  • How innovation drives economic growth

    Introduction

    The 2025 Sveriges Riksbank Prize in Economic Sciences was awarded to Joel Mokyr, Philippe Aghion, and Peter Howitt for “explaining innovation-driven economic growth.” Their research collectively answers one of the most fundamental economic puzzles — how nations sustain growth over centuries, not decades.

    Why in the News

    The Nobel Committee’s decision is significant because it celebrates innovation as the engine of sustained prosperity at a time when economies face stagnation despite technological abundance. It also marks a historical synthesis, combining Mokyr’s economic history with Aghion and Howitt’s modern growth models, to offer a unified vision of why the last two centuries broke free from millennia of stagnation. This award underscores that knowledge creation and openness to change are as critical to a nation’s future as natural resources or fiscal policy.

    Understanding the Foundations of Innovation-Driven Growth

    What did Joel Mokyr’s research reveal about sustained growth?

    1. Useful Knowledge: Mokyr argued that long-term growth depends on a constant flow of useful knowledge, divided into propositional (theoretical understanding) and prescriptive (practical implementation) forms.
    2. Before Industrial Revolution: Innovators understood why things worked (propositional) but lacked the technical ability to make them work (prescriptive).
    3. Scientific Revolution Impact: The 16th–17th centuries brought controlled experiments and reproducibility — transforming knowledge from abstract to applicable.
    4. Policy Implication: Nations must ensure technical education and skill development, as ideas alone cannot yield growth without implementation.

    How did Mokyr link innovation to social openness?

    1. Openness to Change: Innovation often disrupts existing systems and creates losers; societies resistant to change stifle progress.
    2. Historical Example: Britain’s sustained growth stemmed from skilled artisans and engineers who translated scientific ideas into industrial applications.
    3. Policy Lesson: Governments must create inclusive ecosystems that accept change, retrain workers, and redistribute gains from innovation.

    What is the Theory of Creative Destruction?

    1. Conceptual Core: Originally introduced by Schumpeter, “creative destruction” describes how innovation replaces older technologies and firms, creating both winners and losers.
    2. Aghion & Howitt’s Contribution: They formalized this process mathematically, showing how technological progress leads to sustained long-term growth.
    3. Dynamic Equilibrium: Innovation raises productivity but simultaneously displaces outdated industries — a perpetual cycle that fuels development.

    How much should a country invest in Research and Development (R&D)?

    1. Balancing Act: Aghion and Howitt’s model shows two opposing trends:
      1. Trend 1 — Underinvestment: Since society benefits from outdated technologies even after firms lose profits, R&D should be subsidized to ensure social spillovers.
      2. Trend 2 — Overinvestment: When incremental innovations capture disproportionate profits, R&D may be excessive and distort competition.
    2. Optimal Level: There is no universal ideal investment, but the model provides tools to identify an economy-specific optimum that maximizes welfare without creating monopolistic inefficiencies.

    Why does this Nobel matter for developing economies like India?

    1. Knowledge Ecosystem: The laureates’ findings emphasise that growth requires not just innovation, but translation — turning ideas into scalable realities through skills, entrepreneurship, and openness.
    2. India’s Imperative: Investments in R&D (currently ~0.7% of GDP), vocational skilling, and ease of doing business are crucial to realize the demographic dividend.
    3. Policy Relevance: The Economic Survey and NITI Aayog’s “Innovation Index” already underline similar principles — this Nobel reinforces India’s need to build a “knowledge economy.”

    Conclusion

    The 2025 Nobel Prize in Economic Sciences reaffirms that innovation, knowledge, and societal openness are the real engines of prosperity. Economic success is no longer a product of mere capital or labor, but of the synergy between imagination and execution. For India and other developing nations, the message is clear: sustained growth depends on nurturing human capital, research ecosystems, and tolerance for disruption. As Mokyr’s and Aghion–Howitt’s work shows, societies that embrace change, skill their people, and invest in ideas will lead the next chapter of human progress.

  • What are Climate Tipping Points?

    Why in the News?

