Negative income is based on the idea that there is something taxable on the other end to strive for. That it's there for those who don't have jobs but the second they get it they will be taxed. Negative income requires a system of control and so it's basically not very different than a normal conditional social wellfare system. UBI is basically working on the premise that there wont be any jobs in the ned. That there wont' be any income to tax. So it's not really equivalent to UBI as it's premise is that there will the number of available jobs just fluctuate but we will get more over time.
