Can identical goods sell at different prices in identical markets when people are perfectly mobile? We provide a formal account of strategic behaviour in large games with many commodities, and exhibit how it drives price dispersion at equilibrium. Interactions between agents are modelled using a Shapley-Shubik market game. We demonstrate the failure of the law of one price in this setup through a robust counterexample. The proposed model, and our findings, constitute an alternative and plausible explanation to some "anomalies" which routinely appear in a wide array of fields, ranging from banking, business economics, to international, and labour economics.
