Tax policy colloquium on "Long-Term Objectives for Government Debt"
Whew, this is going to be a tough one, I thought, when I saw the first page, which starts: "Finanspolitiska radet are en myndighet som har till uppgift att gora ... " etc. Okay, just kidding there. That actually is the first bit after the title page, but it comes from the soon-to-be-published book's credits, and it's the only part that's written in Swedish rather than English.
Alan identifies the three main issues associated with budget deficits and public debt as generational equity, economic efficiency or performance, and fiscal sustainability, which he identifies with a possibility of a fiscal disaster such as default or hyper-inflation. (The fourth big issue is its political economy effects, mainly reflecting political incentives to (a) defer and/or under-specify financing for government outlays and (b) pre-commit future governments' budgets because they may not share one's currently ascendant priorities. I quibbled a bit about Alan's list, notwithstanding that I have used exactly the same list in some of my writing. (Consistency being the hobgoblin of petty minds, after all.)
On generational equity, Mihir Desai argued, and I tend these days to agree, that, while the issue is important and while better information about government policy is surely welcome, it is hard to say how the policy we are actually following compares to the optimal policy. We know so little about future generations' circumstances relative to our own, and about the actual marginal costs and benefits of shifting consumption opportunities one way or the other. Sustainability, not generational equity, is actually the big enchilada so far as telling us that U.S. fiscal policy is on a dangerously bad path is concerned.
On economic efficiency or performance, I did the quibbling. As I define this category, there isn't a lot of efficiency at issue in the standard microeconomic sense. There are stabilization / counter-cyclical fiscal policy issues, though unfortunately deficits provide a poor measure given that the composition of tax and spending changes is so important (e.g., transfers to people with high versus low propensity to consume, rewarding existing investment versus new investment). And there are issues of effects on national saving, although again here composition is important and the main complaint, if fiscal policy reduces national saving, is a positive externalities story about saving.
Alan also puts in category 2 issues of tax smoothing, or having more constant tax rates over time rather than having to raise them suddenly because one has finally woken up to the sustainability problem if taxes aren't adequate over the long run given spending levels. At the risk of being a nitpicker, however, I put this in category 3, sustainability issues.
Alan views the sustainability issues discontinuously, in terms of the very real risk of a big meltdown or credit event along the lines of a run in the bank. I agree that this is the really big and growing risk or concern about our unsustainable fiscal policy - explicit or implicit default, hyper-inflation, collapse of the banking system, and so forth. As I say in Taxes, Spending, and the U.S. Government's March Toward Bankruptcy, this actually might happen, and indeed it verges on certainty of happening IF the U.S. political system can't function adequately. (It usually has in the past, but the last seven years make one a bit less optimistic.) But I would include in this category, because they are merely lesser versions of the same problem and have the same cause, lesser versions of the harm caused by deferring any serious response to sustainability problems. Examples include:
(a) foregone tax smoothing, leading to unduly high and distortionary taxes or tax rates in the future because we didn't raise them more moderately sooner,
(b) foregone consumption smoothing, such as from steep Medicare cuts in the future that cut more into essentials because more moderate cuts, hitting less vital and valuable services, weren't imposed sooner, and
(c) tough times for future elderly people whose benefits are cut late in the game, when they can no longer react by saving more, leading to their own accentuated failures of lifetime consumption smoothing.
Anodyne though it may sound, this can actually involve really bad stuff that was completely avoidable. And again, we basically agree about all of this - more of a semantic debate regarding how to conceptualize it.
We also struggled with tough questions of fiscal measurement that lack good answers and probably always will. The fiscal gap - say $80 trillion or about 10 percent of the present value of all expected future GDP (these numbers are made-up, but probably within the realm of a reasonable estimate) - sounds alarming, but strictly speaking is just a statement about statements; that is, a measure of the degree to which a reasonable projection of the current policy path actually is impossible and will not happen. Mere words don't automatically hurt, however. Thus, in thinking about the problems (such as fiscal meltdown risk) implied by the fiscal gap, we need to think about softer variables such as degrees of pre-commitment or lost flexibility.
For example: Joe Stiglitz projects an Iraq war cost of $2 or 3 trillion. Medicare prescription drugs has an infinite horizon revenue cost of more than $20 trillion. But these two numbers aren't entirely comparable, because the Iraq costs are largely water under the bridge - little we can do about them now - whereas we could actually back off spending all that money on future Medicare prescription drugs. This is a point about irreversibility, not about present value or risk / variance. Alan's article introduces a couple of concepts such as "implicit liabilities" and "deferred tax assets" that attempt to advance thinking about these issues - which I agree they do, although this post is already too long for full further discussion to make sense here - but in dealing with soft variables through the medium of a fiscal measure we will never be entirely satisfied. And, how we think about something such as the Medicare prescription drugs dollars (assuming one agrees about the remaining flexibility) does in part depend on whether one is thinking more about fiscal meltdown issues or broader smoothing / optimization issues.

