A

Nominal interest rates adjust to changes in expected inflation to maintain a relatively stable real interest rate

Q

misallocation of resources from relative-price variability is when:

A

firms don’t raise prices at same time, so relative prices vary
this distorts allocation of resources because businesses and consumers struggle to make informed decisions about production and consumption ultimately leading to inefficient use of resources

Q

inflation makes nominal income grow faster than real income, taxes are based on nominal income and some are not adjusted for inflation.

25
net capital outflow (NCO) =
domestic residents' purchases of foreign assets minus foreigners purchases of domestic assets
26
NCO is also called
net foreign investment
27
NCO: foreign direct investment:
domestic residents actively manage the foreign investment such as the McDonalds in Moscow
28
NCO: Foreign portfolio investment
domestic purchases of foreign stocks or bonds that supply "loanable funds" to foreign firms
29
NCO measures the imbalance in a country's trade in assets. when NCO > 0 this is
"capital outflow" where domestic purchases of foreign assets exceed foreign purchases of domestic assets
30
NCO measures the imbalance in a country's trade in assets. when NCO < 0 this is
"capital inflow" where foreign purchases of domestic assets exceed domestic purchases of foreign assets
31
Nominal exchange rate: =
we express all exchange rates as foreign currency per unit of domestic currency Canadian dollar/ US dollar = 1.29/ 1.00 in this example the US dollar is buying more with less money
32
NCO (Net Capital Outflow) =
NX (Net Exports)
33
What is affected when a foreigner purchases a good from the US
US exports and NX increase the foreigner pays with currency or assets the US acquires some foreign assets causing NCO to rise therefore, NX and NCO both rise
34
S (savings) =
I (investment) + NCO or NX
35
Appreciation:
strengthens/ increases the value of a currency as measured by the amount of foreign currency it can buy
36
Depreciation:
weakens/ decreases the value of a currency as measured by amount of foreign currency it can buy
37
Real Exchange Rate (RER) : Real Exchange Rate (RER)=
the rate where goods and services of one country trade for the goods and services of another country (e x P)/ P* E = nominal exchange rate P = domestic price P* = foreign price
38
E (Nominal exchange rate) =
P*/ P
39
P* (Foreign Price) =
P x e
40
What does the Real Exchange Rate (RER) tell us if it’s = 1 < 1 > 1?
RER = 1, prices are equal RER < 1, domestic prices are cheaper RER > 1, foreign prices are cheaper
41
P :
US Price Level or Consumer Price Index
42
law of one price
the notion that a good should sell for the same price in all markets like if coffee sold for $4/ pound in Seattle and $5/ pound in Boston, costlessly transported this opens an opportunity for arbitrage making a quick profit buying coffee in Seattle and selling it in Boston such arbitrage drives up the price in Seattle and drives down price in Boston, until prices are equal
43
Purchasing-Power Parity (PPP):
a theory of exchange rates whereby a unit of any currency should be able to buy the same quantity of goods in all countries this theory doesn't always hold in practice because some goods are not easily tradable, not always perfect substitutes, price differences reflect taste differences or prices can't be arbitraged away
44
what does the purchasing-power parity (PPP) imply about nominal exchange rates and real exchange rates
nominal exchange rates adjust to equalize the price of a basket across countries while real exchange rates will equal 1
45
Arbitrage:
the practice of taking advantage of a difference in prices in two or more markets – striking a combination of matching deals to capitalize on the difference, the profit being the difference between the market prices at which the unit is traded.
46
PPP isn't perfect but it does work well to explain... the greater a country's inflation rate…
long-run trends the faster its currency should depreciate
47
a change in the money supply (MS) doesn't affect __________ but does affect __________
doesn't affect real variables but does affect nominal variables
48
Quantity of Money Theory =
M x V = P x Y
49
increase price means __________ interest rate
increase interest rate
50
Velocity and real GDP or quantity of production are
constant
51
mD is always _________ and mS is always ________
mD is always constant and mS is always variable
52
Purchasing power:
The value of A currency expressed in terms of the goods and services that it can be purchased with
53
The price level falls. This might be because the Federal Reserve a.bought bonds which raised the money supply. b.bought bonds which reduced the money supply. c.sold bonds which raised the money supply. d.sold bonds which reduced the money supply.
d.sold bonds which reduced the money supply.
54
According to the classical dichotomy, which of the following increases when the money supply increases? a.the real interest rate b.real GDP c.the real wage d.None of the above increases.
d.None of the above increases.
55
If the nominal interest rate is 7 percent and expected inflation is 4.5 percent, then what is the expected real interest rate? a.11.5 percent b.7 percent c.4.5 percent d.2.5 percent
d.2.5 percent real interest rate = nominal interest rate - inflation rate 7 - 4.5 = 2.5
56
When inflation rises, people will desire to hold a.less money and will go to the bank less frequently. b.less money and will go to the bank more frequently. c.more money and will go to the bank less frequently. d.more money and will go to the bank more frequently.
b.less money and will go to the bank more frequently.
57
The nominal exchange rate is 30 Thai baht for one U.S. dollar. A sub sandwich combo deal in the U.S. costs $6 dollars in the U.S. and 120 bhat in Thailand. The real exchange rate equation and answer is:
E (Nominal Exchange Rate) x P (US Price) / P* (Foreign Price) 6 x 30 / 120 = 180 / 120 3 / 2
58
Suppose that a country imports $75 million of goods and services and exports $100 million of goods and services. What is the value of net exports? a. $175 million b. $75 million c. $25 million d. -$25 million
c. $25 million
59
Net Exports =
Exports - Imports
60
Definition of trade balance:
the value of a nation’s exports minus the value of its imports, also called net exports.
