Short comment paper published, responding to Gabriel Zucman's global billionaire minimum tax proposal

Intertax has just published and posted a new article of mine responding to Gabriel Zucman's global billionaire minimum tax proposal. Available here. Title and citation: Belling the Cat? A Response to Gabriel Zucman’s Billionaire Minimum Tax Proposal, 54 Intertax 24-32 (2026). 

The abstract goes something like this: Gabriel Zucman’s global billionaire minimum tax proposal has significant merit in the realm of ideas to place in the progressive tax policy tool chest. While, if I were the global tax policy czar, I might change it in various ways, I would nonetheless support its adoption as is, relative to the alternative of simply doing nothing about the rise of extreme high-end inequality. If, in the end, it fails to offer a politically promising path forward, as I fear that it does, the fault lies not with its proponent, but with the political realities of our troubled times.

Paper influenced by Alan Auerbach

The following is the text of some brief remarks that I offered at a conference in Berkeley last Friday honoring Alan Auerbach upon his retirement. Guidelines for these remarks suggested that one discuss recent work of one's own that reflected Alan's influence and intellectual presence in any of his multiple fields.


My most recent, though hardly my only, Alan-influenced, piece is called Time Is, Time Was: Evaluating the Use of the Life Cycle Model as a Fiscal Policy Tool, which recently appeared in an Elgar Research Volume on Law & Time. It responds to Alan’s important recent work with Larry Kotlikoff & Darryl Koehler, using intra-generational accounting to measure US economic inequality & fiscal progressivity.

Alan’s work with Larry and Koehler (which I’ll call AKK to save time) does this by using lifetime spending power, in lieu of such snapshot measures as income or wealth. It finds less economic inequality, and more progressivity, than you’d find using the snapshot metrics. I would guess that not all members of the Berkeley Economics faculty, even limiting it to those in this room, agree 100% with the paper’s analysis. But the analysis would simply be right, leaving nothing further to discuss, if one fully granted the premises that, over the full lifecycle, people exercise consistent rational choice, in the presence of complete markets, leaving aside liquidity constraints.

In a standard analysis of consumer choice between, say, movies and pizza, people seek to equalize the marginal utility of the last unit they consume of each commodity. AKK applies the same approach to consumption in different periods, on the view – surely correct – that these are in effect separate “commodities,” each subject to its own declining marginal utility as one consumes more of them. But my piece argues that equalizing marginal utility across periods is considerably more challenging than doing so for movies and pizza, and also is subject to various heuristics & decisional metrics that would be irrational in the absence of real world decision costs. Plus, changes in information that aren’t fully insurable may have an impact.

I conclude that the underlying model, under which it basically doesn’t matter when one earns a dollar, in determining when one spends it, is not sufficiently descriptively accurate to be treated as more than an important orienting benchmark. Like such other “it doesn’t matter” theories as the Coase Theorem, the Efficient Markets Hypothesis, and the Modigliani-Miller Theorem, its value lies more in its showing us where to look for falsifying conditions, than in its full empirical validity.

Does this mean that we should keep on using traditional snapshot metrics such as income and consumption after all? Not at all. They still have all the flaws that AKK rightly attribute to them.

I conclude that there is no simple answer to the question of how lifetime, as opposed to shorter periods (themselves requiring further definition) should be used in measuring economic inequality, fiscal progressivity, or the question of why (and how much) inequality matters. Indeed, perhaps more important than any particular conclusion is the need for continuing methodological humility and agnosticism in how we think about these issues.

Forthcoming publications

I have three new articles coming out shortly. The first, in Tax Notes International next Monday (but already available behind a paywall online) is “Digital Services Taxes vs. Pillar 1: Did the U.S. Catch a Break and Not Even Notice?”

The second, forthcoming in the Virginia Tax Review, is “Right Taxpayers, Wrong Taxpayers, Deduction-Selling, and Proxy Taxation.”

The third, forthcoming in a symposium issue of the Loyola of Los Angeles Law Review, is “Couples Neutrality, Marriage Neutrality, and Two-Earner Deductions.”

I haven't put any of them on SSRN as yet, but will do so shortly.

New articles, current and near-future

I had a sabbatical this past spring, and thus haven't been in a classroom since the end of fall 2024. One way I've used the time is in writing.

