4. 1.1 Importance of International Economics
Economic Interdependence
Globalization of Economic Activities
International Competition
Consequences of Increased Openness

5. Economic Interdependence
It means that in today’s world, no nation exists in economic isolation.
All aspects of a nation’s economy-its industry, service sectors,
levels of income and employment , living standard-are linked to the
economics of its trading partners. This linkage takes the form of
international movements of goods and services, labor, business
enterprise, investment funds, and technology.
Facts: After World War Ⅱ,USA was economically and politically the
most powerful nation in the world, a situation expressed in the saying,
“When USA sneezes, the economies of other nations catch a cold.”
Then EEC was formed in 1950s, international corporations in 1960s,
OPEC in 1970s.
Conclusion: In recent years, the character of global economic interdependence has become much more sophisticated.

6. Globalization of Economic Activities
It means that national economies rely on international trade in
overall economic activity . World trade expand faster than world
output in the last 50 years by a significant margin.
Reasons:
Technological Change
Technological innovation led to the increase of productivity, and the
advances in transport technology brought people and enterprises closer
together so that the boundary of tradable goods and services has been
greatly extended.
Continuing liberalization of trade and investment
It led to more and more companies to globalize production structure
through investment abroad.

12. Globalization of Economic Activities
Present Situation: Slower global economic growth in 2007;
continued robust growth in developing countries; insufficient
employment growth; higher oil price crisis; current-account
Imbalances; merchandise trade imbalance; global imbalance
widening further; term of trade. In addition: net financial transfer;
net international investment.
China foreign trade relationship: more dispute with EU and USA;
FDI in China.

25. International Competition
International Competitiveness: It is a hot issue these days.
Intense debate has focused on how firms based in a
particular nation can create and maintain competitiveness
against the world’s leaders in a particular industry.
Firm (Industry) Competitiveness
Competitiveness refers to the extent to which the goods of a firm or
industry can compete in the market place; this competitiveness
depends on the relative prices and qualities of products.
A Nation’s Competitiveness
National competitiveness refers to the achievement of high productivity
of its employed resources and the increasing of living standard for its
people.

26. Consequences of Increased Openness
To curtail inflationary pressures at home (e.g. U.S.dollar)
To increase constraints on those sectors which facing intense foreign competition (e.g. Wage concession)
To reduce or eliminate the crowding out of private investment
To make the domestic economy vulnerable to disturbances initiated overseas (e.g. Skyrocketing gasoline prices of 2000)

27. Conclusion: Need for macroeconomic coordination policy
International policy coordination can facilitate an orderly adjustment of the global imbalances while minimizing the economic growth costs (United Nations, International Monetary Fund, World Bank).
-A new Plaza agreement: the Group of Twenty(20Group, including industrial and emerging-market economies)
-Cross-country effects of national policies: The national policies can’t be considered in isolation but need to be seen in the context of the cross-border spillover effects they give rise to by decreasing the barriers to trade and capital flows.

28. Conclusion: Obstacles for macroeconomic coordination policy
the urgency of adjusting the imbalance
the current position of economies
domestic interest groups
perceived lack of effective policy instrument

29. Conclusion: What can be done?
To develop a consensus on common goals through international consultations with outside mediation
To enhance the context for mediation and the perceived legitimacy of the mediator
To address commitment problems by using multi-year schedules for policy adjustment
To initiate systemic reforms in the field of international monetary and financial affairs for a long-run solution

30. 1.2 International Trade and the Nation’s Standard of Living
Measure of the economic relationship among nations
Close relationship between international trade and the Nation’s standard of living
Conclusion:
International trade is of very importance either for
small countries or large countries.
(see the following data)

31. Measure of the economic relationship among nations
Interdependence Degree: it is given by the ratio of their
imports and exports of goods and services to their gross
domestic product (GDP).
GDP: It refers to the total value of all goods and services
produced in the nation.
The economic interdependence among nations are in general
measured by the more rapid growth of world trade than world
production.

35. 1.3 The Subject Matter of International Economics
International Trade Theory
International Trade Policy
International Monetary Theory
International Monetary Policy
Major Economists’ Theory in International economics ( Adam Smith, David Ricardo, John Stuart Mill, Alfred Marshall, John Maynard Keynes, and Paul Samuelson)

36. International Trade Theory and Policy
International trade theory: it analyzes the basis of trade , the
gains from trade, the patterns of trade.
International trade policy: It examines the reasons for and the
effects of trade restrictions and new protectionism.
International economics: It deals with the economic and
financial interdependence among nations. It analyzes the flow
of goods, services, payments, and monies between a nation
and the rest of the world, the policies directed at regulating
these flows, and their effect on the nation’s welfare. At the
same time the economic and financial interdependence is
affected by the political, social, cultural and military relations
among nations.

