 My story of change is five years ago when I was doing my PhD, none of the data was available. The story of change has been the ease with which researchers can then access data for research. My story of change has been the improvement of technical capabilities to inform tax policy which betters the social welfare of the ordinary Zambians. Being able to produce recommendations and outcomes that help with the whole being of the country. My story of change is having to apply the skills that I gained during the winter school to be able to impact in the research that I do at the Kenya Revenue Authority. My story of change has been basically improving my own techniques and level of understanding of micro simulation but also the ability to generate cost effective data and evidence that has been very critical in informing and changing our policies in Zambia. When I started the PhD program I didn't know anything about the micro simulation model. I'm now giving support and providing capacity building trainings to experts in sub-Saharan countries. On living wider I since joined the African Darwin Bank but I've also been a fellow at Cornell University. I think wider really gave me an incredible basis for achieving all of these things. My story of change has been to make my research and policy analysis quite simpler and quicker. My story of change is about the ability to communicate my research, share it with a much broader audience, policy makers in the Global South especially. The work that we have done will make significant input into the current policy debate. The ultimate objective is to build up this in-country community of people who are interested in and capable of doing kind of rigorous tax policy analysis, rigorous thinking about the effects of possible reforms. 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.
