Study Notes

Introduction to Economics

Economics is the study of how societies allocate scarce resources to satisfy unlimited wants.
Scarcity arises because resources are limited while human needs and wants are unlimited.
This necessitates choices about how resources are used.

Outline

Basic Economic Problem of Scarcity: Humans have infinite needs and wants, but finite resources.
Types of Economies: Different economic systems (e.g., market, mixed, command) exist.
Specialisation and Division of Labour: Breaking down production into specialized tasks increases efficiency and output.
Economics as a Social Science: Uses scientific methods to study human behaviour in the economy.
Production Possibility Frontiers Model (PPF): Illustrates the trade-offs inherent in using scarce resources.

Basic Economic Problem: Scarcity

Resources are limited (e.g., land, labor, capital, entrepreneurship);
Four Factors of Production:
- Land (all natural resources)
- Labor (human effort)
- Capital (man-made resources)
- Entrepreneurship (organizing the other three)
Wants are unlimited.
Needs are limited.

Basic Economic Problem: Scarcity - continued

Choices must be made about how to allocate scarce resources.
Opportunity cost: The value of the next best alternative forgone when a choice is made.
Economic goods: Goods that are scarce and have opportunity costs.
Free goods: Goods that are abundant and have no opportunity costs.
The three basic economic questions societies face are:
- What goods and services should be produced?
- How should goods and services be produced?
- For whom should goods and services be produced?

3 Types of Economic Systems

Market economies: Buyers and sellers interact to allocate resources via prices.
Central planning/command economies: A central authority (usually the government) allocates resources.
Mixed economies: Combine elements of markets and central planning to allocate resources.

3 Types of Economic Systems - continued

Free market economies: Resources primarily allocated through markets; minimal govt intervention.
Mixed economies (e.g., Western Europe): Significant government intervention, but markets dominate.
Command economies (e.g., Cuba): Government control of resource allocation; little reliance on markets.

Evaluating the 3 types of Economic Systems

Choice: Free market economies tend to offer more choice in goods and services; command economies less so.
Quality and innovation: Free market economies generally lead to higher quality and innovation due to competition.
Efficiency: Free market economies generally are more efficient in resource use compared to mixed or command economies.
Economic growth: Evidence suggests little difference in economic growth rates across free market, mixed, and command economies.
Distribution of wealth and income: Free market economies tend to have more income inequality; Mixed or command tend to reduce this inequality through redistribution of income.
Risk: Free market economies often leave citizens more vulnerable to economic downturns; mixed & command provide more safety nets.
Political freedom: Free market economies usually allow more political freedom than command economies.

Famous Economists

Adam Smith: Father of Classical economics; advocated for free markets and the "invisible hand."
Karl Marx: Criticized capitalist economies, arguing for a socialist system.
Friedrich Hayek: Argued against government intervention in economies; focused on individual freedom.

Specialization

Specialization is breaking down production into smaller, more specialized tasks.
It increases productivity.
Countries and businesses can specialize in production to increase levels of efficiency.
Globalizes trade and competition.

Division of Labour

Division of labour is dividing work into specialised tasks performed by different people.
Increased productivity and efficiency.
Workers become more skilled and proficient in their specific tasks.
Costs can include monotonous work, decreased job satisfaction and difficulties in switching roles.

Markets and Money

Markets are mechanisms for facilitating exchange of goods and services.
Markets operate based on supply and demand where prices reflect scarcity and value.
Money is anything generally accepted as a medium of exchange and payment.
It eliminates the need for a "double coincidence of wants" in bartering.

4 Functions of Money

Medium of exchange
Measure of value
Store of value
Method of deferred payment

5 Types of Money

Cash (coins and banknotes)
Current Accounts & Bank Deposits
Near Monies (e.g., checks, savings accounts)
Non-money financial assets (e.g., houses, stocks)
Money substitutes (e.g., credit cards)

Financial Markets

Facilitate savings, lending, exchange, and risk management.
Financial markets include stock, bond, and foreign exchange markets.
Trading financial instruments allows for investment, lending, and risk mitigation.

Economics seeks to explain how economic agents (individuals, firms, etc.) make decisions under scarcity.
The scientific method is used to develop and test economic theories and models, although it has limitations.

Problems with Using the Scientific Method in Economics

Difficulty controlling experiments due to shifting economic variables.
Economic variables are difficult to isolate for analysis.
Human behaviour is complex and unpredictable.

Simplifications and Assumptions in Economics

Assumptions (like 'all other things being equal') are essential to simplify models and improve analysis.
Economic models/theories often focus on the most significant variables to avoid overcomplication.

2 Approaches to Economics

Positive economics: Objective statements that can be verified (e.g., unemployment rate).
Normative economics: Subjective statements reflecting values and beliefs (e.g., healthcare should be free).

Production Possibility Frontiers (PPFs)

PPF diagrams show all possible combinations of two goods an economy can produce given its resources and technology.
Points on the frontier are efficient (maximizing output).
Points inside the frontier are inefficient (resources not fully used).
Points outside the frontier are unattainable (given current resources).
PPFs illustrate trade-offs and opportunity costs.

PPF and Scarcity

Only combinations within or on the PPF frontier are feasible.
Combinations outside of the frontier are not feasible.
The economy's current resource and technology levels determine the achievable combinations of goods.

PPF and Opportunity Costs

Moving along the PPF, producing more of one good involves producing less of another.
The opportunity cost represents the lost production of the other good.
The gradient of the PPF reflects the opportunity cost of producing one good in terms of the other.
Concave PPF: Opportunity costs increase as production of the good increases further.
Linear PPF: Constant opportunity costs.

PPF and Economic Growth and Decline

Economic growth leads to a shift of the PPF outwards, expands production possibilities.
Economic decline leads to a shift of the PPF inwards, contracts production possibilities.
Change in productive capacity can result from changes in resources, technology, or factors of production

Sustained Economic Growth

Requires investments in capital goods, to expand output possibilities in the future.
Trade-offs exist between present consumption and future output increases.

PPF, Efficiency, and Choice

Productive efficiency: The economy fully utilizes its resources; points are on the PPF.
Allocative efficiency: The economy produces goods/services according to society's preferences (points on the PPF which best reflect society's needs).
