Innovation, entrepreneurship, knowledge, and human capital are widely acknowledged as key levers of development. Yet what are the sources of these factors, and why do they differ in their endowment across regions? Motivated by a belief that theories of economic development can move beyond the generally accepted explanations of location and the organization of industries and capital, this book establishes a behavioural theory of economic development illustrating that differences in human behaviour across cities and regions are a significant deep-rooted cause of uneven development. Fusing a range of concepts relating to culture, psychology, human agency, institutions, and power, it proposes that the long-term differentials in economic development between cities and regions, both within and across nations, is strongly connected to the underlying forms of behaviour enacted by humans on an individual and collective basis. Given a world of finite and limited resources, coupled with a rapidly growing population — especially in cities and urban regions — human behaviour, and the expectations and preferences upon which it is based, are central to understanding how notions of development may change in coming years. This book provides a novel theory of the role of psychocultural context and human behavioural and institutional frameworks in uneven economic development on a global scale.
