Loans

A

A commitment of funds for an agreed upon period of time
Banks make loans to corporations to finance the purchase of capital
They also make mortgage loans to finance the purchase of homes, and personal loans to finance consumer durable goods, such as cars or boats

Q

The nominal interest rate

A

Nominal interest rate on other assets - Nominal interest rate on money (Opportunity cost of holding money)
The interest rate that you earn on currency and chequable deposits is zero
By holding money you forgo the interest rate you would have received
The inflation rate also devalues money, so, the higher the expected inflation rate, the higher is the nominal interest rate

Q

The Short-Run Effect of a Change in the Quantity of Money

A

If the Bank increases the quantity of money, people
will be holding more money than the quantity demanded.
So they buy some bonds. The increased demand for bonds raises the bond price and lowers the interest rat

Q

In the long run, an increase in the quantity of money returns all real variables to their original levels, but changes the price level

A

The price level changes by the same percentage as the quantity of money
The only free variable that is able to respond to a change in the supply of the quantity of money in the long run is the price level
The level adjusts to make the quantity of real money supplied equal to the quantity of real money demanded
Price level changes by the percentage change in the quantity of nominal money

Q

In long-run equilibrium, the Government of Canada increases the quantity of money supplied by 10 percent. The steps that follow are

A

The nominal and real interest rates fall
People borrow and spend more and firms want to do the same
This increases the demand for loanable funds
The increase in demand cannot be met by an increase in supply because the economy is at full employment
Thus there is a general shortage of various goods and services
This forces the price level to rise
This then decreases the real quantity of money
This then raises both the nominal and real interest rates
This then decreases demand and the equilibrium is restored
Thus, the price level has increased by 10 percent but nothing else has changed

61
Q

In this case, PY is GDP (not real GDP) and M is the quantity of money.

A

The equation of exchange= MV=PY

Price level in the long-run=M(V/Y)

62
Q

The equation of exchange can also be expressed as growth rates

A

Money growth rate + Rate of velocity change =Inflation rate + Real GDP growth rate

In the long run, the rate of velocity change is assumed to be zero, so:

Inflation rate= Money growth rate - Real GDP growth rate
In the long-run, the real GDP growth rate equals the potential GDP growth rate.

63
Q

The size of the money multiplier depends on

A

The currency drain ratio (C/D)
The desired reserve ratio (R/D)
Money multiplier = (1 + C/D) ÷ (C/D + R/D)
In our example, C/D is 0.5 and R/D is 0.1, so
Money multiplier = (1 + 0.5) ÷ (0.1 + 0.5)
= (1.5) ÷ (0.6)
= 2.5

64
Q

Foreign currency

A

The money of other countries regardless of whether that money is in the form of notes, coins, or bank deposits.

Q

About the Canadian Dollar Exchange Rate

A

The exchange rate is determined by demand and supply in the foreign exchange market.
The quantity of Canadian dollars demanded in the foreign exchange market is the amount that
traders plan to buy during a given time period at a given exchange rate.

69
Q

The exchange rate influences the quantity of dollars demanded for two reasons

A

Exports effect
Expected profit effect

70
Q

The quantity depends on many factors but the main ones are

A

The exchange rate
World demand for Canadian exports
Interest rates in Canada and other countries
The expected future exchange rate

The law of demand for foreign exchange states that other things remaining the same, the higher the exchange rate, the smaller is the quantity of Canadian dollars demanded on the foreign exchange market.

71
Q

Exports effect

A

The lower the exchange rate, the cheaper are Canadian-produced goods to foreigners,
and the greater the level of exports, the greater the quantity of Canadian dollars
demanded on the foreign exchange market.

72
Q

Expected profit effect

A

The lower the exchange rate, the larger the expected profit from buying Canadian
dollars, and the greater the quantity of dollars demanded on the foreign exchange
market

73
Q

Supply in the Foreign Exchange Market

A

The quantity of Canadian dollars supplied in the foreign exchange market is the amount that
traders plan to sell during a given time period at a given exchange rate.

74
Q

The quantity depends on many factors but the main ones are:

A

The exchange rate
o Canadian demand for imports
o Interest rates in Canada and other countries
o The expected future exchange rate
* The law of supply of foreign exchange states that other things remaining the same, the higher
the exchange rate, the greater is the quantity of Canadian dollars supplied in the foreign
exchange market.

75
Q

The exchange rate influences the quantity of dollars supplied for two reasons

A

Imports effect
Expected profit effect

76
Q

Imports effect

A

The higher the exchange rate, the cheaper are foreign-produced goods to Canadians,
and the greater the level of imports, the greater the quantity of Canadian dollars
supplied on the foreign exchange market.

