So, ask yourself, how many hours would you be willing to work for $2 an hour? Probably not many. When you think of other ways you could spend your time, a $2 wage probably isn't enough to lure you away from the other alternatives, such as an afternoon at the beach. Or, put differently, the opportunity cost is too high. But, what if you were offered $10 an hour? Now you'd probably be willing to give up other opportunities and work a few, or more than a few, hours. But what if you were offered $50 an hour? Now you'd probably be willing to forgo other alternatives and work as many hours as you could. Like most people, you are far more likely to work more hours at a higher wage than at the lower wage. This is called the substitution effect and explains why the labor supply curve is upward sloping: Workers are willing to work a greater quantity of hours at higher wages than at lower wages.
Again, like other markets, the demand for labor and the supply of labor interact and result in an equilibrium price. In this case the price is called a wage. And, like other markets, the demand for labor and the supply of labor shift, which can cause wages to increase and decrease.
What causes the demand for labor to shift? The demand for labor is derived from – or determined by – the demand for goods and services produced. For example, the demand for nurses is determined by the demand for healthcare services. If the demand for healthcare services increased dramatically, the demand for nurses to provide those services would increase. In such a case, the demand curve would shift to the right and wages for nurses would increase.
On the other hand, if the demand for healthcare services were to decrease, the demand for nurses would decrease as well. The demand curve would shift to the left and wages for nurses would stagnate or even decline over time.
The supply of labor in the labor market is determined by the number of workers who are willing to provide that labor. One factor that affects the number of workers in given professions is the comparative attractiveness of jobs. For example, if higher wages or better working conditions make nursing more attractive than other jobs, more people may be willing to work in nursing, which would shift the supply curve for nursing to the right. This rightward shift would decrease wages for nurses. Likewise, if nursing were to become a less attractive occupation, some nurses would leave for other professions. This decrease in supply would result in higher wages for the nurses who remain.
Another factor that affects the supply of labor is government regulations. For example, say the government were to require nurses to have an additional, more difficult to earn, license. This regulation would decrease the number of nurses able to work at all wage levels. The supply curve for nursing would shift to the left and wages for nurses would increase. On the other hand, if the government were to reduce qualifications or subsidize the training of new nurses, the supply curve would shift to the right and wages would fall.
The laws of supply and demand help explain why some professions pay more highly than others. Economists often separate labor into different markets based on skill levels. So the worker competing for a job at the local fast food restaurant is not competing in the same market with the new medical school graduate. For example, many of the highest paying jobs are in the professional labor market. Jobs in this market, such as for surgeons, require years of highly specialized training. The time, money, and personal skills required for such training tend to restrict the supply of qualified workers willing and able to become surgeons. Also, although the supply of surgeons is small, the services they provide tend to be in relatively high demand. On the other hand, many of the lowest paying jobs, such as those at fast food restaurants, are often in the unskilled labor market. Because these jobs require minimal job skills, there is a large supply of qualified workers. So, in spite of a fairly large demand for fast food, the large supply of workers willing and able to work at fast food restaurants keeps wages low.
Another factor that affects wages is worker productivity. Suppose that two workers produce widgets, but one produces at twice the rate of the other. The more productive worker would be in much greater demand and, as a result, would earn higher wages. Think of it this way, in the competitive labor market, firms compete for the most productive employees because these employees allow firms to earn higher profits. As a result, firms will reward more productive workers with higher wages. If a firm doesn't provide competitive wages, the most productive workers will be hired by another firm willing to pay more. In this way, competition ensures that the wages workers earn reflect their productivity. Workers can increase their productivity—and also their wages—by increasing their skill level and acquiring more education. Numerous studies show a strong positive correlation between education and income. Simply stated, more education usually results in higher income.
So, do you want to earn higher wages? If so, find a profession with high demand but a relatively small supply of qualified providers. Obtain the appropriate education and training for that profession. Then continue your education and training so that you increase your productivity and, as a result, also increase the demand for your services.
