Earned Income Tax Credit 

There is strong evidence that the Earned Income Tax Credit (EITC) increases employment and income for participating families (Strully 2010,UW IRP-Dahl 2009, Hotz 2003, Ellwood 2000, NBER-Meyer 2000, Meyer 2001, Eissa 1996).
The EITC increases employment for single-parent households (Simpson 2010), especially those headed by mothers (Strully 2010, UW IRP-Dahl 2009, Ellwood 2000, NBER-Meyer 2000, Meyer 2001, Eissa 1996)
Increasing family income through employment and earnings supplements has been shown to have positive effects on children, most consistently on school achievement among elementary school students (NCCP-Cauthen 2002). Receipt of the EITC is also associated with improved maternal (NBER-Evans 2010) and child health, including reduced infant mortality (Arno 2009) and incidence of low birthweight births (NBER-Hoynes 2012, Strully 2010).