77
Q

Expected profit effect

A

The higher the exchange rate, the larger the expected profit from selling Canadian
dollars, and the greater the quantity of dollars supplied on the foreign exchange market.

78
Q

Exchange Rate Fluctuations

A

A change in any influence other than the exchange rate on the quantity of Canadian dollars that
people plan to buy brings a change in the demand for dollars and a shift in the demand curve for
dollars.

79
Q

(Exchange Rate Fluctuations)These other influences are

A

Interest rates in Canada and other countries.
o World demand for Canadian exports.
o The expected future exchange rate.

80
Q

Changes in the demand for Canadian dollars

A

World demand for Canadian exports (A RISE IN ALL OF THESE BRINGS A RISE IN DEMAND)
An increase in demand for Canadian exports increases the demand for Canadian dollars

81
Q

Canadian interest rate relative to the foreign interest rate

A

Canadian interest rate – the foreign interest rate = Canadian interest rate differential
The larger the Canadian interest rate differential, the larger the demand for Canadian dollars

82
Q

The expected future exchange rate

A

A rise in the expected future exchange rate increases the profit that people expect to make by holding Canadian dollars, so the demand for Canadian dollars increases today

83
Q

Changes in the Exchange Rate

A

If demand for Canadian dollars increases and
supply does not change, the exchange rate rises.
If demand for Canadian dollars decreases and
supply does not change, the exchange rate falls.
If supply of Canadian dollars increases and
demand does not change, the exchange rate falls.
If supply of Canadian dollars decreases and
demand does not change, the exchange rate rises.

84
Q

World Demand for Canadian Exports

A

At a given exchange rate, if world demand for Canadian
exports increases, the demand for Canadian dollars
increases.

85
Q

Arbitrage

A

is the practice of seeking to profit by buying in
one market and selling for a higher price in another related
market.

86
Q

Arbitrage in the foreign exchange market and international
loans and goods markets achieves four outcomes

A

The law of one price
▪ No round-trip profit
▪ Interest rate parity
▪ Purchasing power parity

87
Q

Canadian demand for imports

A

An increase in the demand for Canadian imports increases the supply of Canadian dollars in the foreign exchange market (SAME)

88
Q

Canadian interest rate relative to the foreign interest rate

A

Inverted interest rate differential effect for the supply of Canadian dollars

89
Q

The expected future exchange rate

A

A fall in the expected future exchange rate decreases the profit that can be made holding Canadian dollars and decreases the quantity of Canadian dollars that people want to hold and the supply of Canadian dollars increases because people want to get rid of them (INVERTED FROM DEMAND)

89
Q

The law of one price

A

If an item is traded in more than one place, the prices will be the same in all places

90
Q

No round-trip profit

A

A round-trip is using currency A to buy currency B and then using currency B to buy currency A
This may involve more stages (using B to buy C and then C to buy A

91
Q

Interest rate parity

A

States that in risk-free transactions, there is no gain from choosing one currency over another

92
Q

Purchasing power parity

A

Means the equal value of money
This is an example of the law of one price
If goods and services are said to cost more in one country than another, the currency of the first country is said to be overvalued
Arbitrage is said to stop this

93
Q

Speculation

A

Trading on the expectation of making a profit.
It differs from arbitrage because that is trading with the certainty of making a profit

94
Q

Exchange rate forecasting differs from weather forecasting in three ways

A

Exchange rate forecasts are hedged with a lot of uncertainty
There are many divergent forecasts
The forecasts influence the outcome

The reliance on exchange rate forecasts can give rise to exchange volatility in the short run
The market fundamentals that influence the exchange rate are world demand for Canadian exports, Canadian demand for imports, and the Canadian interest rate differential.

95
Q

Three possible exchange rate policies are

A

Flexible exchange rate
▪ Fixed exchange rate
▪ Crawling peg

95
Q

Real exchange rate

A

The relative price of Canadian-produced goods and services to foreign-produced goods and services.
RER= (E × P) ÷ PJ

Where E is the exchange rate, P is the Canadian price level, and PJ is the Japanese price level.

The real exchange rate is not 1 and it changes over time.

The exchange rate is: E = (RER × PJ) ÷ P
RER = (E x P)/P.
E = RER x (P/P).

96
Q

flexible exchange rate

A

policy is one that permits the exchange rate to be determined by
demand and supply with no direct intervention in the foreign exchange market by the central
bank.

