GS Paper: GS3

  • Direct Listing on Foreign Stock Exchanges

    Central Idea

    • In a landmark move, the Indian government has opened doors for select Indian companies to directly list on designated foreign stock exchanges.
    • This strategic decision aims to provide these companies with access to global capital markets and boost capital outflows, marking a significant step in India’s financial evolution.

    Direct Listing vs. Initial Public Offers (IPO)

    IPO Direct Listing
    Share Issuance New shares are created and sold. No new shares are created or sold.
    Underwriters Typically involves underwriters. No underwriters involved.
    Price Determination Price determined through negotiations. Market-driven pricing at launch.
    Lock-Up Period Common for insiders post-IPO. Typically no lock-up period.
    Regulatory Compliance Extensive financial disclosures. Regulatory requirements met.
    Capital Raising Primary goal is to raise capital. Provides liquidity to shareholders.

     

    Implementation of Companies (Amendment) Act, 2020

    • Government Notification: The Ministry of Corporate Affairs (MCA) recently issued a notification, effectively putting into action the provisions outlined in the Companies (Amendment) Act, 2020.
    • Key Enabler: This allows both listed and unlisted domestic companies to directly list their equity shares on the International Financial Services Centre (IFSC) in Ahmedabad.
    • Empowering Provision: Section 5 grants the central government the authority to permit specific classes of public companies to list specified classes of securities on foreign stock exchanges, including GIFT IFSC, Ahmedabad.
    • Streamlined Procedures: The government retains the flexibility to exempt such listings from certain procedural requirements, such as prospectus, share capital, beneficial ownership, and dividend distribution.

    Current Listing Mechanism for Foreign Bourses

    • Depository Receipts: Previously, Indian companies desiring overseas listings relied on depository receipts, such as American Depository Receipts (ADR) or Global Depository Receipts (GDR). These receipts were issued to foreign investors through Indian custodians.
    • Past Utilization: Between 2008 and 2018, 109 companies successfully raised Rs 51,847.72 crore via the ADRs/GDRs route. However, after 2018, no Indian company pursued overseas listings.

    Advantages of Direct Foreign Listing

    • Enhanced Fundraising: Direct foreign listing empowers domestic companies to access foreign markets for fundraising, offering improved valuations and exposure to foreign currencies like the US dollar.
    • Startup and Unicorn Growth: This initiative may prove particularly beneficial for startups and unicorns, providing an additional avenue for capital raising and heightened global visibility.
    • Boosting Forex Reserves: The move contributes to India’s foreign exchange reserves, strengthening the nation’s economic stability.
    • Simplified Accounting: Indian Accounting Standards (IndAS) closely align with global accounting norms, reducing the need for extensive and costly accounting preparations following US Generally Accepted Accounting Principles (GAAP) or International Financial Reporting Standards (IFRS).

    Challenges in Direct Foreign Listing

    • Valuation Discrepancies: A key challenge lies in whether global investors will assign similar valuations as Indian markets. Assessing the commercial advantages of foreign listings will be a crucial consideration for Indian companies.
    • Clarity and Details: More detailed information is essential. This includes clarity on eligible company classes, types of listed securities, permitted foreign jurisdictions and stock exchanges, and exemptions related to procedural compliance.

  • Delhi AQI worsens to ‘Severe Plus’

    Central Idea

    • As Delhi-NCR and its environs grapple with worsening air pollution, the Air Quality Index (AQI) has gained prominence as a critical measure of air quality.

    Understanding Air Quality Index (AQI)

    • AQI measures how safe the air around you is for breathing. Organizations that report AQI measure the density of various pollutants in the air (such as PM2.5, PM10, nitrogen dioxide, ozone, etc) at different monitoring stations.
    • The widely-used National Air Quality Index (NAQI) given by the Central Pollution Control Board is a 24-hour average.
    • Its unit is micrograms per cubic meter.
    • A particular amount of one pollutant may not be as harmful as the same amount of another pollutant.
    • So, each pollutant’s quantity in the air is adjusted to a common scale (say, 0 to 500) that works for all pollutants.
    • Finally, the pollutant with the worst sub-index determines the AQI for that time and location.

