  • Goods and Services Tax (GST)

    Need to deal with distortions built into GST

    op-ed snap | Economics | Mains Paper 3: Indian Economy

    The article highlights the issues with the one state one vote system adopted in the GST Council decision making.

    Context

    The Goods and Services Tax (GST) Council in India is still engaged in a discussion on whether life-saving and hard-to-come-by products should be taxed. Such delay in decision-making can largely be explained by the distorted design and incentive structure of the GST itself.

    Imbalance in collection and distribution of taxes

    • The taxes collected under GST are accumulated by the Union government and a portion is transferred back to each state under a formula.
    • As is the case with most federal countries, there is a large imbalance in the collection and distribution of taxes between states.
    • this holds true also for income accrued to, and distributed, from the GST pool.
    • Four states — Maharashtra, Tamil Nadu, Karnataka, and Gujarat contribute nearly as much as the remaining 27 states combined.
    • Most federal countries exhibit this characteristic where a few large, rich, provinces or states contribute disproportionately.

    Variation in dependence of States on transfers from the Union government

    • Only about 30 per cent of the overall revenue of the states mentioned above — Maharashtra, Tamil Nadu, Gujarat, and Karnataka — comes from the Union government.
    • But for the remaining 27 states, roughly 60 per cent of their revenues are obtained through transfers from the Union government.
    • For the smaller Northeastern states, these transfers from the Union government constitute 80-90 per cent of their total revenues.
    •  In effect, the states that contribute the most to the GST pool are the least dependent on transfers from the Union government while the ones that contribute the least are the most dependent.

    Two problems in net-transfers in India

    1) One-sided transfers

    •  In almost every federal union, net-transfers work to reduce differences in development between states over time.
    • However, Over the last 25 years or so, net transfers have become increasingly one-sided in India.
    • That is, the quantum of net-transfers diminishes, as states become more equal through such transfers.
    • But in India, the opposite has occurred.

    2) Indirect taxes and cess

    • The Union government of the last seven years has greatly exacerbated this problem through two actions.
    • First, it has reconstructed the composition of taxation away from the fair and progressive channel of direct taxation towards the inherently regressive and unfair channel of indirect taxes.
    • Second, the Union has shifted a large proportion of taxation roughly 18 per cent of its overall revenues into cesses, a special form of taxes that remain outside the GST pool and hence do not have to be shared with the states.
    • Since 2014, cess revenues grew 21 per cent every year leading to a doubling in terms of its share of GDP.

    Implications of these two problems for fiscal federalism

    • The combined effect of these problems is that all states (collectively) get a lower share of overall revenues.
    • Individual states face an ever-increasing disparity in the ratio of funds received from the Union as a proportion of taxes collected by the Union from that state.
    • This is an affront to fiscal federalism and an assault on “cooperative federalism”.

    Issue of ‘one state one vote’ system

    • States that are more dependent on transfers from the Union want to maximise GST collections while states that are less dependent can afford to be more sensitive to citizens’ concerns.
    • The case of taxes on Covid products is perhaps the starkest instance of such differences.
    • Most large states are ready to forego this tax revenue for humanitarian considerations.
    • But 19 states representing the remaining 30 per cent of the population seem keen to continue to levy GST on Covid products.
    •  These are mostly smaller states.
    • Given the smaller population of such states, the adverse impact of Covid taxes will be minimal for them.
    • But they will reap the benefits of additional revenues from GST on Covid products levied on the much larger populations of the bigger states.

    Conclusion

    When direct tax policy decisions are legislated by Parliament, which has proportional representation from states according to their size of the population, indirect tax policy decisions should not be subject to one state one vote system.

  • BRICS Summits

    BRICS

    IOCR | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    As India is gearing up to host this year’s BRICS summit, the grouping is facing fresh challenges, from disputes among member countries to tackling COVID-triggered crises and opportunities.

    What is BRICS?

