ECONOMIC LESSONS FROM COVID-19

ONE OF THE most important things economists can do in a pandemic is not forget what we know. We know that central planners don’t have enough information and insight about the lives and activities of 330 million people to plan those lives in a thoughtful way.

We know that externalities pose problems for the straightforward “leave it to the market” viewpoint, but that large government interventions create new problems. In the rush to make pandemic policy, too many of these lessons were cast aside.

1 CENTRAL PLANNING

In his 1922 book, Socialism, Ludwig von Mises argued that without markets, central planners would not know how to “calculate.” Specifically, they wouldn’t know how many of various goods to produce, how to produce them, and whom to allocate them to. In the 1930s and 1940s, Mises’ student Friedrich Hayek advanced the argument by noting the ways an economy depends on dispersed information that exists in the minds of millions of people. This information about individuals’ “circumstances of time and place,” he wrote, could not be captured by a central planner. Hayek’s most famous contribution to the debate was his 1945 article “The Use of Knowledge in Society,” published in the American Economic Review. That article led modern Hayekians to use the phrase “local knowledge” as a shorthand for Hayek’s “circumstances of time and place.”

By the end of the Cold War, most economists—even some socialists—were acknowledging that Mises and Hayek had
