Let (inverse) demand be Pb = 93 - 6 Qb and (inverse) supply be Pv = 29 + 2 Qv. Consider the shift in demand illustrated (the intercept of Pb moves by 14 ), which of the following is the most likely cause of the shift depicted: (1) A decrease in consumer income if the good is NORMAL; (2) A decrease in consumer income if the good is INFERIOR; (3) A decrease in the price of a substitute to the good; (4) An increase in the price of a complement to the good; (5) All of the above.
