Lily Batchelder, Accounting for Behavioral Considerations in Business Tax Reform: The Case of Expensing
(Feb. 5, 2017), available at SSRN
Tax scholarship is interdisciplinary. To evaluate tax policy it helps to know at least a little about economics, a little about philosophy, something about budget processes, and a lot about the dizzying creativity of the marketplace in exploiting loopholes and facilitating tax-advantaged transactions. In her recent article Accounting for Behavioral Considerations in Business Tax Reform: The Case of Expensing, Lily Batchelder shows us that we must add financial accounting and firm (and corporate managers’) behavioral considerations to the mix.
The article evaluates which of three policies, adopted on a revenue neutral basis to replace our current regime of accelerated depreciation, would cause the largest increase in new investment by the corporate sector. The three policies are: expensing of new investments combined with higher statutory corporate rates; lower statutory rates combined with more gradual and economically accurate economic depreciation; and an investment tax credit combined with economic depreciation.
The conventional wisdom is that the first of these options, allowing for current expensing of new investment, will have the biggest bang-for-the-buck. But the analysis that yields this conclusion assumes that corporate managers choose investments to maximize the after-tax net present value of the investment returns. If that were true, managers would care about the marginal rate applicable to the investment, which is zero (at least as to the normal returns) if the investment is equity financed and the cost of the investment is expensed. The key insight that Batchelder shares is that managers don’t look at the marginal rate. The financial accounting literature shows that they make their decisions based on either the statutory rate or their “book” tax rate, because these are what affect income for financial reporting purposes. Neither rate reflects the value of tax deferral, so managers tend not to incorporate the benefits of tax deferral when making investment decisions. The best of the three policies is instead to eliminate accelerated depreciation and use the revenue to finance a statutory rate cut.
This paper makes two significant contributions. The first is to bring evidence on the tax variables that affect managers’ decisions to a live debate about how to increase investment. Batchelder not only canvasses relevant accounting theory and empirics, but also corroborates the incentives created by financial accounting standards by talking with corporate managers. The care with which she buttresses this important premise of her argument makes her conclusions about the ineffectiveness of expensing that much more credible. The second contribution is her argument that the optimal investment policy—at least in terms of maximizing the increase in new investment—is one that minimizes the capital-weighted relevant rate on new investment.
It doesn’t make sense to lower the marginal rate on new investment if the benefit is entirely inframarginal and generates no new investment. Different firms rely on different rates, and if we knew which rate each firm focused on, we might lower just that rate, for just that firm. Since that’s impracticable, Batchelder’s solution is to calculate the average target rate across all firms, weighted by the firms’ capital, and minimize that average. Note that this average rate isn’t the rate that is targeted by any one firm. To conclude that the optimal policy is the one that minimizes that average rate, Batchelder must assume that the elasticity of investment responses to changes in this rate are constant across firms, regardless of which rate they focus on. This assumption is worthy of further investigation. Presumably there is some reason that some firms focus on the statutory rate while others focus on the marginal rate. It could well be that the same managerial preferences, incentives, or constraints that cause some firms to focus on statutory rates also influence their investment behavior. If this were true, it could imply that a mix of policies, including investment tax credit, selectively available expensing, and lower statutory rates, might be the best approach.
Moreover, if deferral generally doesn’t matter to corporate managers, then we should also ask why we don’t provide for even slower depreciation or perhaps delay basis recovery at disposition in exchange for lower headline rates. Batchelder rightly notes that this would mean that firms will carry a lot of assets with built-in losses that could lead to asset churning, but this worry is in tension with the premise that there are very few firms that care about the timing of tax income and losses to begin with. If that’s the case, then we shouldn’t expect much churning after all.
Finally, a comprehensive analysis of these policy options would require some understanding of the tax sensitivities of non-corporate entities. Since the benefits of deferral accrue directly to investors in such entities, then we might expect that they would be more attuned to, and force managers to be more responsive to, the benefits of expensing. Batchelder’s data don’t allow her to calibrate her estimates by including these entities, but incorporating them would make for an important extension.
Understanding how policy interventions affect taxpayer behavior requires knowing the objectives of those taxpayers and the constraints that they face. Research in behavioral economics, particularly the literature on tax salience, has revealed some of the ways that individuals may not respond rationally to taxes. However, much less work has been done on the possibility that the assumption of economic profit maximization may fail in the case of firms. This paper is an important contribution in remedying this deficit in the scholarship.
In some sense, the marriage of accounting and tax law should be a natural one. Tax lawyers are accustomed to thinking about the pernicious consequences that flow when substance and form are allowed to come apart. They are sensitive to how taxpayers respond to labels such as “debt” and “equity,” or “employee” and “independent contractor” even when the underlying economic reality is the same. Accountants are engaged in a similar enterprise. It would seem that tax lawyers and accountants have a lot to talk about, and Lily Batchelder’s paper is a wonderful illustration of the important insights that can be generated from that conversation.
Andrew T. Hayashi, The Effects of Refund Anticipation Loans On the Use of Paid Preparers and EITC Take-up
,Virginia Law and Economics Research Paper No. 2016-9 (2016), available at SSRN
The conventional wisdom about refund anticipation loans, at least among many academics, is that they are predatory lending products that benefit big businesses at the expense of the poor. Andrew Hayashi turns this notion on its head in his insightful paper, The Effects of Refund Anticipation Loans on the Use of Paid Preparers and EITC Take-up.
Hayashi’s piece makes two important contributions to our understanding of tax-time financial products. First, he undertakes an empirical study that shows that curtailing refund anticipation loans (RALs) resulted in a decline in the use of tax return preparers, which in turn may have led to a drop in tax return filing and earned income tax credit (EITC) claims. Second, Hayashi discusses the welfare implications of RALs — an analysis that has been largely absent from the literature — and highlights the possibility that, on balance, they benefit taxpayers. Both of these insights have important implications for future policy, particularly for how we might regulate current and future tax-time products like refund anticipation checks.
The bad reputation of RALs is not entirely undeserved. Indeed, these loans were typically peddled by tax return preparers to their low-income clientele, and generally required repayment from the taxpayer’s refund at a high rate of interest plus fees, in some cases equivalent to as much as 700% on an annual percentage rate basis. A number of consumer advocate groups pushed for the elimination of RALs and, in 2010, a regulatory change virtually eliminated the RAL market (but for a small number of exceptions).
