Wages: Factors That Affect Wage Levels and Wage Determination under Pure Competition
Most people work to earn a living, which they do by supplying their labor in return for money. Laborers consist of unskilled workers, blue and white collar workers, professional people, and small business owners.
Wages are the price that workers receive for their labor in the form of salaries, bonuses, royalties, commissions, and fringe benefits, such as paid vacations, health insurance, and pensions. The wage rate is the price per unit of labor. Most commonly, workers are paid by the hour. For instance, in 2011, the legal minimum wage rate for most employees in the United States is $7.25 per hour. Earnings equals the wage rate multiplied by the number of hours worked, so an employee earning minimum wage and working the typical 40-hour week earns $7.25 × 40 = $290 per week = $15,080 per year.
Nominal wage is the amount earned in terms of dollars or other currency, while the real wage is the amount earned in terms of what it can actually buy. If the nominal wage does not increase as much as the inflation rate, then real wages decline.
Wages differ among nations, regions, occupations, and individuals. Generally, wages will be higher where the demand for labor is greater than the supply. Nominal wages vary more than real wages, since the purchasing power of different currencies varies considerably. For instance, in countries with low-priced labor, such as China and India, household goods and services have lower prices than in more advanced economies.
The main factor that determines the upper limits of wages is the productivity of the business in combining inputs to produce socially desirable outputs. Obviously, more productive workers can be paid more. Productivity largely depends on the availability of real capital, in the form of machinery and automation, and on the availability of natural resources, which are required as inputs in the production of products and services.
The amount of education or training also largely determines how much a worker can earn, not only by making the worker more productive but by also making the worker more desirable to employers, who compete for workers through the level of wages that they offer. If the time required for training or education is long, then it must lead to higher paying jobs; otherwise, people would pursue easier work or work that can be attained in less time if there was no difference in pay.
The quality of the entrepreneurs who start a business will also determine the efficiency of the business since they lay down the initial organization of how the business will be conducted to produce its output from its various inputs. Afterwards, the quality of the management will affect the efficiency of the business, and therefore, the workers, by how effectively they control costs and produce the desired output.
Another factor affecting productivity is the political and social environment of the country or region in which the business is located. Many governments, especially in corrupt countries, interfere with the development of businesses or try to extract payments, in the form of bribes, from businesses for the enrichment of particular people in the government rather than using it as tax revenue for the benefit of society. In the same way that mismanagement can reduce the efficiency of workers in a business, the mismanagement of a country can likewise reduce the efficacy of its people. Many businesses that are unionized are often less productive, since they are constrained by the demands of the union or by union contracts. For instance, unions often resist automation, and other cost-saving changes to project jobs. The size of the market also matters. Larger markets can help promote efficiency in that economies of scale can be reached.
Wage Determination under Pure Competition
A purely competitive labor market exists when:
- many firms compete for specific labor;
- the laborers have identical skills;
- both the firms and the workers are wage takers, since neither can influence the wage rate;
- there are no unions, since union wages are generally not the result of market supply and demand.
The market demand for labor is for a specific type of labor and not necessarily for a specific industry. If one industry paid more than another for a specific type of labor, then more laborers would work for that industry until the wages are equalized.