Ray Davies concert
How au courant to be going to such a concert, some of my NYU colleagues said. Not that I was trying to be. Better just to rest after a day of long hard slogging, if that were the goal. But another colleague, who actually is somewhat au courant, used instead the word "old-fogeyish" to describe going to such a thing. (Had he seen the audience in the orchestra section of the theater he would have felt entirely vindicated.) But my true reason for going was that I hoped the concert would be interesting and fun. It was - and I felt really revived afterwards.
The biggest surprise, though I suppose it shouldn't have been, was what a showman, as well as a hungry sponge for audience acclaim and approval, Davies proved to be. Also seemingly a genuinely nice man, although that isn't the standard formula for a rock 'n' roll lead singer (and on-stage appearances can surely be deceiving). There's so much depression, scorn, and paranoia in some parts of his songwriting canon that I was expecting something a bit different. (Maybe I was succumbing as well to the romantic myth of the lonely, suffering artist.) Obviously lots of other parts of his canon express something very different than this (e.g., Days and Waterloo Sunset). But one could see how integral to his overall set of drives were his fifteen plus years (from the early 70s on) of playing dreadful arena rock so as to "give the people what they want" (as one of his album titles put it).
So there he was, actively seeking sing-alongs on all the old Kinks hits, coming back on stage when the show seemed to be over because he wanted to do just one more number, then doing another one after that, thanking the crowd, mourning the Kinks, throwing repeated verbal bouquets to the guitar playing of his estranged brother Dave, praising his current band and asking if we liked them too, etcetera.
More needy than smarmy, however. And he's still a great singer as well as one of the premier rock songwriters, with his trademark plaintive but indelible minor-key hooks that only the Beatles could really do as well. (That plus the articulate lyrics, ability to capture moods, and the memorable power-chord runs that others such as the Who stole from him.) No other songwriter from that era has come close to his recent writing except for Dylan, who still sets his own standard but really just on Modern Times.
Almost all Kinks in the first set (although two from his first solo release), then after the intermission five or so cuts from the new album starting out acoustic then returning to the full band, and finally a mix of old classics with more new stuff. Almost all of his Kinks material was from the band's first 3 or so years. Nothing from Village Green unless you count Days (which is from the same era and is on the extended reissue but not the original album). Only 3 songs from the 70s and 80s, which (Lola excepted) was a mercy. And the new material really did stand up to the old although perhaps not quite as rousing.

