Summary: The web and data With the across the board utilization of the web, data is free and ample Free-rider issue if store with great data additionally charges a higher value Sellers in a few markets can pick up “exclusive” rights to offer a thing Buyers can judge ahead of time the quality, in light of who the merchant is

Slide 22

Asymmetric data Some business sectors have venders knowing more about their item for deals than purchasers This is known as lopsided data Most regular sample: Used autos Buyer knows less about the auto than the merchant Some autos are great: “plums” Some autos are terrible: “lemons”

Slide 23

Lemons model When purchasers don't have data as to which autos are lemons and which autos are plums, at times just the lemons go available We will experience two cases to demonstrate a situation where just lemons are accessible available

Slide 24

Example 1 Yugo auto An utilized auto merchant has the accompanying data about utilized Yugo limos: Plums are worth $3,000 to the merchant $1,200 to the proprietor Lemons are worth $250 to the merchant $100 to the proprietor 100 Yugo limos claimed secretly Half of the limos are plums, half are lemons

Slide 25

What ought to the utilized auto merchant offer for Yugo limos? Assume the utilized auto merchant offers $1,201 for utilized Yugo limos 1,201 > 1,200  Plum proprietors offer to merchant 1,201 > 100  Lemon proprietors offer to merchant Profit if each of the 100 are purchased Total worth = 50 ï‚' 3,000 + 50 ï‚' 250 = $162,500 Total expense of purchasing Yugos = 100 ï‚' 1,201 = $120,100 Total benefit = $162,500 - $120,100 = $42,400

Slide 26

What ought to the utilized auto merchant offer for Yugo limos? Should the utilized auto merchant offer a sum other than $1,201? Offer a higher cost  expanded expense for no addition in quality Offer a cost beneath $1,200  just the lemon proprietors would offer their autos Profit if $101 was offered  50 ï‚' (250 – 101) = $7,450

Slide 27

What is the best cost to offer? Offer $1,201  benefit is $42,400 Offer $101  benefit is $7,450 Highest benefit happens if $1,201 is offered

Slide 28

Example 2: Everything is the same aside from the last visual cue An utilized auto merchant has the accompanying data about utilized Yugo limos: Plums are worth $3,000 to the merchant $1,200 to the proprietor Lemons are worth $250 to the merchant $100 to the proprietor 100 Yugo limos possessed secretly One-quarter of the limos are plums, 75% are lemons

Slide 29

What ought to the utilized auto merchant offer for Yugo limos? Assume the utilized auto merchant offers $1,201 for utilized Yugo limos 1,201 > 1,200  Plum proprietors offer to merchant 1,201 > 100  Lemon proprietors offer to merchant Profit if every one of the 100 are purchased Total worth = 25 ï‚' 3,000 + 75 ï‚' 250 = $93,750 Total expense of purchasing Yugos = 100 ï‚' 1,201 = $120,100 Total benefit = $93,750 - $120,100 = – $26,350

Slide 30

Notice here that the merchant will never offer $1,201 Why? Benefits are negative Profits can be zero by not endeavoring to purchase Yugo limos

Slide 31

What ought to the utilized auto merchant offer for Yugo limos? Offer a cost beneath $1,200  just the lemon proprietors would offer their autos Profit if $101 was offered  75 ï‚' (250 – 101) = $11,175 Offer $101 to amplify benefit

Slide 32

What else could the auto merchant do? The merchant could procure a technician to attempt to figure out whether the Yugo limos are lemons or plums Will do it if MB of data surpasses MC .
