I have just completed what might be a full draft of my book-in-progress, Fixing The U.S. International Tax Rules. It took 4 years and 4 fresh starts - whereas usually, once I have a book clearly in mind, I can write it in a few months. The total damage is about 100,000 words, which is perhaps a bit on the long side. But even at that length, there were a number of topics that I needed to keep fairly brief. It is much more directed to how we should think about international tax policy than to pitching a particular solution, although I do try to relate the ideas discussed to concrete implementations.
It's not quite a completed draft just yet, as I need to read the whole thing over again, with an eye to its unity, consistency, and non-repetitiveness, among other key attributes. The constant reloads and start-and-stop character of the process make this especially necessary, although they have also induced me to do a lot of re-reading and editing as I went along.
I'll be presenting the book at a conference in Hebrew University this June. (My 3 discussants are probably glad to know that they will see it soon.) And I have not as yet committed to a publisher. I won't be posting it on SSRN, but hopefully it will be out as soon as 2014.
Some, but not all, of what I consider its more novel aspects are foreshadowed in articles that I have published over the last few years on foreign tax credits and U.S.corporate residence electivity. But I have rethought some of the ideas in those articles, and the book is almost 100% new work, as opposed to being a cut-and-paste job.