NYU Tax Policy Colloquium on "Making Social Security Work"
The chapter describes the Social Security fiscal crisis - which some people call large, others small, even when they agree about its actual size (a bit like arguing about whether a spill on the floor is big or small - what the heck, either way at some point we'll have to wipe it up). It offers this as motivation for fixing the system to have a level-one demogrant for seniors plus a level-two individual account, in lieu of the current benefit structure.
As Mihir Desai noted in the discussion, one could fix the Social Security fiscal gap without fundamentally changing the structure. (A bit later retirement, a bit higher payroll tax rate or ceiling, a bit slower benefit growth relative to wage levels, etc.) Or, one could change the fundamental structure, if one likes a different one better, even in the absence of any long-term fiscal problem.
More quibbling: In terms of the book's idea of rewarding, or at least not overly penalizing, work, penalizing it is basically what the fiscal system does in light of its basic distributional aim of treating Bill Gates as better-off as the readers of this blog, and them in turn as generally better off than homeless individuals. A consumption tax burdens work, as does an income tax or any other plausible base. Sure, there are some silly Social Security features that needlessly discourage work, such as the treatment of earnings by people age 62 to 66 if they have selected early retirement, or arguably the lack of a clearer tax-benefit link in the system (so that the marginal burden it imposes on work arguably seems higher than it actually is). Fundamentally, however, discouraging work up to a point is the name of the game. Why select it as a key consideration here?
Somehow, the conversation ended up devolving into the good old income tax versus consumption tax chestnut that has occupied us so often in past years' sessions (though for this year, it was a first). Forman argued that using general revenues (and thus the income tax) is more efficient than payroll tax financing because it covers a larger percentage of GDP. But, insofar as that reflects the difference between an income and a consumption tax base, one must keep in mind the tax policy and economics literature's recent finding that an income tax is likely to be less efficient because its burdening savings on top of work does not mean that it burdens work any less. Just because GDP happens to be an income measure doesn't mean we should think about efficiency in terms of the percentage of GDP covered. It's true that the income tax also reaches wages in the economist's sense that are not legally wages for payroll tax purposes. But then again it is also true that the existing income tax base has more preferences built into it than the payroll tax base (they share the preferences for fringe benefits and such, but the income tax has lots more such as home mortgage interest et al). So anyway, why should we think that income tax financing would be better? (Rate structure is a separate point.)
Anyway, just speaking for myself, I didn't think I came out of the day knowing all that much more than I had going in. But it was a lively and interesting session.

Forthcoming testimony
Tuesday, April 01, 2008
Yes, it's April Fool's Day, and no, I wasn't born yesterday
"Dear Professor Shaviro:
"We represent a very small but very wealthy nation that has asked us to approach you. This nation is about to launch a revolutionary effort to adopt some of the values of countries that have been developed economic powers throughout recent history. In particular, this nation’s ruling family is interested in a modern and explicitly progressive system of taxation.
"The ruling family is acquainted, in some cases directly, with your thinking. We (my organization is resolutely obscure, but we did great deal of research to identify you) and they have identified three candidates in total to approach: you and one other from the United States, and one from Norway.
"While the intellectual challenge of designing a system of taxation from scratch would be of the highest order, the compensation alone would be enticing. For your time in consultation amounting to let us say some 500 hours, perhaps concentrated in the summer, something in the very high six figures seems appropriate, with the possibility of a continuing relationship.
"To date, revenue from this nation's resources has made progressive taxation unnecessary, and that state of affairs continues. The family’s motivation is not to find more funding, but rather to embark on a approach that embodies concepts of economic justice that we believe you understand and can apply.
"If this opportunity interests you in any way, we would appreciate the chance to meet with you in person. You should be advised that the ruling family, while moving toward Western values in many ways, appreciates what they consider a dignified appearance: coat and tie (or burnoose), highly polished shoes or boots, carefully combed hair, and so on.
"We look forward to hearing from you."
[Followed by organization name, Wall Street address, and 800 number.]
Okay, let's get this straight. On April Fool's Day, someone simply cold-e-mails me to offer close to a million dollars for doing what all academics ostensibly dream of - getting to play philosopher king. I guess I'd better get my burnoose cleaned and pressed.
What I actually did, just out of curiosity, was (a) google the supposed organization and draw a blank, and (b) have my secretary call the 800 number, which turned out to be a porno line.
At least they didn't ask me for $10,000 or my private security codes. But I guess that million-dollar payday for getting to play philosopher king will just have to wait.
New publication
On second thought, if you press the link you'll see that Amazon lists it as coming out later this month.
As it is a bit pricey, anyone interested just in my chapter should e-mail me off-line.

