Holding a Ph.D. in economics from the Australian National University, Ngo Van Long was a professor in the Department of Economics at McGill University and a CIRANO Fellow since 1994. Professor Long has made significant and lasting contributions in several distinct but related fields, emphasizing their complementarity and intersections: resource and environmental economics, international trade theory, dynamic optimization and dynamic game theory in economics, and industrial organization theory.

His research covers a wide range of issues in microeconomic theory with specialization in four separate but related fields of economics, stressing their complementarity and intersections: resources and environmental economics, theory of international trade, theory of dynamic optimization and dynamic games in economics, and theory of industrial organization. Since 1973, he has consistently published articles and books in these four fields, and where possible, emphasizing their complementarity.

Ngo Van Long has published articles in a wide range of journals, including Econometrica, the Quarterly Journal of Economics, the Journal of Economic Theory, the International Economic Review, the Economic Journal, Economic Theory, and field journals such as the Journal of Environmental Economics and Management, the Journal of International Economics, the Review of International Economics, Games and Economic Behavior, the Journal of Public Economics, the International Journal of Industrial Organization, the Journal of Economics and Management Strategy, the Journal of Economic Dynamics and Control, Dynamic Games and Applications, the Journal of Development Economics, and the Journal of Economic Behavior and Organization.
