Between banging out pages of a paper due tomorrow, I talked with Arjun about investing. I mentioned Tweedy, Browne, which is where Buffett used to invest when he was in NYC. Their Research & Reports section is worth a complete read.
I'll post the paper tomorrow, it has a basic history of taxation in the US, the rise of income tax, the subsequent rise of tax evasion and tax competition, followed up with a quick analysis of the OECD's "Tax Cooperation" strategy.
