If I was organized enough to send Christmas cards, I would take Richard Rahn off my list. I do one blog post to call attention to his Washington Times column and it seems like everybody in the world wants to jump down my throat. I already dismissed Paul Krugman’s rant and responded to Ezra Klein’s reasonable criticism. Now it’s time to address Derek Thompson’s critique on the Atlantic’s site.
At the risk of re-stating someone else’s argument, Thompson’s central theme seems to be that there are many factors that determine economic performance and that it is unwise to make bold pronouncements about Policy A causing Result B. If that’s what Thompson is saying, I very much agree (and if it’s not what he’s trying to say, then I apologize, though I still agree with the sentiment). That’s why I referred to Reagan decreasing the burden of government and Obama increasing the burden of government — I wanted to capture all the policy changes that were taking place, including taxation, spending, monetary policy, regulation, etc. Yes, the flagship policies (tax reduction for Reagan and so-called stimulus for Obama) were important, but other factors obviously are part of the equation.
The biggest caveat, however, is that one should always be reluctant to make sweeping claims about what caused the economy to do X or Y in a given year. Economists are terrible forecasters, and we’re not even very proficient when it comes to hindsight analysis about short-run economic fluctuations. Indeed, the one part of my original post that causes me a bit of regret is that I took the lazy route and inserted an image of the chart from Richard’s column. Excerpting some of his analysis would have been a better approach, particularly since I much prefer to focus on the impact of policies on long-run growth and competitiveness (which is what I did in my New York Post column from earlier this week and also why I’m reluctant to embrace Art Laffer’s warning of major economic problems in 2011).
But a blog post is no fun if you just indicate where you and a critic have common ground, so let me identify four disagreements that I have with Thompson’s post:
(1) To reinforce his warning about making excessive claims about different recessions/recoveries, Thompson pointed out that someone could claim that Reagan’s recovery was associated with the 1982 TEFRA tax hike. I’ve actually run across people who think this is a legitimate argument, so it’s worth taking a moment to explain why it isn’t true.
When analyzing the impact of tax policy changes, it’s important to look at when tax changes were implemented, not when they were enacted (data on annual tax rates available here). Reagan’s Economic Recovery Tax Act was enacted in 1981, but the lower tax rates weren’t fully implemented until 1984. This makes it a bit of a challenge to pinpoint when the economy actually received a net tax cut. The tax burden may have actually increased in 1981, since the parts of the Reagan tax cuts that took effect that year were offset by the impact of bracket creep (the tax code was not indexed to protect against inflation until the mid-1980s). There was a bigger tax rate reduction in 1982, but there was still bracket creep, as well as previously-legislated payroll tax increases (enacted during the Carter years). TEFRA also was enacted in 1982, which largely focused on undoing some of the business tax relief in Reagan’s 1981 plan. People have argued whether the repeal of promised tax relief is the same as a tax increase, but that’s not terribly important for this analysis. What does matter is that the tax burden did not fall much (if at all) in Reagan’s first year and might not have changed too much in 1982.
