Olivier Jean Blanchard (French:[blɑ̃ʃaʁ]; born 27 December 1948)[17][18] is a French economist and professor. He is Robert M. Solow Professor Emeritus of Economics at theMassachusetts Institute of Technology, Professor of Economics at theParis School of Economics, and as theC. Fred Bergsten Senior Fellow at thePeterson Institute for International Economics.[19]
Blanchard was born inAmiens (France). His father was a neurologist, his mother a psychiatrist. Blanchard says he was attracted to economics because of the student protests in France in 1968,[20] showing the importance of economics for society’s welfare, and the attractiveness of thinking about the issues through quantitative methods.[20] He obtained a DES in economics at theUniversity of Nanterre in 1972. He then moved from France to the United States in 1973. He obtained a PhD fromMIT in 1977, under the supervision ofStanley Fischer andRobert Solow. He was an assistant professor, then an associate professor atHarvard from 1977 to 1983, when he moved back to MIT. He became full professor in 1985, class of 1941 Professor from 1994 to 2010, and Robert Solow Professor of Economics from 2010 to 2020.[21] He has been Robert Solow Professor Emeritus since then. He was Chair of the economics department from 1998 to 2003. In 2008, he took a leave from MIT to be the Chief Economist of theInternational Monetary Fund, where he stayed until 2015.[22] In 2015, he became the Fred Bergsten Senior Fellow at thePeterson Institute for International Economics.[23] In 2023, he returned to France, joined theParis School of Economics, and remains a Senior Fellow of the Peterson Institute.[24]
Olivier has mentored a number of notable students throughout his academic career, includingJordi Galí,David Laibson,Tobias Adrian,Laurence M. Ball,Roland Bénabou,Ricardo J. Caballero, andPierre-Olivier Gourinchas, among many others.[18]
He is married to Noelle Blanchard, and has three daughters, Marie, Serena, and Julia.[17]
Blanchard is one of the leaders of “New Keynesian economics”, an approach tomacroeconomics that captures and extendsJohn Maynard Keynes’s general vision and gives a major role to movements in aggregate demand in economic fluctuations.[25] His research runs from theoretical research to empirical and policy relevant work. He is the author or editor of 30 books and more than 150 articles. According toIDEAS/RePEc, he is one of the most cited economists in the world.[26]
The development, withNobu Kiyotaki,[27] of micro foundations for the role of nominal price rigidities and the induced role of aggregate demand in a general equilibrium model withmonopolistic competition; this model has become the basis for later (and much more sophisticated) models with the same general approach. The derivation of the solution to linear models with rational expectations, with Charles Kahn.[28] The analysis of the co-movements between asset prices and economic activity under the assumption of rational expectations.[29] The identification of demand and supply shocks, withDanny Quah, through long-run restrictions in a VAR representation. The characterization of asset market bubbles under rational expectations, with Mark Watson.[30]
The “divine coincidence” result, derived in research withJordi Gali, that, in the baseline New Keynesian model, stabilizing inflation, which is good on its own, also leads output to be equal to its constrained optimum; this baseline result allows to think about the nature of the trade-off that emerges between inflation and output when other distortions are introduced. The effect of real wage rigidities on fluctuations and the role of monetary policy, with Jordi Gali.[31] The nature of thewage-price spiral, and the conditions under which it can emerge. The analysis of the US inflation episode of the 2020s, withBen Bernanke.[32] Blanchard has also argued for a higher inflation target for central banks, to decrease the risk of hitting the zero lower bound which dramatically decreases the scope for using monetary policy for stabilization purposes.
