    Before: ROGERS and TATEL, Circuit Judges, and
    RANDOLPH, Senior Circuit Judge.
    Opinion for the Court by Circuit Judge ROGERS.
    ROGERS, Circuit Judge: In 2006, Congress passed the
    Postal Accountability and Enhancement Act, which directed
    the Postal Regulatory Commission to establish a ratemaking
    system to govern the prices set by the U.S. Postal Service for
    its market-dominant products. Although Congress left many
    details to the Commission, it forbid rates from increasing faster
    than the rate of inflation. The Commission was also required
    to assess after ten years whether the system had achieved nine
    objectives. If not, then the Commission could modify the
    ratemaking system or adopt an alternative one. This case arises
    from that mandatory ten-year review.              In 2017, the
    Commission found that the existing ratemaking system was
    3
    deficient and had not maintained the Postal Service’s financial
    stability. After extensive review, it adopted a new system in
    2020, which retains the price cap generally but allows above-
    inflation rate increases to target specific costs. Order 5763:
    Order Adopting Final Rules for the System of Regulating Rates
    and Classes for Market Dominant Products, Docket No.
    RM2017-3 (P.R.C. Nov. 30, 2020), 
    85 Fed. Reg. 81,124
     (Dec.
    15, 2020) (“Order 5763”).
    Groups whose members purchase postal products
    (“Mailers”) and the Postal Service seek review of the
    Commission’s new ratemaking system. The Mailers oppose
    any new rate authority. They contend that the system is
    inconsistent with the statute that gives the Commission its
    regulatory authority and is arbitrary and capricious. In
    contrast, the Postal Service contends that the Commission’s
    new ratemaking system is irrational because it does not confer
    enough rate authority. The Commission responds that its
    actions are authorized by statute and reasonably explained.
    For the following reasons, the court concludes that the
    Commission acted within its authority under the
    Accountability Act, and that its predictive judgments and
    economic conclusions satisfy the Administrative Procedure
    Act’s requirement of reasoned decision-making. Accordingly,
    the court denies the petitions for review.
    I.
    By way of introduction, a summary of the Accountability
    Act is followed by a summary of the proceedings before the
    Commission.
    4
    A.
    For much of the Nation’s history, postal services were
    administered by the Post Office Department at rates fixed by
    Congress. See Nat’l Ass’n of Greeting Card Publishers v. U.S.
    Postal Serv., 
    462 U.S. 810
    , 813 (1983) (“Greeting Card
    Publishers”). In 1970, Congress relinquished control of
    ratesetting and replaced the Post Office Department with two
    independent executive agencies: the United States Postal
    Service and the Postal Rate Commission. See Postal
    Reorganization Act of 1970, Pub. L. No. 91-375, §§ 201–02,
    3601, 84 Stat. 719, 720, 759. Superintended by a Board of
    Governors, consisting of experts in economics, accounting,
    law, and public administration, 39 U.S.C. § 502(a), the Postal
    Service was required to set rates equal to costs with the goal of
    breaking even. See Greeting Card Publishers, 
    462 U.S. at 813
    .
    To guide the Postal Service, Congress charged the Postal Rate
    Commission (later renamed the Postal Regulatory
    Commission) with reviewing the Board’s rate proposals. See
    
    id. at 813
    –14.
    In 2006, Congress modernized the Postal Service in the
    Postal Accountability and Enhancement Act (“Accountability
    Act” or “Act”), Pub. L. No. 109-435, 120 Stat. 3198 (2006).
    Section 201 of the Act, 39 U.S.C. § 3622, “completely
    reformed the ratemaking system for market-dominant
    products,” i.e., those “products for which the Postal Service
    enjoys a statutory monopoly, or for which the Postal Service
    exercises sufficient market power so that it can effectively
    dictate the price of such products without risk of losing much
    business to competing firms.” U.S. Postal Serv. v. Postal
    Regul. Comm’n, 
    785 F.3d 740
    , 744 (D.C. Cir. 2015) (citing 39
    U.S.C. § 3642(b)(1)–(2)). The Act required the Commission
    to “establish” within eighteen months “a modern system for
    regulating rates and classes for market-dominant products.” 39
    5
    U.S.C. § 3622(a). The system had to “be designed to achieve
    [nine] objectives, each of which shall be applied in conjunction
    with the others,” id. § 3622(b), taking fourteen “[f]actors” into
    account, id. § 3622(c). The Act further enumerates five
    “[r]equirements” that the ratemaking system “shall” contain.
    Id. § 3622(d).
    Pertinent here, the Act mandates that the ratemaking
    system “include an annual limitation on the percentage changes
    in rates . . . equal to the change in the Consumer Price Index.”
    Id. § 3622(d)(1)(A). This prevents rates for market-dominant
    products from rising faster than the inflation rate. See U.S.
    Postal Serv., 785 F.3d at 744. The hope was that moving from
    a cost-of-service model to a price cap would incentivize the
    Postal Service to cut costs and improve efficiency. See S.
