Perry’s economic analysis of his tax plan should be retracted
I apologize for continuing to harp on this Rick Perry study, but I just can’t help myself. As I mentioned in an earlier post, the first thing that really jumps out at you is the breathtaking intellectual dishonesty. But beyond its complete inconsistency with Perry’s ideology and professed objectives, the analysis simply doesn’t make sense. Here are a few examples:
1) GDP growth is impossibly high: Remember that Heritage Foundation analysis of the House Republican 2012 Budget, the one that predicted economic growth and unemployment at levels most economists considered impossible? Well, John Dunham and Associates’ (JDA) projections underpinning the analysis of Perry’s tax plan are even more impossibly higher! The Heritage analysis found that the average annual real growth rate from 2014-2020 would be about 3.1 percent. JDA is predicting that under Perry’s plan, it would be 5.3 percent. Reality’s overrated anyway, right?
2) Double counting: The analysis claims that “overall income is based on growth in nominal GDP and population (pg. 4).” See the problem here? Yeah, that’s right, nominal GDP already takes into account population growth. We checked their numbers, and it does appear they grew income by both GDP and population, so it doesn’t seem to be just a typo.
3) Other weird stuff: Check out the qualified dividends forecast from Table 2 of the analysis. From 2016-2019 dividends grow at an average 12.6 percent, including 13.2 percent in 2017, 14.0 percent in 2018, and 8.2 percent in 2019. And then 2020? Whoops. According to this forecast, qualified dividends in 2020 will be exactly the same as in 2019, to the dollar. Same thing with 2011 and 2012. The chance that that’s not a mistake is about zero.
4) Optional or mandatory?: It is unclear whether JDA modeled an optional flat tax or a mandatory flat tax as a replacement for the current income tax. The campaign maintains that JDA did model optionality. But their stated methodology does not mention how they modeled which taxpayers would choose which system, and their description of the proposal—”a 20 percent flat rate for both personal income taxes and corporate income taxes”—also makes no mention of having a choice between the current system and the new system.
We contacted the Perry campaign in regards to these numerous errors and omissions, but have yet to hear back. These aren’t minor problems – the entire analysis is suspect and the Perry campaign should retract these numbers.
