“…Children may also serve as informal substitutes for formal long‐term care, such as when an adult child cares for her ailing parents. There are a large number of papers that examine, both theoretically and empirically, a wide range of trade‐offs between work, leisure, the supply of informal care, the demand for formal care, and end‐of‐life transfers (e.g., Chang and White‐Means, 1995; Stern, 1995; Nocera and Zweifel, 1996; Sloan, Hoerger, and Picone, 1996; Sloan, Picone, and Hoerger, 1997; Pezzin and Schone, 1999; Lo Sasso and Johnson 2002; Brown, 2006). A very careful summary of the literature through the late 1990s can be found in Norton (2000) and is therefore not recreated here.…”
