Why is it important to develop your human capital?
When Catherine Winters received a job offer in 2006, the company that wanted to hire her suggested a salary that she was free to accept or reject. How did the company decide how much to offer? How did she decide whether the offer was fair? Both questions could be answered by looking at the wage rates for other, similar positions in the job market. In general, wage rates are determined by the same principle that determines the price of goods and services: supply and demand.
A number of factors influence wage rates. One has to do with the skills and training required for a job. Economists categorize jobs according to four general skill levels.
Unskilled. These jobs require no specialized skills or training. Most workers at this level earn a low hourly wage. Examples of unskilled jobs include janitors, busboys, and seasonal farmworkers.
Semiskilled. Workers at this level have some specialized skills and training, including the ability to use simple tools or equipment. Employees are supervised, and wages are paid on an hourly basis. Jobs include cashiers, construction workers. taxi drivers, and fast food cooks.
Skilled. This level requires specialized skills and training. Workers need little or no supervision, but most are still paid on an hourly basis. Examples include police officers, carpenters, bank tellers, and factory workers who operate complicated machinery.
Professional. This level includes “white collar” jobs that require advanced training and specialized skills. Professional workers receive a salary. Jobs include doctors, lawyers, teachers, airline pilots, and computer specialists.
In general, wages are based on skill level. As skills and training increase, so do wages. More importantly, however, workers command wages that reflect the market value of what they produce. Surgeons are paid more than nurses, for example, because the market places a higher value on surgery than it does on general nursing care. For the same reason, more productive workers tend to receive higher wages than less productive workers. As economist Robert Frank notes, “Workers tend to be paid in rough proportion to the value they add to their employer’s bottom line.”
Competition among employers to hire workers also helps to raise wages. Figure 10.3A illustrates this point by looking at the effect of competition on wages for apple pickers. In this scenario, Farmer A begins the harvest season by paying his apple pickers $7.00 an hour. Farmer B, faced with a shortage of workers, decides to offer S8.00 an hour. Lured by the higher wages, a number of workers leave Farmer A and go to work for Farmer B. As a result of this competition for workers, Farmer A must also raise wages in order to attract and retain new workers.
Farmer A and Farmer B are imaginary, but they illustrate a real dynamic that shapes the labor market: the interaction of supply and demand. Employers create the demand for labor, and workers seeking jobs create the supply. Wages move toward equilibrium in the labor market just as prices move toward equilibrium in the market for goods and services. The demand for labor comes from businesses and government agencies that compete with each other to hire workers. Demand changes over time with the state of the economy. When the economy is doing well, the quantity oflabor demanded goes up, and just as an increased demand for goods tends to raise prices, an increased demand for labor tends to boost wages. In the case of Farmers A and B, competition for apple pickers forced wages up.
Conversely, wages tend to fall when the supply of labor increases or the demand for labor decreases. When the number of people seeking jobs exceeds the quantity demanded, employers can offer lower wages and still find people who are willing to work.
Immigration can play a role in increasing the labor supply and lowering wage rates. In recent decades, competition for jobs from new immigrants has helped to depress wages at the lower end of the labor market. That is one reason why many less skilled workers oppose increased immigration.
The labor supply is also affected by the tradeoff between work and leisure. When wages are low, people may be less inclined to work and more inclined to pursue other activities. When wages are high, however, workers tend to sacrifice leisure activities in favor of work.
In making such decisions, people are following the costs-versus-benefits principle. For example, suppose you plan to spend time with your friends one afternoon when a neighbor offers you a job cleaning her garage. If she were to offer $5 for an afternoon of work, you would probably say no. But if she were to offer $100, you would probably take the job. In this case, the benefit of earning $100 would outweigh the cost of not seeing your friends.
Over time, wages tend to move toward equilibrium, the point at which the quantity of labor demanded equals the quantity of labor supplied. An equilibrium wage is a wage rate that results in neither a surplus nor a shortage of qualified workers.
If the wage for a job is too high, a surplus of workers will apply for the job and employers will lower the wage. If the wage is too low, too few people will apply, and the wage will have to rise to attract more workers. Only when the wage reaches equilibrium will demand and supply be in balance.
The graphs in Figure 10.3B show equilibrium wages for two occupations: lawyer and security guard. The wages for these jobs differ for two main reasons. First, the skill level and training required of lawyers is much greater than that required of security guards. Lawyers invest a great deal of time and money in their education. Therefore the supply of lawyers is smaller than the supply of security guards. The second reason is that lawyers perform a higher-value service than security guards do. People are willing to pay more for a lawyer than a security guard. Since the lawyer’s labor is more highly valued, the labor warrants a higher wage.
