There is an important procedural obstacle to funding public investments — a process of scoring the economic effect of legislation. This process is driven by assumptions that are biased in favor of low taxes and against public investment. This budget scoring process systematically underestimates the benefits of public investment and systematically overstates the costs of taxation and debt. The power of the budget scoring process to derail legislation that would fund public investment is amplified by a think tank, the Penn Wharton Budget Model (PWBM). The PWBM assumes that taxes and debt have devastating effects on economic growth and assumes away much of the benefit of public investment. These strong assumptions are not consistent with the breadth of estimates in relevant empirical literature.
The director of the PWBM, Kent A. Smetters, recently responded to criticisms. This article summarizes the original critique of flaws in the PWBM analysis and discusses PWBM’s response (or non-response) to each substantive point. Readers may wish to review the original critique before proceeding.
