✅Class 12: Introductory Macroeconomics

Chapter 1 - Introduction to Indian Economic Development
Introduction
1. Macroeconomics vs. Microeconomics:
  • 1.1 Definition:
    • Macroeconomics studies the economy as a whole, focusing on aggregate variables like total production, total employment, and price levels.
    • Microeconomics deals with individual economic agents and their decisions, focusing on how they respond to and affect supply and demand in markets.
  • 1.2 Key Concerns:
    • Macroeconomics: Economic health, inflation, unemployment, overall economic policy.
    • Microeconomics: Individual satisfaction, profit maximization, cost minimization.
2. Simplifications in Macroeconomic Analysis:
  • 2.1 Aggregate Analysis:
    • Macroeconomics often simplifies the economy by considering all goods and services as a single representative entity, reflecting general levels of production, price, and employment.
  • 2.2 Limitations:
    • Overlooking specific characteristics of individual sectors can lead to oversimplifications. Sometimes, it's beneficial to consider sectors separately (e.g., agriculture vs. industry).
3. Interdependence and Sectoral Analysis:
  • 3.1 Importance:
    • Recognizing the interdependence or rivalry between different sectors (e.g., household, business, government) can provide a deeper understanding of economic dynamics.
  • 3.2 Diverse Categories:
    • Different types of goods (agricultural, industrial, and services) may need separate consideration due to their unique production conditions, prices, and employment levels.
4. Link Between Microeconomics and Macroeconomics:
  • 4.1 Basis in Microeconomics:
    • Macroeconomics is rooted in microeconomic principles, studying aggregate effects of individual market behaviors.
  • 4.2 Going Beyond:
    • Addresses situations where markets don't exist, fail to achieve equilibrium, or when societal goals require modifying market outcomes.
5. Role of Macroeconomic Policy:
  • 5.1 Decision-makers:
    • Policies are implemented by the state or statutory bodies (e.g., RBI, SEBI) with public goals defined by law or constitution, differing from individual economic agents.
  • 5.2 Objectives:
    • Policies often aim to allocate resources for public needs, not just economic objectives, serving the welfare of the country and its people as a whole.
6. Economic Agents:
  • 6.1 Definition:
    • Individuals or institutions making economic decisions, such as consumers, producers, and various entities like the government, corporations, banks.
7. Adam Smith's Contribution:
  • 7.1 Legacy:
    • Considered the founding father of modern economics, advocating that individual self-interest leads to overall economic well-being.
  • 7.2 Famous Work:
    • "An Enquiry into the Nature and Cause of the Wealth of Nations" (1776) supports the concept of a free-market economy.
Emergence of Macroeconomics
  • 1.1 Context:
    • Emerged as a distinct field after the publication of "The General Theory of Employment, Interest and Money" by John Maynard Keynes in 1936.
  • 1.2 Pre-Keynesian Thought:
    • The classical tradition believed all laborers willing to work would find employment and all factories would operate at full capacity.
2. The Great Depression and Keynesian Economics:
  • 2.1 Economic Crisis:
    • The Great Depression (1929 onwards) caused severe drops in output and employment in Europe, North America, and globally.
  • 2.2 Impact:
    • Significant unemployment and idle factories due to low market demand.
    • In the USA, unemployment rose from 3% (1929) to 25% (1933); aggregate output fell by approximately 33%.
3. Keynes' Contributions:
  • 3.1 New Economic Thinking:
    • Keynes challenged classical economics, introducing theories explaining prolonged unemployment.
  • 3.2 Macroeconomic Approach:
    • Focused on the economy as a whole, examining interdependence between sectors.
  • 3.3 Legacy:
    • His work laid the foundation for modern macroeconomics.
4. John Maynard Keynes: Brief Biography:
  • 4.1 Personal and Professional Life:
    • Born in 1883, educated at King's College, Cambridge, later becoming its Dean.
    • Active in international diplomacy post-World War I.
  • 4.2 Publications:
    • Predicted issues with post-WWI peace agreements in "The Economic Consequences of the Peace" (1919).
    • "General Theory of Employment, Interest and Money" (1936) is considered one of the 20th century's most influential economic works.
  • 4.3 Other Ventures:
    • Also known for his acumen as a foreign currency speculator.
Present Context of Macroeconomics
1. Historical Context of Macroeconomics:
  • 1.1 Capitalist Economy Focus:
    • The book focuses on economies where production is primarily by capitalist enterprises.
  • 1.2 Characteristics of Capitalist Economies:
    • Private ownership of production means.
    • Production for market sale.
    • Wage labor existence.
2. Capitalist Production Dynamics:
  • 2.1 Factors of Production:
    • Entrepreneurs, capital, natural resources (land), and labor.
  • 2.2 Revenue Utilization:
    • Payments for land (rent), capital (interest), labor (wages), and entrepreneur's profit.
  • 2.3 Investment Expenditure:
    • Profits are often reinvested to enhance production capacity.
3. Global Prevalence of Capitalism:
  • 3.1 Historical Emergence:
    • Capitalist countries emerged over the last 300-400 years.
  • 3.2 Limited Capitalist Economies:
    • True capitalist economies are primarily in North America, Europe, and parts of Asia.
4. Non-capitalist Production:
  • 4.1 Variations in Developing Countries:
    • Many underdeveloped countries feature non-capitalist production, such as family-based agriculture.
  • 4.2 Tribal Societies:
    • Collective land ownership; capitalist analysis inapplicable.
5. Economic Sectors:
  • 5.1 Firms:
    • Production units in capitalist economies are driven by profit motive and market sales.
  • 5.2 Government:
    • Role includes law enforcement, production, public infrastructure, education, health services, etc.
  • 5.3 Households:
    • Consumption decision-makers, also engage in saving, tax payment, and labor provision.
  • 5.4 External Sector:
    • Engages in trade (exports and imports) and capital transactions with other countries.
6. Macroeconomics: Scope and Significance:
  • 6.1 Aggregate Economic Variables:
    • Focuses on the economy's aggregate aspects and interlinkages between sectors.
  • 6.2 Distinction from Microeconomics:
    • Unlike microeconomics (focused on specific sectors), macroeconomics considers the whole economy.
  • 6.3 Origin:
    • Emerged in the 1930s with Keynes' work during the Great Depression.
  • 6.4 Applicability Limitations:
    • Primarily relevant to capitalist economies; may not fully represent developing countries.

