Ricardo Reis

Ricardo A. M. R. Reis (born September 1, 1978) is a Portuguese economist and professor of economics at London School of Economics. Prior to that he was professor of economics at Columbia University where he became a full professor at the age of 29, one of the youngest ever in the history of the university. He is the editor of the Journal of Monetary Economics and sits on the Board of Editors of the American Economic Review and the Journal of Economic Literature. He is an academic advisor and visiting scholar at the Federal Reserve Bank of Minneapolis, the Federal Reserve Bank of New York, and the Federal Reserve Bank of Richmond.
Reis earned his Bachelor of Science (B.Sc.) degree from the London School of Economics in 1999, and his Doctor of Philosophy (Ph.D.) from Harvard University in 2004. He taught at Princeton University from 2004 to 2008 before moving to Columbia. In 2009, Reis was ranked the second most cited young economist in the world. In a 2013 ranking of young economists by Glenn Ellison, Reis was considered the top economist with a PhD between 1996 and 2004, ahead of Esther Duflo and Enrico Moretti.
Reis's primary area of research is macroeconomics. His main theoretical contribution is the sticky-information Phillips curve together with associated theories of inattention, models of sticky information, and endogenous disagreement. In particular, in a 2002 article published in the Quarterly Journal of Economics, Reis and Gregory Mankiw proposed an alternative to the widely used New Keynesian Phillips curve, based on the slow diffusion of information among the population of price setters. Their sticky-information Phillips curve displays three related properties that are more consistent with accepted views about the effects of monetary policy. First, disinflations are always contractionary (although announced disinflations are less contractionary than surprise ones). Second, monetary policy shocks have their maximum impact on inflation with a substantial delay. Third, the change in inflation is positively correlated with the level of economic activity. This article is Reis's most cited work: According to Google Scholar, it has been cited more than 2000 times, while the RePEc citation count ranks it as one of the 300 most cited articles in the field of economics.
Reis's work on monetary policy has included proposing measures of pure inflation, showing when a central bank can go insolvent and stating principles of central bank design. His work on fiscal policy has focused on targeted fiscal transfers. and the role of automatic stabilizers. He also participated on debates over the Euro crisis, proposing an explanation for the crisisand designing European Safe Bonds.
He writes for the Portuguese newspaper Jornal de Noticias and participates frequently in economic debates in Portugal.
