This topic analyzes how government intervention (taxes or subsidies) affects market equilibrium, consumer surplus (CS), producer surplus (PS), and total efficiency (DWL).
Tax Wedge: A tax ($\tau$) drives a wedge between the price buyers pay ($P_d$) and the price sellers receive ($P_s$).
$P_d = P_s + \tau$
The new equilibrium quantity ($Q_t$) is found where $Q_d(P_d) = Q_s(P_s)$.
Subsidy Wedge: A subsidy ($s$)
