ECON 1 Lecture Notes - Lecture 22: Dot-Com Bubble, Fiscal Policy, Monetary Policy
#22 Thursday 4/19 (Ch.34 Economic Policies)
What can policy do to fight recessions?
● Fiscal policy
● Monetary policy
Stabilizing the Economy
● In some years the economy is too weak
○ Unemployment
○ Low wages
○ Poverty
Example: Great Recession 2008-2011
● In other years the economy is too strong
○ Inflation
○ Bubbles
Example: Dot Com Boom 1998-2000
● Government can try to stabilize the economy
Two Policies to Stabilize the Economy
● Monetary policy
○ Federal Reserve Bank (Fed)
○ Controls money supply and interest rates
○ Can lower rates when economy is weak; increase rates when economy is too strong
● Fiscal Policy
○ Federal government
○ Controls public spending and taxes
○ Can increase spending when economy is weak; reduce spending when economy is too strong
Monetary Policy
●In the long run it can not increase output or jobs (long-run determined by LRAS)
● But in the short run it can.
● Example: Great Recession (2008-2011)
High unemployment, widespread poverty
● Massive expansion of money supply by the Fed → low interest rates → more investment → more
aggregate demand → more output and jobs (increasing aggregate demand by making investment
cheaper)
○ Helped the US get out of deep recession
○ Recovery continues today
● The Fed controls the Money Supply (MS)
This allows the Fed to influence the interest rate.
● If Fed increases MS → interest rate declines → AD curve shifts right
● Goal: to reduce unemployment in the short run, the Fed use monetary policy to shift the AD curve
Document Summary
In some years the economy is too weak. In other years the economy is too strong. Government can try to stabilize the economy. Can lower rates when economy is weak; increase rates when economy is too strong. Can increase spending when economy is weak; reduce spending when economy is too strong. In the long run it can not increase output or jobs (long-run determined by lras) But in the short run it can. Massive expansion of money supply by the fed low interest rates more investment more aggregate demand more output and jobs (increasing aggregate demand by making investment cheaper) Helped the us get out of deep recession. The fed controls the money supply (ms) this allows the fed to influence the interest rate. If fed increases ms interest rate declines ad curve shifts right. Goal: to reduce unemployment in the short run, the fed use monetary policy to shift the ad curve.
