Analyzing antimicrobial resistance as a series of collective action problems

Policy Studies Journal, Volume 52, Issue 4, Page 833-856, November 2024.
Abstract Antimicrobial resistance (AMR) causes over 1.27 million deaths annually, making it one of today's most urgent health threats. Given its urgency, there are often calls for large‐scale global initiatives to address AMR. However, theories of collective action have yet to be applied to the problem in a systematic and holistic manner.
