Ever since the coronavirus emerged in Europe, Sweden has captured international attention by conducting an unorthodox, open-air experiment. It has allowed the world to examine what happens in a pandemic when a government allows life to carry on largely unhindered. This is what has happened: Not only have thousands of more people died than in neighboring countries that imposed lockdowns, but Sweden’s economy has fared little better.

“They literally gained nothing,” said Jacob F. Kirkegaard, a senior fellow at the Peterson Institute for International Economics in Washington. “It’s a self-inflicted wound, and they have no economic gains.” The results of Sweden’s experience are relevant well beyond Scandinavian shores. In the United States, where the virus is spreading with alarming speed, many states have — at President Trump’s urging — avoided lockdowns or lifted them prematurely on the assumption that this would foster economic revival, allowing people to return to workplaces, shops and restaurants.

In Britain, Prime Minister Boris Johnson — previously hospitalized with Covid-19 — reopened pubs and restaurants last weekend in a bid to restore normal economic life.

Implicit in these approaches is the assumption that governments must balance saving lives against the imperative to spare jobs, with the extra health risks of rolling back social distancing potentially justified by a resulting boost to prosperity. But Sweden’s grim result — more death, and nearly equal economic damage — suggests that the supposed choice between lives and paychecks is a false one: A failure to impose social distancing can cost lives and jobs at the same time.

Sweden put stock in the sensibility of its people as it largely avoided imposing government prohibitions. The government allowed restaurants, gyms, shops, playgrounds and most schools to remain open. By contrast, Denmark and Norway opted for strict quarantines, banning large groups and locking down shops and restaurants.
