Below are two papers from Perce Harpham, an advocate of a Universal Basic Income (UBI).
Inequality: A New Zealand Crisis contains a brief proposal for a UBI along slightly different lines, as set out by Gareth Morgan and Susan Guthrie.
Here, Harpham’s introduction paper brings, in his words, a partial solution to the inequality issue. It offers a means of financing a Universal Basic Income and shows that the tax regime and UBI should be considered together – not separately, as has always been done by various Commissions of Enquiry over the years.
The values chosen for tax rates and UBIs can be varied to give different results for how much one wishes to reduce inequality. The spreadsheet lets people vary these themselves and see what the effect is on individuals of different ages and levels of wealth.
