The effects of import tariff in small nation Ad valorem import tariff in 100%

amount doubled the domestic price of commodity X in small nation (Pw to Pw+t)

Did the world price change? Did consumers’ & producers’ surplus

change? Who collects the revenue from an

import tariff and in what amount?

11

DWL

Dead-weight loss (protection costs) arise from the imposition of import tariff in small nation

DWL=CS+PS+GR==DWL=-(a+b+c+d)+a+c==DWL=-(b+d)

12

Costs and benefits for a small nation? Import tariff in small nation redistributes

income from… …domestic consumers (who pay higher

price for the commodity) to domestic producers of the commodity (who receive the higher price)

This leads to inefficiencies (protection costs) of the tariff

Small nation always loses from the imposition of the import tariff

13

Quotas

DEF: A quota is a direct quantitative restriction on the amount of a commodity allowed to be imported or exported in a nation

14

Types of quotas

Import quotas (most common) Export quotas (in form of VERs) Reasons to use quotas?

Import quota has the same effects as an equivalent import tariff for the nation

Try to determine equivalent ad valorem import tariff?

Who gains quota revenues?

What if we used offer curves?

Using the offer curve for small Nation A, show graphical demonstration of an import quota in the same nation
