The Brazilian experience with a general bank transactions tax

We have just been sent, a new paper entitled A new tax technology: The Brazilian experience with a general bank transactions tax.

This was a transaction tax that was killed off. Apparently:

"The special interests in Brazil finally got rid of their Transaction Tax because -- are you ready -- it was so dependable and automated, they could not cheat and evade like with VAT and income tax."

Indeed. This is an important element of transactions taxes, and the paper looks to be worth reading for those following the debates. Comments welcome.
