 In my country, the biggest challenges to tax policy are, one, I think we have a high informal sector that is not taxed. Second is that most of the business owners are not educated to understand the tax complexities. The government and our tax revenue authority should increase its taxpayer education, encouraging taxpayers to come out and pay taxes, register them, and to tell them the benefits of going formal. This has been an intense program but very educative. As a matter of fact, this has been one of the best experiences. 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. One of the things we have gained is the network. We have been able to get in touch with the professors now easily, especially if you have a challenge with any tax policy, any tax research. As a result of this winter school, you will see some good research ideas coming out very soon.
