I am starting an analysis of how service delivery (if someone got a service nor not) impacted their income. There is essentially zero literature on this in my field (vocational rehabilitation).
One of the many issues I was thinking about is that counselors say, customers need a service. But to see if the service matters I need to assess who got the service (which I have) versus who did not get it and needed it.
Yes. The metric ignores baseline which is why I was going to measure just that. The federal government does not care about if you gain or lose income just what your income is at the end - although income gain always made more sense to me and why I analyzed that way in the past.
