Core Insights - The 2025 Nobel Prize in Economic Sciences was awarded to economists Joel Mokyr, Philippe Aghion, and Peter Howitt for their contributions to understanding innovation-driven economic growth [1][2] - Mokyr received half of the prize for his work on the prerequisites for sustained growth through technological progress, while Aghion and Howitt shared the other half for their theory on sustained growth under creative destruction [1] Group 1: Mokyr's Contributions - Mokyr's research addresses why the Industrial Revolution occurred in 18th century Britain rather than in India, emphasizing the importance of "useful knowledge" accumulation, inclusive institutional environments, and cultural respect for experimental science [3][4] - His work highlights the role of platforms like the Royal Society in knowledge sharing, patent laws in protecting innovators, and societal attitudes towards science as critical factors for technological transformation into sustained productivity [3] Group 2: Aghion and Howitt's Theory - Aghion and Howitt's "creative destruction" model explains the dynamics of innovation, where competitive R&D leads to vertical innovation as the ultimate source of growth [7] - Their model illustrates that increased R&D activity can rapidly destroy existing innovations, thereby impacting current R&D incentives, and it provides a framework for understanding the transition from traditional fuel vehicles to electric vehicles [7][8] - The model also quantifies the effects of innovation on employment and industry structure, suggesting that while old industries may decline, the overall vitality of the economic ecosystem can improve [8] Group 3: Trends in Economic Research - Recent Nobel Prize selections reflect a shift in economic research from abstract theoretical modeling to addressing real-world issues, emphasizing dynamic processes over static analyses, and integrating interdisciplinary approaches [10] - This trend is particularly evident in new economic fields, where research must consider multiple dimensions such as technological feasibility, regulatory frameworks, and consumer behavior [10]
