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...

We consider an extension of minimum cost spanning tree (mcst) problems in which some agents do not need to be connected to the source, but might reduce the cost of others to do so. Even if the cost usually cannot be computed in polynomial time, we extend the characterization of the Kar solution...

The Boruvka's algorithm, which computes the minimum cost spanning tree, is used to define a rule to share the cost among the nodes (agents). We show that this rule coincides with the folk solution, a very well-known rule of this literature.

Market integration is seen as a complementary measure to decarbonize energy markets. In the context of power markets, this translates into regions that coordinate to maximize welfare in the power market with respect to a climate target. Yet, the maximization of overall welfare through...

Gómez-Rúa (2011, SERIEÂ’s) considers a river divided into n segments. In each segment there is exactly one agent, who releases some kind of residue into the water. An environmental authority must share the total cost of cleaning the river network among all the agents. In this paper we...