Hayashi’s empirical study focuses on this moment of regulatory change to examine the collateral effects of eliminating RALs in 2010. Using IRS data, he studied trends in the use of tax-time lending products, tax return preparers, and EITC claims in 2011, the year immediately following the elimination of RALs. He found that 80 percent of taxpayers formerly using RALs simply replaced them with another tax-time product: the refund anticipation check (RAC). Although RACs do not immediately accelerate the taxpayer’s refund like a RAL, they allow unbanked taxpayers to receive a direct deposit of their refund in a temporary bank account, and they also allow taxpayers to borrow their tax preparation fee (to be repaid from their refund with interest and fees).
Hayashi’s study also revealed that 10 percent of former RAL users switched from using preparers to self-preparation in 2011. Additionally, approximately 5 percent of former RAL users stopped claiming the EITC. Although the decline in EITC claims could potentially have come from those taxpayers who continued to use a preparer, it’s plausible that the shift away from preparer assistance may also have led to the decline in EITC claims. As Hayashi notes, other studies have demonstrated a positive correlation between tax preparation assistance and EITC take up.
Looking at the bigger picture, then, it appears RALs may have encouraged the use of tax preparation assistance. And, it appears that tax preparation assistance encourages taxpayers to file returns and claim the EITC. Thus, an important collateral consequence of curtailing RALs may be that we have deterred some taxpayers from filing and claiming vital benefits to which they are entitled. As Hayashi argues, these collateral consequences should not be overlooked by policymakers. Potential non-filing and failure to take-up government benefits like the EITC are a serious cost that must be weighed against the benefits of regulating tax-time lending products.
Hayashi’s paper makes another important contribution to the debate over RALs and RACs. It carefully discusses the costs and benefits of these products and points out that taxpayer preferences for them may not be irrational, notwithstanding high interest rates and fees. One important reason taxpayers take out RALs and RACs is that these products allow them to borrow their tax preparation fees when they cannot otherwise come up with the funds for tax assistance. Taxpayers might rationally prefer tax assistance because they lack Internet access and/or because of the time and complexity involved in self-preparation. Both products also help taxpayers access their refunds more quickly (although the timing advantage with a RAC is less immediate). Quicker access to refunds, in turn, may help taxpayers pay down debt sooner, which could be vital for individuals who are behind on payment of necessities like rent and utilities.
Thus, as Hayashi points out, some taxpayers may rationally prefer RALs and have been made worse off from a welfare standpoint as a result of their elimination. Other taxpayers, however, may be exhibiting some form of cognitive bias – present bias, for example – in their preferences for RALs. These taxpayers may be better off either self-preparing or paying out of pocket for tax preparation assistance, yet may have been tempted to take out a RAL because they wanted their funds sooner. In that case, regulation of RALs may be beneficial. The problem, Hayashi rightly notes, is that we don’t have data on the proportion of taxpayers that are acting rationally and irrationally.
This means that the answer to the question of whether tax-time products are bad for taxpayers overall is “we don’t know,” which is notably different than “yes” (the answer which I admittedly would have given before I read Hayashi’s piece). What’s perhaps most telling from Hayashi’s study is that a large majority of former RAL users still exhibit preferences for tax-time financial products, now in the form of a RAC, which is their only option at present for financing tax preparation fees. The welfare effects of switching from a RAL to RAC are also uncertain, Hayashi notes. Taxpayers who rationally chose RALs over RACs will be made worse off, while others (those whose bias led them to choose a RAL) may be made better off with a RAC.
Hayashi cautions regulators to think carefully before regulating RACs out of existence. Although charging low-income taxpayers fees that are deducted from an EITC refund certainly appears distasteful, this may be a vital mechanism to keep some individuals engaged in the tax system. If we don’t like this mechanism, it may be time to revisit the larger issue of how and when we deliver benefits like the EITC to the poor.

Tax transparency is all the rage these days. The brouhaha around the disclosure (or, in one instance, the non-disclosure) of presidential candidates’ tax returns during the 2016 presidential campaign brought the matter of tax transparency to the front and center of public discourse in the United States. Around the world, recent revelations that multinational corporations dramatically reduced their tax bills by securing secretive rulings from tax authorities, and that billionaires are able to use intricate offshore shell structures to evade taxation, are causing major popular uproar and a demand for increased transparency on tax matters. The demand is heard by intergovernmental as well as national bodies. For example, the Organisation for Economic Co-operation and Development (OECD) recently adopted country-by-country reporting standards, which would require multinational corporations to disclose to tax authorities their activities and tax payments in each country in which they operate. Remarkably, some countries have announced they are considering making the reports public. Another example is Luxembourg, which—responding to international criticism—recently announced it will start publishing redacted versions of advance tax agreements with taxpayers. This represents a dramatic shift in Luxembourg’s usual secretive tax stance.
Against this background, Joshua Blank’s article—The Timing of Tax Transparency—is both perfectly timed and profoundly instructive. Policy choices about whether to disclose tax return information as well as tax administrators’ enforcement actions to increase public scrutiny have generally been viewed as a balancing act between competing values. Increased transparency may improve tax authorities’ accountability and encourage taxpayers to avoid aggressive planning for fear of public backlash. On the other hand, increased transparency hurts taxpayers’ privacy and may provide aggressive taxpayers a clear picture of tax authorities’ inner workings, which in turn may impede tax authorities’ enforcement efforts. The main innovation in Blank’s paper is his abandonment this binary approach towards tax transparency (increased tax transparency: yes or no) in favor of a time-dependent approach (increased tax transparency: when?). Blank argues that the balancing act between the competing values involved plays out differently depending on when—during the administrative tax process—disclosure is made.
Blank suggests that we separately consider ex-post and ex-ante tax enforcement actions. Ex-post enforcement happens “after taxpayers have pursued transactions and claimed tax positions, such as by conducting audits or settlements.” Ex-ante enforcement refers to tax authorities’ engagement with a taxpayer, before that taxpayer takes a legal position in a tax return, for example, by “issuing advance tax rulings [and other] advance agreements with specific taxpayers.”
Blanks then turns to consider the pros and cons of disclosure of ex-post versus ex-ante administrative tax actions. He makes a strong case against mandatory disclosure of tax return information, which would include information about tax authorities’ ex-post enforcement action. Such disclosure, he argues, would impair tax authorities’ ability to strategically publicize their enforcement strengths and to positively influence public perception and compliance behavior by doing so. In addition, ex-post publicity may encourage aggressive tax behavior. For example, activist corporate shareholders may pressure corporate management to engage in aggressive behavior adopted by other corporations (a process Blank refers to as “benchmarking”). Finally, ex-post disclosure also enables aggressive tax planners to reverse-engineer tax authorities’ enforcement decisions (such as, which returns to audit), and thus engage in strategic behavior.
