The pandemic of Covid-19 exposed critical gaps in social policy and underscored the foundational role of families and households in both societal and economic stability. This introductory chapter to a Special Issue explores the interdependence between formal economic participation and unpaid domestic labour – collectively referred to as ‘social reproduction’. Drawing on feminist political economy, the chapter addresses how gendered and undervalued reproductive labour is essential to economic growth and the realisation of international commitments such as the Sustainable Development Goals, particularly gender equality and inclusive growth. This Special Issue uses South Korea as a comparative case study due to its unique economic trajectory, rapid demographic ageing, stark gender inequalities, and limited social protection systems. The country’s long working hours, low fertility rate, and pronounced wage and care burdens on women illustrate how inadequate social reproduction support can threaten broader social and economic sustainability. The pandemic further intensified these issues, disrupting institutional supports and deepening inequalities. This Special Issue collectively examines how policies across different contexts either alleviate or exacerbate the tensions between productive and reproductive labour, using South Korea as a focal point for comparison. This comparative analysis highlights the need for structural reforms and cultural change to support effective social reproduction policies, emphasising that gender-equal leave, accessible childcare, and shared caregiving responsibilities are crucial for work-family balance and social well-being. South Korea’s experience illustrates both progress and ongoing challenges, offering valuable lessons on the limitations of market-driven approaches and the importance of resilient, state-supported family policies.
