Question 1
(a) State and explain one reason for the increase in demand for Electric Vehicles. [2]
- Reason: Stricter carbon emission standards implemented by governments.
- Explanation: Governments may impose penalties on high-emission vehicles or provide subsidies for EVs, shifting consumer preferences toward greener alternatives to avoid costs or benefit from incentives. (Alternatively: Increased environmental consciousness among consumers leading to a preference for sustainable transport).
(b) Use a diagram to explain how an increase in the demand for EVs affects the market for lithium. [4]
- Diagram: A supply and demand graph for lithium.
- X-axis: Quantity of Lithium; Y-axis: Price of Lithium.
- An upward shift of the demand curve ( to ).
- A relatively steep (inelastic) supply curve ().
- Explanation:
- EVs require lithium batteries; therefore, lithium is a key input (complementary relationship in production).
- An increase in demand for EVs leads to a derived increase in demand for lithium.
- The demand curve for lithium shifts to the right.
- Due to the inelastic supply of lithium, this results in a significant increase in the equilibrium price of lithium.
(c) Explain why the supply of lithium is likely to be price inelastic in the short run. [3]
- Capital Intensity/Lead Times: Mining requires massive capital investment and infrastructure (building mines, processing plants).
- Time Lag: It takes years to discover, permit, and develop a new lithium mine.
- Conclusion: Therefore, producers cannot quickly increase the quantity supplied in response to a price increase, making the supply curve steep (inelastic).
(d) Explain how firms in the EV market use non-price competition to gain a competitive advantage. [6]
- Definition: Non-price competition involves competing on factors other than price to increase demand/market share.
- Examples from Extract:
- Product Differentiation (Battery Range/Software): Firms like Tesla focus on superior range and over-the-air software updates, making their product more attractive than competitors.
- Infrastructure (Charging Networks): Building a proprietary charging network (e.g., Superchargers) reduces "range anxiety" for consumers, creating a strong incentive to choose that brand.
- Impact: These strategies create brand loyalty and allow firms to maintain higher prices (price inelasticity of demand) without losing customers.
(e) Discuss whether the dominance of a few large firms in the EV market will necessarily lead to a decrease in consumer welfare. [15]
Arguments that it WILL decrease consumer welfare (Market Power):
- Allocative Inefficiency: Oligopolistic markets may lead to tacit collusion or price leadership. Firms may restrict output and charge prices above marginal cost (), leading to a deadweight loss.
- Reduced Choice: If a few firms dominate, barriers to entry (high R&D costs, infrastructure) may prevent new, innovative startups from entering, potentially limiting the variety of vehicles available.
- Rent-seeking: Firms may spend heavily on advertising or lobbying rather than improving the product.
Arguments that it WILL NOT decrease consumer welfare (Dynamic Efficiency):
- Dynamic Efficiency: High profits (supernormal profits) earned by dominant firms like Tesla or BYD provide the necessary funds for massive R&D. This leads to breakthroughs in battery efficiency and autonomous driving, which eventually benefit consumers through better technology.
- Economies of Scale: Large firms can achieve significant economies of scale in battery production (e.g., Gigafactories), which can lower the average cost of production. If these savings are passed to consumers, prices may actually fall.
- Network Effects: A few dominant players can standardize charging infrastructure, making the entire ecosystem more usable and efficient for all consumers.
Evaluation/Conclusion:
- The outcome depends on the intensity of competition between the few dominant firms. If they engage in fierce non-price competition (as mentioned in Extract 3), consumers benefit from rapid innovation and better quality.
- However, if the market tips into a "stable oligopoly" with high barriers to entry, the risk of higher prices and slower innovation increases.
- Overall, in the early stages of a technological transition, dominance by a few "innovators" often increases welfare through rapid scaling and R&D, whereas long-term dominance without competition may harm it.
