We consider efficiency measurement methods in the presence of uncertain input and output data, and without the (empirically problematic) assumption of convexity of the production technology. In particular, we perform a simulation study in order to contrast two well-established methods, IDEA and...

It can be argued that the competitiveness of an industry consists of two main parts: The production conditions and the utilization of these. The production conditions are largely determined by factors exogenous to the firms comprising the industry, including the economic environment, regulatory...

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...

In river systems, costly upstream pollution abatement creates downstream welfare gains. Absent adequate agreement on how to share the gains, upstream regions lack incentives to reduce pollution levels. We develop a model that makes explicit the impact of water quality on production benefits and...

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 results in two new fairness criteria, absolute and relative...

When actions by one agent force another to deviate from their agreements with a third, “victim” turns into “injurer” in the chain’s subsequent steps. Should the chain’s initiator be responsible only for the direct harm they cause or also bear some of the indirect losses they trigger?...
