The seven largest emerging market economiesâ€”China, India, Brazil, Russia, Mexico, Indonesia, and Turkeyâ€”constituted more than oneâ€quarter of global output and more than half of global output growth during 2010â€“2015. These emerging markets, which we call EM7, are also closely integrated with other countries, especially with other emerging and frontier markets (FMs). Given their size and integration, growth in EM7 could have significant crossâ€border spillovers. We provide empirical estimates of these spillovers using a Bayesian vector autoregression model. We report three main results. First, spillovers from EM7 are sizeable: a 1 percentage point increase in EM7 growth is associated with an 0.9 percentage point increase in growth in other emerging and FMs and a 0.6 percentage point increase in world growth at the end of 3 years. Second, sizeable as they are, spillovers from EM7 are still smaller than those from G7 countries (group of seven of advanced economies). Specifically, growth in other emerging and FMs, and the global economy would increase by oneâ€half to three times more due to a similarly sized increase in G7 growth. Third, among the EM7, spillovers from China are the largest and permeate globally.
