9-4 A graph of price, P, versus quantity, Q, shows a supply curve, Domestic Supply, rising linearly, and a demand curve, Domestic Demand, descending linearly. The curves intersect at P subscript 1. A horizontal line, World Price, extends from P subscript 0. Area A lies below the demand curve and above the World Price line. Area B lies to the upper left of the point of intersection, below the world price line and the demand curve. Area C lies below Area B and above the supply curve. Area D lies below the World Price line and above the equilibrium price. Refer to Figure 9-4. When the country for which the figure is drawn allows international trade in crude oil, a. domestic crude oil producers sell less crude oil. b. the demand for crude oil by domestic crude oil consumers decreases. c. the losses of the domestic losers outweigh the gains of the domestic winners. d. consumer surplus for domestic crude oil consumers decreases
