The socialist calculation debate

In 1920 Mises published a short paper asking a question that sounds practical and turned out to be theoretical: in an economy without private ownership of the means of production, how would anyone know whether a factory, a railway or a method of production was worth building.

The argument that followed ran for two decades, drew in Lange, Lerner, Dickinson, Robbins and Hayek, and was widely thought to have been settled by 1940. It was reopened in the 1980s by historians of economic thought, and what it established is still disputed by the people who study it.

Seven lessons. The first states the problem with no politics attached. The second gives Mises's argument as he made it. The third gives the market socialist reply, which is a serious piece of economics and is presented as its author presented it. The fourth follows Hayek's shift from calculation to knowledge, which is where the most influential paper in this tradition came from.

The last three are about the record. What most economists took the debate to have shown at the time. The reading that emerged decades later, on which both sides had been arguing past each other. And a closing lesson on what the argument settled, what it did not, and why the collapse of planned economies after 1989 is evidence rather than a controlled test.

This is contested intellectual history and it is taught as such. Nothing here is a policy position, a forecast, or a view about any security. ValueScreener is a research tool, and this academy is free to read without an account.
