The economics of trade and finance that form the TPP’s foundations are rather simple, and have been known since the British political economist David Ricardo described them in the nineteenth century. By enabling countries to make the most of their comparative advantages, the liberalization of trade and investment provides net economic benefits, although it may hurt particular groups that previously benefitted from tariff protections.
