Tax reform done right should be revenue neutral using standard CBO static analysis, but a dynamic model would predict a large revenue windfall from the overall increase in investment and economicefficiency.
However, it is the implicit costs of regulation that are more likely to generate overall negative outcomes and impair economicefficiency and growth, not to mention the inevitable unintended consequences of such regulation.
This is not because it is a shining example of efficiency and democratic accountability, but because its overalleconomic and fiscal outlook is, at the moment, surprisingly robust.
