The entire infographic is too big to post here, but here’s how Andrew Stocking and Maureen Costantino portray America’s energy sources and uses:

One of the most notable features is the absence of any link from natural gas to transportation (some natural gas is used in transportation, of course, but not enough to make the cut for this image). Given the ever-growing divergence between oil and natural gas prices, I wonder whether that will still be true a decade from now? Or will someone finally crack the natural gas to transportation fuel market in a big way?

Budget experts are waging a spirited battle over the Medicare changes that helped pay for 2010’s health reform. In April, Chuck Blahous, one of two public trustees of the program, released a study arguing that the Affordable Care Act (ACA) would increase the deficit by at least $340 billion by 2021, a sharp contrast from the $210 billion in deficit reduction estimated by the Congressional Budget Office (CBO).

Chuck bases his estimates on several factors, but the item that has garnered the most attention is his charge that the ACA’s spending cuts and revenue increases in Medicare Part A are being double counted: once to help pay for the ACA’s coverage expansion and a second time to improve the finances of the Part A trust fund, whose predicted exhaustion was delayed by several years.

Chuck notes that those resources can be used only once: They can either offset some costs of health reform or strengthen Medicare, but not both. He believes those resources will ultimately finance additional Medicare spending and thus can’t offset any health reform costs. For that reason, he concludes that the ACA would increase deficits, rather than reduce them.

That argument inspired a host of commentary from leading budget experts, ranging from denunciation to affirmation. See, for example, Jeffrey Brown, Howard Gleckman, Peter Orszag, Robert Reischauer (as quoted by Jonathan Chait), and Paul Van de Water, and a follow up by Chuck and Jim Capretta.

Why does this dispute exist? It can’t just be politics. If it were, we’d have double-counting disputes about every program. But we don’t. We thus need an explanation for why this debate has erupted around Medicare Part A, which provides hospital insurance, but not around other programs. Part A is not unique in controlling spending by a “belt and suspenders” combination of regular program rules (the “belt”) and an overall limit (the “suspenders”). Such budgeting also applies to Social Security, Medicare Parts B and D (which cover physician visits and prescription drugs), and the National Flood Insurance Program. The federal debt limit acts as “suspenders” for the entire budget. But none of those give rise to double-counting disputes.

That suggests that there is something unusual—perhaps flawed—about budgeting for Medicare Part A. To see what that is, it helps to boil the dispute down to two basic questions about programs subject to “belt and suspenders” budgeting.
First, can spending reductions or revenue increases in the program offset spending increases or revenue reductions in other programs? In short, can budget savings pay for other programs? Or must they stay within the program itself?

Second, would hitting the overall budget limit affect program operations? In other words, do budget savings extend the period during which the program can operate at full capacity? Or is the limit operationally toothless?

As shown above, policymakers have answered these questions differently for different programs (for further details, see the appendix).

This comparison reveals the unique feature of Medicare Part A: It is the only one of these programs that allows budget savings to pay for other programs and has a trust fund with real operational teeth. It alone answers Yes to both questions. That is why Medicare Part A is the only program that creates the possibility of double counting and suffers from the reality of a double-counting dispute.

Double counting isn’t possible in Social Security or the NFIP because budget rules require that savings stay in the program. It isn’t possible for the budget as a whole since there are, by definition, no other programs to fund. And double counting isn’t possible in Medicare Parts B and D because its trust fund does nothing to limit operations.

But double counting is possible in Medicare Part A. That happens whenever someone claims that the health reform legislation both reduces deficits and provides additional resources to Medicare Part A. I will leave it to others to adjudicate whether any health reform proponents committed that error. I will note, however, that every budget expert, including Chuck Blahous, agrees that CBO didn’t do so (its baseline ignores the trust fund, so savings reduce deficits and have no effect on program operations).

Bottom line: The peculiar budget rules for Medicare Part A make it possible for analysts, pundits, and policymakers—whether willfully or inadvertently—to double count budget savings in Medicare Part A. That needless confusion is a significant flaw. To correct it, Congress could adopt the budget practices it uses in Social Security, Medicare B & D, or the NFIP. In a follow-up post, I will examine the pros and cons of these alternatives.

 Appendix: How “Belt and Suspenders” Budgeting Works

In Medicare Part A, spending is determined by rules about benefit eligibility and provider payment rates. If the Hospital Insurance (HI) trust fund balance falls to zero, however, spending faces a separate, hard limit: payments can’t exceed receipts. Program operations would thus be disrupted if the trust fund became exhausted. Congressional budget rules ignore the trust fund and assume that spending will continue at scheduled levels regardless of its balance. Under that approach, any spending reductions or revenue increases in Medicare Part A generate new budget resources that can be used to pay for changes in other programs.

