CEA Labor Economics and Human Capital 1 — Questions and Answers
Question 1: According to human capital theory, what is the primary reason workers with more education tend to earn higher wages?
- They have higher innate ability that employers reward
- They have acquired skills and knowledge that increase their productivity (Correct answer)
- They are protected by stronger labor unions
- They benefit from government wage subsidy programs
Correct answer: They have acquired skills and knowledge that increase their productivity
Human capital theory, developed by Becker and Mincer, holds that education raises earnings by increasing worker productivity, not merely through signaling or protection.
Question 2: Efficiency wage theory suggests that firms pay workers above the market-clearing wage primarily because:
- Government regulations mandate minimum wage floors above equilibrium
- Higher wages reduce shirking, lower turnover, and increase worker productivity (Correct answer)
- Union collective bargaining agreements require above-market compensation
- Firms seek to maximize short-run profits by attracting the best applicants
Correct answer: Higher wages reduce shirking, lower turnover, and increase worker productivity
Efficiency wage theory holds that above-equilibrium wages motivate workers to avoid dismissal, reduce costly turnover, and attract higher-quality applicants.
Question 3: A monopsony in the labor market is best characterized by:
- Many competing firms bidding for workers and driving wages toward marginal product
- A single dominant employer with the ability to set wages below the competitive level (Correct answer)
- Multiple unions negotiating collectively against a single large employer
- Perfect competition where each worker is paid exactly their marginal product
Correct answer: A single dominant employer with the ability to set wages below the competitive level
A monopsonist faces an upward-sloping labor supply curve, allowing it to set wages below the competitive equilibrium and employ fewer workers than the socially optimal level.
Question 4: The Mincer earnings equation estimates wages primarily as a function of:
- Geographic location, industry sector, and firm size
- Years of schooling, years of work experience, and experience squared (Correct answer)
- Race, gender, union membership, and occupation
- CEO compensation, stock performance, and employer revenue
Correct answer: Years of schooling, years of work experience, and experience squared
Jacob Mincer's foundational equation regresses log wages on years of schooling, experience, and experience-squared to capture the concave earnings-experience relationship.
Question 5: Compensating wage differentials arise when:
- Government mandates equal pay for equal work regardless of conditions
- Workers receive higher wages to offset undesirable job characteristics such as danger or instability (Correct answer)
- Employers award bonuses tied to individual or firm performance metrics
- Minimum wage laws create floors that raise pay across all occupations
Correct answer: Workers receive higher wages to offset undesirable job characteristics such as danger or instability
Compensating differentials equalize total job attractiveness; workers in hazardous, unpleasant, or unstable jobs command wage premiums that offset the non-monetary costs.
Question 6: The labor force participation rate (LFPR) is defined as:
- The share of employed workers relative to the entire population
- The ratio of the civilian labor force to the civilian non-institutional working-age population (Correct answer)
- The fraction of workers who found employment within the past month
- The proportion of full-time workers relative to part-time workers
Correct answer: The ratio of the civilian labor force to the civilian non-institutional working-age population
LFPR equals the labor force (employed plus unemployed actively seeking work) divided by the civilian non-institutional population, expressed as a percentage.
Question 7: The 'natural rate of unemployment' refers to:
- The unemployment rate observed only during economic recessions
- The unemployment rate consistent with stable inflation, comprising frictional and structural unemployment (Correct answer)
- The percentage of workers who have permanently exited the labor force
- The minimum unemployment rate achievable through full government employment programs
Correct answer: The unemployment rate consistent with stable inflation, comprising frictional and structural unemployment
The natural rate (NAIRU) is the rate at which inflation neither accelerates nor decelerates, composed of unavoidable frictional and structural unemployment.
