Allais, Maurice ah LEH, moh REES, (1911-...), a French economist, developed theories of economic markets and the efficient use of resources that could be applied to public bodies. For his work, Allais was awarded the Nobel Prize for economics in 1988. Allais's theories focused on how economic efficiency could be combined with social benefits. The principles he developed were used by state-owned enterprises to increase their efficiency. His work was particularly relevant in the economies of Western Europe after World War II (1939-1945), when public ownership of industry was on the increase. Throughout his career, Allais also pursued interests in history and experimental physics, receiving awards in both France and the United States for his work in physics.
