How is Natural Rate of Unemployment Calculated?
The natural rate of unemployment represents the lowest level of unemployment that an economy can sustain over the long run without triggering inflation. It is often referred to as the "full employment" unemployment rate. Unlike the actual unemployment rate, which fluctuates with the business cycle, the natural rate persists even when the economy is growing normally.
The Calculation Formula
To calculate the natural rate of unemployment, you must sum the frictional and structural unemployment figures and divide them by the total labor force. Note that cyclical unemployment (unemployment caused by recessions) is excluded from this calculation.
Natural Rate = ((Frictional Unemployment + Structural Unemployment) / Total Labor Force) × 100
Understanding the Components
The natural rate is composed of two specific types of unemployment:
1. Frictional Unemployment
This is short-term unemployment that occurs when people are between jobs or are entering the workforce for the first time. It is considered "voluntary" and inevitable in a free market economy. Examples include:
- A recent college graduate looking for their first role.
- A worker who quit their job to find a better opportunity.
- Someone moving to a new city and looking for work.
2. Structural Unemployment
This is a more serious, long-term form of unemployment caused by a mismatch between the skills workers have and the skills employers need. It can also result from geographical mismatches. Examples include:
- Factory workers displaced by automation or robots.
- Typists whose jobs became obsolete due to computers.
- A decline in a specific industry (e.g., coal mining) leaving workers without relevant skills for growing sectors.
Why Cyclical Unemployment is Excluded
When calculating the Natural Rate, we strictly exclude Cyclical Unemployment. Cyclical unemployment occurs due to downturns in the business cycle (recessions). If the economy is in a recession, the Actual Unemployment Rate will be higher than the Natural Rate.
Conversely, during an intense economic boom, the Actual Unemployment Rate can temporarily dip below the Natural Rate, though this often leads to high inflation.
Example Calculation
Let's assume an economy has the following statistics:
- Frictional Unemployed: 2 million people
- Structural Unemployed: 3 million people
- Cyclical Unemployed: 1 million people (Ignore this for Natural Rate)
- Total Labor Force: 100 million people
Step 1: Add Frictional and Structural unemployment.
2,000,000 + 3,000,000 = 5,000,000
Step 2: Divide by the Total Labor Force.
5,000,000 / 100,000,000 = 0.05
Step 3: Convert to percentage.
0.05 × 100 = 5.0%
Why This Metric Matters
Economists and policymakers, such as the Federal Reserve, use the natural rate of unemployment to gauge the health of the economy. If actual unemployment is equal to the natural rate, the economy is said to be at "full employment." If policymakers try to push unemployment below this natural limit artificially (by printing too much money), it typically results in accelerating inflation without permanently lowering unemployment.
