This book seeks to explain long-term economic development and institutional change in terms of the cognitive features of human learning and communication processes. Martens links individual cognitive processes to macroeconomic growth theories, including economies of scale and scope, and to theories of institutional development based on asymmetric information in production processes and economies of scale in enforcement technology.With considerable flair, Bertin Martens has applied the hot new area of psychological and behavioural economics to notions of growth and development and has created a unique and impressive volume.