A number of other factors can also affect wages, including minimum wage laws, working conditions, and cost of living.
Minimum wage laws. Minimum wage laws passed by the federal and state governments can raise wages for low-skill jobs above the equilibrium level. State minimum wage rates vary and may differ from the federal rate. Most workers qualify for the minimum wage, but exceptions exist. Workers who do not qualify include people who are self-employed, such as babysitters and newspaper carriers, and the employees of very small businesses. Around half of all Americans who earn the minimum wage are young workers between the ages of 16 and 24.
Working conditions. Jobs with working conditions that are uncomfortable, stressful, or dangerous may also pay higher wages than less-demanding jobs at similar skill levels. For example, Alaskan crab-fishing crews earn more than fishing crews elsewhere. in part because working conditions are so dangerous in the seas off Alaska. Similarly, air traffic controllers work under highly stressful conditions and receive relatively high wages to compensate for that stress.
Location and cost of living. In some parts of the United States, employers may be willing to pay extra to attract qualified workers. A rural hospital, for example, may pay doctors more than a city hospital because the remote location limits the supply of doctors.
The cost of living in a region also affects wages. Living costs in California, for example, are higher than in Louisiana. Wages reflect this difference. For example, software engineers in California made an average of around $99,000 in 2013, compared to just over $76,000 for software engineers in Louisiana.
Rising cost of fringe benefits. The cost of fringe benefits also affects wages. Fringe benefits are nonwage compensations offered to workers in addition to their pay. Typical benefits include health insurance, paid vacation time, and retirement plans.
The cost of such benefits has risen in recent years. Health insurance in particular has become increasingly expensive. In 1980, employers nationwide spent about $60 billion on private health insurance for their workers. In 2010, employers spent over $560 billion on private health insurance. These rising costs have helped to depress wages in some industries, as employers compensate for high health care costs by holding down wages.
Foreign competition. Competition for jobs in the global market also helps to depress wages. As more companies offshore key tasks to low-wage countries, wage rates in the United States face downward pressure. For example, many American furniture manufacturers now offshore production to low-wage countries such as China. Faced with factory closings, furniture workers in the United States may agree to accept lower wages in order to keep their jobs.
Historically, wages have also been influenced by discrimination against certain groups in society. Wage discrimination occurs when some workers are paid less to do the same job as other workers because of their ethnicity, gender, or other personal characteristics.
The Civil Rights Act of 1964 outlawed discrimination based on gender, race, religion, and country oforigin. Nevertheless, a wage gap — a difference in the wages earned by different groups in society — still exists. For example, since 1964, the wage gap between men and women has narrowed, but women earn only about four-fifths of what men earn. In 2012, the median weekly income for white men working fulltime was $879. For white women, the figure was $710.
A gender-based wage gap exists in every group surveyed: Asian American, white, African American, and Hispanic. Wage gaps also exist among the four groups, with Asian Americans earning the highest median salaries and Hispanics the lowest.
If discrimination is illegal, why does the wage gap persist’ Economists attribute it in part to different levels of human capital among different groups. For example, African Americans, on average, have less education than Whites and Asians. This education gap is itself a legacy of discrimination that denied blacks equal access to education for many years. Women, on average, have less job experience than men. This “experience gap” exists in part because women have only entered the labor force in large numbers in recent decades. Women are also more likely to interrupt their careers to raise children.
Even though differences in human capital contribute to the wage gap, studies show that discrimination still exists in the labor market. Many economists contend that the remedy for this problem is market competition. They argue that firms that discriminate will not be able to compete in the long run because they do not take advantage of the whole pool of qualified workers. Firms that do not discriminate will be more profitable than those that do.
Nevertheless, there are limits to the power of market forces to end discrimination. The United States has antidiscrimination laws to help fill the gap. Affirmative action initiatives are also intended to prevent discrimination. These initiatives call on employers to take positive steps to increase the presence of historically underrepresented groups in employment, education, and business.
Affirmative action policies have aroused controversy, This is especially true for policies that give preferential treatment to women and minorities. This type of affirmative action has come under attack from critics who say it discriminates against white males. In a series of landmark cases, the U.S. Supreme Court has narrowly upheld affirmative action in such areas as college admissions. However, the debate continues as to whether affirmative action is the appropriate means to achieve equal opportunity for all.