    Comm. on Gov’t Affairs, Postal Accountability and
    Enhancement Act, S. REP. 108-318, at 9 (2004). The Postal
    Service may exceed the price cap if the Commission finds, after
    notice and comment, that a rate change is warranted due to
    “extraordinary or exceptional circumstances” if “reasonable
    and equitable and necessary” to maintain postal services. 39
    U.S.C. § 3622(d)(1)(E).
    The Accountability Act provides the Commission two
    ways to change the ratemaking system. First, the Commission
    may “revise” the system “from time to time.” Id. § 3622(a).
    Second, the Commission must assess ten years after the Act’s
    passage “if the system is achieving the objectives in subsection
    (b), taking into account the factors in subsection (c).” Id.
    § 3622(d)(3). “If the Commission determines, after notice and
    opportunity for public comment, that the system is not
    achieving the objectives,” then it “may, by regulation, make
    such modification or adopt such alternative system for
    regulating rates . . . as necessary to achieve the objectives.” Id.
    6
    B.
    In December 2017, the Commission released the findings
    of its ten-year review. Order 4257, Docket No. RM2017-3
    (P.R.C. Dec. 1, 2017). It found that “while some aspects of the
    system” had “worked as planned, overall[] the system has not
    achieved the [Act’s] objectives.” Id. at 5. The Commission
    explained that the “operating environment” of the Postal
    Service “changed quickly and dramatically” after the Act’s
    passage. Id. at 45. The “Great Recession” of 2008 resulted in
    the most severe decline in mail volumes since the Great
    Depression of the 1930s, causing the Postal Service’s revenue
    to plummet. Id. at 38. The period of deflation after the Great
    Recession meant the Postal Service could not increase rates due
    to the statutory price cap. Id. Throughout, the Postal Service’s
    costs soared due to an obligation imposed on it by the
    Accountability Act requiring the prefunding of retirement
    benefits. Id. at 37. As a result, the Postal Service accumulated
    a $59.1 billion deficit in just ten years. Id. at 171.
    Given those findings, the Commission determined that the
    existing ratemaking system failed to achieve three statutory
    objectives. First, the system had not maintained the financial
    stability of the Postal Service. Id. at 178. Although the Postal
    Service could cover its immediate operating expenses, id. at
    159–65, it had not achieved “medium-term stability” as it had
    suffered a net loss for ten straight years, id. at 165–69. Nor had
    the Postal Service achieved “long-term stability” because it
    lacked the funds to invest in capital improvements or pay down
    debts. Id. at 169–71. Second, the system had not maximized
    incentives to cut costs and improve efficiency. Id. at 226.
    Despite the Postal Service having reduced costs, id. at 191, and
    improved its efficiency, id. at 203–21, the ratemaking system
    did not maximally incentivize such efforts because they “were
    insufficient to address the Postal Service’s financial
    7
    instability,” id. at 222. Third, the system had not achieved
    reasonable rates “because certain products and [mail] classes
    threatened the financial integrity of the Postal Service.” Id. at
    236.
    Concurrent with its findings, the Commission proposed “a
    two-pronged solution designed to place the Postal Service on
    the path to financial stability by providing [it] rate adjustment
    authority in addition to the CPI-U rate authority.” Order 4258,
    Docket No. RM2017-3, at 37 (P.R.C. Dec. 1, 2017). To
    address medium-term financial stability, the Commission
    proposed authorizing the Postal Service to raise rates annually
    by an additional 2% per mail class for five years. Id. at 45.
    This would “put the Postal Service on the path to medium-term
    financial stability by providing [it] the opportunity to generate
    additional revenue to cover its obligations.” Id. at 38. As for
    long-term financial stability, the Commission proposed a
    performance-based rate authority, which conditioned a 1%
    annual rate increase on hitting various benchmarks. Id. at 39.
    In addition to these rate authorities, the Commission also
    proposed mandating rate increases for mail products whose
    costs exceeded revenue. Id. at 77–78.
    In response to comments, the Commission issued a revised
    ratemaking proposal in December 2019. Order 5337, Docket
    No. RM2017-3 (P.R.C. Dec. 5, 2019). In place of an across-
    the-board annual rate increase, the Commission proposed two
    rate authorities targeted to “costs that are outside of the Postal
    Service’s control”: declines in mail density and statutorily
    mandated retirement payments. Id. at 12. First, the
    Commission found that decreases in mail volume in concert
    with the Postal Service’s statutory obligation to service every
    address had resulted in a decline in mail density, i.e., the ratio
    of mail pieces to delivery points. Id. at 70. This, in turn, raises
    the cost of delivering each piece of mail. To account for these
    8
    costs, the Commission proposed allowing the Postal Service to
    raise rates annually by the amount by which per-unit costs are
    expected to increase based on the change in mail density in the
    prior year. Id. at 77. Second, the Commission found that
    “congressionally mandated [retirement] payments are outside
    of the Postal Service’s direct control” but “continue to be one
    of the primary drivers of net loss.” Id. at 90. The Commission
    proposed allowing the Postal Service to raise rates annually by
    the amount necessary for revenues to cover these payments. Id.
    at 91–92. According to the Commission, its modified proposal
    was “intended to go beyond the initial supplemental rate
    authority’s goal of placing the Postal Service on the path to
    medium-term financial stability by providing the mechanisms
    necessary for the system to adjust appropriately to changes in
    the operating environment that are driving the Postal Service’s
    net losses.” Id. at 13.
