Macro Chapter 8

Economic Fluctuations, Unemployment, and Inflation

5 Learning Goals1) Characterize fluctuations in economic growth.

2) Relate fluctuations in GDP to employment and the demand for labor.

3) Classify unemployment into three categories.

4) Distinguish the difference between full employment and the natural rate of unemployment and correlate both to potential GDP.

5) Determine inflation’s effect on the economy.

Overall Goals and Objectives

In Chapters 7 & 8, we are measuring and monitoring the major economic indicators of the economy.

Is GDP rising or falling? By how much?

Is employment rising or falling? By how much?

Are prices rising or falling? By how much?

What are the relationships between GDP, employment, and prices?

Class Activity: Identify at least two products that are made in 2014 that you don’t think will be made in 2024. Briefly explain why you think they won’t be produced any longer.

Instability in the Growth of Real GDP: 1960-2013

•Although real GDP in the United States has grown at an average rate of approximately 3%, the growth has been characterized by economic ups-and-downs. Note: periods of recession are indicated with shading.

This section describes the categories of people

Total population divided into two categories:– (1) Under age 16 & institutionalized people– (2) Over age 16

Over age 16 divided into two categories:– (1) Not in labor force – students, retirees, disabled– (2) In labor force

In labor force divided into two categories:– (1) Employed– (2) Unemployed, but want to be employed

Definition of unemployed:

A person not currently employed but (1) actively seeking a job, or (2) waiting to begin or return to a job

Three calculations to know

1) Labor force participation rate = (employed + unemployed) / civilian pop. over age 16

2) Unemployment rate = unemployed / (employed + unemployed) OR unemployed / labor force

3) Employment / population ratio = employed / civilian pop. over age 16

Why are you at FSU?

Here’s one reason:

Please see article “15 Statistics about the jobs market.pdf” on Blackboard

In 2009, the unemployment rate peaked at 10.0% in October. It was so bad, events like this started to happen.

The unemployment rate climbed to 8.3% in February, 2009. It stayed over 8% until September, 2012 (that’s 43 months).

The previous longest streak above 8% was 27 months, from 1981 to 1984.

The unemployment rate climbed to 9.0% in April, 2009. It stayed over 9% until September, 2011 (except for March, 2011 at 8.9%). That’s 29 out of 30 months.

The previous longest streak above 9% was 19 months, from 1982 to 1983.

Mathemagics!

A declining unemployment rate suggests the labor market and the economy are improving.

How can the unemployment rate decline while the employment conditions are actually getting worse?

Mathemagics!Some simple math:

Suppose in August, 8 people are unemployed and 92 are employed (labor force = 100)

Unemployment rate = 8 / 100 = 8.0%

Suppose in September, 7 people are unemployed and 87 are employed (6 people left the labor force; labor force = 94)

Unemployment rate = 7 / 94 = 7.4%

Mathemagics, but…

What happens to the country’s PPC?

What happens to the country’s economic growth potential?

What happens to the country’s income growth potential?

Three Types of Unemployment

3 general reasons why people are unemployed:

(1) Frictional – imperfect information

(2) Structural – workers don’t possess desired skills

(1) Frictional – imperfect information

(2) Structural – workers don’t possess desired skills

(3) Cyclical – result of business cycle

Employment Fluctuations- The Historical Record

Proposal to reduce unemployment:

Recall those two goods you predicted wouldn’t be produced in 2024. I propose we make it illegal to lay off those workers. Keep them employed making those goods.

Class Activity: What do you think will happen to the people who used to make the two products you predicted wouldn’t be produced in 2024? Will they ever work again?

Q8.7 Which of the following is a positive effect of job search and the unemployment that often accompanies it?

1 2 3 4

0% 0%0%0%

1. It keeps wages and income levels low.

2. It permits individuals to better match their skills and preferences with the requirements of a job.

3. It reduces the wage gap between high skill workers and those with few skills.

4. It creates political pressure for an increase in the minimum wage, which will reduce the rate of unemployment in the long run.

Other proposals to reduce unemployment:

These would create jobs, but would they create value to an economy?

Actual and Potential GDP

Potential output is the economy’s maximum sustainable output; occurs when the natural rate of unemployment exists; occurs when full employment exists

Potential output is perhaps best thought of as the 3% growth rate discussed earlier

Actual output can be greater than or less than potential; again, think about the actual growth rate

ActualGDP

Another way to think about these:When you read the BEA report about quarterly GDP, if the reported (actual) growth rate is near 3%, then the economy is at it’s potential output.

At 3% actual growth, the unemployment rate will likely be around 5% (i.e. full employment is 95%)

The economy can never eliminate frictional and structural unemployment for an extended period.

The Effects of Inflation

The Inflation Rate, 1956-2013

•Between 1956 and 1965, the general price level increased at an average annual rate of only 1.6%.

•In contrast, the inflation rate averaged 9.2% from 1973 to 1981, reaching double-digits during several years.

•Since 1982, the average rate of inflation has been lower (2.9% from 1983-2013) and more stable.

Inflation is a persistent increase in the general level of prices

Case Study: Zimbabwe

In February, 2008 a loaf of bread was 200,000 Zimbabwe dollars

In August, 2008, that same loaf of bread was 1.6 trillion dollars

That’s 11.2 million percent!

Video:

Why is inflation “bad”?

1) It reduces investment: long-term projects are more risky

2) It distorts information delivered by prices: relative prices are skewed because some prices adjust more quickly than others

3) It results in less productive use of resources: people will spend more time trying to combat the effects of inflation rather than engaging in productive activity

Key Points:The business cycle varies and is unpredictable

Potential GDP = average annual growth rate = 3%

Natural rate of unemployment = 5% (varies in reality, constant for our purposes)

Natural rate of unemployment means cyclical unemployment = 0; frictional and structural unemployment remain

When actual GDP > potential GDP, unemployment falls, upward pressure on prices

When actual GDP < potential GDP, unemployment rises, downward pressure on prices

Jobs are important, but the production from those jobs is more important (remember: more production first, higher incomes result)

5 Learning Goals1) Characterize fluctuations in economic growth.

2) Relate fluctuations in GDP to employment and the demand for labor.

3) Classify unemployment into three categories.

4) Distinguish the difference between full employment and the natural rate of unemployment and correlate both to potential GDP.

5) Determine inflation’s effect on the economy.
