The following labor demand and supply curves for cashiers in retail stores.
Labor demand curve: E =13 - 1/20 W
Labor supply curve: E =-1 + 1/20 W
a) Show in a table the number of cashier demanded and supply for each wage rate from 3 to 9 euros (increasing by one euro). Plot the supply and demand curves.
b) What are the equilibrium wage and employment levels in this market?
c) Suppose the number of cashiers demanded increases by 30 at every wage rate. Plot the new demand curve. What are the equilibrium wage and employment level now?
