NaturalRate Hypothesis The naturalrate of unemployment theory, also known as the non-accelerating inflation rate of unemployment (NAIRU) theory, was developed by economists Milton Friedman and Edmund Phelps.
Moreover, when unemployment is below the naturalrate, inflation will accelerate.
When unemployment is above the naturalrate, inflation will decelerate.
When the unemploymentrate is equal to the naturalrate, inflation is stable, or non-accelerating.
At point C, the rate of unemployment has increased back to its naturalrate, but inflation remains higher than its initial level.
The long-run Phillips curve is a vertical line at the naturalrate of unemployment, so inflation and unemployment are unrelated in the long run.
Assume the economy starts at point A at the naturalrate of unemployment with an initial inflation rate of 2%, which has been constant for the past few years.
Now assume that the government wants to lower the unemploymentrate.
As labor costs increase, profits decrease, and some workers are let go, increasing the unemploymentrate.
In the short run, it is possible to lower unemployment at the cost of higher inflation, but, eventually, worker expectations will catch up, and the economy will correct itself to the naturalrate of unemployment with higher inflation.
Assume the economy starts at point A, with an initial inflation rate of 2% and the naturalrate of unemployment.
While there are variations between the objectives of different national and international entities, most follow the ones detailed below: Sustainability occurs when an economy achieves a rate of growth which allows an increase in living standards without undue structural and environmental difficulties.
Most economists believe that there will always be a certain amount of frictional, seasonal and structural unemployment (referred to as the naturalrate of unemployment).
As a result, full employment does not mean zero unemployment.
To achieve these goals, macroeconomists develop models that explain the relationship between factors such as national income, output, consumption, unemployment, inflation, savings, investment and international trade.
These models rely on aggregated economic indicators such as GDP, unemployment, and price indices.