Basics of Macroeconomics
1. Introduction to Macroeconomics:
  • 1.1 Key Inquiry:
    • What factors contribute to the wealth of a nation?
  • 1.2 Observation:
    • Natural resources don't equate to wealth; their utilization does.
2. Production Flow:
  • 2.1 Nature of Economic Wealth:
    • Depends on how resources contribute to production and income.
  • 2.2 Production Process:
    • Interaction between human energy, environment, and technology.
3. Commodities and their Journey:
  • 3.1 Definition of 'Final Goods':
    • Goods not undergoing further transformation.
  • 3.2 Consumption Goods vs. Capital Goods:
    • Consumption goods: for immediate consumption.
    • Capital goods: aid in production processes.
4. Intermediate Goods:
  • 4.1 Not Final Goods:
    • Used as inputs for other commodities' production.
5. Quantifying Economic Activity:
  • 5.1 Measuring Aggregate Level:
    • Through monetary value of final goods.
  • 5.2 Avoiding Double Counting:
    • Intermediate goods' value is included in final goods.
6. Stocks vs. Flows:
  • 6.1 Understanding the Concepts:
    • Stocks: Quantities measured at one point in time.
    • Flows: Quantities measured over a period of time.
7. Investment in the Economy:
  • 7.1 Gross Investment:
    • The total value of capital goods produced.
  • 7.2 Depreciation:
    • The annual allowance for capital goods' wear and tear.
  • 7.3 Net Investment:
    • Gross investment minus depreciation.
8. Final Output Categories:
  • 8.1 Consumer Goods:
    • Sustain population consumption.
  • 8.2 Capital Goods:
    • Purchased for business operations.
9. Trade-off and Economic Expansion:
  • 9.1 Immediate Scenario:
    • More capital goods, less consumer goods.
  • 9.2 Long-term Impact:
    • More capital goods enable higher future production capacity.
10. Circular Flow of Economic Activity:
  • 10.1 Income as Purchasing Power:
    • Earnings from factors of production enable commodity purchase.
  • 10.2 Production and Consumption Interlink:
    • Circular causation between production, earnings, and spending.
 
Circular Flow of Income and Circulations
1. Circular Flow of Income and National Income Calculation
  • The economy consists of two main entities: households and firms.
  • Households own the factors of production and consumption of goods; firms produce goods and services.
  • Income flows circularly between these entities.
2. Contributions to Production a. Human labor - earns wages. b. Capital - earns interest. c. Entrepreneurship - earns a profit. d. Fixed natural resources (land) - earns rent.
3. Simplified Economy Assumptions
  • No savings, government, or trade.
  • Households spend their entire income on domestic firms' goods/services.
4. Aggregate Consumption
  • Equal to aggregate expenditure on goods and services.
  • Total income returns to producers as revenue.
5. Income, Expenditure, and Production
  • Represented as flows in the economy.
  • Aggregate spending equals aggregate income earned by factors of production.
6. Three Methods of Calculating Aggregate Value a. Expenditure Method: Measuring the total spending received by firms for their goods/services. b. Product Method: Measuring the total value of goods and services produced. c. Income Method: Measuring the total income paid to factors of production.
7. Macroeconomic Models
  • Simplified representations of the economy.
  • Essential for understanding economic functioning but doesn’t capture every detail.
8. The Product or Value Added Method
  • Aggregate value is the sum of net contributions (value added) by all firms.
  • Avoids double counting by subtracting the value of intermediate goods.
9. Gross vs. Net Value Added
  • Gross includes depreciation; net does not.
10. Inventories
  • Unsold finished goods, semi-finished goods, or raw materials.
  • Change in inventories is considered an investment.
  • Can be planned or unplanned.
11. Types of Investments a. Change in inventories. b. Fixed business investment (e.g., machinery, equipment). c. Residential investment (e.g., housing facilities).
12. Gross Domestic Product (GDP)
  • The sum of the gross value added of all firms in the economy.
  • A measure of the aggregate value of goods and services produced.
 
