Teams and roles for Ezgi Kaya
Senior Lecturer in Economics
Overview
Dr Ezgi Kaya is a Senior Lecturer (Associate Professor) in Economics at Cardiff Business School, a fellow at the Global Labor Organization (GLO) and a member of the ESRC Peer Review College. She is also a co-investigator of the GW4 Maternity Leave Network. Between 2023 and 2025, she was a Research Fellow funded by ADR UK (Administrative Data Research UK), an Economic and Social Research Council (ESRC) investment (part of UK Research and Innovation).
With expertise in labour economics and economic demography, Dr Kaya works with large scale survey and administrative data and applied methodologies. Her recent research projects explore labour market inequalities, particularly in relation to gender and immigration, the effectiveness of transparency legislation and family-friendly policies in shaping labour market outcomes, the relationship between labour market institutions and fertility, and the role of assortative mating and household interactions in shaping the labour supply behaviour of married women and men. She has also conducted research on identifying peer effects in academic and economic performance, as well as the co-residence decisions of young adults with their parents—decisions often linked to fertility, mobility, and future labour market outcomes. To learn more about Dr Kaya's current research, visit her website.
This work has been featured widely across the media and published in high-quality peer-reviewed journals, including International Economic Review, Oxford Bulletin of Economics and Statistics, Journal of Economic Behavior and Organization, Canadian Journal of Economics, Economica, IZA Journal of Development and Migration, Oxford Economic Papers, Industrial Relations, and International Labour Review, among others. It has also received the Etta Chiuri Best Paper Prize (2014) and the Turkish Economic Association Postgraduate Research Award (2008).
Dr Kaya received her PhD in Economics from the IDEA Graduate Programme at Universitat Autònoma de Barcelona in 2014. For her latest CV, visit her personal website.
