These days virtual publication matters more than actual, so far as readership is concerned. But I'll nonetheless note that the article I co-authored last year with Joe Bankman, "Piketty in America: A Tale of Two Literatures," has now officially come out. It's at 68 Tax Law Review 453-516 (2015).
The online version, differing little from the final one, is available here.
The Tax Law Review issue (vol. 68, #3) in which it appears contains all five of the papers from the symposium on Piketty's book, Capital in the Twenty-First Century, which took place here at NYU just over a year ago. The others are by Gregory Clark (with Neil Cummins), Wojciech Kopczuk, Suzanne Mettler, and Liam Murphy. There's also a response by Piketty that mainly covers some aspects of what he had in mind with the book. He appears to have no quarrel with our commentary.
