Assessing the global economic outlook is a fundamentally important task of international financial institutions, governments and central banks. In this paper we focus on the consequences of the rapid growth of emerging markets for monitoring and forecasting the global outlook. Our main results are that (i) the rise of the emerging countries has sharply altered the correlation of growth rates among the main economic areas; (ii) this is clearly detectable in forecasting equations as a structural break occurring in the 1990s; (iii) hence, inferences on global developments based solely on the industrialized countries are highly unreliable; (iv) the otherwise cumbersome task of monitoring many – and less studied – countries can be tackled by resorting to very simple bridge models (BM); (v) BM performance is in line with that of the most widely quoted predictions (WEO, Consensus) both before and during the recent crisis; (vi) for some emerging economies, BMs would have provided even better forecasts during the recent crisis.
