Sachs has advised several countries on economic policy.
Bolivia Before the
1985 Bolivian general election,
Hugo Banzer asked Sachs to advise him on an anti-inflation plan to implement if he was elected. Sachs's stabilization plan centered on price deregulation, particularly for oil, along with cuts to the national budget. Sachs said his plan could end Bolivian
hyperinflation, which had reached up to 14,000%, in a single day. Banzer lost the election to
Víctor Paz Estenssoro, but Sachs's plan was still implemented. Inflation quickly stabilized in Bolivia. Hyperinflation reduced within weeks after the Bolivian government implemented his suggestions and the government settled its $3.3 billion debt to international lenders for about 11 cents on the dollar. At the time, this was about 85% of Bolivia's GDP.
Advising in post-soviet economies Poland In 1989, Sachs advised Poland's
anticommunist Solidarity movement and the government of Prime Minister
Tadeusz Mazowiecki. He wrote a comprehensive plan for the transition from
central planning to a
market economy that was incorporated into Poland's reform program, led by Finance Minister
Leszek Balcerowicz. Sachs was the main architect of Poland's debt reduction operation. He and IMF economist
David Lipton advised on the rapid conversion of all property and assets from public to private ownership. Closure of many uncompetitive factories ensued. In Poland, Sachs was firmly on the side of rapid transition to capitalism. At first, he proposed U.S.-style corporate structures, with professional managers answering to many shareholders and a large economic role for stock markets. That did not sit well with the Polish authorities, but he then proposed that large blocks of the shares of privatized companies be placed in the hands of private banks. As a result, there were economic shortages and inflation, but prices in Poland stabilized by 1991. In 1999, the government of Poland awarded Sachs one of its highest honors, the Commander's Cross of the
Order of Merit.
Work on global economic development Since his work in post-communist countries, Sachs has turned to global issues of
economic development,
poverty alleviation,
health and aid policy, and
environmental sustainability. He has written extensively on
climate change,
disease control, and
globalization. Since 1995, he has been engaged in efforts to alleviate
poverty in Africa. According to
New York Magazine, Sachs's ambitions are hard to overstate... "His ultimate goal is to change the world—to 'bend history', as he once said, quoting
Robert F. Kennedy", wrote
Nina Munk in
The Idealist, a biography of Sachs. By the early aughts, he had risen from wonky academic to celebrity public intellectual. According to Munk, people in Sachs's inner circle affectionately called him a "shit disturber", someone whose ego was offset by a selfless genius and a penchant for challenging orthodoxies. "There's a certain messianic quality about him",
George Soros, one of his patrons, told Munk. He is founding editor of the
World Happiness Report. Sachs is co-founder and chief strategist of
Millennium Promise Alliance, a nonprofit organization dedicated to ending
extreme poverty and hunger. From 2002 to 2006, he was director of the
United Nations Millennium Project's work on the MDGs. After the adoption of the Millennium Development Goals (MDGs) in 2000, Sachs chaired the WHO Commission on Macroeconomics and Health (2000–2001), which played a pivotal role in scaling up the financing of health care and disease control in the low-income countries to support MDGs 4, 5 and 6. He worked with UN Secretary-General
Kofi Annan in 2000–2001 to design and launch
The Global Fund to Fight AIDS, Tuberculosis and Malaria. He also worked with senior
George W. Bush administration officials to develop the PEPFAR program to fight
HIV/AIDS and the PMI to fight malaria. On Annan's behalf, from 2002 to 2006 he chaired the
UN Millennium Project, which was tasked with developing a concrete action plan to achieve the MDGs. The UN General Assembly adopted the UN Millennium Project's key recommendations at a special session in 2005. In 2010, he became a commissioner for the
Broadband Commission for Sustainable Development, whose stated aim is to boost the importance of
broadband internet in international policy. The
Millennium Villages Project (MVP), which he directs, operates in more than a dozen African countries and covers more than half a million people. Its critics have questioned both the project's design and claims made for its success. In 2012,
The Economist reviewed the project and concluded, "the evidence does not yet support the claim that the millennium villages project is making a decisive impact". Critics have said that the program did not include suitable controls to allow an accurate determination of whether its methods were responsible for any observed gains in economic development. A 2012
Lancet paper claiming a threefold increase in the rate of decline in childhood mortality was criticized for flawed methodology; the authors later admitted that the claim was "unwarranted and misleading". In her 2013 book
The Idealist: Jeffrey Sachs and the Quest to End Poverty, journalist
Nina Munk concluded that the MVP was a failure. From 2002 to 2018, Sachs was special adviser to the UN Secretary-General. Until 2016 he held a similar advisory position related to the
Millennium Development Goals (MDGs), eight internationally sanctioned objectives to reduce extreme poverty, hunger, and disease by 2015. In connection with the MDGs, he was appointed special adviser to the UN Secretary-General in 2002 during the term of
Kofi Annan, and later to
António Guterres. In his capacity as a special adviser at the UN, Sachs frequently met with foreign dignitaries and heads of state. He developed a friendship with
Bono and
Angelina Jolie, who traveled to Africa with him to witness the progress of the Millennium Villages. he was president of the UN
Sustainable Development Solutions Network. In June 2025, Sachs attended the
Forum of the Future 2050 in
Moscow, a conference organised by
Konstantin Malofeev. Sachs is one of the founders of the
Deep Decarbonization Pathways Project. Sachs is an SDG Advocate for Guterres on the
Sustainable Development Goals (SDGs), a set of 17 global goals adopted at a UN summit meeting in 2015. ==Honorary and other roles==
