WHEN AGGREGATE DEMAND INCREASES, _____________FALLS AND ___________RISES
UNEMPLOYMENT FALLS AND INFLATION RISES AS A RESULT, THERE IS A SHORT RUN TRADE OFF
WHEN THE INFLATION RATE IS AT THE EXPECTED LEVEL, THE __________________________ I.E. THE LONG RUN PHILLIPS CURVE
UNEMPLOYMENT LEVEL IS AT ITS NATURAL RATE,
WHEN AGGREGATE DEMAND DECREASES, __________RISES AND ___________FALLS
UNEMPLOYMENT RISES, AND INFLATION FALLS, AS A RESULT, THERE IS A SHORT RUN TRADE OFF
NATURAL RATE OF UNEMPLOYMENT
UNEMPLOYMENT, IN THE LONG RUN, GOES TO THE NATURAL RATE OF UNEMPLOYMENT, WHEN OUTPUT RETURNS TO POTENTIAL GDP. AT THIS OUTPUT LEVEL, THERE IS NO CYCLICAL UNEMPLOYMENT; BUT THERE DOES REMAIN STRUCTURAL AND FRICTIONAL UNEMPLOYMENT. THERE 2 ARE NOT PREDICTIBALY AFFECTED BY INFLATION.
LUCAS AND SARGENT CONCLUDED THAT THE FED COULD AFFECT OUT AND EMPLOYMENT BUT ONLY THROUGH
UNEXPECTED CHANGES TO THE MONEY SUPPLY
THE LONG RUN AGGREGATE SUPPLY CURVE MEANS A
VERTICLE LONG RUN PHILLIPS CURVE
IN THE LONG RUN EMPLOYMENT IS DETERMINED BY OUTPUT,
WHICH IN THE LONG RUN DOESN'T DEPEND ON THE PRICE LEVEL
RATIONAL EXPECTATIONS
WORKERS AND FIMS ANITICIPATING AND ADJUSTING THEIR EXPERIENCES ABOUT INFLATION ACCORIDNGLY
ADAPTIVE EXPECTATIONS
WORKERS AND FIRMS EXPECTING INFLATION TO BE THE SAME AS IT WAS LAST PERIOD
SUPPLY SHOCK SHIFTS SRAS CURVE AND THE SHORT RUN PHILIPS CURVE PROVES THAT BY MOVING ONE MAKES THE OTHER
WORSE. SO FEDS CHOSE EXPANSIONARY MONETARY POLICY, REDUCING UNEMPLOYMENT AND INCREASING INFLATION
phillips curve
a graph showing the short run relationship between unemployment and inflation rate
each point on the phillips curve represents
a possible comboination of unemployment rate and inflation rate that might be observed in a given year
if expected inflation is higher than actual real wages in the economy will turn out to be ______________than expected real wages; consequently, firms will hire ______________ workers than they had planned
higher; fewer
using ad as model to explain phillips curve
in the ad-as model, a small aggregate demand increase leads to low inflation and high unemployment. a stronger ad increase results in lower unemployment but more inflation- the short run phillips curve
why doesn't the phillips curve represent a permanent trade-off between unemployment and inflation in the long run?
