduced by Bergantinos and Mendez-Naya [1999], and pseudo rights-weighted solution both of which are generalizations of the...

In a simple game, coalitions belonging to a given class are "absolutely powerful" while others have no power. We attempt to make this distinction operational. Toward this end, we propose two axioms on social choice correspondences, Strong Non-Discrimination and Exclusion. Strong...

In this paper we consider social preferences over intergenerational consumption paths for a continuum of generations. We prove that equal treatment of all generations is incompatible with Mackey continuity of social preferences under mild axioms such as nontriviality and asymmetry. We also show...

In a simple game, coalitions belonging to a given class are supposed to be "absolutely powerful" while others have no power. We attempt to make this distinction operational. Toward this end, we propose two axioms, Exclusion and Strong Non-Discrimination. Strong Non-Discrimination describes...

In this paper, the model of endogenous fertility proposed by Becker and Barro (1988), and extended by Benhabib and Nishimura (1989) is considered. However, in their model, the uniqueness of the optimal path may fail to hold. Furthermore, the value function may not be concave, because of the...
