Gabriel’s current work is in the area of Real Business Cycles (RBC). Many aspects of macroeconomics abound with so-called puzzles: relationships that economic theory, and sometimes common sense, dictate, but that are not upheld in empirical studies. The apparent direct implication of these findings is that markets are not efficient, agents are not rational and that investors, including professional and institutional investors, routinely turn down enormous profit opportunities for no discernable reason. Having recently discovered, in a joint work with Karim Abadir, that a heretofore-unknown process dominates the dynamic behaviour of many macroeconomic variables, he is currently involved in showing that most of these so-called puzzles evaporate once the implication of the dynamics of this new process is properly taken into account. Indeed, their applied work shows that this nonlinear process effectively masks the true nature of the relationship between macroeconomic variables to the current econometric methods.
He is currently interested in developing new methods that deal effectively with the problem of persistence and nonlinear dynamics in macroeconomics; investigating the phenomenon that is responsible for generating this nonlinear dynamics; analysing the economic policy issues and implications of this dynamic, such as the persistence of monetary policy and of inflation; and extending the analysis to the financial market (to explain the dynamics of the stock market), labour market (to understand the persistence of unemployment) and other areas of economics.
Gabriel joined the Department in September 2006. He previously held positions at the Universities of York and the State University of New York at Albany (USA), and visiting positions at the European Central Bank, Nuffield College, the Banco de Portugal, the University of British Columbia (Canada), the New Economic School (Russia), the Universidad Nova de Lisboã (Portugal) and Columbia Business School (USA). He is currently co-editor of the Bulletin of Economic Research. He holds degrees from Université Pierre & Marie Curie (Paris), the Ecole Nationale de la Statistique et de l' Administration Economique (Paris), Université Pantheon-La Sorbonne (Paris), and Columbia University (USA). He was Professor of Macroeconomics at the University of York from 2002-2006.
