As evidence of health risks continues to increase, governments frequently impose excise taxes to discourage consumption while simultaneously generating revenue for public health initiatives. This analysis evaluates four economic diagrams illustrating the market before and after taxation, changes in economic welfare, and the effects of updated demand conditions. Together, these diagrams demonstrate how taxation influences consumer behaviour, producer incentives, government revenue, and overall market efficiency.</p> <h2>Initial Market Equilibrium Before Government Intervention</h2> <p><strong>Figure 1: Market-Clearing Price and Quantity for Vapes</strong></p> <p>The initial market equilibrium is determined by the interaction of supply and demand. The supply function is represented by QS = 0.1P − 2, while the demand function is represented by QD = 40 − 0.05P. Setting supply equal to demand produces the equilibrium price of 280 pence per millilitre and an equilibrium quantity of 28 thousand litres.</p> <p>At this equilibrium, consumer surplus is represented by the area above the market price and below the demand curve, illustrating the additional value consumers receive beyond the amount paid. Producer surplus is represented by the area below the market price and above the supply curve, reflecting the benefit producers obtain from selling above their minimum acceptable price. The competitive equilibrium allocates resources efficiently because supply equals demand. However, because vaping creates public health costs that are not fully reflected in market prices, government intervention becomes justified to reduce socially undesirable consumption.</p> <h2>Effects of Excise Taxation on Market Equilibrium</h2> <p><strong>Figure 2: Impact of Tax on Market-Clearing Equilibrium</strong></p> <p>Following the introduction of a fixed tax of 150 pence per millilitre, producers experience higher production costs, causing the supply curve to shift upward by the amount of the tax. The new supply equation becomes QS = 0.1(P − 150) − 2. The new equilibrium occurs where the adjusted supply curve intersects the original demand curve.</p> <p>The tax increases the price paid by consumers while reducing the price received by producers after taxation. Consequently, the quantity of vapes sold decreases as consumers reduce purchases in response to higher prices. This reduction in market activity supports the government's objective of lowering nicotine consumption. Nevertheless, the policy also transfers part of the tax burden to consumers while simultaneously reducing producer revenue, illustrating the trade-off between improving public health and maintaining market efficiency.</p> <h2>Changes in Consumer Surplus, Producer Surplus, and Government Revenue</h2> <p><strong>Figure 3: Changes in Surpluses and Tax Revenue</strong></p> <p>The introduction of taxation redistributes economic welfare among market participants. Consumer surplus declines because consumers pay higher prices while purchasing fewer products. Producer surplus also decreases because producers receive lower net prices and sell fewer units after taxation.</p> <p>The government receives tax revenue represented by the rectangular area formed between the consumer price and producer price across the quantity sold after taxation. This revenue may be allocated toward healthcare services, smoking cessation programs, and other public health initiatives.</p> <p>Taxation also creates a deadweight loss represented by the triangular area between the supply and demand curves. This loss reflects mutually beneficial transactions that no longer occur because taxation discourages production and consumption. Although taxation generates valuable government revenue and reduces harmful consumption, it also introduces inefficiencies by reducing total market welfare.</p> <h2>Influence of Updated Demand Conditions on Tax Incidence</h2> <p><strong>Figure 4: Updated Demand Curve and Tax Incidence</strong></p> <p>The final diagram considers an updated demand equation, QD = 80 − 0.1P, reflecting increased consumer willingness to purchase vaping products. With stronger demand, both equilibrium price and quantity increase relative to the original market conditions.</p> <p>After taxation, the higher demand results in greater consumer prices, increased quantities sold compared with the previous taxed equilibrium, and larger government tax revenues because taxation applies to a greater volume of sales. At the same time, consumers and producers continue to experience welfare losses compared with a market without taxation.</p> <p>The revised demand conditions also alter tax incidence. Because demand becomes relatively less responsive to price changes, consumers bear a larger proportion of the tax burden. This demonstrates the importance of accurately estimating market demand when designing tax policies, as changes in consumer behaviour significantly influence government revenue, welfare distribution, and policy effectiveness.</p> <h2>Evaluation of Government Tax Policy</h2> <p>Government intervention through taxation seeks to reduce the negative health effects associated with vaping while generating revenue to support public health programs. Although taxation successfully decreases consumption and provides additional fiscal resources, it also imposes higher costs on consumers, reduces producer earnings, and creates deadweight loss within the market. The analysis further demonstrates that changing market conditions, particularly shifts in demand, substantially influence both the effectiveness of taxation and the distribution of its economic burden.</p> <h2>Conclusion</h2> <p>The economic analysis demonstrates that excise taxation is an effective policy instrument for reducing vape consumption and generating government revenue. However, these benefits are accompanied by reductions in consumer surplus, producer surplus, and overall market efficiency. The updated demand scenario illustrates that accurate market information is essential when designing tax policy because consumer responsiveness directly affects tax incidence, revenue generation, and welfare outcomes. Effective public policy should therefore balance public health objectives with economic efficiency by continuously adapting taxation strategies to changing market conditions.</p> <h2>References</h2> <p>Chaloupka, F.J. and Tauras, J.A.
