We develop a simple firm-based automaton model for global economic interdependence of countries using modern notions of self-organized criticality and recently developed dynamical renormalization-group methods. We demonstrate how extremely strong statistical correlations can naturally develop...

We construct a simple firm-based automata model for global economic inter-dependence of countries using modern notions of self-organized criticality and recently developed dynamical-renormalization-group methods (e.g., L. Pietronero et al., Phys. Rev. Lett., 72(11):1690 (1994); J. Hasty and K....

The authors report on technical work which examines the implications of combining complementarities and convex adjustment costs in a model of economic reform. The main results are that the optimal pace of reform is higher if there is a larger initial crisis, stronger pro-reform institutions, and...

We provide a direct proof of a representation theorem for additive cost sharing methods as sums of path methods. Also, by directly considering the paths that generate some common additive cost sharing methods (Aumann-Shapley, Shapley Shubik, and Serial Cost) we show that they are consistent....

We describe the construction and analysis of asymmetric Cost Sharing mechanisms, in which a variety of axioms are applied to subsets of the agents/goods. We show that the analysis can be quite subtle as apparently similar axiomatizations lead to significantly different results; in particular,...