On the other hand, Blanks proposes that the disclosure of tax authorities’ ex-ante actions is justified. Ex-ante actions, in effect, “bless” taxpayers’ positions in advance. Tax rulings done in secret may hurt the social legitimacy of tax authorities. The public may perceive that the tax authority creates “secret” tax law for a select group of taxpayers, and treats taxpayer inequitably. The public may question the integrity of such process (as indeed happened in the recent Luxleaks scandal, where advance tax agreement were popularly referred to as “tax deals”). Ex-ante disclosure is also efficient according to Blank, since it encourages taxpayers to seek tax rulings, which in turn increases legal certainty of the tax treatment of proposed transactions. Blank also suggests that ex-ante disclosure does not suffer from the same ails of ex-post disclosure. Since advance tax rulings are generally non-binding outside the scope of the specific transaction to which they apply, it is unlikely that they serve as benchmark instruments for strategic behavior by other taxpayers. Moreover, it is unlikely that a ruling will be granted for a particularly aggressive plan, and thus no roadmap for bad behavior will be provided.
After presenting the theoretical case, Blank turns the explore some of its practical applications, which is where, in my mind, the article is most revealing. Blank’s theoretical framework offers a strong case for the disclosure of ex-ante actions that are currently not disclosed. For example, most advance rulings published by tax authorities are favorable to taxpayers. When a tax authority indicates that it will rule against the taxpayer, the ruling submission is usually withdrawn and as such never disclosed. Blank suggests that information on withdrawals of advance ruling applications should be disclosed. Without information on instances in which tax authorities declined to rule on a transaction, taxpayers may lack complete understanding of a tax authority’s ex-ante legal interpretation, which may reintroduce the problem of “secret tax law”. Another example is advanced pricing agreements (APAs) that determine the pricing (for tax purposes) of transactions between affiliated entities. APAs are currently undisclosed, in the United States (as well as in other countries), which may create suspicion that that tax authorities use them to facilitate tax avoidance by multinationals. Indeed, the European Commission has recently determined that certain APAs granted by tax authorities in Europe to multinationals violated European law. While the issue is hotly contested, few will disagree that these APAs would look the same if tax authorities and multinationals knew they would be publicized.
On the other hand, Blank’s framework offers some counterintuitive results for ex-post disclosure. For example, Blank’s framework seems to significantly weaken the case for public country-by-country reporting (which some see as a dramatic and positive achievement by the OECD). This is a counter-intuitive outcomes. I have my doubts about such outcome, but Blank’s paper will certainly cause me to revisit my perception of ex-post tax disclosure.
In any case, even if one were to reject some (or all) of Blank’s practical applications, Blank’s article offers an important contribution to the literature on tax transparency. It shifts the debate away from its seemingly binary nature, and offers a completely original approach to evaluating tax transparency. In doing so, Blank challenges us to think about tax transparency in an original and a more nuanced way, which generates counter-intuitive outcomes that demand further research.
Auer/Seminole Rock or “ASR” deference is a hot topic right now in administrative law. ASR gives agencies deference when agencies interpret their own regulations, such as in litigation briefs or in guidance. If you want to know how ASR deference works in the tax context, and in particular in the Tax Court, read Steve Johnson’s work. This includes his 2013 article and his entry in the Yale Journal of Regulation’s recent online symposium on ASR deference.
The Chevron doctrine often serves as the starting point for deference to agency action. Chevron offers judicial deference to agency interpretations in final regulations and other actions with the “force of law” articulated in Mead. When the Supreme Court confirmed in its 2011 Mayo decision that Chevron applies to tax regulations, it helped to usher in a growing awareness of administrative law doctrine in tax cases.
Agency action without force of law, including an agency interpretation of its own regulations, does not get Chevron deference. But it might get ASR deference. So what does that mean?
In the Tax Court, ASR historically doesn’t mean very much, as Johnson explains in his 2013 article. ASR claims may succeed at a rate of 91% at the Supreme Court and at a rate of 76% at federal circuit and district courts, but such claims, if they are made at all, are less likely to succeed in the Tax Court. Johnson sets forth six doctrinal exceptions that a court might rely on as support for not granting ASR deference. These include that agency’s action might be “plainly erroneous or inconsistent with the regulation” (Auer), that the regulation is unambiguous, that the agency’s position is unsettled, that the regulation “parrots” the statute, that regulated parties have not had fair notice of the interpretation, and that the agency’s interpretation “does not reflect the agency’s fair and considered judgment on the matter in question” (Auer).
Johnson shows how these exceptions can be made big enough to drive a truck through, if a court is so inclined. In his 2013 article, he catalogues the Tax Court cases that have refused deference to the Treasury’s interpretation of its own regulations between 1980 and 2011. In his online symposium contribution, he reviews more recent case law developments. In many cases, Johnson reports, the government does not even bother to argue ASR deference.
Johnson also tells of a 2014 case in which the government argued before the Tax Court that ASR deference applied. In that case, the Tax Court nimbly dodged the issue. It wrote, “The regulations are silent on the issue before us, and [the government’s] position on brief is at least arguably inconsistent with the statute.” This makes little sense. The fact that the regulations are silent should not block the government from offering an ASR-protected interpretation as to how the regulations should apply. But the Tax Court refused to defer.
Reasons for the Tax Court’s approach may include its status as an expert court. The Tax Court’s authorizing statute directs the court to determine the “correct” amount of tax and might be interpreted as a particularly broad mandate for review of agency action. But the Tax Court’s reluctance to embrace ASR deference could also indicate that the ASR doctrine in general is overbroad. Auer and Seminole Rock can be read to suggest that ASR gives as much deference to informal agency guidance as Chevron gives to final notice-and-comment regulations. Should this be the law? As others have suggested, perhaps the Supreme Court should clarify that ASR gives less deference to an agency’s interpretation of its regulations than Chevron gives to the regulations themselves.
There are three takeaways from Johnson’s work on ASR deference. First, tax law’s awkward relationship with administrative law is a work in progress. Second, sweeping language in a Supreme Court case doesn’t automatically translate to sweeping deference in practice. Third, tax law can influence administrative law, as well as the other way around. For purposes of the debate about the proper scope of ASR, the Tax Court’s reluctance to grant ASR deference might prove, as Johnson suggests, “less insubordinate than prescient.”
