Vaccines: Billions in Costs, Trillions in Benefits

Bloomberg: As sections of the global economy tip-toe toward reopening, it’s becoming clearer that a full recovery from the worst slump since the 1930s will be impossible until a vaccine or treatment is found for the deadly coronavirus.

Consumers will stay on edge and companies will be held back as temperature checks and distancing rules are set to remain in workplaces, restaurants, schools, airports, sports stadiums and more.

China — the first major economy consumed by the virus and the first to emerge on the other side — has been able to revive production but not demand. The lesson for other economies: it’ll be a stop-start path back toward normal.

There’s also the risk of new flare-ups. Some 108 million people in China’s northeast region have been put back under varying degrees of lockdown amid a new cluster of infections. Doctors there are also seeing the coronavirus manifest differently, suggesting that it may be changing in unknown ways.
In South Korea – where the virus was controlled without a hard lockdown – consumer spending remains weak as infections continue to pop up.

…Harvard University professor Carmen Reinhart, who is the incoming chief economist of the World Bank, had a similar message. “We’re not going to have something akin to full normalization unless we (a) have a vaccine and (b) — and this is a big if — that vaccine is accessible to the global population at large,” she told the Harvard Gazette.

The virus is being beaten back and there are reasons for optimism but I agree with Reinhart that we won’t get full normalization without a vaccine. The world economy is on the order of $90 trillion and the IMF is projecting a 3% decline instead of an expected 3.3% increase so a loss to the world economy of around $6 trillion in 2020. Growth will probably return in 2021 and there will be some catchup but the IMF projects a cumulative loss of 9 trillion. Ending the pandemic early could generate hundreds of billions, even trillions, in output–that’s why Susan Athey, Nobel laureate Michael Kremer, Chris Snyder and myself advocate for going big on vaccines. It’s billions in costs and trillions in benefits. Warp speed ahead!
