<p>Hidden information concerns <strong>characteristics that are unobservable</strong> by one side of the market. For example, a consumer's willingness to pay, a worker's productivity, the quality of a used car all fall under this category. The characteristics in question are typically assumed to be fixed or very costly to modify. </p>

<p>Moral hazard concerns <strong>actions that are unobservable</strong> by one side of the market. For example, the effort that a CEO puts into managing a company and the care that an insured driver takes to maintain the condition of his car both fall under this category. By their very nature, the (unobservable) actions can be easily changed to suit the incentive structure of the problem. </p>

In fact I have onequestion. For hidden information, in the class, it is said that when does the agent learn his type? Two cases: post contractual And pre contractual. What I understand is that at first the agent does not know his own type. That is type is private info. according to contract signing time, the agent learn his type. If post contractual, agent learn his type after signing. if pre contractual, the agent learn his type before signing contract for example by interview or sitting a test etc. Right?

@studying1234: I'm sorry but your comments are a little confusing for me. Whether the agent learns his type before or after signing the contract does not change the key features of hidden information: types are privately observable and cannot be changed, while actions are observable.

Hidden information concerns **characteristics that are unobservable** by one side of the market. For example, a consumer's willingness to pay, a worker's productivity, the quality of a used car all fall under this category. The characteristics in question are typically assumed to be fixed or very costly to modify.

Moral hazard concerns **actions that are unobservable** by one side of the market. For example, the effort that a CEO puts into managing a company and the care that an insured driver takes to maintain the condition of his car both fall under this category. By their very nature, the (unobservable) actions can be easily changed to suit the incentive structure of the problem.
