These proceedings constitute a selection of best papers from the 3rd International Conference on Economics and Social Sciences, Innovative Models to Revive the Global Economy, ICESS 2020, held in Bucharest, Romania, in October 2020. This book is a collection of research findings and perspectives related to recent economic challenges determined by the global crisis due to COVID 19, led by the set of improvements and changes in the economic, societal, and technological structures and processes towards the effort of reaching the sustainability goals.  During a crisis, countries, and businesses must respond promptly to ensure survival. They need to rethink social contracts, redefine work and consumption, mobilize resources at speed and scale, and at the same time rethink patterns from global to local. The innovative models presented in this book aim to ensure simultaneous economic development, social development, and environmental protection, to achieve a higher quality of life for all people, and protect all living beings and the planet.