Leaving aside my memoir (available at https://www.amazon.com/Now-Then-Memoir/dp/B0FD424K9C/ref=sr_1_1?crid=2Z45SW78HPMOI&dib=eyJ2IjoiMSJ9.qDclUhMzvsVrpnD5L2tQq7HGEofxNIvs96-FGLn4dAc._XzxKpdAJk1wDl7ZgmUBu_wZVfq02XFq_YOC_f6Wcao&dib_tag=se&keywords=daniel+shaviro+now+is+now+and+then+is+then&qid=1752697305&sprefix=daniel+shavir%2Caps%2C121&sr=8-1), the first fruits of this activity are now moving towards publication. The Virginia Tax Review will soon be publishing a piece entitled Right Taxpayers, Wrong Taxpayers, Deduction-Selling, and Proxy Taxation. Plus, it is possible that Tax Notes, in the late summer or early fall, will publish a piece that is currently titled Did the United States Catch a Break and Not Even Notice? Assessing the Rise of Digital Services Taxes In Lieu of Pillar 1. Note that, in this article title, the question mark plays a crucial role - I am addressing a possibility, not making a definite assertion. 

Other topics that I've been working on, or will soon, include (1) a kind of mainly twentieth-century intellectual history of debate over the proper uses (or not) of the Haig-Simons income definition, (2) a piece on Social Security that explores the current intellectual and policy relevance of classic works on the subject by Paul Samuelson and Martin Feldstein,* and (3) possibly something about economic concerns that are adjacent to the not very economically (or philosophically) well-grounded notion of international tax nexus.

*I was critical in some respects of Feldstein's Social Security work when it came out, but I suppose that by now it has become "classic." Also, it has virtues as well as defects.

Another five-star Amazon review of my memoir

This one goes as follows: "Pure gold. Easily the most honest memoir I've ever read: bracingly real, sharply funny, and deeply human. Whether or not you're familiar with Dan's immense contributions in law and public policy, this is absolutely worth the read."

I don't know who posted this (since it's first-name only), but a fair inference from reading it would be that we (probably) do know each other.

Review of my memoir on Amazon

 Unexpectedly warm and insightful portrait of the Baby Boom Generation. (5 stars)

Reviewed in the United States on June 29, 2025

Verified Purchase

Who knew that law professors were so funny? This is a warmhearted and introspective series of vignettes that provide an unexpected insight into the life of young professionals from the 1950s to the 1980s. Always entertaining and never boring, even when one might expect it to be. A great read.

Zero revenue cost from any and all tax cuts, forever and ever

I gather that the GOP score of the Senate tax bill DOES show budgetary costs as being lowered by the expiration of new provisions (such as the higher standard deduction) that it would add to the Internal Revenue Code. This blatantly contradicts its use of a "current-policy" baseline for 2017 provisions.


The Senate GOP's refusal to use a current-policy baseline for NEW provisions means that, the day after enactment, they could pass a new law making all of those expiring provisions permanent, and claim a budgetary cost of zero.


But why stop there? From now on, they should simply make ALL new tax breaks that they enact expire in a week. This would create next to zero revenue loss no matter what they were doing. Then, the next day, they could pass a new law making the same provisions permanent, at a zero revenue cost under the current-policy baseline. They could even, under this approach, repeal all U.S. federal taxes, and claim a zero budgetary cost.


Good work, guys.

Quandary

 Over the last few months, I've written a fairly interesting and unique literary work (if I do say so myself). It's a memoir, covering the period from my very first memory through age 29, when I both met my wife and got my first academic teaching job. Tentative title: "Portrait of an Academic as a Young Man."

The distinctive thing about is that it consists entirely of vignettes, which average about 500 words each. There are 114 in all, and the total is just under 58,000 words. I aim at a very rounded self-portrayal - as the cliche goes, warts and all. It focuses broadly on my emotional, social, romantic and intellectual development, culminating in my finding myself, and coming to understand why the path I ultimately chose was right for me. Each vignette places the reader in the room with me, and they generally end with a twist or payoff that brings out the essence of each of the rendered experiences.

The initial feedback that I've gotten from readers is extremely positive. E.g., I have been told that reading it is like having potato chips or chocolate chip cookies on the table – it’s always easy to read just one more vignette, and then the one after that.

