This paper reviews the economic literature on welfare reform over the 1990s. A brief summary of the policy changes is followed by a discussion of the methodological techniques that analyze the effects of these changes on outcomes. The paper then critically reviews the econometric and experimental literature on caseload changes, labor force changes, poverty and income changes, and family formation changes. A growing body of evidence suggests that recent policy changes have influenced economic behavior and well-being. One particular set of "new-style" welfare programs seems to show especially promising results, with significantly increased work and earnings and reduced poverty.
