could have. just after the award was announced, you said it was a not so much like hard science, molechineering plumbing, breaking the big problem into manageable chunks and solving them through accommodation of intuition, trial and error, and so on. i suppose it is an interesting analogy, but the argument may be made that the plumber can certainly remove the blockage, but the plumber can't ensure you are getting your fair share of the water, of the basic resource. isn't that the danger of the approach, that you are kind of seeing the minute but actually you are not solving the fundamental problems that lie behind it? this could be reversed, which is that you could be reversed, which is that you could have the very best engineering solution in place, and the most modern water technique, water system, in your city, but if the plumbing is not there, nobody is going to get the water. so i don't think we are claiming that all economists need to do is running randomised controlled trials and worrying about the plumbing. all we are claiming is that some economists need to do some plumbing som
