This paper provides sufficient conditions for the existence of pure strategy Nash equilibrium in a class of games of group formation. The use of potential allows for a characterisation of such an equilibrium.

We consider a capital accumulation game between two different jurisdictions. When the jurisdictions adopt open loop strategies, we study the inefficiency of the steady state Nash equilibrium with respect to the steady state utilitarian solution.

We investigate the conditions under which an inequality averse and additively separable welfarist constitution maker would always choose to set up a progressive equalization payment scheme in a federation with local public goods. A progressive equalization payment scheme is defined as a list of...

In a model where agents have unequal skills and heterogeneous preferences about consumption goods and leisure, this paper studies how to combine linear commodity taxes and non-linear income tax. It proposes a particular social welfare function on the basis of fairness principles. It then derives...

We propose the concept of a universal social ordering, defined on the set of pairs of an allocation and a preference profile of any finite population. It is meant to unify evaluations and comparisons of social states with populations of possibly different sizes with various characteristics. The...

We study the possibility of making social evaluations independently of individual preferences over non-consumed commodities. This is related to the well-known problem of performing international comparisons of standard of living across countries with different consumption goods. We prove...