GDP Calculation Methods
  1. Product or Value Added Method
      • Focuses on the total production value of goods and services.
      • Avoids double counting by considering only the 'value added'.
      • Example:
        • Two producers: Wheat Farmers and Bakers.
        • Farmers sell Rs 50 worth of wheat to Bakers.
        • Bakers produce Rs 200 worth of bread.
        • Value added by Farmers = Rs 100.
        • Value added by Bakers = Rs 150 (Rs 200 - Rs 50).
        • Total GDP = Rs 250 (Rs 100 + Rs 150).
  1. Expenditure Method
      • Considers the total expenditure made in the economy.
      • Components:
        • C: Consumer expenditure
        • I: Investment expenditure
        • G: Government expenditure
        • X: Exports
        • M: Imports
      • Formula: \( GDP = C + I + G + X - M \)
  1. Income Method
      • Focuses on the total income earned by the factors of production.
      • Components:
        • W: Wages
        • P: Profits
        • In: Interest
        • R: Rents
      • Formula: \( GDP = W + P + In + R \)
  1. Factor Cost, Basic Prices, and Market Prices
      • Factor Cost: Payment to production factors, excluding any taxes.
      • Basic Prices: Factor Cost + Net production taxes (production taxes - production subsidies).
      • Market Prices: Basic Prices + Net product taxes (product taxes - product subsidies).
  1. Important Concepts
      • Value Added: Production value of a firm - Value of intermediate goods used.
      • Intermediate Goods: Goods completely used up in the production process.
      • Depreciation: Value accounting for wear and tear of capital.
      • Inventories: Unsold finished/semi-finished goods or raw materials carried from one year to the next.
      • Investment: Addition to a firm's capital stock, includes change in inventories, fixed business investment, and residential investment.
      • Planned vs. Unplanned Inventories:
        • Planned: Expected changes in inventory levels.
        • Unplanned: Unexpected changes due to varying sales.
Macro-Economic Identities
  1. Gross Domestic Product (GDP)
      • Total value of goods and services produced within a country's borders in a specific time period.
      • Reflects the health of a country's economy.
      • Includes domestic production by foreign companies, and excludes citizens' production abroad.
  1. Gross National Product (GNP)
      • GDP plus net factor income from abroad (income earned by domestic factors of production employed globally minus income earned by foreign factors employed domestically).
      • Reflects the total income of a country's residents.
  1. Net National Product (NNP)
      • GNP minus depreciation (the loss in value of capital goods over time).
      • Shows the net output value accounting for resources that have been used up in the production process.
  1. National Income (NI)
      • NNP at market prices minus net indirect taxes (indirect taxes minus subsidies).
      • Represents the total amount of money earned within a country.
  1. Personal Income (PI)
      • NI adjusted for (minus) undistributed profits, net interest payments made by households, and corporate taxes, and (plus) transfer payments to households.
      • Amount of money that households receive before personal taxes.
  1. Personal Disposable Income (PDI)
      • PI minus personal tax payments and non-tax payments.
      • Money that households have to spend or save after taxes.
  1. National Disposable Income
      • Net National Product at market prices plus other current transfers from the rest of the world.
      • Represents the total income available to the nation for consumption and saving.
  1. Private Income
      • Includes various sources of private sector income, including domestic factor income, national debt interest, net factor income from abroad, and current transfers from the government.
      • Reflects the total income received by the private sector from all sources.
  1. Basic National Income Aggregates
      • GDP at Market Prices: Total value of goods and services produced domestically, valued at market prices.
      • GDP at Factor Cost: GDP at market prices minus net product taxes.
      • Net Domestic Product at Market Prices: GDP minus depreciation.
      • NDP at Factor Cost: Income earned by factors in domestic production, adjusted for taxes.
      • Gross National Product at Market Prices: GDP plus net factor income from abroad.
      • GNP at Factor Cost: GNP minus net product taxes.
      • Net National Product at Market Prices: GNP minus depreciation.
      • NNP at Factor Cost (National Income): Total income earned by a nation's factors of production.
      • GVA at Market Prices, Basic Prices, and Factor Cost: Different measures of economic output and income, adjusting for taxes and subsidies.
Nominal and Real GDP
  1. Nominal vs Real GDP
      • Nominal GDP: Value of all goods and services produced, calculated at current prices. It doesn’t account for changes in price levels (inflation or deflation).
      • Real GDP: Adjusts nominal GDP by considering price changes and inflation, allowing a more accurate comparison across different time periods. It's calculated using constant prices from a base year.
  1. Importance of Real GDP
      • Helps in comparing GDP figures across different time periods without the distortion caused by price changes.
      • Ensures changes in GDP reflect actual changes in production, not just price changes.
  1. GDP Deflator
      • Measures price inflation/deflation with respect to a specific base year.
      • Calculated as: (Nominal GDP/Real GDP) x 100
      • A GDP deflator of 150% indicates prices have increased by 50% since the base year.
  1. Consumer Price Index (CPI)
      • Measures the average change in prices over time that consumers pay for a basket of goods and services.
      • Calculated by taking price changes for each item in the predetermined basket and averaging them; changes in CPI are used to assess price changes associated with the cost of living.
  1. Wholesale Price Index (WPI)
      • Measures the changes in prices received by wholesalers.
      • Used as a measure of inflation in some countries, or to assess the cost of living adjustments in business contracts.
  1. Differences Between GDP Deflator and CPI
      • Composition: CPI includes only goods and services consumed by households and imports, while GDP deflator includes all goods and services produced domestically.
      • Basket of Goods: CPI uses a fixed basket of goods, while GDP deflator’s basket can change year by year based on production.
      • Imports: CPI includes imports, GDP deflator does not.
 
