Deni Mazrekaj

Non-Stipendiary Research Fellow
Postdoctoral Researcher in Sociology and Social Demography, FAMSIZEMATTERS project

I am a postdoctoral researcher in sociology and social demography at the University of Oxford and an affiliated researcher at KU Leuven university in Belgium. I am particularly interested in the returns to schooling and the role of family environment in the development of the children’s adult outcomes. My primary goal is to conduct research with a substantial societal impact through causal effects that effectively inform policy and decision making. I am currently involved in the FAMSIZEMATTERS project, funded by the European Research Council (ERC). In this project, I investigate how family size affects the (re)production of social inequalities.

I completed my Ph.D. in economics on 15 November 2019 at KU Leuven. My Ph.D. chapters were primarily situated in labour economics, focusing on education economics and family economics. In my Ph.D. thesis titled “An Economic Perspective on School Dropout”, I employed quasi-experimental empirical methods on administrative population data to investigate the causal relationship between high school dropout and its potential predictors, labour market consequences, and policies.
