First, it is important to remember that although the total package is scored as costing almost $900bn over two years, almost everything in this package simply leaves in place current tax rates and spending. The biggest portion of the tax cut continues the tax rates put in place by President Bush in 2001. The continuation of these tax cuts, including a lower estate tax rate, accounts for almost $400bn of the $900bn.
Adding in the cost of a technical fix to the Alternative Minimum Tax, which is done every year, and the continuation of a series of smaller tax breaks, brings the total to $670bn. This portion of the package buys exactly zero stimulus, since it simply amounts to continuing tax policies already in place. Had these tax breaks not continued, it would have been a drag on growth, but their continuation does not provide any additional momentum to the economy. The $60bn cost of extending unemployment insurance for another year can also be put in this category.
