Using a simulation model for a small open economy (Quebec 1986), vario
us Negative Income Tax (NIT) and workfare schemes are compared from th
e point of view of efficiency and equity. The main finding is that the
re exist workfare schemes that are superior both to the Quebec regime
of 1986, and to a NIT characterized by a 100 percent implicit tax rate
. However, these workfare schemes are dominated by some NIT programs.
This suggests that it may be necessary to have work requirements that
vary across socio-demographic classes for a workfare plan to be superi
or to any NIT. Combining workfare with an NIT could also be the prescr
iption.
