Summary of "RRB NTPC Ecomomics Marathon Class 2026 | RRB NTPC Undergraduate GK GS Marathon Class"
Main ideas & lessons from the video
Marathon revision strategy (RRB NTPC UG 2026)
- The session is framed as a high-coverage “Sagar in a Pot” revision series.
- Emphasizes revising the Sagar series and using the PDF available in the app for effective memorization.
- Promises structured revision “from here till the end” to cover Economics, GK/GS, and more.
Daily timetable for classes (marathon schedule)
- 1st day: Current Affairs (already completed) + Dharmendra Sir’s Physics class (evening, already completed)
- 2nd day: Economics (9:00 AM) + Geography (4:00 PM)
- 3rd day: Maths (9:00 AM) + Chemistry (4:00 PM)
- 4th day: Reasoning (evening, 4:00 PM) + Shobhit Sir (reasoning/combined slot as stated)
- 5th day: History (4:00 PM)
- 6th day: Computer class (with emphasis that it “must take”)
Economics & national income core concepts (GK + theory with formulas)
Economic schools / “father” associations
- Karl Marx → father of socialist economics (socialism; mentions Das Kapital)
- Adam Smith → father of modern/capitalist economics (mentions Wealth of Nations, 1776)
- J. M. Keynes → father of mixed economy
- Alfred Marshall is mentioned as an option, but the emphasized answer is Adam Smith (option B).
Sectors of the economy
- Primary sector: agriculture & natural resources; lowest GDP share
- Tertiary sector: service sector; highest GDP share
- Includes examples like: education, healthcare, insurance, communication, tourism, hotels/restaurants, internet, transport, police, banking, etc.
- The video repeatedly links types of work + examples to sector classification.
National Income using the expenditure method
-
Formula: [ NI = C + G + I + (X - M) ]
-
Where:
- C = Consumption
- G = Government expenditure
- I = Investment
- X = Exports
- M = Imports
- X − M = Net exports (NX)
GDP, depreciation, and related aggregates
- Depreciation happens in capital goods (wear and tear / reduced efficiency).
- If depreciation is subtracted from GDP → NDP
- If depreciation is subtracted from GNP → NNP (video references “NAP/NNP” while explaining the relationship)
Mixed economy adoption in India (historical basis)
- Linked to the Second Five-Year Plan
- Period: 1956–1961
- Priority: heavy and basic industries
- Model: C. Mahalanobis model
- Objective: establish a socialistic society + support mixed economy adoption
Economy ideology comparisons (Capitalism / Socialism / Mixed)
Socialist economy
- Means of production owned by the government
- Government controls prices/production
- Goal: public welfare (Jan Kalyan / welfare)
- Concept attributed to Karl Marx (as stated)
Capitalist economy
- Private ownership
- Guided by market forces / “invisible hand”
- Demand & supply affect prices
- High demand + low supply → price rises; opposite → prices fall
- Emphasis on non-interference / laissez-faire
Mixed economy
- Government + private sector coexist
- Goal: public welfare, while private sector can earn profits
Taxes and planning institutions (important exam-style facts)
Direct tax vs indirect tax
- Direct tax (example: corporation tax): progressive in nature
- Indirect tax (examples): GST, VAT, sales tax, customs duty, excise duty
Economic planning and constitutional lists
- Economic planning is in the Concurrent List of the Seventh Schedule.
Lorenz curve / inequality
- Lorenz curve measures income inequality (also related to poverty in discussion)
- The distance from the line of equality indicates degree of inequality.
