Many EU Member States have implemented reforms to improve the sustainability of their pension systems. However, the impact of discouraging early retirement and increasing the pension age on effective retirement ages is limited, as many people are unable or unmotivated to work until pension age. Reduction of working time is one approach to enabling people to work longer than would have been feasible if they continued working full time. But a barrier to reduction of hours is the loss of income. Partial retirement schemes address this barrier by substituting part of the income loss with a partial pension or benefits. This report investigates how partial retirement schemes can contribute to sustainable and adequate pension systems by enabling and motivating people to extend their working lives. It maps schemes at the national and sector levels in the EU and Norway, examines their characteristics and assesses their impact on the extension of working lives. An executive summary is available - see Related content.
