Abstract
Research has shown that giving disadvantaged families financial incentives to invest in their children could decrease socioeconomic inequality by enhancing human capital formation. Yet, within the household how are such gains achieved? We use a field experiment to investigate how parents allocate time when they receive financial incentives. We measure parental investment using the time parents report spending with each child in the family. We aim to determine whether financial incentives increase investment in target children, potentially at the expense of time spent with non-targeted children.

Interventions
Intervention(s)
Our study involves the Parent Academy treatment arm of the Chicago Heights Early Childhood Center (CHECC). Families in Chicago Heights will be randomly assigned to Parent Academy, which will hold classes to help parents teach to their preschool-aged child. Parents will be assigned homework to complete with their preschool-aged child, complete evaluations with their preschool-aged child in the presence of trained staff, and take their child to assessments held at CHECC. Some parents will receive financial incentives paid to them immediately in cash, while other parents will receive financial incentives deposited to a savings account that they can only access when their target child is ready to enroll in post-secondary education.

Primary Outcomes
Primary Outcomes (end points)
We will focus on the amount of time parents spend investing in the target child compared to non-targeted siblings. This time is primarily time spent teaching.
We will also use performance in Parent Academy as a measure of parental investment. Parents are required to complete homework with the target child, which is a form of time investment. We will take variation in target child's performance on evaluations and assessments (controlling for baseline academic performance) as another measure of parental investment.

Experimental Design
Experimental Design
In both conditions, parents will have access to Parent Academy. Parent Academy provides parenting classes, homework assignments for the parent and target child, evaluations for both the parent and target child, and assessments for the target child. The parenting classes and homework are designed to improve the skills of target children, provided the parent invests time in these activities. The evaluations and assessments are designed to measure target child skills. For all four activities, parents receive financial incentives.
For attending parenting classes, parents will receive earnings in cash. For homework assignments, evaluations, and assessments, only parents in the immediate condition will receive earnings in cash. Parents in the delayed condition will have their earnings deposited into a bank account that is only accessible when the target child enrolls in post-secondary school.
