I chose to answer this question the trade organizations such as the World Trade Organization (WTO), North American Free Trade Agreement (NAFTA), and the European Union (EU). “WTO”

The Global Market Place

Globalization of Markets and Competition: Trade is increasingly global in scope today. There are several reasons for this. One significant reason is technological—because of improved transportation and communication opportunities today, trade is now more practical. Thus, consumers and businesses now have access to the very best products from many different countries. Increasingly rapid technology lifecycles also increases the competition among countries as to who can produce the newest in technology. In part to accommodate these realities, countries in the last several decades have taken increasing steps to promote global trade through agreements such as the General Treaty on Trade and Tariffs, and trade organizations such as the World Trade Organization (WTO), North American Free Trade Agreement (NAFTA), and the European Union (EU).

Stages in the International Involvement of a Firm. We discussed several stages through which a firm may go as it becomes increasingly involved across borders. A purely domestic firm focuses only on its home market, has no current ambitions of expanding abroad, and does not perceive any significant competitive threat from abroad. Such a firm may eventually get some orders from abroad, which are seen either as an irritation (for small orders, there may be a great deal of effort and cost involved in obtaining relatively modest revenue) or as "icing on the cake." As the firm begins to export more, it enters the export stage, where little effort is made to market the product abroad, although an increasing number of foreign orders are filled. In the international stage, as certain country markets begin to appear especially attractive with more foreign orders originating there, the firm may go into countries on an ad hoc basis—that is, each country may be entered sequentially, but with relatively little learning and marketing efforts being shared across countries. In the multi-national stage, some efficiencies are pursued by standardizing across a region (e.g., Central America, West Africa, or Northern Europe). Finally, in the global stage, the focus centers on the entire World market, with decisions made optimize the product’s position across markets—the home country is no longer the center of the product. An example of a truly global company is Coca Cola.

Note that these stages represent points on a continuum from a purely domestic orientation to a truly global one; companies may fall in between these discrete stages, and different parts of the firm may have characteristics of various stages—for example, the pickup truck division of an auto-manufacturer may be largely domestically focused, while the passenger car division is globally focused. Although a global focus is generally appropriate for most large firms, note that it may not be ideal for all companies to pursue the global stage. For example, manufacturers of ice cubes may do well as domestic, or even locally centered, firms.

Some forces in international trade. The text contains a rather long-winded appendix discussing some relatively simple ideas. Comparative advantage, discussed in more detail in the economics notes, suggests trade between countries is beneficial because these countries differ in their relative economic strengths—some have more advanced technology and some have lower costs. The International Product Life Cycle suggests that countries will differ in their timing of the demand for various products. Products tend to be adopted more quickly in the United States and Japan, for example, so once the demand for a product (say, VCRs) is in the decline in these markets, an increasing market potential might exist in other countries (e.g., Europe and the rest of Asia). Internalization/transaction costs refers to the fact that developing certain very large scale projects, such as an automobile intended for the World market, may entail such large costs that these must be spread over several countries.

Economics of International Trade

Exchange rates come in two forms:

“Floating”—here, currencies are set on the open market based on the supply of and demand for each currency. For example, all other things being equal, if the U.S. imports more from Japan than it exports there, there will be less demand for U.S. dollars (they are not desired for purchasing goods) and more demand for Japanese yen—thus, the price of the yen, in dollars, will increase, so you will get fewer yen for a dollar.

“Fixed”—currencies may be “pegged” to another currency (e.g., the Argentine currency is guaranteed in terms of a dollar value), to a composite of currencies (i.e., to avoid making the currency dependent entirely on the U.S. dollar, the value might be 0.25*U.S. dollar+4*Mexican peso+50*Japanese yen+0.2*German mark+0.1*British pound), or to some other valuable such as gold. Note that it is very difficult to maintain these fixed exchange rates—governments must buy or sell currency on the open market when currencies go outside the accepted ranges. Fixed exchange rates, although they produce stability and predictability, tend to get in the way of market forces—if a currency is kept artificially low, a country will tend to export too much and import too little.

Trade balances and exchange rates. When exchange rates are allowed to fluctuate, the currency of a country that tends to run a trade deficit will tend to decline over time, since there will be less demand for that currency. This reduced exchange rate will then tend to make exports more attractive in other countries, and imports less attractive at home.

Measuring country wealth. There are two ways to measure the wealth of a country. The nominal per capita gross domestic product (GDP) refers to the value of goods and services produced per person in a country if this value in local currency were to be exchanged into dollars. Suppose, for example, that the per capita GDP of Japan is 3,500,000 yen and the dollar exchanges for 100 yen, so that the per capita GDP is (3,500,000/100)=$35,000. However, that $35,000 will not buy as much in Japan—food and housing are much more expensive there. Therefore, we introduce the idea of purchase parity adjusted per capita GDP, which reflects what this money can buy in the country. This is typically