1991 reforms (LPG policy)
- LPG = Liberalisation + Privatisation + Globalisation
- Adopted: 24 July 1991
- Trigger: balance of payments crisis / reduced forex reserves
- Prime Minister: P. V. Narasimha Rao
- Finance Minister: Dr. Manmohan Singh
Planning Commission and NITI Aayog
- Planning Commission dissolved on 1 Jan 2015
- Replaced by NITI Aayog
- NITI Aayog described as a think tank / advisory body, promoting cooperative federalism
- Head of NITI Aayog: Prime Minister
Unemployment types, population, literacy, and social indices
Unemployment types
- Educated unemployment: due to education mismatch
- Disguised unemployment: excess workers in agriculture where marginal productivity is zero
- Frictional unemployment: temporary unemployment between jobs (time lag)
Population density (2011)
- Compares India-wide and state/UT figures; highlights Bihar as highest (as stated)
- Mentions minimum-density example(s), e.g., Arunachal Pradesh
Literacy (2011) and gender gap
- Overall literacy: ~74.04%
- Male: ~82.14%
- Female: ~65.46%
- Gender gap: ~16.68%
- Highest literacy: Kerala (and strong mention of Lakshadweep)
- Lowest literacy: Bihar (as stated)
Sex ratio (2011)
- Total sex ratio: ~943 (as stated)
- Mentions child sex ratio examples (e.g., Arunachal highest, Haryana lowest—values in subtitles)
Gini coefficient / inequality
- 0 = complete equality
- 1 = complete inequality
- Measures income inequality
Kuznets curve
- Discussed as a relationship between development and inequality (conceptual explanation)
HDI (Human Development Index)
- Issued by UNDP
- Dimensions:
- Healthy life
- Knowledge/education
- Standard of living
- First report: 1990
Innovation Index (2025)
- India rank: 38 among 139 countries
- Issued through WIPO
Monetary policy & RBI tools (repo/CRR/SLR/OMO etc.)
Repo & reverse repo
- Repo rate: RBI lends to banks; used for short-term
- Reverse repo rate: mentioned (banks lend to RBI)
Inflation control logic
- Increasing repo rate → reduces liquidity → helps control inflation.
CRR (Cash Reserve Ratio)
- Portion of deposits kept with RBI (no interest stated)
- Higher CRR → lower liquidity → lower money multiplier
SLR (Statutory Liquidity Ratio)
- Portion kept safe: cash/gold/securities
- Higher SLR → less liquidity
Open Market Operations (OMO)
- RBI buys/sells government securities
- Purpose: liquidity adjustment
- Buying → liquidity up
- Selling → liquidity down
Money multiplier
-
Formula: [ m = \frac{1}{r} ]
-
Inverse relation: higher reserves ratio → lower money multiplier.
Other key institutions & indices (quick facts)
- WTO: established 1 Jan 1995; HQ Geneva; predecessor GATT
- IMF: founded July 1944; HQ Washington, DC; “twin institution” with World Bank
- UNCTAD: established 1964; HQ Geneva
- World Bank: long-term development and reconstruction assistance
- ADB: established 1966; HQ Manila; 68 members (as stated)
- BRICS: Brazil, Russia, India, China, South Africa
- CPI (Consumer Price Index): base year 2011–12; rural/urban/composite variants described
Methodology / instruction-like content (detailed bullets)
Revision approach
- Use the Sagar series:
- If not read: start with questions first to see improvement.
- If already read: revise systematically “from here till the end.”
- Keep PDFs from the app for quick reference.
- Maintain continuous answering during the marathon (“keep giving your answers”).
- Follow the provided timetable and attend each day’s subject blocks.
Economics question-solving patterns
- Father/creator questions: map person → ideology/school → named book (when applicable).
- Sector classification: map each activity to:
- Primary = natural resources + agriculture/allied
- Tertiary = services (education, healthcare, transport, banking, etc.)
- National income formula expansion:
- Memorize: NI = C + G + I + X − M
- For MCQs, convert X − M into NX.
- GDP/Depreciation: depreciation relates to capital goods; subtracting gives NDP.
- Tax classification: decide whether it’s direct (income/profit) or indirect (goods/services/transactions).
Monetary policy tools
- Treat inflation control as a mix of:
- Monetary measures (RBI): repo/CRR/SLR/OMO
- Fiscal measures (government): taxation + reducing expenditure
- Apply the effect chain:
- Repo ↑ → interest rates ↑ → liquidity ↓
- CRR ↑ / SLR ↑ → liquidity ↓ → money multiplier ↓
- OMO buy govt securities → liquidity ↑; OMO sell → liquidity ↓
