“…Studying the location decision is important because the location pattern is a critical determinant of formal and informal care arrangements (see Checkovich and Stern (2002), Engers and Stern (2002), Bonsang (2009), andHiedemann, Sovinsky, andStern (2013)). There are myriad economics and noneconomics studies on co-residence and collocation between elderly parents and their children (e.g., Börsch-Supan, Kotlikoff, and Morris (1988), Dostie and Léger (2005), Hank (2007), Fontaine, Gramain, and Wittwer (2009), Johar and Maruyama (2011), Compton and Pollak (2013), Johar and Maruyama (2014), Maruyama (2015), and Wiemers, Slanchev, McGarry, and Hotz (2017)), but few investigate the noncooperative decision of family living arrangements, 1 and none quantifies the free-rider problem among siblings, although the discrete and long-term nature of location decisions may reinforce the free-riding and strategic behavior involved in the coordination of caregiving among siblings.…”