NYU Tax Policy Colloquium on "How Americans Think About Taxes"
My version of Amy Winehouse
Thursday, March 27, 2008
Doing their homework
As it happens, I haven't posted on any other candidate's tax plans other than ol' Fred Thompson (you know, the actor) along with some snark concerning this now-forgotten guy who used to be a big shot, I think named Rudy Guiliano or Guilianus or something like that (it's hard to remember these days).
I've been thus scattershot about the candidates' tax plans because I find it hard to really take an interest in these things until I have reason to believe that the candidate is actually going to (a) win and (b) propose his or her plan. Plus, I sometimes have an aversion to overly low-hanging fruit, which is what criticizing a candidate's tax plan can amount to given all the political constraints on proposing sensible tax policies. So in a way it was a compliment, albeit less to Obama himself than to his economic advisor Austan Goolsbee, that I considered the plan worth criticizing.
Anyway, someone's campaign must be reading these things given the apparent genesis of the invitation. Good to know I'm not all alone out here.

Work, publication, and reading update
OK, I'll fess up to the one other bit of work I did, which was to plan (at a basic conceptual level) my remarks at the NYU Tax Policy Colloquium this Thursday, where we will discuss "How Americans Think About Taxes: Public Opinion and the American Fiscal State," a forthcoming (Princeton University Press) book excerpt by Andrea Louise Campbell of MIT's Political Science Department. I like the excerpt, which discusses why tax politics has moved recently in a less progressive direction despite the arguable financial self-interest to the contrary of non-rich American voters. Campbell uses, among other inputs, detailed polling data over several decades and a sophisticated theory of perceived cost-benefit from tax rules. Naturally, given my work and interests, this is a topic on which I have plenty of my own ideas. I anticipate a fruitful discussion.
I also found the time to read 4 books. (Reading fast is a bloody nightmare when it comes to packing for a vacation trip - you end up with plenty of bulk and still have to worry about running out.) First was "Zhou En-Lai: The Last Perfect Revolutionary." This perhaps unlikely bit of beach reading is a book written by a Chinese exile and U.S. emigre who for years had access to top secret Chinese Communist Party files from the 1960s and 1970s. After a slow start it became fascinating and even genuinely moving, showing how Zhou worked with the utterly mad and monstrous Mao, trying above all to survive and also to moderate him but also enabling him. The book reaches the conclusion that Zhou tried to be a decent person but failed because of the demands the system placed on him plus his own human failings such as the need to subordinate himself and comply. Extra points for satisfying the curiosity of one who grew up reading the crazy news from China in the Cultural Revolution era without having any information (which no one in the West had) about what was really going on behind the scenes. E.g., what was the deal with Mao's "closest comrade in arms," Lin Biao? Now I know, and it's a much more interesting story than I had expected.
Second book was "Smile When You're Lying: Confessions of a Rogue Travel Writer" by Chuck Thompson, an at times uproarious collection of travel experiences packaged as an expose of all the fakery and hype in the travel industry. Good not so clean fun.
Third was "Mayflower," by Nathaniel Philbrick, a history of the Plymouth Bay and related settlements from founding through the horrific Indian wars of the 1670s. Guess who were clearly the bad guys. A good read but not in my view great.
Back from vacation
One of the Iberostar's best features is the wildlife living on the property - howler monkeys that I got to see daily after stumbling on their PM hangout site in the canopy, big iguanas, peculiar rodents that might be capybaras, and some beautiful though exceptionally pompous peacocks that were strutting around the pathways and in one case decided to challenge me. (I held my ground, figuring that I weigh more.) Best activity was letting waves wash me onto a surfbreaking structure resembling rock but actually a canvas filled with sand. Very slippery in spots where algae had grown onto it.

In the picture here I'm in the background, having ridden a wave onto the structure but not having yet been washed off. (This apparently was the day I decided not to stand up any more before the waves got me - there's only so much pounding you can take at age 50 plus.)
Second picture is one of the local beastie residents whose favorite AM sunning site we discovered. You can see that he or she is sitting on top of another iguana's tail.

