2025 Nobel Prize in Economic Sciences Awarded

In News

What Happened

On October 13, 2025, the Nobel Memorial Prize in Economic Sciences was awarded to Joel Mokyr, Philippe Aghion, and Peter Howitt. Mokyr was recognized for identifying the historical and cultural prerequisites for sustained technological progress. Aghion and Howitt were jointly awarded for formalising the theory of sustained economic growth through 'creative destruction'.

Why It Matters

As the global economy faces massive disruptions from Artificial Intelligence and automation, their research provides a crucial roadmap. It proves that long-term prosperity comes not from protecting obsolete industries, but from embracing the destruction of old technologies while building strong institutions to support innovation and retrain workers.

Background

History & Context

For decades, macroeconomics relied on the Solow-Swan exogenous growth model (awarded the Nobel in 1987), which successfully explained capital accumulation but treated technological progress as an unexplained variable that simply 'fell from the sky'. In the 1980s, economists like Paul Romer (Nobel 2018) pioneered 'Endogenous Growth Theory', proving that innovation is driven by internal economic incentives. However, Romer's models generally assumed new inventions simply added to existing ones. In 1942, Joseph Schumpeter had theorised 'creative destruction'—the idea that new innovations inherently destroy old ones—but it remained an unquantifiable narrative. This changed in 1992 when Philippe Aghion and Peter Howitt published their landmark paper, 'A Model of Growth Through Creative Destruction', giving Schumpeter's theory rigorous mathematical form. Concurrently, economic historian Joel Mokyr published works like 'The Lever of Riches' (1990), meticulously proving why the Industrial Revolution triggered sustained growth in the West while earlier technological bursts in other societies stagnated.

What Changed

▶
Growth Modeling (Before vs. Now): BEFORE, the Solow-Swan model attributed long-term growth to unexplained, external technological shocks. NOW, the Aghion-Howitt 'Schumpeterian growth theory' mathematically proves that growth is endogenous, driven directly by profit-seeking entrepreneurs investing in R&D.
▶
Mechanism of Innovation: BEFORE, macroeconomic models (like Romer's 'expanding varieties' model) assumed new technologies peacefully coexisted with old ones. NOW, Aghion and Howitt's model incorporates 'creative destruction', quantifying how new technologies (e.g., streaming) render old ones (e.g., DVD rentals) entirely obsolete.
▶
View on Market Competition: BEFORE, perfect competition was viewed as the ultimate ideal, and monopolies were seen purely as market failures. NOW, Schumpeterian models show that the lure of temporary monopoly rents is the essential incentive for innovation, though permanent monopolies stifle the next wave of entrants.
▶
Understanding Historical Stagnation: BEFORE, historians struggled to explain why pre-18th-century societies experienced technological advances but no sustained economic growth. NOW, Mokyr's framework proves that growth requires a continuous feedback loop between 'propositional knowledge' (scientific theory) and 'prescriptive knowledge' (practical engineering).
▶
Economic Policy Focus: BEFORE, governments often prioritized protecting legacy industries and existing jobs to maintain economic stability. NOW, the accepted framework dictates that policy must protect the workers (via retraining and social safety nets) rather than the obsolete firms, allowing creative destruction to naturally occur.

What Did NOT Change

Despite proving the necessity of creative destruction, the laureates' work does not advocate for unregulated, cutthroat capitalism. The necessity of strong state institutions—to enforce competition policy, protect intellectual property rights, fund basic scientific research, and prevent successful innovators from blocking future entrants—remains as crucial as ever for translating technological change into broad prosperity.

Prelims Angle

NCERT Connection

This event directly challenges concepts in Class 12 Macroeconomics, Chapter 2 (National Income Accounting). The chapter teaches how to measure Gross Domestic Product (GDP) using the product, expenditure, and income methods. However, the 2025 Nobel laureates' work highlights a critical flaw in traditional National Income Accounting: GDP was designed for an industrial economy producing standardized goods (like wheat or steel), making it easy to measure 'process innovation' (making the same things cheaper). Because Schumpeterian growth is heavily driven by 'product innovation'—creating entirely new or vastly improved goods that render old ones obsolete—traditional GDP metrics often result in 'missing growth' and fail to accurately capture true technological progress.

Common Misconceptions

✗ Economic growth is primarily achieved by maximizing capital accumulation and maintaining perfectly competitive markets at all times.

✓ Temporary monopoly power (and the resulting abnormal profits) is a necessary incentive. Without the promise of these temporary 'rents', firms would not invest in risky Research & Development.

Basic microeconomics teaches that perfect competition is the ideal market structure for maximizing consumer surplus, often ignoring the dynamic, long-term incentives required to fund innovation.

✗ Endogenous growth theory was entirely created by Aghion and Howitt in the 1990s.

✓ Endogenous growth was pioneered by Paul Romer and Robert Lucas in the 1980s. Aghion and Howitt specifically contributed the 'Schumpeterian' branch, which added the element of 'destruction' to Romer's earlier models.

The broad umbrella term 'endogenous growth' is often conflated with its specific sub-theories, masking the distinct, Nobel-winning contribution of formalizing creative destruction.

Practice Questions

Q1

How Many Correct

Consider the following statements regarding theories of economic growth: 1. The Solow-Swan model treats technological progress as an endogenous variable driven by profit-seeking R&D investments. 2. According to Joel Mokyr, sustained economic growth requires a continuous feedback loop between propositional knowledge (science) and prescriptive knowledge (engineering). 3. The Aghion-Howitt model diverges from Paul Romer's earlier endogenous growth models by explicitly incorporating the obsolescence of existing technologies. How many of the statements given above are correct?

Q2

Match the Following

Match the Economic Model/Concept (List I) with its Core Characteristic (List II): List I: A. Solow-Swan Model B. Romer's Expanding Varieties Model C. Aghion-Howitt Model D. Mokyr's Framework List II: 1. Innovation continuously renders previous technologies obsolete 2. Long-term growth is driven by exogenous, unexplained technological change 3.

Q3

Assertion & Reason

Assertion (A): According to Schumpeterian growth theory, government policies that strictly prevent any firm from acquiring even temporary monopoly power will maximize long-term economic growth. Reason (R): The process of creative destruction relies on the lure of temporary monopoly rents to incentivize entrepreneurs to invest heavily in research and development. Select the correct answer:
