We introduce a family of sequential contributions rules for minimum cost spanning tree problems. Each member of the family assigns an agent part of the cost of connecting him to his immediate predecessor, and all of his followers are equally responsible for the remaining part. We characterize...

We consider the class of binary social choice problems. A society must choose one of two public projects, money being available to perform side payments and each agent having quasi-linear preferences. Moulin (1987) formulates the problem and characterizes the egalitarian solution on the basis of...

The bankruptcy problem is concerned with how to divide the net worth of the bankrupt firm among its creditors. In this paper, we investigate the logical relations between various axioms in the context of bankruptcy. Those axioms are: population-and-resource monotonicity, consistency, converse...

We present two impossibility results on the converse consistency principle in the context of bargaining. First, we show that there is no solution satis-fying Pareto optimality, contraction independence, and converse consistency. Next, we show that there is no solution satisfying Pareto...

This discussion paper resulted in a publication in 'Social Choice and Welfare', 2012, 38, 519-529.<P> We investigate the implications of imposing balanced consistency and balanced cost reduction in the context of sequencing problems. Balanced consistency requires that the effect on the payoff from...</p>

This discussion paper resulted in a publication in the 'Journal of Economic Theory', 2014, 153, 33-45.<P> Complementary to the axiomatic and mechanism design studies on queueing problems, this paper proposes a strategic bargaining approach to resolve queueing conflicts. Given a situation where...</p>