GDP and Welfare
  1. GDP as an Indicator of Welfare?
      • GDP measures the total value of goods and services produced within a country's borders in a specific time period.
      • Though it's often used as a welfare indicator, GDP doesn’t directly measure the well-being of individuals.
  1. Limitations of GDP as a Welfare Indicator
    1. Unequal Distribution of Wealth
        • An increase in GDP doesn't guarantee a proportional increase in welfare for everyone.
        • Scenario: If GDP increases but the wealth is concentrated among a small percentage of the population, the majority may not experience improved well-being.
    2. Non-monetary Exchanges
        • GDP calculations typically don't account for unpaid work (e.g., domestic household work) or barter exchanges (goods or services exchanged without money).
        • This can lead to underestimation of actual economic activity, especially in developing regions with substantial informal sectors.
    3. Externalities
        • Negative Externalities: Harmful effects (e.g., pollution) caused by production activities aren't deducted from GDP. This can lead to overestimation of welfare.
        • Positive Externalities: Benefits provided without a direct payment (e.g., education, public health initiatives) aren't added to GDP, potentially leading to underestimation of welfare.
  1. Conclusion
      • While GDP is a valuable economic indicator, its scope is limited when assessing the overall welfare of a population.
      • Factors like income distribution, non-monetary contributions, and externalities must also be considered for a comprehensive view of societal well-being.
Summary
  1. The Circular Flow of the Macroeconomy
      • Concept: Firms produce goods/services using inputs from households, and households purchase these outputs, creating a circular economic flow.
      • Income generation: Households earn income by providing services (like labor) to firms.
  1. Measuring Aggregate Value
      • Three methods to calculate the total value of goods and services (aggregate income) in an economy:
          1. Income Method: Tallying the total payment made to factors of production (e.g., wages, rent).
          1. Product Method: Calculating the total value of goods and services produced, avoiding double counting by excluding intermediate goods.
          1. Expenditure Method: Assessing the total spending on final goods and services.
  1. Investment in the Economy
      • Goods purchased for investment purposes enhance the productive capacity of firms.
  1. Categories of Aggregate Income
      • Different types based on recipients:
        • GDP: Total production within a country's borders.
        • GNP: GDP plus income from non-resident domestic sources minus income sent abroad.
        • NNP (at market price and factor cost): GNP minus depreciation; at factor cost, it excludes indirect taxes and includes subsidies.
        • PI: Income received by households (includes transfer payments, excludes corporate taxes and undistributed profits).
        • PDI: PI after taxes and non-tax payments, representing disposable income for households.
  1. Price Indices and Real Values
      • Importance: Allow comparison over time by adjusting for price changes.
      • Types:
          1. GDP Deflator: Measures price changes in all domestically produced goods and services.
          1. Consumer Price Index (CPI): Measures the price of a basket of consumer goods and services.
          1. Wholesale Price Index (WPI): Tracks price changes at the wholesale level.
  1. GDP and Welfare
      • Limitation: GDP measures economic activity but doesn't directly reflect citizens' well-being or account for distribution disparities, non-monetized services, or externalities.
 
 
 
 
 
Chapter 3 - Money and banking
The Role of Money
  1. Introduction to Money
      • Definition: Money is a universally accepted medium of exchange in an economy.
      • Context: Not applicable in a single-individual economy or where market transactions don't exist (e.g., an isolated self-sustaining family).
  1. Barter System
      • Concept: Direct exchange of goods/services without using money.
      • Limitation: Requires a double coincidence of wants, which is often impractical and inefficient due to high search costs.
  1. Necessity of Money
      • Facilitates transactions: Acts as an intermediate acceptable to all trading parties, simplifying the exchange process.
      • Eliminates inefficiencies: Avoids the complications of barter systems by providing a standard medium for trade.
  1. Functions of Money
      • Primary role: Facilitates smooth transactions and exchanges in an economy.
      • Other roles/functions: The content hints at additional purposes served by money, which are likely detailed in the following sections (not provided in the excerpt).
 
