A few years ago, I concluded that the magnitude of our looming fiscal problem was so enormous that higher taxes were inevitable--and that was long before the recent crisis made matters vastly worse. Moreover, I concluded that the magnitude of this tax increase is so great that it would seriously cripple the economy if accomplished through higher rates on an already dysfunctional income tax system. Reluctantly, I concluded that a value-added tax (VAT) is the best way to raise the revenue that would, in any case, be raised.
When I first made this suggestion in a Los Angeles Times article in 2004, I was building on a large body of tax analysis showing that the VAT is the best known way of raising revenue. When I say "best" I mean that it raises large revenues from low rates and has minimal disincentive effects. In economists' speak, it has a very small dead weight or welfare cost--the economic output lost by the tax over and above the revenue collected.
... Back in the early 1980s, practically every leading conservative economist supported a VAT for the United States. Norman Ture, one of the godfathers of supply-side economics, and Murray Weidenbaum, chairman of the Council of Economic Advisers under Ronald Reagan, wrote many articles, books and papers supporting the VAT. The conservative American Enterprise Institute published a book in 1987 saying that the VAT was the key to deficit reduction.
Perhaps the strongest evidence that the VAT was considered the conservative tax reform is that it is the foundation of the flat tax, which is still supported by practically every serious conservative tax reformer.
... [A flat tax] is not the only case of conservatives supporting a VAT when it suited them to do so. Back in 1992, former California Gov. Jerry Brown proposed a VAT plus a flat rate income tax and this was widely hailed by supply-side economists such as Arthur Laffer and Gary Robbins. More recently, Sen. Jim DeMint, R-S.C., introduced legislation (S. 1240) to establish a business consumption tax that is, in essence, a VAT.