37. 1.4 Purpose of International Economic Theories and Policies
Theories are used to examine the basis for and the gains from trade, the reasons for and the effects of trade restrictions; also examine the effectiveness of macroeconomic policies under different types of international monetary arrangements or monetary systems.
Policies are used to direct at regulating the flows of international payments and receipts, and the effects of these policies on a nation’s welfare and on the welfare of other nations.

38. 1.5 Current International Economic Problem
Trade Protectionism in Industrial Countries
Excessive Fluctuations and Large Disequilibria in Exchange Rates
Financial Crisis in Emerging Market Economies
High Structure Unemployment and Slow Growth in Europe and Stagnation in Japan
Job Insecurity from Restructuring and Downsizing in the United States
Restructuring Problems of Transition Economies
Deep Poverty in Many Developing Countries

39. 1.6 Organization and Methodology of the Text
Part Ⅰ(Chapter 2-7)
It deals with international trade theory. Chapter 2 comparative
advantage theory, Chapter 3 basis and gains from trade,
Chapter 4 equilibrium –relative prices, Chapter 5 Heckscher-
Ohlin theory, Chapter 6 new trade theories, Chapter 7 growth
and Trade.
Part Ⅱ(Chapter 8-12)
Chapter 8 tariffs, Chapter 9 non-tariffs trade restrictions,
Chapter 10 economic integration, Chapter 11 international
trade on the impacts of economic development, Chapter 12
international resource movements and multinational
corporations.

40. Part Ⅲ (Chapters 13-15) It deals with the balance of payments, foreign exchange markets, and exchange rate determination. A clear grasp of these three chapters is crucial for understanding Part Four, which focuses on the adjustment to balance-of-payments disequilibria and open-economy macroeconomics. Chapter 13 deals with the measurement of a nation’s balance of payments. Besides presenting the theory, Chapter 14 also examines the actual operation of foreign exchange markets and therefore is of great practical relevance to students of international economics, particularly business majors. Chapter 15 deals more closely with some of the monetary and financial determinants of exchange rates and the reason for exchange rate volatility

41. Part Ⅳ(Chapter 16-21)
It examines the various mechanisms for adjusting balance-of-
payments disequilibria, which are often referred to as open-
economy macroeconomics. Chapter 16 covers the adjustment
mechanism that operates by changing the relationship between
domestic and foreign prices, while Chapter 17 examines the
income adjustment mechanism and presents a synthesis of the
automatic adjustment mechanisms. Chapter 18 and 19 deal with
adjustment policies and open-economy macroeconomics
proper. Chapter 20 compares fixed versus flexible exchange
rates, it examines the European Monetary System, and it
discusses international macroeconomic policy coordination.
Finally, Chapter 21 examines the operation of the international
monetary system over time, especially its present functioning ,
and it offers possible solutions for the major international
economic problems facing the world today.

77. Exercises
How do international economic relations differ from interregional
economic relations?
In what way are they similar?
Nations usually impose restrictions on the free international flow of
trade, services and factors. Differences in language, customs and laws
also hamper these international flows. In addition, international flows may
involve receipts and payments in different currencies, which may change
in value in relation to one another through time.
This is to be contrasted with the interregional flow of goods, services and
factors which face no such restrictions as tariffs and are conduced in
terms of the same currency, usually in the same language, and under
basically the same set of customs and laws.

78. (2) Both international and interregional economic relations involve the overcoming of space or distance. Indeed, they both arise from the problems created by distance. This distinguishes them from the rest of economics, which abstracts from space and treats the economy as a single point in space, in which production, exchange, and consumption take place.

79. Exercises Can you think of some ways of by which a nation can gain
at the expense of other nations from trade restrictions?
A nation can subsidize exports of the commodity to other nations until it drives the competing nation’s industry out of business, after which it can raise its price and benefit from its newly acquired monopoly power.

80. Exercises
When the value of the U.S. dollar falls in relation to the currencies of
other nations, what do you think will happen to the quantity of U.S.
(1) imports?
(2) exports?
(1) Imports become more expensive for Americans and so they would purchase a smaller quantity of imports. (2) U.S. exports become cheaper for foreigners and so they would purchase a greater quantity of U.S. exports.
