Book excerpt: The 2020 edition of the OECD Pensions Outlook examines a series of policy options to help governments improve the sustainability and resilience of pension systems. It considers how to ensure that policy makers balance the trade-off between the short-term and long-term consequences of policy responses to COVID-19; how to determine and assess the adequacy of retirement income; how funded pension arrangements can support individuals in non-standard forms of work to save for retirement; how to select default investment strategies; how to address the potential negative consequences from frequent switching of investment strategies; and, how retirement income arrangements can share both the investment and longevity risks among different stakeholders in a sustainable manner. This edition also discusses how governments can communicate in a way that helps people choose their optimal investment strategies.
