## 经济代写|微观经济学代考Microeconomics代写|A PARABLE FOR THE MODERN ECONOMY

To understand why people choose to depend on others for goods and services and how this choice improves their lives, let’s look at a simple economy. Imagine that there are two goods in the world-meat and potatoes. And there are two people in the world-a cattle rancher and a potato farmer-each of whom would like to eat both meat and potatoes.

The gains from trade are most obvious if the rancher can produce only meat and the farmer can produce only potatoes. In one scenario, the rancher and the farmer could choose to have nothing to do with each other. But after several months of eating beef roasted, boiled, broiled, and grilled, the rancher might decide that self-sufficiency is not all it’s cracked up to be. The farmer, who has been eating potatoes mashed, fried, baked, and scalloped, would likely agree. It is easy to see that trade would allow them to enjoy greater variety: Each could then have a hamburger with french fries.

Although this scene illustrates most simply how everyone can benefit from trade, the gains would be similar if the rancher and the farmer were each capable of producing the other good, but only at great cost. Suppose, for example, that the potato farmer is able to raise cattle and produce meat, but that he is not very good at it. Similarly, suppose that the cattle rancher is able to grow potatoes, but that her land is not very well suited for it. In this case, it is easy to see that the farmer and the rancher can each benefit by specializing in what he or she does best and then trading with the other.

The gains from trade are less obvious, however, when one person is better at producing every good. For example, suppose that the rancher is better at raising cattle and better at growing potatoes than the farmer. In this case, should the rancher or farmer choose to remain self-sufficient? Or is there still reason for them to trade with each other? To answer this question, we need to look more closely at the factors that affect such a decision.

Suppose that the farmer and the rancher each work 40 hours a week and can devote this time to growing potatoes, raising cattle, or a combination of the two. Table 3-1 shows the amount of time each person requires to produce 1 pound of each good. The farmer can produce a pound of potatoes in 10 hours and a pound of meat in 20 hours. The rancher, who is more productive in both activities, can produce a pound of potatoes in 8 hours and a pound of meat in 1 hour.

Panel (a) of Figure 3-1 illustrates the amounts of meat and potatoes that the farmer can produce. If the farmer devotes all 40 hours of his time to potatoes, he produces 4 pounds of potatoes and no meat. If he devotes all his time to meat, he produces 2 pounds of meat and no potatoes. If the farmer divides his time equally between the two activities, spending 20 hours on each, he produces 2 pounds of potatoes and 1 pound of meat. The figure shows these three possible outcomes and all others in between.

This graph is the farmer’s production possibilities frontier. As we discussed in Chapter 2, a production possibilities frontier shows the various mixes of output that an economy can produce. It illustrates one of the Ten Principles of Economics in Chapter 1: People face tradeoffs. Here the farmer faces a tradeoff between producing meat and producing potatoes. You may recall that the production possibilities frontier in Chapter 2 was drawn bowed out; in this case, the tradeoff between the two goods depends on the amounts being produced. Here, however, the farmer’s technology for producing meat and potatoes (as summarized in Table 3-1) allows him to switch between one good and the other at a constant rate. In this case, the production possibilities frontier is a straight line.

Panel (b) of Figure 3-1 shows the production possibilities frontier for the rancher. If the rancher devotes all 40 hours of her time to potatoes, she produces 5 pounds of potatoes and no meat. If she devotes all her time to meat, she produces 40 pounds of meat and no potatoes. If the rancher divides her time equally, spending 20 hours on each activity, she produces $21 / 2$ pounds of potatoes and 20 pounds of meat. Once again, the production possibilities frontier shows all the possible outcomes.
