A government increases an indirect tax on each pack of fireworks from £1 to £2. Demand for the packs is highly price inelastic.
Why might the increase in the tax rate raise total tax revenue?
The tax per pack has doubled, so revenue doubles even if sales halve
The higher tax lowers suppliers' costs, so they supply more packs
Sales fall only slightly, so the extra tax per pack outweighs the lost sales
Firms earn more profit on each pack, so they pay more tax on their profits
