00:00:00,990 --> 00:00:01,590
Welcome back.

2
00:00:01,590 --> 00:00:07,680
As we examine the effects of exchange rates on international trade and capital flows we first start

3
00:00:07,680 --> 00:00:12,080
with understanding the relationship between the balance of trade and capital flows.

4
00:00:12,180 --> 00:00:17,460
We shall own the elasticities approach and absorption approach to explain the effect of exchange rates

5
00:00:17,580 --> 00:00:19,770
on trade and capital flows.

6
00:00:19,770 --> 00:00:27,350
Let's get rolling you probably know that when you spend more than you earn you eventually need to borrow

7
00:00:27,410 --> 00:00:31,510
or sell assets to finance the excess spending.

8
00:00:31,590 --> 00:00:38,100
That's the same for countries when a country spends on imports more than it earns from exports.

9
00:00:38,100 --> 00:00:43,980
The trade deficit is financed either by borrowing from foreign countries or selling assets to foreigners

10
00:00:45,700 --> 00:00:51,550
from the balance of payments point of view a current account deficit must be exactly matched by an offsetting

11
00:00:51,550 --> 00:00:52,900
capital account surplus.

12
00:00:53,770 --> 00:00:59,110
So what we're trying to say here is we can study the impact of changing exchange rates on the balance

13
00:00:59,110 --> 00:01:07,090
of payments from two different angles the impact on imports and exports and the impact on capital flows

14
00:01:08,960 --> 00:01:15,660
the elasticities approach focuses on the impact of exchange rate changes on imports and exports while

15
00:01:15,660 --> 00:01:22,730
the absorption approach focuses on the impact on capital flows before we proceed to discuss the two

16
00:01:22,730 --> 00:01:23,750
approaches.

17
00:01:23,750 --> 00:01:29,000
You may recall from the balance of payments lesson that there are three accounts the current account

18
00:01:29,420 --> 00:01:32,420
capital account and financial account.

19
00:01:32,420 --> 00:01:36,980
So what happened to the financial account perhaps for simplicity.

20
00:01:36,980 --> 00:01:42,170
The CFA curriculum refers to Capital Account to include financial account as well.

21
00:01:42,170 --> 00:01:50,230
Put this lesson the elasticities approach focuses on how exchange rate changes affect total expenditures

22
00:01:50,530 --> 00:01:52,930
on imports and exports.

23
00:01:52,990 --> 00:01:59,200
To think of it simply if a country wants to reduce its trade deficit it needs to depreciate its currency

24
00:02:00,070 --> 00:02:05,950
depreciation of the domestic currency will make imports more expensive in domestic currency terms and

25
00:02:06,010 --> 00:02:13,370
exports less expensive in foreign currency terms thus depreciation of the domestic currency will increase

26
00:02:13,430 --> 00:02:19,670
exports and decrease imports and would seem to unambiguously reduce the trade deficit.

27
00:02:19,670 --> 00:02:23,130
However this may not always be the case.

28
00:02:23,180 --> 00:02:28,290
We need to be clear that it is not the change in quantity of imports and exports that matters.

29
00:02:28,490 --> 00:02:33,080
But the change in total expenditures on imports and exports.

30
00:02:33,260 --> 00:02:39,410
This means that we need to study the price elasticity of demand for export goods and import goods to

31
00:02:39,410 --> 00:02:47,360
determine if the desired change can be achieved consider if both demand curves are inelastic a depreciation

32
00:02:47,390 --> 00:02:54,170
in the domestic currency decreases the foreign price of exports but the quantity demanded may only increase

33
00:02:54,230 --> 00:02:55,850
a little.

34
00:02:55,860 --> 00:03:03,700
This means that the total value of exports decrease instead of the intention to increase it likewise.

35
00:03:03,770 --> 00:03:10,520
A depreciation in the domestic currency increases the domestic price of imports but the quantity demanded

36
00:03:10,820 --> 00:03:13,490
may only decrease a little.

