“…Firm-level outcomes of age-related HRM typically include performance-related constructs such as firm performance (e.g., Bieling et al, 2015;Kunze et al, 2013), employee productivity (e.g., Göbel & Zwick, 2013), return on assets (e.g., Ali & French, 2019), turnover (intention) (e.g., Boehm et al, 2014;Stirpe et al, 2018) and firm-level sickness absence (e.g., Ybema et al, 2020). In addition, various studies investigated knowledge-oriented constructs such as workers' expertise (Calzavara et al, 2019) or dyadic and team knowledge sharing (e.g., Burmeister et al, 2018;Sammarra et al, 2017) as well as aspects of an age-friendly workplace (e.g., Eppler Hattab et al, 2020).…”
