The Bali Roadmap marks a milestone in the process of international consensus building, setting forth a multilateral legal framework to address climate change. Delegates at the UN Climate Change Conference in Bali (Dec. 3-15 2007) launched a two-year process with a comprehensive agenda and 2009...

We examine a chain of sequential losses: an agent causes a loss to another, which triggers a loss to a third, and so forth. Our objective is to redistribute the losses fairly, taking into account that the chain turns "victim" to "injurer" in its subsequent step. This opens up for many...

The present paper examines the stability of self-enforcing International Environmental Agreements (IEAs) among heterogeneous countries in a twostage emission game. In the first stage each country decides whether or not to join the agreement, while in the second stage the quantity of emissions is...

When losses caused by one agent onto another triggers losses to a third, "victim" turns into "injurer" in the chain's subsequent steps. Should agents be responsible for the direct loss they cause or also bear some of the indirect losses they trigger? Through an axiomatic approach, we...

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...

This note presents numerical simulations computing quota rules that maximize collective surplus for populations choosing a one-dimensional policy through bargaining and voting. These computations are based on the characterization of the unique (asymptotic) equilibrium of Cardona and Ponsatí...

Two main school choice mechanisms have attracted the attention in the literature: Boston and deferred acceptance (DA). The question arises on the ex-ante welfare implications when the game is played by participants that vary in terms of their strategic sophistication. Abdulkadiroglu, Che and...

Many procedures have been suggested for the venerable problem of dividing a set of indivisible items between two players. We propose a new algorithm (AL), related to one proposed by Brams and Taylor (BT), which requires only that the players strictly rank items from best to worst. Unlike BT, in...

The paper analyzes quantity competition in economies in which a network describes the set of feasible trades. A model is presented in which the identity of buyers, of sellers, and of intermediaries is endogenously determined by the trade flows in the economy. The analysis first considers small...
