Concept of Choice
Because resources are limited, we must make choices. In economics, scarcity means our resources (money, time, raw materials) can never satisfy everyone’s wants or needs. Therefore, every decision we make involves a choice.
Example: Suppose you have £5 and want to buy both Tesco Finest Scottish shortbread (£3) and a tartan scarf (£4). You cannot afford both, so you must decide which one you value more. This decision involves an opportunity cost.
All choices made by individuals, firms, or governments have a cost associated with them, known as the opportunity cost.
What is the opportunity cost?
Opportunity cost is the value of the next best alternative that you sacrifice when making a choice. In simpler terms, it’s what you give up whenever you decide on one option over another.
All societies face this issue. Whether it’s a consumer deciding how to spend money or a government allocating tax revenue, there is always a trade-off. Opportunity cost helps us think about these trade-offs more clearly.
Effect of opportunity cost/scarcity on different groups - individuals, firms and governments
Group | Effect of opportunity cost | Effect of opportunity cost on decision-making examples |
Individuals | Every day, you and I face choices with opportunity costs. | Personal Choices: Deciding whether to spend money on a concert ticket or save it for a new phone.
Time Management: Choosing to spend time studying versus hanging out with friends.
Career Decisions: Choosing between taking a job immediately or going to college. |
Firms | Firms cannot produce everything they want due to limited resources and revenue. They must prioritise how to allocate resources to maximise profits.
| Resource Allocation: Deciding whether to invest in new technology or expand the workforce.
Product Development: Choosing to develop a new product line versus improving an existing one.
Market Entry: Deciding whether to enter a new market or consolidate in the current market. |
Governments | Governments have limited tax revenue so cannot provide all
the services they want to.
Governments have to make choices about how to spend revenue to maximise social welfare. | Budget Allocation: Choosing to fund healthcare over education.
Policy Decisions: Deciding to implement environmental regulations versus economic growth initiatives.
Infrastructure Projects: Choosing to build new highways versus investing in public transportation. |
Importance of Scarcity, Choice, and Opportunity Cost: Scarcity helps us understand decision-making in the face of limited resources. The valuation of scarce goods and services, like gold and diamonds, highlights their importance in economic choices and resource allocation.
