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
Long ago, when the first human beings walked the earth, they produced food by picking leaves or fruit off a plant or by catching an animal and eating it. We know that very early on, however, they began shaping stones into tools, apparently for use in butchering animals. Those tools were the first capital because they were produced for use in producing other goods – food and clothing.
Modern versions of the first stone tools include saws, meat cleavers, hooks, and grinders; all are used in butchering animals. Tools such as hammers, screwdrivers, and wrenches are also capital. Transportation equipment, such as cars and trucks, is capital. Facilities such as roads, bridges, ports, and airports are capital. Buildings, too, are capital; they help us to produce goods and services.
Capital does not consist solely of physical objects. The score for a new symphony is capital because it will be used to produce concerts. Computer software used by business firms or government agencies to produce goods and services is capital. Capital may thus include physical goods and intellectual discoveries. Any resource is capital if it satisfies two criteria:
One thing that is not considered capital is money. A firm cannot use money directly to produce other goods, so money does not satisfy the second criterion for capital. Firms can, however, use money to acquire capital. Money is a form of financial capital. Financial capital includes money and other "paper" assets (such as stocks and bonds) that represent claims on future payments. These financial assets are not capital, but they can be used directly or indirectly to purchase factors of production or goods and services.
