Monetary Policy: The Best Case Scenario

Understanding Monetary Policy

In this video, Alex explains the complexities of monetary policy and how it can be difficult to choose the right tools at the right time. He uses a scenario of a negative shock to aggregate demand to illustrate these difficulties.

The Negative Shock

• A negative shock to aggregate demand is caused by emotions and instincts such as confidence and fear.

• This shock causes consumers to become more pessimistic, borrow and spend less, banks lend less, entrepreneurs cut back on expansions and invest less.

• All of this leads to a decrease in real GDP growth which moves the economy from point A to point B.

The Role of Monetary Policy

• The Fed can combat sluggish growth with monetary policy by increasing the growth rate of the money supply.

• However, choosing the right course of action at the right time is difficult due to three issues: quality of data, timing, and control.

Issues with Monetary Policy

Quality of Data

• It takes time to gather good data on the economy which may be revised years after actual events.

• The Fed cannot wait for revisions but has to act now.

Timing

• The Fed's actions take 6 - 18 months before they affect the economy.

• Even if they identify a problem correctly and act immediately, situations may have changed by then.

Control

• The Fed's control over money supply is incomplete and imperfect since many tools rely on other actors such as banks.

• During times like Great Recession when banks stop lending normally some tools become less effective.

Consequences of Monetary Policy

Undershooting

• If the Fed doesn't stimulate the economy enough to offset the aggregate demand shock, growth will still be sluggish in the short run.

Overshooting

• If the Fed increases money supply beyond what's needed, it can cause inflation and price signals become distorted.

• It's difficult for the Fed to course-correct and reduce inflation rate without causing unemployment.

The Federal Reserve and Inflation

This section discusses how the Federal Reserve brought inflation down to 3% in 1983 under Paul Volcker's leadership, but at the cost of a severe recession.

The Cost of Stimulating the Economy

• Stimulating the economy in the 1970s led to more unemployment in the early 1980s.

Difficulty of Economic Stimulation

• It is not easy for the Fed to hit the "just right" amount of economic stimulation.

• This scenario was considered simple and easy.

Negative Real Shock and Long-run Aggregate Supply Curve Shift

This section discusses a more difficult challenge that the Fed faces when there is a negative real shock and a shift in long-run aggregate supply curve.

Challenges Faced by Fed

• When there is a negative real shock, it becomes challenging for the Fed to manage economic stimulation.

• A shift in long-run aggregate supply curve poses another challenge for managing economic stimulation.
