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
An economy that is operating inside its production possibilities curve could, by moving onto it, produce more of all the goods and services that people value, such as food, housing, education, medical care, and music. Increasing the availability of these goods would improve the standard of living. Economists conclude that it is better to be on the production possibilities curve than inside it.
Two things could leave an economy operating at a point inside its production possibilities curve. First, the economy might fail to use fully the resources available to it. Second, it might not allocate resources on the basis of comparative advantage. In either case, production within the production possibilities curve implies the economy could improve its performance.
