In Sub-Saharan Africa, mobility through transhumance is a much-valued strategy of pastoralists for dealing with rainfall variability (see Swallow 1994; van den Brink, Bromley, and Chavas 1995; Ellis and Swift 1988). Transhumance is generally practiced in the arid to semi-arid regions of Sub-Saharan Africa, an environment characterized by low mean rainfall and high rainfall variability. Higher r...

This paper analyzes coalition formation in a livestock-pasture system where livestock are privately owned and the pasture is a common property. While standard models predict rather low prospects of cooperation, this paper introduces a cost advantage of cooperation based on Saami reindeer herding that may explain higher coalition participation. In contrast to the existing fishery literature on c...

In this paper, we introduce fruitful concepts of common limit range and joint common limit range for coupled mappings on modified intuitionistic fuzzy metric spaces. An illustrations are also given to justify the notion of common limit range and joint common limit range property for coupled maps. The purpose of this paper is to prove fixed point results for coupled mappings on modified intuitio...

In this work we study problems of common-pool resources from a cooperative point view. particular analyse whether it is possible for agents to agree form coalition coordinate their level appropriation and thus, avoid the tragedy commons. For purpose, investigate how in choose joint (depending on behavior appropriators outside such coalition). Finally, propose way associating with each problem (...

We consider a common pool resource (CPR) where, in the first stage, every firm chooses an equity share on its rivalsiproOts (cross-ownership) and, second firms compete for resource. identify equilibrium shares this setting, and compare them against socially optimal that maximize welfare. Our results show are welfare improving under certain conditions, but can lead to insufficient exploitation o...
