The 2025 Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel honoured Joel Mokyr, Philippe Aghion, and Peter Howitt for their ground-breaking analyses of how technological progress drives long-term economic growth. Mokyr’s historical synthesis traces the origins of sustained growth to the interplay between science, technology, and culture during the Industrial Revolution. Aghion and Howitt’s formal growth theory places that process within a dynamic framework of creative destruction, where innovation continually upsets existing production structures. Together, they provide a coherent intellectual framework connecting technological progress origins, mechanisms, and future sustainability, an agenda relevant to modern economic policy.
Economic history reveals a significant break: for thousands of years, humanity experienced only sporadic innovation bursts of technological creativity that did not lead to lasting improvements in living standards. In England, between 1300 and 1680, GDP per capita stayed nearly unchanged despite advances like the printing press or Newtonian mechanics. In contrast, after 1800, the United Kingdom and the United States entered a period of sustained exponential growth. The core question, why economic progress became self-sustaining only in the modern era, is central in the laureates’ work, answered through their lifelong research.
Robert Solow’s growth accounting had already shown that physical and human capital alone could not explain long-run growth; the residual, “technical change,” did most of the work. Yet Solow’s model treated technology as exogenous. Paul Romer’s endogenous growth theory of the 1990s internalised the production of ideas but left unanswered how societies moved from technological stasis to sustained innovation. Mokyr, Aghion, and Howitt collectively bridge that gap. Mokyr identifies the historical conditions that launched the take-off, while Aghion and Howitt formalise how innovation remains self-renewing through market incentives and competition.
Joel Mokyr: Culture, Knowledge, and the Industrial Enlightenment
Mokyr’s research reorients the Industrial Revolution debate from material preconditions to intellectual dynamics. His central claim is that sustained growth emerged when propositional knowledge (understanding of natural regularities) and prescriptive knowledge (know-how in practical production) began reinforcing each other. The Enlightenment catalysed this feedback loop by institutionalising open science, empirical verification, and social tolerance for experimentation. Mokyr terms this the “Industrial Enlightenment”, a fusion of philosophy, engineering, and craftsmanship that transformed isolated inventions into cumulative technological progress.
Historically, previous civilisations had exhibited bursts of creativity, such as the Renaissance, the Dutch Golden Age, or China’s Song dynasty, but these lacked the self-reinforcing mechanisms to sustain growth. Mokyr’s comparative analysis shows that Europe’s take-off depended on scientific discovery and social structures that allowed new ideas to circulate freely, be tested in practice, and overcome resistance from vested interests. The British Industrial Revolution succeeded because Britain combined Enlightenment openness with a uniquely skilled artisan class, engineers, millwrights, and mechanics, capable of translating theory into application.
This synthesis challenges both purely economic and purely institutional explanations of industrialisation. Property rights and markets were necessary, but not sufficient; cultural beliefs about progress and curiosity also mattered. In Mokyr’s framework, sustained growth requires three mutually reinforcing pillars: (1) a joint evolution of science and technology, (2) mechanical competence that operationalises ideas, and (3) a society tolerant of creative destruction.
Mokyr’s perspective offers a cautionary note for modern economies. Growth depends on maintaining a virtuous cycle between knowledge generation and application. Policymakers cannot simply fund research or expand education; they must foster institutional arrangements that connect abstract discovery to practical implementation. Modern analogues of the 18th-century “Republic of Letters” include open-access research platforms, cross-disciplinary incubators, and innovation clusters that integrate universities, firms, and public agencies.
Aghion and Howitt: The Mechanics of Creative Destruction
If Mokyr explains how the flywheel of progress began turning, Aghion and Howitt explain how it keeps spinning. Their 1992 model of growth through creative destruction revolutionised growth theory by embedding Schumpeter’s insight into a tractable, micro-founded framework (A Model of Growth Through Creative Destruction). In their model, entrepreneurs engage in purposeful Research and Design to develop superior technologies that render existing products obsolete. Each innovation partially “steals business” from incumbents, generating temporary monopoly rents that reward risk-taking and destroy older rents. The economy settles into a balanced growth path at the aggregate level, sustained by the continuous turnover of firms and ideas.
