The Nobel Prize in Economics 2025 was awarded to Joel Mokyr, Philippe Aghion and Peter Howitt for explaining how innovation drives economic growth. Mokyr received one half of the prize; Aghion and Howitt shared the other half. Their work helps answer a central question: why can improvements in knowledge and technology produce sustained increases in living standards?
The formal name is the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel. For exam purposes, the important point is not only the list of winners but also the difference between Mokyr’s historical explanation and Aghion and Howitt’s model of creative destruction.

Mokyr: why isolated inventions are not enough
An economy can experience an important invention without entering a long period of sustained growth. Mokyr’s work asks what allows useful knowledge to keep expanding and to be translated into practical improvements.
His explanation connects knowledge with technical competence and institutions that support progress. Knowing why a process works helps people improve it; practical skill helps turn that knowledge into usable machinery or methods. Institutions matter because learning and experimentation can be discouraged when established interests can suppress unfamiliar ideas.
This also clarifies why invention and diffusion are different. A discovery in one laboratory has a limited economic effect if firms cannot understand, adapt or apply it. Sustained growth requires repeated movement between new knowledge and practical production.
Creative destruction: the Aghion–Howitt mechanism
Creative destruction describes a process in which a new product or method makes an older one less competitive. The innovation creates value, but it can also reduce the income of firms and workers tied to the previous technology.
Consider an illustrative example. A manufacturer develops a process that makes a durable component with less material and energy. Buyers prefer the improved product, the innovator gains business and competing producers face pressure to adapt. Society may obtain more output from the same resources, even though the transition is disruptive for some existing producers.
The growth mechanism is a sequence, not a one-time event. Potential returns encourage research; successful innovation improves productivity; later innovators may displace the present leader. This places technological change inside the explanation of economic growth rather than treating it as an unexplained gift from outside the economy.
Productivity growth is different from simply adding inputs
An economy can expand output by adding workers, machines or working hours. Productivity growth means producing more or better output from a given combination of inputs. Innovation can improve production methods, management, product quality or the organisation of supply chains.
This distinction matters when judging development. A rise in investment is not proof that each unit of investment is becoming more productive. Likewise, a larger workforce does not automatically deliver sustained gains in income per person. Skills, useful technologies and effective production arrangements influence the result.
The policy tension: reward innovation without protecting incumbents forever
Innovation is uncertain and can require substantial investment before any commercial return appears. Some prospect of reward helps motivate that effort. Yet excessive protection for established firms can make it harder for new competitors to enter and improve on existing technologies.
The implication is a balance: support knowledge creation and the ability to commercialise it, while maintaining contestability. This is not a claim that every monopoly creates innovation or that every form of competition has identical effects in every industry.
- Research capacity: maintain the skills and institutions that generate useful knowledge.
- Entry and diffusion: enable capable new firms and help smaller businesses adopt appropriate technologies.
- Finance: assess how uncertain research differs from lending against an established asset.
- Transition support: help workers acquire new skills and move into viable employment as older activities decline.
What this means for India’s growth debate
Applied to India, this framework suggests evaluating innovation policy by what reaches production and improves outcomes. Patent counts, startup registrations and research spending describe parts of the system; none alone measures a durable productivity gain.
For example, a new agricultural technology has to work under local conditions and be usable by farmers before it raises their productivity. A digital system can reduce a firm’s costs only if employees can use it, its data are reliable and its processes are redesigned where necessary. These are applications of the framework, not specific conclusions attributed to the laureates about an Indian scheme.
Connect these concepts with the Indian economy notes and science and technology notes.
Frequently asked questions
1. Who won the 2025 economics prize?
Joel Mokyr, Philippe Aghion and Peter Howitt received it for their work on innovation-driven economic growth.
2. What does creative destruction mean?
New technologies or products create value while displacing older ones, producing both productivity gains and adjustment costs.
3. Did all three receive equal shares?
No. Mokyr received one half, while Aghion and Howitt shared the remaining half.
4. Does the research imply that growth is automatic?
No. Sustained progress depends on knowledge, capabilities, incentives and institutions that allow innovation and adaptation.
