Hello!!!
We will be looking another type of information failure today Asymmetric Information. We will study how asymmetric information causes market failure, namely through Adverse Selection and Moral Hazard. Do ensure you nail down the various ways and examples in which these occur!

Signaling

ชมวิดีโอด้านล่าง

A signal is an action that reveals information. Let’s look at higher education, for example. A large fraction of the value you receive from your degree comes on the day you earn your diploma. Your expected wages don’t increase with each class you complete along the way; instead, they spike sharply at the end when you receive your diploma. This is often referred to as the “Sheepskin Effect” because diplomas used to be printed on sheepskin.
Nobel Prize winner Michael Spence did research on this subject and found that education is valuable not necessarily because it creates valuable skills, but rather that it signals valuable skills. So how does the signal, represented by a degree, alleviate asymmetric information?
Employers don’t necessarily know how smart or skilled you are. Your degree, however, provides a credible signal of these traits and gives them more information they can use in the hiring process.
What other signals exist? We discuss examples like diamond engagement rings, why criminals tattoo their face, and why a peacock has a colorful tail. Let us know what examples you come up with in the comments.