97
Q

A fixed exchange rate

A

policy is one that pegs the exchange rate at a value decided by the
government or central bank and that blocks the unregulated forces of demand and supply by
direct intervention in the foreign exchange market.

98
Q

Market fundamentals that determine the exchange rate in the long run

A

The real exchange rate
The quantities of money in each economy

98
Q

A crawling peg

A

exchange rate policy is one that selects a target path for the exchange rate with
intervention in the foreign exchange market to achieve that path.

99
Q

balance of payments accounts

A

A country’s balance of payments accounts records its
international trading, borrowing, and lending.

100
Q

There are three balance of payments accounts

A

Current account
2. Capital and financial account
3. Official settlements account

101
Q

The current account

A

records payments for imports of goods and services from abroad, receipts
from exports of goods and services sold abroad, net interest paid abroad, and net transfers
(such as foreign aid payments).

102
Q

The capital and financial account

A

records foreign investment in Canada minus Canadian
investment abroad.

103
Q

The official settlements account

A

account records the change in official Canadian reserves.

104
Q

Official reserves

A

Official reserves are the government’s holdings of foreign currency.
* If Canadian official reserves increase, the official settlements account balance is negative and if
official Canadian reserves decrease, the official settlements account balance is positive.
* The sum of the balances of the three accounts always equals zero.

105
Q

A net lender

A

is a country that lends more to the rest of the world than it borrows from it.

106
Q

net borrower.

A

A country that has a current account deficit and that borrows more from the rest of the world
than it lends to

107
Q

A debtor nation

A

is a country that during its entire history has borrowed more from the rest of the world than is has lent to it.

108
Q

A creditor nation

A

is a country that has invested more in the rest of the world than other countries have invested in it.

109
Q

Current Account Balance

A

The current account balance (CAB) is
CAB = NX + Net interest income + Net transfers
The main item in the current account balance is net
exports (NX).
The other two items are much smaller and don’t fluctuate
much.

110
Q

Financing International Trade

A

he government sector surplus or deficit is equal to net
taxes, T, minus government expenditure on goods and
services G.
The private sector surplus or deficit is saving, S, minus
investment, I.
Net exports is equal to the sum of government sector
balance and private sector balance:
NX = (T – G) + (S – I

111
Q

Net exports

A

is the value of exports of goods and services minus the value of imports of goods
and services.

112
Q

The private sector balance

A

is equal to saving minus investment.
* Net exports is equal to the sum of the government sector surplus and the private sector surplus.

113
Q

The government sector balance

A

The government sector balance is equal to net taxes minus government expenditures on goods
and services.

114
Q

Quantity Supplied and Supply

A

The quantity of real GDP supplied is the total quantity that
firms plan to produce during a given period.
Aggregate supply is the relationship between the quantity
of real GDP supplied and the price level.

115
Q

We distinguish two time frames associated with different
states of the labour market:

A

▪ Long-run aggregate supply
▪ Short-run aggregate supply

116
Q

Long-run aggregate supply

A

is the relationship between
the quantity of real GDP supplied and the price level when
real GDP equals potential GDP
When real GDP equals potential GDP, the long-run aggregate supply curve (LAS) is vertical, meaning potential GDP is independent of the price level.

117
Q

Short-run aggregate supply

A

When the money wage rate, prices of other resources, and potential GDP remain constant, a rise in the price level increases the quantity of real GDP supplied. This relationship is represented by the upward-sloping short-run aggregate supply curve (SAS).

118
Q

Changes in Aggregate Supply

A

Aggregate supply changes if an influence on production
plans other than the price level changes.
These influences include
▪ Changes in potential GDP
▪ Changes in money wage rate (and other factor prices)

119
Q

Aggregate Demand

A

is the relationship between the
quantity of real GDP demanded and the price level.

The quantity of real GDP demanded, Y, is the total amount of goods and services people, businesses, governments, and foreigners plan to buy. It’s calculated by summing consumption expenditures (C), investment (I), government expenditure (G), and net exports (X – M). We study the relationship between the quantity demanded of real GDP and the price level by analyzing how it varies when keeping other factors constant. This relationship is depicted by the aggregate demand curve (AD), which shows the quantity of real GDP demanded against the price level.

120
Q

Changes in Potential GDP

A

When potential GDP increases, both the LAS and SAS
curves shift rightward.
Potential GDP increases if:
The full-employment quantity of labour increases
The quantity of capital (physical or human) increases
An advance in technology occurs

121
Q

Wealth Effect

A

A rise in the price level reduces the quantity of real wealth, prompting people to save more and spend less to restore it. Consequently, the quantity of real GDP demanded decreases. Conversely, a fall in the price level increases real wealth, encouraging higher spending and boosting the quantity of real GDP demanded.

