討論提要 |
This paper compares the welfare ranking of
optimal tariffs and quotas with and without market uncertainty. The conventional wisdom suggests that
with certainty a tariff is in general superior to a quota due to the tariff
revenues. In this paper, we have
shown that the opposite may hold if the market is with a sufficient amount of
uncertainty. This is because
when the uncertainty is sizable, the domestic government should choose a
quota instead of a tariff as a means of restricting imports so as to prevent
the foreign firm from responding to the state of nature. |
||
結論 |
Under a quota regime, when the market uncertainty is sufficiently
large the home country should let the domestic firm maintain monopoly power
in order to have a stable supply; but when the market uncertainty is small,
the domestic government should open up the market to increase the market
competition, even if the foreign firms enjoy a significant cost advantage
over the domestic firms. |

延伸研究 |
Will
the degree of convexity of demand affect the welfare ranking tariff and
quota? |
