“…Findings from Dolton and von der Klaauw (1995), Feng (2009), Glazerman et al (2012), and Hanushek, Kain, and Rivkin (2004) imply inelastic labor supply, while studies by Clotfelter et al (2008), Falch (2010), and Feng and Sass (2016) find somewhat larger labor-supply elasticities. However, in contrast to the mixed findings from research on the teaching workforce as a whole, studies of senior teachers consistently show a high degree of responsiveness to pension system incentives (Furgeson et al, 2006;Costrell and McGee, 2010;Brown, 2013;Fitzpatrick and Lovenheim, 2014;Ni and Podgursky, 2016;Knapp et al, 2016). Traditional teacher pension plans (i.e., final average salary defined-benefit) contain strong incentives designed to "pull" teachers to certain combinations of age or experience, and then "push" them into retirement.…”
