I'm familiar with the theory, however I've never seen a good treatment of how this works with multiple countries. The income and capital gains taxes only apply to shareholders residing in the US. Maybe some of the corporate tax could be considered a fair "rent" price for using the nations resources? But I'd have to see a real model to be sure. It's still unclear to me whether (a) nations have conflicting goals when it comes to taxation (they don't when it comes to free trade, so maybe they don't with tax either) and (b) what the optimal corporate tax rate is.
