  • **Taxes:
    *Taxes*: Market failure can occur when there are externalities (negative or positive) associated with production or consumption.

    • It can influence market outcomes and potentially lead to inefficiencies.

  • Asymmetries of Information:

    • Adverse Selection: This arises from hidden characteristics.
    • Moral Hazard: This arises from hidden actions.
