Why do markets fail?

Market failure refers to the situation where the market is unable to allocate resources effectively and fairly. In some cases, market mechanisms may lead to uneven distribution of resources, which requires government or other institutions to intervene to correct this failure. Here are some reasons that may lead to market failure:
