SCARCITY: The Fundamental Engine of Ghanaian Choice

Academic Core: The Reality of Unlimited Wants

Every person in Ghana, whether a high-level government official or a street vendor in Kumasi, faces the same fundamental challenge: scarcity. This concept is the cornerstone of all economic study. Scarcity is not about being poor; it is the universal condition that human wants are boundless and infinite, while the resources available to satisfy those wants—land, labour, capital, and entrepreneurship—are fundamentally limited.

When resources are scarce, choices must be made. Economics is formally defined as the social science that studies how individuals, firms, governments, and societies manage the allocation of these scarce resources to satisfy their unlimited wants. This act of choosing necessarily results in a trade-off, where gaining one item means giving up the opportunity to gain another. For instance, if a farmer uses land to cultivate maize, they cannot simultaneously use that same land to build a house.

Goods, Services, and Economic Agents

In the economic landscape, we deal with two primary outputs: Goods, which are tangible items like a bag of rice or a mobile phone, and Services, which are intangible activities performed for others, such as teaching, banking, or transportation by a ‘trotro’ driver. The decisions about these goods and services are made by three main economic agents: Households (consumers), Firms (producers), and the Government (regulators and providers).

The Two Lenses: Micro vs. Macro

To study this complex system, economists use two primary approaches:

• Microeconomics: This lens focuses on the behavior of individual economic units. Think small scale. Microeconomics examines how price is determined for specific commodities like cement or petroleum, how a single bank decides its interest rates, or why a particular household chooses between buying ‘koko’ or bread for breakfast. It deals with individual markets and specific firm decisions.
• Macroeconomics: This lens views the economy as a whole, focusing on aggregate variables. Think large scale, national issues. Macroeconomics studies national income (GDP), overall employment levels in Ghana, the inflation rate of the cedi, or the effect of national budget deficits. It seeks to understand the big picture of economic performance and growth.

Facts vs. Opinions: Positive and Normative Statements

A crucial skill for any budding economist is distinguishing between what is and what ought to be. This separation ensures objectivity in analysis:

• Positive Economics: Deals with statements of fact and cause-and-effect relationships that can be tested and verified empirically. It describes “what is.”

  Example: “The recent increase in fuel prices has caused transport fares to rise by 15%.” This statement can be proven true or false using data.

• Normative Economics: Deals with value judgments, opinions, and what is considered desirable. It describes “what ought to be.” These statements cannot be tested empirically because they are based on personal values.

  Example: “The government should subsidise fertiliser for all smallholder farmers to boost food security.” This is a policy recommendation based on a value judgment about fairness and national priority.

An effective economist uses Positive analysis to understand the effects of a policy before making Normative recommendations on which path Ghana should take. Understanding these foundational distinctions prepares learners not just for exams, but for critical engagement with national economic discourse. Economists in Ghana play vital roles in data analysis, banking, policy formulation within ministries, and corporate strategic planning, ensuring scarce resources are utilised efficiently.

The Local Laboratory: Economics in Ghanaian Life

Food: The Choice of Kenkey

Consider the production of kenkey. A kenkey producer (Firm) has limited time (Labour) and limited maize (Land/Capital). They must decide how much kenkey to produce (Quantity) and what price to charge (Price). This decision falls squarely under Microeconomics. Furthermore, if they decide to use their limited income to buy better grinding machinery instead of hiring more assistants, they are responding directly to Scarcity and making an economic choice.

Landmark: Tema Harbour Development

The decision by the government to invest billions in expanding the Tema Port illustrates a massive national trade-off rooted in scarcity. The government is choosing to allocate scarce national savings and borrowed capital (Resources) to improve trade infrastructure. The decision to expand the port—affecting exports, imports, and national revenue—is a matter of Macroeconomics. This allocation of funds means less money is available for other competing needs, such as building more schools or hospitals.

Policy: Minimum Wage Debates

The discussion surrounding the national minimum wage often mixes Positive and Normative statements. A Positive statement would be: “Raising the minimum wage by 10% will likely lead to a 2% increase in job losses in the informal sector.” A Normative argument used by labour unions is: “The minimum wage ought to be increased significantly to ensure all Ghanaian workers can live above the poverty line.” It is the economist’s job to analyze the data (Positive) before advising on the final decision (Normative).
