Open Economy


In today’s world, most modern economies are open. Interaction with other economies of the world widens choice in three broad ways –

  1. Consumers and firms have the opportunity to choose between domestic and foreign goods. This is the product market linkage which occurs through international trade.
  2. Investors have the opportunity to choose between domestic and foreign assets. This constitutes the financial market linkage.
  3. Firms can choose where to locate production and workers to choose where to work. This is the factor market linkage.
    • Labour market linkages have been relatively less due to various restrictions on the movement of people through immigration laws.
    • Movement of goods has traditionally been seen as a substitute for the movement of labour.

An open economy is one that trades with other nations in goods and services and, most often, also in financial assets. Indians, for instance, enjoy using products produced around the world and some of our production is exported to foreign countries. Foreign trade, therefore, influences Indian aggregate demand in two ways –

  • First, when Indians buy foreign goods, this spending escapes as a leakage from the circular flow of income decreasing aggregate demand.
  • Second, our exports to foreigners enter as an injection into the circular flow, increasing aggregate demand for domestically produced goods.
  • Total foreign trade (exports + imports) as a proportion of GDP is a common measure of the degree of openness of an economy.

In 2004-2005, this was 38.9 per cent for the Indian economy (imports constituted 17.1 per cent and exports 11.8 per cent of GDP). This is substantially higher than a total of 16 per cent that prevailed in 1985-86. However, in comparison to other countries, India is relatively less open. There are several countries whose foreign trade proportions are above 50 per cent of GDP.

Now, when goods move across national borders, money must move in the opposite direction.

At the international level, there is no single currency that is issued by a central authority. Foreign economic agents will accept a national currency only if they are convinced that the currency will maintain a stable purchasing power. Without this confidence, a currency will not be used as an international medium of exchange and unit of account since there is no international authority with the power to force the use of a particular currency in international transactions.

Governments have tried to gain confidence of potential users by announcing that the national currency will be freely convertible at a fixed price into another asset, over whose value the issuing authority has no control. This other asset most often has been gold, or other national currencies. There are two aspects of this commitment that has affected its credibility –

  • the ability to convert freely in unlimited amounts and
  • the price at which conversion takes place.

The international monetary system has been set up to handle these issues and ensure stability in international transactions.

A nation’s commitment regarding the above two issues will affect its trade and financial interactions with the rest of the world.