Money and its Functions
  1. Primary Functions of Money 1.1. Medium of Exchange - Facilitates trade by eliminating the challenges of the barter system (the double coincidence of wants). - Universally acceptable as payment for goods/services.
      2. 1.2. Unit of Account - Standardizes the measurement of value in an economy. - Prices of goods/services are expressed in monetary units, simplifying valuation and comparison.
      1.3. Store of Value - Preserves wealth for future use. - Non-perishable, low storage cost, and easily retrievable compared to physical commodities. - Stability in money's value is crucial for effectively performing this function.
  1. Relative Price and Value of Money
      • Expresses the value of one commodity in terms of another.
      • The value of money can be calculated in terms of goods/services.
      • A general increase in price levels indicates a reduction in money’s purchasing power.
  1. Deficiencies of the Barter System
      • Inconvenience in storing wealth.
      • Difficulties in carrying wealth forward due to perishability and storage issues of commodities.
      • Challenges in deferred payments.
  1. Digital Transformation and Cashless Society
      • Description: An economy primarily based on digital/electronic transactions instead of physical cash.
      • Advantages: Increased convenience, security, and potential for financial inclusion.
      • Initiatives in India: Jan Dhan accounts, Aadhar-enabled payment systems, e-Wallets, National Financial Switch (NFS), etc.
      • Impact: Enhanced reach due to widespread mobile and smartphone penetration.
Demand and Supply of Money
  1. Demand for Money
      • Determined by the value of transactions; more transactions require more money.
      • Influenced by income: higher income leads to a higher demand for money.
      • Affected by interest rates: higher rates decrease the demand for holding money (opportunity cost).
  1. Supply of Money
      • Constituents: cash and various forms of bank deposits.
      • Created by the central bank and commercial banking system.
      2.1. Central Bank (e.g., Reserve Bank of India)
      • Issues currency.
      • Controls money supply using tools like bank rates, open market operations, and reserve ratios.
      • Maintains foreign exchange reserves.
      • Acts as a banker to the government and commercial banks.
      2.2. Commercial Banks
      • Accept public deposits and create loans.
      • Profit from the interest rate spread (difference between interest paid on deposits and received on loans).
  1. Money Creation by the Banking System
      • Based on the fraction of deposits retained as reserves, banks lend out the rest.
      • The creation of new deposits through lending effectively increases the money supply.
      3.1. Balance Sheet of a Fictional Bank
      • Demonstrates how banks maintain assets (loans, reserves) and liabilities (deposits).
      3.2. Limits to Credit Creation and Money Multiplier
      • Central banks impose reserve requirements (CRR) to prevent over-lending.
      • Banks can create loans/money up to a limit determined by their reserves and the CRR.
      • The process iterates until the maximum money creation capacity is reached, given the reserve ratio.
      • The money multiplier effect: indicates how an initial deposit can lead to a larger increase in the total money supply.
Key Takeaways:
  • The demand for money is influenced by factors like transaction needs, income levels, and interest rates.
  • Money supply involves the coordinated actions of the central bank and commercial banking system.
  • Banks can create money through lending, but this ability is regulated by central bank-imposed reserve requirements to ensure financial stability.
  • The concept of the money multiplier reveals the potential of banks to amplify the initial deposits into a significantly larger money supply.
Policy Tools to Control Money Supply
  1. Central Bank and Money Supply
      2. 1.1 Role of Central Bank - Sole issuer of currency. - Lender of last resort for commercial banks. - Controls money supply using quantitative and qualitative tools.
      1.2 Quantitative Tools - Change in Cash Reserve Ratio (CRR). - Adjustment of bank rate. - Open Market Operations (OMOs): buying/selling government bonds.
      1.3 Qualitative Tools - Moral suasion. - Changing margin requirements for loans.
      1.4 Effects of Reserve Ratio Change - Increase leads to decreased lending, and reduced money supply. - Decrease can increase the money supply.
  1. Open Market Operations
      2. 2.1 Types of OMOs - Outright: permanent, no promise of future buyback/sale. - Repo (repurchase agreement) and reverse repo: temporary, with specified buyback/sale terms.
      2.2 Impacts on Money Supply - Buying securities: increases reserves, raises money supply. - Selling securities: decreases reserves, reduces money supply.
  1. Influence of Bank Rates
      • An increase makes loans expensive and reduces the money supply.
      • Decrease makes loans cheaper, and increases money supply.
  1. Demand for Money
      2. 4.1 Motives for Holding Money - Transaction motive: day-to-day transactions. - Speculative motive: expectation of interest rate movements and bond prices.
      4.2 Factors Affecting Demand - Total value of transactions. - Interest rates (inverse relation for speculative demand).

