How were Canada and the US affected by Keynesian Economics after the great depression?

Keynesian Economics is a method of analysing the behaviour of key aggregate economic variables such as output, employment, inflation and interest rates. British economist John Maynard Keynes initially developed this analytic structure during the 1930s, as a method of understanding the Great Depression. Later to this time, economists generally believed that cyclical swings in employment and output would be relatively small and self-correcting. This classical approach argued that if overall demand in the economy weakened, causing a temporary drop in production and jobs, the resulting slack labour and product market conditions would force a rapid drop in both wages and prices, which in turn would operate to restore full employment.
