B416: The Evolution of Global Economies
Lecture 1 : Module Aims, Outcomes & Assessment;
Introduction to Global Economics; Riccardo’s Comparative Advantage
Module Aims• This module aims to introduce learners to the major issues and influences in
the international economy over the past 150 years.
• Understanding the patterns of economic cycles and the causes of growth and recession is an important aim of this course.
• Putting into perspective the extreme economic booms and busts of the past will enable learners to analyse contemporary events in a historically relevant context, and enable learning from past events to be applied to challenges which present themselves today.
• An important objective of this module will be to identify the role of national and institutional economic policies, in combination with a geographical context, to explain key changes in the evolution of the global economy.
• The module aims to give learners an understanding of the causes and impact of ideological, political and socio-economic change on nations, and to enable appropriate use of economic analysis from understanding of key events in the past.
• Comparative Advantage & Riccardian Economics 2
Module OutcomesBy the end of this module, students should be able to:• Understand the foundations of industrialisation and the
drivers of economic growth.• Understand critical points in time and importance of the
evolutionary changes in the international and global economy during the past 150 years.
• Apply constructive critical analysis to, and interpretation from, economic history and consider its relevance to contemporary issues.
• Assess the economic circumstances, theories and principles that were drivers of economic development and growth for specific nations, and barriers to growth for other nations.
• Understand the causes and effects of ideological, political and socio-economic transitions on nation’s economies.
• Demonstrate appropriate use of economic analysis from understanding of key events in the past. 3

Learning Outcomes
By the end of this lecture, you should understand the following:
• We present basic information on the world economy
• Countries are ‘big’ measured by area, population, or income
• Income can be measured as Gross Domestic Product or Gross National Product; the difference is based on nationality of ownership of production factors:
• GDP + net receipts of factor income = GNP
• For most countries the difference (GDP – GNP) is small (but not, e.g. for small oil-rich countries)
• Using exchange rates to compare income levels in different countries underestimates income in developing countries; it is better to use Purchasing Power Parity (PPP) rates to correct for price differences.
• We can distinguish two waves of globalization, both for trade flows and capital flows.

Scope of Global Economics• What is international economics about?• International trade topics
– Gains from trade, explaining patterns of trade, effects of government policies on trade
• International finance topics– Balance of payments, exchange rate determination, international
policy coordination and capital markets
• International trade versus finance
• International economics is about how nations interact through:
– trade of goods and services, flows of money, and investment.
• International economics is an old subject, but continues to grow in importance as countries become tied more to the international economy.
• Nations are now more closely linked than ever before.

Concluding remarks The World Economy
• Large countries land: Russia, China, Canada, USA• Large countries population: China, India• Large countries income: USA, Japan, Germany, UK, France• Large countries income PPP: USA, China, Japan, India• Price differences (at exchange rates) between countries
can be large for non-traded goods (no arbitrage opportunities)
• Deviations GDP – GNP relatively small for most countries• Large trade flows within Europe• Deviations Exports – Imports can be relatively large• Global per capita income levels increased fast last 200
years• Two waves of globalization, both for trade and capital
flows

David Ricardo (1772-1823)
“When a country can either import a commodity or produce it at home, it compares the cost of producing at home with the cost of procuring from abroad; if the latter is less than the first, it imports.”
Page 23
Overview Ricardian (classical) model
• Technology differences between countries are the driving force behind international trade flows
• Relative (or comparative) differences are crucial, not absolute differences
• Absolute differences are important for determining a country’s welfare level
• The production possibility frontier summarizes the state of technology and the available factors of production in final goods space
• Trade flows increase welfare (technology gains from trade)

• Trade flows increase welfare (technology gains from trade)
Page 25
Assumptions of the Ricardian technology model
• Two countries (EU and Kenya)• Two final goods (Food and
Chemicals)• One factor of production (Labour)• Constant returns to scale production functions• Perfect competition• Labour is mobile between sectors, but not between
countries• Costless trade in final goods (no impediments to
trade)• Technology differs between countries
• General (example)
Page 26
Technology differences between countries
Production technology is summarized in a productivity table:
Labour units required to produce one unit of output
Food Chemicals
EU 2 8
Kenya 4 24
The EU technology is more productive for both goods
The EU has an absolute advantage in Food production: it
requires less labour (2 units instead of 4)
The EU also has an absolute advantage in Chemicals
production: it requires less labour (8 units instead of 24)
Page 27
Comparative advantage: productivity method
Labour units required to produce one unit of output
Food Chemicals
EU 2 8
Kenya 4 24
• The EU is twice as productive in the Food sector (4/2 = 2)
• The EU is three times as productive in the Chemicals sector
(24/8 = 3), so
The EU has a comparative advantage in Chemicals, and
Kenya has a comparative advantage in Food
Page 28
• An extra unit of Chemicals needs 8 labour in the EU
• This labour could have made 8/2 = 4 units of Food; the
opportunity cost of Chemicals production in the EU is 4 Food
• An extra unit of Chemicals in Kenya needs 24 labour
• This labour could have made 24/4 = 6 units of Food; the
opportunity cost of Chemicals production in Kenya is 6 Food
Comparative advantage: opportunity cost method
Labour units required to produce one unit of output

Kenya in Food
Page 29
Production possibility frontier (ppf)
Definition: all possible combinations of efficient production points of final goods, given the available factors of production and the state of technology;
note that:• It is a technical specification: the ppf does not depend on the type of market competition• The ppf depends on the available factors of production: if, e.g., more labour becomes available more goods can be produced• The ppf depends on the state of technology: if new techniques become available, output increases with the same use of inputs
Page 30
The ppf is a straight line in the Ricardian modelLabour units required to produce one unit of output
Food Chemicals
EU 2 8
Kenya 4 24
• Suppose the EU has 200 units of labour available and Kenya has
480 units available (remember: it is just an example)
• If all workers in the EU produce only Food, the EU can make
200/2 = 100 Food (and 0 Chemicals)
• If all workers in the EU produce only Chemicals, the EU can make
200/8 = 25 Chemicals (and 0 Food)
• Similarly, if all workers in Kenya produce Food total output is
480/4 = 120 Food (and 0 Chemicals); if they all produce Chemicals
total output is 480/24 = 20 Chemicals (and 0 Food)
Page 31
Concluding remarks Ricardian (classical) model
• Technological differences between countries are the classical driving force for international trade flows.
• Only comparative costs, not absolute costs, are important for determining the direction of trade flows.
• Absolute costs are important for determining a country’s welfare level.
• Allowing for more countries and more goods is easy, allowing for more than one factor of production is not (see neoclassical model).
