because it's just a toy model, but nevertheless,

这只不过是一个极其简单的模型
let's try and draw out some lessons from this model.

下面我们从中总结点经验教训吧
So here what we did was we changed the payoff to cheating,

我们改变了偷逃税款的收益
we made it worse.

但我们却把事情给搞砸了
But a different kind of change is we could have changed, sorry,

其实我们还可以改变别的东西
we changed the payoff negatively to being caught cheating.

我们降低了被抓到偷逃税款的收益
But a different change we could have done

但实际上我们还可以
is we could have left the -10 in place

放着-10在那不去管它
and we could have raised the payoff to cheating and not getting caught.

我们可以提高成功逃税的收益
We could have left this 10 in place

我们大可不去理会这里的10
and changed this 4 let's say to a 6 or an 8.

却把这个4改成6或者8
We've increased the benefits to cheating if you're not caught.

我们提高了成功偷逃税款的收益
