Monthly prices of exported and imported goods reveal the embargo's striking effect on commodity markets and allow a calculation of its welfare effects. A simple general equilibrium calculation suggests that the embargo cost about 8 percent of America's 1807 GNP, at a time when the trade share was about 13 percent (domestic exports and shipping earnings). The welfare cost was lower than the trade share because the embargo did not completely eliminate trade and because domestic producers successfully shifted production toward previously imported manufactured goods.
