Home Import Demand With Home demand of D and supply of S, the no-trade equilibrium is at point A, with the price P^A and import quantity Q₀. Import demand at this price is zero, as shown by the point A′ in panel (b). At a lower world price of P^W, import demand is M₁ = D₁ − S₁, as shown by point B. Joining up all points between A′ and B, we obtain the import demand curve, M.
