General Equilibrium Theory. Keynesian economics. The theories forming the basis of Keynesian economics were first presented by the British economist John Maynard Keynes in his book, The General Theory of Employment, Interest and Money, published in 1936, during the Great Depression.
Keynes contrasted his approach to the aggregate supply-focused 'classical' economics that preceded his book. The interpretations of Keynes that followed are contentious and several schools of economic thought claim his legacy. Keynesian economists often argue that private sector decisions sometimes lead to inefficient macroeconomic outcomes which require active policy responses by the public sector, in particular, monetary policy actions by the central bank and fiscal policy actions by the government, in order to stabilize output over the business cycle.[2] Keynesian economics advocates a mixed economy – predominantly private sector, but with a role for government intervention during recessions.
Overview[edit] Theory[edit] Macroeconomics. Circulation in macroeconomics.
Macroeconomics (from the Greek prefix makro- meaning "large" and economics) is a branch of economics dealing with the performance, structure, behavior, and decision-making of an economy as a whole, rather than individual markets. This includes national, regional, and global economies.[1][2] With microeconomics, macroeconomics is one of the two most general fields in economics.