    The Global Tipping Points Report (2025), authored by 160 scientists from 23 countries, warns that warm-water coral reefs have already crossed their thermal tipping point, triggering irreversible dieback.

    About Tipping Points:

    • Overview: Tipping Points are critical thresholds in Earth’s natural and climate systems beyond which self-reinforcing and often irreversible changes occur.
    • Mechanism: Once crossed, feedback loops accelerate transformation — e.g., melting permafrost releases methane, which increases warming and causes more melting.
    • Irreversibility: Even if greenhouse gas emissions are later reduced, many systems cannot revert to their original stable state.
    • Significance: Tipping Points determine long-term planetary stability, climate predictability, and biosphere resilience.

    Important Definitions:

    • Climate Tipping Point (IPCC): A critical threshold at which small changes in temperature or forcing cause a large, often irreversible shift in a climate subsystem.
    • Feedback Loop: A process where an initial change triggers further effects that amplify the original disturbance (positive feedback).
    • Hysteresis: The property of a system where reversing to its prior state requires conditions much different from those that caused the initial change.
    • Cascade Effect: A phenomenon where crossing one tipping point triggers others in connected Earth systems, leading to compounded impacts.
    • Thermal Tipping Point (for Coral Reefs): The temperature threshold (~1.2°C above pre-industrial) beyond which coral survival and recovery become impossible.

    Key Global Tipping Points Identified:

    • Ice Sheets: Collapse of Greenland and West Antarctic ice sheets, committing the planet to multi-metre sea-level rise.
    • Coral Reefs: Permanent dieback of warm-water reefs due to ocean warming and acidification, destroying marine biodiversity.
    • Amazon Rainforest: Shift toward a savannah ecosystem, reducing carbon storage and regional rainfall.
    • Atlantic Meridional Overturning Circulation (AMOC): Potential shutdown below 2°C, disrupting global heat distribution and monsoon patterns.
    • Permafrost Thaw: Release of methane and CO₂, reinforcing global warming.
    • Boreal Forests & Mountain Glaciers: Increased risk of widespread dieback and loss of freshwater reserves.
    • Sub-Polar Gyre (SPG): Destabilization in North Atlantic circulation, altering marine ecosystems and heat flow.

    Highlights from the Latest Reports (Global Tipping Points 2025):

    • Study Scale: Conducted by 160 scientists from 23 countries, assessing multiple Earth-system thresholds.
    • Coral Crisis: Since January 2023, 84.4% of coral reefs across 82 nations have suffered bleaching — marking the fourth global mass event, the worst on record.
    • Temperature Thresholds: Exceeding 1.5°C global warming risks triggering multiple tipping points; 1.2°C already breached for warm-water reefs.
    • AMOC Collapse Risk: Could occur below 2°C, potentially plunging northwest Europe into severe winters and disrupting global food and water systems.
    • Amazon Dieback: Widespread collapse possible below 2°C, directly affecting 100+ million people dependent on its ecosystem.
    • Interconnected Risk: Earth’s systems form a tipping network — crossing one threshold may accelerate others, creating a domino-like cascade.
    • Policy Warning: Current Paris Agreement pledges and net-zero targets are inadequate to limit warming below 2°C.
    [UPSC 2024] One of the following regions has the world’s largest tropical peatland, which holds about three years’ worth of global carbon emissions from fossil fuels, and the possible destruction of which can exert a detrimental effect on the global climate.

    Why in the News?

    The successful trial of India’s first hydrogen-powered coach at the Integral Coach Factory (ICF), Chennai, in July 2025 marks a critical milestone in the Indian Railways’ decarbonisation strategy.

    Introduction:

    With a target of achieving net-zero carbon emissions by 2030, four decades ahead of India’s national goal, the Indian Railways is reshaping its energy, infrastructure, and financing architecture to become a global model for sustainable mobility.

    Carrying over 24 million passengers and 3 million tonnes of freight daily, this transition directly supports India’s nationally determined contributions (NDCs) under the Paris Agreement.

