Wonky teaser for my FAT versus FTT article

Bruce Bartlett's newly posted Tax Notes column criticizing financial transactions taxes (FTTs) reminded me that, while James Tobin is often considered the FTT's grandfather due to his 1970s advocacy of a tax on currency exchange transactions, John Maynard Keynes offered a seemingly very similar rationale for a tax on securities trades. However, I may argue in my paper that, insofar as the rationales can be teased apart, Keynes' actually stands up better today than Tobin's.
