“…First, several studies have examined the relationship between informal and formal care provision (Pezzin et al, 1996; Van Houtven and Norton, 2004 and 2008; Hanaoka and Norton, 2008; Bonsang, 2009; Spillman and Long, 2009; Tamiya et al, 2011; Kikuchi, 2012; Paraponaris et al, 2012) and found that informal care substitutes for formal care although the effects differ by situation. Second, previous literature has established that providing informal care negatively affects the caregiver's labor supply (Carmichael and Charles, 1998 and 2003; Pezzin and Schone, 1999; Noguchi and Shimizutani, 2004; Carmichael et al, 2010; Hassink and Van den Berg, 2011; Tamiya et al, 2011; Otsu and Komamura, 2012; Van Houtven et al, 2013) and health (Kishida and Takagi, 2007, and Suzuki et al, 2008). Third, previous research has explored who becomes a caregiver within a family (Fontaine et al, 2009; Pezzin et al, 2009), finding that economic conditions of siblings and the relationship between children and parents significantly affect this decision.…”
