Trade and Security, I: Anarchy James E. Anderson and Douglas Marcouiller, S.J.


Market exchange is subject to an endogenously-determined level of predation which impedes specialization and gains from trade. Utility-maximizing agents opt between careers in specialized production and careers in predation. Three types of equilibria may emerge, autarky (with no predation and no defense), an insecure exchange equilibrium (with predation and defense), or a secure exchange equilibrium (in which defense completely deters predation). We analyze the influence of key parameters on the type of equilibrium which emerges. We also analyze changes in the welfare of groups of agents (the predators and specialized producers in both the richer region and the poorer region) as exogenous shocks occur in the technology of security. Since changes in security have terms of trade effects, some producers may be hurt by enhanced security. We show cases of 'immiserizing security' in which large poor countries are harmed by increased security.

This book explores how the European Union responds to the ongoing challenges to the liberal international order. These challenges arise both within the EU itself and beyond its borders, and put into question the values of free trade and liberal democracy.
