Mixed rules in multi-issue allocation situations

Multi-issue allocation situations study problems where we have to divide an estate among a group of agents. The claim of each agent is a vector specifying the amount claimed by each agent on each issue. We present a two-stage rule. First we divide the estate among the issues following the constrained equal awards rule. Second, the amount assigned to each issue is divided among the agents proportionally to their demands on this issue. We apply such rule to two real problems: the distribution of natural resources between countries and the distribution of budget for education and research between universities.
