In the spirit of Von Neumann and Morgenstern (Theory of games and economic behavior, Princeton University Press, Princeton, 1944), we introduce a notion of network stability. We study the structure of stable economic networks and their associated stable payoff allocations by analyzing the conditions under which complete networks and star networks (both with desirable property of inclusiveness) are stable. We also address conditions for existence and uniqueness of stable set of networks.

We study the possibility of cartel formation among primary exporters who face an inelastic world demand for their exports. The phenomenon of immiserizing export growth appears as a non-cooperative equilibrium in a two-country export game. With infinite repetitions of the one shot game, we show that `different country size' will be detrimental to the sustenance of the collusive behavior needed for eliminating the possibility of immiserization.
