Trade, demand spillovers, and industrialization : the emerging global middle class in perspective.

Will the integration of BRIC (Brazil, Russia, India and China) into the global economy provide the biggest boost to the world economy since the industrial revolution ? In this paper, we investigate international demand spillovers brought about by an emerging global middle class and their impact on the international structure of production. We put forth a many-industry and two-country trade model featuring international competition, non-homothetic preferences and country-specific asymmetries in income distribution, productivity and population size. Its key characteristic is the introduction of demand complementarities propagating increasing returns across industries and national boundaries, which eventually translate into a global profit-multiplier.
