Trade Agreements, Patents, and Drug Prices: Continuing the Debate

Authors: Amy Kapczynski, Bhaven N. Sampat and Ken Shadlen

Abstract:  The upward-ratcheting of patent protection through trade agreements has generated significant concerns about potential effects on prices of drugs and access to medicines in developing countries. The Trans-Pacific Partnership (TPP) included even more extensive pharmaceutical patent provisions than any before. While President Trump withdrew the US as a signatory to the TPP, the potential for new trade agreements to raise the same set of concerns generated by the TPP remains high. Previous work assessing the TPP argued that new data on pharmaceutical expenditures (and other measures) from countries with recent trade agreements with the U.S. indicated that concerns about pharmaceutical patent protection and drug prices are overblown and it may be time to move on from these debates.

Here we argue that the analysis supporting these claims is misleading because it fails to look at the right drugs at the right points in time, overlooks the temporal dimensions of implementation of provisions in previous trade agreements, and ignores the broader context in which trade agreements are negotiated and implemented. Much more empirical work is needed to understand the impact of previous trade agreements, and the effects of stronger patent protections in developing countries on innovation, access, and prices. Some of the crucial analyses may not be possible until the provisions in the agreements take full effect, which could take some time especially in developing countries where patenting is relatively new.
