A CIRANO Researcher and Fellow since 2013, André Lemelin is Honorary Professor at the Urbanisation Culture Société Research Centre of the Institut national de la recherche scientifique (INRS).

Holding a Ph.D. in Economics from Harvard University, he is mainly interested in Computable General Equilibrium (CGCM) models.

He was Professor in the Department Economics at Université Laval (1978-1983), before joining the Urbanisation Culture Société Research Centre of the Institut national de la recherche scientifique (INRS).

He was co-head, with Bernard Decaluwé of Université Laval, of the design and development of a calculable general equilibrium model of Quebec for the Ministère des Finances du Québec, with the collaboration of the Institut de la statistique du Québec (2000-2005).

He is also a co-author of the CGE models of the PEP standard series and is a resource person in the Partnership for Economic Policy's Modeling and Policy Impact Analysis (MPIA) program.

He has also developed an expertise in the development of regional statistics: thus, in collaboration with the Institut de la statistique du Québec, he has devised a method that ISQ applies annually to estimate the GDP by industry of the administrative and metropolitan areas.

Based on his experience, he has since 2015 been developing a computable dynamic sequential general equilibrium model of the regions of Quebec (in partnership with Véronique Robichaud).

Finally, André Lemelin has published a manual of quantitative methods applied to urban and regional studies, in Spanish and French (e-book), the result of 14 years of teaching to students more focused on a qualitative approach to research.
