“…Child-care subsidies are also associated with increased enrollment in center care (Weinraub et al 2005;Burstein and Layzer 2007;Ryan et al 2011;Ertas and Shields 2012), and, although findings are mixed, some studies link subsidies to the use of higher-quality arrangements (Johnson, Ryan, and Brooks-Gunn 2012;Krafft, Davis, and Tout 2017). Yet, studies also find that subsidy spells are generally brief and participants cycle off and on the program, often returning with a new provider (Meyers et al 2002;Ha and Meyer 2010;Ha, Magnuson, and Ybarra 2012;Weber, Grobe, and Davis 2014;Pilarz, Claessens, and Gelatt 2016).While some exits are precipitated by income gains suggestive of upward economic mobility, many families remain income eligible after leaving the program. Short spells and dynamic program use raise concerns about the effectiveness of the child-care subsidy program to support stable employment and children's healthy development and contribute to long-term economic stability for families with unstable use.…”
