(a)
Determine the number of workers of each race that a non-discriminating firm would hire and the amount of profit earned if there are no other costs.
(a)

Explanation of Solution
If a firm is non-discriminating, then it will hire all black workers as labor enters the function of the marginal product as a sum and black wage is lower than the white wage. Therefore, the firm will prefer to hire black workers Therefore, the number of worker can be calculated as follows:
Rearrange Equation 1 as follows:
Use Equation 2, to get the value of
Thus,
Substitute the value of
Since firm prefer black workers, it is assumed that
Therefore, the non-discriminate firm hires 15 black workers and 0 white workers. Substitute the value into the production Function (given in the question).
Thus, the output is approximately 111.
Therefore, the profit can calculate as follows:
Thus, the profit earned is $1,470.
(b)
Determine the number of workers of each race that a firm with discrimination coefficient of 0.6 against blacks would hire and the amount of profit earned if there are no other costs.
(b)

Explanation of Solution
Here, the discriminating firm is associated with a discrimination coefficient of 0.6. This coefficient will compare the white wage of $100 to the adjusted black wage of $80
Using the similar method explained in part “a”, the number of workers can be calculated as follows:
Rearrange Equation 3 as follows:
Use Equation 4, to get the value of
Thus,
Substitute the value of
For simplicity, it is assumed that
Therefore, the discriminate firm hires 9 black workers and 0 white workers. Substitute the value into the production Function (given in the question).
Thus, the output is approximately 88.
Therefore, the profit can be calculated as follows:
Thus, the profit earned is $1,310.
(c)
Determine the number of workers of each race that a firm with discrimination coefficient of 1.2 against blacks would hire and the amount of profit earned if there are no other costs.
(c)

Explanation of Solution
Here, the discriminating firm is associated with a discrimination coefficient of 1.2. This coefficient will compare the white wage of $100 to the adjusted black wage of $100
Using the similar method explained above, the number of workers can be calculated as follows:
Rearrange Equation 5 as follows:
Use Equation 6, to get the value of
Thus,
Substitute the value of
For simplicity, it is assumed that
Therefore, the discriminate firm hires 7 white workers and 0 black workers. Substitute the value into the production Function (given in the question):
Thus, the output is approximately 78.
Therefore, the profit can be calculated as follows:
Thus, the profit earned is $860.

A town relies on four different sources for its non-drinking water needs: dam water, reclaimed water, rain water, and desalinated water. The different sources carry different risks and costs. For instance, desalinated water is fully reliable due to abundant sea water, but it is more expensive than other options. Reclaimed water also has relatively lower risk than rain or dam water since a certain amount can be obtained, even during the dry. season, by the treatment of daily generated waste water. Using any of the four options requires an investment in that resource. The return on a particular water source is defined as the amount of water generated by the source per dollar of investment in it. The expected returns and standard deviations of those returns for the four water sources are described in the following table: Water resource Expected return St. Deviation Dam water 2.7481 0.2732 Reclaimed water 1.6005 0.0330 Rain water 0.5477 0.2865 Desalinated water 0.3277 0.0000 Higher…arrow_forward1. Imagine a society that produces military goods and consumer goods, which we'll call "guns" and "butter." a. Draw a production possibilities frontier for guns and butter. Using the concept of opportunity cost, explain why it most likely has a bowed-out shape. b. Show a point that is impossible for the economy to achieve. Show a point that is feasible but inefficient. c. Imagine that the society has two political parties, called the Hawks (who want a strong military) and the Doves (who want a smaller military). Show a point on your production possibilities frontier that the Hawks might choose and a point the Doves might choose. d. Imagine that an aggressive neighboring country reduces the size of its military. As a result, both the Hawks and the Doves reduce their desired production of guns by the same amount. Which party would get the bigger "peace dividend," measured by the increase in butter production? Explain.arrow_forward
