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
The production possibilities curves for the two plants are shown, along with the combined curve for both plants. Plant R has a comparative advantage in producing calculators. Plant S has a comparative advantage in producing radios, so, if the firm goes from producing 150 calculators and no radios to producing 100 radios, it will produce them at Plant S. In the production possibilities curve for both plants, the firm would be at M, producing 100 calculators at Plant R.
