At the height of the Great Depression in 1933, Keynes published "The Means to Prosperity", which contained specific policy recommendations for tackling unemployment in a global recession, chiefly counter cyclical public spending. "The Means to Prosperity" contains one of the first mentions of the multiplier effect. Keynes's "magnum opus", "The General Theory of Employment, Interest and Money" was published in 1936, and served as a theoretical justification for the interventionist policies Keynes favoured for tackling a recession.
