Substitution and income effects work in opposite directions. Phase-out: Similar to negative income tax. Both substitution and income effects work in the same direction and reduce the incentive to work. Compared to the welfare program, EITC results in more work incentive Chapter 3-21 EITC: • • Phase-in: It provides a refundable tax credit equal to 20% of earned income-up to $500 for individuals and $1,000 for families. To target assistance to those with lower incomes. Phase-out: The credit is reduced by 15% of net income for individuals earning more than $9,500 and families earning more than $14,500.
