Thank you very much for these questions. Again, we do not have any estimates. The only estimate we have is based on microdata. We reported to the G-20 last year that the progress in terms of transparency has yielded $15 billion euros over the past three years to some G-20 countries. It's not a rough estimate because it comes from the agencies, but it's pretty small indeed compared to the figures we can find here and there. As you've said, what is behind that is not only the money you collect but the fairness that you introduce in the tax system. If some can hide without any risk and can avoid or evade, then this has an impact on the level of compliance in the country. There is a question of fairness and of undermining the trust in the fairness of the tax system.
Finally, is there evidence of correlation between the rise in the tax rates or the tax base and evasion? The answer is no. There is none, except the empirical evidence, except maybe in the area of indirect taxes on VAT. It is generally accepted, although I cannot refer to a precise survey, that 22%, 23%, and 24% of VAT has a massive impact on compliance with the tax. Obviously the more you ask from the taxpayers, the more likely they are to try to evade taxes. This needs to be put in the context of the efficiency of the government and what they get in exchange for the taxes they pay. That's where you can explain that the level of compliance in some countries with high taxes, such as the Nordic countries in Europe, is much higher than in some other countries where the tax level is lower.