Kyle Rozema, Supply Side Incidence of Consumption Taxes
(Oct. 5, 2016), available at SSRN
Empirical testing of the tax laws, and in particular testing the incidence of the tax laws, may sound boring. But virtually any modern public policy goal that could be implemented through tax policy ultimately turns precisely on this question. For example: Should the United States adopt a tax on sugary drinks? Is a high cigarette tax effective in preventing smoking deaths? Would a carbon tax help to reduce global warming? Ultimately, the answers to these questions turns on who, in fact, ends up bearing the burden of these taxes.
Such proposals often represent forms of so-called Pigouvian taxes. Proponents of Pigouvian taxes support them by contending that they can be used to reduce inefficient behavior by forcing consumers to internalize the full costs of such activities. Opponents of Pigouvian taxes often point to the regressive effect of such taxes on consumers, because they increase the cost of goods by a fixed amount of taxes, which disproportionately harms those consumers least able to afford such taxes. A fair amount of literature has arisen to resolve this question, primarily focusing on the empirical question of whether increasing the price of certain goods through higher taxes in fact reduces the amount of consumption and who bears the costs of such taxes. Virtually none of the literature in this area asks a related, but equally important, question: how do Pigouvian taxes impact different types of sellers of such goods?
Kyle Rozema provides one of the first attempts to address precisely this question in his article Supply Side Incidence of Consumption Taxes. More specifically, Rozema asks: How does a cigarette tax affect sellers of goods, as opposed to buyers of goods? The question matters because if the purpose of the cigarette tax was to serve as a Pigouvian tax, it would work only if it actually increased the price of cigarettes to consumers. Ultimately, however, the behavior of both buyers and sellers determines the equilibrium price of the goods. As an initial matter, this seems like an obvious question. After all, a Pigouvian tax works by charging more for a good which, in turn, should reduce demand (depending on the shape of the demand curve). But what if sellers don’t, in fact, raise prices in response to the tax? Even worse, what if some do and some don’t? As becomes readily apparent, taxes that are not fully passed on through retail prices would be less effective at reducing consumption, thereby undermining the purpose of a Pigouvian tax in the first place.
For example, if the government were to charge a tax on sales of sugary drinks of $.05 but the retailer does not increase the price of the drink, was the Piguovian tax effective? The tax did make it more expensive for the retailer to sell the drink, but it did not make it more expensive for the consumer to buy the drink. Is this the intended result? In determining whether to adopt a Pigouvian tax in the first place, should it matter whether the tax would ultimately be borne by the buyer or seller? There is little hard evidence to answer these questions. In particular, empirically testing the effects of Piguovian-type taxes on the supply side of the analysis has proven particularly difficult due in part to a lack of sufficiently fine-grained data. The result is often the adoption of Piguovian taxes based on little more than intuition about the incidence or resorting to one’s normative priors.
Rozema’s primary contribution is to challenge the assumption that all sellers bear an equal burden of such taxes by compiling a unique dataset of actual sales by different retailers of cigarettes based on data compiled by actual scans of UPC codes at the register. In this manner, Rozema can obtain a glimpse not only of the macro-level effects of total consumption of cigarettes but also on the more micro-level effect of whether and to what extent the tax decreased sales at the register for different types of retailers and the amount of profits on such sales. By utilizing more precise data, Rozema unveils a more complex and nuanced picture of Pigouvian taxes. His analysis finds that a rise in the cigarette tax can result in different consequences for different types of retailers. In particular, he finds the effect of broad-based cigarette taxes on actual registered sales was to increase the price at most large drug and grocery stores but not to do so at convenience stores and other small retailers.
Why would this result be so important? Return to the sugary drink hypothetical above. Assume the goal of a tax on sugary drinks is to reduce the consumption of sugar in society. Now assume that Rozema’s findings apply equally to sugary drink taxes as to cigarette taxes. This could mean that people would buy fewer sugary drinks at gas stations and convenience stores, but this reduction would be offset by greater sales of sugary drinks at grocery stores or warehouse stores (for example, where bulk discounts are available). Alternatively, Rozema’s results could mean that gas stations and convenience stores would not increase retail prices but instead such sellers would absorb the cost of the tax, resulting in little to no reduction in consumption of sugary drinks at such retailers. Either way, what results is a distributional distortion among retailers rather than the desired Pigouvian effect of reducing consumption. Even worse, Rozema proposes that not only is there a distributional effect, when one was not anticipated, but that the effect could in fact prove regressive to the extent it tends to hurt smaller retailers over the larger retailers.
Rozema’s results are striking. Not only do they provide new insights in an area where many may have thought empirical analysis would be impractical, but they also potentially challenge many of the theoretical foundations underlying the use of Piguovian taxes. Rozema’s paper represents some of the best of what empirical tax research can and should do. It looks to an important area of tax and public policy, finds a significant gap in the micro-foundations for such policy, and uses a creative and novel data to begin to address that gap. Rozema attempts to shed light on the issue and clarify the trade-offs inherent in adopting Pigouvian taxes not only from a consumption side but also from a supply side.
While this review might still not have convinced many readers that empirical analysis of the incidence of taxes is not boring, keep these results in mind the next time you find yourself at a cocktail party debating whether the government should adopt an additional tax on liquor or wine. Maybe then empirical tax studies won’t seem so boring after all.
Tax specialists are no strangers to the exercise of statutory interpretation. The Internal Revenue Code is an enormously complex statute, with all of the overlapping provisions, competing goals, and specificity interspersed with ambiguity that one would expect to accompany that complexity. And mastering the tax policy aspects of the Code is hard enough that tax specialists might be forgiven for reducing the exercise of statutory interpretation to short statements about considering the Code’s text, history, and purpose, or the “spirit” of the tax laws. A recent exchange between two prominent federal judges—Chief Judge Robert Katzmann of the Second Circuit and Judge Brett Kavanaugh of the D.C. Circuit—and the lengthier books highlighted within their exchange offer a highly readable reminder of the parallel complexity of statutory interpretation theory and jurisprudence. Tax specialists interested in seeing their policy preferences succeed in the real world would do well to take note.