Today (Sunday), things are not quite so idyllic. I'm in my office reading literally hundreds of pages for work (appointments committee, etc.) that I decided not to trouble myself with while in Mexico. Or rather, I am finding a way not to read them at the moment.

Tax policy colloquium on EC tax policy
Ruth proposes a Kantian-sounding (but not actually Kantian) diagnostic for tax discrimination, which the European Court of Justice (ECJ) has a mission to strike down while permitting mere "disparity." She would have the ECJ ask whether cross-border activity or those engaging in it would be disadvantaged if the tax law of the jurisdiction that is being challenged were universalized, i.e., adopted to the last comma by all other jurisdictions. It's a proposed diagnostic rather than a proposed standard, because one could analogize it to the skin test for tuberculosis - the question is whether one actually has tuberculosis, not whether one's skin swells where they inject you, but if it doesn't swell then you're home free whereas if it does you face further tests.
The key problem here is that, while we have an objective standard for tuberculosis (once all the facts are known, one unmistakably either has it or doesn't), the same cannot as easily be said for tax discrimination. What is it? Mihir Desai, my co-convenor for the last seven weeks of the colloquium, and I felt that one really needs to define it, at least conceptually, in order to have any sense of what one is trying to do, but lawyers who have spent less time with economists than I have often scoff at this and say no worries, we can proceed anyway. Definition, we don't need no stinkin' definition.
Mihir proposed an idea that Michael Graetz and Al Warren have also written about, to the effect that discrimination might be found if one violates either capital import neutrality (equal treatment of one's outbound investments with those in the source jurisdiction) or capital export neutrality (equal treatment of home and outbound investment). The punchline Michael and Al derive from this, and which Mihir suggested as well, is that tax discrimination, if defined this way, is a hopelessly incoherent concept. All taxes, home and abroad, would need to be harmonized if one wanted to fully satisfy both CIN and CEN, and this is not among the options on the table. The Europeans in the room loudly hooted at this interpretation of what they and the ECJ have in mind by tax discrimination - as I gather they also did in the past, on multiple occasions, when Graetz and Warren proposed this view.
Luckily for me (since I have to make some comments later today at the EC Tax Policy conference here), I felt that the session eventually helped me to understand what they appear to have in mind when they discuss tax discrimination. Very roughly speaking, and falling short of an operational definition, I'd say the idea is (a) negative cross-border tax synergies, or higher total taxes from being in two jurisdictions than one would have had from the sum of being separately in each, that (b) are not considered justifiable all things considered (e.g., considering how bad the impact is, how deliberate it seems to be, how easily the government could have avoided it without being forced to change rules that it might like for "innocent" reasons, etc.).
Not very crisp, and I don't have the time pre-vacation to try to spell it out more, but for me at least this helps conceptually. Seen this way, the idea isn't incoherent, although it is a bit mushy, underspecified, and vague. And not necessarily a bad idea to have courts doing this in an ECJ-type or US national setting.

Musical update
Ray Davies' new album is really good. Probably his best album of new material since Arthur (with the Kinks) back in 1969, although this is not as high praise as it may sound as there are few intervening contenders. The Kinks, after having extraordinary self-direction and integrity in the mid-1960s, when they paid a price for not trying to fit in, spent the next couple of decades being as crassly and reductively commercial as one could possibly be. Plus Ray got too boringly bitter. The current album has a few overly preachy political moments, but overall it's a bit as if Lennon had lived, mellowed, and rediscovered a voice that could work for him.
The new Dengue Fever album is very enjoyable and lively. Not sure if I will want more of their work, but the fusion definitely works.

