Question 5

Natural rate of unemployment equals the sum of frictional and structural unemployment.

The natural rate of unemployment is defined as the combination of frictional and structural unemployment. This reflects the unemployment that exists when the economy is at full employment, excluding cyclical unemployment.

A) cyclical + structural + frictional

This option is incorrect because it includes cyclical unemployment, which does not contribute to the natural rate. The natural rate specifically excludes cyclical unemployment, which arises during economic downturns.

B) frictional + structural

This option is correct as it accurately describes the components that constitute the natural rate of unemployment. Frictional unemployment occurs when individuals are temporarily out of work while transitioning between jobs, and structural unemployment results from mismatches between skills and job requirements.

C) seasonal + cyclical + frictional

This option is incorrect because it incorporates seasonal and cyclical unemployment. The natural rate of unemployment does not include seasonal variations or cyclical fluctuations that occur due to economic cycles.

D) frictional + discouraged

This option is incorrect as it suggests that discouraged workers, who have stopped looking for employment, contribute to the natural rate. The natural rate focuses solely on those actively seeking work, specifically through frictional and structural unemployment.

Conclusion

The correct answer, B, accurately identifies the components that make up the natural rate of unemployment, which are frictional and structural. All other options fail to recognize the exclusion of cyclical unemployment and the inappropriateness of including discouraged workers or seasonal factors in this definition.
