 My story of change, my story of change, my story of change, my story of change. Five years ago when I was doing my PhD, none of the data was available. There were lots of problems. Nobody knew how to work with it. And we come to a point now where we can present our work from multiple countries at international conferences and there's really something to be proud of. So tax administrative data can be sensitive and it can be large and it needs to be taken or treated with care and sensitivity and requires researchers to come in and support and work with the revenue authority to produce research that's relevant to them and can be informing policy. Our work with the Zambian Revenue Authority on VAT and tax gap research have given them an insight into the research that can be done with tax administrative data. The research is always going to be collaborative. So it's always hand in hand with the revenue authority researcher, with somebody in the Ministry of Finance. Part of the story is not that we always do the research ourselves. Part of the story is that we empower researchers within the country, within the revenue authority to be able to produce their own work. And it's definitely a cascading effect, learning from your neighbour. It's a lot of south-south collaboration. You can take learnings from one country and actually replicate that work somewhere else. What I want to see is young people get involved in research in their own country. They know the context better than I do and they'll know how to take it forward within their structures and their contexts.
