The 2025 Sveriges Riksbank Prize in Economic Sciences was awarded to Joel Mokyr, Philippe Aghion, and Peter Howitt for their work on innovation-driven economic growth.
Joel Mokyr received one half of the prize for identifying the prerequisites for sustained growth through technological progress.
Philippe Aghion and Peter Howitt jointly received the other half for their theory of sustained growth through creative destruction.
Mokyr's research highlights the importance of both propositional knowledge and prescriptive knowledge for sustained growth.
Detailed Insights:
Mokyr's work emphasizes that sustained growth requires a continuous flow of useful knowledge, comprising both understanding why things work (propositional) and practical instructions (prescriptive).
Before the Industrial Revolution, innovators lacked a foundation of prescriptive knowledge, hindering the ability to build upon existing knowledge, which changed with the advent of precise measurement and reproducible experiments.
Aghion and Howitt's model of creative destruction illustrates how technological advancement drives growth but also displaces existing technologies and firms.
Their model helps analyze the optimal level of R&D investment by considering the benefits of replaced technologies to society and the potential for excessive profits from incremental innovations.
Mokyr's research suggests governments should invest in skilling and foster an environment open to change to facilitate sustained growth, as innovation inevitably creates both winners and losers.
Key Concepts Involved:
Propositional Knowledge: Understanding the natural world and the reasons behind how things function.
Prescriptive Knowledge: Practical instructions, recipes, or drawings that describe how something works.
Creative Destruction: The process where innovation leads to progress but also displaces existing technologies and companies.
R&D (Research and Development): Activities undertaken to improve existing products and procedures, or to create new products and procedures.