    India’s Energy Transition Context (2025):

    • As of June 2025, over 50% of India’s installed power capacity (476 GW total) comes from non-fossil sources, five years ahead of its 2030 Paris target.
    • Renewables: Solar (110.9 GW) and wind (51.3 GW) continue rapid expansion; nuclear capacity adds 8.8 GW.
    • Electrification: 100% village electrification achieved, with household access nearing universality.
    • Challenges:
      • Fossil fuel reliance: Coal consumption rose to 21.98 EJ in 2023, up from 6.53 EJ in 1998, with petroleum demand increasing in agriculture.
      • Energy equity gaps: Access to clean cooking fuel remains uneven; LPG adoption under PM Ujjwala Yojana suffers from affordability constraints.

    Green Transition and Decarbonisation Efforts in Railways:

    1. Network Electrification: Over the past decade, the Indian Railways has electrified nearly 45,000 km of its broad-gauge network, bringing 98% of routes under electrification. This has drastically reduced diesel use and greenhouse gas emissions, marking a major shift toward energy efficiency.
    2. Renewable Integration: Renewable power capacity has reached 756 MW (553 MW solar, 103 MW wind, 100 MW hybrid). Over 2,000 stations and offices are now powered by solar energy, reducing grid dependence and promoting clean traction power.
    3. Net-Zero Buildings: Several railway complexes and offices have received the “Shunya” Net-Zero label from the Bureau of Energy Efficiency (BEE) for achieving energy neutrality and carbon efficiency.
    4. Hydrogen for Heritage Initiative: This flagship programme aims to deploy 35 hydrogen-powered train units, with the first prototype hydrogen coach rolled out in 2025, representing a major milestone in green rail mobility.
    5. Freight and Efficiency Gains: Dedicated Freight Corridors (DFCs) are projected to prevent 457 million tonnes of CO₂ emissions over the next 30 years. The goal is to increase the rail freight modal share from 27% to 45% by 2030, cutting road-sector emissions.
    6. Complementary Actions: Railways are also expanding biofuel blending, green building construction, and rolling stock modernisation with regenerative braking and energy-efficient locomotives.

    Hydrogen Coach Technology and Innovation:

    1. Fuel-Cell Mechanism: The hydrogen coach uses fuel-cell technology to generate electricity through a chemical reaction between hydrogen and oxygen, producing only water vapour as the by-product, ensuring zero tailpipe emissions.
    2. Operational Context: Designed for non-electrified heritage routes where full electrification is uneconomical, these trains combine lightweight coach design, aerodynamic efficiency, and AI-based traction optimisation to minimise operational costs.
    3. Global Positioning: With this innovation, India joins the league of nations such as Germany and Japan that are pioneering hydrogen-based railway systems as part of a wider low-carbon transport transition.

    Climate Finance and Institutional Architecture:

    1. Green Financing Framework: India has issued ₹58,000 crore worth of sovereign green bonds since FY2023, with ₹42,000 crore specifically allocated to electric locomotives, metros, and suburban rail projects.
    2. IRFC’s Role: The Indian Railway Finance Corporation (IRFC) pioneered a $500 million green bond in 2017 for refinancing electric locomotive projects, and in 2025 extended a ₹7,500 crore loan to NTPC Green Energy to support renewable generation for traction power.
    3. Multilateral Support: The World Bank’s $245 million Rail Logistics Project (2022) aims to decongest corridors and reduce transport-sector emissions through improved infrastructure efficiency.
    4. Institutional Integration: Together, these instruments embed climate goals into national capital budgeting, aligning transport infrastructure with India’s low-carbon growth pathway.

    Policy and Operational Priorities:

    1. Renewable Power Procurement: Long-term contracts with solar and wind producers are critical to ensure that electrified routes are powered by green energy rather than coal-based electricity.
    2. Green Mobility Hubs: Major stations are being redesigned as multi-modal eco-hubs with integration of EV charging stations, e-buses, and bicycle-sharing systems.
    3. Freight Decarbonisation: Emphasis on electric, LNG, and hydrogen-fuelled trucks for last-mile logistics, reducing the carbon footprint beyond rail.
    4. Rolling Stock Modernisation: Accelerated adoption of lightweight aluminium coaches, regenerative braking, and energy-efficient locomotives.
    5. Behavioural Initiatives: Introduction of green certification for trains, carbon labelling of freight, and public awareness programmes to mainstream sustainability.

