Final exam study Flashcards
CA formula
y-(C+G+i)
Exp-imp
savings- investments
Financial account formula
sales of domestic assets to foreigners- purchase of foreign assets by domestics
FA = outflow- inflow
balance of payment formula
CA+FA+KA = 0
Net foreign assets formula (Bt)
Stock of foreign assets held by domestic residents- stock of domestic assets held by foreigners
(1+r)*Bt-1 + NXt
What’s the uncovered interest parity (UIP) condition?
R$ = R (E) + (Ee $/(E) - E$/(E) )/ E $/(E)
Whats the interest rate parity condition (CIP) ?
R$ = R (E) + (F$/(E) - E$/(E) )/ E $/(E)
where F is the forward exchange rate
What’s the purchase power parity?
P $ = E $/(E) * p (E)
What’s fisher equation?
R $t = R (E)t + expected inflation of t+1 of the us dollar + expected inflation of t+1 of the euro
Whats the aggregate demand ?
It’s the DD curve in the E/Y graph, DD= Y, for given level of E, gives the output that leads to equilibrium
What affects the AA curve?
The exchange rate shifts the AA curve right if it depreciates, left if it appreciates.
What’s a monetary policy?
The central bank changes the supply of monetary assets
What’s a fiscal policy?
A change in the amount of government purchases or taxes
what’s the exchange rate passthrough?
% by which imports prices change when the value of the domestic currency changes
what’s the fiscal multiplier?
% increase in G leads to how much % increase in y
what’s a sterilization?
offset of the change in domestic money supply following the purchase/selling of foreign bonds, to keep money supply unchanged = no impact on prices
Why domestic and foreign assets may not be perfect substitutes?
- exchange rate risk; if there is a higher risk of the currency to depreciate than the domestic borrower must pay a higher interest rate to compensate foreign lenders.
- Default rick; a country’s borrower may default on their loan repayment, lenders will require higher interest rate to compensate.
If the domestic assets are riskier than foreign assets, what will the equilibrium need?
A premium to compensate
When the central bank sells domestic bonds, what does it do to the premium?
It increase it, the central bank affects the risk premium when sterilizing a foreign market operation. When central bank purchase domestic bonds it decreases the premium. The more the private sector holds bonds, the riskier it it so the higher the premium is.
Name and explain the 5 unconventional monetary policy
1- Quantitative easing: CB directly buys long-term government bonds and other securities. Want to reduce long-term interest rates to encourage borrowing and spending.
2- Forward guidance: CB annonces futures paths to affect long-term bond yields.
3- Negative Interest rate: Let the short-run interest rate go slightly negative, banks will owe the Cb so they will shift to other assets driving down the interest rate.
4- Yield Curve Control: CB sets a target to medium-term gov.bonds
5- Reduce/Eliminate Reserve Requirements: CB eliminated reserve requirements for commercial banks to keep their money in the Bank of canada.
What’s the function of the risk premium?
p(B-A)
B: total stock of government bonds issued by the gov.
A: Amount of government bonds held by the CB
So p depends on the amount of gov. bonds held by the market.
When the risk premium increase whaat does it do the Exchange rate?
The domestic currency depreciates to keep the equality in the UIP.
What are the factors that can move the AA curve?
Any factors that shift the money market and foreign exchange market equilibrium shifts the AA curve:
A change in Money supply (increase in Ms shift AA right)
A change in the Expected Echange rate (If the currency is expected to depreciates it shift the AA curve right)
A change in prices (Increase in prices, decreases the supply of real monetary assets, the AA curve will shift left)
What are devaluation and revaluation?
changes in the fixed exchange rate caused by the central bank
For Devaluation to occur what does the central bank needs to do?
Buy foreign assets
What is self-fulfilling expectations?
Investors expect an increase in the domestic currency to devalue, investors will retire their money from domestic investment and demand for domestic investment will decrease.
The central bank will have to sell foreign assets to reduce money supply, to increase the interest rate to keep the E fix.
What are the option the central bank has when facing a self-fulfilling event?
Either risk running out of foreign reserves (can break the peg) or devaluate the exchange rate
What are the risk of devaluating the exchange rate?
Debt denominated in foreign currency will be costlier to repay = trigger default on private and public debt.
Inspectors may expect new future devaluation (loose credibility)
What is the internal balance goal?
price stability and full employment
What is the external balance goal?
Avoid too large CA deficits or surpluses
What’s a capital fligth?
Assets or money flow out of a country rapidly because of a macroeconomic event.
What is the open-economy Trilemma?
You can’t have those 3 simultaneously:
- Exchange rate stability (peg)
- Monetary policy oriented toward domestic goals (Monetary policy independence)
- Free international capital movements
What’s a contingent commitment?
If things get bad enough the central bank/government will intervene
What are the benefits of exchange rate flexibility?
- Monetary policy autonomy
-Automatic stabilization
-Less volatility
-May prevent speculation
-Symmetry (macroeconomic dynamics in the center country may have destabilizing effects in the periphery (pegging country) since this country is using monetary policy for its domestic goals which are different from the pegging country’s goals. )
What is intertemporal trade?
Gains from trading goods and services for assets (savers want to buy assets earning a rate of return and borrowers need resources to consume or invest beyond their current income)
What are the 3 types of offshore banking?
- An agency office located abroad (no deposits, makes loans and transfers; not subject to depository regulations at all )
- A subsidiary bank located abroad: follows the regulation of the foreign country
3.A foreign branch: an office of the home bank located in another country (can take advantage of cross-border regulation differences, carry out the same business as local banks)
What’s an offshore currency deposit?
A bank deposit denominated in a currency other than the domestic currency (ex. USD deposit in a london bank)