    • To be clear, BRICS was not invented by any of its members.
    • In 2001, Goldman Sachs’ Jim O’Neill authored a paper called “Building Better Global Economic BRICs”, pointing out that future GDP growth in the world would come from China, India, Russia and Brazil.
    • Significantly, the paper didn’t recommend a separate grouping for them, but made the case that the G-7 grouping, made up of the world’s most industrialized, and essentially Western countries, should include them.
    • O’Neill also suggested that the G-7 group needed revamping after the introduction of a common currency for Europe, the euro, in 1999.
    • In 2003, Goldman Sachs wrote another paper, “Dreaming with BRICs: Path to 2050”, predicting that the global map would significantly change due to these four emerging economies.
    • In 2006, leaders of the BRIC countries met on the margins of a G-8 (now called G-7) summit in St. Petersburg, Russia, and BRIC was formalized that year.

    Issues in its consolidation

    • Common ground for the members was built by ensuring that no bilateral issues were brought up, but the contradictions remained.
    • Many economists soon grew tired of “emerging” economies that didn’t reach the goals they had predicted.
    • Others saw India’s closer ties with the US after the civil nuclear deal as a sign its bonds with BRICS would weaken.
    • Meanwhile, Russia, which had hoped to bolster its own global influence through the group, had been cast out of the G-7 order altogether after its actions in Crimea in 2014.
    • China, under Xi Jinping, grew increasingly aggressive, and impatient about the other underperforming economies in the group, as it became the U.S.’s main challenger on the global stage.

    Long-term prospects

    • China’s decision to launch the trillion-dollar Belt and Road Initiative in 2017 was opposed by India, and even Russia did not join the BRI plan, although it has considerable infrastructure projects with China.
    • South Africa’s debt-laden economy and the negative current account have led some to predict an economic collapse in the next decade.
    • Brazil’s poor handling during the Covid-19 crisis has ranked it amongst the world’s worst-affected countries, and its recovery is expected to be delayed.
    • India’s economic slowdown was a concern even before Covid-19 hit, and government policies like “Aatmanirbhar” were seen as a plan to turn inward.

    Issues with BRICS nations

    • Concerns about aggressions from Russia in Ukraine and Eastern Europe and China in the South China Sea, the border with India and internally in Hongkong and Xinjiang are clear visible.
    • There is creeping authoritarianism in democracies like Brazil and India have made investors question long-term prospects of the group.
    • In the market, BRICS has been mocked for being “broken”, while others have suggested it should be expanded to include more emerging economies like Indonesia, Mexico and Turkey, called the “Next-11”.

    A roadmap to progress

    • BRICS is an idea that has endured two decades, an idea its members remain committed to, and not one has skipped the annual summits held since 2009.
    • Along the way, BRICS has created the New Development Bank (NDB) set up with an initial capital of $100 billion.
    • There is a BRICS Contingent Reserve Arrangement fund to deal with global liquidity crunches, and a BRICS payment system proposing to be an alternative to the SWIFT payment system.

    Reforming the multilaterals

    • The BRICS ministerial meeting held this week sent several important signals to that end, issuing two outcome documents.
    • It included the first “standalone” joint statement on reforming multilateral institutions, including the UN and the UNSC, IMF and World Bank and the WTO.
    • It remains to be seen how far countries like China and Russia, which are already “inside the tent” at the UNSC, will go in advocating for the other BRICS members.
    • Another important agreement was the BRICS ministerial decision to support negotiations at the WTO for the waiver of trade-related intellectual property rights (TRIPs) for vaccines and medicines to tackle the Coronavirus.

    Way forward

    • What appears clear is in the post-Covid world, priorities for all economies will change, and offer up a churning in the world of the kind seen two decades ago, when the idea of a grouping of emerging economies was first floated.
    • For BRICS, the next few months could crystallize that idea, or sink it further, leaving others to wonder whether the “Rise of the Rest” as it was once called, is an idea whose time will ever come at all.

  • OBOR Initiative

    Colombo Port City Project and Chinese involvement

    IOCR | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    Sri Lanka recently passed the controversial Colombo Port City Economic Commission Bill, which governs the China-backed Colombo Port City project worth $1.4 billion, amid wide opposition to the creation of a “Chinese enclave” in the island nation.

