“…The findings of Lennartsson, Silverstein, and Fritzell (2010) similarly indicate that parents provide economic transfers if they have more frequent social contact with any of their children, and that these time investments pay off for children of higher social class origins. This is linked to social exchange theory and equity theory, which posit that flows between adult children and parents are based on the premise that social relationships are governed by a norm of reciprocity, that both search for balanced transactions and repayment of past transfers through their life courses and that balanced relationships enable higher well-being (Silverstein, Conroy, Wang, Giarrusso, & Bengtson, 2002;Grundy, 2005;Lowenstein, Katz, & Gur--Yaish, 2007). Transfer motives can range from pure altruism to paternalistic behaviour to self-interested strategic exchange, and these motives overlap and interact (Kohli & Kunemund, 2003).…”
