Economics Flashcards
Growth of output equation =
Given technology, capital and labour and elesticity of output
Growth of output = growth of technology + α(growth of capital) + (1- α)(growth of labor)
BWP/BMD bid offer
BWP/AUD = 7.88557 - 7.88582
BMD/ AUD = 0.759224 - 0.759264
First step align the equation BWP to and BMD bottom. BMD/ AUD = 1/0.759224 - 1/0.759264 - AUD/BMD = 1.317065 - 1.31713
BWP/AUD bid x AUD/BMD bid = BWP/AUD bid
7.88557 x 1.317065 = 10.3858
BWP/AUD offer x AUD/BMD offer = BWP/AUD offer
7.88582 x 1.31713 = 10.3867
Note bid always lower values and offer always higher value.
Annualised Forward premium =
Annualised Forward premium = [Forward rate - spot rate / spot rate] x 360/180
Covered Interest rate parity
Vs
Uncovered Interest rate parity
Covered Interest rate arbitrage is bound by arbitrage so you cannot make money from trading them. Differing interest rates will offset eachother. Two rates can only predict forward rates
Vs
Uncovered Interest rate arbitrage is not bound by arbitrage so interest rate differentials need not effect returns. Unhedged positions could return the same. Spot rates can be predicted with two risk free rates.
International Fisher relationship =
International Fisher relationship = Ratea - Rateb = Inflationa - Inflationb =
Interest rate differential of a country = Inflation differential of a country
What rate does a fully hedged Argentine investor receive?
Argentina rates 3.4%
US rates 2.8%
Fully hedged investors receive domestic currency. He will receive Argentinian rate of 3.4%
3 month USD/AUD rate =
USD 6%
AUD 5%
3 month USD/AUD rate =
1 + (USD x 3/12) / 1+ (AUD x 3/12)
Carry trade =
Skew (relating to carry trades)
Carry trades make money buy buying the higher yielding asset. But this only works if uncovered interest rate parity holds which is not bound by arbitrage.
FX carry trades have fat tails and negative skew.
Current account =
Capital account =
Current account deficit affect on debt =
Current account = Measures exchange of goods and services. Weather you are selling more than you are importing
Capital account = Measures flow of funds for debt and equity. A current account deficit must experience a capital account surplus in the capital account or depreciate its currency.
Current account deficit affect on debt = Increase in debt levels as a percentage of GDP due to weaker currency making foreign debt more expensive.
Portfolio balance channel =
Flow supply channel =
Portfolio balance channel = investor countries with current account surpluses usually have capital account deficits due to investments in countries with current account deficits. Rebalance dates of investor countries can have a significant negative impact on investee currencies.
Flow supply channel = Current account deficits increase supply of that ccy in the market as exporters to that country exchange that currency on sale of goods. This depreciates the currency and can restore the current account deficit to a balance.
Capital mobility ie changing interest rates (monetary) or changing tax rates (fiscal) all effect currency. Developing markets capital flows are sometimes restricted creating low capital mobility.
High capital mobility (restrictive of expansionary fiscal and monetary policy)
Currency Falls
Currency gains
Low capital mobility
Currency falls
Currency gains
High capital mobility (restrictive or expansionary fiscal and monetary policy)
Currency Falls with restrictive fiscal, expansionary monetary
Currency gains with expansionary fiscal, restrictive monetary
Low capital mobility
Currency falls with expansionary fiscal, expansionary monetary
Currency gains with restrictive fiscal, restrictive monetary
Debt sustainability channel =
Govt approach to big inflows of foreign investment =
Debt sustainability channel = Increased ratio of net external assets to GDP will increase long term value of a ccy
Govt approach to big inflows of foreign investment = impose capital controls and sale of currency in FX markets.
Pure monetary Model =
Dornbusch overshooting model =
Portfolio balance approach =
Pure monetary Model = PPP holds out at any point in time and output is held constant. Ie a 4% increase in money supply creates 4% inflation.
Dornbusch overshooting model = Prices are sticky in the short term and do not immediately reflect changes in monetary policy.
Portfolio balance approach = Focusses on fiscal policy only. Expansionary fiscal policy creates a falling currency, bonds are held if interest rates are higher and currency appreciates. Large budget deficits lead to currency depreciation.
Absolute PPP
vs
Relative PPP
Absolute PPP = Exchange rates are driven by national price levels. Inflation rates in two countries are in equilibrium over time. This does not hold with import tariffs in place.
vs
Relative PPP = Exchange rates are driven by actual inflation levels. Compares the price of a basket of goods utilising the law of one price.
Higher interest rate due to high inflation effect on currency?
Higher interest rate due to higher inflation = weaker currency.