    Colombo Port City Project

    • The Colombo Port City has grabbed headlines in Sri Lanka in recent months even as the relentless third wave of the COVID-19 pandemic sweeps through the country.
    • Almost an artificial island, the territory coming up on 2.69 square kilometers of land reclaimed from Colombo’s seafront has stirred controversy since its inception.
    • Those backing it see in that patch of land their dream of an international financial hub — a “Singapore or Dubai” in the Indian Ocean.

    When was it launched?

    • The project was launched in September 2014 by Chinese President Xi Jinping during a visit to the island nation under the Mahinda Rajapaksa administration’s second term.
    • After President Mahinda Rajapaksa was ousted in January 2015, the successor “national unity” government of Maithripala Sirisena and Ranil Wickremesinghe went ahead with the project after briefly halting it.
    • On returning to power in November 2019, the Rajapaksas vowed to expedite the project. The Sri Lankan government says the project will bring in around 83,000 jobs and $15 billion initially.

    Issues with the project

    • But skeptics claim that it could well become a “Chinese colony”, with the Bill, which is now an Act.
    • The law provides China substantial “immunity” from Sri Lankan laws, besides huge tax exemptions and other incentives for investors.

    What is the extent of China’s involvement?

    Effectively, China has substantial control over two key infrastructure projects in Sri Lanka for a century.

    • The port city project is financed chiefly through Chinese investment amounting to $1.4 billion.
    • In return, the company will receive 116 hectares (of the total 269 hectares) on a 99-year lease.
    • The city separates from but located adjacent to the Colombo Port, the country’s main harbor — is the third major port-related infrastructure project where China has a significant stake.
    • China Merchants Port Holdings has an 85% stake in the Colombo International Container Terminal under a 35-year ‘Build Operate and Transfer’ agreement with the Sri Lanka Port Authority.
    • In 2017, the Sirisena-Wickremesinghe administration, unable to repay the Chinese loan with which it was saddled by the previous government, handed over the Hambantota Port to China on a 99-year lease.

    Concerns from within Sri Lanka

    • Since its launch, the Colombo Port City project has faced opposition from environmentalists and fisherfolk, who feared that the project would affect marine life and livelihoods.
    • However, in the absence of wider political and societal support, their resistance did not dent successive governments’ resolve to pursue the project.
    • The more recent opposition was specific to the Colombo Port City Economic Commission Bill.
    • The resistance came from Opposition parties and civil society groups, including many who do not oppose the project per se, but rather its governance by “an all-powerful commission answerable to no one”.
    • Significantly, a section of Buddhist monks, wielding much influence in Sri Lankan politics and the Sinhala society, also opposed the Bill and said that it eroded Sri Lanka’s sovereignty.

  • G20 : Economic Cooperation ahead

    G7 members endorse global minimum tax

    IOCR | International Relations | Mains Paper 2: Bilateral, Regional and Global Groupings and agreements involving India

    Finance Ministers from the Group of Seven (G7) rich nations have reached a landmark accord setting a global minimum corporate tax rate, an agreement that could form the basis of a worldwide deal.

    Why a global minimum?

    • Major economies are aiming to discourage multinationals from shifting profits — and tax revenues — to low-tax countries regardless of where their sales are made.
    • Increasingly, income from intangible sources such as drug patents, software and royalties on intellectual property has migrated to these jurisdictions, allowing companies to avoid paying higher taxes in their traditional home countries.
    • With its proposal for a minimum 15% tax rate, the Biden administration hopes to reduce such tax base erosion without putting American firms at a financial disadvantage, allowing competition on innovation, infrastructure and other attributes.

    Where are the talks at?

    • The G7 talks feed into a much broader, existing effort.
    • The OECD has been coordinating tax negotiations among 140 countries for years on rules for taxing cross-border digital services and curbing tax base erosion, including a global corporate minimum tax.
    • The OECD and G20 countries aim to reach a consensus on both by mid-year, but the talks on a global corporate minimum are technically simpler and less contentious.
    • If a broad consensus is reached, it will be extremely hard for any low-tax country to try and block an accord.

    How would a global minimum tax work?

    • The global minimum tax rate would apply to overseas profits.
    • Governments could still set whatever local corporate tax rate they want, but if companies pay lower rates in a particular country, their home governments could “top-up” their taxes to the minimum rate.
    • This would eliminate the advantage of shifting profits.

