The issue you are raising has been discussed in The Economist and in other publications. I think that some governments, including our own, have voiced concerns about this. The OECD has undertaken some very serious and very ambitious work to determine what could be done in this regard.
As I mentioned, if we take on this kind of problem, we should not just consider one or two solutions, but rather a set of solutions. This will take a little time because it is fairly complicated. Lastly, since this is being done by the OECD, an agreement between the countries is required. It may or may not lead to a multilateral instrument. It is much too early to say.