    Projected Outcomes by 2030:

    1. Net-Zero Achievement: The Indian Railways aims to achieve net-zero carbon emissions by 2030, preventing an estimated 60 million tonnes of CO₂ annually, equivalent to removing 13 million cars from the roads.
    2. Economic Impact: Fuel cost savings from electrification and energy efficiency could exceed ₹1 lakh crore by 2030, freeing capital for further green infrastructure.
    3. Global Benchmark: The Indian Railways is positioned to become the world’s first large rail system to achieve net-zero operations, setting a global precedent for state-run low-carbon transport.

    Conclusion:

    1. The hydrogen-powered coach exemplifies the synergy of technology, finance, and policy in achieving sustainable national mobility.
    2. The Railways’ green transformation is both an environmental necessity and a strategic innovation model for the developing world.
    3. Its successful execution will anchor India’s net-zero and green industrialisation vision, proving that scale and sustainability can coexist profitably.

      • Demonstrated that before the 18th century, societies possessed “prescriptive knowledge” (how things worked) but lacked “propositional knowledge” (why they worked).
      • Showed that the Scientific Revolution merged science with craftsmanship, turning discovery into applied innovation.
      • Highlighted that the Enlightenment’s intellectual openness enabled acceptance of “creative destruction,” allowing new technologies to replace old ones without institutional backlash.
    2. Philippe Aghion & Peter Howitt:
      • Developed the 1992 Schumpeterian Growth Model, mathematically linking innovation, competition, and economic growth.
      • Explained that constant firm turnover—where new innovators replace old incumbents—creates long-term, stable growth.
      • Introduced the idea of “general equilibrium in innovation”, connecting household savings, financial markets, R&D investment, and production into a single dynamic framework.

  • RBI introduces Unified Markets Interface (UMI)

    Why in the News?

    RBI Governor has unveiled the Unified Markets Interface (UMI) a next-generation financial market infrastructure developed by the Reserve Bank of India (RBI).

    What is Unified Markets Interface (UMI)?

    • Overview: The UMI is a next-generation financial market infrastructure conceptualized by the Reserve Bank of India (RBI) to tokenize financial assets and settlements using the wholesale Central Bank Digital Currency (CBDC).
    • Purpose: It aims to modernize India’s financial markets by enabling blockchain-based asset transactions, improving market transparency, and streamlining settlements through digital automation.
    • Significance: The UMI represents India’s entry into asset tokenization, the conversion of real-world financial instruments into digital tokens, thereby integrating CBDC, smart contracts, and digital public infrastructure within a single interoperable ecosystem.

    Features of UMI:

    • CBDC-Enabled Settlement: Uses the wholesale Central Bank Digital Currency (CBDC) to execute high-value settlements instantly and securely.
    • Asset Tokenization: Converts traditional financial assets into digital tokens on blockchain, allowing fractional ownership and seamless transferability.
    • Unified Infrastructure: Creates an integrated, interoperable market interface linking banks, investors, and financial intermediaries on a single digital framework.
    • Smart Contract Automation: Employs programmable contracts for real-time clearing, settlement, and compliance, reducing manual intervention.
    • Transparency and Efficiency: Blockchain ensures immutable transaction records and enhances traceability, reducing fraud and settlement delays.

    Back2Basics: Asset Tokenization

    • Definition: The process of converting real-world assets, such as bonds, real estate, commodities, or equities, into digital tokens stored on blockchain networks.
    • Mechanism: Each token represents fractional ownership, enabling smaller investors to participate in high-value assets traditionally limited to institutions.
    • Technology Base: Built on blockchain and smart contracts, ensuring transparent, secure, and automated transactions.
    • RBI’s Application: Tokenized financial assets under UMI will settle through wholesale CBDC, providing real-time, tamper-proof, and traceable transactions.
