loaning some money to one of your classmates for some project.

比如说借给你同学来运行某项目
Let's try here.

你来回答吧
Something like loan money over time in stages and observe progress.

可以根据使用情况分阶段发放贷款
Good, so one possibility is to break the loan up and give it,

好的可以把整笔贷款分阶段发放
let it come in small installments.

每一阶段都只发放一小部分
If you do well on the first installment

如果你第一阶段进展得不错
I'll give you a bigger installment next time.

那我下次就发放更大一笔的款项
Notice that that's a little bit like something

其实这个和第一讲的时候
we talked about in the very first week.

我们所探讨的有点类似
It's a little bit like taking this one shot game

就是把一个单回合的博弈
and turning it into a repeated game.

变成一个重复博弈
It's turning a one shot interaction into a repeated interaction.

把单回合博弈变成重复博弈
