This paper proposes a conceptual framework for the analysis of reward sharing schemes in mining pools, such as those associated with Bitcoin. The framework is centered around the reported shares in a pool instead of agents and introduces two new fairness criteria: absolute and relative...

In river systems, costly upstream pollution abatement creates downstream welfare gains. Without a central authority to enforce such abatement, the welfare gains can only be realized if downstream regions compensate for the upstream abatement. We develop a model that makes explicit the impact of...

We consider a connection networks model. Every agent has a demand in the form of pairs of locations she wants connected, and a willingness to pay for connectivity. A planner aims at implementing a welfare maximizing network and allocating the resulting cost, but information is asymmetric: agents...
