Global imbalances
Lecture outline
Global imbalances- definition and measures
Factors and sources of the imbalances
Resolution possibilities
Global imbalances-definition
External inequilibria in systemically
important economies, which pose risks to
the functioning of the global economy
The risks: destabilization of the
international monetary system, financial
crises, protectionism
Global imbalances- elements
Current account imbalances- majorly the
difference between exports and imports
Net foreign assets imbalances- the
difference between the value of the assets
of a country abroad and the value of the
domestic assets owned by foreigners

Measures of the global imbalances
(1)
Current account = Net foreign assets – the value
of central bank interventions
The current account deficit influences the
foreign debt of the economy deficit
accummulation leads to increasing foreign debt
levels
The value of the foreign debt depends on the
valuation of assets and liabilities- exchange rate
changes can influence the value of the debt!!!
Measures of the global imbalances
(2)
Current account imbalances- in a specific
time period
International investment position- a
measure of net foreign asstes in a specific
time period
Foreign reserves- indirect measure of
distortions

The factors of the global
imbalances
Structural factors
Cyclical factors
Cyclical factors
Short-term global demand
Asset prices- inluencing foreign debt levels
Business cycles induced by productivity shocks
investment increase increased imports current
account deficit
Public savings the fiscal stance influences short-term
demand
Oil prices changes higher prices lead to higher
values of imports and exports
Structural factors
Long-term trends
The Lucas paradox
The long-term decrease of savings
Market structures and the share in global
production
The Lucas paradox
Capital flows from developing countries to
developed countries despite the fact that
the second ones have higher levesl of
capital per worker
The reasons for occurrence of the
Lucas pradox
Risk premium in catching –up countries
Capital flow restrictions
Underdeveloped financial markets in
developing countries
FDI flows to emerging countries, portfolio
investment flows to developed countries
Other structural factors
The long-term decrease of savingsbusiness cycle moderation in the USA
The increased share of the USA in the
global output due to productivity growthexpectations of a continued faster growth
drive the US current account deficit
The sources of the unequilibrium (1)
Competing theories
International financial integration
The concept of the Bretton Woods II system
Export oriented exchange rate policy strategies
in Asian countries
Twin deficits
Production effectivity increase in the USA
Global savings glut
International financial integration
International financial integration occurs if all market
participants have equal access to the instruments
traded and face the same set of rules while being active
on the market
The liberalisation of capital flows enabled financial
integration
Twin deficits
The budget deficit in the USA is
accompanied by the deficit of the current
account
The increase of government spending
causes the growth of demand and
increases imports
Exchange rate policies
Exchange rate policies supporting exports in
Asian countries
Central bank interventions preventing currency
appreciation accumulation of large foreign
reserves
The inflow of foreign savings to the American
market the decrease of American interest
rates fuelling American demand
Bretton Woods II
Dooley et al. (2003; 2004; 2005)
The global economy can be portrayed as:
USA as a center
The trade region-Asia- fixed exchange rates,main
market players are central banks and governments
The capital region- Europe, Canada, Australia,floating exchange rates, main market players are
private investors- a neutral region in terms of
imbalances
Bretton Woods II
Underdeveloped financial market in Chinait is easier to allocate the Chinese savings
abroad
The financing of the US deficit ad
infinitum is profitable for China due to
increased exports
Permanent increase of production
effectiveness in the USA
Increase of effectiveness higher rates
of returns on the American asset market
FDI- net negative inflow and decreasing
purchase of American stock counterdicts
the hypothesis of increased effectiveness
– it was only valid until the late 90-ties
Global savings glut
USA as the consumer of last resort- competing explanation to the
Bretton Woods II
Factors:
Restructuring of enterprises profits increase -> increased
savings in the sector of enterprises
The increase of oil prices- increased value of savings in oil
exporting countries
A high propensity to savings in Asian countries and labour
force migration increased savings in the destination
countries
A global savings glut?

Potential resolution
Setser,Obstfeld, Rogoff – the deficit can
not be maintained ad infinitum
versus
Maintainance of the Bretton Woods II
Maintainance of Bretton Woods II
The credibility of USD- investors believe in maitaining of
the current exchange rate policy i.e. large interventions
of the Chinese central banks
No significant difference in the short term and long term
interest rates reflects the expectations of the status quo
Maintainance of the Chinese exchange rate policy –
long term cost of production restructuring
Reluctance to increase US savings
The collapse of Bretton Woods II
Reluctance of Asian central banks to increase reserves
The cost of reserve maintainance- the appreciation of the remninbi
increases the value of liabilities and decreases the value of the
assets held in USD
The costs of interventions- high levels of reserves cause credit
expansion and inflationary pressure despite sterilization
Cost for Chinese state-owned banks- the necessity to purchase low
premium government bonds the necessity to recapitalize banks
The Chinese manufacturing is to a large extent foreign-owned and
its production is consumed dometically
The trade region is very differentiated- no common policies
Mitigation of the imbalances
Exchange rate adjustments
Strenghtening of the supply-side of the
deficit countries
Ajustment of the asset prices
International cooperation- a consensus
has to be reached by the main market
players
The global imbalances and
financial stability
The global imbalances impact negatively
the financial stability
The international monetary system does
not fulfill its functions properly i.e.
impedement of the exchange rate stability
function, liquidity provision function etc.
The global imbalances are blamed as one
of the reasons for the latest financial crisis
The role of the international
currency
“Exorbitant Privilege”
USD as the main reserve currency
Differences in the interest on US assets and
liabilities
USA possess profitable assets in the form of FDI
and stocks, US liabilities are low yield banking
deposits and bonds
The need of cooperation
The resolution can not be carried out by single
countries- the need of global cooperation
The willingness to maintain the inequilibrium
depends on the features of the economies

Public balance