    Air Pollutants covered:

    • Sulphur Dioxide (SO2)
    • Nitrogen Dioxide (NO2),
    • Particulate Matter (size less than 10 µm) or PM 10
    • Particulate Matter (size less than 2.5 µm) or PM2.5
    • Ozone (O3)
    • Carbon Monoxide (CO)
    • Ammonia (NH3)

    (Pollutants that most of us NEVER heard of-)

    • Lead
    • Benzene (C6H6)
    • Benzo(a)Pyrene (BaP)
    • Arsenic(As)
    • Nickel (Ni)

    Influence on Government Policy

    • Graded Response Action Plan (GRAP): AQI plays a pivotal role in shaping government policies to combat air pollution. When AQI levels in areas like Delhi-NCR deteriorate, emergency measures, such as Stage 3 of GRAP, are activated.
    • Immediate Action: For instance, the recent dip in AQI to the ‘severe’ category prompted immediate actions. Diesel four-wheelers not meeting BS-VI compliance were prohibited, and truck entry into Delhi was restricted. Petrol cars continued to operate under regular conditions.

    About Graded Response Action Plan (GRAP)

    • The GRAP was conceived as a response to the alarming findings of a WHO study in 2014, which ranked Delhi as the most polluted city globally.
    • In 2016, the Supreme Court (M. C. Mehta vs. Union of India Case) approved GRAP after multiple expert consultations.
    • First GRAP was notified in January 2017 by the Ministry of Environment, Forest and Climate Change.

    Implementation

    • Starting in 2021, the Commission for Air Quality Management in NCR & Adjoining Areas (CAQM) has taken over the responsibility of implementing GRAP.
    • Prior to 2021, the Supreme Court-appointed EPCA would instruct states to enforce GRAP measures.
    • In 2020, the EPCA was disbanded and substituted with the Commission for Air Quality Management (CAQM).
    • The CAQM recommendations depend on the Air Quality Index (AQI) and meteorological predictions provided by the Indian Institute of Tropical Meteorology (IITM) and the India Meteorological Department (IMD).

    Revised measure implemented

    Air Quality Stage Range Measures to be implemented
    Stage I (Poor) 201-300 Enforce NGT/Supreme Court’s order on over-aged diesel/petrol vehicles.
    Stage II (Very Poor) 301-400 Implement rigorous actions to combat air pollution at identified hotspots.
    Stage III (Severe) 401-450 Impose strict restrictions on BS III petrol and BS IV diesel vehicles. Suspend physical classes in schools for primary grade children up to Class 5 in certain areas.
    Stage IV (Severe Plus) >450 Prohibit the entry of four-wheelers registered outside Delhi, except for electric vehicles, CNG vehicles, and BS-VI diesel vehicles.

     

  • White Hydrogen reserves discovered in France

    white hydrogen

    Central Idea

    • In a groundbreaking discovery, scientists searching for fossil fuels beneath northeastern France stumbled upon a vast reservoir of hydrogen.
    • Initial calculations suggest that this deposit of “white hydrogen” is among the largest ever found, estimated to range from 6 million to 250 million metric tons, holding immense promise for clean energy applications.

    Understanding White Hydrogen  

    • White hydrogen is a naturally occurring gas found within the Earth’s crust.
    • While hydrogen is the most abundant element in the universe, it typically combines with other molecules.
    • Hydrogen is hailed as a promising clean energy source for industries such as aviation, shipping, and steel production.
    • Its combustion produces only water, making it a highly eco-friendly energy option compared to solar or wind energy.

    Other types of Hydrogen

    Obtained from Production Method Carbon Emissions
    Green Hydrogen Water and renewable energy sources Electrolysis with renewables Very low to zero
    Blue Hydrogen Natural gas Steam Methane Reforming (SMR) with Carbon Capture and Storage (CCS) Reduced, but captured
    Gray Hydrogen Natural gas Steam Methane Reforming (SMR) without CCS High

    Significance of the Discovery

    • Shifting Paradigm: Historically, scientists believed that large-scale hydrogen production required lab-based processes. Hydrogen was categorized into different types based on their origin, such as gray, brown, blue, and green.
    • Untapped Potential: White hydrogen, as a naturally occurring and abundant resource, offers a significant source of clean-burning energy.
    • Natural and Cost-Effective: Unlike energy-intensive production methods, white hydrogen is naturally occurring and more cost-effective. Estimated costs for white hydrogen production are approximately $1 per kilogram, while green hydrogen costs around $6 per kilogram.

