To understand trade policy, let’s start by describing it: For which goods do governments usually restrict trade?

Effect of free trade in importable goods

Effect of free trade in exportable goods

Given these effects of trade, what do governments choose to do?Free trade…

for imports helps consumers but hurts producers;

for exports helps producers but hurts consumers.

Which constituencies do governments favor?

…So why do governments restrict imports? the most common arguments against free trade are:

foreigners are “dumping” their products and will raise their prices eventually our producers are “infant industries” and will reduce their costs eventually pollution, labor standards or other “market failures” make prices not reflect full

costs/benefits if we have a large share of the world market, restricting trade could improve

our prices all these could be true, but economists find that they do not actually explain what

governments do

the only plausible explanation is that governments favor some groups over others. This is a significant source of inefficiency and low incomes in all economies!

Beginning from the year 1980, Turkey changed its economic development policy from “import substituting industrialization” to “export led growth” strategy. Economy opened up to world trade, export-promoting incentives were initiated (including tax exemptions, rebates and favorable credit terms), direct import controls have been eliminated, and quantity restrictions have been dismantled. State intervention in the economy was reduced to minimum level. As a result of these efforts, Turkey has increased her share from world markets, from 0,15% in 1980 to 0,6% in the year 2003. Between 1980 and 2004 exports of Turkey has increased from 2,9 billion dollars to 63 billion dollars. Structure of exported goods has also changed much from mainly agricultural products and raw materials to higher value added industrial products. Transformation still continues with increasing exports of transportation vehicles and office equipments.

Trade and Welfare

Autarky/closed economy – the nation is self-sufficient, no trade takes place between nations, and markets are in equilibrium.

Arbitrage – purchasing commodities in one market at a low price and rapidly selling them in another market at a higher price.

Partial equilibrium and excess supply – goods will always move from where prices are low (excess supply) to where prices are high (excess demand).

Page 528

The equilibrium price in the U.S. market is PUS.at prices above PUS, themarket would exhibit excess supply conditions.

At price PE, for example,producers would supplyQSUS3 while consumerswould only want QDUS4.

Why Restrict Trade?

To protect a new or infant industry To counter unfair foreign competition To improve the balance of payments To protect national health, the

environment or food safety

Welfare Effects of Tariff

Consumer surplus before the tariff on the previousslide was equal to area a+b+c+d+e+f+g.

After the tariff, consumer surplus would fall to area e+f+g, or a loss of area a+b+c+d.

Producer surplus increases from area h to area a+hafter the tariff.

The tariff revenue received by the government is equal to area c.

Dead-weight loss to society is equal to area b+d.
