Unemployment

Definition and Problems of Unemployment

Unemployment refers to the condition in which individuals who are capable of working are unable to find jobs. It is a significant macroeconomic issue because it leads to lost incomes, reduced production, and diminished human capital.

• Lost incomes and production: Unemployment reduces overall economic output and individual well-being.

• Human capital deterioration: Prolonged unemployment can permanently damage a person's job prospects and skills.

• Unequal benefits: Not everyone benefits equally from unemployment; some may find better jobs, but most suffer from lower wages and lost opportunities.

Measuring Unemployment

The U.S. Census Bureau conducts monthly surveys to determine the status of the labor force, dividing the working-age population into two groups:

• People in the labor force: Those employed or actively seeking employment.

• People not in the labor force: Those not working or seeking work (e.g., students, retirees).

Labor Force and Unemployment Categories

To be considered unemployed, a person must meet one of the following criteria:

• Waiting to be called back to a job from which they were laid off.

• Waiting to start a new job within 30 days.

• Actively searching for work.

Labor Market Indicators

• Unemployment rate: The percentage of the labor force that is unemployed.

• Alternative measures: U-1 to U-6, which focus on different aspects of unemployment (e.g., long-term, discouraged workers).

• Classifications: Unemployment is classified into three types: frictional, structural, and cyclical.

Types of Unemployment

• Frictional Unemployment: Caused by normal labor market turnover, such as people changing jobs or entering the workforce.

• Structural Unemployment: Results from changes in technology or foreign competition that alter the skills needed for jobs or the location of jobs.

• Cyclical Unemployment: Occurs when unemployment rises above normal levels during business cycle recessions.

Natural Unemployment and Full Employment

• Natural unemployment rate: The unemployment rate arising from frictional and structural factors when there is no cyclical unemployment.

• Full employment: The situation in which the unemployment rate equals the natural unemployment rate.

Real GDP and Unemployment Over the Cycle

• Potential GDP: The quantity of real GDP produced at full employment.

• Business cycle: Output fluctuates around potential GDP due to cyclical factors.

Employment-to-Population Ratio

• The percentage of the working-age population that has jobs.

Marginally Attached and Discouraged Workers

• Marginally attached worker: Not currently working or looking for work but has looked for work in the recent past.

• Discouraged worker: Marginally attached worker who has stopped looking for a job because of repeated failure.

Inflation and Price Level

Price Level and Inflation

The price level is the average level of prices in the economy, and its persistent rise is called inflation. A persistent fall in the price level is called deflation.

• Problems with inflation: Redistributes income, erodes purchasing power, and distorts resource allocation.

• Hyperinflation: Extremely rapid inflation that erodes the value of money quickly.

Consumer Price Index (CPI)

The CPI measures the average price of goods and services bought by consumers for a fixed basket of goods and services.

• Steps to calculate CPI:

  1. Select the CPI basket.

  2. Find the cost of the CPI basket at current and base period prices.

  3. Calculate CPI for the current period:

• Inflation rate: The percentage change in the price level from one year to the next.

Issues with CPI Measurement

• New goods bias

• Quality change bias

• Commodity substitution bias

• Outlet substitution bias

Alternative Price Indexes

• Personal Consumption Expenditure Price Index (PCEPI): Measures the average price of all goods and services included in GDP.

• Core inflation rate: Excludes food and fuel prices to reveal underlying inflation trends.

Economic Growth

Definition and Measurement

Economic growth is the sustained expansion of production possibilities, measured as the increase in real GDP over time.

• Economic growth rate: The annual percentage change of GDP.

• Real GDP per person: Real GDP divided by the population.

Sources of Economic Growth

• Growth in supply of labor: Aggregate hours worked increases as population grows.

• Growth in labor productivity: Output per hour of labor increases due to better technology, education, or capital.

Aggregate Labor Market

• Labor demand: Shows the quantity of labor demanded at each real wage rate.

• Labor supply: Shows the quantity of labor supplied at each real wage rate.

• The labor market is in equilibrium at the real wage rate where labor supplied equals labor demanded.

Examples and Applications

• If labor productivity increases, the production possibilities frontier (PPF) shifts outward, and real GDP grows.

• Population growth increases aggregate hours and real GDP, but to increase real GDP per person, labor must become more productive.

Potential GDP

• Potential GDP: The quantity of real GDP produced when the quantity of labor employed is at full employment.

• To determine potential GDP, use:

  • Aggregate hours

  • Labor productivity

Long-Term Growth Trends

• From 1901 to 2021, U.S. real GDP per person grew at an average of 2% per year.

• Growth rates vary by country and period, influenced by technological change, population growth, and policy.

Rule of 70

• States that the number of years it takes for a variable to double is approximately 70 divided by the annual percentage growth rate of the variable.

Example: Labor Productivity and Economic Growth

• If the economy is at full employment with 250 billion hours of labor and potential GDP is $20 trillion, an increase in labor productivity will shift the PPF outward and increase real GDP.
