What do entrepreneurs do, and why does an economy need them? Eamonn Butler explains entrepreneurship as a process of discovering opportunities, testing ideas and developing new products and services. He examines its contribution to innovation, productivity and growth, alongside theories that seek to explain the entrepreneurial role. The book also discusses institutions and policies that encourage initiative and competition, and situations in which entrepreneurial effort pursues privileges instead of creating social value. Written for general readers, students and those interested in economic policy, it provides a conceptual introduction to entrepreneurship and its wider effects rather than a step-by-step manual for starting a business.
