,Introduction
2 parts of economics
- ‘real’ (2 6)
- ‘monetary’ (710)
1. Globalization: the statics of globalization (an overview)
1.1. Globalization
What is it?
= increased trade & factor migration
Economical point of view
What do you have in an economy?
Production process
INPUT = factors of PRODUCTION OUTPUT
production PROCES
• Labour • Labour • goods
• Capital (people) • services
• Nature working with
capital
(machines)
International economics POV:
- Different inputs and outputs start crossing borders
• International trade (exchanging outputs)
• International factor migration (trading input)
have increased in size = globalization
more and more economic transaction
TABLE: aspects of different periods in the recent history ( GLOBALIZATION IN
HISTORICAL PERSPECTIVE)
Remarks:
- Before the first world war: already globalization
- Population grow: population grow very fast (faster than before) after WW2
o GDP grows => we become richer
o Per capita? If growth of population > GDP growth not getting richer
people got richer during the 2 stages of globalization
- Trade growth: (output)
o Higher than capita growth of income => world economy has become more open
= globalization
o Golden 60’ies – 70’ies: trade growth is the highest
INTERNATIONAL ECONOMICS 5
, - Migration
Input: labor
o Net immigration into typical immigration economies
Globalization: borders are open
Input: capital
FDI = Foreign Direct Investment
= a foreign company buys/builds a company in Belgium = DIRECT investment
Wants to control management of the company
≠ foreign investor buying shares in a Belgian company = PORTFOLIO investment
Wants money back, don’t want direct connection with the management
Causes of globalization
- Less barriers (tariffs, regulation, …)
= matter of government policy
o Decreased tariffs: tax on import
Regional: EU
Worldwide basis:
GATT (General AgreementCOMMUNICATION
on Tariffs and Trade & TRANSPORT
WTO (World Trade COSTS IN 1990 US$
Sea freight (per Air transport Phone call (3 Information
Organization (1955)) ton) (per 100
passenger mile)
min. New York –
London)
processing
(processing cost;
countries get together to lower 1980 = 100)
the barriers of international trade
1920 95
1930 60 68 245
- Less transportation and transaction 1940 63 46 189
1.2.1. Size of trade
WORLD TRADE IN GOODS & SERVICES Crisis 2009: drop
(EXPORTS VALUE, bn $) 2014: up
2016: drop
2008 2009 2014 2016
changes in value can be result of
Goods 16160 12555 19005 15955
- Change in volume
Services 3948 3520 5078 4807 Or/and
- Change in price
value = volume x price
Evolution of the goods export in volume
(number of cars, shoes etc. that are
exported)
LONG TERM TENDANCY
Upwards
REAL EVOLUTION (black)
Upwards, but shows drop
versus value
INTERNATIONAL ECONOMICS 6
, Change in volume
Two causes of discrepancy Commodity (oil, petrol, metal, food and
beverages etc.)
1. Declines in commodity prices - Value- drop (prices fall)
Appreciation US dollar:
Exchange rate = nominal effective
exchange rate
= US <-> UK <-> EU <-> Switzerland
<-> …
2. Appreciation of US dollar weighted (by using trade volume)
average of the movements in the
exchange rate of the currencies of the
countries you are dealing with
Effective exchange rate:
- Black: US -> increasing
(strong $)
Others have been decreasing
1.2.2. Openness = globalization
The more open you are, the more globalized you are
(𝑒𝑥𝑝𝑜𝑟𝑡𝑠 + 𝑖𝑚𝑝𝑜𝑟𝑡𝑠)
=
(𝑔𝑑𝑝 𝑥 2)
Compare countries: ex: one country is more open than another
Evolution in time:
Long term: openness increases
- Short term: trade more volatile than gdp
Openness 2016
450,00
(GDP = 100) 400,00
= Gross Domestic Product 350,00
300,00
250,00
200,00
Bigger countries: very 150,00
limited openness ratio 100,00
50,00
0,00
Remarks:
- Ratio > 100%
o How do you export more than you have produced?
▪ You can export goods that you have imported first
INTERNATIONAL ECONOMICS 7
, Evolution of openness
Graph op globalization
Trade is growing faster than GDP
RED: world GDP growth
Blue: trade volume changes => more
erratic
Trade moves up and down faster than
GDP
When international trade increases faster than international production
more openness
= aspect of globalization
Right measure for openness
- Numerator: trade is counted as total value (average of exports & imports)
- Denominator: GDP = added value
- Cf. global supply chains: fragmentation of production = aspect of globalization
o Each time an intermediate good crosses the border it counts in the numerator
Ex:
1. battery for iPhone is exported to a country to be assembled
2. parts of the iPhone (incl. battery) are exported again
3. the iPhone ready is exported again to another country
o Thus: the more fragmentation = the more double counting
Now: more ‘global value chains’
