International Institutions
International institutions are where the rules that constrain national policy are written. The single most important venue for wealth and power concentration policy is the OECD/G20 Inclusive Framework on BEPS (Base Erosion and Profit Shifting), which has produced the Two-Pillar agreement (see Global Tax Coordination) and the Common Reporting Standard. The OECD’s Centre for Tax Policy and Administration drafts the technical standards that 147 members then implement.
The institutional landscape is shifting. The UN Framework Convention on International Tax Cooperation process, launched in 2023 and ongoing through 2026–27, is a serious attempt to relocate rule-writing from the OECD (which is dominated by high-income countries) to the UN (where lower-income countries have proportionally more voice). Outcomes will shape whether the next decade of international tax rules accommodate or resist a billionaire minimum tax and stronger anti-abuse rules.
The IMF and World Bank have shifted markedly on inequality since the mid-2010s, with the IMF’s Fiscal Affairs Department publishing increasingly progressive analyses and the World Bank’s Poverty and Shared Prosperity reports tracking distributional outcomes. The ILO anchors international labor standards. UNCTAD champions developing-country positions on trade, finance, and tax. Regional bodies — European Commission (DG TAXUD, DG COMP, DG EMPL), African Tax Administration Forum (ATAF), CIAT (Latin America) — implement and adapt these rules.

OECD/G20 Inclusive Framework: governance, decision rules, and stakes
Section titled “OECD/G20 Inclusive Framework: governance, decision rules, and stakes”The OECD/G20 Inclusive Framework on BEPS (Base Erosion and Profit Shifting) is the operational venue where the most consequential international tax rules are written. As of late 2025, 147 members participate (38 OECD members and 109 non-OECD members), up from 82 at its inaugural Kyoto meeting in June 2016. The Framework operates through:
- Plenary meetings (twice annually) where representative-level decisions are made on agenda items.
- Working Parties (issue-specific technical groups) that develop the substantive proposals.
- The OECD CTPA Secretariat (Centre for Tax Policy and Administration), which provides analytical and drafting support.
- G20 endorsements at the Finance Ministers and Leaders levels, which provide the political authorization for major rule changes.
Decision rules are largely consensus-based in the Framework, which has both strengths and weaknesses. Strengths: outputs adopted through consensus carry strong implementation legitimacy. Weaknesses: a single major signatory can block or substantially water down proposals (the U.S. has done this repeatedly on Pillar One; some smaller jurisdictions have done it on minor issues). The combination of broad participation and consensus decision-rules produces slow but durable progress.
The institutional stakes are substantial. The Framework currently writes the rules that determine where ~$30 trillion in global corporate income is taxed and how. Pillar Two has restructured corporate taxation across more than 60 enacted jurisdictions; the Common Reporting Standard (CRS) has reshaped financial-account information exchange across 124 jurisdictions; the BEPS Actions 1–15 produced the architecture for transfer pricing, treaty abuse, and intangible-asset taxation that governs most of the modern international tax system.
The U.S. role has been historically central but is currently contested. The Inclusive Framework was originally championed by the U.S. (under Obama-era Treasury leadership) as the alternative to less-controlled rule-writing at the UN. The December 2025 “Side-by-Side” package agreed by all 147 Inclusive Framework members charts a path forward for coordinated Pillar Two operation that accommodates the U.S. GILTI regime — acknowledging a partial U.S. carve-out for two of the three Pillar Two taxes — while preserving the framework’s core. Whether this accommodation is a durable compromise or the beginning of permanent fragmentation is the major outstanding question.
The UN Tax Convention process
Section titled “The UN Tax Convention process”The UN Framework Convention on International Tax Cooperation (UNFCITC) process — covered in detail in Global Tax Coordination — represents the most substantial institutional challenge to OECD primacy in international tax in 50 years.
Key process elements:
- Negotiating venue: UN headquarters in New York, with the Third Session held in Nairobi (November 2025) and subsequent sessions rotating.
- Decision rule: UN majority, not consensus. This is the central institutional difference from the OECD process.
- Voting blocs: African Group (continental coordination); G77+China (developing-country bloc); EU (often as bloc); OECD member states (often divided).
- Timeline: 2025–2027 for the framework convention text, alongside two early protocols — on cross-border services taxation and dispute prevention/resolution — currently under negotiation.
- Session schedule: Sessions 1–2 (August 2025, New York); Session 3 (November 2025, Nairobi); Session 4 (February 2026, New York) — concluded with member states advancing toward a consolidated “zero draft” of the convention text, with the two protocols still under active negotiation.
The political stakes are about who writes the rules. The OECD process is dominated by capital-exporting high-income countries. The UN process gives proportionally more voice to capital-importing developing countries — which produces different priority orderings (more emphasis on source-country taxing rights; more emphasis on Global South capacity-building; less emphasis on capital-mobility protection).
The two processes are not formally in opposition — they could in principle coexist as venues for different types of issues. In practice, however, they compete for the limited bandwidth of national tax administrations and finance ministries. The honest reading is that the Inclusive Framework’s effectiveness in 2025–2030 will partly determine whether the UN process becomes the primary venue for the next generation of reforms or remains a complementary track.
