Women’s employment rates and wages are still lagging those of men across OECD countries, with average employment and wage gaps now around 15% and 12% respectively. Gaps narrowed at a relatively modest pace over the past decade, calling for further policy action. A lack of affordable high-quality childcare is often an obstacle to women’s participation in the labour market and notably to working full time. A very unequal sharing of parental leave between parents and challenges upon return to work further hampers women’s careers. Biases in the tax system may discourage women from working in some countries. Women face disadvantage in accessing management positions and entrepreneurship. A range of policies can help reduce gender gaps, including better childcare provision, incentivising parents to better share parental leave, re-skilling and upskilling on return from parental leave, encouraging gender equality within firms, integration programmes for foreign-born women, promoting women entrepreneurship and financial inclusion, and levelling taxation for second earners. Moreover, the multiple dimensions and root causes of gender inequality call for mainstreaming gender across policy domains.
