ECO344 - INTERNATIONAL ECONOMICS SUMMARY

Q. Briefly explain the term ―international trade‖.

International trade is the exchange of capital, goods, and services

across international borders or territories because there is a need or want of

goods or services. In most countries, such trade represents a significant

share of gross domestic product (GDP). International trade allows countries

to expand their markets for both goods and services that otherwise may not

have been available domestically. As a result of international trade, the

market is more competitive which results in more competitive pricing which

brings a cheaper product home to the consumer.

Q. Discuss the theory of international trade.

International economics can be divided conveniently into two parts: real

analysis or trade theory, and monetary analysis or international finance.

Real analysis studies the reasons that trade takes place, the implications for

commodity and factor price of changes in real variables (such as the stock of

capital and the supply of labor), the benefits that accrue from international

trade, and the effect of trade restrictions on the welfare of the economy.

Because its focus is equilibrium determination of real trade flows and

welfare, trade theory generally analyzes barter exchange expressed in terms

of a numeraire good. It ignores macroeconomic disequilibrium problems by

assuming the existence of full employment and aggregate trade balance.

Monetary analysis, on the other hand, is concerned with such issues as the

determination of exchange rates and the international transmission of

unemployment and inflation. Often the two branches of international

economics use different methodologies, with trade theory using market-

clearing microeconomic equilibrium processes and international finance

using macroeconomic concepts such as a single aggregate output and price

level, in which there can be shortrun fluctuations. However, this distinction

can easily he overdrawn. In recent years economists have made great strides

in integrating the two approaches by modelling aspects of international

finance, such as the existence of an aggregate trade deficit, as the result of

microeconomic equilibrium processes in which agents trade goods both

across borders and over time.

One question naturally arises: why is it necessary to distinguish trade

between nations from trade between regions, and even from trade between

individual consumers? The basic motivations for all such exchanges are

similar, including differences in tastes and factor endowments. However,

there are some unique features of international trade. First, though it is

reasonable to assume that labor is completely mobile within a country, labor

mobility among countries is severely restricted because of government

regulation and differences in such things as language, religion, and social

customs. Indeed, it is usually assumed in trade theory that labor is

completely immobile among countries. Much of the theory of international

trade also assumes capital to be immobile among countries, though we

thoroughly analyze the implications of capital mobility later in the course of

discussion in this course material. Differences in the degree of factor

mobility are important because they help govern the incentives for and the

implications of trade in commodities.

People in wealthier nations often argue that trade with poorer nations is

harmful because it invites competition from low-wage foreign labor, while

people in poorer countries make the opposite case that trade with countries

with high-level technologies is unfair. These two views are fundamentally

mercantilist in nature, in that they see international trade as taking place

within a fixed-sum game. The gains to one country are accompanied by

losses to another country. This view is wrong because International

exchange, like trade among domestic agents, tends to expand aggregate

incomes in all countries. Indeed, a substantial point of inquiry will be to

investigate the nature of the gains from trade, or the benefits from

international commerce.

Q. Briefly discuss the importance of international trade.

Globally, international trade has grown considerably in recent decades. For

example, over the period between 1963 and 1979, the rate of expansion of

real merchandise exports (that is, the value of exports deflated by changes

in export prices) in the world averaged 11.8 percent per year, a remarkably

high growth rate by historical standards. Indeed, this figure likely

underestimates the true growth in the real volume of exports because

available price data do not adequately account for the marked improvements

in product quality in recent years. At the same time, global growth in real

output, measured by gross domestic product (GDP) in each country,

averaged 6.1 percent per year, also high by historical standards. Thus,

during that period, the world experienced a rapidly rising effective

integration among countries as they become more closely interrelated

through international trade in goods. This trend continued after 1979,

though economic activity grew at markedly slower rates. Over the period

between 1979 and 1991, real export growth averaged 4.4 percent per year,

while real output expansion averaged 2.9 percent per year.

