Inducement prizes – in which cash rewards are offered to motivate the attainment of specific targets – have long been used to stimulate scientific discovery and technology research and development. This volume presents an empirical investigation of the effect of these prizes on innovation. Presenting an in-depth study, Luciano Kay focuses on three recent cases of prize competitions in the aerospace industry: the Google Lunar X Prize, the Ansari X Prize and the Northrop Grumman Lunar Lander Challenge. Using a combination of real-time and historical analysis based on personal interviews, workplace visits and questionnaire and document data analysis, the author examines the particular dynamics of the prize phenomenon and offers a comprehensive discussion of the potential of prizes to induce innovation. This fascinating volume also sets out a systematic method to studying prize incentives, offering a concrete innovation model and case study design approach that will prove highly useful to further research efforts in the field.
