> No, they prove that people who are in a program that is very clearly temporary will not end their careers for a short pilot program. This means nothing.
They provide lower bounds on the amount of time you can offer a guaranteed income without adverse effects on people's employment. Going to an extreme, if you offer people a 40 year UBI and they don't quit, then that's pretty damn strong evidence. 3 years offers some evidence; for particular subpopulations with short time horizons, if they keep on working for three years on UBI, I'd bet almost arbitrary amounts of money they'll keep on working indefinitely.
> No. If you make $1k from a job and $1k from a pilot program each month, you spend the $1k from the pilot on legitimate bills and now you have $1k to spend however you like. The study can't trace that money. (This isn't to say everyone on UBI uses it for drugs, rather, it's to point out that you cannot deduce they don't just by tracing the way the transfer payments are spent)
I believe these studies rely on self-reported alcohol etc consumption. The issues with self-reported consumption are already well-known and well-characterized.
> No kidding. You gave someone several thousand dollars no strings attached in a situation where neither taxes nor inflation would rise as a result.
These things are always worth verifying. One of the criticisms against a UBI is that it'll create a population of depressed losers who never interact with society. If people's lives and happiness are improved, that addresses that criticism.
> What UBI skeptical people want to know is where is the proof that we can afford to tax ourselves to pay ourselves, where is the proof that it won't hurt long term productivity, and where is the proof that it doesn't cause inflation. A 120 person 36 month trial program cannot answer any of these questions.
Could anything short of a full UBI implementation work as proof for you? If not, can you suggest what would? If, say, you took a random selection of 1000 people and promised them a lifelong UBI, and their labor force participation and levels of happiness stayed the same over the first ten years of the program, would that serve as proof to you?
