This manuscript broadly describes the potential application of behavioral insights--particularly behavioral economics--to early childhood interventions (broadly construed as parent-targeted initiatives designed to support and improve early childhood learning and development). We start by giving an overview of the current work being done in early childhood interventions. This is followed by an overview of behavioral economics and the ways in which it sheds light on early human development, especially in the context of poverty, and the intersection of underlying conceptual constructs between behavioral economics and developmental theory. We then describe the application of behavioral economic insights to programs more generally and provide a few examples with illustrative parent coaching, early childhood literacy, and home visiting program models.
