这段录音讲述了经济学和贸易

笔果还原听力原文:
Comparative advantage is the theory of trade. It explains why people trade and which goods people should trade if they want to maximize their well-being. It is actually useful to understand comparative advantage to begin with a false theory. A very plausible, but incorrect theory of trade, namely the theory of absolute advantage. So let’s consider a simple model. Let’s suppose that labor is the only goods that used in production, and we can produce computers or shirts. Now let’s suppose that in Mexico, it takes 12 units of labor to produce 1 computer, and again in Mexico, it takes 2 units of labor to produce 1 shirt. Now let’s compare it with the United States, to make it simple, we’ll suppose that in United States, it only takes 1 units of labor to make 1 computer, and 1 unit of labor to create 1 shirt. Now, from the absolute advantage theory of trade, it should, it may seem obvious that there should be no trade here, it may seem obvious that the united states will outcompete Mexico on all margins. After all, the United States in this example, is much more productive at producing computers, and also more productive at producing shirts than Mexico. So this is the case that we might think that the United States is so much better at producing both computers and shirts, that certainly there is no reason for the United States to trade with Mexico, its less productive neighbor.
