Scarcity: The Fundamental Constraint of Human Desire | Economics SHS 1 SEM 1 WEEK 1 (WASSCE & NaCCA Aligned)

Section 1: Quick Summary of Key Concepts

• Economics is defined as the study of how society allocates scarce resources to satisfy unlimited wants.
• The subject is rooted in the concepts of scarcity and choice, which apply universally to every individual and nation, rich or poor.
• Microeconomics focuses on individual units (consumers, firms, specific markets), while Macroeconomics examines large-scale aggregates (GDP, national unemployment, inflation).
• Economic statements must be classified as objective, fact-based (Positive), or subjective, judgment-based (Normative).
• An Economist uses quantitative data and established theories to guide decisions regarding production, distribution, and consumption, leading to diverse and critical career paths in policy, finance, and data analysis in Ghana.

The importance of studying Economics cannot be overstated. It is the framework through which all decisions—personal, corporate, and national—are made. This first lesson introduces the foundational pillars that support the entire field, ensuring learners understand why we study choice.

Section 2: The Academic Core: The Foundation of Economic Thought

The study of economics begins not with complex equations, but with a simple, inescapable reality: Scarcity. Our desires—for better housing, faster transport, abundant food, high-quality education, and reliable power—are virtually limitless. However, the resources needed to satisfy these desires (land, labour, capital, and entrepreneurship, often called the Factors of Production) are finite and constrained. This fundamental conflict between unlimited wants and limited resources forces every individual, community, and nation to make continuous, unavoidable choices. Economics, therefore, is formally defined as the social science that studies how individuals and societies allocate scarce resources to satisfy their unlimited wants. It is fundamentally the science of choice under conditions of constraint. This definition must be internalized by every SHS student.

Defining the Economic Universe: Goods, Services, and Agents

To understand economic activity, we must define what is being exchanged within the system. Goods are tangible, physical items used to satisfy wants and needs, such as a new textbook, a locally manufactured car, or a packet of imported rice. The defining characteristic is their physicality; they can be stored and touched. Services, conversely, are intangible actions or activities that provide satisfaction, such as the act of teaching in an SHS classroom, consulting with a lawyer on a property dispute, or a professional accountant managing a company’s ledger. These valuable exchanges are facilitated by Economic Agents, which are the primary decision-makers in the economy. These agents primarily consist of Households (the primary consumers and resource owners), Firms (the primary producers of goods and services), and the Government (the regulator and provider of public goods). Understanding their interactions—how households supply resources and demand goods, and how firms utilize resources for production—is the bedrock of sophisticated market analysis.

The Division of Economic Study: Micro vs. Macro

Economics is systematically split into two distinct, yet interacting, branches based on the scope of their analysis:

1. Microeconomics (The Study of the Individual Unit)

Microeconomics focuses exclusively on the behaviour of individual economic units. This includes studying specific markets, the pricing strategies of single industries, the efficiency levels of specific firms, and detailed consumer behaviour patterns. A microeconomist typically addresses questions such as: “Why did the retail price of yam fall drastically in the Accra markets last quarter?” or “How does a single household optimize its budget when faced with rising transport costs?” Microeconomics analyses individual markets and the determination of relative prices.

2. Macroeconomics (The Study of the Aggregate Economy)

Macroeconomics, derived from the Greek word ‘macros’ meaning large, examines the economy as a whole, focusing intensely on aggregate phenomena and national performance indicators. This vast field deals with large-scale economic challenges such as the nation’s total output (Gross Domestic Product or GDP), structural unemployment rates across all regions, national inflation rates, public debt, and international trade balances. A macroeconomist assesses, for instance, the comprehensive effect of a new national taxation policy on Ghana’s overall economic trajectory and stability. While distinct in focus, effective national policy requires both micro and macro insights.

The Language of Economics: Positive vs. Normative Statements

Precision in language is vital for economic analysis. Economists must constantly distinguish clearly between statements that describe reality and those that propose how reality should be improved.

A. Positive Economics (“What Is” – Objective Facts)

Positive economics describes, explains, and predicts economic events based strictly on data and logic. It is purely descriptive and relies entirely on objective, testable evidence. Statements in positive economics are factual claims that can, in principle, be verified or refuted through empirical testing.
* Example: “Ghana’s national debt increased by 15% following the 2020 fiscal year.” This statement is objectively verifiable using government records.

B. Normative Economics (“What Ought to Be” – Subjective Judgments)

Normative economics involves value judgments, opinions, and statements about how the economy should or ought to be managed. These statements reflect personal, political, or ethical preferences and cannot be proven strictly true or false using scientific methodology. They often incorporate words like ‘should,’ ‘ought to,’ or ‘must.’
* Example: “To achieve equitable growth, the government should provide generous subsidies for small and medium enterprises (SMEs).” This is a policy recommendation based on a value judgment about fairness.

The Professional Economist and Critical Career Pathways

An Economist is a highly skilled professional who applies sophisticated economic theories and rigorous models to interpret complex data, analyze production and distribution systems, and crucially, advise high-level decision-makers on policy implementation. They are critical thinkers specializing in quantitative analysis and forecasting. Career paths for Economics graduates are extremely diverse and critically important to Ghana’s development. They span both the dominant Private Sector (including roles in Commercial Banking, Investment Analysis, Financial Consultancy, Risk Management, and high-level Entrepreneurship) and the vital Public Sector (such as key roles within the Ministry of Finance, the Bank of Ghana, the Ghana Statistical Service, Academic Research, and specialized positions in International Organizations). The robust analytical foundation provided by economic mastery equips graduates with essential decision-making skills applicable across virtually every sector driving national progress.

Section 3: The Local Laboratory – Economics in Ghana

We witness the principle of scarcity daily. Consider the operation of the GPRTU (Ghana Private Road Transport Union). When making business decisions, a driver must allocate his limited daily profit. He faces a choice: spend resources now on minor repairs and maintenance to ensure vehicle safety (a necessary cost), or save the money for his child’s school fees next term (a consumption choice). Every cedi spent on repairs is a cedi that cannot be used for schooling—this is the opportunity cost inherent in scarcity. Furthermore, the GPRTU itself, when negotiating fare increases, often uses positive data (the rising cost of fuel—a verifiable fact) to support its normative claim (“Therefore, fares should increase to maintain profitability”).

On a large scale, government policy regarding food imports versus investment in local agriculture is a major macroeconomic trade-off, always guided by the question: How do we best allocate the nation’s finite budget to maximize welfare? This is economics applied. Whether an SHS student is choosing between buying ‘koko’ or bread for breakfast due to limited pocket money (a microeconomic choice) or analyzing Ghana’s current debt-to-GDP ratio (a macroeconomic concern), economics provides the indispensable framework for rational decision-making rooted in the fundamental constraint of scarcity.