Empirically, this process is visible in the pervasive dynamism of advanced economies. As the Committee Award Report notes, in the United States, more than 10% of firms enter or exit the market each year, and roughly a quarter of productivity growth stems from entry and exit alone. Industries with higher rates of firm turnover and job reallocation exhibit faster productivity growth. These micro-level disruptions reconcile the apparent contradiction between the smoothness of aggregate growth and the turbulence of the underlying innovation process.
Aghion and Howitt’s model also created a powerful bridge between macroeconomics and industrial organization. It formalises how competition policy, intellectual property rights, and education systems influence innovation incentives. The theory predicts a non-linear relationship between competition and innovation, the famous “inverted-U” effect. Too little competition allows monopolists to rest on their laurels; too much erodes rents and discourages risky innovation. Optimal policy thus lies in maintaining contestable markets that reward creativity without entrenching dominance.
The creative destruction framework has reshaped how economists think about industrial and innovation policy.
First, it highlights the importance of firm dynamics: growth depends less on the survival of incumbents than on the ease with which new entrants can challenge them. Barriers to entry, whether regulatory, financial, or digital, directly depress innovation. Policies that promote capital access, streamline business formation, and ensure competitive neutrality are thus central to sustaining growth.
Second, the model clarifies the role of state intervention. Governments should not pick winners but rather set the game’s rules to align private incentives with social welfare. For example, excessive patent length can slow cumulative innovation, while insufficient protection deters R&D investment. Evidence from Aghion and co-authors suggests that flexible intellectual property regimes, targeted R&D subsidies, and well-calibrated antitrust enforcement can maximize the social rate of innovation.
Third, the theory provides a framework for inclusive innovation. Creative destruction inevitably generates losers, displaced workers, obsolete firms, and disrupted regions. Aghion and Howitt’s extensions show that inequality can rise when innovation rents are concentrated among a few firms. The appropriate policy response is not to halt technological progress but to design labour market and education systems that equip workers to adapt. Lifelong learning, portable benefits, and active labour market policies become the social complements to innovation-led growth.
What do Mokyr, Aghion, and Howitt Mean for Policy?
The Mokyr, Aghion, and Howitt joint award synthesizes historical narrative and analytical theory. Mokyr’s long-run view explains why growth began; Aghion and Howitt’s models explain how it endures. Both perspectives converge on a central insight: sustained prosperity arises not from accumulation but from institutionalizing innovation as a continuous process. Three broad lessons emerge for policymakers.
(i) Protect the infrastructure of open knowledge. Mokyr’s historical evidence demonstrates that the Enlightenment’s success rested on freedom of inquiry and intellectual pluralism. Modern equivalents include academic independence, open data standards, and international scientific collaboration. Policies that politicise or restrict research, such as censorship, isolationism, or underfunding basic science, undermine the epistemic foundations of growth.
(ii) Foster adaptive institutions for creative destruction. Aghion and Howitt’s model underscores that economic dynamism depends on firms’ continuous entry and exit. This requires financial systems that can fund risky ventures, competition policies that prevent incumbents from entrenching market power, and legal frameworks that enable restructuring rather than protecting obsolescence. In practice, this means balancing the regulation of dominant technology platforms with preserving entrepreneurial experimentation.
(iii) Ensure social resilience to disruption. Mokyr’s historical case studies and Aghion–Howitt’s modern analytics reveal that resistance to innovation, whether through guilds or political backlash, can derail progress. The legitimacy of creative destruction ultimately depends on credible promises of inclusion and opportunity.
Many developing countries today face a dilemma similar to pre-industrial societies: technological diffusion occurs, but sustained innovation remains elusive.
Mokyr’s framework suggests that such economies need capital, education, and a cultural and institutional environment that values experimentation and tolerates failure.
Aghion and Howitt’s model implies that development strategies should prioritise dynamic entrepreneurship over static protectionism. Policies that stifle new entrants or privilege incumbents risk repeating historical patterns of stagnation. In essence, firms that may have created value in an earlier period but are unable to compete should be allowed to die. And this is a lesson that Kenya’s policymakers should heed. Commitment to legacy firms owned by the state or leading national champions has enormous opportunity costs.
