We develop a method to measure the incidence of monopolistic markup distortions in the global economy. Using semi-parametric formulas, we measure how trade modifies the deadweight loss of markups through two channels: (1) trade-induced change in markup dispersion, and (2) international...

Trade taxes are often used as (a) a first-best instrument to manipulate the terms-of-trade, or (b) a second-best instrument to correct pre-existing market distortions. We analyze the (in)effectiveness of trade taxes at achieving these two policy goals. To this end, we derive sufficient...
