Here are the slides that I used last Thursday for my lunch talk at the National Tax Association's 46th Annual Spring Symposium, in Washington, DC. I called the talk "Ten Observations Concerning International Tax Policy." I am planning to publish and/or to post in some way, and then to link here, a written-out version of my full remarks using these slides, but the mechanism for that is still being determined.
UPDATE: It looks as if the talk will be appearing in Tax Notes, perhaps on or about June 20. I'll be publishing it, expressly as a recent talk that I gave, in "Current and Quotable," rather than turning it into an article.