Although tax specialists often like to think of the tax laws as unique, judges in tax cases routinely rely upon and debate about the same tools of statutory construction that they apply and discuss in interpreting other statutes. Consider just one particularly expansive example. In Rand v. Comm’r, 141 T.C. 376 (2013), deciding that refundable credits like the earned income tax credit reduce “the amount shown as the tax by the taxpayer on his return” when computing the underpayment penalty under § 6662 and 6664, Judge Ronald Buch discussed the consistent usage canon, the expressio unius canon, the surplusage canon, and the rule of lenity, in addition to the Chevron and Auer standards of review. Judge David Gustafson in dissent maintained that proper application of the rule of lenity supported the opposite conclusion. Judge Richard Morrison, dissenting separately, criticized Judge Buch’s opinion for relying too heavily on the consistent usage canon and ignoring relevant legislative history. (Congress subsequently amended § 6664 to clarify its intent.) Also, Carpenter Family Investments, LLC v. Comm’r, 136 T.C. 373 (2011)—one of the cases leading up to the Supreme Court’s decision in United States v. Home Concrete that basis overstatements are not omissions of an amount from gross income under §§ 6229(c)(2) and 6501(e)(1)(A)—includes an interesting exchange between Judge Robert Wherry for the majority and Judges James Halpern and Mark Homes in concurrence over whether unique attributes of the tax legislative process are relevant when considering legislative history in tax cases. And in Yari v. Comm’r, 143 T.C. 157 (2014), in interpreting the phrase “tax shown on the return” in connection with the § 6707A reportable transaction penalty, Judge Robert Wherry referenced several canons, discussed at some length which documents were relevant as legislative history, and observed further that “the process of divining the legislative intent underlying a statute’s language and structure, while subject to canons of construction and well-established methodologies, is hardly an exact science.”
In a sense, Katzmann’s and Kavanaugh’s conversation about statutory interpretation theory and jurisprudence started when Katzmann published the well-received Judging Statutes in 2014. For that matter, although not styled precisely as such, Katzmann’s book could be read as responding to the also-acclaimed Reading Law: The Interpretation of Legal Texts, published by the late Justice Antonin Scalia and Professor Bryan Garner in 2012. As good textualists, Scalia and Garner rejected legislative history and emphasized semantic canons like the whole act rule and substantive canons like the rule of lenity. By comparison, Katzmann offered a robust and scholarly defense of legislative history as instructive in discerning congressional intent. As a key part of his argument, Katzmann contended that courts (and the rest of us) need to understand better how Congress operates in order to use legislative history appropriately.
In his review of Judging Statutes, Kavanaugh accepts the proposition that legislative history may be useful in resolving textual ambiguity. But he objects to relying on legislative history to override clear statutory text in the vein of Church of the Holy Trinity v. United States, 143 U.S. 457 (1892), and he criticizes Katzmann for failing to make that distinction. Kavanaugh observes further that many canons of statutory construction (including the “canon” of relying on legislative history to clarify textual ambiguity) “depend on an initial evaluation of whether statutory text is clear or ambiguous,” and he describes at some length why it is often difficult to determine where textual clarity ends and textual ambiguity begins. He suggests, therefore, that courts should reduce their reliance on those canons that turn on a threshold finding of textual ambiguity and instead “seek the best reading of the statute.” Kavanaugh offers ways in which several traditional tools of statutory construction that turn on the clarity/ambiguity distinction—from the application of legislative history to the Chevron standard—might be reframed to better facilitate the search for congressional intent. Other canons, like anti-consistency and consistent usage, he suggests using cautiously. Ejusdem generis, he suggests tossing outright.
In his response to Kavanaugh’s review, Katzmann first clarifies that he did not intend to suggest a return to Holy Trinity’s reliance on legislative history to override clear statutory text, but rather merely “to highlight the challenges of the interpretive task and approaches to addressing that challenge.” Katzmann also lauds Kavanaugh’s efforts to explore “how canons can be better employed as interpretive rules of the road . . . freed from an inquiry into ‘ambiguity.’” But Katzmann then poses a series of questions suggesting, for example, that seeking the best reading of a statute is what judges already do, and also that debates over clarity versus ambiguity and disagreements over best reading are both legitimate and inevitable whenever the words of a statute are not explicit.
In the end, Katzmann and Kavanaugh agree on critical starting points. Both start from the premise that the role of a judge (and, thus, anyone trying to read a statute) is to discern and comply with congressional intent. Both begin the interpretive process with statutory text. To quote Justice Kagan, as Kavanaugh does in his review, “we’re all textualists now.” Both Katzmann and Kavanaugh agree, though to substantially different degrees, that legislative history has a role to play in discerning congressional intent. But they disagree significantly over many of the details, wherein of course lies the devil.
This sophisticated conversation between Katzmann and Kavanaugh is a must-read for tax specialists for a couple of reasons. As sitting federal appellate court judges, Katzmann and Kavanaugh together offer a bird’s eye view into real-world judicial decisionmaking. Yet Katzmann’s book, Kavanaugh’s review, and Katzmann’s response not only offer examples from case law, but also draw extensively from the latest scholarship on statutory interpretation. Nevertheless, maybe because they are judges rather than scholars, Katzmann and Kavanaugh have made their conversation clear and easy to read, and thus accessible for audiences who are not so interested in a deep dive into that scholarly literature. Highly recommended for busy tax specialists who appreciate that they need to think more about statutory interpretation but want to get back to debating tax policy!

Emily Satterthwaite, Tax Elections as Screens
, Queen’s L. J.
(forthcoming 2016), available at SSRN
The concept of “screening” taxpayers is theoretically appealing. According to optimal tax theory, our tax system should impose tax liability based on ability, which is a characteristic that reflects relative well-being. However, since ability cannot be directly observed, the tax system has to rely largely on income, a presumed surrogate of ability, as a tax base. The problem is that income is easily manipulable, making the tax system an inefficient tax on ability. Screening is a potential, partial solution to this problem. Screening involves relying on other characteristics that are more revelatory of ability. For instance, as it turns out, height is surprisingly strongly correlated with earning ability. However, as theoretically appealing as screening may be, the discussion of it is generally politically unrealistic enough, or sufficiently divorced from the realities of the actual tax system, to make it a largely academic exercise.
In Tax Elections as Screens, Emily Satterthwaite gets beyond the theoretical possibilities of screening taxpayers. She does so by examining how an existing tax election—the election to itemize deductions—can serve as a screening mechanism. By examining how screening may work in our actual tax system, Satterthwaite offers an important contribution that has few companions in what is a largely theoretical field.
