Southern Europe has seen remarkable turnarounds in female labour force participation (FLFP) over the past four decades. In Turkey, however, scores of women have yet to join the labour force. To address this 'Turkish puzzle', we present comparative data on women's work in Portugal, Spain, Italy and Greece (SE-4) and Turkey. Through Qualitative Comparative Analysis, we identify the factors behind rising FLFP in Southern Europe to explore the prospects for a steeper rise of FLFP in Turkey. We reveal two causal pathways to rising FLFP: (i) left party rule, or (ii) combinations of higher levels of take-up of early education and care, higher levels of tertiary education among women and larger size of service sector employment.
