This is the first series to highlight research into the processes and impacts of the state building and economic development of developing countries in the non-Western World that have recently come to influence global economy and governance. It offers a broad and interactive forum for discussions about the challenges of these countries and the responses of other countries to their rise. The term 'emerging-economy state,' a part of the series title, or its shorthand 'emerging states,' is intended to promote dialogues between economists who have discussed policy problems faced by 'emerging-market economies' and scholars in political science and international relations who have discussed 'modern state formation.' Many emerging states are still in the middle-income status and not immune from the risk of falling into the middle-income trap. The manner of their external engagement is different from that of the high-income countries. Their rise has increased the uncertainty surrounding the world. To reduce the uncertainty, good understanding of their purpose of politics and state capacity as well as their economies and societies would be required. Although the emerging states are far from homogenous, viewing them as a type of countries would force us to understand better the similarity and differences among the emerging states and those between them and the high-income countries, which would in turn to help countries to ensure peace and prosperity. The series welcomes policy studies of empirical, historical, or theoretical nature from a micro, macro, or global point of view. It accepts, but does not call for, interdisciplinary studies. Instead, it aims to promote transdisciplinary dialogues among a variety of disciplines, including but not limited to area studies, economics, history, international relations, and political science. Relevant topics include emerging states' economic policies, social policies, and politics, their external engagement, ensuing policy reactions of other countries, ensuing social changes in different parts of the world, and cooperation between the emerging states and other countries to achieve the Sustainable Development Goals (SDGs). The series welcomes both monographs and edited volumes that are accessible to academics and interested general readers.
