Economic Issues and Concepts

Introduction

This chapter introduces the foundational concepts of microeconomics, focusing on the nature of economic problems, the role of scarcity and choice, opportunity cost, and the structure of modern economies. It also explores different economic systems and the role of government in addressing economic issues.

1.1 What Is Economics?

Definition and Scope

Economics is the study of the use of scarce resources to satisfy unlimited human wants.
Resources are limited, but human desires are virtually infinite, creating the need for choice and prioritization.

Factors of Production

Land: Natural endowments (e.g., minerals, forests, water).
Labour: Mental and physical human effort used in production.
Capital: Tools, machinery, and equipment used to produce goods and services.

These resources are collectively called factors of production.

Goods, Services, Production, and Consumption

Goods: Tangible products (e.g., cars, steel).
Services: Intangible products (e.g., legal advice).
Production: The act of making goods and services.
Consumption: The act of using goods and services.

Scarcity and Choice

Resources are scarce relative to human wants.
Scarcity necessitates choice—not all wants can be satisfied.

Opportunity Cost

Making choices involves opportunity cost: the value of the next best alternative forgone when a choice is made.
Formula:
Example: If $12 million/km) or new bike paths ( million/km), the opportunity cost of $1 km of new bike paths, and vice versa.

Budget Line and Attainability

Points on or inside the budget line are attainable given current resources.
Points outside the budget line are unattainable.

Production Possibilities Boundary (PPB)

The PPB illustrates scarcity, choice, and opportunity cost.
Points on the PPB are efficient and attainable; points inside are inefficient; points outside are unattainable.
Example: Moving from one point to another on the PPB involves a trade-off, reflecting opportunity cost.

Four Key Economic Problems

1. What Is Produced and How?

Resource allocation determines what goods and services are produced and in what quantities.
Questions arise about the optimal combination of goods and the role of government intervention.

2. What Is Consumed and by Whom?

Distribution of output among individuals is a central concern.
Equity and fairness in consumption may require government intervention.

3. Why Are Resources Sometimes Idle?

Idle resources mean the economy is operating inside its PPB.
Possible causes include market failures, cyclical unemployment, or necessary adjustments.

4. Is Productive Capacity Growing?

Economic growth shifts the PPB outward, allowing more production of all goods.
Growth is essential for improving living standards over time.

Microeconomics and Macroeconomics

Microeconomics: Studies the determination of prices and quantities of specific products and factors of production (problems 1 and 2).
Macroeconomics: Studies economic aggregates such as total output, employment, and growth (problems 3 and 4).

Economics and Government Policy

Government policies can address all four key economic problems by:
- Correcting market failures (misallocation of resources).
- Addressing fairness in distribution.
- Reducing idleness of resources.
- Promoting economic growth.

1.2 The Complexity of Modern Economies

The Nature of Market Economies

Self-Organizing: When individuals act in their own self-interest, the market coordinates their actions efficiently.
Efficiency: Resources are allocated to produce what people want with the least possible waste.
Adam Smith: Emphasized that self-interest, not benevolence, drives economic activity and coordination.

Incentives and Self-Interest

Individuals respond to incentives and generally pursue their own self-interest.
Sellers supply more when prices are high; buyers demand more when prices are low.
Other motivations (e.g., ethical values) can also influence decisions.

The Decision Makers

Consumers: Decide what to buy and how much.
Producers: Decide what to produce and for whom.
Government: Decides how to allocate resources for public benefit.

The Circular Flow of Income and Expenditure

Goods and services flow from producers to consumers.
Payments for goods and services flow from consumers to producers.

Production and Trade

Specialization of labour: Workers focus on specific tasks, increasing efficiency.
Division of labour: Production is broken into specialized tasks.
Money: Facilitates trade by eliminating the need for barter, enabling greater specialization.

Globalization

Refers to the increased importance of international trade.
Driven by reduced transportation costs and advances in information technology.
Brings challenges such as human rights, environmental, and production standards.

1.3 Is There an Alternative to the Market Economy?

Types of Economic Systems

Traditional: Decisions based on customs and traditions.
Command: Central authority makes economic decisions.
Free-Market: Decisions made by individuals and firms in markets.
Most economies are mixed economies, combining elements of all three systems.

The Great Debate: Market vs. Command Economies

Karl Marx: Advocated for central planning to ensure just distribution.
Socialist/communist systems often failed to achieve higher living standards compared to free-market economies.
Most countries have shifted towards freer markets.

Government in the Modern Mixed Economy

Governments provide key institutions (private property, freedom of contract).
Intervene to correct market failures, provide public goods, and address externalities.
Government policy can sometimes improve societal outcomes.

Economics and Other Social Sciences

Economics is interconnected with politics, history, philosophy, law, and sociology.
Understanding economic issues often requires insights from other social sciences.
