A couple things I am curious about:<p>- Basic income is usually proposed as a replacement to some or all services and income support people currently receive. I wonder if it is feasible to simulate that -- e.g. adjust it downwards for people receiving more public assistance (other than things like medicaid of course), or paying lower taxes, etc. -- this of course would depend on the funding model(s) to which results need to be applicable. Otherwise, following the study, people will surely say that what was tested is very different from what was proposed.<p>- Systemic effects would be relatively hard to evaluate with such a study, an example would be the change in both absolute and relative prices: e.g. I would expect that after a wide adoption, housing prices in cheap and mid-level areas might rise more than in currently expensive areas, because the added income would change the purchasing power of lower-income households by a much larger percentage -- or perhaps not. I guess it might be possible to try to account for things like this at the data analysis stage.
