There have been a vast number of social security reforms aimed at increasing employment at older ages over the last two decades in the Netherlands. These reforms mainly lead to more stringent eligibility criteria for, and reduced generosity of, social security programs. Our empirical evidence suggests that these reforms are likely to have contributed to individuals working longer, but it is difficult to pinpoint which reforms have been most effective. Furthermore, we show that the recent increase in the state pension eligibility age is likely to further increase employment at older ages.
