    Study Notes

    National Income

    • National income is the total value of all goods and services produced in a country during a year
    • It is measured using money, and reflects the combined value of all goods and services produced
    • Paul A Samuelson defines it as the final result of applying money to measure diverse goods and services produced

    Gross Domestic Product (GDP)

    • GDP is the total market value of all final goods and services produced within a country's borders
    • GDP is calculated using the formula GDP=C+G+I+(X-M)
      • C = consumption expenditure
      • I = Investment
      • G = Government expenditure
      • X = Exports
      • M = Imports

    Gross National Product (GNP)

    • GNP is the total value of all finished goods and services produced by the citizens of a country, regardless of location
    • It only calculates the final or finished goods
    • Calculated using GNP = C + I + G + X + NFIA
      • C = Consumption
      • I = Investment
      • G = Government
      • X = Net exports
      • NFIA = Net factor income from abroad

    Net National Product (NNP)

    • NNP is the total value of goods and services produced in a country minus depreciation
    • Represents the value of goods and services available for consumption and investment after accounting for wear and tear on capital

    Nominal GDP

    • The total value of goods and services produced in a country using current prices
    • Does not adjust for inflation, meaning it can be inaccurate when comparing output over time

    Real GDP

    • Real GDP is adjusted for inflation, reflecting the value of goods and services produced at constant prices

    Business Cycle

    • An economic cycle described as a fluctuation in economic activity around a long-term growth trend
    • Includes four phases: peak, contraction, trough, and expansion

    Peak

    • The point in the cycle where growth hits its maximum rate
    • Prices and economic indicators may stabilize briefly before reversing downward
    • Businesses may re-evaluate budgets and spending as imbalances emerge

    Contraction

    • Growth slows, employment falls, and prices stagnate
    • Supply may exceed demand, leading to market saturation and price declines
    • Can lead to a recession, potentially escalating to a depression

    Trough

    • The low point of the cycle, marked by bottoming supply and demand
    • Represents a period of hardship with negative impacts on spending and income
    • Provides an opportunity for individuals and businesses to restructure their finances

    Effects of the Business Cycle

    Expansion Phase

    • Economic Growth: Increased economic activity, higher GDP, higher production of goods and services, strong consumer demand
    • Employment: Robust job creation, lower unemployment, rising wages due to tight labor markets
    • Investment: Businesses invest in new projects, capital, and infrastructure
    • Inflation: Increased demand may lead to moderate inflation
    • Consumer Confidence: High consumer and business confidence fuels spending and investment

    Peak

    • Overheating: Demand exceeding supply leading to excessive inflation
    • Tight Labor Markets: Low unemployment leading to wage inflation
    • Interest Rates: Central banks may raise rates to control inflation

    Contraction (Recession) Phase

    • Economic Decline: GDP growth slows or becomes negative, overall economic activity decreases
    • Unemployment: Businesses cut production and lay off workers, leading to higher unemployment rates
    • Decreased Consumer Spending: Due to unemployment and uncertainty, consumer spending falls
    • Falling Investment: Businesses become pessimistic about future demand, resulting in decreased investment
    • Deflationary Pressures: Prices may fall, particularly during severe and prolonged recessions
    • Government Intervention: Governments may increase spending and cut taxes to stimulate the economy, while central banks may lower interest rates

    Trough

    • Lowest Economic Activity: GDP, employment, and investment are at their weakest
    • Stabilization: The contraction ends, paving the way for recovery
    • Policy Response: Fiscal and monetary policies from the downturn begin to take effect, aiding recovery
    • Measure to Control Business Cycle: Preventive measures and Curative measures are implemented to mitigate fluctuations

    Monetary Policy

    • Interest Rates: Central banks adjust interest rates to cool inflation (rising rates) or stimulate spending (lower rates)
    • Open Market Operations: Buying or selling government securities to adjust the money supply
    • Quantitative Easing: Injecting liquidity into the economy when traditional monetary tools are insufficient
    • Reserve Requirements: Adjusting the amount of reserves banks must hold to influence lending

    Fiscal Policy

    • Government Spending: Increasing spending during downturns to boost demand, reducing it during booms to prevent overheating
    • Taxation: Cutting taxes to stimulate the economy during downturns, raising taxes to cool economic growth during booms
    • Automatic Stabilizers: Built-in mechanisms (progressive taxes, unemployment benefits) that automatically respond to economic changes

    Inflation

    • Rate at which prices for goods and services rise, leading to a decrease in the purchasing power of money
    • A moderate level of inflation is normal in a growing economy, but excessive levels can have negative effects

    Types of Inflation

    • Demand-Pull Effect: Increase in the supply of money and credit leads to higher demand, which outpaces production capacity, resulting in higher prices
    • Cost-Push Effect: Increase in production input costs leads to higher prices. This occurs when money supply is channeled into commodity or asset markets
    • Built-In Inflation: People expect inflation to continue, leading to demands for higher wages and costs, further increasing prices

    Inflation Measures

    • Consumer Price Index (CPI): Measures average changes in prices paid by consumers for consumer goods and services
    • Producer Price Index (PPI): Measures average changes in selling prices received by domestic producers
    • Wholesale Price Index (WPI): Measures average changes in prices of goods at the wholesale level

    Weimar Republic Hyperinflation

    • Post-World War I: Severe economic hardship in Germany due to war losses and reparation payments
    • Economic Instability: Reparation payments strained the weakened economy, leading to increased money printing
    • Runaway Inflation: Prices doubled every few days, currency became worthless

    Exchange Rate

    • The rate at which one currency can be exchanged for another
    • Determines the value of different currencies in relation to each other
    • Impacts trade and capital flow dynamics

    Exchange Rate Regimes

    • Floating: The currency floats freely
    • Fixed: The exchange rate is fixed to a base currency, like the US dollar
    • Pegged: Currency's value is linked to another currency or basket of currencies
