In this paper, we make an exploratory use of computational techniques (genetic algorithms and Monte Carlo simulations) to compute efficient and emergent networks in a spatialized version of the connections model of Jackson and Wolinski (1996). This approach allows us to observe and discuss...

Crucial to the analysis in this paper is the Coasian insight that external costs result from conflicting uses of scarce resources and that responsibility for these costs should not be attributed exclusively to polluters as required by the polluter pays principle (PPP). The paper argues that the...
