I think there are a lot of complexities there in terms of how to determine the reason that the income went down. Is it because of reduced effort? Is it because of creative accounting? Is it because of an exogenous factor, such as an economic downturn?
I think that's what the international experience shows, that it's very difficult to design a system like this. I think that's why you will have a very hard time finding a country that provides employment insurance in situations of business downturn.
