 I really really enjoyed how we can use tax administrative data to better understand inequality. So how do we use tax data to be able to simulate different situations where government can use tax as a base to be able to redistribute income or resources across society to ensure equity. The highlight for me was really how to estimate the elasticity of taxable income. At the second level I think that this new concept for example profit shifting, this is something that I wasn't aware of. And this workshop really was an opportunity for me to learn more about. And finally I think that this workshop was really an opportunity in terms of interaction with further researchers. I've gained a lot from this winter score. For example for the case of tax evasion. And also the thing that I've gained is that it's not only the magnitude of tax give that matter but the direction. I remember the lecture concerning the taxation and informality. I enjoyed that lesson especially on these three views of informality. It unlocked my understanding and view concerning taxation and informality. One of the things we have gained is the network. You're able to get in touch with the professors now easily, especially if you have a challenge with any tax policy, any tax research. The professors here are very very good and they have been able to give us the academia side plus the research side. We have met academia and research in the intersection. As a result of this winter score you will see some good research ideas coming out very soon.
