Macroeconomics
The Big Picture
• Modern Macro is “new.”
• Before 1930s, the economy was thought to be
primarily self-regulating (thought that markets
would ‘clear’ by themselves).
• Production and Unemployment in the Great
Depression changed that view.
• Production was extremely low. Employment was
extremely low.
• John Maynard Keynes argues a depressed
economy is the result of inadequate spending
and ‘sticky’ prices.
• Keynes also argues the government could help
out – if C falls, G could rise to temporarily take its
place.