    In Order 5763, issued in November 2020, the Commission
    adopted this new ratemaking system with minor adjustments.
    As an initial matter, the Commission rejected the Mailers’
    argument that it had to reopen the record to examine the impact
    of the COVID-19 pandemic on the Postal Service, reasoning
    that “nothing specific to the pandemic undermines the findings
    [it] made in Order No. 4257.” Id. at 26. In the new ratemaking
    system, the Commission adopted the density-based and
    retirement-based rate authorities, concluding that they were
    “necessary to achieve the objectives of [39 U.S.C. § 3622(b)],
    in conjunction with each other” and “focused on vital near-term
    improvements.” Id. at 298. The Commission withdrew the
    proposed performance-based rate authority but adopted the rate
    increases for non-compensatory mail products. Id. at 21–22.
    The Commission stated that it would review the new system in
    five years, or sooner if necessary. Id. at 23, 267.
    9
    The Mailers and the Postal Service petitioned for review
    of Order 5763. The Mailers unsuccessfully petitioned for stays
    by the Commission and by the court. See D.C. Cir. Order, Doc.
    No. 1887800 (Mar. 1, 2021); Order 5818, Docket No.
    RM2017-3 (P.R.C. Jan. 19, 2021). In July 2021, the
    Commission approved a proposal of the Postal Service to
    increase rates for market-dominant products. See Order 5937,
    Docket No. R2021-2 (P.R.C. July 19, 2021). The Mailers again
    unsuccessfully petitioned for a stay by the court. See D.C. Cir.
    Order, Doc. No. 1911271 (Aug. 24, 2021). The new prices
    took effect on August 29, 2021. Order 5937.
    II.
    The Mailers contend that Order 5763 exceeded the
    Commission’s statutory authority and is arbitrary and
    capricious.
    A.
    First, the Mailers maintain that the Commission exceeded
    its statutory authority in allowing the Postal Service to raise
    rates in excess of inflation because § 3622 unambiguously
    forecloses the Commission from altering the price cap. Mailers
    Br. 19–24. Even were the Act susceptible to multiple
    interpretations, the Mailers maintain that the new ratemaking
    system is “irreconcilable with the Commission’s prior
    understanding of the price cap” and is thus unreasonable. Id.
    at 25. Finally, the Mailers maintain that the constitutional
    avoidance canon counsels against the Commission’s
    interpretation because § 3622(d)(3) is otherwise an
    unconstitutionally standardless delegation of authority. Id. at
    26–30.
    10
    Under the two-step framework in Chevron, U.S.A., Inc. v.
    Natural Res. Def. Council, Inc., 
    467 U.S. 837
     (1984), the court
    first deploys the “traditional tools of statutory construction” to
    determine “whether Congress has directly spoken to the precise
    question at issue.” 
    Id. at 842
    –43 & n.9. If so, the court “must
    give effect to the unambiguously expressed intent of
    Congress.” 
    Id. at 843
    . If, however, “the statute is silent or
    ambiguous with respect to the specific issue,” the court will
    defer to the Commission’s interpretation if it is “a permissible
    construction of the statute.” Id.; see United Parcel Serv. v.
    Postal Regul. Comm’n, 
    890 F.3d 1053
    , 1061–62 (D.C. Cir.
    2018).
    Consequently, the court “begin[s] with the language
    employed by Congress and the assumption that the ordinary
    meaning of that language accurately expresses the legislative
    purpose.” Engine Mfrs. Ass’n v. S. Coast Air Quality Mgmt.
    Dist., 
    541 U.S. 246
    , 252 (2004) (citation omitted).
    Subsection 3622(d)(3) provides:
    Ten years after the date of enactment of the Postal
    Accountability and Enhancement Act and as
    appropriate thereafter, the Commission shall review
    the system for regulating rates and classes for market-
    dominant products established under this section to
    determine if the system is achieving the objectives in
    subsection (b), taking into account the factors in
    subsection (c). If the Commission determines, after
    notice and opportunity for public comment, that the
    system is not achieving the objectives in subsection
    (b), taking into account the factors in subsection (c),
    the Commission may, by regulation, make such
    modification or adopt such alternative system for
    regulating rates and classes for market-dominant
    products as necessary to achieve the objectives.
    11
    39 U.S.C. § 3622(d)(3) (emphasis added).
    The plain text contemplates two types of change: the
    Commission can “make [] modification[s]” to the ratemaking
    system or it can “adopt [an] alternative system.” The word
    “modification” means to make a “limited change in
    something.”           Modification,      Merriam-Webster.com,
    https://www.merriam-webster.com/dictionary/modification.
    In contrast, “alternative,” when used as a noun, describes a
    “situation offering a choice between two or more things only
    one of which may be chosen.” Alternative, Merriam-
    Webster.com,                https://www.merriam-webster.com
    /dictionary/alternative. By its plain terms, then, the provision
    permits the Commission to either make minor changes to the
    ratemaking system or replace it altogether.
