The 1974-1975 period experienced a recession caused by a supply shock. In particular following the Arab-Israeli War of 1973, the Organization of the Petroleum Exporting Countries (OPEC) took actions that increased the price of a barrel of oil from less than $3 to more than $10 (Hubbard and O'Brien, 2015). This is illustrated in the aggregate supply-aggregate demand figure below. Assume that the aggregate demand curve did not shift between 1974 and 1975.
