Economics
Economy
Definition: Economy is derived from the Greek words "oikos" meaning house and "nomos" meaning manage. It refers to the management of a household based on principles of allocating resources.
Economics as a Social Science
Definition: Economics is a social science that studies society and the relationships of individuals within a society. It incorporates elements from sociology, psychology, political science, and elements of history. It's considered a soft science due to its reliance on generalizations and the human factor.
Needs vs. Wants
Definition: The central purpose of economic activity is to produce goods and services to satisfy people’s needs. Needs are essential for survival and include things like food with sufficient nutrients. Wants, on the other hand, are desirable but not essential for survival, like books or chocolate.
Types of Resources
Definition: Natural resources, human-made resources, human resources.
Scarcity
Definition: Scarcity arises due to limited resources and the fundamental economic problem is that both goods and the resources needed to produce them are scarce.
Environmental Resources
Definition: Environmental resources encompass all natural resources used or potentially useful in an economic system. These include physical resources like soil, water, forests, and minerals, as well as abstract resources like clean air, solar and wind energy.
Renewable Resources
Definition: Renewable resources can be reproduced and perpetually maintained. Examples include forests, animals, and water. However, their availability depends on human management.
Non-renewable Resources
Definition: Non-renewable resources cannot be easily regenerated or their regeneration is very slow. Examples include oil, gas, and minerals.
Fundamental Economic Problem
Definition: The fundamental economic problem arises because both goods and the resources needed to produce them are scarce.
Opportunity Cost
Definition: Opportunity cost refers to the value of the next best alternative that must be forgone when a choice is made. It's the measure of alternatives that have to be given up.
Rational Behavior
Definition: Economists generally assume that people behave rationally, meaning they try to make decisions that maximize their private benefit or self-interest.
Production Possibility Frontier (PPF)
Definition: PPF illustrates the different combinations of two products that can be produced given all available resources are being fully utilized.
Comparative Advantage
Definition: Determines specialization and trade. Countries have different opportunity costs to produce goods, and will tend to specialize in goods that they have lower opportunity costs in.
Commerce
Definition: Trade between states or nations. Allows for the exchange of needed/desired goods and services between countries.
Exports/Imports
Definition: Goods and services sold to one country from another. Goods and services bought by one country from another.
Trade Deficit/Surplus
Definition: Deficit - country buys more goods than they sell. Surplus - sells more goods than it imports. Some countries have trade agreements that have reduced barriers to increase trade between them (EU, NAFTA…).
Gross Domestic Product (GDP)
Definition: GDP is the monetary value of all finished goods and services produced within a country's borders in a specific time period.
GDP Calculation
Definition: GDP can be calculated by adding up all of the money spent by consumers, businesses, and the government in a given period. It may also be calculated by adding up all of the money received by all the participants in the economy. In either case, the number is an estimate of "nominal GDP." We are using: The formula for GDP is: GDP = C + I + G + (X-M). C is consumer spending, I is business investment, G is government spending, and (X-M) is net exports. X = exports; M = imports. GDP Per Capita is a measurement of the approximate value of a country's gross domestic product (GDP) contributed by each member of its population. It is calculated by taking a country's GDP and dividing it by the country's population.
Government Budget
Definition: A government budget is an annual statement of the estimated receipts and estimated expenditure of a government during one financial/fiscal year.
Objectives of government budgets:
- Reallocation of wealth
- Reduction of inequalities in income and wealth
- Economic stability (people have the resources essential to a healthy life)
- Management of public enterprises
- To achieve economic growth
Components of Government Budgets- receipts:
- Revenue Receipts: Money received by the government for its operations. Types: Taxes, Non-tax revenues (e.g., loans to states, dividends from public sector companies)
- Capital Receipts: Money raised by the government for capital investment. Sources: Sale of bonds and securities, Borrowings from Central Bank and financial institutions, Loans and aids from foreign countries and international organizations
Components of government budgets- expenditure
- Expenditure: How the government allocates its funds. Categories: Revenue Expenditure, Capital Expenditure
- Revenue Expenditure: Government spending that doesn't create assets or reduce liability. Examples: Salaries of government employees, Interest payments on government loans, Pensions, subsidies, grants
- Capital Expenditure: Government spending that leads to the creation of assets and reduction in liabilities. Examples: Construction of buildings, roads, bridges
Direct vs. Indirect Taxes
Definition: Direct taxes are paid directly by individuals or companies (e.g., income tax), based on income wealth and profit, while indirect taxes are paid by a third party but ultimately passed on to the consumer through the price of goods or services (e.g., VAT).
Flat Tax
Definition: A flat tax is a system where everyone pays the same percentage of their income in taxes, regardless of their income level.
- Progressivity:
- Regressive - lower-income individuals pay a higher proportion of their income compared to higher-income individuals.
- Simplicity:
- Simple to administer and calculate.
- Example:
- A country may have a flat tax rate of 15%, meaning everyone, regardless of income, pays 15% of their earnings in taxes.
Direct Tax
Definition: A direct tax is a tax imposed directly on individuals or businesses, and the taxpayer is responsible for paying it directly to the government.
