This document discusses mixed economies. A mixed economy is between a command economy and a market economy, with some level of government intervention. John Maynard Keynes first proposed mixed economies in the 1930s during the Great Depression to allow government intervention during recessions while maintaining a predominantly private sector. Mixed economies aim to adequately meet citizen demands and national interests while allowing flexibility. Examples given are the US and Sweden having more market aspects and China and Russia having more government aspects. The US economy is described as about 1/3 government activity while China is about 2/3. Mixed economies are concluded to be a goal for developed economies but not necessarily for developing economies still finding their economic path.
