Defining opportunity cost
Spec point — "Defining opportunity cost examples of opportunity cost in different contexts"
Defining opportunity cost
- Opportunity cost is the loss of the next best alternative when making a decision
- Due to the problem of scarcity, choices have to be made about how to best allocate limited resources amongst competing wants and needs
Examples of opportunity costs
Consumers
-
Choosing between spending on a new phone or saving for a holiday
-
Going to university or entering employment straight after school
- The forgone income = opportunity cost
Workers
-
Choosing a job with higher pay versus a role with better work-life balance
- The opportunity cost = non-monetary benefits like time or health
Producers/firms
- Using land to grow wheat versus renting it out for wind farming
- Producing product A over product B due to limited factory capacity
Governments
- Spending on education rather than healthcare
- Building roads versus subsidising renewable energy
The influence of opportunity cost on decision-making
Spec point —
1.3.2· "The influence of opportunity cost on decision-making: decisions made by consumers, workers, producers/firms and governments when allocating their resources"
The influence of opportunity cost on decision-making
- Each economic agent weighs what they gain against what they must give up
- When opportunity cost is properly considered, the decision often changes, leading to a more efficient or personally valuable outcome
Consumer
- Ashika wants to visit her best friend in Iceland
- She finds flights from London to Reykjavík: £120 on Friday night, £50 on Thursday night
- She is about to book the Thursday flight, but realises the opportunity cost of saving £70 is missing a full day of work, which would lose her £130 in income
| Analysis |
|---|
| - Ashika books the more expensive flight - She decides the benefit of keeping her work income outweighs the savings on the cheaper ticket - The opportunity cost of the Thursday flight (her lost income) is higher than the cost of the Friday ticket |
Worker
- Ric is choosing between two jobs
- Job A pays £400 more per month but requires daily commuting. Job B pays less but allows him to work from home
- Commuting would cost Ric £40 per week in expenses and around £180 per week in lost time, which he personally values highly
| Analysis |
|---|
| - Ric chooses Job B. He decides that the time and flexibility he gains from working at home is worth more than the higher salary offered by Job A - The opportunity cost of Job A – lost free time and travel hassle – is not worth the extra pay |
Firm
- A firm that sells organic avocados is offered a contract by a large supermarket to buy all of its stock monthly at a low price
- The supermarket is prestigious, but the price offered is lower than what existing customers pay
| Analysis |
|---|
| - The firm declines the deal - It decides the loss in revenue from loyal customers is greater than the benefit of supplying a well-known retailer - The opportunity cost of prestige is outweighed by the income they would have to forgo |
Government
- The Australian Government agrees to supply France with submarines for $70 billion
- Later, the USA offers a similar deal and pressures Australia to cancel the French contract
- The government considers the opportunity cost of damaging trade and diplomatic relations with the USA
| Analysis |
|---|
| - The government cancels the French deal - It determines that maintaining strong ties with the USA brings more long-term benefits - The opportunity cost of denying the US – including access to military deals and trade – is higher than the cost of breaking the French contract |