Naturally, I would like to publish it. But my initial efforts have been frustrating. The university presses that I've contacted, where they have some idea of who I am, all said that it's not within their scope. And here are a couple of responses from agents to whom I sent it unsolicitedly:

"There is much to enjoy here .... But regardless of my personal feelings, I'm afraid this strikes me as a challenging project for which to find a publisher, your interesting insights notwithstanding. Afraid I'm going to pass here."

And: "You have an interesting idea for a book and there’s a lot to like about your approach. But, in the end, I’m afraid I [won't be able to interest a publisher.]"

I totally understand. These folks are trying to make a living by successfully placing books that will make money. And I suppose it's naive of me to think that literary merit and high readability wouldn't count for more. But still, it's disappointing re. the current state of the publishing world (not to mention, for the book's prospects).

Fingers crossed, as there are still other agents and book publishers to whom I've sent it. But I'm not enormously optimistic. My fallback plan is to self-publish it on Amazon Kindle, a free service that would offer it electronically (at a price of my choosing) andl as a print-on-demand physical book.

I'd love to hear from anyone who is interested in the manuscript or has any thoughts to offer about the project.

2024 NYU Tax Policy Colloquium

With the start of NYU's fall 2024 semester, I thought I should offer an update here on the public sessions at our 2024 Tax Policy Colloquium.

All sessions will meet on Tuesdays, from 4:15 to 6:15 pm, in Furman 310, and most or all will be followed with small group dinners that generally include the speakers.

Here is our schedule:

1) Tuesday, September 10 – Ellora Derenoncourt, Princeton University Economics Department. Wealth of Two Nations: The US Racial Wealth Gap, 1860-2020.

2) Tuesday, September 24 – Andrew Hayashi, University of Virginia Law School. The Federal Architecture of Income Inequality.

3) Tuesday, October 8 – Manasi Deshpande, University of Chicago Economics Department. The (Lack of) Anticipatory Effects of the Social Safety Net on Human Capital Investment.

4) Tuesday, October 22 – Louis Kaplow, Harvard Law School. Optimal Income Taxation and Charitable Giving.

5) Tuesday, November 12 – Alex Zhang, Emory University School of Law. Fiscal Citizenship and Taxpayer Privacy.

6) Tuesday, November 26 – Natasha Sarin, Yale Law School. Broken Budgeting.

An exciting change for this year, compared to the last couple of years, is that the sessions will be on Zoom, and Zoom attendees will be able to participate live. The key change here is that New York State has changed its rules for live class attendance such that a class isn't disqualified as live instruction just because a remote participant asks a question.

I had stopped putting the sessions on Zoom, because that rule made the whole thing just too crazy and hard to manage. Under the prior regime, all that Zoom attendees could do was post a comment that I would then have to read for them. That I found just too difficult while also running a live queue, but I can certainly handle combining my live queue with Zoom attendees raising their hands to ask questions.

Chat GPT's progress over the last year and a half

About 18 months ago (I remember the time because I was visiting at U Va Law School), I briefly got interested in how Chat GPT makes things up. E.g., I asked it what my novel Getting It is about. It confabulated in response that it's about the need for broad-based tax reform, etcetera. (Which, needless to say, it is not - the program generalized from superficial knowledge of my other work.)

Since I gather that Chat GPT improves exponentially over time, I decided just now to give it another try. Here is what I got regarding Getting It:

"Getting It" by Daniel Shaviro is a satirical novel that delves into the life of a Wall Street tax lawyer named Bill Doberman. The story explores themes of ambition, greed, and the pursuit of success in a corporate world where ethics often take a backseat to self-interest.

"Bill Doberman is the novel’s protagonist, a middle-aged lawyer working for a prestigious Manhattan law firm. Despite his outward success, Bill is deeply dissatisfied with his life. He feels stuck in a career that he once thought would bring him fulfillment, but instead, he finds it hollow and unfulfilling. The novel follows his journey as he navigates the cutthroat world of corporate law, where manipulation and deceit are commonplace, and personal and professional lives intertwine in complex and often damaging ways.

"As Bill struggles with his own moral compass, he becomes increasingly aware of the compromises he has made to "get it"—success, wealth, and status. The novel critiques the American Dream by portraying how its pursuit can lead to moral and personal decay.

"Shaviro uses sharp wit and dark humor to portray the absurdity of the corporate world, making "Getting It" not only a commentary on the legal profession but also a broader critique of contemporary society's values."

