The open economy Flashcards
Openness in goods market
the ability of consumers to choose between domestic goods and foreign goods
Openness in the financial markets
The ability for investors to choose between domestic assets and foreign assets
Openness in factor markets
The ability for firms to choose where to locate production, and for workers to choose where to work
tariffs
taxes on imported goods
quotas
restrictions on the quantity of goods that can be imported
Proportion of imports and exports in the UK
30% of GDP today compared to 205 in 1960
In an open economy consumers have two options
save or buy
buy domestic or foreign goods
real exchange rate
the price of the domestic goods relative to the foreign goods
it is not directly observable
Nominal exchange rates can be quoted in two ways
price of domestic in terms of foreign
price of foreign in terms of domestic
Nominal exchange rate
the price of the domestic currency in terms of the foreign currency. denoted by E
nominal appreciation
an increase in the price of the domestic currency in terms of foreign currency. An increase in the exchange rate
nominal depreciation
a decrease in the domestic currency in terms of foreign currency. A decrease in the exchange rate
fixed exchange rates
where two or more countries maintain a constant exchange rate between their currencies
revaluations
increases in the exchange rate under a fixed exchange rate scheme
devaluations
decreases in the exchange rate under a fixed exchange rate scheme
GDP deflator
index of prices for all good produced
real exchange rate relation
ε= EP/P*
ε= real exchange rate E= nominal exchange rate P = price of UK goods in pounds P* = Price of european goods in euros
Constructed by multiplying the domestic price level by the nominal exchange rate and then dividing by the foreign price level
real appreciation
an increase in the real exchange rate. an increase in the relative price of domestic goods in terms of foreign goods
real depreciation
a decreases in the real exchange rate. a decrease in the relative price of domestic goods in terms of foreign gades with the UK and how much it competes with the UK in other countries
multilateral exchange rate
comparing the exchange rates across more than one country by weighing how much each country
foreign exchange
buying or selling foreign currency
Another implication of an open financial market
allows a country to run trade surpluses and deficits
Balance of payments
transactions such as trade flows and financial flows with the rest of the world
Current account transaction
Exports
Imports
UK residents receive investment income
net transfers received - aid
current account surplus/deficit
if the current account balance is positive/negative
net capital flows
the increase in foreign holdings of UK assets minus the decrease in UK holdings of foreign assets
Uncovered Interest parity
riskless arbitrage opportunity stating if financial assets both foreign and domestic are to be held they must have the same expected return
(1+it)=(1+it*)(Et/Et+1)
interest parity condition (to be remembered)
it ≈ it* - (Eet+1 - Et)/Et
arbitrage by investors implies that the domestic interest rate must me equal to the foreign interest rate minus the expected appreciation rate of the domestic currency
Demand for domestic goods in an open economy
Z=C+I+G+IM/ε +X
Determinants of imports
domestic income and the real exchange rate
If domestic income goes up leads to higher demand for all good and thus imports goes up. If the real interest rate goes up the value of imports will go down and so increase the amount bought.
Determinants of exports
Foreign income and the real exchange rate
An increase in the foreign income will increase the demand for all goods including foreign goods and thus exports. An increase in the real exchange rate will decrease the amount of exports as it is more expensive for the foreign country to buy the foreign goods.
Net exports
the difference between the number of imports and number of exports Is positive if exports is greater than imports. and vice versa
trade surplus
exports>imports
trade deficit
exports<imports
According to the interest parity condition an increase in the domestic interest rate leads to….
an increase in the exchange rat
