This is interesting. By making things more transparent, you have obvious and measurable positive effects. Here's my question. What happens when someone moves up a social class such that they're no longer in poverty? I suppose then that they're no longer eligible for the program. How do you administrate the program so that those people are no longer given rice?

I suppose then that the lists held by the distribution centers need to be regularly updated. But then when someone is on the margin (or perhaps for everyone above the poverty line), they can have incentive to say, "Look, here's my card, I'm eligible!" Then the distribution center says, "Nope, says here that you're not poor anymore." Those disputes would need to get resolved, and I can imagine that they can get bogged down in bureaucracy. Worse still, for cases on the margin, distribution centers may have ability to let corruption decide that recipients should be ineligible when they're eligible.

I think that the idea and results are great. I'm just curious how they deal with the cases on the margin. Or does resolution just wait until the next year's income taxes get filed and everyone gets reprocessed accordingly to check for status changes?
