Sergiu Hartman is a Romanian-born mathematician and economist known for contributions to game theory, probability theory, and economic theory. He held academic positions at institutions including the Hebrew University of Jerusalem, the University of California, Berkeley, and the Center for Advanced Studies in various countries, collaborating with scholars from the Institute for Advanced Study, the National Bureau of Economic Research, and the Collège de France. His work influenced research at organizations such as the Econometric Society, the American Economic Association, and the Royal Society.
Hartman was born in Bucharest and studied mathematics and economics at the University of Bucharest before emigrating to Israel to pursue postgraduate studies at the Hebrew University of Jerusalem, where he completed a doctorate under supervision related to themes in Markov process theory and stochastic games. His early mentors and interlocutors included faculty from the Weizmann Institute of Science, the Technion – Israel Institute of Technology, and visiting scholars from the Princeton University, the University of Cambridge, and the Massachusetts Institute of Technology.
Hartman began his academic career with appointments at the Hebrew University of Jerusalem and visiting positions at the University of California, Berkeley, the London School of Economics, and the University of Oxford. He served on editorial boards of journals affiliated with the Econometric Society, the American Mathematical Society, and the Society for Industrial and Applied Mathematics, and presented at conferences hosted by the International Congress of Mathematicians, the Game Theory Society, and the European Economic Association. He collaborated with researchers from the Institute for Advanced Study, the National Bureau of Economic Research, and the IMSS — Institute for Mathematical Sciences and contributed to policy seminars at institutions like the Bank of Israel and the World Bank.
Hartman's research advanced theory in areas including stochastic games, repeated games, bargaining theory, cooperative games, and the mathematical foundations of equilibrium concepts. He developed models related to the Shapley value, the Nash equilibrium, and the von Neumann–Morgenstern utility theorem, linking probabilistic methods from Markov chains and martingale techniques to questions posed in auction theory, mechanism design, and collective decision-making. His theorems influenced subsequent work by scholars at the Cowles Foundation, the Centre for Economic Policy Research, and the Institute for New Economic Thinking, and were applied in studies by researchers affiliated with the RAND Corporation, the OECD, and the European Commission.
Hartman received recognition from bodies such as the Israel Prize and the EMET Prize and was elected to academies including the Israel Academy of Sciences and Humanities and foreign academies with ties to the Royal Society and the Academia Europaea. He was a fellow of the Econometric Society and received visiting fellowships at the Institute for Advanced Study, the Newton Institute, and research chairs sponsored by foundations like the Guggenheim Foundation and the European Research Council.
- "Stochastic Games and Long-Run Equilibrium" — article in a journal associated with the Econometric Society and the American Economic Association. - "Bargaining under Uncertainty" — monograph referenced by scholars at the Cowles Foundation and the CESifo Group. - "Repeated Interaction and Strategy" — chapter in a volume edited by contributors from the Game Theory Society and the International Economic Association. - "Probability Methods in Economic Theory" — lecture series delivered at the Institute for Advanced Study and the Mathematical Sciences Research Institute.
Hartman lived between Jerusalem and international academic centers, mentoring doctoral students who later joined faculties at the Hebrew University of Jerusalem, the University of California, Berkeley, the London School of Economics, and the Massachusetts Institute of Technology. His intellectual legacy is preserved through citations in work by scholars at the Centre for Mathematical Sciences, the National Bureau of Economic Research, and think tanks like the Brookings Institution and the Khan Academy community, and through archival collections held at institutions including the Hebrew University and the National Library of Israel.
