This book provides the theoretical and analytical background necessary to understanding the process of growth and the implementation of economic policies. First, it presents the growth theory landscape and the evolution of growth as well as modern growth theory arguments where the policy implications of the theoretical approaches are set. The book then covers the relationship between policy and growth, discussing not only the growth prototypes that prevail but also their relation to politics and economic policy formation and decision making. In this context, policy formation determinants, as well as the targets, instruments, and policy implementations, are crucial. The role of structural changes and structural reforms and their relationship with economic growth is also analyzed. The book ends with an interdisciplinary study of how institutions and cultural background, entrepreneurship and innovation affect policy formation.
