In our policy choice model a government bargaining with domestic SIGs can gain by constraining tariffs through international agreements even if this leads to the use of the less efficient NTBs. This generates two key testable predictions (i) there is imperfect policy substitution, i.e. tighter tariff constraints are not fully offset by the higher NTBs they generate and (ii) the decision to commit to constraints depends on the government's bargaining power rel...