The characterization of the dynamic effects of spending and tax changes on both the level and the composition of output, with Roberto Perotti.[33] The effects of debt and deficits on output and welfare in a model in which people have finite horizons. The effects of debt and deficits in an economy where interest rates are low, potentially lower than the growth rate.[34] The way to think about and assess public debt sustainability, using stochastic debt sustainability analysis. Fiscal dominance of monetary policy, with an application to Brazil.[35]
Blanchard explored the “hysteresis” hypothesis, namely that transitory shocks may have a permanent effect on participation or unemployment, withLawrence Summers.[36] The channels through which this may happen include union wage setting with insiders and outsiders, and loss of skills or morale when unemployment is high. He additionally examined gross flows in labor markets, and the determination of equilibrium unemployment and vacancies, withPeter Diamond.[37] The theoretical foundations and the empirical evidence for the “aggregate matching function”, examining how hires depend on workers looking for jobs and jobs looking for workers.[38] The nature of theBeveridge curve, i.e. the relation between unemployment and vacancies, with Peter Diamond.[39] The mobility of workers across US states in response to demand shocks, withLarry Katz.[40] The set of optimal labor market institutions, from unemployment insurance to severance payments, withJean Tirole.[41]
Blanchard has argued that, between short run fluctuations and long run growth trends, there are important evolutions at the medium run frequency, reflecting major structural changes or distributional conflicts.[42] This could for example explain the evolution of the share of labor income from the 1970s. In the early 1990s, Blanchard became involved in transition from central planning to a market economy in Eastern Europe. In a book based on a series of lectures,[43] he discussed how to think about the various privatization options, and about the speed of transition. In an article withMichael Kremer, he argued that the large decrease in output at the start of the transition, despite the shift to a set of market prices, was due to “disorganization”, the failure of supply chains; the mechanism became relevant again in the face of supply chain disruptions during the covid and energy crisis inflation of the early 2020s.[44]
Blanchard wrote two surveys of the field, one in the 1990s and one in the 2000s, assessing what he saw as progress, and what he saw as dead ends.[45] After the2008 financial crisis, he organized a series of conferences on the lessons of the crisis, whether and how we should rethink macroeconomics and macroeconomic policy. MIT Press published those conclusions in a series of books, containing short articles by a wide set of important economists, and summaries by Blanchard and different co-editors.[46][47][48][49]
Blanchard joined the IMF as chief economist in September 2008, two weeks before theLehman collapse. His formal title was “Economic Counsellor and Head of the Research Department".[50]
He stayed until 2015, so that much of his time was spent analyzing the2008 financial crisis, and later theEuro area crisis. With the support, first ofDominique Strauss Kahn, then ofChristine Lagarde, he was given wide range to think about the issues raised by the two crises, and influence the position of the Fund on issues such as unconventional monetary policy, macro prudential policy, fiscal austerity, the pros and cons of capital flows, the effect of the crisis on emerging market countries. There were two episodes in particular where there was intense internal and external pushback.[22]
During his tenure as chief economist, Blanchard reshaped IMF policies. During theGreat Recession Blanchard supported global fiscal stimulus. During its slow recovery, he urged a cautious removal of stimulus and advocatedquantitative easing.[51]
In 2012, looking at output forecasts and realizations across advanced economies, Blanchard and Daniel Leigh found that the countries where fiscal consolidation was strongest were also those that underperformed relative to forecasts.[52][53][54] They concluded that the adverse effects of fiscal consolidation, the so called “multipliers”, were larger than those assumed by the IMF and theEU commission, and that fiscal adjustment should be slower. This led to a reassessment of IMF advice.[55][56][57]
Blanchard also argued that the IMF view that capital controls were bad should be revisited. In particular, he argued that short horizon capital flows were often costly, both when they came in and overwhelmed the domestic financial system, and when they suddenly went out. This led to a long discussion and a more nuanced position of the IMF stance on capital mobility.[58]
Under Blanchard's tenure at IMF,Jonathan D. Ostry and Andy Berg published their findings that "inequality was detrimental to sustained growth."[59][60] By April 2014, in theWorld Economic Outlook, Blanchard situated inequality as a "central issue" for "macroeconomic developments and one that the IMF should take into account".[60]
as the effects of the financial crisis slowly diminish, another trend may come to dominate the scene, namely rising inequality. Though inequality has always been perceived to be a central issue, until recently it was not seen as having major implications for macroeconomic developments. This belief is increasingly called into question. How inequality affects both the macroeconomy, and the design of macroeconomic policy, will likely be increasingly important items on our agenda for a long time to come.

In 1989, Blanchard and Stanley Fischer publishedLectures on Macroeconomics, a review of macroeconomic theory based on their joint graduate course in macroeconomics at MIT.[61][62] While not conceived as a graduate textbook, it quickly became one and has been widely used in graduate courses up to this day.[63]
Blanchard has also written an undergraduate textbook,Macroeconomics. The first edition was published in 1997. The ninth edition was published in 2024. The textbook has been translated and adapted in 21 foreign editions.[64]
Among the other books, Blanchard andHerbert Giersch (and other authors) co-wrote in 1985 “Employment and growth: A two-handed approach”, emphasizing the role of both supply and demand, and attempting to integrate the supply focused German approach and the more demand focusedAnglo-Saxon approach to macroeconomic policy.[65]
In 2019, at the request ofPresident Macron, Blanchard and Jean Tirole put together an international commission of experts to suggest policies aimed at fighting global warming, improving the retirement system, and improving redistribution. The report, “Les grands defis économiques” came out in 2021.[66][67][68]
Blanchard was Vice President of theAmerican Economic Association in 1995-1996, and President in 2018-2019.[69] He is a fellow of theEconometric Society and was a council member from 2001 to 2007. He is a member of theAmerican Academy of Sciences.[17] He was madea chevalier de la Legion d’honneur in 2008, and an officier in 2016. He is also acommander de l’ordre du mérite since 2021.[18] For 2024 he was awarded theBBVA Foundation Frontiers of Knowledge Award in the category of "Economics and Finance".[70]
He was a co-editor of theQuarterly Journal of Economics from 1979 to 1998, a founding editor of the American Economic Journal Macro from 2007 to 2009. He was a co-editor of the NBER Macroeconomics Annual from 1989 to 1993. He was a member of the advisory board of theCongressional Budget Office from 2016 to 2023, and a member of the Brookings Panel on Economic Activity from 1986 to 2023.[17][21]
