摘要

We highlight the key role of changes in the transportation and use of intermediate inputs in determining the CO2 consequences of reductions in trade barriers such as tariffs and transpor-tation efficiency improvements. Reductions in trade barriers increase gross flows relative to value added - a lengthening of value chains - thereby increasing transportation emissions. Reductions in trade barriers also increase wages relative to the price of other goods, which in-creases the quantity of intermediates relative to labor used in production and, therefore, emis-sions per value added. Liberalization schemes that temper these channels could achieve substantial output increases with modest increases in CO2.(c) 2023 Elsevier B.V. All rights reserved.
