The reverse is also true: the U.S. has a lower opportunity cost of producing wheat than Brazil. Production totals 350 pairs of skis per month and zero snowboards. Think about what life would be like without specialization. Had the firm based its production choices on comparative advantage, it would have switched Plant 3 to snowboards and then Plant 2, so it would have operated at point C. It would be producing more snowboards and more pairs of skisand using the same quantities of factors of production it was using at B. The gains we achieve through specialization are enormous. Clearly not. Where will it produce them? We will see in the chapter on demand and supply how choices about what to produce are made in the marketplace. Economists often use models such as the production possibilities model with graphs that show the general shapes of curves but that do not include specific numbers. In this section, we shall assume that the economy operates on its production possibilities curve so that an increase in the production of one good in the model implies a reduction in the production of the other. b. used efficiently. Suppose further that all three plants are devoted exclusively to ski production; the firm operates at A. To see this relationship more clearly, examine Figure 2.3 The Slope of a Production Possibilities Curve. In an actual economy, with a tremendous number of firms and workers, it is easy to see that the production possibilities curve will be smooth. We will make use of this important fact as we continue our investigation of the production possibilities curve. The table in Figure 2.2 A Production Possibilities Curve gives three combinations of skis and snowboards that Plant 1 can produce each month. Our mission is to improve educational access and learning for everyone. The negative slope of the production possibilities curve reflects the scarcity of the plants capital and labor. 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.

It illustrates the production possibilities model. As you read this section, focus on the similarities. First, the economy might fail to use fully the resources available to it. It suggests that to obtain efficiency in production, factors of production should be allocated on the basis of comparative advantage. When government spends a certain amount more on reducing crime, for example, the original increase in opportunity cost of reducing crime could be relatively small. This is because its slope is given by the relative prices of the two goods, which from the point of view of an individual consumer, are fixed, so the slope doesn't change. That's the trade-off this society faces. Now consider the other end, at the lower right, of the production possibilities frontier. Producing 100 snowboards at Plant 2 would leave Alpine Sports producing 200 snowboards and 200 pairs of skis per month, at point C. If the firm were to switch entirely to snowboard production, Plant 1 would be the last to switch because the cost of each snowboard there is 2 pairs of skis. To understand why the PPF is curved, start by considering point A at the top left-hand side of the PPF. Thats the trade-off this society faces. Of course, an economy cannot really produce security; it can only attempt to provide it. The following graph illustrates these ideas using a production possibilities frontier between healthcare and education. It is hard to imagine that most of us could even survive in such a setting. Just as individuals cannot have everything they want and must instead make choices, society as a whole cannot haveeverything it might want, either. It need not imply that a particular plant is especially good at an activity. This can be illustrated by the PPFs of the two countries in the following graphs. A production possibilities curve is a graphical representation of the alternative combinations of goods and services an economy can produce. According to this law, with the fuller utilisation of the given resources, in order to produce an additional unit of one good, some of the resources are to be withdrawn from the production of another good. It can shift to ski production at a relatively low cost at first. For example, after not spending much at all on crime reduction, when a government spends a certain amount more, thegains in crime reduction could be relatively large.
