There is frequent confusion about the terms asymmetric information, moral hazard, and adverse selection. Asymmetric information is the cause, while moral hazard and adverse selection are the outcome.
For this discussion, your focus will be to think through what these have to do with hiring a police officer.
Instructions
Consider the following statement:

In your discussion post, address the following:

How does this relate to asymmetric information, moral hazard, and adverse selection?
How do Type I and Type II errors (and the human tendency to be risk-averse) relate to your answer?
