Economics: The Science of Choice in a World of Scarcity | Economics SHS 1 SEM 1 WEEK 1 (WASSCE & NaCCA Aligned)
The Foundation of Economics: Scarcity and Choice
Welcome, future economists! Our journey begins by asking a fundamental question NaCCA requires us to address: Why can’t we have everything we want? The answer, central to all economic thinking, is scarcity. NaCCA Alignment Standard 1 requires us to connect economics directly to your home and community experiences. Think about your family pot at dinner—the ‘Family Pot’ activity we discussed. Is there always enough food for everyone to be fully satisfied, or must your parents make choices about who gets what?
Scarcity exists because human wants are virtually unlimited, but the resources available to satisfy those wants are limited. This applies not just to physical items but also to abstract concepts like money, time, and even governmental budget capacity. Because resources are scarce, we must constantly make choices. This core dilemma stimulates learner interest by relating directly to daily life.
In economics, we classify the outputs of this choice-making process into two basic categories. Goods are tangible items you can touch, such as desks, books, houses, and food (like your morning ‘koko’). Services are intangible activities performed for you, such as teaching, cleaning, a haircut, or a doctor’s consultation. Understanding this difference is key to analyzing production and consumption in any economy.
Defining Economics: Allocation of Scarce Resources
How do we formalize this study? Economics is defined as the social science that studies how individuals, institutions, and societies make optimal choices under conditions of scarcity. This choice-making process involves the efficient allocation of limited resources to satisfy unlimited wants. The NaCCA Learning Outcome emphasizes using relevant information gathered from your environment to define the subject accurately.
Resources, often called the factors of production, are the essential inputs: Land (natural resources), Labour (human effort), Capital (machinery/tools), and Entrepreneurship (the risk-taking ability to combine the other three). The people and institutions involved in this process—households, firms, and the government—are known as Economic Agents.
The challenge of scarcity forces every society, including Ghana, to address three fundamental economic questions: What to produce? How to produce it? And for whom to produce it? The answer to these questions dictates the type of economic system a nation employs.
Micro vs. Macro: Two Lenses of Analysis
To study this complex system, economists use two primary branches of analysis, which we discussed in Period 2. It is crucial to distinguish between them, as they address different levels of aggregation. This fulfills the requirement of applying knowledge to identify specific branches from headlines (Proficient task).
Microeconomics focuses on the behaviour of individual economic units. This includes single households, specific firms, and specific markets. If you are studying why the price of tomatoes increased at Makola Market or how a single company decides to hire new staff, you are conducting Microeconomic analysis. The goal is understanding individual resource allocation.
Macroeconomics, conversely, deals with the economy as a whole (aggregate variables). It examines large-scale issues such as national income (GDP), overall inflation, unemployment rates across the country, and overall economic growth. When the Ministry of Finance discusses strategies to manage Ghana’s national debt, they are dealing with Macroeconomic policy. Both lenses are essential for national development planning.
The Difference Between Fact and Opinion in Economics
Our Essential Question asks: What is the difference between a fact and an opinion in economics? The answer lies in distinguishing between Positive Economics and Normative Economics.
Positive Economics focuses on objective statements about "what is." These statements are factual, based on data, and can be tested empirically. They describe the world without judgment. For example: "Ghana’s government introduced free primary education in 2005." This is a statement of fact.
Normative Economics involves value judgments about "what ought to be." These statements are subjective, expressing opinions, goals, or policy recommendations. They are based on societal values and cannot be tested for truth. They often include words like "should," "ought to," or "better." For instance: "The government should provide subsidies for farmers to boost productivity." This is a policy recommendation, which is an opinion.
High-Proficiency learners are challenged to design critical thinking exercises based on this distinction, recognizing that sound economic policy requires solid Positive analysis before making Normative recommendations.
Career Prospects for the Ghanaian Economist
Who is an Economist? An economist is a professional who studies the production, distribution, and consumption of goods and services, applying rigorous data analysis and theoretical models to understand economic phenomena. Their skills are highly valued because they help organizations make optimal choices under scarcity.
Where can an economist work in Ghana? Economics leads to diverse careers across both the Public Sector (government-owned institutions) and the Private Sector (individual or corporate-owned businesses). We fulfilled Learning Indicator 2 by identifying these prospects through group activities.
Private Sector Careers: These offer opportunities in fields like banking (commercial and investment), financial analysis, consultancy firms, insurance, and entrepreneurship. For example, investment bankers use economic models to advise companies on mergers and acquisitions.
Public Sector Careers: Economists are vital in government organizations such as the Ministry of Finance, the Bank of Ghana (BOG), the National Development Planning Commission (NDPC), and the Ghana Statistical Service (GSS). They work as policy makers, budget planners, and international trade advisors. Their role is to design policies—from managing national debt to structuring social interventions—that lead to sustainable national development.
Whether analyzing the impact of cocoa price volatility (Micro) or advising the President on budget deficits (Macro), the economist’s core job remains the same: using data and theory to guide optimal choices in the face of scarcity. By mastering these foundational concepts this week, you are taking the essential first step toward becoming a critical thinker and a valuable contributor to Ghana’s economic future.