    The Mailers do not contest this interpretation. Instead,
    they argue that the alternative ratemaking system adopted
    under § 3622(d)(3) must incorporate the price cap. They
    submit that § 3622(d)(1) precludes the Commission from
    altering the price cap because it is a “[r]equirement[]” that the
    “system for regulating rates and classes for market dominant
    products shall[] include.” Mailers Br. 19–20. But “[a] standard
    principle of statutory construction provides that identical words
    and phrases within the same statute should normally be given
    the same meaning.” Powerex Corp. v. Reliant Energy Servs.,
    Inc., 
    551 U.S. 224
    , 232 (2007). In § 3622(a) and (d)(1)(A),
    “system” refers broadly to a scheme for “regulating rates and
    classes for market-dominant products,” not to the subset of
    schemes that comply with the price cap. Therefore, absent
    evidence that Congress had a contrary intent, “system” most
    logically means the same in § 3622(d)(3), and includes rules
    that do not comply with the price cap.
    12
    The Mailers further contend that because § 3622(d)(3)
    permits the Commission to review the system “established
    under” § 3622, any alternate system adopted must also comply
    with all of § 3622’s requirements. Their conclusion does not
    follow. Whatever meaning the Mailers give to the word
    “under,” the phrase “established under” modifies only the
    system the Commission may review, not the alternative system
    it may adopt. Congress knew how to limit the Commission’s
    authority following the ten-year review and yet declined to
    require it to maintain the rate cap. Subsection (d)(3) requires
    that any changes to the system be “necessary to achieve the
    objectives” in § 3622(b), but makes no mention of the rate cap.
    The Mailers also invoke the presumption in Russello v.
    United States — that the inclusion of a phrase in one provision
    and its absence in another is deliberate, 
    464 U.S. 16
    , 23 (1983)
    — to argue that the exception to the price cap for emergencies
    in § 3622(d)(1)(E) demonstrates that Congress decided not to
    grant the Commission the authority to override the price cap in
    § 3622(d)(3). Mailers Br. 20–21. That canon has limited force
    here, however, because the two provisions use different words
    and are not otherwise parallel. See City of Columbus v. Ours
    Garage & Wrecker Serv., Inc., 
    536 U.S. 424
    , 435–36 (2002).
    Section 3622(d)(1)(E) is only meaningful insofar as a price cap
    exists, so it is unsurprising that it references the cap.
    The Mailers’ narrow interpretation of § 3622(d)(3) would
    also render § 3622(a) superfluous. See Mail Order Ass’n of
    Am. v. U.S. Postal Serv., 
    986 F.2d 509
    , 515 (D.C. Cir. 1993)
    (canon against surplusage). In addition to directing the
    Commission to “establish” a ratemaking system, § 3622(a) also
    provides that the Commission may “revise” the system “from
    time to time thereafter by regulation.” 39 U.S.C. § 3622(a).
    The Mailers’ interpretation of § 3622(d)(3) would render these
    words surplusage: if the price cap is an immutable feature of
    13
    the ratemaking system, then there is no meaningful difference
    between the Commission’s authority to “revise” the
    ratemaking system and its authority to adopt an “alternative”
    ratemaking system after ten years.            In contrast, the
    Commission’s authority to revise the ratemaking system under
    § 3622(a) suggests that its authority following the ten-year
    review must be broader under § 3622(d)(3): the former allows
    the Commission to make modest changes to the ratemaking
    system at its discretion while the latter authorizes the
    Commission to replace the existing system if, after ten years, it
    concludes that the existing system has failed to achieve the
    Act’s objectives. Broad authority under § 3622(d)(3) would be
    consistent with the more onerous procedural requirements
    imposed by that section, which requires notice and comment
    and a determination that the current system is not achieving the
    statutory objectives.
    The legislative history supports the Commission’s
    interpretation. See Pharm. Rsch. & Mfrs. of Am. v. Thompson,
    
    251 F.3d 219
    , 224 (D.C. Cir. 2001). Section 3622(d)(3) was
    not in the versions of the bills initially passed by the House and
    Senate; the Senate bill retained a price cap while the House bill
    contained a price cap that could be eliminated after notice and
    comment. H.R. 22, 109th Cong. § 201(a) (as passed by House,
    July 26, 2005); H.R. 22, 109th Cong. § 201(a) (as passed by
    Senate, Feb. 9, 2006). Subsection (d)(3) was added during the
    House-Senate Conference and thereafter enacted by both
    Houses of Congress. See 152 Cong. Rec. H9160–H9182 (daily
    ed. Dec. 8, 2006); id. at S11,821–S11,822 (daily ed. Dec. 8,
    2006). The primary Senate sponsor of the conference bill,
    Senator Susan Collins, addressed the provision on the floor of
    the United States Senate:
    After 10 years, the Postal Regulatory Commission
    will review the rate cap and, if necessary, and
    14
    following a notice and comment period, the
    Commission will be authorized to modify or adopt an
    alternative system.
