Questions: Unemployment Theory

Question 1

Frictional unemployment exists because...

• A. Workers are too lazy to find jobs
• B. Matching workers with appropriate jobs takes time due to information frictions, even when suitable jobs exist
• C. The government deliberately creates unemployment through regulation
• D. There are never enough jobs for all workers

Answer: (B)

Frictional unemployment reflects the time-consuming process of job search and matching. Even in a booming economy with abundant vacancies, workers need time to learn about opportunities, apply, interview, and negotiate. Workers who quit to find better matches, recent graduates entering the labor force, and workers between seasonal jobs all contribute to frictional unemployment. It is an unavoidable consequence of a dynamic economy where jobs are constantly being created and destroyed.

Question 2

The NAIRU is a constant that does not change over time.

• T. True
• F. False

Answer: False

The NAIRU is not a fixed natural constant — it varies with structural features of the labor market. Changes in matching efficiency (due to technology like online job boards), unemployment insurance generosity, demographic composition of the workforce (younger workers have higher turnover rates), occupational mismatch, and labor market institutions all shift the NAIRU over time. The US NAIRU has varied from roughly 6% in the 1980s to below 4% in the 2020s, partly reflecting improved matching technology and demographic shifts.

Question 3

What is the difference between structural and cyclical unemployment, and why does the distinction matter for policy?

Model answer: Structural unemployment results from mismatch between available workers and available jobs (skills, geography, industry) and persists even in strong economies. Cyclical unemployment results from insufficient aggregate demand and fluctuates with the business cycle. The distinction matters because the appropriate policy responses differ: cyclical unemployment responds to demand-side policies (monetary and fiscal stimulus), while structural unemployment requires supply-side interventions (retraining programs, relocation assistance, education reform). Using demand stimulus to address structural unemployment risks inflation without reducing unemployment.

Distinguishing the two in real time is extremely difficult because structural and cyclical factors often coexist. During the Great Recession, some argued that high unemployment was structural (workers' skills did not match available jobs) while others argued it was primarily cyclical (insufficient demand). The distinction had enormous policy stakes: if structural, fiscal stimulus would produce inflation without reducing unemployment; if cyclical, austerity would be counterproductive. Evidence — including stable wage growth and broad-based unemployment across sectors — eventually supported the primarily cyclical interpretation.