Social Security operates differently. It faces the same operational limitations as Medicare Part A if its trust fund balance falls to zero. But Congress enacted special rules that forbid any Social Security spending cuts or revenue increases being used to pay for other programs. Such savings therefore accrue in the trust fund. The trust fund thus matters for operations, and savings cannot be directed to other parts of the government. (Social Security actually involves two programs, one for retirement and one for disability, and two corresponding trust funds; these comments apply equally to both.)

Medicare Parts B and D operate in a third way. Like Part A and Social Security, their spending is determined by eligibility and payment rules and gets paid out of a trust fund (the Supplementary Medical Insurance or SMI trust fund). But that fund has unlimited right to draw on general tax revenues. A zero balance thus results in general revenue transfers, not operational disruptions. Reforms don’t increase the life of the trust fund (since it can never go broke), and savings can be used to finance other programs.

The National Flood Insurance Program operates in yet another way. The NFIP is required to finance itself out of its insurance premiums; if its costs exceed those premiums, it can borrow from the federal government up to a specified limit. Once that limit is reached, payments can’t exceed its revenues, and operations are disrupted. The borrowing limit thus acts like the trust fund balance in Medicare Part A or Social Security, except that it allows the program to go a fixed amount into the red.

Congressional budget rules treat the borrowing limit as a fundamental restraint on NFIP spending. If the program is expected to run annual deficits, as it is today, those deficits exist only until the borrowing limit is reached. After that, the NFIP is projected to break even, with spending restrained to equal revenues. If Congress reduces the annual deficits in the NFIP (e.g., by increasing premiums), those savings allow the program to operate longer before reaching its borrowing limit. Any temporary budget savings thus get offset by increased NFIP spending in later years. Those temporary budget savings thus cannot be used to offset spending in other programs (unless hitting the borrowing limit is pushed beyond the budget window).

The debt limit, finally, acts as a “suspenders” restraint on deficits incurred by the entire federal budget. As we saw last summer, the debt limit threatens real operational restraints. Spending reductions and revenue increases can delay when the debt limit is reached. But they cannot be used to pay for other programs. Why? Because there are no other programs. The debt limit thus operates like the Social Security trust fund: it imposes an important operational restraint, and budget actions used to avoid it cannot pay for other programs.

Not always, of course. Many all-you-can-eat buffets continue to thrive even though the marginal cost of the next chicken nugget is zero. And many content providers manage to stay in business by selling radio, TV, or display ads against the free content users enjoy.

But all too often, a zero price attracts bad customers and encourages excessive consumption. Marco Arment of Instapaper, for example, discovered that a zero price attracted “undesirable customers” for his app. And AT&T famously discovered that offering unlimited iPhone data could overwhelm its capacity.

Thanks to Ken Besinger of the Los Angeles Times, we now have another juicy example: the lifetime passes that American Airlines sold to a small group of customers:

There are frequent fliers, and then there are people like Steven Rothstein and Jacques Vroom.

Both men bought tickets that gave them unlimited first-class travel for life on American Airlines. It was almost like owning a fleet of private jets.

Passes in hand, Rothstein and Vroom flew for business. They flew for pleasure. They flew just because they liked being on planes. They bypassed long lines, booked backup itineraries in case the weather turned, and never worried about cancellation fees. Flight crews memorized their names and favorite meals.

Each had paid American more than $350,000 for an unlimited AAirpass and a companion ticket that allowed them to take someone along on their adventures. Both agree it was the  best purchase they ever made, one that completely redefined their lives. …

But all the miles they and 64 other unlimited AAirpass holders racked up went far beyond what American had expected. As its finances began deteriorating a few years ago, the carrier took a hard look at the AAirpass program.

Heavy users, including Vroom and Rothstein, were costing it millions of dollars in revenue, the airline concluded.

How did things go wrong? American Airlines miscalculated how pass holders would behave:

“We thought originally it would be something that firms would buy for top employees,” said Bob Crandall, American’s chairman and chief executive from 1985 to 1998. “It soon became apparent that the public was smarter than we were.”

In economic jargon, American fell victim to both adverse selection and moral hazard. What customer wants to buy an unlimited, lifetime pass? One who’s happy to spend a great deal of time flying about in first class with friends, family members, or a random person they just met at the gate. And how will they behave? As though first class seats are costless, easy to book, free to cancel, a great gift for friends and strangers, and even, in some cases, as a revenue source.

