It is thus in the public interest to facilitate savings for children’s future. Child Development Account (CDA) policies provide a structured, incentivized way for children to accumulate assets. Such policies have recently been adopted in the United Kingdom, Canada, South Korea, and Singapore (Loke & Sherraden, 2009). In the United States, there is also growing interest in CDAs. At the federal level, several CDA bills have been introduced, including the America Saving for Personal Investment, Retirement, and Education (ASPIRE) Act, Young Savers Accounts, 401 Kids Accounts, and Baby Bonds (Cramer, 2008; Loke & Sherraden, 2009). Despite growing interest in CDAs, there is little empirical knowledge to guide policy design. Specifically, we know little about (1) whether CDAs facilitate savings for children, especially those from low- and moderate-income families, and (2) whether incentives help build such savings. This study examines savings outcomes in the first large-scale demonstration of CDAs in the United States—the Saving for Education, Entrepreneurship, and Downpayment (SEED) initiative. It is also the first empirical study, to our knowledge, to investigate associations between savings outcomes and incentives in an asset-building program for children. This study enhances knowledge about saving in CDAs, incentives in public policy in general, and incentives in savings policy in particular. Results can inform CDA policy design.
