8U2. Consider again the case of the 2011 Citrus. Almost all cars depreciate over time, and so it is with
the Citrus. Every month that passes, all sellers of Citrus - regardless of type - are willing to accept $100
less than they were the month before. Also, with every passing month, buyers are maximally willing to
pay $400 less for an orange than they were the previous month and $200 less for a lemon. Assume that
the example in the text takes place in month 0. Eighty percent of the Citruses are oranges, and this
proportion never changes.
(a) Fill out three versions of the following table for month 1, month 2, and month 3.
Willingness to accept of sellers Willingness to pay of buyers
Oranges
Lemons
(b) Graph the willingness to accept of the sellers of oranges over the next 12 months. On the same
figure, graph the price that buyers are willing to pay for a Citrus of unknown type (given that the proportion of oranges is 0.8). (Hint: Make the vertical axis range fro 10 000 to 14 000.)
(c) Is there a market for oranges in month 3? Why or why not?
(d) In what month does the market for oranges collapse?
(e) If owners of lemons never experienced depreciation, i.e., they were never willing to accept anything
less than $3000, would this affect the timing of the collapse of the market for oranges? Why or why not?
In what month does the market for oranges collapse in this case?
(f) If buyers experienced no depreciation for a lemon, i.e., they weree always willing to pay up to $6000
for a lemon, would this affect the timing of the collapse of the market for oranges? Why or why not? In
what month does the market for oranges collapse in this case?
(a) Fill out three versions of the following table for month 1, month 2, and month 3.
Month 0
Willingness to accept of sellers Willingness to pay of buyers
Oranges $12,500 $16,000
Lemons $3,000 $6,000
Month 1
Willingness to accept of sellers Willingness to pay of buyers
Oranges $12,400 $15,600
Lemons $2,900 $5,800
Month 2
Willingness to accept of sellers Willingness to pay of buyers
Oranges $12300 $15,200
Lemons $2,800 $5,600
Month 3
Willingness to accept of sellers Willingness to pay of buyers
Oranges $12,200 $14,800
Lemons $2,700 $5,400
(b) Graph the willingness to accept of the sellers of oranges over the next 12 months. On the same
figure, graph the price that buyers are willing to pay for a Citrus of unknown type (given that the proportion of oranges is 0.8). (Hint: Make the vertical axis range fro 10 000 to 14 000.).
Let t denote the month. For t = 0, 1, ..., 12, the willingness to accept of the seller of an orange is
willingness to accept for sellers
For a buyer, the willingness to pay for an orange in month t is
������� b[1, t_] := 16 000 - 400 t
For a buyer, the willingness to pay for an orange in month 0 is
