The Personal Responsibility and Work Opportunity Reconciliation Act of 1996 imposed limits on the amount of time that a family could receive cash welfare payments during its members’ childhoods. Groggier and Michalopoulos (2003) found that these time limits led to immediate reductions in the number of people receiving welfare benefits, even though nobody in the family had reached his or her time limit. Which group of families should be particularly sensitive to the introduction of these time limits: those with younger children or those with older children? Explain your answer.