    While this bill provides for a decade of rate stability,
    I continue to believe that the preferable approach was
    the permanent flexible rate cap that was included in
    the Senate-passed version of this legislation. But, on
    balance, this bill is simply too important, and that is
    why [the conferees] have reached this compromise to
    allow it to pass. We at least will see a decade of rate
    stability, and I believe the Postal [Regulatory]
    Commission, at the end of that decade, may well
    decide that it is best to continue with a CPI rate cap in
    place. It is also, obviously, possible for Congress to
    act to reimpose the rate cap after it expires.
    152 Cong. Rec. S11,675 (daily ed. Dec. 8, 2006) (statement of
    Sen. Collins). The Senator’s remarks reinforce the plain
    meaning of the statutory text: during its ten-year review, the
    Commission may adopt an alternative system and is not
    necessarily constrained the price cap.
    The Mailers additionally maintain that the Commission’s
    interpretation of the statute runs afoul of the nondelegation
    doctrine and should be rejected on constitutional avoidance
    grounds. Mailers Br. 26–30. But this argument, too, is
    unavailing. A statutory delegation of authority is constitutional
    so long as Congress has provided an “intelligible principle to
    which the person or body authorized to [act] is directed to
    confirm.” Whitman v. Am. Trucking Ass’ns, 
    531 U.S. 457
    , 472
    (2001) (quoting J.W. Hampton, Jr., & Co. v. United States, 
    276 U.S. 394
    , 409 (1928)). To date, the Supreme Court has found
    “the requisite ‘intelligible principle’ lacking in only two
    statutes, one of which provided literally no guidance for the
    15
    exercise of discretion, and the other of which conferred
    authority to regulate the entire economy on the basis of no more
    precise a standard than stimulating the economy by assuring
    ‘fair competition.’” 
    Id. at 474

     (1935); A.L.A. Schechter Poultry Corp. v.
    United States, 
    295 U.S. 495
     (1935)). Section 3622(d)(3), by
    contrast, provides an intelligible principle to guide the
    Commission by requiring that alterations to the ratemaking
    system be “necessary to achieve the objectives” in § 3622(b),
    which enumerates nine criteria.
    B.
    The Mailers next contend that the Commission’s
    ratemaking system is arbitrary and capricious because it fails
    to achieve statutory objectives. They also raise issues with the
    density-based rate adjustment specifically and contend that the
    Commission erred by not updating its analysis in response to
    the COVID-19 pandemic. Mailers Br. 30–48.
    Here, the court’s review is deferential, reflecting
    “‘reluctan[ce] to interfere with [an] agency’s reasoned
    judgments’ about technical questions within its area of
    expertise.” Alliance of Nonprofit Mailers v. Postal Regul.
    Comm’n, 
    790 F.3d 186
    , 197 (D.C. Cir. 2015) (quoting NRG
    Power Mktg., LLC v. FERC, 
    718 F.3d 947
    , 953 (D.C. Cir.
    2013)). An agency need only articulate a “rational connection
    between the facts found and the choice made.” Motor Vehicle

    463 U.S. 29
    , 43 (1983) (internal quotation omitted).
    Two features of Order 5763’s regulatory regime weigh in
    favor of deference. First, the Accountability Act requires the
    Commission to consider nine objectives. 39 U.S.C. § 3622(b).
    “[O]ur review of agency decisions based on multi-factor
    16
    balancing tests . . . is necessarily quite limited. We may not
    merely substitute the balance we would strike for that the
    agency reached.” U.S. Postal Serv. v. Postal Regul. Comm’n,
    
    963 F.3d 137
    , 141 (D.C. Cir. 2020) (quoting USAir, Inc. v.
    Dep’t of Transp., 
    969 F.2d 1256
    , 1263 (D.C. Cir. 1992)).
    Second, the Commission’s decision depends on “predictive
    judgments about the likely economic effects of a rule,” which
    are “squarely within the ambit of the Commission’s expertise.”
    Newspapers Ass’n of Am. v. Postal Regul. Comm’n, 
    734 F.3d 1208
    , 1216 (D.C. Cir. 2013) (alteration adopted; citation
    omitted). The court’s “narrow task” is thus “to ensure that the
    Commission sufficiently supported its analysis.” 
    Id. 1
    .
    The Mailers maintain that the Commission’s ratemaking
    system is arbitrary and capricious because it will both “upset
    the prior system’s successes in achieving multiple objectives”
    and “aggravate” its “failure to achieve other objectives.”
    Citing the statutory objectives in § 3622(b), they contend the
    new system will weaken incentives to cut costs, harm rate
    predictability and stability, render rates unjust and
    unreasonable, reduce transparency, and exacerbate the existing
    system’s failure to incentivize efficiency improvements.
    Mailers Br. 31, 33–34.
    Maximizing incentives to improve efficiency: Before the
    Commission, the Mailers argued that giving the Postal Service
    additional rate authority would weaken incentives to be more
    economical and efficient because the Postal Service would
    cover its costs through rate increases. Comments, Alliance of
    Nonprofit Mailers, at 14–18 (Feb. 3, 2020). The Commission
    disagreed. Order 5763 at 298–310. It stated that although a
    price cap “[t]heoretically” incentivizes the regulated entity to
    reduce costs and increase efficiency, the Act had failed to do
    17
    so because factors outside of the Postal Service’s control had
    resulted in its costs far exceeding its revenues. Id. at 301–02.
