Higher Taxes Won’t Reduce the Deficit

In theory, raising taxes should be a way to increase revenues that can be used to reduce the federal deficit. In reality, increased tax revenues not only do not reduce the deficit, they lead to increased spending :

In the late 1980s, one of us, Richard Vedder, and Lowell Gallaway of Ohio University co-authored a often-cited research paper for the congressional Joint Economic Committee (known as the $1.58 study) that found that every new dollar of new taxes led to more than one dollar of new spending by Congress. Subsequent revisions of the study over the next decade found similar results.

We’ve updated the research. Using standard statistical analyses that introduce variables to control for business-cycle fluctuations, wars and inflation, we found that over the entire post World War II era through 2009 each dollar of new tax revenue was associated with $1.17 of new spending. Politicians spend the money as fast as it comes in—and a little bit more.

We also looked at different time periods (e.g., 1947-2009 vs. 1959-2009), different financial data (fiscal year federal budget data, as well as calendar year National Income and Product Account data from the Bureau of Economic Analysis), different lag structures (e.g., relating taxes one year to spending change the following year to allow for the time it takes bureaucracies to spend money), different control variables, etc. The alternative models produce different estimates of the tax-spend relationship—between $1.05 and $1.81. But no matter how we configured the data and no matter what variables we examined, higher tax collections never resulted in less spending.
