I hoped I would find some more interesting information in this piece of blog. I suppose that no one was infering that RCT would reduce poverty, only that they can help measure the effect on poverty of a given intervention. Yes, the intervention should be relevant and responding to a real need. Who said (and why) that RCT don't say anything about what happens if a government is implementing a program? Why can't RCT be administered on a gvt-implemented program? I know of bank-financed (and gvt-implemented) projects that use randomized design. It's kind of frustrating to be told that you cannot measure impact if you don't have control groups and then that RCT are kinda worthless anyway.
