    Study Notes

    Lecture Overview

    • The lecture is about measuring the economy, specifically Gross Domestic Product (GDP).
    • The lecture will cover:
      • What GDP is
      • How GDP is measured
      • How to compare GDP across countries and over time
      • The concept of economic growth
      • GDP components (consumption, investment, government spending, net exports)
    • The lecture will use examples to illustrate concepts.
    • The lecture will outline the measurement process for different aspects of the measurement.

    Gross Domestic Product (GDP)

    • GDP is a measure of the total output of goods and services in an economy over a specific period.
    • GDP is used to estimate a country's economic output.
    • GDP accounts for a country's total output and expenditure.
    • GDP accounting is like auditing a country.
    • GDP is commonly used to compare countries' economic performance.

    Measuring GDP

    • There are three ways to calculate GDP:
      • Value added
      • Income
      • Expenditures

    GDP as Value Added

    • The sum of outputs of different sectors, subtracting the cost of goods and services used as inputs.
    • Prevents double-counting
    • Example: GDP using value added (using a simple example of a shirt economy)

    GDP as Income

    • The sum of income factors (labor and capital) including wages, profits, self-employment income, and government taxes.
    • Example: GDP as sum of profits of each industry.

    GDP as Expenditure

    • The sum of expenditures on total production in the economy.
    • Includes spending by households, firms, governments, and residents of other countries.
    • Example: GDP as expenditures.

    GDP Components

    • GDP is the sum of:
      • Consumption (C)
      • Investment (I)
      • Government Spending (G)
      • Net Exports (NX)
    • Consumption includes households' spending on goods and services (durable & non-durable).
    • Investment includes firms' & governments’ spending on new equipment, buildings, and residential dwellings, plus changes in inventories.
    • Government spending includes goods and services purchased by the government (wages, etc.)
    • Net exports = exports (X) minus imports (M).

    GDP per Capita

    • GDP per capita equals GDP divided by a country's population.
    • It is a measure of average living standards and is highly correlated with other living standards data, such as life expectancy.

    Comparing GDP across countries

    • Comparing GDP requires adjustments for price differences.
    • Purchasing power parity (PPP) is used to account for differences in the cost of living in different countries. This adjustment is done by adjusting for the different cost of living in different countries (prices).
    • The Big Mac Index measures the relative values and price differences between various countries' currencies.

    Interpreting GDP over Time

    • Nominal GDP values are based on current prices.
    • Real GDP values are adjusted for price changes (inflation).
    • Comparing real GDP values over time shows changes in the quantity of goods and services produced.

    Economic Growth

    • Economic growth is the percentage change in real GDP from one period to the next.

    GDP, Expenditures, and Recessions

    • Recessions are periods of falling output in the economy.
    • During recessions, expenditure often falls, reflecting decreased consumer spending.

    What is Not Included in GDP

    • Environmental health (air & water quality)
    • Human health & quality of life
    • Household production (home cooking, cleaning)
    • Security & Community

    Quiz

    • There was a quiz at the end of the lecture.
