Answer:
moral hazard
Step-by-step explanation:
Banks reduce the risk of moral hazard when they monitor and supervise how their clients are using the loans and credits made to them.
Some types of credits do not require any type of monitoring or control, e.g. a credit card which a client can use basically however he/she wants to. But other types of credit that are taken for purchasing assets, e.g. a mortgage, must be used by the bank's client to specifically carryout the intended activity.
In economics, moral hazard refers to the tendency that an economic party can engage in unusually risky activities because the capital (money) that they are investing is not theirs and the negative effects of a potential loss will be suffered most by other parties.