Satterthwaite begins by offering a simple model of the potential value of tax elections. She then goes on to illustrate what practical information the election to itemize may offer the government. She marshals evidence from an empirical study that, for taxpayers with income below $58,000, a taxpayer’s cost of itemizing cannot be inferred from observable characteristics on the taxpayer’s return (such as gross income). As a result, Satterthwaite posits that the election to itemize may reveal otherwise unobservable information about this income group.
Specifically, Satterthwaite posits that the election to itemize can reveal information about earning ability, how responsive a taxpayer is to taxation, and a taxpayer’s compliance posture. She then makes suggestions about how each of these various possibilities might shape tax policy. First, a taxpayer who is more conscientious is likely to have higher earning ability, and is also likely to face lower costs to engage in all of the tasks required to itemize (such as collecting, saving, and using deduction records). Satterthwaite suggests that the government may use this information to target various forms of assistance to non-itemizers, who are more likely to need it. Alternatively, a taxpayer may be more likely to itemize because the taxpayer is more responsive to incentives that reduce taxation, a quality that means the taxpayer is correspondingly likely to be more tax-elastic on other dimensions (for example, being more likely to change labor, savings, and other behavior in order to reduce tax liability). Satterthwaite suggests the government may therefore want to target higher marginal tax rates to non-itemizers, based on their low elasticity. As a final possibility, taxpayers who are more likely to itemize may also be more likely to take other steps (including aggressive tax reporting positions) to reduce tax liability. The government may therefore want to target more enforcement and auditing resources toward itemizers.
However, as Satterthwaite acknowledges, the analysis of exactly what the government should do in response to a taxpayer’s decision to itemize is quite complex. A taxpayer may be itemizing for any or all of the three reasons she posits (i.e., because the taxpayer is more conscientious, has lower tax-elasticity, or has a more aggressive compliance posture). What the government should do depends on the taxpayer’s dominant motive. For instance, if the taxpayer is itemizing because the taxpayer is more conscientious, the government would theoretically want to impose a higher rate of taxation (or the equivalent through higher auditing or the like) in response to the taxpayer’s higher ability. However, if the taxpayer is itemizing because the taxpayer is more tax elastic, this would be the exact wrong result. Ferretting out why the taxpayer is itemizing, all else being equal, would be difficult. Indeed, knowing whether a taxpayer is itemizing because the taxpayer has lower costs from itemizing, or just has more deductions, would itself be a difficult task. As Satterthwaite also acknowledges, determining whether it makes sense to introduce itemizing as a screen also presents other estimating difficulties, such as estimating the compliance costs of the election.
Despite these difficulties, Satterthwaite’s insights are important. First, whether optimal or not, the tax code does provide an election to itemize deductions. As a result, Satterthwaite does not need to prove that introducing itemizing as a screen is welfare enhancing. Rather, she merely needs to show that, given that the election is already in place, the election can provide the government valuable information. And she succeeds in this task. Perhaps the most useful insight is Satterthwaite’s suggestion that the government may use the failure to itemize (and the likely higher cost of itemizing) to target other assistance to the taxpayer, such as help preparing a tax return or enhanced information about government benefits that are provided through the tax code, such as the earned income tax credit. This suggestion is particularly helpful because, even without being able to determine definitively why a taxpayer failed to itemize, the government can reasonably imagine that a non-itemizing taxpayer is likely to be less well-informed or sophisticated in preparing government forms than a taxpayer who itemizes. Targeting greater assistance to the former than the latter may create welfare improvements at a low cost. Moreover, the suggestion harnesses information that can be gleaned from tax filing behavior to help improve the administration of unrelated welfare benefits that, whether rightly or wrongly, are already being provided through the tax code. This sensible, incremental improvement arises out of Satterthwaite’s real-world tax policy approach. This approach, which has much to commend it, merits more scholarly attention.
Edward Kleinbard, The Trojan Horse of Corporate Integration
, 152 Tax Notes

Edward Kleinbard’s The Trojan Horse of Corporate Integration critiques the U.S. Senate Finance Committee’s current proposal for corporate integration. This is an important read for those who have not yet come to grips with the forces at play in contemporary tax policy. Kleinbard refers to these forces as the “political economy agenda” behind the proposal. That agenda has as much to do with appearances relating to tax liabilities as it does with any cash actually being paid.
Most tax policy analysis has historically assumed that it is the amount of tax that is actually paid that matters most. Taxes paid are resources that are no longer available to the private sector; taxes not paid are not available to the public sector. At bottom, the tax policy challenge has usually been seen as balancing the deadweight losses that are inevitable with resources taken away from the private sector with the market failures associated with leaving deployment of all resources in private hands. This view of the impact of taxes is all well and good for economists to theorize about, but does not capture very much of the political decisions taking place in the real world about the type of taxation that should be adopted.
As Kleinbard points out, a significant portion of the “political economy agenda” behind the Senate Finance Committee proposal is simply to allow corporations to report paying lower taxes for financial accounting purposes, without lowering the overall taxes paid on corporate investment. The Senate Finance Committee proposal would do this by allowing a corporation to deduct from its tax base dividends paid from corporate income. But even as it allows the corporation this “dividends paid deduction” (DPD), the proposal would require the corporation to withhold tax from the dividends actually distributed to the shareholder. This withholding tax would not be treated as a liability of the corporation, and therefore would not be included in the corporation’s financial accounting reports reflecting the taxes it pays. Thus, the taxes imposed at the corporate level would be reduced, even though the total taxes on corporate earnings (taking into account both the tax on corporate income and the withholding tax) may not be.
The equivalence between the collection of taxes paid by a corporation on its own behalf and the taxes paid by the corporation as unrefunded withholding taxes remains uncertain. It will depend on many features relating to the design of the tax (including the preservation of tax exemption for certain domestic taxpayers and any mechanism available for credits for foreign taxpayers).
As Kleinbard also points out, the DPD often produces a similar result as the imputation credit approach to corporate integration, since in both approaches a payment made by the corporation is credited against the shareholder’s tax liability. In fact, the DPD approach may often produce greater tax liabilities if the withholding scheme does a poorer job than the credit imputation scheme of taking into account the particular characteristics of shareholders, including tax exempt or foreign status. (Incidentally, Kleinbard’s piece is a good place for those having lost track of the complexities of integration design to get back up to speed.)