    What about that minimum rate?

    • Talks are focusing on the U.S. proposal of a minimum global corporation tax rate of 15% – above the level in countries such as Ireland but below the lowest G7 level.
    • Any final agreement could have major repercussions for low-tax countries and tax havens.
    • The Irish economy has boomed with the influx of billions of dollars in investment from multinationals.
    • Dublin, which has resisted EU attempts to harmonize its tax rules, is unlikely to accept a higher minimum rate without a fight.
    • However, the battle for low-tax countries is less likely to be about scuppering the overall talks and more about building support for a minimum rate as close as possible to its 12.5% or seeking certain exemptions.

    Back2Basics: G7

    • The G7 or the Group of Seven is a group of the seven most advanced economies as per the International Monetary Fund (IMF).
    • The seven countries are Canada, USA, UK, France, Germany, Japan and Italy. The EU is also represented in the G7.
    • These countries, with the seven largest IMF-described advanced economies in the world, represent 58% of the global net wealth ($317 trillion).
    • The G7 countries also represent more than 46% of the global gross domestic product (GDP) based on nominal values, and more than 32% of the global GDP based on purchasing power parity.
    • The requirements to be a member of the G7 are a high net national wealth and a high HDI (Human Development Index).

  • Water Management – Institutional Reforms, Conservation Efforts, etc.

    ‘Sea Snot’ outbreak in Turkey

    India MappingPrelims Only | Enviro & Biodiversity | Mains Paper 3: Conservation, Environmental Pollution & Degradation, Eia

    There has been growing environmental concern in Turkey over the accumulation of ‘sea snot’, a slimy layer of grey or green sludge in the country’s seas, which can cause considerable damage to the marine ecosystem.

    What is ‘Sea Snot’?

    • ‘Sea snot’ is marine mucilage that is formed when algae are overloaded with nutrients as a result of water pollution combined with the effects of climate change.
    • A ‘sea snot’ outbreak was first recorded in the country in 2007. Back then, it was also spotted in the Aegean Sea near Greece.
    • But the current outbreak in the Sea of Marmara is by far the biggest in the country’s history.
    • The nutrient overload occurs when algae feast on warm weather caused by global warming. Water pollution adds to the problem.
    • Environmental experts have said that the overproduction of phytoplankton caused by climate change and the uncontrolled dumping of household and industrial waste into the seas has led to the present crisis.

    Where has it been found?

    • Turkey’s Sea of Marmara, which connects the Black Sea to the Aegean Sea, has witnessed the largest outbreak of ‘sea snot’.
    • The sludge has also been spotted in the adjoining Black and Aegean seas.

    How badly can the crisis affect the marine ecosystem?

    • The growth of the mucilage, which floats upon the surface of the sea like brown phlegm, is posing a severe threat to the marine ecosystem of the country.
    • Divers have said that it has caused mass deaths among the fish population, and also killed other aquatic organisms such as corals and sponges.
    • The mucilage is now covering the surface of the sea and has also spread to 80-100 feet below the surface.
    • If unchecked, this can collapse to the bottom and cover the sea floor, causing major damage to the marine ecosystem.
    • Over a period of time, it could end up poisoning all aquatic life, including fishes, crabs, oysters, mussels and sea stars.

  • Important Judgements In News

    Verdict on Maratha reservation ignores inequality within intermediate castes

    op-ed snap | Governance | Mains Paper 2: Executive & Judiciary,Laws, Institutions & Bodies Constituted For The Vulnerable Sections

    The article highlights the issues with Maratha reservation judgement delivered by the Supreme Court which rejected the positive discrimination of lower classes of dominant caste.

    About the verdict

    • The Supreme Court rendered a unanimous verdict on the validity of the SEBC Act, 2018 that was to grant reservation to Marathas.
    • The court held that the classification of Marathas as a socially and educationally backward class was unreasonable.
    • Court held that Maratha belonged to a politically dominant caste with significant economic resources.

