 1. Given the original supply and demand curves in Table 1 (LD0 and LS0), do the following:

 

a. Find the equilibrium wage and quantity of labor hired.

 

b. Calculate the total earnings of labor (TE) in this market.

 

c. Graph this situation and label all of the points described above.

 

d. What situation occurs when the wage is $26? Explain how the market adjusts back to equilibrium when the wage is $26.

 

NOTE: Show all work for sections requiring calculations.

 

2.   Using the numbers in Table 1, start with the equilibrium established with LD0 and LS0, draw the indicated shift in demand or supply, and briefly explain your graph. Then repeat 1.a. through 1.c. for the following:

 

a. There is a decrease in demand for steel as producers use aluminum instead of steel in their cans.

 

b. Legislation preserving the spotted owl reduces the supply of lumber and increases its price. As a consequence, many home-builders begin using structural steel frames to construct homes.

 

c. Because younger workers see better possibilities elsewhere, the number of retiring steelworkers exceeds the number of new steelworkers.

 

d. Unions negotiated a number of "givebacks" in the early 1980s which lowered the wages of steelworkers from $26 to $22. (Note: Unions will generally set wages above those set by the market because they have market power. Givebacks mean that unions are willing to lower wages to save jobs even though these lower wages are still above those set by the market.)

 

 3. Using the numbers in Table 1, start with the equilibrium established with LD0 and LS0 and do the following:

 

a. The government establishes a minimum wage for unskilled workers at $24. Draw this on a graph and briefly explain how this minimum wage will affect this labor market.

 

b. Calculate the welfare loss associated with the minimum wage and indicate the welfare loss on the graph. Briefly explain what a welfare loss is.

 

c. Graph and explain what happens when the minimum wage is raised to $26. What happens to the welfare loss? Explain.

 

 

d. Graph and explain what happens to minimum wage workers in a recession. Then compare this result to what happens to workers who are not affected by the minimum wage.

 4. Given the numbers in Table 2, do the following:

 

a. Graph the supply and demand for the taxed sector and label all relevant points with numbers.

 

b. A tax of $4 per worker is levied on employers. Place the proper numbers in the row for LD1 and draw a new graph with this tax on it. Be sure to label the new equilibrium.

c. Extra Credit: Calculate the final burden for employer and worker and indicate each area on the graph.

 

d. Calculate the welfare loss and explain how it arose.

 

e. Graph the supply and demand curves for the untaxed sector and label all relevant points with numbers.

 

f. Show and explain what happens in the untaxed sector when those workers who were displaced by the tax attempt to find jobs in that sector. Fill in the second part of Table 2 for the new supply curve and label the new equilibrium.
