Introduction to the 20^th Anniversary Special Issue of the Journal of Pension Economics and Finance

The papers in this 20th Anniversary Special Issue reflect to a large extent how the fields of pension economics and pension finance have developed in the past two decades, although there remain very clear connections to the research published in the Journal's first issue. While there has been great progress in research on pensions and retirement economics over the last 20 years, there remain important outstanding questions for future study.
