Scholarship, consulting, and activism 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. According to the journalist Naomi Klein, Sachs said his plan could end Bolivian hyperinflation, which had reached up to 14,000%, in a single day. In his own account, Sachs describes the stabilization plan in The End of Poverty.Sachs, Jeffrey D. (2005). The End of Poverty. New York: Penguin. pp. 90–93. 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. He received an honorary doctorate from the Kraków University of Economics.
Russia After Poland's success, Sachs's advice was sought by Soviet president Mikhail Gorbachev and his successor, Russian president Boris Yeltsin, on the transition of the USSR/Russia to a market economy.
Sachs's methods for stabilizing economies became known as shock therapy and were similar to approaches used in West Germany after WW2. He faced criticism after the Russian economy underwent significant struggles after adopting the market-based shock therapy in the early 1990s.
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.
Sachs suggests that with improved seeds, irrigation and fertilizer, the crop yields in Africa and other places with subsistence farming can be increased from 1 ton per hectare to 3 to 5 tons per hectare. He said that increased harvests would significantly increase subsistence farmers' income, reducing poverty. Sachs does not believe that increased aid is the only solution. He also supports establishing credit and microloan programs, which are often lacking in impoverished areas.
In 2012 he was a founding co-editor, with John F. Helliwell and Richard Layard, of the World Happiness Report.
In 2005 Sachs and the philanthropist Ray Chambers co-founded the Millennium Promise Alliance, a nonprofit organization dedicated to ending extreme poverty and hunger; Sachs has served as its chief strategist. 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 Project's final report, Investing in Development, was presented in January 2005; Sachs later wrote that most of its key recommendations were adopted at the 2005 World Summit.
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.
During the Greek government-debt crisis in 2015, Sachs, Heiner Flassbeck, Thomas Piketty, Dani Rodrik, and Simon Wren-Lewis published an open letter to Chancellor of Germany Angela Merkel urging her to rethink her government's policy of austerity.
, he is 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.
In October 2013 Sachs and Laurence Tubiana launched the Deep Decarbonization Pathways Project, a joint initiative of the SDSN and the French think tank IDDRI.
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.
