Textbook Question
Chapter 16, Problem 20CTQ
A website offers a place for people to buy and sell emeralds, but information about emeralds can be quite imperfect. The website then enacts a rule that all sellers in the market must pay for two independent examinations of their emerald, which are available to the customer for inspection.
- How would you expect this improved information to affect demand for emeralds on this website?
- How would you expect this improved information to affect the quantity of high-quality emeralds sold on the website?
