Finally, complexity and imperfectly rational behavior can combine to create new opportunities for tax policy to achieve social goals.

For example, the result that the EITC strongly encourages work may be due in part to the fact that the EITC follows a complicated schedule, to which recipients can bring only limited attention and limited computational resources.
