I strongly agree with Derek’s point about measuring the nonmonetary costs to the recipients and their families. If your benefits are driven mainly by the differences in costs, then omitting potentially relevant costs can invalidate the entire analysis. You absolutely must account for the time that recipients spent in the program, and traveling to and from the program, and any other money or time costs that they or their families incurred as a result of program participation. At minimum, this time should be valued at the local wage rate. Until this is addressed, I will assume that your analysis is junk, and say so to anyone who asks me about it.
