Chapter 19: Problem 6

A New York Times article observed that the wage of farmworkers in Mexico was \(\$ 11\) an hour but the wage of immigrant Mexican farmworkers in California was \(\$ 9\) an hour. a. Assume that the output sells for the same price in the two countries. Does this imply that the marginal product of labor of farmworkers is higher in Mexico or in California? Explain your answer, and illustrate with a diagram that shows the demand and supply curves for labor in the respective markets. In your diagram, assume that the quantity supplied of labor for any given wage rate is the same for Mexican farmworkers as it is for immigrant Mexican farmworkers in California. b. Now suppose that farmwork in Mexico is more arduous and more dangerous than farmwork in California. As a result, the quantity supplied of labor for any given wage rate is not the same for Mexican farmworkers as it is for immigrant Mexican farmworkers in California. How does this change your answer to part a? What concept best accounts for the difference between wage rates for Mexican farmworkers and immigrant Mexican farmworkers in California? c. Illustrate your answer to part b with a diagram. In this diagram, assume that the quantity of labor demanded for any given wage rate is the same for Mexican employers as it is for Californian employers.

Question: Explain the difference in the marginal product of labor between farmworkers in Mexico and immigrant Mexican farmworkers in California accounting for factors like working conditions and market supply and demand. Answer: The difference in the marginal product of labor between farmworkers in Mexico and immigrant Mexican farmworkers in California can be attributed to factors like working conditions and differences in the supply and demand for labor in these markets. Due to the more arduous and dangerous nature of farmwork in Mexico, the supply of labor may be lower, leading to a compensating differential and higher wage rate of \(\$11\) per hour compared to \(\$9\) for immigrant Mexican farmworkers in California. This difference in wages suggests a higher marginal product of labor in Mexico compared to immigrant Mexican farmworkers in California.

Step by step solution

01

Determine the relationship between marginal product of labor and wages

According to economic theory, the wage rate in any type of market is equal to the marginal product of labor in that specific market, i.e., the additional output produced by hiring one more worker. If a worker’s marginal product is higher, firms demand that worker at a higher wage rate. Knowing this, we can compare the marginal product of labor in Mexico and in California by analyzing the wages in both labor markets.
02

Compare marginal product of labor between Mexico and California (part a)

We are given that the wage of farmworkers in Mexico is \(\$11\) an hour, while the wage of immigrant Mexican farmworkers in California is \(\$9\) an hour. Assuming that the output sells for the same price in the two countries and the quantity supplied of labor for any given wage rate is the same for Mexican farmworkers as it is for immigrant Mexican farmworkers in California, we can infer that the marginal product of labor is higher in Mexico (MP(Labor Mexico) > MP(Labor California)).
03

Analysis of more arduous and dangerous farmwork in Mexico (part b)

Due to the more arduous and dangerous nature of farmwork in Mexico as opposed to farmwork in California, the quantity supplied of labor for any given wage rate will not be the same for Mexican farmworkers as it is for immigrant Mexican farmworkers in California. This means that the demand for labor may be higher in Mexico, but the supply of labor may be lower, leading to similar wage rates. In this case, the concept of compensating differentials can best account for the difference in wage rates between Mexican farmworkers and immigrant Mexican farmworkers in California. Compensating differentials are differences in wages offered for jobs that require the same skill level but may have different working conditions or inconveniences associated with them.
04

Illustrate the answer with a diagram (part c)

To illustrate this answer, we will draw the supply and demand curves for Mexican farmworkers and immigrant Mexican farmworkers in California, assuming that the quantity of labor demanded for any given wage rate is the same for these markets. Imagine a graph where the vertical axis represents the wage rate (W) and the horizontal axis represents the quantity of labor (L). For California labor market, we have a downward-sloping Demand curve (D) and an upward-sloping Supply curve (S). At the equilibrium, the wage rate for immigrant Mexican farmworkers in California is \(\$9\). For the Mexican labor market, we have a similar Demand curve (D') and an upward-sloping Supply curve (S'). However, due to the more arduous and dangerous nature of farmwork in Mexico, the supply curve shifts to the left, indicating a lower quantity of labor supplied at each wage rate. At the equilibrium, the wage rate for Mexican farmworkers is \(\$11\). This illustrates that the difference in wage rates between the two markets can be explained by factors such as the more arduous and dangerous nature of farmwork in Mexico, which results in a compensating differential as the supply of labor is lower in this market.

You are the governor's economic policy adviser. The governor wants to put in place policies that encourage employed people to work more hours at their jobs and that encourage unemployed people to find and take jobs. Assess each of the following policies in terms of reaching that goal. Explain your reasoning in terms of income and substitution effects, and indicate when the impact of the policy may be ambiguous. a. The state income tax rate is lowered, which has the effect of increasing workers' after-tax wage rate. b. The state income tax rate is increased, which has the effect of decreasing workers' after-tax wage rate. c. The state property tax rate is increased, which reduces workers' after-tax income.

Kendra is the owner of Wholesome Farms, a commercial dairy. Kendra employs labor, land, and capital. In her operations, Kendra can substitute between the amount of labor she employs and the amount of capital she employs. That is, to produce the same quantity of output she can use more labor and less capital; similarly, to produce the same quantity of output she can use less labor and more capital. Let \(w^{*}\) represent the annual cost of labor in the market, let \(r_{L}^{*}\) represent the annual cost of a unit of land in the market, and let \(r_{K}^{*}\) represent the annual cost of a unit of capital in the market. a. Suppose that Kendra can maximize her profits by employing less labor and more capital than she is currently using but the same amount of land. What three conditions must now hold for Kendra's operations (involving her value of the marginal product of labor, land, and capital) for this to be true? b. Kendra believes that she can increase her profits by renting and using more land. However, if she uses more land, she must use more of both labor and capital; if she uses less land, she can use less of both labor and capital. What three conditions must hold (involving her value of the marginal product of labor, land, and capital) for this to be true?

In 2013, national income in the United States was \(\$ 14,542.4\) billion. In the same year, 137 million workers were employed, at an average wage, including benefits of \(\$ 64,667\) per worker per year. a. How much compensation of employees was paid in the United States in 2013 ? b. Analyze the factor distribution of income. What percentage of national income was received in the form of compensation to employees in \(2013 ?\) c. Suppose that a huge wave of corporate downsizing leads many terminated employees to open their own businesses. What is the effect on the factor distribution of income? d. Suppose the supply of labor rises due to an increase in the retirement age. What happens to the percentage of national income received in the form of compensation of employees?

Jameel runs a driver education school. The more driving instructors he hires, the more driving lessons he can sell. But because he owns a limited number of training automobiles, each additional driving instructor adds less to Jameel's output of driving lessons. The accompanying table shows Jameel's production function per day. Each driving lesson can be sold at \(\$ 35\) per hour. Determine Jameel's labor demand schedule (his demand schedule for driving instructors) for each of the following daily wage rates for driving instructors: \(\$ 160, \$ 180,\) \(\$ 200, \$ 220, \$ 240,\) and \(\$ 260\)

For each of the following situations in which similar workers are paid different wages, give the most likely explanation for these wage differences. a. Test pilots for new jet aircraft earn higher wages than airline pilots. b. College graduates usually have higher earnings in their first year on the job than workers without college degrees have in their first year on the job. c. Full professors command higher salaries than assistant professors for teaching the same class. d. Unionized workers are generally better paid than non-unionized workers.
