With the growing importance of the emerging economies (EEs) in the international scene, a lively debate has begun on whether the national economic cycles are converging or the cycles of EEs and advanced economies (AEs) are becoming disconnected, the so‐called ‘hypothesis of decoupling of EEs from the AEs’. Given the important practical implications that decoupling could have, for example, on the definition of national and international economic policies and on business strategies aimed at investment diversification and risk management, the question kindles not only the interest of academics but also policymakers and practitioners are very interested in the issue. The decoupling question has been long debated in different circles and from different points of view. This survey aims to retrace the steps of this debate and to provide some suggestions for future empirical researches.