122
Q

International substitution effect

A

Rising prices raise the price of domestic goods relative to foreign goods, leading to increased imports and decreased exports, thereby reducing the quantity of real GDP demanded. Conversely, falling prices increase the quantity of real GDP demanded.

123
Q

Changes in Aggregate Demand

A

A change in any influence on buying plans other than the
price level changes aggregate demand.
The main influences on aggregate demand are
▪ Expectations
▪ Fiscal policy
▪ Monetary policy
▪ The world economy

123
Q

Intertemporal substitution effect

A

Rising prices reduce the real value of money and raise interest rates, decreasing borrowing and spending, and thus real GDP demanded. Falling prices increase the real value of money and lower interest rates, leading to increased borrowing, spending, and real GDP demanded.

124
Q

Expectations

A

Expectations about future income, inflation, and profits affect aggregate demand. Higher expected future income boosts current consumption, raising aggregate demand. A rise in expected inflation makes present purchases cheaper, increasing aggregate demand. Similarly, an increase in expected future profits drives up investment, further increasing aggregate demand.

125
Q

Fiscal Policy

A

Fiscal policy involves government actions like adjusting taxes, transfer payments, and purchasing goods and services to impact the economy. Tax cuts or higher transfer payments raise households’ disposable income, which leads to increased consumption expenditure and aggregate demand.

126
Q

Monetary Policy

A

Monetary policy involves adjusting interest rates and the quantity of money in the economy. Increasing the quantity of money boosts buying power, thereby increasing aggregate demand. Similarly, lowering interest rates stimulates spending, leading to an increase in aggregate demand.

127
Q

The World Economy

A

The world economy affects aggregate demand in two key ways. Firstly, a decline in the foreign exchange rate reduces the price of domestic goods compared to foreign goods, boosting exports, reducing imports, and thus increasing aggregate demand. Secondly, a rise in foreign income increases the demand for Canadian exports, leading to a rise in aggregate demand.

128
Q

Short-run macroeconomic equilibrium

A

occurs when the
quantity of real GDP demanded equals the quantity of real
GDP supplied at the point of intersection of the AD curve
and the SAS curve.

129
Q

inflationary gap

A

The amount by which potential GDP exceeds real GDP

129
Q

The Business Cycle in the AS-AD Model

A

The business cycle occurs due to fluctuations in aggregate demand and short-run aggregate supply, with slow adjustments in the money wage compared to real GDP and potential GDP. Above full-employment equilibrium means real GDP surpasses potential GDP, full-employment equilibrium denotes real GDP equals potential GDP, and below full-employment equilibrium signifies potential GDP exceeds real GDP.

130
Q

Long-run macroeconomic equilibrium

A

occurs when real
GDP equals potential GDP—when the economy is on its
LAS curve.
Long-run equilibrium occurs at the intersection of the AD
and LAS curves.

131
Q

recessionary gap

A

When real GDP is less than potential GDP

132
Q

Fixed Prices and Expenditure Plans

A

Keynesian model describes the economy in the very short
run when prices are fixed.
Because each firm’s price is fixed, for the economy as a
whole:
1. The price level is fixed.
2. Aggregate demand determines real GDP.
What determines aggregate expenditure plans?

133
Q

Expenditure Plans

A

Aggregate expenditure components combine to form real GDP, expressed as Y = C + I + G + X - MY=C+I+G+X−M. Among these components, consumption and imports are influenced by real GDP, establishing a two-way relationship between aggregate expenditure and real GDP.

134
Q

Two-Way link Between Aggregate Expenditure and
Real GDP

A

Other things remaining the same,
 An increase in real GDP increases aggregate
expenditure.
 An increase in aggregate expenditure increases real
GDP.

135
Q

Disposable income

A

is aggregate income or real GDP, Y,
minus net taxes, T.
Call disposable income YD.
The equation for disposable income is
YD = Y – T

136
Q

disposable income

A

disposable income, YD, is either spent on consumption goods, C, or saved, S, forming the equation YD = C + S. The link between consumption expenditure and disposable income, when other factors remain constant, is the consumption function, while the connection between saving and disposable income, under unchanged conditions, is the saving function.

