The excerpt from his paper cited below outlines his methodology for deriving the the macro-dynamic effects he says are missing from the TPC analysis (he also looks at the same micro-dynamic issues that the TPC does include - but his main argument concerns macro-effects).

He calculates the effect on revenue of assuming a 3, 5 and 7 GDP effect over a decade - but concludes that 3 percent is the most reasonable figure. To justify this he relies on a paper by John Diamond of Rice University which sets out the results of simulations of the Romney tax plan using a widely used general equilibrium growth model. This model produces a 5 percent estimate which Rosen adjusts down since it assumes that all the Bush tax cuts expire, which Rosen thinks leads to an inflated GDP impact.

Since Rosen's analysis depends crucially on the Diamond study it is added as a supportive node to this one - as are other studies that claim a significant macro-dynamic growth effect.