[Back to me] Okay, this comes closer than before. But a few quibbles: (a) Doberman is a DC, not a Wall Street lawyer, (b) he is not a tax lawyer, (c) he is young not middle-aged, and (d) he does not become dissatisfied with the cutthroat world he inhabits. That may come later, the ending hints, but only due to the limited nature of what he has won. And related to this last point, hopefully it's less cliched in the actual novel to have us, but not him, understand how hollow and unfulfilling his "triumphs" are.

So evidently Chat GPT is still fantasizing and filling in the gaps, but it's coming closer than it did before.

Good news and bad news from the Supreme Court's Moore decision

Today the Supreme Court released its decision in Moore v. United States, upholding the 2017 tax act's mandatory repatriation tax (MRT) on foreign source income (FSI) of American-controlled foreign corporations. The MRT was eminently sensible in principle, although far from perfectly designed in practice, in that the applicable FSI had previously been subject to deferral - i.e., it would be taxed to the US shareholders upon repatriation. Cashing out the deferred tax when you eliminate it, even if at a reduced rate, is very difficult to argue against on policy grounds.

Right-wing activists nonetheless challenged the MRT here on the grounds that (a) the income was unrealized by the taxpayer, and (b) per the long-discredited 1920 Supreme Court case of Eisner v. Macomber, realization is constitutionally mandated for a tax on income to fall within the protective scope of the 16th Amendment.

While the Supreme Court may initially have granted certiorari in response to right-wing fulmination about shutting down the constitutionality of unapportioned wealth taxes and extension of the federal income tax to unrealized gains on publicly traded assets before such taxes were even close to adoption, it soon became clear that the case was a potential nuclear weapon wiping out trillions of dollars of revenue - e.g, from original issue discount (OID) bonds or the flow-through taxation of partnerships. And this was a nuclear weapon that even the likes of Paul Ryan thought it would be insane to set off.

The taxpayers' advocates sufficiently sniffed the air around them to realize that they could only win the case (if at all) by making very limited claims that targeted the MRT in particular while distinguishing it from taxing partnerships, using subpart F to tax US corporations on their controlled foreign affiliates' (mainly passive) income, etc. While this sufficiently limited their theory's "blast radius" (as the majority opinion puts it) to keep its adoption by the court from being immediately catastrophic, it also fatally surrendered coherence and credibility. The provisions that the taxpayers agreed were constitutional simply could not be distinguished from the MRT.

Good news: the Supreme Court upheld the MRT in a quite sensibly written opinion by Justice Kavanaugh. The vote was 7-2. What the opinion does is say that the MRT is not about realization at all: the income being taxed unambiguously has been recognized at the entity level. So the case is merely about apportionment, not realization. The opinion notes longstanding precedents that permit an entity's income to be taxed either at the entity level or directly to the owners. And, given the basis for decision, it holds that issues about taxing unrealized income simply aren't reached here.

Bad news: the Supreme Court has at least 4 votes (and possibly as many as 6) in support of the proposition that Eisner v. Macomber's idiotic and long-renounced "realization / severance" requirement for treating economic income as taxable income is indeed binding constitutional law. Justice Thomas, joined by Justice Gorsuch, offers his usual brand of dishonestly cooked "history" in support of the taxpayer in Moore on realization grounds. Meanwhile, Justice Barrett, joined by Justice Alito, concurs only in the judgment, and only on the ground that the taxpayers' concessions in distinguishing the MRT made their position unsustainable.

Will the Court soon hold that it is unconstitutional to tax income from OID bonds, on the ground that it hasn't been realized? Or if not income from OID bonds, then at least the unrealized gains of very wealthy individuals, as per a bill recently introduced by Senate Finance Chair Wyden? There may well be 4 votes for striking down one or both of such provisions.

Kavanaugh's opinion expressly declines to reach that question, rightly noting that it's unnecessary to decide Moore. One can reasonably presume that both he and Chief Justice Roberts are potential 5th and 6th votes for holding that realization is constitutionally required. Meanwhile, only Justice Jackson, in a concurring opinion that no other justice joined, stated forthrightly that there is no realization requirement in the 16th Amendment.

So let us express relief about the present, along with continued concern about the future.

Henry Simons and pre-World War libertarianism.

 I just posted this piece on a libertarian-affiliated U of Chicago website. Based on a 2013 article that I wrote concerning Henry Simons. It discusses the question of why a Friedrich Hayek-affiliated "classical liberal" would have supported both vigorous anti-monopoly enforcement and a high-rate progressive income tax - positions that are anathema to the likes of (say) a Richard Epstein or Milton Friedman (if he were still alive) today.

