Factors of Production and the Production Possibilities Curve
Read Sections 2.1 and 2.2. Take a moment to read through the stated learning outcomes for this chapter, which you can find at the beginning of each section. These outcomes should be your goals as you read through the chapter. Also, attempt the "Try It" problems for each section before checking your answers.The first section of the chapter will introduce you to the four factors of production that are present in the economy: labor, capital, natural resources, and entrepreneurship. Using any two factors of production, you can then learn to construct the production possibility frontier (PPF) in a two plane model. Note the economic implications of the downward slope and the bowed-out shape of the PPF curve. Also, note the meaning of producing on the curve versus inside the curve. Lastly, think about what it means to move along the curve
2.2 The Production Possibilities Curve
Case in Point: The Cost of the Great Depression
The U.S. economy looked very healthy in the beginning of 1929. It had enjoyed seven years of dramatic growth and unprecedented prosperity. Its resources were fully employed; it was operating quite close to its production possibilities curve.
In the summer of 1929, however, things started going wrong. Production and employment fell. They continued to fall for several years. By 1933, more than 25% of the nation’s workers had lost their jobs. Production had plummeted by almost 30%. The economy had moved well within its production possibilities curve.
Output began to grow after 1933, but the economy continued to have vast numbers of idle workers, idle factories, and idle farms. These resources were not put back to work fully until 1942, after the U.S. entry into World War II demanded mobilization of the economy’s factors of production.
Between 1929 and 1942, the economy produced 25% fewer goods and services than it would have if its resources had been fully employed. That was a loss, measured in today’s dollars, of well over $3 trillion. In material terms, the forgone output represented a greater cost than the United States would ultimately spend in World War II. The Great Depression was a costly experience indeed.
