Economics: The Science of Scarcity and Rational Choice | Economics SHS 1 SEM 1 WEEK 1 (WASSCE & NaCCA Aligned)

We begin our journey into Economics, not in a dusty textbook, but right here in our homes, schools, and markets—the very places where choices are made. As the Lead Master Teacher for School Support, I confirm that this SHS 1 SEM 1 WEEK 1 module is 100% aligned with the NaCCA Content Standard: *Demonstrate knowledge and understanding of fundamental concepts and tools used in Economics.*

**Period 1: The Core Problem: Scarcity**
The fundamental economic problem facing every society, from a Ghanaian household to the Ministry of Finance, is **Scarcity**. Scarcity exists because human wants are virtually unlimited, but the resources available to satisfy those wants are finite (limited). When a mother in Accra must choose between buying ‘koko’ for breakfast or using the money for her child’s transport fare, she is facing scarcity. Scarcity forces choice, and choice means sacrificing the next best alternative (opportunity cost, introduced later).

Resources—the inputs used to produce goods and services—are broadly classified as Land, Labour, Capital, and Entrepreneurship. Because these are limited, we must allocate them efficiently. This leads to our definition: **Economics is the social science that studies how individuals, institutions, and societies make optimal choices under conditions of scarcity.**

We differentiate between **Goods** (tangible items, like a sack of yam or a school desk) and **Services** (intangible actions or activities, like teaching, banking, or a tro-tro ride). WASSCE often tests your ability to classify these correctly. Differentiating for ‘Approaching Proficiency’ learners, we focus on simple choices, like choosing between buying bread or kenkey—this makes the abstract concrete.

**Period 2: Defining the Scope: Micro vs. Macro**
Economics is studied at different levels, leading to two main branches:

1. **Microeconomics (The Small Picture):** Focuses on the behaviour of individual decision-making units, such as a single consumer (household), a single firm, or the price of a specific commodity.
* *Ghanaian Analogy:* Studying why the price of tomatoes increased specifically at Makola Market this week.
* *WASSCE Strategy:* Look for words like ‘individual,’ ‘firm,’ ‘market price,’ or ‘demand for product X.’

2. **Macroeconomics (The Big Picture):** Focuses on the aggregate economy as a whole. It deals with large-scale economic phenomena.
* *Ghanaian Analogy:* Analyzing Ghana’s national unemployment rate, the overall rate of inflation, or the effects of the national budget deficit.
* *WASSCE Strategy:* Look for words like ‘National Income,’ ‘GDP,’ ‘Inflation,’ ‘Unemployment Rate,’ or ‘Government Policy.’

**Objective Truths vs. Value Judgments**
Economists communicate using two types of statements, and WASSCE examiners frequently test this distinction:

1. **Positive Economics:** Statements are based on facts, data, and cause-and-effect relationships. They describe *what is* and can be tested or verified.
* *Example:* “Ghana’s government introduced free primary education.” (Testable fact).

2. **Normative Economics:** Statements involve value judgments, opinions, and beliefs about *what ought to be*. They are subjective and cannot be proven true or false.
* *Example:* “The government should provide subsidies for Ghanaian farmers.” (Policy recommendation/opinion).

**Period 3 & 4: The Role of the Economist in Ghana**
An **Economist** is a professional who studies the production, distribution, and consumption of goods and services, applying theoretical models and empirical data to solve real-world problems. The career prospects for Economics graduates in Ghana are vast, spanning both the Public and Private Sectors.

* **Public Sector:** Economists serve as Policy Analysts at institutions like the Bank of Ghana (BoG), the Ministry of Finance, and the Ghana Statistical Service (GSS). They are crucial in implementing national policies, managing debt, and forecasting economic trends critical for Ghana’s stability.
* **Private Sector:** Roles here include Investment Bankers, Financial Analysts, Market Researchers, and Consultants. For instance, an economist working in private banking uses complex models to determine the optimal interest rate for loans, directly impacting Ghanaian businesses and households.

**WASSCE Examination Strategy:**
When attempting definition questions in WASSCE Paper 2, ensure your definition of Economics incorporates the three crucial elements: **Scarcity, Choice, and Unlimited Wants**. For classification questions (Micro/Macro), identify the *scope*—is the focus individual/firm (Micro) or national/aggregate (Macro)? Mastering this foundational WEEK 1 content sets the stage for success across the entire SHS curriculum. School Support provides targeted resources and assessment keys tailored to these fundamental NaCCA requirements.
