ch 9: instruments of trade policy - Krugman/Obstfeld/Meltz
nontariff barriers
- import quotas - export restraints
Pure monopoly protected by *tariff, t*
Domestic industry produces the same Q it would if it were perfectly competitive ↑ domestic P ↑ domestic Q ↓ domestic demand
result of *tariff* - Home consumers (implemented by Home country - raises the price of shipping to Home country)
Home price increase: from P∨w to P∨T - is less than t because par of the tariff is reflected in a decline in F's export price and thus not passed onto the consumers at H
consumer surplus
P consumer pays - P consumer would have been willing to pay = area under the demand curve and above the price
VER v. tariff
VER is more costly to importing country than an = tariff revenue of tariff →→ rents earned by foreigners
efficiency loss
caused because tariff distorts incentives to consume & produce = b + d
terms of trade gain
caused because tariff foreign export P = e if TOT gain = 0 → tariff reduced welfare
net cost of tariff
consumer loss - producer gain - gov. rev. (b+d-e)
how to measure costs/benefits of a tariff
consumer/producer surplus
import demand curve, *MD*
excess of what consumers D & producers S within a country
export supply curve, *XS*
excess of what producers S over what consumers D within a country
how much protection does a tariff/other trade policy actually provide
expressed as: percentage of the price that would prevail under free trade "could raise the price received by US sugar producers by 35%." ad valorem: protection=tarif rate specific: ad valorem protection equivalent = tariff/price net of tariff [[(??? p211)]]
multi-fiber agreement
famous (VER) OMA limited textile exports from 22 countries until 2005
specific tariffs
fixed charge for each unit of goods imported effect = raise the cost of shipping to a country
compare *tariff v. quota* that lead to the same level of imports
if gov. is concerned about domestic monopoly power, tariff is better than quota
when will trade arise in a competitive industry?
if prices are different in the absence of trade
who gain/loses from tariff
importing country consumers - lose exporting country consumers - gain importing country producers - gain exporting country producers - lose importing country gov - gain
import quota
limitation on the quantity of imports
export restraint
limitations of the quantity of exports - usually imposed by an exporting country at an importing country's request
net welfare effects of a tariff
losses set against *The TOT Gain* (=e) that results from the ↓P of foreign exports caused by the tariff
orderly market agreement (OMA)
multilateral VER covering > 1 country
how does a *local content requirement* affect the P for consumers?
no gov. revenue or quota rents p of imports-domestic goods is averaged in final goods and passed onto consumer
domestic monopolist faces competition from imports... free trade v. no trade (D: demand by domestic residents Pw: world P MC: price of single firm)
no trade → D = MR curve *profit maximizing output (of a monopolist)*: MR = MC free trade → [[*w/ free trade, the fact that the dom. industry is a monopoly doesn't make a difference. industry is perfectly competitive*]] monopolists price must be Pw *profit maximizing output (of a monopolist)*: MC = Pw imports = Df-Qf
tariffs/import quotas w/ MONOPOLY
p 232 - 235 try problems first. see if I need to do this
read europes common ag policy

export credit subsidy

red-tape barriers
p227
tariff-inclusive domestic price
paid for import
export subsidy
payment to a firm that ships a good abroad - ad valorem / specific shippers export good up to the point where P_dom - P_foreign > subsidy
effective rate of protection of a tariff rate/ad valorem tariff (p211) t = rate
profitable if: c ≤ (P_good) - (P_capital_good) before: (P_good) = (P_good) after: (P_good) = (P_good)×1.t
voluntary export restraint (VER) or voluntary restraint agreement(VRA)
quota on trade imposed from the exporting country's side ex: limit on auto exports to US enforce by japan, 1981
overall point of a tariff
raise max. P domestic industry can charge → Pw + t
local content requirement
requires some specified fraction of a final good to be produced domestically used by developing countries - shift manufacturing base from --assembly-- to --intermediate goods-- + to local producers of parts - to firms that must buy locally ←effective price to firm is ave of price of imported and dom produced inputs (ex. p227)
effects of export subsidy on P
reverse of tariff (read p218 if don't understand)
world equilibrium w/ tariff, t per unit (of wheat)
suppliers will only ship wheat from F to H if the P at home exceeds that of foreign by at least t → ↑P @ Home → ↓P @ Foreign until P home - P for. ≥ t
consumption distortion loss
tariff leads consumers to consume too little of the good
production distortion loss
tariff leads domestic producers to produce too much of this good = b
ad valorem tariffs
taxes levied as a fraction of the value of imported goods effect = raise the cost of shipping to a country
↓ the tariff-imposing country can drive down foreign export prices (A SMALL COUNTRY)...
the smaller the TOT gain
result of *tariff* - Home producers
↑P received by domestic producers of that good
costs/benefits of tariffs for importing country
↑P_dom ↓P_for ↑production_dom ↓consumption_dom
producer surplus
=P×Q-area under supply curve up to Q
gov revenue =
=volume of imports × tariff rate =Q×t
why is the tariff so inefficient?
???? p 216 Dom. economy produces additional units of good that it could purchase more cheaply abroad
result of a *tariff* implemented by a [[small]] country
A tariff on imports to a [[small]] country cannot affect foreign export prices → raises P of the import in that [[small]] country by the full amount of the tariff, [[t]]! home price increase = P∨w + t → --imports fall in home country but production of that imported good rises [[(why??? p 210)]]
result of *tariff* - Foreign
Smaller export supply because lower P* → reduced supply and increased demand volume of trade declines
compare the effect of 4 major kinds of trade policy on consumer welfare
