Welfare Programs and Labor Supply

The labor supply and other work incentive effects of welfare programs have long been a central concern in economic research. Work has also been an increasing focus of policy reforms in the U.S., culminating with a number of major policy changes in the 1990s whose intent was to increase employment and earnings levels of welfare recipients and other disadvantaged individuals. This paper reviews the economic research on this topic, covering both the theoretical models that have been developed as well as the empirical findings from econometric studies of the effects of existing welfare programs on labor supply.
