Search can happen sequentially (reviewing one product at a time) or simultaneously (learning about all
products at once). Under sequential search, search costs tend to be higher. It takes more time and
effort. Also, it tends to not achieve the highest CS possible.
As a consumer looks at more products sequentially, costs rise. Eventually costs are really high and the

1) Search Goods
a. Products where consumers can easily obrain information and compare it to alternatives
(i.e. gasoline, etc.)
2) Experience goods
a. Consumers cannot easily capture information between products. Usually rely on
information from others
b. Usually learn the values of product after purchase (i.e. cars, houses, restaurants)
3) Credence Goods
a. Consumers have little accessto information to compare quality is still unknown after
purchase (i.e. auto repairs, supplements, etc.)
b. One thing for sure is that information and disclosure is valuable to firms. More
information means higher change of purchase
Unraveling
In theory, all firms want to disclose information about quality. Even the worst
Suppose there are 10 firms producing a product and each frim has different qualities.
If no firms disclose quality, consumers are expected to evenly distribute between the 10 firms
