This paper explores the interplay of political dynamics in trade policy, focusing on how adjustments and ambiguities affect domestic politics. Traditional interpretations based on general equilibrium models overlook the fluidity of political cleavages and shifting preferences driven by changes in expected income. The paper highlights the role of specific sectors, abundant versus scarce factors, and domestic policy interventions that can mitigate ambiguity. It emphasizes the strategic use of trade policy by politicians within a unified model of domestic and foreign policy.

Politics and Trade • Current interpretations based on general equilibrium models • Interests depicted as: • exclusive • consistent • Political parties presented as passive receptacles of interests • Cleavages shift more often, more rapidly than these predict
Politics and Trade: Ambiguity • Why would preferences shift? • Ambiguity arises from relaxing the general equilibrium condition • Preferences then turn on expected income (i.e. trade shapes both rates of return and employment opportunities) • For select groups, trade moves these in opposite directions

Domestic Policy Interventions • Interventions in adjustment can reduce ambiguity (e.g. unemployment benefits, “matching,” and sector’s “break-up” rates) • Interventions tilt swing groups’ preferences

Advantages of this Approach • Politicians can use trade policy as a tool in their competition • Cleavages are fluid • Domestic and foreign policies are integrated in one model • Better equipped to address questions about politics
