High Quality Content by WIKIPEDIA articles! In economic theory, a moral hazard is a situation where a party will have a tendency to take risks because the costs that could incur will not be felt by the party taking the risk. In other words, it is a tendency to be more willing to take a risk, knowing that the potential costs or burdens of taking such risk will be borne, in whole or in part, by others. A moral hazard may occur where the actions of one party may change to the detriment of another after a financial transaction has taken place.
