OECD

The OECD grew out of the postwar European cooperation system and began work in 1961 as the successor to the Organisation for European Economic Co-operation. Its founding convention gives it a broad purpose: promoting policies that improve economic prosperity, employment, living standards, and financial stability while supporting sustainable development and international trade.² The organisation is headquartered in Paris and is open to countries able to meet its standards and commitments; membership has expanded well beyond its original Western European and North American base.⁵

The OECD is not a supranational government. It does not generally impose domestic laws, and its analysis is intended to inform national decision-making through evidence, comparison, peer review, and agreed instruments.

The OECD is governed by a Council composed of representatives of each member country, with the European Union participating in its work. The Council sets strategic priorities and adopts decisions, recommendations, and other legal instruments; substantive work is prepared through committees in which national officials and specialists compare policies and negotiate common approaches.³

The Secretariat, led by the Secretary-General, supplies research, statistics, forecasts, and administrative support. Much of the organisation's influence comes from recurring peer review: governments examine one another's performance against shared indicators and policy principles. OECD decisions can be legally binding for participating countries in particular areas, while recommendations and declarations usually depend on political commitment rather than direct enforcement.⁴

The OECD's policy work spans taxation, education, labour markets, health, trade, competition, public governance, agriculture, development, digital policy, and the environment. Its economic outlooks and national surveys are widely used by ministries, central banks, researchers, and journalists, while databases such as PISA enable cross-country comparisons of student performance and education systems.¹

Some initiatives have had effects beyond the organisation's membership. The OECD has developed international tax standards, including work on base erosion and profit shifting, and has promoted transparency and exchange of tax information among jurisdictions.⁶ Its indicators can shape political debate, but comparisons require care: definitions, data quality, institutional arrangements, and national circumstances are not always identical. The organisation therefore combines quantitative measures with country-specific reviews and consultation.

The OECD's less visible role is its production of shared administrative standards and technical classifications, which help governments make their data and procedures comparable. Its legal instruments cover fields including chemicals, corporate governance, responsible business conduct, and international taxation, creating common expectations even where no treaty directly governs domestic policy.⁴

The organisation also works extensively with non-members through regional programmes, accession reviews, country partnerships, and global forums. This makes the OECD both a membership organisation and a hub for wider policy coordination.⁵ Its statistics are not neutral substitutes for political judgment: choices about what to measure, how to classify economies, and which outcomes to compare can affect the conclusions drawn from them. That tension between technical expertise and democratic accountability is a recurring feature of the OECD's public role.
