From the abstract:
Many studies examine the anti-poverty effects of social insurance and means-tested transfers, relying solely on survey data with substantial errors. We improve on past work by linking administrative data from Social Security and five large means-tested transfers (SSI, SNAP, Public Assistance, the EITC, and housing assistance) to 2008-2013 Survey of Income and Program Participation data. Using the linked data, we find that Social Security cuts the poverty rate by a third – more than twice the combined effect of the five means-tested transfers. Among means-tested transfers, the EITC and SNAP are most effective. All programs except for the EITC sharply reduce deep poverty (below 50% of the poverty line), while the impact of the EITC is more pronounced at 150% of the poverty line. For the elderly, Social Security single-handedly slashes poverty by 75%, more than 20 times the combined effect of the means-tested transfers. While single parent families benefit more from the EITC, SNAP, and housing assistance, they are still relatively underserved by the safety net, with the six programs together reducing their poverty rate by only 38%. SSI, Public Assistance, and housing assistance have the highest share of benefits going to the pre-transfer poor, while the EITC has the lowest. Finally, the survey data alone provide fairly accurate estimates for the overall population at the poverty line, although they understate the effects of Social Security, SNAP, and Public Assistance. However, there are more striking differences at other income cutoffs and for specific family types. For example, the survey data yield 1) effects of SNAP and Public Assistance on near poverty that are two-thirds and one-half what the administrative data generate and 2) poverty reduction effects of SSI, Social Security, and Public Assistance that are 34-44% of what the administrative data produce for single parent families.

New evidence shows that our anti-poverty programs, especially Social Security, work well

Few U.S. government efforts are consistently more vilified than anti-poverty programs. They’re dismissed as ineffective and ridiculed as giveaways to undeserving recipients. A new paper puts the lie to these assertions by showing that the nation’s most important anti-poverty efforts all succeed in serving their goals — in the case of Social Security, spectacularly. The authors, Bruce D. Meyer and Derek Wu of the University of Chicago, used administrative statistics from six major programs to demonstrate that five of the six “sharply reduce deep poverty” (that is, income below 50% of the federal poverty line) and the sixth has a “pronounced” impact among the working poor…..
