Question 3
When an external cost exists that is NOT taken into account in the production of a product,
the level of output is too high, and the supply curve should shift to the left to account for the externality. |
||
the price of the product is too high, and production should be expanded to lower the price. |

government intervention is always needed if externalities are present. |

cattle existing in Europe also while buffalo were specific to North America. |
