Sources: Weighted Survey of Income and Program Participation, state policy, and economic data for 1992, 1995, 1998, 2003, 2005, 2010, and 2011.

Notes: Robust standard errors clustered by state in brackets. Models also included controls for demographic characteristics of the household, state economic considition state and year fixed effects (see Section 4 for the complete list of controls). Instrumental variables in two-stage least squares models and IV poisson model are simulated share of children eligible for public health insurance and SNAP outreach spending per person with income below 150 percent of the federal poverty line.
