Economist and physician Jay Bhattacharya of Stanford University talks about the pandemic with EconTalk host Russ Roberts. Bhattacharya, along with Sunetra Gupta of the University of Oxford and Martin Kulldorff of Harvard University, authored The Great Barrington Declaration, which advocates a very different approach to fighting the pandemic than current policy and practice. Bhattacharya and his colleagues argue the best way to reduce overall harm is to focus protection efforts on those most at risk, while allowing low-risk populations to return to a more normal way of life. Bhattacharya argues that we have greatly neglected the costs of lockdown and self-quarantine.
