Using a simulated instrument strategy, we analyze how expansions to the federal and state Earned Income Tax Credits (EITC) affected household finances over the past two decades. Using data from the Survey of Income and Program Participation wealth topical modules, we also test whether responses differ over time, as well as whether there are different responses to the federal and state expansions, and how responses vary by educational attainment. A $1,000 policy‐induced increase in the average household EITC leads to a 3 percentage point increase in the likelihood of holding money in a savings or checking account, and approximately $700 more held in savings balances. These results are coupled with large increases in pre‐tax family earnings. We also find some evidence of decreases in unsecured debt holdings. We interpret these results as further evidence that the EITC increases the financial stability of low‐income single mothers. 相似文献

There is growing interest in the use of unconditional cash transfers as a means to alleviate poverty, yet little is known about the effects of such transfers in the U.S. This paper reports on the results of a randomized controlled study of a one-time $1,000 unconditional cash transfer in May 2020 to families with low incomes in 12 U.S. states. The families were receiving, or had recently received, Supplemental Nutrition Assistance Program benefits. We examine the impact of the cash transfer on five pre-registered outcomes (material hardship, mental health, parenting, child behavior, partner relationships) and several secondary outcomes (hardship avoidance, consumption, employment, benefit use). We find no statistically significant effects (powered to detect effects of 0.09 standard deviations) of the cash transfer on any outcomes for the full sample. In pre-specified exploratory analyses, we find significant reductions in material hardship (-0.17 standard deviations) among families with less than $500 of earnings in the previous month, roughly the bottom 50 percent of monthly earnings for the study sample. 相似文献

The protests of December 2001 in Argentina were the most visible manifestation of a larger cycle of contention, which continues to have a substantial influence on the forms, tactics and goals of social movements throughout the country. This paper provides a critical overview of these lasting effects. In particular, we focus on three areas where the consequences of the crisis for collective action have been particularly strong: performative politics, coalition-building, and institutional support for grassroots networks. We conclude by reflecting on the implications for participatory democracy and the consolidation of a highly engaged civil society. 相似文献
