What is the natural rate of unemployment?

The natural rate of unemployment refers to the level of unemployment that is expected in a healthy economy when it is operating at full capacity, reflecting the number of people who are jobless due to natural market forces, including frictional and structural factors. It is essentially the average level of unemployment around which the unemployment rate fluctuates in the long term.

This concept acknowledges that there will always be some level of unemployment in a dynamic economy because individuals are constantly moving between jobs, entering the workforce, or leaving it. It does not account for cyclical unemployment, which is the result of economic downturns, nor does it represent an absolute minimum or maximum unemployment rate. Instead, it provides a benchmark for understanding how employment conditions can change based on various economic factors.

In contrast, the other options do not effectively capture the essence of the natural rate of unemployment. The minimum or maximum unemployment levels suggest fixed thresholds rather than the fluid nature of unemployment in an evolving economy, while defining it as the unemployment level during a recession overlooks the broader context of economic conditions.
