Q

The demand for domestic goods: calculation

A

Z = C + I + G - IM/e (exchange rate) + X

–> subtracting the value of imports from domestic demand and then adding exports.

Q

Domestic demand for goods : calculation

A

C + I + G = C(Y-T) +I( Y,r)+G

–> Consumption depends positively on disposable income
–> investment depends positively on production, Y, and negatively on the real policy rate, r.

Q

Trade deficit

A

buying more from the rest of the world than it is selling to the rest of the world

Q

current account balance

A

all financial transactions between residents of a country and the rest of the world
–> flow of goods, services, income, and transfers,

29
Q

current account surplus

A

If net payments from the rest of the world are positive

30
Q

current account deficit

A

If net payments from the rest of the world are negative

31
Q

financial account

A

flow of financial capital and reflects how a country finances its current account balance

32
Q

uncovered interest parity relation: calculation

A

it ≈ i*t - E^et+1 - Et / Et

it : domestic interest rate
it* : foreign interest rate

33
Q

uncovered interest parity relation: definition

A

domestic interest rate must equal the foreign interest rate minus the expected appreciation (or depreciation) of the domestic currency.

34
Q

Application to Exchange Rate Movements (uncovered interest parity relation)

A

interest rates in different countries tend to move together

35
Q

The UIP condition assumes that.. (abritage and expected return)

A

financial investors care only about the expected rate of return and will invest in the bonds with the highest expected return, ignoring differences in risk or transaction costs

36
Q

What affect demand for good ?

A

the interest rate, taxes, government spending, foreign output, and the real exchange rate

37
Q

The demand for domestic goods (graphically )

A

The line ZZ (figure 18.1)

38
Q

Equilibrium condition

A

determines output as a function of all the variables we take as given, from taxes to the real exchange rate to foreign outpu

39
Q

The Effects of an Increase in Government Spending

A

An increase in government spending leads to an increase in output and a trade deficit.

40
Q

The equilibrium level of output is given by..

A

Y = Z
–> The goods market is in equi- librium when domestic output is equal to the demand for domestic goods.

41
Q

The increase in output is larger than the increase in government spending : so what ?

A

There is a multiplier effect

42
Q

The Effects of an Increase in Foreign Demand

A

An increase in foreign demand leads to an increase in output and a trade surplus.

43
Q

An increase in domestic demand leads to

A

an increase in domestic output but also to a deterioration of the trade balance

44
Q

An increase in foreign demand lead to

A

an increase in domestic output and an improvement in the trade balance.

45
Q

Marshall-Lerner condition

A

real depreciation leads to an increase in net exports

46
Q

The depreciation leads to a shift in…

A

foreign and domestic, toward domestic goods

47
Q

Reducing the Trade Deficit without Changing Output, what does the government do?

A

the government must both achieve a depreciation and decrease government spending

48
Q

current account : equation

A

Y = C + I + G + EX − IM

49
Q

Mundell-Fleming model

A

A model of simultaneous equilibrium in both goods and financial markets for an open economy

50
Q

The IS-LM Model in an Open Economy

A

An increase in the interest rate reduces output both directly and indirectly (through the exchange rate). The IS curve is downward sloping, for both reasons. The LM curve is horizontal at the interest rate set by the central bank

–> Figure 19,2

51
Q

The effect of Monetary policy in open economy : increase the interest rate (flexible interest rate)

A

An increase in the interest rate leads to a decrease in output and an appreciation

LM curve change positon

figure 19.3

52
Q

Fiscal policy: The effects of an increase in governing spending with an unchanged interest rate (flexible interest rate)

A

An increase in government spending leads to an increase in output. If the central bank keeps the interest rate unchanged, the exchange rate also remains unchanged

IS curve shift to the right

53
Q

Flexible Exchange Rates: Equilibrium is determined (Mundell-Fleming model)

A

Equilibrium is determined by the IS curve and the interest parity condition, yielding values for 𝑌 and 𝐸
–> the domestic interest rate is set by the central bank and is a key factor in determining the level of domestic output 𝑌

54
Q

The Effects of an Increase in Government Spending
When the Central Bank Responds by Raising the
Interest Rate

A

An increase in government spending leads to an increase in output. If the central bank responds by raising the inter- est rate, the exchange rate will appreciate

IS shift by the right
LM upwards

–> see figure 19.5

55
Q

both consumption and government spending increase, what happened ?

A

consumption goes up because of the increase in income, and government spending goes up by assumption

56
Q

Fixed Exchange Rates: Equilibrium (Mundell-Fleming model)

A

Equilibrium is determined by the IS curve and the LM curve, yielding values for 𝑌 and domestic interest rate
–>The domestic interest rate must equal the foreign interest rate to maintain the fixed exchange rate, which means the intersection of the IS curve and the LM curve will determine both the domestic output Y and the interest rate 𝑖

57
Q

devaluation

A

decrease in the exchange rate under a regime of fixed exchange rates
–> rather than depreciation

58
Q

crawling peg

A

is a type of exchange rate regime in which a country’s currency is fixed to another currency

59
Q

Monetary policy with fixed exchange rate

A

the domestic interest rate must be equal to the interest rate of the foreign country the country is pegging to
–> refer to the interest parity condition

60
Q

Fiscal policy Fiscal Policy When the Exchange Rate Is Fixed

A

By fixing the exchange rate, a country gives up a powerful tool for correcting trade imbalances or changing the level of economic activity.

By committing to a given exchange rate, a country also gives up control of its interest rate

Although the country retains control of fiscal policy, one policy instrument may not be enough
–> a fiscal expansion can help the economy get out of a recession

61
Q

float

A

allow a move from a fixed to a flexible exchange rate regime.
–> in the medium run

62
Q

floating exchange rate regime

A

is the same as a flexible exchange rate regime

63
Q

Expectations that a devaluation may be coming can trigger an..

A

exchange rate crisis

64
Q

To faced to the expectation that a devaluation may be coming can trigger an exchange rate crisis, the government can ?

A
  • give in and devalue, or
  • fight and maintain the parity, at the cost of very high interest rates and a potential
    recession. Fighting may not work anyway; the recession may force the government to change policy later on—or force the government out of office.
65
Q

Exchange rates often move even in the absence of…

A

movements in interest rates

66
Q

a relation among current and expected future domestic and foreign real interest ratese

A

equation (20,5)

67
Q

The exchange rate today depends on both:

A
  1. the difference between current and expected future domestic interest rates, and current and expected future foreign interest rates

2.the expected future exchange rate

68
Q

The interest parity condition implies that..

A
  • differences between domestic and foreign interest rates can be explained by expected changes in the nominal exchange rate.

-if the domestic interest rate is above the foreign interest rate (it > i∗t ), investors expect that the nominal exchange rate will decrease.

-if the foreign interest rate is above the domestic interest rate (i∗t > it), investors expect the domestic currency to appreciate.