    Therefore, the Commission explained, “providing the Postal
    Service with the needed pricing tools to narrow the existing
    formidable gap between revenues and costs” would incentivize
    the Postal Service “to bridge that gap fully via efficiency gains
    and cost reductions.” Id. at 303. Further, the Commission
    found that the supplemental rate authorities would not weaken
    efficiency incentives because they compensate the Postal
    Service for costs that are “largely outside of its direct control.”
    Id. at 304. “By closely tailoring the modifications” to these
    exogenous costs, the Commission can “provide correct
    incentives and . . . encourage prudent pricing and operational
    decision-making by the Postal Service.” Id. at 302.
    Maintaining predictable and stable rates: The
    Commission found unpersuasive the Mailers’ argument that
    the new ratemaking system would produce excessive price
    hikes, explaining that the rate authorities limit the maximum
    allowable annual rate increase. Id. at 312. It also concluded
    that “[t]his concern fails to account for the Commission’s
    findings and analysis, which extensively discusses the
    deficiencies of the existing ratemaking system,” namely that it
    failed to maintain the Postal Service’s financial stability and
    resulted in unreasonably low rates. Id. at 313. The
    Commission further found that the Mailers’ concern
    overlooked that the Postal Service has “inherent incentives to
    exercise business judgment” and not raise rates too sharply. Id.
    at 314. Further, the use of rate formulas would minimize
    unpredictable price fluctuations and allow for forecasting. Id.
    at 315.
    Increasing transparency: The Commission found that the
    new ratemaking system was consistent with the statutory
    objective of promoting transparency because it “provided a
    18
    thorough, publicly available explanation” of the rate
    authorities, “the formula uses inputs from publicly available
    data and information,” and it would “maintain[] the underlying
    calculations on its public website, similar to existing practice.”
    Id. at 349. Additionally, the Commission concluded that “[a]ny
    additional administrative burden associated with the
    calculation is minimal and justified by the need to address
    underlying drivers of the existing system’s deficiencies.” Id.
    Establishing just and reasonable rates: In Order 5763,
    the Commission rejected as “largely overstated,” id. at 352, the
    Mailers’ concern that the new rate system would unjustly
    enrich the Postal Service. Giving the Postal Service greater
    rate authority was necessary, in the Commission’s view, to
    allow “the Postal Service to set rates that would not threaten its
    financial integrity.” Id. The new system would also protect
    mailers because it “limit[ed] the accrual and use of rate
    authority to correct particular systemic deficiencies.” Id. For
    instance, the Commission found that the density-based rate
    authority would not result in excessive rates because it does not
    constitute a rate reset, and its formula is designed to produce
    conservative cost estimates. Id. at 353–54. The Commission
    also found that the ratemaking system included “sufficient
    safeguards” to prevent excessive rate increases, pointing out
    that ratepayers may challenge rate changes before the
    Commission. Id. at 358–59.
    Despite the Mailers’ objections to the new ratemaking
    system, the Commission articulated a rational connection
    between the statutory objectives and the decision it made.
    Given the deference due to an agency’s judgment about how to
    balance competing factors, USAir, 
    969 F.2d at 1263,
     the
    Mailers offer no basis for the court to conclude that the
    Commission’s decision was arbitrary and capricious in meeting
    the statutory objectives.
    19
    2.
    The Mailers challenge the density-based rate authority as
    arbitrary and capricious, because (1) it fails to account for per-
    unit revenue and therefore will “grossly over-recover delivery
    costs,” and (2) it will accelerate, rather than remedy, the decline
    in mail density. The Mailers further maintain that the
    Commission failed to respond meaningfully to comments
    raising these objections. Mailers Br. 34–46.
    The Commission adequately justified its density-based
    rate authority. First, it was not arbitrary for the Commission to
    reject comments that the density-based rate authority had to
    account for the mix of delivered mail and per-unit revenues.
    As the Commission explained, the “rate authority is designed
    to offset increases in per-unit costs” caused by declining mail
    density, “not . . . to offset contribution changes from individual
    mail classes.” Order 5763 at 95. Per-unit revenues are
    irrelevant, according to the Commission, because “changes to
    per-unit costs are not isolated to specific classes.” 
    Id.
     Rather,
    “[a]s overall volume decreases,” the fixed costs associated with
    delivering the mail “are borne by fewer pieces, driving an
    increase in per-unit costs, irrespective of class.”            
    Id.
    Additionally, a revenue-based formula would tie the density
    authority to the Postal Service’s pricing decisions, leading to
    inefficient pricing. 
    Id.
