Jeffrey David Sachs (born November 5, 1954) is an American economist, academic, and public policy analyst who serves as a professor at Columbia University and director of its Center for Sustainable Development. Over a career spanning more than four decades, Sachs has occupied a distinctive position at the intersection of academic economics and international policy, serving as an adviser to governments across the globe and to three successive United Nations Secretaries-General. He first gained international prominence in the 1980s as one of the youngest tenured professors in the history of Harvard University, and subsequently became known for his advisory role in the economic transitions of Bolivia, Poland, and Russia during the late twentieth century. As president of the UN Sustainable Development Solutions Network, Sachs has been a central figure in global efforts to reduce extreme poverty, combat climate change, and promote the Sustainable Development Goals. His work has generated both acclaim and controversy, particularly regarding the outcomes of economic "shock therapy" programs in post-communist states, the effectiveness of the Millennium Villages Project, and, in more recent years, his public statements on the origins of COVID-19 and the war in Ukraine.

Early Life

Jeffrey David Sachs was born on November 5, 1954, in Oak Park, Michigan, a suburb of Detroit. He grew up in a middle-class Jewish family in the Detroit metropolitan area. Details regarding his parents and siblings remain largely outside publicly documented sources, though records indicate his family roots in Michigan.

Sachs showed early academic aptitude and progressed quickly through his education. He attended Harvard University as an undergraduate, where he immersed himself in economics. The intellectual environment at Harvard during the 1970s, shaped by faculty members engaged in both theoretical and applied economics, proved formative for Sachs, who would go on to pursue graduate work at the same institution without interruption.

Education

Sachs completed his entire higher education at Harvard University. He received his Bachelor of Arts degree in 1976, followed by a Master of Arts degree in 1978, and his PhD in economics in 1980. His doctoral dissertation was supervised by Martin Feldstein, a prominent macroeconomist who later served as president of the National Bureau of Economic Research. Sachs's training under Feldstein oriented him toward international macroeconomics and the study of fiscal and monetary policy in open economies, subjects that would define much of his subsequent career. Upon completing his doctorate at the age of 26, Sachs joined the Harvard economics faculty, and by 1983 he had received tenure, making him one of the youngest tenured professors in the university's history.

Career

Early Academic Career at Harvard

Sachs began his academic career at Harvard University in 1980 as an assistant professor of economics. His early research focused on international trade, macroeconomic policy, and the debt crises affecting developing countries during the 1980s. He quickly established a reputation as an energetic and prolific scholar. By 1983, he had achieved tenure, and by 1984 he was named a full professor, an unusually rapid ascent within the Harvard system.

During the 1980s, Sachs turned his attention to the sovereign debt crises in Latin America. His analysis of the economic conditions in Bolivia led to an invitation from the Bolivian government to serve as an economic adviser. In 1985, Sachs helped design Bolivia's economic stabilization program, which employed rapid liberalization measures and strict fiscal austerity to combat hyperinflation. The program succeeded in reducing Bolivia's inflation rate dramatically, and Sachs's involvement brought him to international attention as a practitioner of what became known as economic "shock therapy."

Advisory Work in Poland and Russia

Following the fall of the Berlin Wall in 1989, Sachs became involved in advising the transitional governments of Eastern and Central Europe. He served as an adviser to the Solidarity government in Poland, where he helped design the country's rapid economic transformation from a centrally planned economy to a market-based system. In a 1990 article in Foreign Affairs, Sachs and co-author David Lipton outlined the rationale for Poland's economic reform program, arguing that rapid and comprehensive reforms were preferable to gradualism in order to achieve macroeconomic stabilization and structural change. Poland's transition, while painful in the short term, is generally considered to have been among the more successful post-communist economic reforms in Eastern Europe.

Sachs subsequently advised the Russian government under President Boris Yeltsin in the early 1990s on its own transition to a market economy. The Russian reforms, which also employed elements of shock therapy including rapid privatization and price liberalization, proved far more contentious. Critics attributed significant social dislocation—including a sharp rise in poverty, a decline in life expectancy, and the concentration of wealth among a new class of oligarchs—in part to the speed and design of the reform program. Sachs later distanced himself from some aspects of the Russian reforms, arguing that the international community, particularly the United States and the International Monetary Fund, had failed to provide adequate financial support during the critical early phase of the transition.

Move to Columbia University

In 2002, Sachs left Harvard to join Columbia University, where he was appointed as the director of The Earth Institute, a research center focused on sustainable development, poverty reduction, and environmental stewardship. The appointment was a significant institutional move, as Columbia created a high-profile interdisciplinary platform for Sachs's work on global development. At Columbia, Sachs shifted the primary focus of his public work from macroeconomic reform in transitional economies to the eradication of extreme poverty and the promotion of sustainable development on a global scale.

He continued to serve at Columbia after The Earth Institute was restructured, becoming director of the Center for Sustainable Development within the university's School of International and Public Affairs. Sachs also holds an appointment at University College London's Institute for Innovation and Public Purpose.

United Nations Advisory Roles

Sachs has maintained a long association with the United Nations. In 2002, during the tenure of Secretary-General Kofi Annan, he was appointed as a special adviser on the Millennium Development Goals (MDGs), a set of eight internationally agreed objectives to reduce extreme poverty, hunger, and disease by 2015. From 2002 to 2006, Sachs directed the United Nations Millennium Project, which produced a comprehensive plan for achieving the MDGs.

From 2001 to 2018, Sachs served as a special adviser to the UN Secretary-General, a role that spanned the terms of Kofi Annan, Ban Ki-moon, and António Guterres. Following the adoption of the Sustainable Development Goals (SDGs) at the UN summit in 2015, Sachs was named an SDG Advocate for Secretary-General Guterres. In this capacity, he has promoted the 17 global goals and worked to mobilize political and financial support for their implementation.