    Justification for 50% limit

    • The court also concluded that the majority opinion in the Indra Sawhney case was correct and that the limit of 50 per cent for caste-based reservation did not need consideration by a larger bench.
    • The court justified the fixed quantitative limit on caste-based reservation by postulating that it was intrinsic to the fundamental principle of equality.
    • The court highlighted the need to safeguard the interests of unreserved sections and said that all sections have progressed after 70 years of independence.
    • Based on this, the court rejected the state’s argument that the breach of the limit was necessitated by the fact that the population of backward classes was over 80 per cent.

    Missed opportunity to acknowledge growing socio-economic differentiation within the dominant castes

    Growing income difference

    • If in 2011-12, the average per capita income of the Marathas was second only to the Brahmins at Rs 36,548, against Rs 47,427.
    • Their highest quintile -20 per cent of the caste group- got 48 per cent of the total income of the Marathas with a mean per capita income of Rs 86,750.
    • The lowest quintile earned 10 times less (Rs 7,198) and the 40 per cent poorest got less than 13 per cent of the total income of the caste — and were lagging behind the Scheduled Castes elite.
    • In fact, the mean incomes of the highest Dalit quintile, Rs 63,030, and that of the second-highest, Rs 28,897, were above those of the three lowest quintiles of the Marathas.

    What explains growing income difference

    • This is partly due to changes on the education front. 
    • The percentage of graduates among Dalits in 2004-05 was 1.9 per cent and has more than doubled to 5.1 per cent in 2011-12.
    • The corresponding figure for the OBCs was 3.5 per cent and has doubled to 7.6 per cent, while for the Marathas it was 4.6 per cent in 2004-05 and has come up to 8 per cent in 2011-12.
    • Correlatively, the percentage of salaried people among the Dalits was about 28 per cent in Maharashtra in 2011-12, as against 30 per cent among the Marathas.

    Issues with the Maratha quota judgment

    •  The Court refused to recognise the need for positive discrimination of the lower classes of the dominant castes which continue to be seen as a dominant bloc.
    • It fails to admit the complexity that the role of class has introduced in post-liberalisation India.
    • This is unequivocal confirmation of a dated approach to social realities and a purely arithmetic limit that finds no expression in the Constitution.
    • The judgement also raises the issue of judicial supremacy in the broad area of social policy as it could lead to undesirable exclusion of beneficiaries.
    • The court seems to have forgotten its own observation in NM Thomas case that functional democracy postulates participation of all sections of the people and fair representation in administration is an index of such participation.

    Conclusion

    The Supreme Court has rejected the determination of Marathas as backward by holding that their relative deprivation and under-representation with regard to other sections of the general category did not entitle them to affirmative action.

  • Financial Inclusion in India and Its Challenges

    Enabling financial inclusion

    | Economics | Mains Paper 3: Indian Economy

    The article takes an overview of the progress made by India in the financial inclusion and role played by JAM trinity in it.

    What is financial inclusion?

    Financial inclusion is defined as the availability and equality of opportunities to access financial services. It refers to a process by which individuals and businesses can access appropriate, affordable, and timely financial products and services. These include banking, loan, equity, and insurance products.

    Growing adoption of digital payment in India

    • India overtook China to register the highest number of countrywide digital payments.
    • Real-time transactions crossed 25 billion, much higher than China’s 15 billion in 2020, as per the report of ACI Worldwide.
    • The report also stated that digital payments in India are set to account for 71.7 per cent of all payments by volume by the year 2025.
    • The digital payment boom is indicative of a larger paradigm shift in the ease of access to financial services.

    What are the contributing factors

    • More and more people, across all strata, are adopting digital payments as it is convenient, safe and limits exposure.
    • It is also a result of the nudges and diligent policy and technology frameworks created by the central government in the last few years.
    • By building the Jan-Dhan-Aadhar-Mobile (JAM) and Universal Payment Interface (UPI) platform, the government has been creating the ground for greater financial inclusion.