Intellectual progress at the NYU Tax Policy Colloquium
One question I raised at the PM session is whether outbound investment is necessarily distinctive in this regard, if what we have in the main is a story about economies of scale and rising vertical / horizontal integration in an era when the general worldwide business environment may be transforming itself. E.g., suppose we did the same type of study regarding whether investment in California by a nationwide firm is a substitute or a complement for investing elsewhere in the US, and got the same result.
But the main topic was the U.S. international tax policy implications, about which I am reluctant to say too much because it would make this post too long and anyway I'm planning to write about it this summer. But one thing that became clear is that exempting outbound investment by US firms does not necessarily emerge as the logical consequence of the paper's findings, and that when Desai, Jim Hines, and others describe exemption or national ownership neutrality (NON) as an efficiency benchmark, they don't mean a tax policy benchmark. To give a sense of the difference, a lump sum tax such as a uniform head tax is in some settings an efficiency benchmark, but not a reasonable proposed policy. In that setting, the complicating issue is concerns of distribution as well as efficiency. In the international setting, the complicating issue is that one is choosing between inefficient tax instruments and attempting to minimize overall inefficiency.
I call this post "Intellectual progress at the NYU Tax Policy Colloquium" not because of that point in particular, but because it was one of those sessions - meeting our ideal, which one can't always do - at which the group dynamics and interplay resulted in advancing the thinking of lots of participants about these issues. It was a collective exercise and perhaps will show up in the future writings of several of us.

My letter to the editor of Tax Notes
[A]t least one of [Warren's] key conclusions, dismissing the BEIT plan as having no apparent rationale, is overly harsh in an important way. I therefore wish to augment the debate by explaining why, in my view, the BEIT remains an important corporate tax reform proposal that merits further attention notwithstanding any defects in its current form that he may have demonstrated.
I should note, however, that in two respects my analysis here is orthogonal, rather than directly responsive, to
Second, one reason I consider the BEIT potentially appealing relates to a possible direction of U.S. tax law change that neither Kleinbard nor Warren considers because it has not happened yet, and indeed may never happen. Purely as a matter of prediction, and without regard to the policy merits (though they might be positive), I believe there is a strong chance that worldwide competitive pressures will lead the United States to adopt a corporate tax rate that is significantly below the top individual rate .... [This] would give new importance to the way in which the BEIT relates entity level and investor level tax collection.
Only one previously proposed corporate integration plan resembles the BEIT in its approach to the income tax distinction between debt and equity: the comprehensive business income tax (CBIT) that the U.S. Treasury Department proposed in 1992. In effect, the CBIT would revise the tax treatment of debt to be more like that of equity, by denying deductions for interest at the business level and making the receipt of both interest and dividends generally tax-free to investors. The BEIT reverses this, making the tax treatment of equity more like that of debt, by providing cost of capital deductions at the company level along with inclusions at the investor level.
This reconciliation between the tax treatment of debt and equity, accomplished by both the CBIT and the BEIT, could be enormously important. Modern financial innovation has made the tax distinction between the two types of instrument ever more porous and manipulable. Insofar as investors can slap whichever label they prefer on whatever sort of investment position they wish to have, the debt-equity distinction amounts to an election to use either the corporation’s tax rate (via the use of equity) or one’s own (via the use of debt), whichever is lower. It is hard to think of a good rationale for such an election, and allowing it might be all the more significant if the corporate rate were reduced significantly below the top individual rate.
Why reverse the CBIT approach and tax the normal return at the investor rather than the corporate level? This has been my main concern about the BEIT, as the change might not make enough difference to be worth the trouble if the corporate rate and the top individual rate are the same. However, if I am right in my surmise that the corporate rate may soon be lowered significantly below the top individual rate, then at some point it really will matter. What is more, one could argue that the BEIT approach is better in this scenario, if the reason for the lower corporate rate is entity-level capital mobility that does not apply in the same way to high-income individuals who are

In this exchange, the problem is that we are talking past each other a bit. I am more interested in the pure analytics, they in what is likely to be one's practical bottom-line conclusion. I don't think they really disagree with me about the analytics, only they seem to me a little less interested in looking there as a pure intellectual exercise. And I don't disagree with them about the likely bottom line conclusion in favor of a consumption tax.
Was I just nitpicking? I don't think so. It's important to have a really clean grasp of the analytics before proceeding with real world conclusions, which one should do as well but with all due intellectual reticence given the gap between simplified economic models and real world implementations.
