Most economists do not share the hypothetical concern that a UBI would cause high inflation
"...most economists do not share the hypothetical concern that a UBI would cause high and general inflation, because there is no reason to assume that a UBI could not be financed by taxes and dividends—which would use money already in circulation, rather than newly printed money. Insofar as inflation does not involve an expansion in money supply, then, a UBI should not lead to high or hyperinflation."
