A universal basic income could cause inflation by reducing the labor units required to earn the dollar.

“As we explained in the subsection on price stability, the value of the dollar is determined on the margin by what must be done to obtain it. If money ‘grew on trees,’ its value would be determined by the amount of labor required to harvest money from trees. In an ELR program, the value of the dollar is determined on the margin by the number of minutes required to earn a dollar working in the ELR job—six minutes in our example above. Assuming that BIG provides an equivalent payment of $20,000 per year to all citizens ($10 per hour for a normal 2000 hour working year), the value of the dollar on the margin would be the amount of labor involved in retrieving and opening the envelope containing the annual check from the treasury, divided by 20,000. Obviously, the purchasing power of the dollar in terms of labor units would be infinitesimally small under a universal BIG scheme. Again, as we said above, this is the logical conclusion of the inflationary process that would be set-off by implementation of such a BIG program—it might not happen overnight.”