in the long run, aggregate supply is vertical
the short run phillips curve exhibits _____________________ where as, he long run phillips curve shows __________________
relationship between unemployment and inflation; there is not permanent trade off between inflation and unemployment
economists in the early 1960s thought of the phillips curve as a "policy Menu" because they thought that the phillips curve
represented a structural relationship in the economy that would not change as a result of policy change
as expectations of inflation increase, the short run phillips curve will
shift right
2 great macroeconomic problems that the feds deal with (in the short run)
unemployment and inflation
the fed wants to move from a point on the short run phillips curve representing high unemployment and low inflation to a point representing lower unemployment and higher inflation then it should
use contractionary monetary policy
the long run phillips curve is
vertical at the natural rate of unemployment
assuming people have rational expectations
when the fed uses monetary policy, people quickly realize the impact that will be created by the policy, adjust wages and prices, and inflation will adjust to the new expectations which means the policy will not affect real gdp
WHY THE NATURAL RATE OF UNEMPLOYMENT MAY CHANGE
1. DEMOGRAPHIC CHANGES 2. CHANGES IN LABOR MARKET INSTITUTIONS 3. PAST HIGH RATES
REAL BUSINESS CYCLE MODEL
A MACROECONOMIC MODEL THAT FOCUS ON REAL RATHER THAN MONETARY EXPLANATIONS OF THE FLUCTUATIONS IN REAL GDP. THESE 2 APPROACHES ARE AKA AS NEW CLASSICAL MACROECONOMICS
MOST ECONOMISTS BELIEVE AN INCREASE IN INFLATION WILL QUICKLY LEAD TO
AN INCREASE IN WAGES
RATIONAL EXPECTATIONS
EXPECTATIONS FORMED BY ISING ALL AVAILABLE INFORMATION ABOUT AN ECONOMIC VARIABLE
HOW LONG THE ECONOMY STAYS IN THE LONG RUN IS DEPENDENT UPON
HOW FAST FIRMS AND WORKERS ADJUST THEIR EXPECTATIONS ABOUT FUTURE INFLATION
BASIS FOR THE SHORT RUN PHILLIPS CURVE
IF ACTUAL INFLATION IS GREATER THAN EXPECTED INFLATION, THE ACTUAL REAL WAGE IS LESS THAN THE EXPECTED REAL WAGE AND UNEMPLOYMENT RATE FALLS. IF ACTUAL INFLATION IS LESS THAN EXPECTED INFLATION, THE ACTUAL REAL WAGE IS GREATER THAN THE EXPECTED REAL WAGE AND THE UNEMPLOYMENT RATE RISES. FRIEDMAN
BECAUSE ANY RATE OF UNEMPLOYMENT OTHER THAN THE NATURAL RATE RESULTS IN AN INCREASE OR DECREASES IN INFLATION, THE NATURAL RATE OF EMPPOLOYMENT IS SOMETIMES CALLED
NON-ACCELERATING INFLATION RATE OF UNEMPLOMENT OR NAIRCU
models that use factors, such as technology shocks, to explain fluctuations in real gdp instead of change in the money supply are called?
REAL BUSINESS CYCLE MODELS
REAL BUSINESS CYCLE MODELS ARE BASED ON
REAL, NOT MONETARY FACTORS
WHEN A POLICY HAS NO EFFECT ON EMPLOYMENT, THE ______________RUN PHILLIPS CURVE WOULD BE VERTICAL ALSO
SHORT RUN, LUCAS AND SARGENT
A SUPPLY SHOCK SHIFTS THE ___________ _________________________PHILLIPS CURVE
SRAS CURVE AND THE SHORT RUN
FREIDMAN SAYS, THERE IS ALWAYS A TEMPORARY
TRADEOFF BETWEEN INFLATION AND UNEMPLOY MENT, THERE IS NO PERMANENT TRADEOFF, THE TEMPORARY TRADE OFF COMES FROM UNANTICIPTED INFLATION
if actual inflation is higher than expected inflation the
actual real wage is less than the expected wage; unemployment falls.
which of the following will not have an effect on the natural rate of unemployment
changes in monetary policy
phillips curve
graph showing the short run relationship between the unemployment rate and the inflation rate
short run trade off between unemployment and inflation plays a role in the fed's ____________policy
monetary policy
according to the real business cycle models
inflation can change due to movements in the money supply, however, fluctuations in real gdp are mainly explained by changes in the level of technology
Phillips says there is usually an ________________ between unemployment and inflation
inverse relationship
the trade off between unemployment and inflation exists in the short run - a period as long as a several year ----but disappears in the _______________
longrun
during the 1960s the phillips curve was a
structural relationship; a relationship that depends on the basic behavior of consumers and firms that remains unchanged over long periods of time, which in the 1960s APPEARED TO remain sable, BUT THIS IS NOT TRUE
milton friedman argued that the phillips curve did not represent a permanent trade-off between unemployment and inflation since
the long run phillips curve is vertical, there is no trade-offs between unemployment and inflation in the long run
the short run trade off between the rate of inflation and the unemployment rate is best represented by
the phillips curve
if in the long run, real gdp returns to its potential level, then in the long run
the phillips curve is vertical
suppose that the inflation rate is increasing each year for a number of years, then
the rational expectations hypothesis is likely to give more accurate forecasts because if workers or firms have rational expectations, then they will use all the available information to forecast future inflation
the phillips curve shows
the relationship between the unemployment and the inflation rates
the phillip curve exhibits
the relationship between unemployment and inflations rates
