How much monopoly power did the United States possess in the world cotton market and what would have been the effect of an optimal export tax? This paper estimates the elasticity of foreign demand for U.S. cotton exports and uses the elasticity in a simple partial equilibrium model to calculate the optimal export tax and its effect on prices, trade, and welfare. The results indicate that the export demand elasticity for U.S. cotton was about -1.7 and that the optimal export tax of about 50 percent would have raised U.S. welfare by about $6 million, about 0.1 percent of U.S. GDP or about 0.5 percent of the South's GDP.