What happened next shouldn’t be surprising. First, the passes went through a death spiral with American raising the price in a vain effort to make them profitable. When last offered, a single pass cost $3 million and was purchased by a grand total of nobody. Second, American sicced its “revenue management executives” on the most flagrant of the frequent flyers. As a result, several had their passes revoked for misuse. And American faces some lawsuits that make one wonder whether it crossed the line in trying to rid itself of these outrageously expensive customers.

Put it all together, and this report is on the soft side of mediocre.

Unemployment and underemployment both remain very high, but they’ve been moving in the right direction. After peaking at 10% in October 2009, the unemployment rate has declined by about 2 percentage points. The U-6 measure of underemployment, meanwhile, peaked at 17.2% and now stands at 14.5%:

(The U-6 measures includes the officially unemployed, marginally attached workers, and those who are working part-time but want full-time work.)

Over at the Atlantic, Garett Jones gives one economic explanation for this finding: memories are a durable good.

[M]emory, wholly intangible, is quite durable.

People often shrink from driving to a distant, promising restaurant, flying to a new country, trying a new sport–it’s a hassle, and the experience won’t last that long. That’s the wrong way to look at it. When you go bungee jumping, you’re not buying a brief experience: You’re buying a memory, one that might last even longer than a good pair of blue jeans.

Psych research seems to bear this out: People love looking forward to vacations, they don’t like the vacation that much while they’re on it, and then they love the memories. Most of the joy–the utility in econospeak–happens when you’re not having the experience. …

[P]eople treat memories somewhat like durables, but most of us could do a better job of it. Yes, it’ll be a hassle to find that riad in Marrakech when your GPS fails you, but complaining about it with your sibling years later will be a ton of fun. Get on with it.

A corollary: if memory really is a durable, then you should buy a lot of it when you’re young. That’ll give you more years to enjoy your purchase.

So it’s worth a bit of suffering to create some good memories, since the future lasts a lot longer than the present.

That’s good advice. But I can’t help thinking that people who are unhappy on vacation are doing it wrong. Then again, maybe my recollection is blurred by selective memory?

In any case, the little feline above is a great example of Garett’s thesis. Since I was a child, I had always wanted to see an ocelot in the wild. And last summer, Esther and I found one in Brazil. Our entire encounter lasted about 15 seconds and produced a couple of mediocre photos. But until my brain gives out, I will always cherish seeing the little critter.

P.S. About 20 years ago, I recall someone attributing the “memory is a durable good” idea to Milton Friedman. If anyone’s got a cite to that, please post in the comments.

P.P.S. Will Wilkinson also comments on Garett’s thesis.

If you have time for more, here’s another famous episode, with a very different display of strategy and tactics:

P.S. In case you missed it, here’s Jon and Courtney’s overview of the entire federal budget. They also have nice graphics on discretionary spending and federal revenues.

P.S. Most TV interviews involve starting into a camera and listening to a voice in your ear. So this was a fun change with Alice, Jeff, and me together.

Your ATNOL for a loss year is the excess of the deductions allowed for figuring the AMTI (excluding the ATNOLD) over the income included in the AMTI. Figure this excess with the modifications in section 172(d), taking into account your AMT adjustments and preferences (that is, the section 172(d) modifications must be separately figured for the ATNOL).

So who is to blame? Feckless politicians? High-priced lobbyists? Social engineers?

Well, yes, yes, and yes. But Howard looks deeper and asks why Americans don’t rise up against the scourge of needless complexity. Why are we so complacent?

His answer: TurboTax. By buffering us from complexity, tax preparation software allows that complexity to persist:

[T]echnology both inoculates us from much of the complexity of tax filing and reduces compliance costs. But, more importantly, it immunizes the politicians from the consequences of their decisions that lead to this madness.

Taking this to its logical extreme, Howard calls (tongue-in-cheek) for a one year moratorium on tax preparation software and, for good measure, paid preparers too.

I’m not ready to go that far. But I would like to point out that the dynamic Howard points out is everywhere around us. Give people cellphones that make it easier to call for help, and they will get into more trouble in the wilderness. Offer people low-fat cookies, and they will eat more. Put people in more fuel-efficient cars, and they will drive more. Give people software to do their taxes, and they will accept greater complexity. It’s practically a law of nature.

P.S. Over at Republic Report, Matt Stoller levels a more serious charge at Intuit, the producer of TurboTax. Quoting from its SEC filings and lobbying data from Open Secrets, he argues that the company has been lobbying against efforts to make it easier for citizens to file without the help of software.
