## Definition

In economics, Okun's law is an empirically observed relationship between unemployment and losses in a country's production. The "gap version" states that for every 1% increase in the unemployment rate, a country's GDP will be roughly an additional 2% lower than its potential GDP. The "difference version" describes the relationship between quarterly changes in unemployment and quarterly changes in real GDP. The stability and usefulness of the law has been disputed.

### What is 'Okun Gap'

A macroeconomic term that describes the situation when an economy's potential gross domestic product (GDP) differs from its actual gross domestic product. The gap can either be recessionary or inflationary, but will depend on the economy's current state, including levels of inflation and the unemployment rate.

### Explaining 'Okun Gap'

An Okun gap can be expressed in either percentage or absolute terms and will be a measure of how much output, as measured by GDP, the economy produced in a given time period relative to the economy's full-employment level.

Arthur Okun, who is the person credited with discovering Okun's law, among other famous discoveries, was a senior economist at the Counsel of Economic Advisers (CEA) during President Kennedy's term in office and a professor at Yale University.

### Okun Gap FAQ

#### What is Okun's Law equation?

Okun's first relationship caught how changes in the joblessness rate starting with one quarter then onto the next moved with quarterly development in real yield. It is calculated as, Change in the unemployment rate = a + b ∗ (Real yield growth).

#### What is Okun's Law in macroeconomics?

Okun's law shows the relationship between the U.S. economy's unemployment rate and its gross national product (GNP). Okun's law states that when unemployment falls by 1%, GNP rises by 3%. It however only applies to the U.S. economy and only applies when the unemployment rate is between 3% and 7.5%.

#### How can GDP gap be calculated using Okun's Law?

The GDP gap shows the difference between actual GDP and potential GDP. The output gap is calculated as Y–Y* where Y is actual output and Y* is potential output. The percentage GDP gap is the actual GDP minus the potential GDP divided by the potential GDP.

#### How do you calculate Okun coefficient?

Okun's Law Formulay = Actual GDP.y* = Potential GDP.β = Okun Coefficient.u = Unemployment rate of the current year.u* = Unemployment rate of the previous year.y-y* = Output Gap.

It however only applies to the U.S. economy and only applies when the unemployment rate is between 3% and 7.5%.

#### How does Okun's law calculate unemployment rate?

Okun's first relationship caught how changes in the joblessness rate starting with one quarter then onto the next moved with quarterly development in real yield. It is calculated as, Change in the unemployment rate = a + b ∗ (Real yield growth).
