Economic Theories

The different:

rational expectations:
monetarists:
Keynesian: we are all dead in the long run so interfere in the economy and do all you can. (there is a 45 degree line in a graph, there is a graph associated with this)

classical: no to little government interference. the economy is self regulated.

supply-side economics: you should have tax cuts for the wealthy because when the wealthy have more they spend more. This is trickle-down theory.
