This assignment analyzes the fuel market, focusing on the impact of crude oil price increases on fuel prices, the effects of taxation on fuel, and the elasticity of demand for petrol. The student uses supply and demand diagrams to illustrate these concepts, explaining how changes in crude oil prices affect fuel prices and how taxes impact consumer and producer surplus, leading to market inefficiency. The assignment also discusses the inelastic nature of petrol demand, supported by evidence from the provided article, and illustrates the effects of both relatively inelastic and elastic demand curves on quantity changes in response to price fluctuations. The diagrams help to visualize the concepts of supply, demand, and elasticity, making the economic principles easier to understand.
