He did his own hunting, found his own shelter, and provided for his own needs. As primitive populations grew and developed, the principle of division of labor evolved. One person was more able to perform some activity than another, and therefore each person concentrated on what he did best. While one hunted, another fished. The hunter then traded his surplus to the fisherman, and thus each benefited from the variety of diet.In today’s complex economic world neither individuals nor nations are self-sufficient. Nations have utilized different economic resources; people have developed different skills. This is the foundation of world trade and economic activity. As a result of this trade and activity, international finance and banking have evolved. For example, the U.S is a major consumer of coffee, yet it does not have the climate to grow any of its own. Consequently, the U.S must import coffee from countries that grow coffee efficiently. On the other hand, the U.S has large industrial plants capable of producing a variety of goods, such as chemicals and airplanes, which can be sold to nations that need them. If nations traded item for item, such as one automobile for 10,000 bags of coffee, foreign trade would be extremely cumbersome and restrictive. But instead of barter, which is the trade of goodswithout an exchange of money, the U.S. receives money in payment for what it sells. It pays for Brazilian coffee with dollars, which in turn can buy textiles from Great Britain, which can then buy tobacco from the U.S. Foreign trade, the exchange of goods between nations, takes place for many reasons. The first, as mentioned above, is that no nation has all of the commodities that it needs. Raw materials are scattered around the world. Large deposits of copper are mined in Peru and Zaire, diamonds are mined in South Africa, and petroleum is recovered in the Middle East. Countries that do not have these resources within their own boundaries must buy from countries that export them.Foreign trade also occurs because a country often does not have enough of a particular item to meet its needs. Although the U.S. is a major producer of sugar, it consumes more than it can produce internally and thus must import sugar.Third, one nation can sell some items at a lower cost than other countries. Japan has been able to export large quantities of radios and television sets because it can produce them more efficiently than other countries. It is cheaper for the U.S. to buy these from Japan than to produce them domestically. According to economic theory, Japan should produce and export those items from which it derives a comparative advantage. It should also buy and import what it needs from those countries that have a comparative advantage in the desired item.Finally, foreign trade takes place because of innovation or style. Even though the U.S. produces more automobiles than any other country, it still imports large quantities of autos from Germany, Japan, and Sweden, primarily because there is a market for them in the U.S.For most nations, exports and imports are the most important international activities. When nations export more than they import, they are said to have favorable balance of trade. When they import more than they export, an unfavorable balance of trade exists. Nations try to maintain a favorable balance of trade, which assures them of the means to buy necessary imports. Some nations base their entire economy on the concept of importing raw materials, processing them into manufactured goods, and then exporting the finished goods. The subsequent profits enable these nations to import the food they need.In addition to visible trade, which involves the import and export of goods and merchandise, there is also invisible trade, which involves the exchange of services between nations.As an example of invisible trade, Brazilian coffee is usually transported by ocean vessels because these steamships are the cheapest method of transportation. Nations such as Greece and Norway and Hong Kong have large maritime fleets, which can provide this transportation service. When an exporter arranges for this kind of transportation, he rents space in the cargo compartment of a ship for one voyage.The prudent exporter purchases insurance for his cargo’s voyage. While at sea, a cargo is vulnerable to many dangers, the most obvious being that the ship may sink. In this event, the exporter who has purchased insurance is reimbursed. Otherwise, he may suffer a complete loss. Thus, insurance is another service in which some nations specialize. Great Britain, because of the development of Lloyd’s of London, is a leading exporter of this service, earning fees for insuring other nations’ foreign trade.Some nations possess little in the way of exportable commodities or manufactured goods, but they have a mild and sunny climate. During the winter, the Bahamas attract numbers of tourists, particularly from the northeastern U.S., who spend money for hotel accommodations, meals, taxes, and so on. Tourism, therefore, is another form of invisible trade.Invisible trade can be as important to some nations as the export of raw materials or commodities is to others. In both cases, the nations earn money to buy necessities.The different kinds of trade that nations engage in are varied and complex, a mixture of visible and invisible trade. Most nations are more dependent on exports than on any other activity. The earnings from exports pay for the imports that they need and want. A nation’s balance of payments is a record of these complex transactions. The two most important categories in any nation’s balance of payments are its visible and invisible trade. A third very important category is investments.Investments are the means by which nations utilize the capital of other nations to build factories and develop mines fro their own industrial base. The railroads of the U.S. and South America were built by British capital. This capital paid for the costs of construction, including materials and the wages of the workers, and the locomotives and freight cars.Investment can have a crucial impact on a nation’s balance of payments. When an investment is made, capital enters a country, enabling it to import manufactured materials to build a new manufacturing plant and to pay workers to build it. Once the plant is operative, it provides both jobs and taxes for the host country and, in time,produces new manufactured goods for export. In this way, investment acts as a catalyst in economic growth for the developed countries, as well as developing countries throughout the world.In subsequent years, an investment should yield a profit. Dividends, sums of money paid to shareholders of a corporation out of earnings, can then be remitted to the investing country. From the perspective of the balance of payments, in the year the investment is made, the host country credits income to its balance of payments, and the investing country records a debit. This is reversed in the following years. The dividends then represent an expense for the host country and income for the investing country.After calculating all of the entries in its balance of payments, a nation has either a net inflow or a net outflow of money. It should be noted that the statistics used in determining a deficit (shortage) or surplus (excess) are inexact; information is reported by a variety of sources, and there are bound to be mistakes and omissions. The statistical difference between these sources is balanced by an entry entitled ―Net Errors and Omissions‖. The final result is either an increase or a decrease in the nation’s reserves.These reserves may be compared to an individual’s saving. For a nation, they are maintained in holdings of gold and official deposits in foreign currencies, such as U.S. dollars, pounds sterling, deutsche marks, and so on. A deficit in the balance of payments can be accommodated by drawing on (removing some of) the reserves, that is, the previous savings. But if a nation’s balance of payments continues in deficit for some time, then the reserves will be insufficient to cover further withdrawals, and additional measures must be taken.The most direct means of correcting a deficit in the balance of payments and having an immediate impact is by reducing imports. This can be accomplished by imposing tariffs, quotas, or both. If successful, the cost of imports rises in the local market, and the imported goods are comparatively more expensive to the consumer than the locally made goods. When a quota is imposed, the quantity previously imported and paid for is reduced.In either case, the net effect is the reduction of the nation’s outflow of money. Other measures may limit invisible trade expenditures. For example, citizens may be prohibited from taking more than a specified amount of money with them when they travel abroad. Capital for investments abroad can be restricted by requiring governmental approval for any new foreign investments.If these measures are insufficient, a country may devalue its currency. This immediately makes imports more expensive and exports more competitive, since the importing country can now pay for the first country’s imports with less of their currency than previously. In time, these advantages are eliminated.Gold, and to a lesser extent silver, have been the traditional reserves. At one time, gold moved freely from country to country, but successive constraints have been imposed in the past 50 years. Today, gold counts as only one form among many in the reserves of a country.Notes1.