    Significance of JAM trinity

    • While Jan Dhan was the first pillar of the ambitious JAM trinity, Aadhaar card seeding and bank account linkages to mobile numbers have empowered people in hitherto unimagined ways.
    • The JAM trinity has helped people know their account status, receive scholarships and fellowships, get fertiliser and LPG subsidy, disability pensions and farm income support — directly into their accounts.
    • The trinity also helped eliminate middlemen, frauds, and leakages due to corruption.
    • In the past one year alone, Rs 4.3 lakh crore was transferred, in over 477 crore transactions under 319 schemes.
    • With an estimated saving of Rs 1.8 lakh crore, the success of DBT is a big thumbs up for the central government.
    • The aid that reached people during the pandemic under the PM Garib Kalyan package is indicative of the success of the government’s financial inclusion and digitisation efforts.

    Conclusion

    The unmissable digital and financial revolution that has been unleashed is hard to miss for anyone. The digital journey, however, is long and one hopes to see the positive trends sustaining given their transformative impact on the lives of Indians.

    Q.Consider the following statements:

    1. The Reserve Bank of India manages and services the Government of India Securities but not any State Government Securities.
    2. Treasury bills are issued by the Government of India and there are no treasury bills issued by the State Governments.
    3. Treasury bills offer are issued at a discount from the par value.

    Which of the statements given above is/are correct?

    (a) 1 and 2 only

    (b) 3 Only

    (c) 2 and 3 only

    (d) 1, 2 and 3

    What are Government Securities?

    • These are debt instruments issued by the government to borrow money.
    • The two key categories are:
    1. Treasury bills (T-Bills) – short-term instruments which mature in 91 days, 182 days, or 364 days, and
    2. Dated securities – long-term instruments, which mature anywhere between 5 years and 40 years

    Note: T-Bills are issued only by the central government, and the interest on them is determined by market forces.

    Why G-Secs?

    • Like bank fixed deposits, g-secs are not tax-free.
    • They are generally considered the safest form of investment because they are backed by the government. So, the risk of default is almost nil.
    • However, they are not completely risk-free, since they are subject to fluctuations in interest rates.
    • Bank fixed deposits, on the other hand, are guaranteed only to the extent of Rs 5 lakh by the Deposit Insurance and Credit Guarantee Corporation (DICGC).

    Anti-hail guns to mitigate hailstorms crop damage

    | Enviro & Biodiversity | Mains Paper 1: Geographical Features & Their Location

    To help out horticulturists who face crop damage due to hailstorms, the Himachal Pradesh government will be testing the use of indigenously developed ‘anti-hail guns’.

    What are anti-hail guns?

    • An anti-hail gun is a machine that generates shock waves to disrupt the growth of hailstones in clouds, according to its makers.
    • It comprises a tall, fixed structure somewhat resembling an inverted tower, several metres high, with a long and narrow cone opening towards the sky.
    • The gun is “fired” by feeding an explosive mixture of acetylene gas and air into its lower chamber, which releases a shock wave (waves that travel faster than the speed of sound, such as those produced by supersonic aircraft).
    • These shock waves supposedly stop water droplets in clouds from turning into hailstones, so that they fall simply as raindrops.

    Answer this PYQ in the comment box:

    Q.During a thunderstorm, the thunder in the skies is produced by the

    1. meeting of cumulonimbus clouds in the sky
    2. lightning that separates the nimbus clouds
    3. violent upward movement of air and water particles

    Select the correct option using the codes given below:

    (a) 1 only

    (b) 2 and 3 only

    (c) 1 and 3 only

    (d) None of the above

    How do they ‘prevent’ a hailstorm?

    • It is this hail formation process that the shock waves from anti-hail guns try to disrupt in a radius of 500 meters, so that the water droplets fall down before they can be lifted by the updrafts.
    • The machine is repeatedly fired every few seconds during an approaching thunderstorm.
    • However, the effectiveness of anti-hail guns has remained a contentious issue.

    How do Hailstorms occur?

    • Hail is produced by cumulonimbus clouds, which are generally large and dark and may cause thunder and lightning.
    • In such clouds, winds can blow up the water droplets to heights where they freeze into ice.
    • The frozen droplets begin to fall but are soon pushed back up by the winds and more droplets freeze onto them, resulting in multiple layers of ice on the hailstones.
    • This fall and rise is repeated several times, till the hailstones become too heavy and fall down.
