Hi, I'm Josue Ortega, a lecturer in economics at Queen's University Belfast.
My research studies how to allocate scarce resources fairly and efficiently, both theoretically and using data. Applications of my research include the design of algorithms to assign pupils to schools, divide land among nations, or the analysis of the effects of online dating. My research is interdisciplinary and I often write articles in collaboration with computer scientists and sociologists.
I have published in Games and Economic Behavior, the Journal of Mathematical Economics, Social Choice and Welfare, Economics Letters and Mathematical Social Sciences. My research has been covered by The Economist, the Times, the Financial Times, the MIT Technology Review and Forbes, among others.
I obtained my PhD from the University of Glasgow in 2017 under the supervision of Hervé Moulin.