Chapter 4 - Determination of Income and Employment
Introduction

1. Objective of Macroeconomics

  • Main Goal: Develop models to describe processes determining key economic variables.
  • Focus: Understand the causes behind economic fluctuations, price changes, and unemployment rates.

2. Macroeconomic Models

  • Purpose: Theoretical tools for explaining economic phenomena.
  • Complexity: Can't account for all variables simultaneously.

3. Ceteris Paribus Assumption

  • Meaning: 'Other things remaining equal'.
  • Application: Focus on one variable while holding others constant.
  • Importance: Simplifies theoretical analysis.

4. Analyzing Macroeconomic System

  • Procedure: Solve for one variable in terms of others, then substitute into subsequent equations for complete solutions.
  • Methodology: Reflects systematic approach to understanding complex economic interactions.

5. Determination of National Income

  • Context: Analyzed under fixed final goods prices and constant interest rates.
  • Theoretical Model: Based on John Maynard Keynes' theory.
  • Keynes' Influence: Revolutionized understanding of income determination.
 
Aggregate Demand and its Components

1. Aggregate Demand: Ex Post and Ex Ante

  • Ex Post: Actual values measured by activities within the economy in a year.
  • Ex Ante: Planned values of consumption, investment, or output of final goods.

2. Consumption

  • Determined mostly by household income.
  • Consumption Function: Describes the relation between consumption and income.
    • Formula: ( C = C + cY )
    • ( C ): Autonomous consumption (independent of income).
    • ( cY ): Induced consumption (depends on income).
  • Marginal Propensity to Consume (MPC):
    • Change in consumption per unit change in income.
    • Lies between 0 and 1.
  • Example: If the consumption function is ( C = 100 + 0.8Y ), autonomous consumption is 100 and MPC is 0.8.

3. Savings

  • Part of income is not consumed.
  • Savings Function: ( S = Y - C )
  • Marginal Propensity to Save (MPS):
    • Change in savings per unit change in income.
    • Calculated as

4. Investment

  • Addition to physical capital or change in inventory.
  • Investment Demand: Assumed to be constant for simplicity (autonomous).
    • Formula: ( I = I ) (constant).

Determination of income in two-sector model

1. Two-Sector Model: Income Determination

  • Ex ante aggregate demand: Sum of ex-ante consumption and ex-ante investment.

2. Market Equilibrium

notion image

3. Ex Ante vs. Ex Post

  • ( Y ) on the left of the equilibrium equation: Ex ante output or planned supply.
  • The right side of the equation: Ex ante or planned aggregate demand.
  • Equality applies only in market equilibrium.
  • Not to be confused with the accounting identity (Y = C + I), which holds for ex-post values.

4. Inventory Investment

  • Refers to change in a firm's stock of finished goods.
  • Positive: Increase in inventory.
  • Negative: Depletion of inventory.
  • Can be planned or unplanned.
    • Unplanned inventory investment occurs when actual sales differ from planned sales.

5. Introduction of Government

notion image

6. GDP and National Income

  • Without indirect taxes and subsidies from the government, GDP equals National Income.
  • ( Y ) referred to as GDP or National Income interchangeably.
 
Determination of Equilibrium Income in the Short Run

1. Equilibrium Income: Short Run

  • Fixed price level justified by:
      1. Presence of unused resources.
      1. Simplification for initial analysis.

2. Macroeconomic Equilibrium (Fixed Price)

  • Graphical Method:
    • Investment function: ( I = I ) (autonomous).
    • Aggregate Demand (AD): Sum of consumption and investment.
    • Supply-side: Represented by a 45-degree line (fixed price).
    • Equilibrium: Where AD intersects the supply line.
  • Algebraic Method:
      • notion image

3. Autonomous Change: Effects

  • Changes in consumption or investment alter AD, affecting equilibrium income.
  • Increased investment shifts AD upwards, raising income.
  • The multiplier effect: Increment in AD leads to a larger increase in income/output.

4. The Multiplier Mechanism

  • Initial autonomous expenditure generates rounds of increased production, income, and consumption
notion image

5. Paradox of Thrift

  • Increased saving (higher mps) doesn't raise total savings; may reduce or keep it unchanged.
  • Reduced consumption lowers AD, causing a production cut, lower income, and hence lower or unchanged savings.

6. Effects of Changing Parameters

notion image
 
Additional Concepts

1. Equilibrium Output and Employment

  • Equilibrium output doesn't imply full employment.
  • Full employment: All production factors are fully utilized.
  • Equilibrium can exist with unemployment (deficient demand) or over-employment (excess demand).

2. Deficient vs Excess Demand

  • Deficient Demand:
      1. Occurs when equilibrium output is below full employment level.
      1. Not enough demand to employ all production factors.
      1. Leads to price declines in the long run.
  • Excess Demand:
      1. Occurs when equilibrium output exceeds full employment level.
      1. Demand surpasses output at full employment.
      1. Results in price increases in the long run.

3. Market Equilibrium

  • Achieved when aggregate demand equals the aggregate supply of final goods.
  • Components of aggregate demand: ex-ante consumption, ex-ante investment, government spending.
  • Marginal Propensity to Consume (MPC): Rate of increase in consumption per unit increase in income.