- Progressivity:
- Can be progressive (tax rate increases with income) or proportional (same percentage for all income levels).
- Complexity:
- Can be more complex to administer due to various tax brackets and exemptions.
- Example:
- Income tax is a common example of a direct tax, where individuals pay a percentage of their income to the government based on a progressive tax rate.
Microeconomics vs. Macroeconomics
Definition: Microeconomics studies individual and business decisions, while macroeconomics analyzes decisions made by countries and governments. Microeconomics is bottom-up, focusing on supply and demand, while macroeconomics is top-down, examining the economy as a whole.
Eurosystem
Definition: The Eurosystem is composed of the European Central Bank (ECB) and the national central banks of the Eurozone countries. It is responsible for maintaining price stability and safeguarding the value of the Euro.
Functions of ECB
Details: The ECB has several functions, including defining and implementing monetary policy, conducting foreign exchange operations, managing official foreign reserves, and promoting the smooth operation of payment systems, like SEPA.
Monetary Policy Instruments
Details: The central
bank uses various instruments for monetary policy, such as adjusting interest rates, conducting foreign exchange operations, and setting currency reserve responsibilities for national central banks.
Supply + demand
Supply refers to how much of a certain good or service is available for
people to purchase. Quantity supplied is the amount offered for sale at a particular price.
Demand refers to how many people wish to buy a certain good or service. Quantity
demanded is the demand at a particular price, it is represented as the demand curve.
The main determinant of supply / demand is the price of the product.
Demand Schedule
Definition: A demand schedule is a table listing quantities of a product or service that consumers are willing to buy at different prices. It can be represented graphically.
Law of Supply
Definition: The Law of Supply states that, other things being equal, as the price of a good increases, the quantity supplied will also increase. This implies a positive relationship between price and quantity supplied.
Equilibrium in Economics
Definition: Equilibrium in economics is the point where the quantity demanded equals the quantity supplied. It's the price at which buyers are willing to purchase exactly matches what producers are willing to sell.
Demand Curves and Changes in Demand
Details: Demand Curves can shift due to factors such as changes in the number of consumers, changes in consumers' income, shifts in preferences or popularity, changes in expectations about the future, and the availability of substitute or complementary goods.
Types of Taxes Today
Details: Types of taxes include income tax (a percentage of income), corporation tax (a percentage of a firm’s profit), sales tax/VAT (an indirect tax on goods), excise duties (taxes on specific goods or services like alcohol and tobacco), and production taxes on particular goods or services.
Higher taxes also mean people have less money to spend, so businesses make less profit, which can be bad for jobs and wages. Lower profits also mean they pay less tax too.
Government Debt
Details: Government debt is the total amount of money owed by the government that has accumulated over time. It rises in years when there is a budget deficit and falls in years when there is a surplus.
Governments often choose to borrow to boost the economy if it looks like it might be at risk of slowing down.
Governments also borrow to fund major long-term projects such as new railways and roads, which it also hopes will help the economy to grow.
The larger the national debt gets, the more interest the government has to pay. (This might be more than the government spends on education!)
Some economists fear the government is borrowing too much, at too great a cost.
Others argue extra borrowing helps the economy grow faster - generating more tax revenue in the long run.
Where do governments borrow money?
- from each other
- from global organizations like the World Bank and the International Monetary Fund (IMF)
- from individuals, pension funds and insurance companies (bonds)

Taxes in History
Details: About 5,000 years ago, taxation was first recorded in ancient Egypt, where the Pharaoh collected a tax equivalent to 20 percent of all grain harvests. The Greeks later spread the idea of taxation throughout the developed world.
Types of Taxes
Details: Taxes include income tax (a percentage of income), corporation tax (a percentage of a firm’s profit), sales tax/VAT (an indirect tax on goods), excise duties (taxes on specific goods or services like alcohol and tobacco), and production taxes on particular goods or services.
Market
A market is a means by which the exchange of goods and services takes place as a result of buyers and sellers being in contact with one another.
Markets are places in which things are bought and sold. In Economics and Business, however, the market is not a place; it has expanded to include the whole geographical area in which sellers compete with each other for customers.
B2B and B2C markets (Business-to-business / business-to-consumer)
Market Structures
Details: Market structures include Monopoly (one firm, unique product), Oligopoly (a few large firms, standardized or differentiated products), Monopolistic Competition (many firms, differentiated products), and Perfect Competition (many producers and consumers, homogeneous products).
Monopoly
Definition:
Market structure characterized by a single firm, offering a unique product, and blocking market entry.
Features:
Market power (acts as a price maker)
Examples: Local utilities (e.g., Google, Microsoft, Telecommunications, Postal services, Railway)
Oligopoly
Definition:
Market structure with a few large firms offering either standardized or differentiated products, and significant barriers to entry.
Features:
Market power (interdependent with other firms)
Examples: Industries like steel, oil, automobiles (e.g., Nestle, P&G, Johnson & Johnson)
Perfect Competition
Definition:
Market structure with many producers and consumers, no individual entity can influence market supply or demand. Homogeneous products with perfect substitution.