    Back2Basics: Steam Methane Reforming (SMR) Process

    smr

    SMR is the most widely used method for industrial hydrogen production, accounting for the majority of global hydrogen production.

    • Feedstock: It uses methane (CH4) from natural gas as its primary feedstock, making it a cost-effective and readily available source of hydrogen.
    • Reaction: SMR involves the reaction of methane with high-temperature steam (H2O) in the presence of a catalyst. The primary chemical reactions produce hydrogen (H2) and carbon monoxide (CO).
    • Endothermic Process: The reactions in SMR are highly endothermic, meaning they absorb a significant amount of heat energy, typically supplied through external heating.
    • By-products: In addition to hydrogen and carbon monoxide, SMR also produces carbon dioxide (CO2) and unreacted methane.

  • Narayana Murthy’s Proposition: Notion of Extended Working Hours

    narayana murthy

    70 hours Work: Narayana Murthy Suggests

    • Infosys founder N.R. Narayana Murthy’s recent call for young Indians to work 70 hours per week has ignited a debate on worker productivity in India.
    • He cited Japan and Germany as examples of nations that prospered due to longer working hours post-World War II.
    • However, his views raise questions about worker productivity, its relationship with economic growth, and India’s unique context.

    Worker Productivity vs. Labour Productivity

    • Conceptual Difference: Worker productivity involves mental activities, while labour productivity is associated with manual tasks.
    • Measurement: Productivity is typically measured as the output value per unit of labor cost.
    • Complexity in Services: In intellectual labor, measuring output independently is challenging; hence, worker income often proxies productivity.
    • Fallacious Assumption: Murthy’s assertion that increased working hours lead to higher productivity is contentious, as it could exploit workers without commensurate pay.

    Link between Worker Productivity and Economic Growth

    • Complex Relationship: While productivity improvements impact economic growth positively, the relationship is intricate.
    • Distribution of Income: India’s economic growth hasn’t necessarily benefited all income groups; wealth disparities persist.
    • Income Inequality: Income gains have disproportionately favored the top income strata, suggesting a disconnect between productivity and income distribution.
    • Factors Influencing Wealth: Factors like hereditary wealth transfers and arbitrary compensation for the super managerial class have contributed to income disparities.

    Is India’s Worker Productivity One of the Lowest?

    • Proxy Fallacy: Using income as a proxy for productivity can yield misleading conclusions.
    • Indian Workforce: Indians are among the hardest working employees globally, but they receive comparatively lower wages.
    • Contradictory Statements: Narayana Murthy’s claim about low productivity seems unsubstantiated, possibly driven by motives to push labor reforms.

    What data shows?

    • In 1980, India’s Gross Domestic Product was about $200 billion, which by 2015 exceeded $2,000 billion.
    • Income distribution data from 1980 to 2015 in India:
      1. Bottom 50% income groups experienced a 90% increase in income.
      2. Top 10% income group’s share increased from 30% to 58%.
      3. Top 0.01% experienced an increase of 1699%.
      4. Top 0.001% had an increase of 2040%.

    Impact of Informal Labor on Worker Productivity

    • Rise in Informal Employment: Economic reforms have witnessed a surge in informal employment.
    • Limited Formalization: Formalization efforts have mostly focused on tax compliance and not labor standards or conditions.
    • Exploitation in MSMEs: Even within the formal manufacturing sector, Micro-Small-Medium Enterprises (MSMEs) engage in wage cutting to maximize profits.
    • Outsourcing Practices: Large corporations outsource production to smaller labour-intensive units, exacerbating labor exploitation.

    Comparing India with Japan and Germany

    • Inadequate Comparisons: India’s unique context, including its labor force, technological trajectory, socio-cultural dynamics, and political structures, makes direct comparisons with Japan and Germany inapt.
    • Unique Development Path: India’s sustainable development requires enhancing social investments, tapping domestic consumption potential, and focusing on human-centric development.

    Conclusion

    • The call for extended working hours to boost worker productivity raises complex issues regarding labor exploitation, income distribution, and India’s economic context.
    • Direct comparisons with Japan and Germany overlook India’s unique challenges and opportunities.
    • A comprehensive approach that addresses these intricacies is essential to ensure sustainable and equitable development in India.

