Concerns about undersaving for retirement have led to policymakers implementing reforms aimed at boosting saving. One such policy is 'automatic enrolment' – where rather than having to choose to contribute to a pension, employees have actively to choose not to save in one. Since October 2012, the UK has been in the process of implementing the first-ever national roll-out of such a policy. This paper exploits the gradual roll-out of this obligation for employers to enrol their employees into a pension to estimate its effect on how much is saved in workplace pensions for private sector employees.