Two pop songwriters

It occurred to me recently that my two favorite pop songwriters of the last 25 years - Fiona Apple and Stephin Merritt (The Magnetic Fields) - on the surface seemingly couldn't be more different. So why should they both be personal favorites of mine? True, both are astonishingly gifted, but there are other talented songwriters out there as well.

Part of it is just happenstance and stylistic affinity. And I have nowhere close to as broad a sense of what's going on in the music biz, even limiting it to the relatively rock-affiliated space, as that which I had, well, let's just say some decades ago. Nor am I (admittedly) as open to new things as I was once upon a time, and these are both among the sorts of artists who get (well-deserved) rave reviews on the apparently-soon-to-be-defunct pitchfork.com.

But then it occurred to me that there is actually an odd commonality to them, which consists in part of their responding in almost opposite ways to the same underlying problem.

Both were born in the rock era (Merritt 1965, Apple 1977), and were very influenced by it. But both are also much more broadly and eclectically grounded in popular music, including that from the pre-rock era (e.g., show tunes). But the problem to which I see them alike responding is that of writing great popular music after so many decades in which this territory has been so thoroughly covered. After the Beatles, Dylan, Carole King, Motown, Brian Wilson, Patsy Cline, Lou Reed, Ray Davies, and so much more for so long, I would think that it's hard to avoid feeling a bit self-conscious, as well as derivative of one thing or another, when one is trying to write songs in this space.

Fiona Apple's response is to be so raw, unfiltered, and utterly un-self-protective as to blow past the models she surely has. Try writing a memoir in the spirit that she writes her songs (at least, pre-Fetch the Bolt Cutters). It would be verging on impossible to make oneself do it, even if one had felt things as deeply as she evidently has. Now, there's no lack of very conscious and careful artistic shaping of what she does - for example, beautiful melodies, nice piano riffs, odd and shifting time signatures, what the Beatles liked to call "middle eights," carefully arranged intros and outros, loud-soft-loud and rough-sweet alterations, extended metaphors, and big vocabulary words. But she lays herself out there in a way that very songwriters or performers can.

I admittedly haven't really gotten in to Bolt Cutters (rated 10.0 by Pitchfork), although I ought to give it another shot. My thought upon hearing it was that she's happier and more contented now, which is great for her but not as good for the work. (That change is also commonly a part of growing older, and hence related to why so many great songwriters of the last six decades have failed to sustain their levels past their early thirties.)

She also may have grown tired of writing from so far out on the edge. She has commented in interviews about how tough it is to perform songs that she wrote when she was upset about something, because it forces her to relive her worst moments while on stage. That concern might inspire the self-censoring self-protectiveness that her three previous albums avoided.

Stephin Merritt's response is to be completely self-protective. Nearly everything is layered deep in irony. 69 Love Songs, for example, is not "about" love - it's about love songs, indeed as promised by the title's double entendre. And not just love songs, but, through them, all the artificial or cliched or simplistic or overly self-conscious ways of thinking about love, instead of just experiencing it, to which we all fall victim given the huge cultural weight of all the "content" that we have absorbed about it.

True, he tried to fight against this in 50 Song Memoir, although part of what's going on there is that he likes to set difficult songwriting tasks for himself (e.g., one of his albums is limited to songs that begin with the latter i, and that appear in alphabetical order). But, although I thought parts of 50 Song Memoir were great, it's more uneven than 69 Love Songs, perhaps reflecting that this was a harder space for him to work in.

2024 NYU Tax Policy Colloquium

In a prior post, I had mentioned that the 2024 NYU Tax Policy Colloquium might need to shift to a new time, due to changes in the law school's scheduling blocks to accommodate multiple objectives. It now turns out that there will be less change than I had been thinking might be necessary.

We will still be meeting on Tuesdays (in fall 2024), and the start time has been moved slightly earlier, to 4:15 pm (ending at 6:15 pm, and followed by a small group dinner. There is a small chance that it will end up being moved earlier still, to a 4 pm start time.

We'll also be meeting in a new (for us) room, a bit out of the way in Furman Hall (across the street from the main law school building where we have always met in recent years), but in a true seminar room rather than a cavernous lecture theater.
