Heterogeneous effects of tariff and nontariff trade‐policy barriers in quantitative general equilibrium
定量一般均衡中关税与非关税贸易壁垒的异质效应
Structural quantitative work in international economics typically models trade costs as a log‐linear function of exogenous trade‐policy variables. We propose a structural approach that allows for a nonparametric relationship and for treating tariff and nontariff trade‐policy variables as potentially endogenous. The data reject the assumption of log‐linearity of trade costs in both tariff‐ and nontariff‐policy variables. We assess the effects of a unilateral increase of US…
