Book excerpt: This book examines smart cities through the lens of the information and communication technology (ICT)-driven transformation of the economy and economic systems and the resulting changes influencing organizations (public, private, and voluntary) and citizens in the smart city. In this context, the chapters included in this book address very specific questions pertaining to modes and models of economic collaboration, interest aggregation, and determinants of sustainable growth and development in the smart city. To this end, the circular economy, the sharing economy, the platform economy, and open innovation in the smart city are discussed. The notions of economic performance, competition, and business model innovation (BMI) are elaborated in detail. Finally, the question of the fragility of labor markets, including the availability of talent, is explored. By applying conceptually sound, inter- and multi-disciplinary approaches, frequently including case studies, this book provides a thorough insight into the complex question of how tools specific to the fields of economics, business management, innovation management, strategic management, entrepreneurship, and human resource management can be useful in view of understanding and harnessing the intrusion of ICT in the city space.
