Tim Harford, who writes the Financial Times‘s “Undercover Economist” column, has appeared on our blog many times. This guest post is part of a series adapted from his new book The Undercover Economist Strikes Back: How to Run or Ruin an Economy.
Robert A. Radford studied economics at Cambridge University, and worked at the International Monetary Fund. In between, he spent half the war in a German prison camp, and on his release wrote an article, “The Economic Organization of a P.O.W. Camp.” It gives a surprising insight into economic recessions.
The building blocks of the P.O.W. camp economy were parcels of food and cigarettes that the prisoners received from the Red Cross. These parcels were standardized—everybody got the same, beyond the occasional package from home. Occasionally, the Red Cross received bumper supplies, or ran short; in those circumstances everybody enjoyed a surplus or a shortage. Naturally enough, while prisoners had equal rations, they did not have identical preferences. The Sikhs didn’t have much use for their rations of beef or razor blades, for example; the French were desperate for more coffee; the English wanted more tea.
