The document discusses different types of market failure including: 1) Inefficiencies in production and allocation of resources that prevent markets from functioning optimally. External costs and benefits not reflected in market prices can also lead to inefficient outcomes. 2) Externalities where the prices of goods and services do not reflect the true social costs of production or consumption. This can result in overproduction or underconsumption. 3) Certain necessary goods and services may not be provided by the market alone due to low demand, requiring government intervention.
