1. Slide 2: Why care?
a. Beholden to China, yes, but they are more beholden to us – they are only one of many bondholders, but almost all their bonds are dollar-denominated.
b. Intergenerational transfers can occur via voluntary saving, involuntary taxing (FICA) and debt issued outside our economy. Don't focus on one to the exclusion of the others. Futhermore, ALL retirement at the societal level has to be financed on a pay-as-you-go basis, since what we consume are services, and they can't be saved.
2. Slide 9: Revenues vs Spending
a. Spending and revenue are distorted in the graph due to the sharp decline in GDP, from which we have yet to recover. So you need to incorporate changes in the numerator and not just the denominator. One way to do that is to use potential GDP. (This same issue applies elsewhere.)
b. On the revenue side, reliance on income taxes accentuates the impact of busts and booms. Graphing against the gap between current and potential GDP would highlight that.
3. Slide 13: Tax Expenditures
a. A focus on tax rates obscures other tax rules (carried interest) that affect actual payments, particularly for those in jobs amenable to relabeling compensation to be other than wages.
b. Perhaps in the discussion of the slide, but it's worth noting that some of the tax expenditures are only relevant if you have enough income to itemize deductions.
4. Slide 16: Healthcare costs
a. Projections of social security expenditures are fairly robust, because you can use replacement rate x GDP x claimants / GDP, and demographic projections are robust while the replacement rate is fixed by law.
b. Projections of healthcare are very dependent on projections of healthcare costs. While we have not been successful in the past in controlling costs, the rate of increase has slowed in recent years. If that continues – and since there's little consensus on why the increase has slowed, we simply don't know – then this graph overstates future levels, potentially by a large percentage of GDP
5. Slide 17: R&D and infrastructure
a. We ought to be spending less on infrastructure today, depreciation versus new construction of roads and the like. That it's fallen by half doesn't tell us what we need to know.
b. Accounting for R&D is hard. For example, nuclear weapons programs don't yield private benefits and should be excluded. That was more important in the 1950s, muddying what we might learn from comparisons.
6. Slide 18: Unfunded obligations
a. These are subject to the discount rate and number of years over which projections are made. Social security goes out 75 years – sensible?
b. Furthermore, no one contemplates repaying all government debt. What matters are changes sufficient to stabilize debt.
c. To communicate with lay people, what is the equivalent steady-state change in taxes as a percentage of GDP required to accomplish this?
7. Slides 21-22: Simpson-Bowles? Let's hope not – I've never figured out why people talk about it. Furthermore, when matters, not just how much. Should we be striving to raise taxes and lower expenditures while unemployment remains far, far above historic levels?
8. Slide 25: Wish list.
a. Skimpy on details.
b. The devil rules therein.
9. Slide 26: Social security.
a. All of this presumes that somehow social security ought to be a boat that rides on its own bottom. As an economist, there's no reason for that.
b. In addition, are benefits so generous that they ought to be cut? The lower CPI adjustment does that, and since retirees aren't average – they consume more healthcare – the overall inflation rate already understates the inflation they face.
c. Raising the cap on social security payments only affects higher income individuals; depending on the level, means testing potentially also affect higher income individuals.
d. Raising the retirement age certainly enhances revenue while lowering outlays, but is offset by higher rates of disability at older ages. Since those who are poor are more likely to be disabled, a blanket increase could result in those most vulnerable falling through the cracks.
e. Social security is intended to provide security, as it insures against inflation and swings in returns on stocks and bonds. Private accounts do not provide those functions. Nor would private accounts add to national savings. They also face phase-in issues.
10. Slide 27: Healthcare reforms
a. Several of these proposals parallel those for Social Security and suffer from the same defects.
b. Cost control ultimately requires saying "no" – but current legislation provides very little ability to limit treatments that are not proven more effective than less costly alternatives. In addition, there are no mechanisms to encourage the terminally ill to seek hospice care rather than hospitalization. These are challenging technically, as well as in politics and ethics. Nevertheless, we fool ourselves to think that co-pays and tougher reimbursement guidelines will be adequate, except as they mean that less well-off individuals do without.
11. Slide 29: Sequestration
a. I have yet to see any proposal for a grand bargain that reflects sensible economic analysis.
