This document summarizes a discussion on raising pension contribution rates in the UK. It discusses how longevity has increased the ratio of time spent in retirement to time spent working. To achieve adequate retirement incomes, both high participation rates in pensions as well as adequate contribution rates are needed. Currently, reforms have focused on participation rates, but contribution rates of 8% of earnings may not be enough. Raising contribution rates could involve increasing regulations on minimum contributions, improving education, using incentives, or nudges like automatically increasing contribution rates over time. Both employee and employer contribution rates may need to increase, but this requires balancing adequacy with preventing increased opt-outs.