4. Assumptions for Short-Run Analysis

  • Constant final goods price.
  • Constant rate of interest.
  • Perfectly elastic aggregate supply at the price level.

5. Effective Demand Principle

  • Aggregate output is determined solely by aggregate demand level.
  • Changes in autonomous spending significantly impact aggregate output through the multiplier process.
 
Chapter 5 - Government Budget and Economy
Introduction
  1. Government in the Economy
      • Represents the state alongside the private sector.
      • Integral in a mixed economy.
      • Influences economic life in various ways, particularly through its budget.
2. Government Budget
2.1 Components
  • Revenues: These are the various sources from which the government earns its income. These sources include things like taxes, fees, fines, surpluses from public sector enterprises, and other receipts from services offered by the government.
  • Expenditures: These are the various avenues where the government spends its income. This includes expenditure on public services, the payment of debts, investments in infrastructure, social programs, and defense, among others.
2.2 Functions
  • Regulation of economic activities: The government uses its budget to control various economic activities. It may provide subsidies, grants, and relief programs, or impose duties, taxes, and fines to regulate economic activities.
  • Redistributing income: Through its fiscal policy, the government can work to ensure a more equitable distribution of income. This might involve higher taxation for the wealthy and more support or services for those in need.
  • Allocating resources: The government can directly influence the allocation of resources in the economy by setting spending priorities and making investments.
  • Managing public enterprises: Income and expenditure related to public sector enterprises are also part of the government budget.
  • Influencing macroeconomic aggregate variables: Through its budget, the government can influence macroeconomic variables like aggregate demand, income, and employment levels.
3. Budget Types
3.1 Balanced Budget
  • This type of budget is achieved when total government revenues are equal to total government expenditures. There is no deficit or surplus in a balanced budget.
3.2 Surplus Budget
  • A surplus budget occurs when total revenues exceed total expenditures. The government can use the surplus funds in various ways, such as paying off debt, investing in future projects, or saving for a rainy day.
3.3 Deficit Budget
  • A deficit occurs when total expenditures exceed total revenues. This means the government is spending more than it earns, which is often funded through borrowing or drawing upon reserves, leading to public debt.

4. Budget Deficits

  • Implications: Can stimulate economic activity but may lead to debt.
  • Measures to Contain: Reducing expenditures, increasing taxes, and promoting economic growth.

5. Fiscal Policy and Multiplier (Box 5.1)

  • Fiscal Policy: The government adjusts its spending levels and tax rates to monitor and influence a nation's economy.
  • Multiplier Effect: An initial change in aggregate demand causes a more significant final impact on output and employment.