But the DPD, unlike the imputation credit approach, would also have the salutary effect, from a political economy point of view, of making the burden of taxes on investments in US corporations appear to be less because the withholding tax would not be treated as a corporate tax for financial accounting purposes. Kleinbard intimates that no one should consider this as an actually accomplishing anything different. After all, he asks, “how stupid are we?”
The relevant research is still in progress, but at least some of it suggests that many groups of suppliers of capital may actually be that stupid, at least in the sense that the way that taxes are reported for financial purposes is important independently of the amounts ultimately paid. This may be true if the focus is on management incentives and perhaps even if the focus is on investor behavior. Kleinbard’s explication of this phenomenon is a good first step in helping the rest of us see the implications.
Kleinbard is especially dismayed at the possibility that the DPD would allow, more cleanly than other forms of integration, repatriation and distribution of the foreign income of US multinationals that has only been lightly taxed, if taxed at all, in any foreign jurisdiction without any additional corporate tax. This possibility is the not-so-very-well-hidden secret in the DPD approach to integration. Kleinbard does seem to acknowledge that this change could break the log jam that has previously blocked progress in corporation tax reform. But he decries the breaking of the log jam as wasting a chance to do something more significant.
We probably are not so stupid as to not see the political economy behind the DPD. But the best part of the Kleinbard contribution is its capacity for pointing out that we could really be that stupid when it comes to more generally neglecting the importance of the appearance of tax burdens rather than the burdens themselves. There is a real possibility that analysts and the investors they serve may respond favorably to the reporting of lower corporate taxes, even though investors’ overall burdens will not be reduced. Although Kleinbard takes no view on whether and when such responses dominate over actual tax payments, he reminds us well that we cannot ignore such possibilities when implementing corporate tax reform.
Lisa Philipps, Registered Savings Plans and the Making of Middle Class Canada: Toward a Performative Theory of Tax Policy
, 84 Fordham L. Rev.
(forthcoming 2016), available at SSRN
Analyses of tax policy are typically based on a familiar cost-benefit framework. There are important debates about which costs and benefits should be included (and which are measurable), but the standard formula is simple: (1) Describe the policy goal; (2) Present the costs and benefits of a policy that is meant to achieve that goal; and (3) Conclude that the policy is good or bad, depending on whether benefits exceed costs or vice versa.
In her important new article, Professor Lisa Philipps uses a Canadian tax policy debate to show that this approach is fundamentally misleading. Standard cost-benefit analysis—even if it is focused on inequality or other social outcomes— ignores the effect that adopting policies has on, as Philipps puts it, “the range of policy options considered thinkable.” (P. 102.) Tax policies can become embedded in the social system in a way that cannot be explained by standard cost-benefit analysis, and the resulting changes in social expectations can lead to self-defeating policy inertia.
Philipps’s article, which is part of a symposium in the Fordham Law Review entitled “We Are What We Tax,” adapts Judith Butler’s important work in feminist theory to analyze a seemingly technocratic question about tax incentives for saving. To some readers, this might seem a jarring combination, but the intersection of feminist theory and tax policy has become a growing and vibrant area of scholarly inquiry over the past few decades. This line of research is providing important theoretical and practical insights into tax policy debates that helpfully move the conversation past the usual neoliberal framework.
As noted, Philipps focuses on the social impact of tax incentives for saving in Canada. Philipps looks at changes in Canada’s tax policies over recent decades, showing how the government has increasingly relied on the tax system to encourage people to save for their retirements, through what are called “registered savings plans.” This approach is, however, only one possible response to the broader policy question, which is how a society can allow people to spend the latter years of their lives living a dignified retirement rather than either working themselves to death or being reduced to poverty when they can no longer work.
Another possible answer to that question is known in the United States as the Social Security system. Although that system is often understood as a system in which people pay taxes while working and then “get their money back” when they retire, Social Security is in fact financed on a pay-as-you-go basis, and there are no “accounts” into which payroll taxes are deposited. Although it is beyond the scope of this essay to discuss the issue in detail here, the fact is that pay-as-you-go systems and systems of personal deposit accounts are analytically identical in the aggregate. In one way or another, workers at any given time are reducing their consumption in order to allow former workers to stay alive, and in turn those current workers will be allowed to live without working at some point in the future. The means by which that system is financed cannot change that fundamental tradeoff.
Being analytically equivalent, however, does not mean that the two systems are socially or politically interchangeable. As Philipps points out, Canada made the choice to have its workers build nest eggs for their retirement years, and Parliament has experimented with various methods by which to use tax incentives to encourage people to save sufficient funds to live in some comfort during retirement. In that sense, much of the political discussion followed the standard pattern: (1) We need to get people to save more money, (2) The policies that we are adopting have succeeded in various ways and failed in various ways, and therefore (3) The policies need to be tweaked, enhanced, abandoned, and so on.
The Canadian policy of relying on private decisions to save was justified by the neoliberal gloss of “promoting individual self-reliance and familial responsibility to address human welfare needs” (P. 109). Even when supplemented by various tax incentives, however, the Canadian system has had a (completely predictable) negative distributional impact. Philipps’s insight, however, is not merely that private savings accounts have exacerbated inequality. She argues that the policy conversation is not merely a matter of saying, “Well, our current set of policies is not serving Canadians well in their retirement, so let’s put all possible ideas on the table to see what would work better.” Instead, the justifications for the private-saving approach to retirement became self-reinforcing, such that even the Canadians who are harmed by the system are now psychologically committed to its perpetuation.
How could that be? The idea behind the Canadian retirement system was not just a matter of telling middle class people that they had a personal responsibility to save for their retirement, but also of making retirement saving part of the very essence of middle class identity. Philipps writes: “To be an adult without a registered savings plan now threatens to place one on the margins of the social order” (P. 121). In other words, anyone who wishes to think of herself as a middle-class Canadian now automatically thinks that part of middle-class life will involve building retirement savings through registered plans.
This constructed social identity, however, has a surprisingly important impact on the policy debate. Because people aspire to be part of the middle class, and middle class identity includes being a rugged individual who saves for oneself and one’s kin, middle class Canadians (and those who hope to achieve that status) are now highly unlikely to approve of any plan to move away from a savings-based system to a macroeconomically equivalent pay-as-you-go system that looks like a Social Security plan. That is, people have learned that “being middle class” means sinking or swimming on one’s own, and because of that deeply embedded social expectation, any move to more explicitly acknowledge through policy that everyone is mutually dependent now somehow feels wrong.
