Heterodox Theories (Post-Keynesian, MMT)
Similar to Keynesian Theory but with:

capitalism

is needed
• Fiat money systems as actually practiced
Rx:

• Increase deficits until full employment achieved
• Monetary policy should accommodate fiscal policy

Policy Challenges Today
 Austerity and deficit-cutting or fight unemployment?
 Limits or goals of monetary policy
 Regulation of banking to prevent crises
 Distribution of income
