We consider the problem of distributing the proceeds generated from a joint venture in which the participating agents are hierarchically organized. We characterize a family of allocation rules ranging from the so-called zero-transfer rule (which awards agents in the hierarchy their individually...

We consider a generalization of the Minimum Cost Spanning Tree (MCST) model dubbed the Minimum Cost Connection Network (MCCN) model, where network users have connection demands in the form of a pair of target nodes they want connected directly, or indirectly. Given a network which satisfies all...

In the minimum cost spanning tree model we consider decentralized pricing rules, i.e. rules that cover at least the efficient cost while the price charged to each user only depends upon his own connection costs. We define a canonical pricing rule and provide two axiomatic characterizations....
