1 Comparatve Advantage and Optmal Trade Taxes Arnaud Costnot (MIT), Dave Donaldson (MIT), Jonathan Vogel (Columba) and Iván Wernng (MIT) June 2014
2 Motvaton Two central questons Why do natons trade? 2. How should they conduct trade polcy? Theory of comparatve advantage Influental answer to #1 v Vrtually no mpact on #2
3 Ths Paper Take canoncal Rcardan model smplest and oldest theory of CA new workhorse model for theoretcal and quanttatve work Explore relatonshp... CA Optmal Trade Taxes
4 Man Result Optmal trade taxes: 1. unform across mported goods 2. monotone n CA across exported goods
5 Man Result Examples: zero mport tarff + export taxes ncreasng n CA Postve mport tarff + export subsdes decreasng n CA

10 Smple Economcs More room to manpulate prces n comparatve advantage sectors New perspectve on targeted ndustral polcy larger subsdes for less compettve sectors not from desre to expand output but greater constrants to contract exports to explot monopoly power
11 Two Applcatons Agrculture and Manufacturng examples GT under optmal trade taxes are 20% and 33% larger than under no taxes GT under under optmal unform tarff are only 9% larger than under no taxes Mcro-level heterogenety matters for desgn and gans from optmal trade polcy

53 Optmal Trade Taxes Any soluton to Home's plannng problem can be mplemented by t 0 = 0 Conversely, f t 0 solves the domestc's government problem, then the assocated allocaton and prces must solve Home s plannng problem and satsfy: t 0 = u0 c 0 p 0 1

57 Industral Polcy Revsted
58 Industral Polcy Revsted At the optmal polcy, governments protects a subset of less compettve ndustres but targeted/non-unform subsdes do not stem from a greater desre to expand producton they reflect tghter constrants on ablty to explot monopoly power by contractng exports