37
00:03:13,490 --> 00:03:20,310
This means that the value of imports increase instead of the intention to decrease it if both of these

38
00:03:20,310 --> 00:03:26,730
effects play out the trade deficit actually widens instead of narrowing the central bank policy maker

39
00:03:26,820 --> 00:03:34,430
may get fired for this to help our poor friend Let's teach him the conditions for the change in exchange

40
00:03:34,430 --> 00:03:38,710
rate to have the desirable effects on the trade balance.

41
00:03:38,720 --> 00:03:45,140
This is the generalized Marshall learner condition which is based on the proportion of total trade that

42
00:03:45,140 --> 00:03:51,930
is exports and imports and the price elasticity of demand for exports and imports.

43
00:03:51,980 --> 00:03:59,330
If this condition is satisfied a depreciation of the domestic currency will decrease a trade deficit.

44
00:03:59,410 --> 00:04:06,850
For example if the proportion of exports is 40 percent and 60 percent for imports and the price elasticities

45
00:04:06,850 --> 00:04:12,790
are one point five and one point eight respectively then this amount is greater than zero and the trade

46
00:04:12,790 --> 00:04:16,200
deficit will narrow in this case.

47
00:04:16,270 --> 00:04:23,640
Imports decrease and exports increase narrowing the trade deficit.

48
00:04:23,690 --> 00:04:28,890
In the case where the proportions of import expenditures and export revenues are equal.

49
00:04:29,060 --> 00:04:31,890
This condition reduces to this.

50
00:04:32,120 --> 00:04:40,620
This is most often cited as the classic Marshall loner condition so in general the higher the elasticity

51
00:04:40,620 --> 00:04:46,380
of demand for both export goods and import goods the stronger is the effect of exchange rate changes

52
00:04:46,650 --> 00:04:48,980
on the trade deficit.

53
00:04:49,000 --> 00:04:56,110
For this reason the compositions of export goods and import goods should be studied elasticity of demand

54
00:04:56,170 --> 00:05:01,690
is generally greater for goods with close substitutes goods that represent a high proportion of overall

55
00:05:01,690 --> 00:05:10,030
expenditures on some luxury goods conversely goods that have lower elasticity of demand are goods that

56
00:05:10,030 --> 00:05:17,770
are few or no good substitutes goods that represent a small proportion of overall expenditures and necessities

57
00:05:18,890 --> 00:05:22,370
if the economy primarily imports and exports such goods.

58
00:05:22,400 --> 00:05:29,150
The effect of a currency depreciation may have limited impact or even adverse impact on the trade deficit

59
00:05:30,370 --> 00:05:33,830
ideally if the Marshall learner condition is satisfied.

60
00:05:33,850 --> 00:05:39,910
We wish to see an immediate effect where the trade deficit narrows once the domestic currency is depreciated

61
00:05:41,790 --> 00:05:45,190
however there may be a delay in the effect.

62
00:05:45,210 --> 00:05:50,640
This is because the quantity of imports and exports have not adjusted due to order contracts that were

63
00:05:50,640 --> 00:05:52,310
placed earlier.

64
00:05:52,320 --> 00:05:55,590
However the domestic currency is now weaker.

65
00:05:55,590 --> 00:06:01,380
So while quantities shipped may not have changed import expenditures goes up as the weaker domestic

66
00:06:01,380 --> 00:06:07,860
currency means more units are required to pay for foreign goods so in the short run during this delay

67
00:06:08,130 --> 00:06:13,420
the trade deficit may widen instead of narrowing eventually.

68
00:06:13,450 --> 00:06:19,300
When changes in order quantities take effect the Marshall learner conditions take effect and the currency

69
00:06:19,300 --> 00:06:28,860
depreciation begins to narrow the trade deficit this effect is called the J curve effect one shortcoming

70
00:06:28,890 --> 00:06:34,830
of the elasticities approach is that it only considers the microeconomic relationship between exchange

71
00:06:34,830 --> 00:06:37,100
rates and trade balances.

