Allgemeine Theorie der Beschäftigung, des Zinses und des Geldes
Keynesian economics developed during and after the Great Depression from the ideas presented by Keynes in his 1936 book, "The General Theory of Employment, Interest and Money". Keynes' approach was a stark contrast to the aggregate supply-focused classical economics that preceded his book. Interpreting Keynes's work is a contentious topic, and several schools of economic thought claim his legacy.
