Study Notes
Gross Domestic Product (GDP)
- GDP measures the market value of all final goods and services produced within a country in a given period of time.
- GDP is a measure of a nation's total income.
- GDP is the most closely watched economic statistic because it is thought to be the best measure of a society's economic well-being.
- Income must equal expenditure for the economy as a whole.
- GDP can be calculated using the following formula:
- Y = C + I + G + NX
- Y: GDP
- C: Consumption
- I: Investment
- G: Government purchases
- NX: Net Exports
Consumption
- Spending by households on goods/services, with the exception of purchasing new housing
Investment
- Spending on capital equipment, inventories, and structures, including household purchases of new housing
Government Purchases
- Spending on goods and services by municipal, territorial, provincial, and federal government.
Net Exports
- Value of a nation's exports minus the value of imports (also called trade balance)
Nominal vs. Real GDP
- Nominal GDP: The production of goods and services valued at current prices.
- Real GDP: The production of goods and services valued at constant prices.
Consumer Price Index (CPI)
- Measures the overall cost of the goods and services bought by a typical consumer.
- CPI is the most commonly used measure of the cost of living.
- The CPI overstates the cost of living by 0.5% per year due to various factors such as substitution bias, quality bias and new product bias.
GDP Deflator vs. CPI
- GDP Deflator is a broader measure of price level than the CPI.
- CPI measures the average price of a basket of goods and services consumed by urban consumers.
- GDP Deflator measures the average price of all goods and services produced in the economy.
Real vs Nominal
- Real Interest Rate: Interest reported taking into account inflation.
- Nominal Interest Rate: Interest rate not adjusted for inflation.
Economic Growth
- Measured by the percentage change in real GDP.
- Measured over a period of time.
- Productivity is a key driver of economic growth.
- Productivity is defined as the quantity of goods and services produced from each hour of a worker's time.
Factors that Influence Productivity Growth
- Physical Capital : Increase in the quantity of physical capital per worker results in higher productivity.
- Human Capital: Increase in the average level of education and training (human capital) in the workforce results in higher productivity.
- Natural Resources: An increase in the quantity of natural resources per worker can lead to higher productivity.
- Technological Knowledge: An increase in the quantity of technological knowledge (human capital) in the workforce results in higher productivity.
The Importance of Saving, Investment, and Stable Financial Markets
- A well-functioning financial system can help channel funds from savers to borrowers, leading to higher investment and economic growth.
Diminishing Returns and the Catch-Up Effect
- Diminishing returns to capital imply that as a country's capital stock increases, the extra output produced from each additional unit of capital will eventually decrease.
- The catch-up effect suggests that poor countries may have the potential to grow more quickly than rich countries due to the diminishing returns to capital.
Foreign Investment
- Investment by foreigners in a country. It can help increase productivity by increasing the supply of capital and improving access to new technologies.
Education and its Impact on Productivity
- Education is a form of human capital that can lead to greater levels of productivity in the economy.
- Higher levels of education (human capital) result in higher productivity.
Property Rights and Political Stability
- A country with strong property rights and a stable political system is more likely to attract foreign investment and experience economic growth.
- Strong Property Rights mean that individuals are able to own and control their resources (like land, labor, and capital), as well as profit from their use. This encourages investment, innovation, and productivity because individuals have a secure claim to their assets.
- Political Stability means that the government is predictable, consistent, and not subject to sudden or violent changes. A stable political environment provides greater certainty for businesses and investors, leading to higher investment, and productivity.

Free Trade and its Impact on Growth
- Free trade allows countries to specialize in producing goods and services in which they have a comparative advantage.
- This can increase economic growth by leading to lower costs, more efficient allocation of resources, and increased innovation.
- Trade restrictions inhibit a country's economic growth.
The Role of Geography in Trade
- A country's geography can impact its ability to trade, e.g. a landlocked country may have greater difficulty trading.
Research and Development
- Research and Development is a major reason why living standards are higher today than in the past.
- Government research, subsidies, and tax breaks can benefit businesses and increase their investment in research, leading to improvements in technology and increased productivity.
- Investments in Research and Development can lead to the creation of new products, processes and ideas that may lead to higher productivity.
Population Growth and its Impact on Output
- Population growth can have a positive impact on output.
- A larger population means there are more workers available and so there are more workers to produce, which can increase output.
Financial System
- The financial system is a network of institutions that facilitate the transfer of funds between savers and borrowers.
- This allows for the efficient allocation of capital in an economy.
-
Two categories of institutions in the financial system:
- Financial Markets: These include the stock market, the bond market, and the foreign exchange market.
- Financial Intermediaries: These include banks, insurance companies, and mutual funds.
National Income Accounts
- The national income accounts track the flow of money in the economy.
