Events Leading Up to the Great Depression:



Stock prices rose rapidly during the 1920s.
Was it speculation? Was it a stock bubble?
Bernstein disagrees (profits rose 387%).
The market crashed in October, 1929.
Many people borrowed a lot of money to buy
stocks; loans were not paid back; banks went
bankrupt; individuals lost their life savings;
people lost confidence in the economy; many
jobs were lost.

The U.S. Government in the 1930s

In the early- and mid-1930s, the economy worsened partly
because of flawed government policies. The government:
raised taxes in an attempt to balance the budget.
raised interest rates in an attempt to stem the outflow of
gold to other countries.
raised tariffs and quotas in an attempt to protect domestic
industries and employment.

Recession and Depression Symptoms
High unemployment is a serious symptom of a
stagnating economy.
The unemployment rate is the number of people
who do not have a job and are actively looking for
one, as a percentage of the labor force.

In the U.S. the government measures the
unemployment rate by:
1. Counting the number of
people on
unemployment
compensation
2. Counting the number of
people on welfare
3. Taking a survey of
66,000 representative
households
4. Taking a survey of
business leaders

The Natural Rate of Unemployment
According to some government economists, when
unemployment is at approximately 5 or 6 %, the
economy is at “full employment”, or the natural
rate of unemployment.
This is when cyclical and seasonal unemployment
are zero.

The Natural Rate of Unemployment
Keynesian economists claim that when
unemployment is around 5 or 6%, then
further growth in the economy causes
inflation.

The Natural Rate of Unemployment
Classical and Austrian-school economists disagree.
They believe that
inflation is caused by a rising money supply.
we can do better than 5 or 6% unemployment.
in the past, unemployment has been below 5%
while the economy grew, without causing inflation.
