That's a great point, Arvind. Thanks. So do you think that conditions increase the likelihood of corruption in the scheme, relatively to just cash? One of the problems with tightly controlled evaluations is of course that they virtually eliminate those kind of problems that are bound to occur in the scale-up, so these implementation issues are seldom looked at. It would be great if you can point us to work on that, since many readers may be interested. Even sharing experiences on how this happens would be super helpful as countries try to design similar schemes.
