Abstract
Nontariff barriers to trade are most pervasive when deteriorating macroeconomic conditions give rise to demands for protection by pressure groups, when countries are sufficiently large to give policymakers incentives to impose protection, and when domestic institutions enhance the ability of public officials to act on these incentives. Statistical results based on a sample of advanced industrial countries during the 1980s support the argument that the incidence of nontariff barriers tends to be greatest when the preferences of pressure groups and policymakers converge. More attention should be devoted to the interaction between societal and statist factors in cross-national studies of trade policy.
