Kalecki was hired by the Oxford Institute of Statistics (OIS) early in 1940. His job there consisted mainly of writing statistical and economic analysis for the British government of the management of war economy. Occasionally he gave lectures at Oxford University. The elaborate reports Kalecki prepared for the government were chiefly about the rationing of goods, and the scheme he developed was very close to the policies adopted later when rationing was introduced. According to George Feiwel, "Kalecki's work of the war period is far less known than it deserves to be".
