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 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 using applied empirical methods. Her recent research examines labour market inequalities, particularly in relation to gender and immigration, the effectiveness of transparency legislation and family-friendly policies, the relationship between labour market institutions and fertility, and the role of household interactions in shaping labour supply decisions. She has also examined peer effects in young adults’ academic and economic performance and their co-residence with parents, which are linked to fertility, mobility, and later labour market outcomes. To learn more about Dr Kaya's 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, Scandinavian Journal of Economics, Journal of Economic Behavior and Organization, Canadian Journal of Economics, and Economica, among others. It has also received the Etta Chiuri Best Paper Prize (2014), the Turkish Economic Association Postgraduate Research Award (2008), commendations for Collaboration and Methodology at the ONS Research Excellence Awards (2025), and nominations for the People’s Choice Award at the ONS Research Excellence Awards (2020 and 2025).
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.
