Suppose in autarky the price of wheat is higher in home
than it is in foreign.
With trade wheat will be shipped from foreign to
home until prices in both countries are the same.

TariffsTariffs
A tariff acts like a transportation cost.
Sellers won’t ship goods unless home price
exceeds foreign price by the amount of the tariff.

TariffsTariffs
A tariff drives a wedge between the prices in
home and foreign.
The price in home rises and the price in foreign
falls relative to free trade.

TariffsTariffsBecause the price with a tariff rises in the home country relative to free trade, home producers supply more and home
consumers demand less.
Home thus imports less(falls from QW to QT).

trade, foreign consumers demand more and foreign

Note on the graph that the quantity of home
imports demanded equals the quantity of foreign exports supplied (at QT)
when PT – PT* = t.

TariffsTariffs
The home price may not rise by the full amount of the tariff because it partly causes the foreign export
price to decline.
The size of the home country matters here.

TariffsTariffsWhen the home country is small, it has no effect on the foreign export price (which stays constant at
the world price) because it is an insignificant part of
the good’s world demand.
PT = PW + t

changes in producer and consumer surpluses.

In contrast to a tariff, an export subsidy worsens
the terms of trade by lowering the price of
exports in world markets.

receives no revenue.

voluntary export restraint voluntary export restraint –works like an import quota,
except imposed by exporting rather than importing country
![Page 46: Trade Policy (Tariffs, Subsidies, VERs) 2/22/2012 Unit 2: Trade Policy](https://reader035.vdocuments.site/reader035/viewer/2022062417/5518c731550346881f8b58a7/html5/thumbnails/46.jpg)
These restraints are usually requested by the
importing country(with the implicit or
explicit threat of a tariffif the exporting country
doesn’t comply).
