If you shop for food in a low-income country, you may see a stall like those I frequented growing up: a) Who can better price discriminate Westside Market (our neighborhood grocery store at 110) or the vendor in this picture? Discuss briefly. [There is no single answer here] b) [Based on CT] Suppose you go to a market with multiple vendors like the lady above. You ask for the price of bananas, and all quote the same price: $9 a bunch. Based on models we have seen in class, what are two possible explanations for the fact that they all quote the same price?
