This paper uses a microsimulation model to ask whether welfare recipients i
n the United States would work full-time if offered an earnings supplement
that was conditioned on full-time employment. The simulations suggest that
the earnings supplement would increase full-time employment, with little ad
ditional cash transfer cost to the government. In contrast, financial incen
tives currently being used by many of the states are increasing employment
and income, but are encouraging primarily part-time employment. Encouraging
full-time employment is particularly important in light of new time limits
on welfare receipt. Faced with a loss of welfare benefits, many recipients
may find that part-time earnings do not allow them to be economically self
-sufficient. (C) 2001 by the Association of Public Policy Analysis and Mana
