Influence of the basic income guarantee

Predicted positive effectsPredicted negative effects
It might increase work incentives (Effect 1#)Might increase work disincentives (Effect 2)
As a cash transfer much more efficient than in-kindIn case of keeping budget-neutrality a very small size of a payment
Will increase stability on labour marketA bigger payment requires tax increase → a work disincentive
Lower administrative costs than in current programmesHigher taxes → a bigger deadweight loss
Less exclusive and humiliating for recipientsAfter BIG implementation the needy might loose