  • Decline in Food Safety Standards across India: A Closer Look

    food safety

    Central Idea

    • Four years after the Food Safety and Standards Authority of India (FSSAI) introduced a state-wise index to encourage improvements in food safety, alarming trends have emerged.
    • A significant number of large Indian states have witnessed a drop in their food safety scores in 2023 compared to 2019.
    • This analysis delves into the details of these findings, highlighting the key parameters, their weights, and how the states fared.

    Understanding the State Food Safety Index (SFSI)

    • FSSAI has developed the State Food Safety Index to measure the performance of states on various parameters of Food Safety.
    • It was first rolled in 2018-19.
    • This index is based on the performance of the State/ UT on five significant parameters set by the Health Ministry, namely
    1. Human Resources and Institutional Data
    2. Compliance
    3. Food Testing – Infrastructure and Surveillance
    4. Training & Capacity Building and
    5. Consumer Empowerment
    • In 2023, a new parameter, ‘Improvement in SFSI Rank,’ was added, altering the weightages of existing parameters to maintain a total score of 100.
    • The Index is a dynamic quantitative and qualitative benchmarking model that provides an objective framework for evaluating food safety across all States/UTs.

    Highlights of the 2023 Report

  • Haemoglobin isn’t used only in Blood: Scientists

    Haemoglobin

    Central Idea

    • A groundbreaking study published in Nature has unveiled an unexpected revelation: haemoglobin is not exclusive to RBCs.
    • Scientists from China have discovered that chondrocytes, the cells responsible for cartilage production, also produce haemoglobin, which appears vital for their survival.
    • For decades, textbooks have taught that haemoglobin resides solely in red blood cells (RBCs), responsible for making blood red and transporting oxygen.
    Cartilage: A tough, flexible connective tissue found throughout the human body, providing structural support and reducing friction between bones.

    About Haemoglobin

    Fact Description
    Definition A protein found in red blood cells that transports oxygen from the lungs to tissues and organs.
    Molecular Structure Composed of four subunits: two alpha-globin chains and two beta-globin chains.
    Iron-Binding Each subunit contains an iron atom that binds to oxygen, forming oxy-hemoglobin.
    Oxygen Transport Carries oxygen from the lungs to tissues and releases oxygen for cellular respiration.
    Color Gives red blood cells their red color when oxygenated and appears bluish when deoxygenated.
    Carbon Dioxide Transport Aids in transporting carbon dioxide and hydrogen ions from tissues back to the lungs for exhalation.
    Hemoglobin Variants Different types of hemoglobin, with HbA being the most common. Variants can result from genetic mutations.
    Hemoglobin Levels Vary by individual and are measured in grams per deciliter (g/dL). Normal levels range from 12 to 18 g/dL.
    Hemoglobin Disorders Genetic disorders like sickle cell disease and thalassemia are characterized by abnormal hemoglobin production.
    Iron Metabolism Adequate iron levels are essential for hemoglobin synthesis. Iron is a key component of heme in hemoglobin.
    Fetal Hemoglobin Fetal hemoglobin (HbF) has a higher oxygen affinity and aids in oxygen transfer from mother to fetus.
    Hemoglobin Tests Used for diagnosing anemia, assessing health, and monitoring medical conditions.
    Oxygen Saturation Measured as the percentage of hemoglobin molecules bound to oxygen, often using a pulse oximeter.

    New Breakthrough: Haemoglobin Bodies (Hedy)

    • Pathologists in China researching bone development, stumbled upon spherical structures resembling RBCs within chondrocytes.
    • These structures, termed “haemoglobin bodies” or Hedy, contained haemoglobin and formed large, membraneless blobs, akin to phase separation in oil and water.

    Functionality of Hedy

    • Essential for Survival: Experiments on genetically modified mice revealed that chondrocytes without haemoglobin experienced cell death, emphasizing Hedy’s vital role.
    • Oxygen Transport: Similar to RBCs, haemoglobin in chondrocytes likely serves as an oxygen store and supplier, preventing hypoxic stress (low-oxygen conditions) in cartilage cells.

    Haemoglobin’s Broader Implications

    • New Research Avenues: The discovery bridges gaps between haematology and skeletal biology, paving the way for further exploration into the relationship between haemoglobin and stem cell fate in growth plates.
    • Potential for Joint Disease Insights: Functional haemoglobin in cartilage raises possibilities of its involvement in joint diseases and bone deformities, offering fresh insights into disease mechanisms.