This phenomenon is hardly limited to retirement savings. For example, basic financial principles make clear that the difference between owning and renting one’s residence is ultimately a matter of form and not substance, because the legal category of property ownership can be replicated through contractual agreements. Nonetheless, in the U.S. and Canada part of “the dream” is to be a homeowner. It does not seem to matter that the particulars of home ownership can be devastating for people when their houses lose value (as in the housing bust of 2008-10), or that good financial management should discourage putting all of one’s proverbial eggs in a single basket, because such cost-benefit considerations end up being overwhelmed by people’s psychological commitment to home ownership. A politician who suggests that home ownership is not a meaningful or appropriate goal will discover quickly that citizens strongly disagree.
And so it is now in Canada with respect to individually oriented retirement savings. As Philipps concludes: “Registered savings plans will endure not because they actually deliver the benefits they promise to most people but rather because they have been assimilated into Canadian middle-class identity” (P. 122). What would be viewed as a flawed and counterproductive policy that harms middle-class Canadians thus stumbles onward, because people have been taught to believe that there is a “right” middle-class way to save for retirement. The existing policy regime becomes its own justification.
In his book Capital in the Twenty-First Century, Thomas Piketty did us the great service of bringing the problems of wealth and income inequality to the fore. In the process, however, he also may have performed a bit of a disservice – making those problems seem simple, a mere function of the inequality r > g, where r is the rate of return to capital and g is the rate of economic growth. The solution, he suggested, was equally simple: a tax on wealth.
Bariş Kaymak and Markus Poschke, in The Evolution of Wealth Inequality over Half a Century: The Role of Taxes, Transfers and Technology, offer a more complex picture. They construct a general equilibrium model of the U.S. economy over the past half-century, incorporating (1) reduced income taxes on top earners (from a 45% effective rate for the top 1% in 1960 to a 33% effective rate in 2004, and from a 71% effective rate for the top 0.1% in 1960 to a 34% effective rate in 2004), (2) expansion of government transfers from 4.1% to 11.9% of GDP over the same period, and (3) higher pre-tax wage inequalities, which they attribute to technological change. (For these purposes, effective rate is defined as income taxes paid as a percentage of taxable income.) The question they ask and attempt to answer is: To what extent were the observed increases in wealth and income inequality over that period attributable to each of these changes or trends?
Income: Their answer with respect to income inequality is unequivocal: After taking into account standard general equilibrium adjustments, cuts in top rates had almost no effect on after-tax income distribution. Instead, the authors find that during the period studied, after-tax income inequality increased almost entirely because pre-tax income inequality increased.
Wealth: Their answer with respect to wealth inequality might strike some as counterintuitive. They find that an increasingly robust safety net (principally Social Security and Medicare) appears to have reduced incentives to save for the bottom 90%, resulting in increased wealth concentration at the top. Taken together, changes in U.S. tax and transfer systems explained nearly half of the observed rise in wealth concentration over the past half-century; the remainder was explained by increases in pre-tax income inequality.
Interactions: In addition, the two inequalities interacted in complex ways, intermediated by interest rates and prices:
Accumulation of additional wealth in response to tax cuts leads to a decline in the interest rate and an increase in the wage rate. The fall in the equilibrium interest rate discourages savings by lower wealth groups and exacerbates the direct effect of tax cuts on wealth inequality. As for income, the lower interest rate mitigates the rise in top incomes, while a higher wage rate benefits lower income groups as they live mainly off labor income.
By email to this reviewer, Prof. Kaymak explains the relationship between wealth inequality and wage rate increases as follows:
[T]he link from capital accumulation to the wage rate is an equilibrium effect …. As new wealth is channeled to production through investment, it generates a demand for additional labor since labor and capital are complements in production. Higher demand for labor then raises both employment (job creation effect) and wages. Of course, tax cuts could also change the labor supply behavior …. But we find this [latter effect] to be much weaker ….
Bottom line: greater inequality in wealth reduced income inequality by reducing the return to capital and increasing wages.
Finally, because general equilibrium adjustments take time, the authors predict that two or three more decades of increasing wealth concentration will result from policy and economic changes that have already occurred, at which point the top 1% will own about half of all U.S. wealth, up ten percentage points from their current share.
What should we make of all this?
First, general equilibrium analysis, although absolutely essential, is notoriously difficult and sensitive to assumptions. The authors note that their conclusions are inconsistent with those reached by some (Atkinson (2011) and Mertens (2013)), but consistent with those reached by others (Saez (2012)). Nonpartisans may want to take all such conclusions with at least a small grain of salt.
The authors might have distinguished between taxes on income from labor and taxes on income from capital, although these are difficult to tease apart. A priori, at least, we would expect different kinds of taxes to have different effects on savings and interest rates. Optimal tax theory, for example, conventionally assumes that taxes on income from capital depress savings, but that taxes on income from labor do not.
One wonders also whether some aspects of the U.S. tax system might have offset the results the authors describe through depressed demand for lower-wage labor. Accelerated and bonus depreciation may have encouraged the automation of less skilled jobs, for instance, and/or a largely territorial multi-national corporate tax system may have encouraged the offshoring of those same jobs as tariffs and other trade barriers were lifted.
With respect to the effect of offshoring, Prof. Kaymak observes, again by email:
For wages to rise through the equilibrium effect…, investment has to stay at home. We had run some simulations allowing for capital flight in early versions of our paper. What that does essentially is to mute the effect of top tax cuts on wealth inequality (interest rate does not fall in this case, so the bottom wealth groups do not curb savings as much). Income inequality in turn increases somewhat, because part of additional investment goes abroad, hence no wage gains for labor.
In other words, capital flight reduces wealth inequality but increases income inequality.
In any event, the paper makes an important contribution; its thoughtful analysis should persuade the reader that problems of wealth and income inequality are more complex than Piketty claims. Increases in the safety net that reduce disparities in consumption may exacerbate disparities in wealth. Ed Kleinbard, in his book We Are Better Than This, has urged that we worry less about progressivity in taxation and more about progressivity in spending. Doing so, the current paper suggests, may actually result in further concentrations of wealth in the already wealthy.
This, in turn, raises fundamental normative questions: Do we really care about disparities in wealth? Why? Do we care more about disparities in income? Or is our ostensible concern about inequality really a concern about poverty? If Kaymak and Poschke are even partly right, it may not be enough to say: “Equality good. Inequality bad.” We may actually have to do some hard normative work.
