Summer 2013 Quiz 1 ( 50/»1‘7‘01483 1. [25 pts] Abigail, Bob and Cecilia are the only workers at the pottery shop ABC, where they make
mugs and bowls. The following table shows the productivity of each worker per hour: Abigail Cecilia a) [4 pts] Which worker has the lowest opportunity cost of making a mug, and how much is it?

prices. What is the slope of this equal-revenue line? (You do not need to derive the slope; simply state what it is.) Sloye 0( eﬁiMQ—Veucnue UM = - % = -2 d) [5 pts] On the same graph, indicate the point of production that the shop will choose. How many
mugs and bowls will be produced in total? Are any workers going to specialize in the production of mugs or bowls? If so, which ones? 32. bowls mui Lt8 W55 WW be produced in W Bob will sfeuahzc in Mala/15 bowls while AWN Md

the supply curve corresponds to the supply of each worker. 2. [25 points] Donald Duck has three nephews Huey, Dewey and Louie. Each of them has $20 of pocket
money, and they can only spend their money on ice cream. Ice cream comes in two flavors,
strawberry and chocolate; strawberry ice cream costs $1 per pint, while chocolate costs $3 per pint. a) [5 pts] Huey is very particular and likes to consume twice as much strawberry ice cream as he
does chocolate ice cream (in other words, he wants to consume 2 pints of strawberry ice cream
for every pint of chocolate). Draw Huey’s budget constraint and two of his indifference curves: 0 |C1 that passes through the point of4 pints of each flavor
o ICZ that passes through the point of 6 pints of strawberry and 3 pints of chocolate ice cream
ls Huey happier with 4 pints of each flavor, or would he prefer 6 pints of strawberry and 3 pints of chocolate? Label all relevant points and intercepts. Hues is Mwer WM 6 yin-la ai- Sh’ﬁm)be’rg 01-“ fl 3 VAR of

preferences can be represented by the ”usual” smooth, bowed-in indifference curves. Prices are
still pc=$3 and p5=$1. Suppose that you know that Louie consumes 10 pints of strawberry ice
cream when he has $20 in pocket money but would only consume 8 pints of strawberry if he
had $40. Depict this situation using the appropriate tools. What is the economic term for a good such as strawberry ice cream in this scenario? [when demrmd {in (I 300d deems welh cm incmrtge Iii
