Open economy Flashcards
(45 cards)
What is a closed economy
Does not interact with other economies in the world (extremely rare)
What is an open economy
- does interact with other economies
- interacting includes buying and selling goods, services and assets
What are exports
Goods and services produced domestically and sold abroad
What are imports
Goods and services produced abroad but consumed domestically
What are net exports (NX)
Exports - imports
(can also be referred to as trade balance)
What is a trade surplus
Positive NX
What is a trade deficit
Negative NX
What are the factors which influence a countries NX
- tastes of consumers for domestic and foreign goods
- prices of goods
- income of consumers
- cost of transporting goods
- policies to international trade
How have imports and exports changed historically
- was 5% of GDP in 1950
- now it is 10-15%
Define net capital outflow (NCO)
Purchase of foreign assets by domestic resident minus the purchase of domestic assets by foreigners
What are the forms of capital flow
- FDI
- FPI
What identity links NX and NCO
NX = NCO
What is the national savings identity
- S = Y-C-G
- S=I+NX
- since NX=NCO,
S=I+NCO - in other words, national savings = domestic investment + net capital outflow
How does the national savings identity act in deficit or surplus
- in surplus NX>0
- NCO=S-I > 0 (since NCO=NX)
What happens in an open economy in trade deficit
Y<C+I+G
Saving<investment
NCO/NX<0
What happens in an open economy in balanced trade
Y=C+I+G
Saving=investment
NCO/NX=0
What happens in an open economy in trade surplus
Y>C+I+G
Saving>investment
NCO/NX>0
What is nominal exchange rate
The rate at which a person can trade one currency of a country for currency of another
Define appreciation
- an increase in the value of a currency
- measured by the amount of foreign currency that one unit of domestic currency can buy
- an appreciation means you can buy more foreign currency for one unit of domestic currency
Define depreciation
Opposite of appreciation
What is the real exchange rate
The ratio at which you can trade goods and services in one country for goods and services in another
How do you calculate real exchange rate
(Nominal exchange rate x domestic price)/ (foreign price)
Give an example of calculating real interest rate
- a banana costs £P in the UK
- use the exchange rate to convert into dollars giving $eP
- divide this by the price of US banana
real exchange rate is calculated using a price index (basket of goods) and not bananas
What is purchasing power parity (PPP)
- the first long run theory of exchange rates
- states that any given currency should be able to buy the same quantity of goods in all countries
- essentially the real exchange rate must equal 1
