Economics - Term 4 - Week 9

Imagine Thandi, who runs a hair salon in Khayelitsha. On days with load-shedding, she cannot use her hairdryers or card machine. She loses customers and income. This is a direct cost: money lost because she cannot operate. Indirect costs are less obvious. For example, Sipho in Polokwane misses an online job interview due to no electricity, affecting his future earnings. Direct costs are immediate and measurable, like lost sales. Indirect costs are longer-term and harder to see, such as reputational damage or missed opportunities. Many learners confuse these, thinking all costs are direct. Remember: direct costs are what you lose now; indirect costs are what you might lose later because of the disruption. For exam answers, always give a clear example for each type. This helps you earn full marks in NSC Paper 1 application questions.

In Durban, Ahmed’s bakery must close for two hours during load-shedding. He usually bakes 100 loaves per hour, selling each for R10. That’s R2,000 lost per outage. Multiply this by 20 days a month, and the loss is R40,000. Productivity means how much output (goods or services) is produced in a given time. Load-shedding reduces productivity because workers and machines stand idle. Some learners think productivity only drops if a business closes permanently. In reality, even a short outage means less is produced and sold. Always check: how many hours were lost, and what could have been made or earned in that time? For example, if a factory in Mthatha loses 10 hours of production each month, that is a real and measurable reduction in productivity, even if the business stays open overall. This is why economists track lost hours and output, not just closures.

Lerato’s family in Soweto uses candles, gas stoves, and rechargeable lights during load-shedding. They plan meals and homework around the schedule. Some families buy generators or solar panels, but these are expensive. Households adapt by changing routines, but this often means extra costs (like buying takeaways) or reduced quality of life (cold showers, no TV). A common mistake is to assume only businesses suffer. In fact, households also lose time, money, and comfort. When analysing economic impact, always consider both business and household adaptations. For example, learners might have to do homework earlier in the day, or parents might need to spend more on transport if traffic lights are out. These changes add up over time and can affect education, health, and family budgets. In NSC exams, mentioning both business and household responses shows deeper understanding.

Step 1: Identify the business and the outage. Sipho’s internet café in Polokwane loses power for 3 hours, twice a week. Step 2: Find the usual income per hour. He earns R200 per hour. Step 3: Calculate weekly loss: 3 hours × 2 days × R200 = R1,200. Step 4: Calculate monthly loss (4 weeks): R1,200 × 4 = R4,800. Step 5: Double-check the calculation by confirming the frequency and rate. Final answer: Sipho loses R4,800 per month due to load-shedding. Sanity check: The numbers match the frequency and rate given, and the calculation is logical for the scenario.

Step 1: Read the data. A survey shows Durban factories lose 10% of production monthly due to outages. Step 2: Find the normal output. A factory produces goods worth R500,000 per month. Step 3: Calculate the loss: 10% of R500,000 = 0.10 × R500,000 = R50,000. Step 4: State the result. Each month, the factory loses R50,000 in output. Step 5: Sanity check: 10% is a reasonable share of the total, and the calculation fits the data. If the factory had no outages, it would earn the full R500,000. This shows how even a small percentage loss can have a big impact on profits and jobs.

Question: Ahmed’s bakery in Durban loses R2,000 per day in sales during load-shedding. Customers start going to a competitor. Which is the direct cost, and which is indirect? Let’s think: Direct cost is the R2,000 lost daily. Indirect cost is losing customers to competitors, which affects future sales. Model answer: Direct cost = daily lost sales; Indirect cost = future loss of loyal customers. Now you try: Lerato’s family spends R300 extra per month on takeaways during outages, and her brother’s exam marks drop. Which is direct, and which is indirect? Answer: Direct = R300 extra spent; Indirect = lower exam marks. Remember to always give a reason for your classification.

Question: Thandi’s family buys a generator for R5,000 and spends R400 per month on fuel. How much do they spend in six months? Let’s work it out: R400 × 6 = R2,400 on fuel. Add the generator: R2,400 + R5,000 = R7,400 total. Model answer: Thandi’s family spends R7,400 in six months. Your turn: If Sipho’s family buys rechargeable lights for R600 and spends R50 per month on batteries for 8 months, what’s their total cost? Answer: R600 + (R50 × 8) = R1,000. Always show your working for full marks in calculation questions.

1. Define direct cost with an example from your community, such as a shop losing sales during an outage. 2. List two ways households adapt to load-shedding, like using candles or planning meals earlier. 3. State one government response to power outages, for example, building new power stations or supporting solar projects.

1. Calculate the monthly loss for a shop that loses R500 per day for 10 days each month. 2. Explain the difference between direct and indirect costs using your own words and examples. 3. Interpret this data: A taxi business loses 5 hours per week due to load-shedding. What is the impact on their income and service?

1. Analyse how load-shedding affects both businesses and households in your area, using local examples. 2. Justify whether investing in solar panels is a good response for a small business, considering costs and benefits. 3. Predict the long-term effects on employment if load-shedding continues for two years, and explain your reasoning.

• Loss of daily sales during outages
• Customers switching to other shops over time
• Increased stress for the owner
• Reduced community trust in the business

Answer: Loss of daily sales during outages

Direct costs are immediate and measurable, like lost sales. The other options are indirect or non-economic effects.

• Buying candles
• Paying more for takeaways
• Missed homework leading to lower marks
• Purchasing a generator

Answer: Missed homework leading to lower marks

Indirect costs are future or less visible losses, like lower marks from missed homework. Many learners confuse extra spending with indirect costs, but indirect costs are about future impacts, not immediate expenses.

• R2,400
• R3,600
• R3,000
• R4,200

Answer: R3,600

R300 × 12 = R3,600. Many learners mistakenly multiply by 30 or 31, not the number of affected days.

• Using rechargeable lights
• Cooking with gas instead of electricity
• Skipping meals
• Buying a generator and fuel

Answer: Buying a generator and fuel

Generators and fuel have high upfront and ongoing costs, unlike the other options. Many learners underestimate the total expense of running a generator compared to smaller adaptations like rechargeable lights.

• It produces 15% more goods
• It produces 85% of normal output
• It closes permanently
• It loses 15% of its workers

Answer: It produces 85% of normal output

Losing 15% means only 85% of expected goods are produced. Some confuse output loss with worker loss.
