This article explores the evolution of a civilized exchange economy from an anarchistic environment. I analyze a model of stochastic jungle bargaining mechanism and show that it implements the Talmud Rule allocation (Aumann, R. J., and M. Maschler. 1985. "Game Theoretic Analysis of a Bankruptcy Problem from the Talmud." Journal of Economic Theory 36 (2): 195-213.) in subgame perfect equilibrium. This Pareto-inefficient allocation constitutes the initial endowment of a stable exchange economy and supports stable Walrasian equilibria, implying that civilized economies could evolve from a Hobbesian state of nature without social contract or regulator. The moral implications of these results are also briefly discussed.
