The following information is to be used for calculations of the unemployment rate: Suppose there are only two major groups, adults and teenagers, with adults divided into men and women.
Teenagers account for 10 percent of the labor force; adults account for 90 percent. Women make up 35 percent of the adult labor force. Suppose also that the unemployment rates for these groups are as follows: Teenagers, 19 percent; men, 7 percent; and women, 6 percent.

Teenagers account for 10 percent of the labor force; adults account for 90 percent. Women make up 35 percent of the adult labor force. Suppose also that the unemployment rates for these groups are as follows: Teenagers, 19 percent; men, 7 percent; and women, 6 percent.
(a) The aggregate unemployment rate can be calculated by adding the unemployment rates of different groups weighted by their share of the labor force.
Given share to labor force
Teenagers= 10%
Adult workforce= 90%
Further adults divided into males and females.
Females= 35%
Males= 65%
So aggerate unemployment rate
u=(0.1)(0.19)+(0.9)[(0.35)(0.06)+(0.65)(0.07)]
=0.019+(0.19)(0.021+0.0455)
=0.019+0.05985=0.07885
=7.9%
(b) Since labor force of teenagers increase from 10% to 15%. Then aggregate unemployment also changes
u1=(0.15)(0.19)+(0.85)[(0.35)(0.06)+(0.65)(0.07)]
=0.0285+(0.85)(0.021+0.0455)
=0.0285+0.056525= 0.085025
=8.5%