    Nor did the Commission irrationally reject the Mailers’
    argument that the density-based rate authority would accelerate
    volume loss. Before the Commission, the Mailers argued that
    the supplemental rate authority would trigger a “death spiral,”
    a self-reinforcing cycle where price hikes induce further
    volume loss. Comments, Alliance of Nonprofit Mailers, at 28–
    39 (Feb. 3, 2020); Comments, Nat’l Postal Policy Council, 36–
    20
    38 (Feb. 3, 2020). The Commission, however, found that this
    argument rested on the faulty premise that market-dominant
    products are highly price sensitive. Order 5763 at 82. In its
    “experience, demand for Market Dominant products has been
    relatively price inelastic”: volumes “grew steadily” before
    2006 when prices were not capped yet consistently declined
    during the price-cap era. 
    Id.
     As a result, the Commission
    “expected” “the decrease in volume induced by the density-
    based rate authority . . . to be less in proportional terms than the
    amount of density-based rate authority.” 
    Id.
    The Mailers maintain that the Commission’s estimate of
    price sensitivity is too low, because it is calculated using data
    from a period when price changes were small relative to those
    anticipated with the new rule. Comments, Alliance of
    Nonprofit Mailers, at 31–32 (Feb. 3, 2020). But a disagreement
    over price sensitivity is insufficient to invalidate the
    Commission’s order, as this court defers to the Commission’s
    reasonable economic assumptions and predictions. See
    Newspapers Ass’n of Am., 734 F.3d at 1216; City of Los
    Angeles v. Dep’t of Transp., 
    165 F.3d 972
    , 977 (D.C. Cir.
    1999). Further, the Commission responded to the Mailers’
    objection by noting that the Postal Service did not have to use
    all available rate authority if doing so would be
    counterproductive. Order 5763 at 83. The Commission also
    noted that it “retains the authority to revisit the density-based
    rate authority” if “volume effects are outside the expected
    range.” 
    Id.
    And the Mailers object that the Commission ignored their
    comments that Order 5763 overestimated density-related costs
    relative to the “roll-forward” method used in other contexts.
    But the Commission found that using a prospective method like
    the roll-forward method “would be more complicated,” “entail
    more uncertainty,” and “require an additional mechanism in
    21
    later years to correct for inaccurate projections.” 
    Id. at 91
    .
    Given that “[n]one of the commenters ha[d] shown that a
    forward-looking model would have sufficiently improved
    accuracy over the Commission’s backwards-looking estimate,”
    the Commission concluded that they had failed “to justify these
    tradeoffs.” 
    Id. at 91 n.136
    .
    3.
    Lastly, the Mailers maintain that the Commission “ignored
    evidence demonstrating that density and other new rate
    authorities are not necessary” because “the pandemic has
    spurred massive volume increases in profitable packages,
    improving [the Postal Service’s] financial condition overall.”
    Mailers Br. 46–47.
    The Commission adequately supported its decision not to
    reopen the record. It found that the COVID-19 pandemic did
    not alter its finding that the existing ratemaking system failed
    to achieve the Accountability Act’s objectives because “[t]he
    Postal Service’s finances remain[ed] unstable” and “the
    problems identified in Order No. 4257 with respect to pricing
    and operational efficiency and unreasonable rates have not
    abated.” Order 5763 at 26–27. “These challenges,” the
    Commission observed, “which all pre-date the pandemic, are
    expected to persist as long as the existing ratemaking system
    remains in effect, and nothing specific to the pandemic alters
    [its] findings with regard to these deficiencies.” 
    Id. at 27
    . The
    Commission therefore “[did] not find any good cause to further
    delay implementation of the [new] ratemaking system,” and
    stated that it would “intervene as necessary if economic
    conditions prevent the final rules from operating as intended to
    achieve the objectives of section 3622.” 
    Id. at 31
    .
    22
    The Mailers further submit that the Commission relied on
    “stale data” from 2019, and that the Postal Service’s revenue
    and cash position meaningfully improved by mid-2020.
    Mailers Br. 48. But in Order 5763, the Commission noted that
    pricing authority should be determined not by revenue, but by
    costs, and that “as a result of the pandemic[,] there are fewer
    total mailpieces today over which the costs of servicing and
    maintaining the Postal Service’s network can be distributed.”
    Order 5763 at 28–29, 95. The mid-2020 financial data cited
    by the Mailers does not invalidate the Commission’s reasoning.
    Moreover, in response on appeal the Commission points out
    that the Postal Service’s financial condition worsened by the
    end of 2020, as indicated by operating losses comparable to
    those in previous years and declining profitability. P.R.C. Br.
    72 (citing its financial analysis and 10-K Statement, Fiscal
    Year 2020).
    III.
    The Postal Service also contends that Order 5763 was
    arbitrary and capricious, but advances arguments diametrically
    opposed to those of the Mailers.
    A.
    The Postal Service first maintains that the Commission’s
    new ratemaking system defies reasoned decision-making by
    “not actually provid[ing] [it] with an opportunity to cover its
    costs” and so “perpetuates the same faults that [the
    Commission] found in the legacy system.” USPS Br. 27.