137
Q

Consumption Function

A

As disposable income rises, consumption expenditure increases. Even when disposable income is zero, consumption expenditure remains positive, known as autonomous consumption. Any consumption expenditure beyond autonomous consumption, resulting from an increase in disposable income, is termed induced consumption.

138
Q

Other Influences on Consumption and Saving

A

The other factors that influence consumption and saving
are
1. The real interest rate
2. Wealth
3. Expected future income
A change in any of these factors changes autonomous
consumption and shifts both the consumption function and
the saving function

139
Q

Marginal Propensities to Consume and Save

A

The marginal propensity to consume (MPC) represents the fraction of a change in disposable income spent on consumption. It’s calculated as the change in consumption expenditure (DC) divided by the change in disposable income (DYD) that caused it: MPC = DC ÷ DYD.

140
Q

marginal propensity to save (MPS)

A

The marginal propensity to save (MPS) is the fraction of
a change in disposable income that is saved.
It is calculated as the change in saving, DS, divided by the
change in disposable income, DYD, that brought it about.
That is,
MPS =DS ÷ DYD

141
Q

The MPC plus the MPS equals 1

A

To see why, note that,
DC + DS = DYD.
Divide this equation by DYD to obtain,
DC/DYD + DS/DYD = DYD/DYD
or
MPC + MPS = 1.

142
Q

Consumption as a Function of Real GDP

A

Disposable income changes when real GDP or net taxes change. If tax rates remain constant, real GDP solely influences disposable income, making consumption expenditure a function of real GDP. We employ this relationship to ascertain real GDP when the price level remains fixed.

143
Q

Import Function

A

In the short run, Canadian imports are influenced primarily
by Canadian real GDP.
The marginal propensity to import is the fraction of an
increase in real GDP spent on imports.
If an increase in real GDP of $100 billion increases imports
by $25 billion, the marginal propensity to import is 0.25

144
Q

induced expenditure.

A

Consumption expenditure minus imports, which varies with
real GDP,

145
Q

Aggregate Planned Expenditure

A

With a fixed price level, aggregate demand relies on aggregate expenditure plans. This encompasses planned consumption, investment, government spending, exports, and imports. Real GDP influences planned consumption and imports, increasing with GDP growth. However, investment, government spending, and exports remain unaffected. This relationship can be shown through an aggregate expenditure schedule or curve, detailing planned expenditure at various GDP levels.

146
Q

autonomous
expenditure.

A

The sum of investment, government expenditure, and
exports, which does not vary with GDP,

147
Q

Actual Expenditure, Planned Expenditure, and
Real GDP

A

Actual aggregate expenditure is always equal to real GDP.
Aggregate planned expenditure may differ from actual
aggregate expenditure because firms can have unplanned
changes in inventories.

148
Q

Equilibrium expenditure

A

is the level of aggregate
expenditure that occurs when aggregate planned
expenditure equals real GDP

149
Q

The Multiplier

A

Changes in autonomous expenditure lead to shifts in equilibrium expenditure and real GDP, with the adjustment in equilibrium surpassing the initial change in autonomous expenditure. This amplification effect is captured by the multiplier, which magnifies the impact of autonomous expenditure changes on real GDP. An increase in autonomous expenditure, like investment, boosts aggregate expenditure and real GDP, triggering further induced expenditure and resulting in a larger overall increase in real GDP compared to the initial change in autonomous expenditure.

150
Q

Why Is the Multiplier Greater than 1?

A

An increase in autonomous expenditure induces further
increases in aggregate expenditure.

151
Q

The Size of the Multiplier

A

The size of the multiplier equals the change in equilibrium
expenditure divided by the change in autonomous
expenditure.

152
Q

Business Cycle Turning Points

A

Aggregate planned expenditure is influenced by planned consumption, investment, government spending, and net exports. Changes in real GDP affect planned consumption and imports. When real GDP increases, so does planned consumption and imports. However, investment, government spending, and exports remain unaffected by changes in real GDP.

152
Q

Adjusting Quantities and Prices

A

In the AS-AD model, real firms adjust their prices and production in response to changes in inventories. This adjustment affects both real GDP and the price level, illustrating their simultaneous determination.

153
Q

Aggregate Expenditure and Aggregate Demand

A

The aggregate expenditure curve shows the relationship between planned expenditure and real GDP, holding other factors constant. Similarly, the aggregate demand curve illustrates the relationship between real GDP demanded and the price level, assuming other factors remain unchanged.

154
Q

Deriving the Aggregate Demand Curve

A

When the price level changes, a wealth effect and
substitution effects change aggregate planned expenditure
and change the quantity of real GDP demanded.