- They provide a picture of the economy's performance.
- Y = C + I + G + NX
- This equation shows how GDP (Y) breaks down into its components: consumption (C), investment (I), government purchases (G), and net exports (NX).
Saving and Investment in National Accounts
- Saving: Represents the portion of income that is not consumed.
- Investment: Represents spending on capital goods (buildings, equipment, and inventories).
- Saving and investment are closely related in the national income accounts.
- In a closed economy (one that does not trade with other countries), saving must equal investment.
Saving and Investment in the Private and Public Sectors
-
Private Sector: Households and businesses that make up the non-governmental portion of the economy.
-
Public Sector: The government.
-
Saving: In the private sector, saving includes household saving and business saving.
-
Investment: In the private sector, investment includes spending by businesses on new capital goods, such as buildings, machinery and equipment.
-
Government Spending: Government spending is financed by taxes and borrowing.
-
Net Exports: This represents the difference between the value of exports and imports.
-
An increase in the national savings rate increases the investment rate. A higher investment rate will lead to higher GDP growth.
The Role of the Financial System in Matching Savings and Investment
- Financial markets and financial intermediaries play a crucial role in matching the saving of one person with the investment of another. This process allows for productive investment, leading to economic growth.
- Financial Markets direct funds from savers to borrowers through instruments like stocks and bonds.
- Financial Intermediaries like banks collect funds from savers and lend the funds to borrowers.
Gross Domestic Product (GDP)
- Represents the total market value of all final goods and services produced within a country during a specific period. GDP measures the total income of a nation, which is also equal to the total expenditure.
-
GDP Formula: Y = C + I + G + NX
- Y: GDP (Total output)
- C: Consumption (Spending on goods and services by households, excluding new housing)
- I: Investment (Spending on capital equipment, inventories, structures, including new housing)
- G: Government purchases (Spending on goods and services by government)
- NX: Net exports (Value of exports minus imports, also known as trade balance)
Real vs Nominal GDP
- Nominal GDP: Measured using current prices. Reflects the value of production at the prevailing prices of the period.
- Real GDP: Measured using constant prices from a base year. Represents the value of production adjusted for inflation, providing a clearer picture of actual output growth.
Consumer Price Index (CPI)
- A measure of the average change over time in the prices paid by urban consumers for a basket of consumer goods and services.
-
CPI Calculation Steps:
- Define a basket of goods and services representing a typical consumer's expenditures.
- Determine the prices of these goods and services in a base year.
- Collect price data for the same goods and services in subsequent periods.
- Calculate the cost of the basket in each period, using the prices from that period.
- Divide the cost of the basket in each period by the cost of the basket in the base year, and multiply by 100 to get the CPI.
GDP Deflator vs CPI
- Both measure price levels, but GDP deflator reflects the prices of all goods and services produced domestically, while CPI reflects the prices paid by urban consumers for a specific basket of goods and services.
Economic Growth
- Represents the increase in real GDP over time, reflecting a nation's economic progress.
- Productivity: The quantity of goods and services produced from each hour of a worker's time.
-
Factors Affecting Productivity:
- Physical Capital (K)
- Human Capital (H)
- Natural Resources (N)
- Technological Knowledge (A)
Free Trade
- Promotes economic growth by allowing countries to specialize in producing goods and services they are most efficient at and trade for other goods and services they need.
- Trade restrictions (tariffs, quotas) inhibit economic growth by limiting trade opportunities and competitiveness.
Population Growth
- Can contribute to economic growth by expanding the labor force and potentially boosting productivity through economies of scale.
- However, rapid population growth can also strain resources and infrastructure if not managed effectively, leading to slower economic growth.
Financial System
- Facilitates the flow of funds between savers and borrowers, enabling investment and economic growth.
-
Two main categories:
- Financial markets (e.g., stock market, bond market)
- Financial intermediaries (e.g., banks, mutual funds)
Saving and Investment in National Income Accounts
- National Income Accounts use the equation Y = C + I + G + NX.
- Private Sector: Savings (S) represent disposable income not spent on consumption (Y - T - C) where T is taxes.
- Public Sector: Government saving (T - G) is the difference between tax revenue and government spending.
- Savings are the source of Investment (I) in the economy.
Enhancing Economic Growth
- Diminishing Returns and the Catch-Up Effect: Countries with lower initial levels of capital tend to experience faster growth rates as they catch up to wealthier nations.
- Foreign Investment: Investments from foreign companies can boost a country's capital stock and technology, fostering economic growth.
- Education: Investing in education enhances human capital, increasing productivity and driving economic growth.
- Property Rights and Political Stability: Secure property rights and a stable political environment foster investment and economic growth.
- Research and Development: Innovation through research and development is a key driver of long-term economic growth and improvements in living standards.
