Debates on Macroeconomic Policy
Relationship between inflation and unemployment is inverse
The Phillips Curve expresses the inverse relationship of unemployment and inflation. - aggregate demand - ª unemployment - « inflation - ª - aggregate demand - « unemployment - ª inflation - « - on Fig. 15.2, the inverse relationship is shown.
**The curve is rarely straight - also used by governments as a policy menu. Expansionary fiscal or monetary policies would move an economy up the curve, contractionary policies would cause a move down. - the effect to which the curve is applicable can be shown in 3 different time periods.
• There was generally higher inflation with lower unemployment (thus there was demand pull inflation). Since the points fell in a broad band a Phillips Curve could be drawn and used to predict how stabilization policies would affect the economy
• Generally inflation and unemployment were both higher %. Their relationship was sometimes direct: a rise in inflation would accompany a rise or non-movement in unemployment. This caused stagflation
• Unemployment rates remained generally high, but inflation rates generally lower. Because of an inconsistent relationship, the Phillips curve could not be drawn for this period.
• Inflation was lower because oil prices dropped, reducing cost-push inflation, and because of an economic recession.
Wage & Price controls may reduce inflation in the short run, but after the controls are removed, inflation almost instantaneously rises.Is It Effective?
Monetarism: It is an economic perspective that emphasizes the influence of money on the economy & the ability of private markets to accommodate change
Monetarists VS Keynesians
-Referred to the economist Keynesians, fiscal and monetary policies perform a beneficial role by smoothing the ups and downs of the business cycle
* Because they stress the importance of money, monetarists blame unwise use of monetary policies in particular.
Concept Central to Monetarism known as
Velocity of Money : the number of times, on average, the money is spent on final goods and services during given year is the velocity of money
1) Nominal GDP
2) $800 billion
16 = $ 50 billion
Equation of Exchange - the money supply multiplied by the velocity of money equals price level multiplied by real output.
Given: Nominal GDP = P x Q
800 billion = 2.0 x 400 billion
Money Supplied (M) x Velocity of Money (V) = price level (P) x real output (Q)
The Quantity of Money – a theory stating that the velocity of money and real output are relatively stable over short periods.
Crowding - Out - Effect:The effect of more government borrowing raising interest rates, which reduces or “crowds out” private investment spending
