Recently, House Budget chairman Paul Ryan, R-Wis., allowed journalists from CNN to attend a closed-door briefing that he held for fellow Republican lawmakers. One comment Ryan made during his presentation caught our eye. The Congressional Budget Office has this economic model where they measure the economy going forward, and they are now telling us that the entire economy crashes in the year 2037 because their computer simulation can't conceive of any way in which the U.S. economy can continue, Ryan said , according to the CNN report, which also included a video clip of the comment. We wondered whether Ryan was accurately describing what the CBO -- Congress’ non-partisan fiscal-analysis office -- was saying. We found that Ryan has a point about the peril facing the economy from the nation’s rapidly growing debt, but we also found that his comment was somewhat exaggerated. We turned to several economists, including liberals and conservatives, to see whether they knew of evidence that might support Ryan’s statement. They pointed to several documents that shed light on the claim. One was the CBO’s analysis of Ryan’s own budget roadmap, published in early 2010. The report compared Ryan’s proposal to a CBO model that takes the current baseline budget numbers and adjusts them to account for a number of policy changes, most of which are expected to be enacted. This can be considered an approximation of the status-quo. Analyzing this status-quo model, the CBO wrote that it is not possible to simulate the effects ... after 2058 because deficits become so large and unsustainable that the model cannot calculate their effects. (The CBO went on to write that, compared to the status-quo option, Ryan’s plan did a better job of bringing down the debt and promoting economic output.) Still, the year this economic model essentially blows up, according to CBO, is 2058 -- 21 years later than what Ryan said in the CNN clip. Subsequent estimates, with new data and revised methodologies, produced different -- and more dire -- conclusions. The CBO published a document called the Long-Term Budget Outlook in June 2010 and then revised it in August 2010. Like the analysis of Ryan’s plan, this study also used multiple models to analyze the future fiscal and economic picture. The CBO cautioned that one of these economic models breaks down if debt were continue to accrue indefinitely. The economic model used for this comparison is capable of estimating outcomes only under sustainable government policies, the CBO wrote, referring to policies that rein in the debt rather than letting it spiral out of control. Under the August revision, the CBO says this model functions through at least 2035. Paul Van de Water, a senior fellow at the liberal Center for Budget and Policy Priorities, said it’s plausible that the model could implode as early as the 2030s, though he added that other models analyzed by the CBO do not predict an implosion that soon. So the CBO has used a variety of models to analyze the future state of the economy, and some of them suggest serious problems for the economy within the next few decades. But there’s uncertainty about whether any of the CBO models specifically fail by 2037, as Ryan says, and his language -- that the entire economy crashes -- is probably a bit too apocalyptic given the uncertainties of the modeling. Our experts added a few other caveats. The model Ryan is referring to is based on the assumption that no policy changes are made to reduce the debt. Even though lawmakers have typically been loath to touch the main drivers of the nation’s debt burden -- entitlements such as Social Security and Medicare -- some economists said that it was unrealistic that politicians would simply let the economy implode rather than making changes to stave off that fate. This one is same category as shouting, ‘If you keep going like this, you're going to end up the Pacific Ocean’ to someone headed west from New Jersey, said Dean Baker, a liberal economist. It is absolutely true, but in an absurd way. Baker said that the CBO does long-term budget projections that assume that Congress never does anything even as the debt increases, pushing up interest payments, leading to ever-larger deficits. ... I'm not sure what Ryan thinks that he is showing by this. It is almost inconceivable that we would ever see anything like this. The models the CBO uses are just that -- models. Dan Mitchell, a senior fellow at the libertarian Cato Institute, said that he agrees that the economy is in danger, but not necessarily for the reasons laid out in the model. He thinks the general burden of government will be more of a defining factor than deficits or debt per se. The real issue is whether the CBO model makes sense, Mitchell said. I don't think it does because it is based largely on deficits and debt being the key determinants of economic performance. That's not true, though in extreme cases those factors can be very important. People are right to worry about the long run, even if CBO's methodology is a bit dodgy. So where does this leave us? We’ll start by listing the exaggerations in Ryan’s statement. First, he implies that there’s only one CBO model, glossing over the fact that the agency uses multiple models that have produced varying results. Second, Ryan predicts a collapse in 2037, but there’s considerable variation in the doomsday year depending on the model the CBO uses and the data it plugs into its calculations. Third, Ryan’s statement assumes that no change will be made from current policies before a collapse -- an assumption that’s unlikely. And fourth, his claim that the CBO’s computer simulation can't conceive of any way in which the U.S. economy can continue strikes us as an overstatement. In fact, the CBO finds lots of unpalatable scenarios if things get bad enough, but the agency doesn’t go so far as to suggest that the economy will simply cease functioning. Economies are far more complex than any single model, so just because a model stops working, it doesn’t necessarily mean that the economy will bring us back to hunter-gatherer days when the model stops working. What saves Ryan’s comment is that, despite his exaggerations, his general point is valid. The economists we spoke to agreed that that the nation’s current path of deficits and debt, if not altered, will become unsustainable. The issue is simply that under current law, the debt-to-GDP ratio soars so high that economic models break down, said J.D. Foster, a senior fellow at the conservative Heritage Foundation. The truth is that nobody really knows what would happen as the debt-to-GDP ratio pushes through 100 percent on the way to 200 or 300 percent. The models certainly are not capable of anticipating the effects. But you don't have to have an economic model to appreciate the clear picture of fiscal Armageddon. Generally, then, Ryan’s oversimplifications and exaggerations lead us to downgrade our rating, but his broader point about the perils of the debt for the nation’s economy remains accurate. On balance, we rate his statement Half True.
