1 16.1 THE ANATOMY OF FACTOR MARKETS 16.1 THE ANATOMY OF FACTOR MARKETS
The four factors of production that produce goods and Factor price services are: The price of a factor of production. • Labor • The wage rate is the price of labor. • Capital • The interest rate is the price of capital. • Land • Rent is the price of land. • Entrepreneurship Factor market A market for labor, capital, or land.

Bond Market Land Markets
A bond market is a market in which bonds issued by Land consists of all the gifts of nature. firms or governments are traded. The markets for raw materials are called commodity Bond markets. A promise to pay specified sums of money on specified dates. Competitive Factor Markets Most factor markets have many buyers and sellers and are competitive markets.

Derived demand Value of Marginal Product The demand for a factor of production, which is Table 16.1 on the next slide walks you through the derived from the demand for the goods and services it calculation of the value of marginal product. is used to produce. Value of marginal product The value to a firm of hiring one more unit of a factor of production, which equals price of a unit of output multiplied by the marginal product of the factor of production.

Figure 16.1 shows the value of the marginal product at Max’s Wash’n’ Wax. The blue bars show the value of the marginal product of the labor that Max hires based on the numbers in the table.

If the wage rate exceeds the value of marginal product of labor, a firm can increase its profit by employing one fewer worker.

Figure 16.2 shows the demand for labor at Max’s Wash’n’ Wax. The demand for labor curve At a wage rate of $10.50 an hour, Max makes a profit on the slopes downward because the first 2 workers but would incur a value of the marginal product of labor diminishes as the quantity loss on the third worker. of labor employed increases. So Max’s quantity of labor demanded is 2 workers. Max’s demand for labor curve is the same as the value of marginal product curve.

Changes in the Demand for Labor The Price of the Firm’s Output The demand for labor depends on: The higher the price of a firm’s output, the greater is • The price of the firm’s output its demand for labor. • The prices of other factors of production The Prices of Other Factors of Production • Technology If the price of using capital decreases relative to the wage rate, a firm substitutes capital for labor and increases the quantity of capital it uses. Usually, the demand for labor will decrease when the price of using capital falls.
16.2 DEMAND IN FACTOR MARKET 16.3 WAGES AND EMPLOYMENT
Technology The Supply of Labor New technologies decrease the demand for some People supply labor to earn an income. Many factors types of labor and increase the demand for other influence the quantity of labor that a person plans to types. provide, but the wage rate is a key factor. Figure 16.3 on the next slide shows an individual’s labor supply curve.

16.3 WAGES AND EMPLOYMENT 16.3 WAGES AND EMPLOYMENT
In a market for Influences on the Supply of Labor a specific type Three key factors influence the supply of labor: of labor, the quantity • Adult population supplied increases as • Preferences the wage rate increases, other • Time in school and training things remaining the same.

Adult Population Time in School and Training An increase in the adult population increases the The more people who remain in school for full-time supply of labor. education and training, the smaller is the supply of low-skilled labor. Preferences There has been a large increase in the supply of female labor since 1960. The percentage of men with jobs has shrunk slightly.

Labor Market Equilibrium Labor market equilibrium determines the wage rate and employment. 1. The equilibrium wage Figure 16.5 on the next slide illustrates equilibrium in rate is $10.50 an hour. the market for car wash workers. 2. The equilibrium quantity of labor is 300 workers.
10 16.3 WAGES AND EMPLOYMENT
If the wage rate exceeds $10.50 an hour, the Chapter quantity demanded is less than the quantity supplied The End and the wage rate falls. 16 If the wage rate is below $10.50 an hour, the quantity demanded exceeds the quantity supplied and the wage rate rises. Copyright © 2002 Addison Wesley

The higher the interest rate, the greater is the quantity The quantity of physical capital that a firm plans to use of saving supplied. depends on the price of financial capital - the interest The main influences on the supply of saving are: rate. • Population Two factors that change the demand for captial are: • Average income • Population growth • Expected future income • Technological change

Financial Market Equilibrium and the The demand for financial Interest Rate capital is KD, and the supply of financial capital is Financial market equilibrium occurs when the interest KS. rate has adjusted to make the quantity of capital demanded equal the quantity of capital supplied. 1. The equilibrium interest rate is 6 percent a year. Figure 16.6 on the next slide illustrates financial market equilibrium. 2. The equilibrium quantity of financial capital is $200 billion.
16.5 LAND AND NATURAL RESOURCES 16.5 LAND AND NATURAL RESOURCES
All natural resources are called land, and they fall into The Market for Land (Renewable Natural two categories: Resources) • Renewable The lower the rent, the greater is the quantity of land • Nonrenewable demanded. Renewable natural resources The supply of a particular block of land is perfectly Natural resources that can be used repeatedly. inelastic. Nonrenewable natural resources Figure 16.7 illustrates this market for land. Natural resources that can be used only once and that cannot be replaced once they have been used.
