External Sector

How is a country linked with other countries in the global world?

1) There are exchange of Goods and Services2) There are exchange of Assets

What is different?We have Turkish Lira (TL), US has US dollars ($) and European Union has Euro(€)

Foreign currency

• Exchange rate is the TL price of a foreign currency in Turkey.

Eg. 1 $= 2.17 TL (TL price of one dollar) or0.46 $ = 1 TL ( dollar price of one TL)

• If TL price of a $ increases, TL depreciates • (TL becomes less valuable compared to $)

Exchange of Goods and Services

• Exports are the goods that we sell (and foreign economies buy). Hence, it is a source of foreign exchange.

Exports= F( Yforeign, exchange rate)

• Imports are the good that we buy (foreign sell to us). Hence we use foreign exchange to purchase imports

Imports= F( Ydomestic, exchange rate)

Net Exports

• Net Exports = value of Exports- value of imports

Net Exports = F( Y domestic , Yforeign, exchange rate)

This is also called the Trade Balance
