Answers to the questions in Exercise No. 24
yuestion L: What are the results of internationa]
trade?
ans wer
When (countries start to trade with one another, they are capable of enjoying a wide range of producta, which are otherwise denied to them if they themselves are unable to produce. For instance, Ceylon produces tea, Brazil coffee, Malaya tin, Hong Kong textiles, and Australia mutton: Because of international trade aach country is able to have the exports of the other countries. Thus Hong Kong can sell her textiles to foreign countries and get in return, tea, coffee," tin. and mutton.
We know that Hong Kong can produce textiles 28 well as grow rice. Since Hong Kong has a greater comparative advantage in manufacturing than in farming, it is wise for her to specialize in manufacturing and give up farming, but this is impossible if international trade does not exist, since to do so, Hong Kong would not have any rice. But as it is, countries like Thailand and China are chief rice suppliers. Hong Kong can therefore rely on them for the supply of rice.
The ability of one country to rely on ovner countries for what the country does not herself produce has given rise to widespread adoption of regional specialisation which in turn resulta ins falan increase in the world total output of
commodities;
(b) a greater quantity and wider range of goods
for each country.
inotner resuit arought about by countries when. they start to trade with one another is that countries have learnt to live with each other. as peaceful neighbours, since each country has to depend on the rest of the world for many products.
International trade also helps to raise the. standard of living, since most people can now enjoy the goods from countries far and near. It also enable labour to be used more productively and
economically,
On the unfavourable Bide, international trade may encourage one country which is more economically advanced to take advantage of another country which is undeveloped. This exploitation is the result of the former country's imposition of terms of trade which are unfavourable to the other country.
International trade encourages each country to specialize in one industry or primary production only. This is bad because every country should be economically active in many industries, and this can enable a greater diversity of jobs to exist in the pountry for the people to chopse, Specializing in one industry is very risky like a person putting all the eggs in one basket.
When countries start to trade with one another, every country gradually becomes a keen competitor. Countries that are economically and socially weak lose their markets to the more advanced countries. That countries cannot, in actual fact, complete on
fair basis is one drawback of international trade.
