This book presents selected papers of the Euro-Asian Symposium on Economic Theory, held by the Institute of Economics of the Ural Branch of the Russian Academy of Sciences (Ekaterinburg, Russia) on June 29-30, 2022. The conference aims to promote research and develop effective solutions to urgent challenges in economic theory in the context of stability and uncertainty. The main theme of the 2022 Conference is the "Viability of Economic Theories". The chaos of the modern world forces us to rethink many theoretical positions. Researchers are trying to overcome the contradictions between theory and empiricism through new models, mechanisms and approaches. The challenges of recent social change have led to an adjustment in the perception, interpretation, and use of many concepts, necessitating an updating of these terms. The problems and contradictions identified in the studies will help to reconcile theoretical approaches with practice. The volume covers topics suchas sustainable development issues, economic shocks in the history of economic thought, modern economic concepts of identity, theory of organizations under uncertainty, review of economic theories with the "Corona crisis," models of consumer behavior, business cycles, theory of investment, issues of economic growth and market equilibrium, impact of social factors on the sustainability of the economy, etc. Moveover, the volume presents new solutions for the synthesis of mainstream and political economy ideas. These topics will be of great interest to academics, researchers and practitioners.
