Tax Cut Followup

This is arcane, but I guess I need to follow up on my post last night about the CBO’s report on extending tax cuts. I think I’ve figured out what’s going on.

The CBO chart is below, and it doesn’t seem to match the data in Table 4. But it does, sort of. Take the bar for full extension of tax cuts with a weak labor response. According to Table 4, its effect in 2020 is to reduce real GNP by 1.6%. That’s if everyone assumes there’s no response. But if we assume that government spending will be reduced after 2020, a lifecycle model predicts that the net effect of extension is only -1.4%. If we assume a tax increase after 2020, the lifecycle model predicts that the net effect is -0.8%.

Now average all those together and you get -1.26%. That rounds to -1.3%, and that’s what’s shown in the chart. If you average all the other options they also match the chart.

Is this simple arithmetic averaging legit? Beats me. And I’m not even sure who to ask. But apparently that’s what they did.

One more thing, though. The CBO model suggests that in all cases, a policy response to full extension of the tax cuts reduces the long-term damage. However, a policy response to extension of just the middle-class cuts increases the long-term damage or has only a tiny effect. This seems like a very strange result. Why does a policy response (either lower spending or higher taxes) have a strongly positive effect in one case and a bad or negligible effect in the other? Again, I’m not even sure who to ask. But it seems odd even if you’re a supply side die hard.

SIX TRUTHS

Reclaiming power from those who abuse it often starts with telling the truth. And in "This Is How Authoritarians Get Defeated," MoJo's Monika Bauerlein unpacks six truths to remember during the homestretch of an election where democracy, truth, and decency are on the line.

Truth #1: The chaos is the point.

Truth #2: Team Reality is bigger than it seems.

Truth #3: Facebook owns this.

Truth #4: When we go to work, we're in the fight.

Truth #5: It's about minority rule.

Truth #6: The only thing that can save us is…us.

Please take a moment to see how all these truths add up, because what happens in the weeks and months ahead will reverberate for at least a generation and we better be prepared.

And if you think journalism like Mother Jones'—that calls it like it is, that will never acquiesce to power, that looks where others don't—can help guide us through this historic, high-stakes moment, and you're able to right now, please help us reach our $350,000 goal by October 31 with a donation today. It's all hands on deck for democracy.
