IFS identifies three potential drivers causing gender pensions gap By Jean-Baptiste Andrieux 11 th May 2021 2:55 pm The Institute for Fiscal Studies has identified three drivers that could be responsible for the gender pensions gap. These are the variance in labour market experiences, contrast in saving rates and range of investment strategies according to a note on its website. The think tank said it is important to understand these drivers before determining what policy intervention is necessary. It added the drivers have changed over time with the increasing prevalence of career average earning schemes and the introduction of auto-enrolment. This means the gaps in pension income today might reflect previous labour markets and pension arrangements.
