➤ Why are supply-side measures important to slow inflation?
Supply-side reforms address cost-push inflation by easing production and distribution bottlenecks. Actions include investing in infrastructure, improving energy supply, reducing red tape, and boosting competition and workforce skills. These steps raise productivity, lower unit costs, and increase output, which helps contain prices without relying only on demand reduction.

➤ Why does average fixed cost fall as production increases?
AFC falls because a fixed total cost is spread over more units. As output rises, the same TFC divided by a larger Q yields a smaller cost per unit. This spreading effect creates the downward slope of the AFC curve and lowers the fixed-cost component of unit cost with greater production.

➤ How can economists test if consumers actually pay the full tax?
Economists compare pre‑ and post‑tax prices, estimate pass‑through rates, and use natural experiments or difference‑in‑differences regressions. They check changes in the price paid by buyers versus price received by sellers, control for supply and demand shifts, and measure quantity responses to infer incidence and relative elasticities.

2. Why doesn’t a seller-side tax shift the demand curve?
A tax on sellers affects costs and the supply schedule, not buyers’ willingness to pay. The demand curve represents consumers’ marginal willingness to pay at each quantity. Since the tax changes sellers’ behavior rather than buyers’ preferences or income, the demand curve stays in place while supply shifts.