72
00:06:37,230 --> 00:06:43,380
It ignores capital flows which must also change as a result of a currency depreciation but improves

73
00:06:43,380 --> 00:06:50,230
the balance of trade the absorption approach is a macroeconomic technique that focuses on the effect

74
00:06:50,230 --> 00:06:55,940
of exchange rates on capital flows in the lesson on balance of payments.

75
00:06:55,950 --> 00:07:02,520
We learnt this fundamental relationship between the balance of trade national savings and private investments

76
00:07:03,570 --> 00:07:05,030
from this relationship.

77
00:07:05,070 --> 00:07:10,410
We can see that a trade deficit means the country does not save enough to fund its investment in plants

78
00:07:10,410 --> 00:07:11,730
and equipment.

79
00:07:11,730 --> 00:07:16,200
The additional amount to fund domestic investment must come from foreigners.

80
00:07:16,200 --> 00:07:22,890
So there is a surplus in the capital account to offset the deficit in the trade account equivalently.

81
00:07:22,930 --> 00:07:28,220
The equation is equal to the difference between national income and total expenditure.

82
00:07:28,410 --> 00:07:34,110
You can look at national income as the total domestic production of goods and services and total expenditure

83
00:07:34,440 --> 00:07:37,980
as the total domestic absorption of goods and services.

84
00:07:38,110 --> 00:07:45,440
Is a trade deficit when a country absorbs more than it produces so we can see that in order to reduce

85
00:07:45,440 --> 00:07:51,710
the trade deficit a depreciation of the domestic currency must increase national income relative to

86
00:07:51,710 --> 00:07:58,400
expenditure we can also view this as a requirement that national saving increase relative to domestic

87
00:07:58,400 --> 00:08:05,580
investment in physical capital whether a currency depreciation has these effects depends on the current

88
00:08:05,580 --> 00:08:12,830
level of capacity utilization in the economy when an economy is operating at less than full employment.

89
00:08:12,930 --> 00:08:18,810
The currency depreciation makes domestic goods and assets relatively more attractive than foreign goods

90
00:08:18,840 --> 00:08:20,710
and assets.

91
00:08:20,720 --> 00:08:26,180
The resulting shift in demand away from foreign goods and towards domestic goods will increase both

92
00:08:26,180 --> 00:08:28,890
national income and savings.

93
00:08:28,940 --> 00:08:35,710
This can bring about a reduction in the trade deficit in a situation where the economy is operating

94
00:08:35,710 --> 00:08:36,970
at full employment.

95
00:08:37,000 --> 00:08:43,030
An increase in domestic spending will translate to higher domestic prices which can reverse the relative

96
00:08:43,030 --> 00:08:48,880
price changes of the currency depreciation resulting in a return to the previous deficit in the balance

97
00:08:48,880 --> 00:08:56,060
of trade however there can be another effect at play which is the wealth effect.

98
00:08:56,360 --> 00:09:03,020
The currency depreciation does result in a decline in the value of domestic assets so savers may initially

99
00:09:03,020 --> 00:09:07,050
want to spend less and save more to rebuild wealth.

100
00:09:07,180 --> 00:09:14,110
This can improve the balance of trade initially but as the real wealth of savers increases over time

101
00:09:14,590 --> 00:09:20,530
the positive impact on saving will decrease eventually returning the economy to its previous state and

102
00:09:20,530 --> 00:09:28,400
balance of trade and that concludes this lesson on the relationship between exchange rates international

103
00:09:28,400 --> 00:09:30,720
trade and capital flows.

104
00:09:30,740 --> 00:09:36,330
Admittedly the last part is a bit hard to digest treated as a bonus if you can understand.

105
00:09:36,470 --> 00:09:38,630
So don't spend too much time on it.

106
00:09:39,460 --> 00:09:46,950
And congratulations you've completed this course on economics and you're one step closer to CFA success.

107
00:09:47,200 --> 00:09:52,000
Do head onto the bonus section after this where we have some goodies in store for you.
