Economics 311: Labor Markets, Employment and Wages
Fall 2002
Problem Set #1: Introduction due: Monday, 9/30/2002
1. Employment and Unemployment Calculations
Suppose you have the following labor market data:
Population = 500
Population age 16 years and older and non-institutionalized = 400
Persons employed full or part-time = 200
Persons unemployed and actively seeking work = 20
Persons who have quit seeking work due to lack of success = 10
Part-time workers seeking full-time jobs = 30
a) What is the size of the labor force?
b) Calculate the official unemployment rate.
c) Calculate the labor force participation rate.
2. Unemployment Understatement and Overstatement
Discuss the factors that result in the official unemployment rate understating the true level of economic hardship in the labor market. (Graded for Writing)
3. Unemployment Insurance
Comment on the following statement from Chapter 15 in Ehrenberg and Smith.
"Increasing the level of unemployment insurance benefits will prolong the average length of spells of unemployment. Hence, a policy of raising UI benefit levels is not socially desirable." (Graded for writing.)
Answer Key
1. Employment and Unemployment Calculations
a. Labor Force = Employed + Unemployed (actively seeking employment)
= 200 + 20 = 220
b. Unemployment Rate = (Unemployed ÷ Labor Force) x 100 = (20 ÷ 220) x 100 = 9%
c. Labor Force Participation Rate = (Labor Force ÷ Working Age Population) x 100 = (220 ÷ 400) x 100 = 55%
2. Unemployment: Understatement and Overstatement
The official unemployment rate tends to understate unemployment, particularly during long and deep recessions because it does not count several types of unemployment and underemployment which are especially serious during recessions. First, discouraged workers officially drop out of the labor force when they stop "actively seeking employment." This happens increasingly during recessions as workers get discouraged by the lack of success at finding an acceptable new job.
Second, workers involuntarily working part-time because of the inability of finding full-time employment will be counted as fully employed workers by the BLS. Involuntary part-time employment is expected to be more common during recessions as firms cut back on hours for workers.
Third, workers unable to find employment in the field in which they are trained will also be counted as fully employed as long as they have some kind of employment. They are, however, underemployed if they are not able to use their employment skills to their full extent.
3. Unemployment Insurance
There is evidence that unemployment insurance leads to workers extending the length of their unemployment spell, and, possibly, also intentionally choosing to be unemployed for spells simply to receive unemployment insurance, this does not necessarily lead to labor market inefficiency. It does lead to inefficiency if these workers are simply using
the time to delay job search and take additional paid leisure. This is because these workers could be producing wealth for society if employed. If unemployment insurance is allowing workers the additional time to find employment more suited to their employment skills, however, then unemployment insurance may actually be leading to greater labor market efficiency, since these workers will be more productive when they find the more suitable employment.
