Douglas Allen, an economics professor at Simon Fraser University, says his study went viral after he posted it in April and he received positive feedback, leading to interviews on podcasts in Canada, the United States, Europe, and Australia. Even a few politicians reached out, he says.

But as far as media goes, his study received little attention.

Titled “Covid-19 Lockdown Cost/Benefits: A Critical Assessment of the Literature,” the study was officially published on Sept. 29 in the International Journal of the Economics of Business.
