Worked Examples
Worked Example
Question: Analyse how a rise in the National Minimum Wage could affect a fast-food restaurant. (6 marks)
Solution: **Point 1**: One effect of a rise in the National Minimum Wage is an increase in the restaurant's labour costs. **(AO1)** **Chain of Reasoning 1 (BLT)**: **Because** the minimum wage is a legal price floor for labour, the restaurant must pay its low-skilled workers more per hour. **Leading to** an increase in the total wage bill, which is a significant variable cost for a service-based business. **Therefore**, the restaurant's total costs of production will rise, potentially reducing its profit margin, which is calculated as total revenue minus total costs. **(AO3)** **Point 2**: Another effect could be a decrease in employment or staff hours. **(AO1)** **Chain of Reasoning 2 (BLT)**: **Because** labour has become more expensive, the restaurant may look to reduce its reliance on it to protect profits. **Leading to** the manager either employing fewer staff or cutting the weekly hours of existing staff. **Therefore**, this could lead to a rise in unemployment for low-skilled workers in the local area. **(AO3)**
Worked Example
Question: Case Study: The UK government increases the tax on petrol from 58p per litre to 65p per litre. Evaluate the likely economic effects of this tax increase on the UK economy. (12 marks)
Solution: **Introduction**: An increase in an indirect tax like petrol duty will have several effects on consumers, firms, and the government. This response will evaluate the negative impacts, such as inflation and reduced disposable income, against the positive impacts, such as increased government revenue and reduced environmental damage, before reaching a justified conclusion. **Paragraph 1 - Negative Effect on Consumers**: **Because** the tax on petrol has increased, firms (like petrol stations and distribution companies) will likely pass this higher cost onto consumers through higher prices. **Leading to** a rise in the cost of transport for households who rely on cars. **Therefore**, this will reduce consumers' real disposable income, meaning they have less to spend on other goods and services, potentially reducing their standard of living. **(AO2/AO3)** **Paragraph 2 - Negative Effect on Firms**: **Because** transport is a key cost for many businesses, particularly in logistics and retail, their costs of production will rise. **Leading to** firms either absorbing the cost and accepting lower profit margins, or passing the cost onto consumers. **Therefore**, this could lead to cost-push inflation across the economy, making UK goods less internationally competitive. **(AO3)** **Paragraph 3 - Positive Effect on Government**: **Because** the tax per litre has increased, the government will receive more tax revenue for every litre of petrol sold. **Leading to** a rise in the government's tax receipts. **Therefore**, this revenue can be used to fund public services like the NHS or education, or to help pay off the national debt. **(AO3)** **Paragraph 4 - Positive Effect on Environment**: **Because** petrol is more expensive, the law of demand suggests that the quantity demanded will fall. **Leading to** people driving less, switching to public transport, or buying more fuel-efficient cars. **Therefore**, this will reduce the negative externalities associated with driving, such as air pollution and traffic congestion. **(AO3)** **Conclusion (Evaluation)**: In conclusion, the economic effects are mixed, but the negative impacts are likely to be more significant in the short run. The tax is regressive, meaning it will hit low-income households hardest as they spend a larger proportion of their income on transport. While the environmental benefits and increased government revenue are important, the immediate impact of cost-push inflation and reduced consumer welfare is more certain. The magnitude of the effects depends on the price elasticity of demand for petrol; if it is highly inelastic, the fall in demand (and pollution) will be small, and the burden of the tax will fall mainly on consumers. **(AO3 Evaluation)**
