We relax the single agreement and open membership assumptions that are implicit in the concept of internal and external stability, which has been widely used to analyze the formation of international environmental agreements (IEAs). By means of numerical simulations we investigate the impact of...

The literature on the computation of Nash equilibria in n-person games is dominated by simplicial methods. This paper is the first to introduce a globally convergent algorithm that fully exploits the differentiability present in the problem. It presents an everywhere differentiable homotopy to...
