a. In the diagram to the right, draw a demand curve for labor in manufacturing and a male labor supply curve and total (male and female) pre-legislation labor supply curve. Indicate the equilibrium wage (W), the total quantity of labor supplied (Lt), and the quantities of men (Lm) and women (Lw) hired. (Note: men and women are equally qualified for the manufacturing jobs.)
b. Show the effect of the legislation on the equilibrium wage and total quantity supplied of labor.
c. Decide whether each of the following rises, falls, remains the same or changes in an uncertain direction, and explain each decision briefly:
(1) total expenditures (W x Lt) on labor by manufacturing employers:

 

 

(2) total income (W x Lm) received by men:

 

 

(3) total income (W x Lw) received by women:

 

 

2.

Decide whether the following is true or false and explain briefly: "Removal of natural gas price ceilings is likely to cause an increase in supply which could lower prices for consumers."