6. Government Debt

  • Accumulates due to repeated deficits.
  • Implications: Can finance investments but may crowd out private investment and lead to higher long-term interest rates.
Government Budgets- Meaning and its Components
1. Government Budget in India
  • 1.1 Definition & Time Frame
    • Mandated by Article 112 of the Indian Constitution.
    • Involves a statement of the estimated receipts and expenditures of the government for every financial year (April 1 to March 31).
    • Known as the 'Annual Financial Statement.'
  • 1.2 Impact
    • Though it pertains to one financial year, its effects extend beyond, necessitating a distinction between revenue account (current financial year) and capital account (assets and liabilities).
2. Objectives of Government Budget
  • 2.1 Allocation Function
    • Provision of public goods (e.g., national defense, roads) that aren't feasible through individual market transactions.
    • Public goods are non-rivalrous (one person's consumption doesn't prevent others') and non-excludable (benefits available to all, even those who don't pay).
  • 2.2 Redistribution Function
    • Involves the transfer of income and wealth for a fairer distribution.
    • Achieved through taxation, subsidies, and welfare expenditures.
  • 2.3 Stabilization Function
    • Addresses the volatility in the economy by regulating aggregate demand.
    • Involves corrective measures during inflation (excess demand) and deflation/unemployment (insufficient demand).
3. Classification of Receipts
  • 3.1 Revenue Receipts
    • Non-redeemable; comprises tax revenues (direct and indirect taxes) and non-tax revenues (interest receipts, dividends, profits, grants-in-aid).
  • 3.2 Capital Receipts
    • Create liabilities or reduce financial assets; including loans and disinvestments.
4. Classification of Expenditure
  • 4.1 Revenue Expenditure
    • Doesn't result in asset creation; includes expenses for government functioning, interest payments, grants, etc.
  • 4.2 Capital Expenditure
    • This leads to asset creation or reduction in liabilities; including spending on infrastructure, loans by the government, etc.
5. Policy Statements (Mandated by FRBMA)
  • 5.1 Medium-term Fiscal Policy Statement
    • Sets a three-year rolling target for fiscal indicators, ensuring sustainable financing.
  • 5.2 Fiscal Policy Strategy Statement
    • Outlines the government's fiscal strategy, justifying deviations from fiscal measures.
  • 5.3 Macroeconomic Framework Statement
    • Assesses economic prospects concerning GDP growth, fiscal balance, and external balance.
Balanced, Surplus and Deficit Budget
1. Types of Budgets: 1.1. Balanced Budget: Government expenditure equals revenue. 1.2. Surplus Budget: Revenue exceeds expenditure. 1.3. Deficit Budget: Expenditure exceeds revenue.
2. Government Deficits: 2.1. Revenue Deficit: Revenue expenditure exceeds revenue receipts. 2.2. Fiscal Deficit: Total expenditure exceeds total receipts excluding borrowings. 2.3. Primary Deficit: Fiscal deficit minus interest payments.
3. Fiscal Policy: 3.1. Purpose: Stabilize output, employment, and general economic conditions. 3.2. Tools: - Government Spending: Directly increases aggregate demand. - Taxes and Transfers: Affect disposable income, influencing consumption and saving. 3.3. Effects: - Spending Multiplier: Increased government spending raises aggregate demand and output. - Tax Multiplier: Tax cuts increase disposable income, boosting consumption and output.
4. Debt and Deficit Perspectives: 4.1. Government Debt: - Accumulated deficits lead to debt. - Interest on debt adds to government expenditure. 4.2. Debt Considerations: - Inter-generational Equity: Current borrowing could burden future generations. - Ricardian Equivalence: Suggests borrowing and taxation are equivalent; consumers anticipate future taxes. - Debt to Foreigners: Requires sending goods/services abroad for interest payments. 4.3. Deficit Criticisms: - Inflationary Potential: Increased spending or tax cuts boost demand, potentially causing inflation. - Crowding Out: Government borrowing might reduce private sector investment. - Effect on Savings: Deficits may reduce national savings, but can also stimulate income and thus savings. 4.4. Investment in Infrastructure: Can benefit future generations if it leads to higher economic growth.
notion image
5. Deficit Reduction Strategies: 5.1. Increasing Taxes: Preferably direct taxes; indirect taxes are regressive. 5.2. Reducing Expenditure: This can be achieved through efficiency, planning, and potentially reducing the scope of government activities. 5.3. Privatization: Raising receipts through the sale of shares in Public Sector Undertakings (PSUs). 5.4. Effects on the Economy: Cutting vital programs can have negative consequences.
6. Fiscal Responsibility and Budget Management Act (FRBMA):
  • Self-imposed constraints to avoid excessive deficits.
  • Deficits can vary with economic conditions, independent of fiscal policy changes.
Additional Concepts
1. Key Concepts:
  • 1.1 Marginal Propensity to Consume (MPC): The portion of additional income that an individual consumes.
  • 1.2 Government Expenditure Multiplier: Indicates the effect of government spending on income. Higher MPC leads to a larger multiplier.
  • 1.3 Tax Multiplier: Reflects the change in aggregate income due to changes in taxes. It's smaller than the government expenditure multiplier.
2. Balanced Budget Multiplier:
  • 2.1 Concept: When a government spending increase is matched by an equal tax increase, the output rises by the same amount as the spending increase.
  • 2.2 Calculation: It's always equal to one, indicating that income rises by the exact amount of increased government spending, despite tax increases.
3. Proportional Taxes:
  • 3.1 Impact on Consumption: Proportional taxes reduce consumption at each income level and lower the slope of the consumption function.
  • 3.2 Effect on Multiplier: The presence of proportional taxes reduces the value of the government expenditure multiplier.
4. Fiscal Policy Instruments:
  • 4.1 Usage: This can be adjusted to offset undesirable shifts in investment demand.
  • 4.2 Automatic Stabilizers: Proportional taxes and welfare transfers stabilize the economy against fluctuations without discretionary intervention.
5. Government Debt:
  • 5.1 Financing: Through taxation, borrowing, or printing money.
  • 5.2 Burden: Transfers reduced consumption to future generations, potentially affecting national savings and capital formation.
  • 5.3 Ricardian Equivalence: Suggests consumers foresee future taxes due to current borrowing, leading to increased current savings and offsetting government dissaving.
6. Deficits and Inflation:
  • 6.1 Potential Cause of Inflation: Increased government spending or reduced taxes boost aggregate demand, potentially causing inflation if output can't increase proportionately.
  • 6.2 Crowding Out Effect: Government borrowing might reduce private investment, though this effect can be mitigated if the deficit-financed spending boosts income and savings.
7. Deficit Reduction Strategies:
  • 7.1 Taxation: Increasing tax revenue, especially from direct taxes.
  • 7.2 Expenditure Reduction: Through efficiency improvements or cuts in government programs.
  • 7.3 Disinvestment: Raising receipts through the sale of shares in Public Sector Undertakings (PSUs).
8. Perspectives on Government Debt:
  • 8.1 Traditional View: Debt is a burden due to future taxes and potential reduction in investment and growth.
  • 8.2 Alternative View: Debt is not necessarily burdensome if it leads to investments that spur growth or if it's largely owed domestically.
