Economics Quiz on Systems and Concepts

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 as a Social Science

• 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).