Consider the data in the final two columns of Table 1.1, which show the

ratios of merchandise exports to GDP in 1970 and 1991. These ratios are

often considered to be measures of a nation‘s ―openness‖ to international

trade, though it is more appropriate to interpret them straightforwardly as

indications of the share of national production that is exported. Thus, they

provide rough suggestions of the relative importance of international trade

in aggregate output. In Uganda, as in some other very poor nations, this

export share has fallen considerably over the last 25 years, because of a

dramatic decline in Uganda‘s merchandise exports. On the other hand, with

the exception of Japan, the East Asian economies in our table registered

marked increases in the contribution of their exports to GDP. Most striking

is the experience of China, whose exports rose explosively from 1.8 percent

of GDP to 19.5 percent of GDP. That .Japan‘s share was relatively static

does not mean that export growth was unimportant. To the contrary,

Japan‘s merchandise exports rose sixteen-fold over the period, as did its

GDP. No other developed nation experienced such rapid increases in

economic activity. Thus, at this level it appears that rapid trade growth is

positively related to rapid economic growth.

Q. Discuss the differences between import trade and export trade.

Import means to buy goods and services from a different country to the

home country. Therefore, these goods and services are those which are

produced in a foreign land and are bought by the particular domestic

country. They can be shipped, sent by email, or even hand-carried in

personal luggage on a plane.

When a particular country does not have a particular good or resource, it is

necessary to import that good or resource from another country. Most

countries import raw materials or commodities that are not available within

its borders. The best example of this is how a lot of countries import oil from

the Middle Eastern countries. Therefore, the beneficial party in imports is

the party that exports those products.

Export, on the other hand, is sending goods or services to another country

for sale. As a result, it brings in the foreign income to the domestic country.

The sale of such goods adds to the producing nation‘s gross output. For

example, when a country manufactures excess of some products or if it has

FAQs

What is international trade and its significance?

International trade is the exchange of capital, goods, and services across international borders due to the need or want for goods or services. It significantly contributes to a country's gross domestic product (GDP) and allows nations to expand their markets for products that may not be available domestically. This trade fosters competition, leading to better pricing and more affordable products for consumers.

What are the main theories of international trade discussed?

The document outlines two main branches of international economics: real analysis (trade theory) and monetary analysis (international finance). Real analysis focuses on trade motivations, implications for prices, and welfare effects, while monetary analysis deals with exchange rates and the international transmission of economic variables like unemployment and inflation.

How do imports and exports differ in international trade?

Imports refer to goods and services purchased from foreign countries, while exports are goods and services sold to other countries. Countries often import raw materials or commodities that are not available domestically, whereas they export surplus production or resources, generating foreign income. The distinction is crucial for understanding the dynamics of international trade.

What are the effects of international trade on underdeveloped countries?

International trade can create 'dual economies' in underdeveloped countries, where the export sector thrives while other sectors lag behind. Additionally, these countries may not benefit significantly from trade, as foreign investments often focus on resource extraction for export, neglecting domestic production. This can lead to limited gains from trade and adverse effects on local economies.

What is the role of government policy in international trade?

Government policy plays a crucial role in determining the benefits of trade among countries. Policies can induce specialization in production, affecting economies of scale and resource allocation. However, trade induced by distortions like taxes or subsidies can be welfare-reducing, emphasizing the need for careful policy design to avoid negative impacts on trade dynamics.

What is the concept of gains from trade?

Gains from trade refer to the net benefits that arise from allowing voluntary trading between countries. These gains can result from specialization in production, division of labor, and economies of scale. The document highlights that trade can lead to increased total output possibilities and better allocation of resources, ultimately benefiting all participating countries.

What is the significance of the Stolper-Samuelson theorem?

The Stolper-Samuelson theorem explains the relationship between relative prices of goods and factor rewards, indicating that an increase in the price of a good will raise the return to the factor used intensively in its production. This theorem is integral to understanding how trade affects income distribution among factors of production and is linked to the factor price equalization theorem.
