This paper estimates the potential social cost of trade barriers using the Harberger and the Tullock/Posner approaches for a sample of U.S. food and tobacco manufacturing industries. In addition, it tests the relationship between the computed welfare losses and special-interest political activity (PAC contributions). If all rents were dissipated through rent seeking, the social cost of trade barriers would be about 12.5 percent of domestic consumption and would be particularly large for sugar and milk products where quotas are the main instrument of protection. Furthermore, the results indicate that welfare losses are positively associated with industry lobbying but the strength of such association is strongly dependent on industry concentration.
