The Modern Macroeconomic Consensus
KRUGMAN'S MACROECONOMICS for AP* Margaret Ray and David Anderson
Biblical Integration
: • Money is not wealth, it is just merely a resource given to us by God to sustain our life her on this earth. Economist even recognize that gold is merely a shiny mineral whose sole value lies in the fact that others hold it to be of value. The true believer recognizes that Scripture and the blood of Christ are intrinsically valuable. They retain their value even if the world denies their efficacy.

: • The elements of the modern macroeconomic consensus • The main remaining disputes
The Modern Consensus
The previous module separated economic debates into several macroeconomic schools of thought. On paper, there are striking differences between some of them.
However in practice, as more years of data have been observed, there exists more of a growing consensus amongst macroeconomists then the previous module might suggest.
The Modern Consensus
Should Monetary Policy Be Used in a Discretionary Way?
A. Is Expansionary Monetary Policy Helpful in Fighting Recessions?
Classical economics really didn’t believe that monetary policy would reverse a recession. Keynesians thought it could have limited effectiveness.
Should Monetary Policy Be Used in a Discretionary Way?
• Milton Friedman and his followers convinced economists that monetary policy is
effective
.
• Nearly all macroeconomists now agree that monetary policy can be used to shift the aggregate demand curve and to
reduce
• The
classical
economic instability.
view that changes in the money supply affect only aggregate prices, not aggregate output, has few supporters today.
• The view once held by some Keynesian economists —that changes in the money supply have
little
effect —has equally few supporters.
• Now, it is generally agreed that monetary policy is ineffective only in the case of a
liquidity
trap.

B. Is Expansionary Fiscal Policy Effective in Fighting Recessions?
Classical
macroeconomists were even more opposed to fiscal expansion than monetary expansion.
Keynesian
economists, on the other hand, gave fiscal policy a central role in fighting recessions.
Should Monetary Policy Be Used in a Discretionary Way?
Monetarists
argued that fiscal policy was ineffective as long as the money supply was held constant. But that strong view has become relatively rare.
Most macroeconomists now agree that
fiscal
policy, like
monetary
policy, can shift the aggregate demand curve.
Most macroeconomists also agree that the government
should not
seek to balance the budget regardless of the state of the economy: they agree that the role of the budget as an automatic
stabilizer
helps keep the economy on an even keel.

C. Can Monetary and/or Fiscal Policy Reduce Unemployment in the Long- Run?
Classical
macroeconomists didn’t believe the government could do anything about unemployment. Some Keynesian economists moved to the opposite extreme, arguing that
expansionary
policies could be used to achieve a permanently low unemployment rate, perhaps at the cost of some
inflation
.
Monetarists
believed that unemployment could not be kept below the natural rate.
Should Monetary Policy Be Used in a Discretionary Way?
Almost all macroeconomists now accept the
natural
rate hypothesis and agree on the limitations of monetary and fiscal policy.
They believe that effective monetary and fiscal policy can limit the size of fluctuations of the actual
unemployment
rate around the natural rate, but can’t keep
unemployment
below the natural rate.

D. Should Fiscal Policy Be Used in a Discretionary Way?
Today most macroeconomists believe that tax cuts and spending increases are at least somewhat effective in increasing aggregate demand.
Should Monetary Policy Be Used in a Discretionary Way?
Many, but not all, macroeconomists believe that
discretionary
fiscal policy is usually counterproductive: the
lags
in adjusting fiscal policy mean that, all too often, policies Intended to fight a slump end up intensifying a
boom
.
As a result, the macroeconomic consensus gives
monetary
policy the lead role in economic stabilization.
Discretionary
fiscal policy plays the leading role only in special circumstances when monetary policy is ineffective, such as those facing Japan during the 1990s when interest rates were at or near the zero bound and the economy was in a liquidity trap.

E. Should Monetary Policy Be Used in a Discretionary Way?
Classical macroeconomists didn’t think that monetary policy should be used to fight recessions; Keynesian economists didn’t oppose discretionary monetary policy, but they were skeptical about its effectiveness. Monetarists argued that discretionary monetary policy was doing more harm than good.
Should Monetary Policy Be Used in a Discretionary Way?
Today there is a broad consensus among macroeconomists on these points: Monetary policy should play the main role in
stabilization
policy The
central bank
should be independent, insulated from political pressures, in order to avoid a political business cycle.
Discretionary
fiscal policy should be used sparingly, both because of policy lags and because of the risks of a political business cycle.
Should Monetary Policy Be Used in a Discretionary Way?
1. Central Bank
Targets Some central banks have announced specified inflation targets. This provides more information to the public about how the central bank would take action if actual inflation got out of line with the target.
The Federal Reserve does not announce a target rate of inflation, although some observers believe that Fed actions are consistent with a target of about 2%.

2.
Asset
Prices Should the Fed be pro-actively influencing the stock market, real estate market or any asset market?
For example, if the Fed thought the stock market was at an unsustainably high level, should the Fed intervene and try to slow down investors? Some people don’t want the Fed to intervene in any market.
However, if the stock market bubble bursts, the damage can be very painful, so maybe the Fed should prevent that from happening.

3. Unconventional Monetary Policies
Desperate times require desperate measures.
In 2008 when the financial system seemed on the verge of collapse, the Fed took some steps that don’t normally appear in the Fed’s playbook.
