“…A key aim of these reforms is to encourage older workers to remain in the labor force, making it vital to understand how these policies affect retirement decisions. While several studies find large effects of these reforms on retirement decisions (e. g., Börsch-Supan and Schnabel, 1998;Snyder and Evans, 2006;Hanel and Riphahn, 2012;Staubli and Zweimüller, 2013;Vestad, 2013;Cribb, Emmerson and Tetlow, 2016;Lalive, Magesan and Staubli, 2017;Geyer and Welteke, 2019), it has been difficult to disentangle the key mechanisms as these reforms may affect retirement behavior through several channels. For example, these reforms may encourage people to delay retirement due to (i) a decrease in individuals' lifetime pension wealth, known as the wealth effect, (ii) the opportunity to work for a longer period and thus accrue a larger pension, known as the accrual effect, (iii) a change in social norms, (iv) the presence of liquidity constraints, or (v) a deferral of any income/earnings test, which discourages work among individuals who are eligible for a pension.…”