IMF and World Bank: the shift on inequality since 2014
Section titled “IMF and World Bank: the shift on inequality since 2014”The IMF and World Bank were both substantial intellectual contributors to the post-1980 deregulation/liberalization consensus that this wiki broadly argues against. Their positions began shifting noticeably around 2014 — driven by the post-2008 crisis, by accumulating evidence that the deregulation consensus was not delivering inclusive growth, and by leadership changes at both institutions.
IMF Fiscal Affairs Department (Vitor Gaspar’s directorship 2014–2024) produced a sustained series of analytical outputs documenting the inequality-growth relationship, the case for progressive taxation, the costs of unequal labor-market institutions, and the productivity benefits of broader-based economic participation. Key publications:
- Jaumotte & Buitron 2015 on labor-market institutions and inequality (covered in Labor Power).
- Fiscal Monitor annual reports incorporating distributional analysis from 2014 onward.
- IMF Article IV consultations increasingly include inequality and tax-policy assessments.
The shift is real and substantive but not complete. The IMF’s program lending in middle-income countries continues to include conditionality that can undermine the inequality agenda (austerity requirements that fall disproportionately on labor; structural-adjustment provisions that constrain progressive taxation). The internal struggle between the analytical and operational sides of the Fund is ongoing.
World Bank Poverty and Equity Global Practice has produced the Poverty and Shared Prosperity report series (biennial since 2016) tracking distributional outcomes alongside aggregate growth. The Bank’s lending portfolio has incorporated more explicit inequality framing (the Bank’s Strategic Framework references inclusive growth alongside aggregate growth as a top-line goal). Like the IMF, however, the operational lending portfolio still includes substantial activities that are inequality-orthogonal or inequality-worsening.
The honest summary is that both institutions are useful but constrained partners for the agenda in this wiki. They can be enrolled for technical assistance, analytical work, and convening — but they remain governed by member-state shareholders whose collective politics constrain how aggressively they can advance the agenda.
Regional institutions and implementation
Section titled “Regional institutions and implementation”Below the global level, several regional institutions play important roles in implementation and adaptation.
| Institution | Region | Role |
|---|---|---|
| European Commission DG TAXUD | EU 27 | EU tax-policy proposal and enforcement |
| European Commission DG COMP | EU 27 | EU competition/antitrust enforcement |
| European Commission DG EMPL | EU 27 | EU labor and employment policy |
| African Tax Administration Forum (ATAF) | African Union members | Continental coordination on tax administration; UN process leadership |
| Inter-American Center of Tax Administrations (CIAT) | Latin America | Regional tax cooperation; technical assistance |
| Asian Development Bank | Asia | Regional development lending; some inequality work |
| African Development Bank | Africa | Continental development lending; some tax-capacity work |
| Bank for International Settlements (BIS) | Global central banks | Banking regulation coordination |
| Financial Stability Board (FSB) | G20 + invited | Post-crisis financial-stability coordination |
| Eurasian Economic Union | Russia + 4 others | Regional economic integration |

The EU is by far the most institutionally developed regional architecture for the inequality agenda. DG TAXUD is the operational center for EU tax policy (Pillar Two transposition, ATAD updates, the wealth-tax discussion). DG COMP is the operational center for EU competition policy (Digital Markets Act enforcement, merger review, state-aid cases). DG EMPL coordinates labor policy (the Adequate Minimum Wages Directive, sectoral bargaining promotion).
ATAF and CIAT are smaller in operational footprint but increasingly important politically because they coordinate Global South positions in the OECD and UN processes. ATAF in particular was central to building the African Group coalition that drove the UN Tax Convention establishment. Founded in Kampala in November 2009, ATAF now has 43 African member countries and led the coordination of the African Group’s positions in both the OECD Inclusive Framework and the UN tax convention INC negotiations.
The “rule taker vs. rule maker” divide
Section titled “The “rule taker vs. rule maker” divide”The structural cleavage in international economic governance is between rule-makers (a small number of capital-exporting high-income countries that write the rules at OECD-style venues) and rule-takers (a much larger number of capital-importing countries that implement those rules domestically).
The post-2020 institutional shifts — the UN Tax Convention process, the African Group’s increased coordination, the BRICS expansion, the Brazilian and South African G20 presidencies pushing the billionaire-minimum-tax agenda — are all expressions of rule-takers attempting to become co-rule-makers. The success of these shifts depends partly on the structural arithmetic (rule-takers vastly outnumber rule-makers in any UN-style venue), partly on the coalitional cohesion of Global South positions (which has been historically variable), and partly on the responsiveness of existing rule-makers to the legitimacy challenge.
The strategic implication for the agenda in this wiki is that investing in Global South coordination capacity (ATAF, CIAT, regional research and policy institutes, technical-assistance programs) is high-leverage even when the immediate substantive payoffs are modest. The institutional infrastructure being built now will determine whether the next generation of international rules is written at venues that can address concentrated wealth at the global level.
