system, but let's just see if we can figure this out.

但现在我需要你们搞懂这些公式
So equilibrium is this very involved thing.

均衡是很复杂的
What everybody does depends on what everybody else is going to

人们的行为依赖于身边其他人的行为
do because how much should you pay for something depends on how

因为你的买价取决于
much you think you can get it by offering it to some other guy.

你买东西时付给给他人的价格
If there are a million A's and a million B's,

如果市场上有无数AB代理商
you're dealing with one of the B's, maybe the other B will give

你和其中的一个B代理商做生意时
you a better deal.

可能还会有其他B给你提供更好的生意
So you have to think about what the other people are doing

所以你在做最后的决定前
before you can decide what to do yourself.

你需要考虑一下其他人在做什么
All that is captured by the idea of the prices.

这些都依赖于价格
Somehow people get into their minds what the best deal they can get is.

依赖于人们想获得更好的买卖
