“…Past research on age dissimilarity mostly expected dysfunctional age dissimilarity effects on employee outcomes such as job performance, extra-role performance, inclusion, and relationship conflict (e.g., Caldwell et al, 2008;Chattopadhyay, 1999;Jehn et al, 1997;Kurtulus, 2011;Liao et al, 2004;Pelled et al, 1999;Van der Heijden et al, 2010). However, it often did not confirm its predictions and reported nonsignificant, dysfunctional, or even beneficial effects (Guillaume et al, 2012(Guillaume et al, , 2014Schaffer, 2019;Schaffer & Riordan, 2013). Therefore, empirical research is needed to test the mechanisms and moderators of age dissimilarity effects (Guillaume et al, 2012(Guillaume et al, , 2014.…”