As president of the UN Sustainable Development Solutions Network (SDSN), Sachs oversees a global initiative that mobilizes scientific and technical expertise for the implementation of the SDGs. He has also served, since 2010, as a commissioner for the Broadband Commission for Sustainable Development, which promotes broadband internet access as a tool for achieving development objectives.

Millennium Villages Project

One of Sachs's most prominent initiatives has been the Millennium Villages Project (MVP), which he co-founded through the Millennium Promise Alliance, a nonprofit organization dedicated to ending extreme poverty and hunger. Launched in 2005, the project established a network of village sites across sub-Saharan Africa to demonstrate that integrated, community-based interventions in health, education, agriculture, and infrastructure could accelerate progress toward the MDGs.

The MVP received significant funding and media attention, but it also became the subject of sustained scrutiny and debate. A 2005 Washington Post article examined the scale of Sachs's ambitions and the challenges of implementing large-scale development projects in rural Africa. A 2002 Harvard Magazine article also explored the broader debates around development economics and the challenges Sachs faced in translating academic theory into on-the-ground results. Critics raised questions about the project's cost-effectiveness, the rigor of its evaluation methodology, and whether its results could be sustained or replicated at larger scales. Supporters argued that the MVP demonstrated the feasibility of rapid improvements in health and agricultural outcomes in impoverished communities.

Climate Change and Environmental Advocacy

Sachs has been an active participant in international climate policy debates. He has argued for large-scale investment in renewable energy and for binding international agreements to reduce greenhouse gas emissions. In the lead-up to the 2015 Paris Agreement, Sachs contributed to public discourse on climate change, advocating for ambitious targets. A New York Times article in December 2015 discussed the broader context of international climate negotiations and the policy positions advanced by Sachs and others.

In 2015, Sachs was among a group of economists who signed an open letter to German Chancellor Angela Merkel published in the Tagesspiegel, calling for a reconsideration of European austerity policies and a greater focus on investment-led growth and sustainability.

Public Commentary on Geopolitics

In the 2020s, Sachs became an increasingly prominent public commentator on geopolitical affairs, speaking frequently on topics including the origins of COVID-19, United States foreign policy, and the Russian invasion of Ukraine. His views on these subjects have generated significant attention and criticism.

On the war in Ukraine, Sachs has argued that NATO expansion played a role in provoking the conflict and has called for diplomatic negotiations rather than continued military escalation. In a February 2025 analysis discussed in the Hungarian Conservative, Sachs outlined his view that the war could expand further—potentially to include Odessa—if a peace deal were not reached. In a transcript of a podcast appearance published by The Singju Post in February 2025, Sachs discussed what he characterized as a choice between "hegemony or peace" in Ukraine, arguing that U.S. policy had prioritized geopolitical dominance over diplomatic resolution.

Sachs has also spoken publicly about U.S. policy toward Iran. In February 2025, he co-authored an open letter published in In These Times addressed to the United Nations Security Council, opposing a potential U.S. military attack on Iran and arguing that Iran had not failed to negotiate in good faith. In a separate podcast appearance, Sachs discussed what he described as the strategic risks of a U.S. conflict with Iran.

These public positions have drawn criticism from commentators who have accused Sachs of amplifying narratives aligned with Russian or anti-Western perspectives, while supporters have defended his stance as consistent with a tradition of anti-interventionist foreign policy analysis.

Personal Life

Sachs is married to Sonia Ehrlich Sachs, a pediatrician who has been involved in global health work, including efforts associated with the Millennium Villages Project. The couple has three children. Sonia Sachs has served as health coordinator for the Millennium Villages Project and has worked on public health initiatives in sub-Saharan Africa. The family resides in New York City, where both have been affiliated with Columbia University.

Sachs's economic orientation has been described as Keynesian. He has authored or co-authored numerous books on economics and development, including The End of Poverty (2005), Common Wealth: Economics for a Crowded Planet (2008), and The Ages of Globalization (2020).

Recognition

Over the course of his career, Sachs has received numerous awards and honors from governments, universities, and international organizations. He has been named among Time magazine's "100 Most Influential People" and has received honorary degrees from multiple institutions worldwide.

His advisory work with the United Nations and his role in shaping international development policy, particularly through the Millennium Development Goals and the Sustainable Development Goals, have been recognized by various bodies. His academic contributions, including his early work on sovereign debt and macroeconomic stabilization, have been cited extensively in the economics literature.

Sachs has also received recognition for his work on climate change and environmental sustainability. His public advocacy and writing have reached broad audiences beyond academia, and his books have been translated into numerous languages.

Legacy

Jeffrey Sachs's career has spanned several distinct but interconnected areas of economics and public policy. His early advisory work on economic transitions in Bolivia, Poland, and Russia placed him at the center of some of the most consequential economic transformations of the late twentieth century. The debate over shock therapy and its outcomes, particularly in Russia, remains a defining aspect of his professional legacy and a subject of continued scholarly discussion.

His subsequent focus on global poverty, through the Millennium Development Goals, the Millennium Villages Project, and the Sustainable Development Goals, positioned him as one of the most visible advocates for international development in the early twenty-first century. The Millennium Villages Project, despite its controversies, contributed to ongoing debates about the most effective approaches to poverty reduction in sub-Saharan Africa.

In more recent years, Sachs's public commentary on geopolitics—including the war in Ukraine, U.S. foreign policy, and the origins of COVID-19—has expanded his public profile while also generating new controversies. His willingness to challenge prevailing Western policy positions has made him a polarizing figure in public discourse.

At Columbia University, Sachs continues to direct the Center for Sustainable Development and to lead the UN Sustainable Development Solutions Network, maintaining his role as a bridge between academic research and international policy.