    Analogizing its situation to that of a bicycle tire with a leak, the
    Postal Service argues that the Commission’s new system had
    not only to account for future revenue loss (i.e., patch the hole)
    but also return rates to a compensatory level (i.e., reinflate the
    tire). See 
    id. at 28
    –29. Because the new system does not reset
    23
    rates, the Postal Service posits that its financial stability
    remains insecure, making Order 5763 arbitrary and capricious
    “on its [o]wn [t]erms.” 
    Id. at 26
    –27, 30–31.
    In Order 5763, the Commission addressed the Postal
    Service’s argument that its proposed rate authorizations were
    inadequate to achieve financial stability because they did not
    reset rates to fully compensatory levels. Order 5763 at 347–
    48. The Commission explained that it “ha[d] never asserted
    that the Market Dominant ratemaking system must
    immediately recover all of the historic net losses or reset all
    rates to a level sufficient to cover all costs.” 
    Id. at 347
    . Such
    a system “would fail to balance” the competing objectives of
    rate stability and predictability and maximizing efficiency
    incentives because it would “incentivize the Postal Service to
    solely raise rates to respond to its challenges.” 
    Id.
     In contrast,
    the supplemental rate authorities balanced these objectives
    because they “mitigate the imminent financial pressure on the
    Postal Service, correct certain harmful pricing practices, and
    retain sufficient incentives to pursue cost reductions and
    efficiency gains.” 
    Id.
     Further, “[g]iven that the near-term
    financial instability is a source of imminent peril,” the
    Commission concluded that it was reasonable “to address those
    more time-sensitive issues first and then evaluate how the
    longer-term financial stability issues should be addressed, in
    conjunction with the other objectives, under the modified
    ratemaking system.” 
    Id. at 348
    .
    This explanation satisfies arbitrary-and-capricious review.
    The Accountability Act instructs that the nine objectives “shall
    be applied in conjunction with [each other].” 39 U.S.C.
    § 3622(b).    Following that directive, the Commission
    reasonably concluded that although a rate reset might further
    the goal of financial stability, it would undermine other
    objectives. It explained that allowing the Postal Service to
    24
    cover its costs solely through rate increases would discourage,
    not incentivize, cost-cutting and efficiency improvements.
    Order 5763 at 347. Further, a rate reset of the magnitude
    proposed by the Postal Service would “represent a regression”
    in progress toward achieving predictable and stable rates. Id.
    at 297. With these findings, it was not arbitrary for the
    Commission to choose a system that balanced the Act’s
    competing objectives rather than one that maximized financial
    stability at the expense of other goals. See U.S. Postal Serv.,
    963 F.3d at 141. Equally reasonable was the Commission’s
    decision to address the problem incrementally. It is well settled
    that agencies need not solve a problem in a single rulemaking.
    See Mobil Oil Expl. & Producing Se. Inc. v. United Distrib.
    Cos., 
    498 U.S. 211
    , 231 (1991).
    B.
    In a related challenge, the Postal Service maintains that the
    Commission failed to provide a reasoned explanation for
    deciding not to implement a rate reset. In its view, the
    Commission’s “suggest[ion] that a rate reset is unnecessary” is
    contrary to the evidence, which shows that a rate reset is needed
    to return the Postal Service to financial solvency, as well as the
    Commission’s own statements in Order 5763. USPS Br. 32–
    35. Further, the Postal Service maintains that the Commission
    inadequately explained its finding that a rate reset was contrary
    to some statutory objectives. 
    Id. at 36
    –43.
    The Postal Service’s objections are unavailing. To begin,
    the record does not support the Postal Service’s argument that
    the Commission suggested a rate reset is “unnecessary.” The
    materials cited by the Postal Service merely state that the
    Commission has decided to adopt rate authorities tailored to
    specific costs; the materials did not state or otherwise suggest
    that the new ratemaking system rendered a rate reset
    25
    unnecessary. Order 5337 at 60; Order 5763 at 173. Nor is the
    Commission’s decision inconsistent with the evidence or its
    prior statements.      Rather, the Commission reasonably
    determined that implementing a rate reset “at this time” would
    be contrary to various statutory objectives. Order 5763 at 347–
    48.
    Finally, the Postal Service’s challenge to the
    Commission’s weighing of the statutory objectives is
    unpersuasive. The Commission explained that resetting rates
    to equal costs would weaken the Postal Service’s incentive to
    cut costs and improve efficiency. 
    Id.
     On the other hand,
    enhancing the Postal Service’s rate authority so it can cover
    some of its costs through rate increases “narrow[s] the existing
    formidable gap between revenues and costs” thereby creating
    “meaningful” incentives to “bridge that gap fully via efficiency
    gains and cost reductions.” 
    Id. at 303
    . As for predictable and
    stable rates, the Commission explained that a sudden and
    significant price increase could harm mailers and mail volume.
    
    Id. at 196
    .      Regarding just and reasonable rates, the
    Commission explained that the new regulatory system
    “balance[d] . . . differing views” and “would neither threaten
    [the Postal Service’s] financial integrity nor would be
    excessive to mailers.” 
    Id. at 352
    –53. The Commission’s
    decision not to implement a rate reset at this time was thus
    reasonable and reasonably explained.
    Accordingly, the court denies the petitions for review.
