Until October 2018 Holly was Director of EUROMOD, the tax-benefit microsimulation model for the European Union which celebrated its 20th anniversary in 2016. She has more than 30 years of experience of designing, building and using such models – the UK model she helped to develop in the mid-1980s was one of the very first anywhere – and has coordinated more than 10 international EUROMOD-related projects as well as participating in many more. She has co-authored/edited 5 books on microsimulation modelling and published widely in economics and social policy journals.
Her longstanding research interests include the gender effects of redistribution policy and child poverty measurement and analysis. Her current interests also include extending microsimulation capacity to developing countries and to groups without access to such models.
