The OECD's structure consists of three main elements: • The OECD
member countries, each represented by a delegation led by an ambassador. Together, they form the OECD Council. Member countries act collectively through the council (and its standing committees) to provide direction and guidance to the work of the organisation. • The OECD substantive
committees, one for each work area of the OECD, plus their various subsidiary bodies. Committee members are typically subject-matter experts from member and non-member governments. The committees oversee all the work on each theme (publications, task forces, conferences, and so on). Committee members then relay the conclusions to their capitals. • The OECD
Secretariat, led by the Secretary-General (currently
Mathias Cormann), provides support to standing and substantive committees. It is organised into directorates, which include about .
Meetings Delegates from the member countries attend committee and other meetings. Former
Deputy Secretary-General estimated in 1997 that the cost borne by the member countries, such as sending their officials to OECD meetings and maintaining permanent delegations, is equivalent to the cost of running the secretariat. The OECD regularly holds minister-level meetings and forums as platforms for a discussion on a broad spectrum of thematic issues relevant to the OECD charter, member countries, and non-member countries. Noteworthy meetings include: • The yearly Ministerial Council Meeting, with the Ministers of Economy of all member countries and the candidates for enhanced engagement among the countries. • The annual OECD Forum, which brings together leaders from business, government, labour, civil society and international organisations. Held every year since June 2000, the OECD Forum takes the form of conferences and discussions, is open to public participation and is held in conjunction with the MCM. • Thematic Ministerial Meetings, held among ministers of a given domain (i.e., all Ministers of Labour, all Ministers of Environment, etc.). • The bi-annual World Forum on Statistics, Knowledge and Policies, which does not usually take place in the OECD. This series of meetings has the ambition to measure and foster progress in societies. • The Forum for Harmful Tax Practices • OECD Eurasia Week, which includes several high-level policy dialogue discussions to share best practices and experiences in addressing common development and economic challenges in Eurasia.
Secretariat Exchanges between OECD governments benefit from the information, analysis, and preparation of the OECD Secretariat. The secretariat collects data, monitors trends, and analyses and forecasts economic developments. Under the direction and guidance of member governments, it also researches social changes or evolving patterns in trade, environment, education, agriculture, technology, taxation and other areas. The secretariat is organised in directorates: • Centre for Entrepreneurship, SMEs, Regions and Cities •
Centre for Tax Policy and Administration • Development Co-operation Directorate • Directorate for Education and Skills • Directorate for Employment, Labour, and Social Affairs • Directorate for Financial and Enterprise Affairs • Directorate for Science, Technology, and Innovation • Economics Department • Environment Directorate • Public Governance Directorate • Statistics Directorate • Trade and Agriculture Directorate • General Secretariat • Executive Directorate • Directorate for Communications
Secretary-General The head of the OECD Secretariat and chair of the OECD Council is the Secretary-General. Secretary-General selections are made by
consensus, meaning all member states must agree on a candidate.
OECD Chief Economist British economist
Christopher Dow served as Chief Economist of the OECD from its establishment until 1973. In 1980, Canadian economist
Sylvia Ostry became the first woman to be appointed OECD Chief Economist, holding the position until 1983. In 1992,
Kumiharu Shigehara, former Chief Economist of the
Bank of Japan, became the first individual from outside the English-speaking world to be appointed OECD Chief Economist. At the time of his appointment, the
Financial Times, in an article entitled “Japan’s Turn” (22 January 1992), described him as exemplifying a new generation of Japanese figures characterised by self-confidence, strong international awareness, and a willingness to express their views openly. In February 2026, Italian Stefano Scarpetta was announced as the next Chief Economist. Scarpetta used to lead the Directorate's work on employment, migration and health.
Committees Representatives of member and observer countries meet in specialised committees on specific policy areas, such as economics, trade, science, employment, education, development assistance or financial markets. There are about 200 committees, working groups and expert groups. Committees discuss policies and review progress in the given policy area.
