Introduction
Macroeconomic Equilibrium and
Open Economy
Open economies
• The development of international trade
(volume)
• Trade barriers and restrictions on capital
flows tend to disappear (GATT + WTO
rounds)
• A disequilibrium between imports and
exports

• International trade becomes more
intensive.
• The openess degree measured by
(EX+IM)/GDP is about 73% for Canada
against 23% for Japan.
• Exports need not be equal to imports
-> Capital flows
-> The higher IM-EX, the more the country
dependent on the rest of the world.

• We can distinct capital flows as
– Bank lending (Indirect Finance)
– Portfolio flows (Direct Finance)
– Foreign Direct Investment: Investment of a foreign
firm in a country. FDI is driven by the desire of
entreprises to exploit their intangible property in
markets outside their home country.
• Portfolio flows vary sharply instead of FDI are
quite insensitive to short-run swings in
macroeconomic conditions

• All this evidence suggests that
international economic integration has
hugely increased.
• What are the consequences?
– Growth and development
– Efficiency of government policies
– Contagion and crisis
International Economic
Integration (IEI)
IEI refers to the extent and strength of realsector and financial-sector linkages
among national economies. Real-sector
linkages occur through the international
transactions in goods and services while
the financial-sector linkages occur
through international transactions in
financial assets.
Channels Through Which IEI Can Raise
Economic Growth
International Economic Integration
Direct Channels
 Augmentation of available savings
 Transfer of technology (FDI)
 Development of financial sector
Indirect Channels
 Promotion of specialization
 Inducement for better policies
 Enhancement of capital inflows by
signaling better policies
Higher Economic Growth
International economic integration
could help growth and development
International Economic Integration
and Contagion
International economic integration
Real sector linkages
through exchange of goods
Financial-sector linkages
through international
transactions in financial
assets.
Contagion (crisis, fiscal policy…)
Example
• Imagine two countries: A and B
Expansionary Fiscal
Policy in Country A
Country B’s Income ↑
↑ Demand (country A)
- Domestic goods
- Imports
Country B’s Exports ↑
Example
• Imagine A and B are developing countries with
common features (GDP per capita, inflation, …).
• You have in your bonds portfolio some bonds of
Country A government’s debt and some of
Country B government’s debt.
• Country A’s government says that the
government debt cannot be reimbursed, what do
you do?
Questions of International Finance
• Why international trade and international capital
flows?
• What are the consequences of international
economic integration on production (flows of
inputs)? Consumption (flows of goods)?
• How international economic integration changes
the way monetary and fiscal policies affect
economies?
• How do crisis appear and spread?
Reminder about Macroeconomic
Equilibrium in an Open Economy
Readings:
Macroeconomics, N. Gregory
Mankiw (Harvard U.), chapter 5.
In an open economy,
• Spending need not equal output:
Y≠C+I+G
• Saving need not equal investment
S≠I
• The financial sector
channels funds from net
lender-savers to net
borrower-investors
• Because financial sector
can redirect surplus
funds, leakages and
injections of each sector
need not balance
– I ≠S
– G ≠T
– Im ≠ Ex
Preliminaries
C C d C f
I Id If
G G d G f
superscripts:
d = spending on
domestic goods
f = spending on
foreign goods
EX = exports =
foreign spending on domestic
goods
IM = imports = C f + I f + G f
= spending on foreign goods
Preliminaries, cont.
NX = net exports ( the “trade balance”)
= EX – IM
• If NX > 0,
country has a trade surplus
equal to NX
• If NX < 0,
country has a trade deficit
equal to – NX
GDP = expenditure on
domestically produced g & s
Y  C d  I d  G d  EX
 (C  C f )  (I  I f )  (G  G f )  EX
 C  I  G  EX  (C f  I f  G f )
 C  I  G  EX  IM
 C  I  G  NX
The national income identity
in an open economy
Y = C + I + G + NX
or,
NX = Y – (C + I + G )
domestic
spending
net exports
output
International capital flows
• Net capital outflows
= S –I
= net outflow of “loanable funds”
= net purchases of foreign assets
the country’s purchases of foreign assets
minus foreign purchases of domestic
assets
• When S > I, country is a net lender
• When S < I, country is a net borrower
Another important identity
NX = Y – (C + I + G )
implies
NX = (Y – C – G ) – I
=
S
– I
trade balance = net capital
outflows
Long-run Equilibrium
• An open economy
model :
– Two countries
Country A
SA,IA
Country B
SB,IB
IA+IB=SA+SB
– Small open economy

Assumptions re: capital flows
a. domestic & foreign bonds are perfect
substitutes (same risk, maturity, etc.)
b. perfect capital mobility:
no restrictions on international trade in
assets
c. economy is small:
cannot affect the world interest rate,
denoted r*
a & b imply r = r*
c implies r* is exogenous
Investment:
The Demand for Loanable Funds
r
Investment is still a
downward-sloping function
of the interest rate,
but the exogenous
world interest rate…
r*
…determines the
country’s level of
investment.
