________________________________________
Many different definitions of the balance of payments deficit or surplus have been used in the past. Each definition has different implications and purposes. Until about 1973 attention was focused on a definition of the balance of payments intended to measure a country's ability to meet its obligation to exchange its currency for other currencies or for gold at fixed exchange rates. To meet this obligation, countries could maintain a stock of official reserves, in the form of gold or foreign currencies that could be used to support their own currencies. A decline in this stock was considered an important balance of payments deficit because it threatened the ability of the country to meet its obligations. But that particular kind of deficit, by itself, was never a good indication of the country's financial position. The reason is that it ignored the likelihood that the country would be called upon to meet its obligation, and the willingness of foreign or international monetary institutions to provide support.
Interest in official reserve positions as a measure of balance of payments greatly diminished after 1973 as the major countries gave up their commitment to convert their currencies at fixed exchange rates. This reduced the need for reserves and lessened concern about changes in the size of reserves. Since 1973, discussions of "the" balance of payments deficit or surplus usually refer to what is called the current account. This account contains trade in goods and services, investment income earned abroad, and unilateral transfers. It excludes the capital account, which includes the acquisition or sale of securities or other property.
Because the current account and the capital account add up to the total account, which is necessarily balanced, a deficit in the current account is always accompanied by an equal surplus in the capital account, and vice versa. A deficit or surplus in the current account cannot be explained or evaluated without simultaneous explanation and evaluation of an equal surplus or deficit in the capital account.
A country is more likely to have a deficit in its current account the higher its price level, the higher its gross national product, the higher its interest rates, the lower its barriers to imports, and the more attractive its investment opportunities?all compared with conditions in other countries?and the higher its exchange rate. The effects of a change in one of these factors upon the current account balance cannot be predicted without considering the effect on the other causal factors. For example, if the U.S. government increases tariffs, Americans will buy fewer imports, thus reducing the current account deficit. But economic theory indicates that this reduction will occur only if one of the other factors changes to bring about a decrease in the capital account surplus. If none of these other factors changes, the reduced imports from the tariff increase will cause a decline in the demand for foreign currency (yen, deutsche marks, etc.) which in turn will raise the value of the U.S. dollar. The increase in the value of the dollar will make U.S. exports more expensive and imports cheaper, offsetting the effect of the tariff increase. The net result is that the tariff increase brings no change in the current account balance.
Contrary to the general perception, the existence of a current account deficit is not, in itself, a sign of bad economic policy or of bad economic conditions. If the United States has a current account deficit, all it means is that the United States is importing capital. And importing capital is no more unnatural or dangerous than importing coffee. The deficit is a response to conditions in the country. It may be a response to excessive inflation, to low productivity, or to inadequate saving. It may just as easily occur because investments in the United States are secure and profitable. Furthermore, the conditions to which the deficit responds may be good or bad and may be the results of good or bad policy, but if there is a problem, it is in the underlying conditions and not in the deficit per se.
During the eighties there was a great deal of concern about the shift of the U.S. current account balance from a surplus of $8 billion in 1981 to a deficit of $147 billion in 1987. This shift was accompanied by an increase of about the same amount in the U.S. deficit in goods. A common claim was that this shift in the international position was causing a loss of employment in the United States. But that was not true. In fact, between 1981 and 1987, the number of people employed rose by over 12 million, and employment as a percent of population rose from 60 percent to 62.5 percent.
Anxiety was also expressed over the other side of the accounts, the inflow of foreign capital that accompanied the current account deficit. Many people feared that the United States was becoming owned by foreigners. The inflow of foreign capital did not, however, reduce the assets owned by Americans. Instead, it added to the capital within the country. In any event the amount was small relative to the U.S. capital stock. Measurement of the net amount of foreign-owned assets in the United States (the excess of foreign assets in the United States over U.S. assets abroad) is very uncertain. At the end of 1988, however, it was surely much less than 4 percent of the U.S. capital stock and possibly even zero. Later, there was fear of what would happen when the capital inflow slowed down or stopped. But after 1987 it did slow down and the economy adjusted, just as it had adjusted to the big capital inflow earlier, by a decline in the current account and trade deficits.

Exchange rates between currencies have been highly unstable since the collapse of the Bretton Woods system of fixed exchange rates, which lasted from 1946 to 1973. Under the Bretton Woods system, exchange rates (e.g., the number of dollars it takes to buy a British pound or German mark) were fixed at levels determined by governments. Under the "floating" exchange rates we have had since 1973, exchange rates are determined by people buying and selling currencies in the foreign-exchange markets. The instability of floating rates has surprised and disappointed many economists and businessmen, who had not expected them to create so much uncertainty. The history of the pound sterling/U.S. dollar rate is instructive. From 1949 to 1966, that rate did not change at all. In 1967 the devaluation of the pound by 14 percent was regarded as a major economic policy decision. Since the end of fixed rates in 1973 and 1991, however, the pound, on average, either appreciated or depreciated by 14 percent every two years.
The instability of exchange rates in the seventies and eighties would not have surprised the founders of the Bretton Woods system, who had a deep distrust of financial markets. The previous experience with floating exchange rates (in the twenties) had been marked by massive instability. In an influential study of that experience, published in 1942, Norwegian economist Ragnar Nurkse argued that currency markets were subject to "destabilizing speculation," which created pointless and economically damaging fluctuations.
During the fifties and sixties, however, as stresses built on the system of fixed exchange rates, both economists and policymakers began to see exchange rate flexibility in a more favorable light. In a seminal paper in 1953, Milton Friedman argued that the fear of floating exchange rates was unwarranted. Unstable exchange rates in the twenties, he maintained, were caused by unstable policies, not by destabilizing speculation. Friedman went on to argue that profit-maximizing speculators would always tend to stabilize, not destabilize, the exchange rate. By the late sixties Friedman's view had become widely accepted within the economics profession and among many businessmen and bankers. Therefore, concern over the instability of floating exchange rates was replaced by an appreciation of the greater flexibility that floating rates would give to macroeconomic policy. The main advantage was that nations could pursue independent monetary policies and adjust easily to eliminate payments imbalances and offset changes in their international competitiveness. This change in attitude helped to prepare the way for the abandonment of fixed rates in 1973.
The instability of rates since 1973 has thus been a severe disappointment. Some of the changes in exchange rates can be attributed to differences in national inflation rates. But yearly changes in exchange rates have been much larger than can be explained by differences in inflation rates or in other variables such as different growth rates in various countries' money supplies.
Why are exchange rates so unstable? Economists have suggested two explanations. One, originally expressed in a celebrated 1976 paper by MIT economist Rudiger Dornbusch, is that even without destabilizing speculation exchange rates will be highly variable because of a phenomenon that Dornbusch labeled "over-shooting." Suppose that the United States increases its money supply. In the long run this must cause the value of the dollar to be lower; in the short run it will lead to a lower interest rate on dollar-denominated securities. But as Dornbusch pointed out, if the interest rate on dollar-denominated bonds falls below that on other assets, investors will be unwilling to hold them unless they expect the dollar to rise against other currencies in the future. How can the prospect of a long-run lower dollar and the need to offer investors a rising dollar be reconciled? The answer, Dornbusch asserted, is that the dollar must fall below its long-run value in the short run, so that it has room to rise. That is, if the U.S. money supply rises by 10 percent, which will eventually mean a 10 percent weaker dollar, the immediate impact will be a dollar depreciation of more than 10 percent?say 20 or 25 percent?"overshooting" the long-run value. The overshooting hypothesis helps explain why exchange rates are so much more unstable than inflation rates or money supplies.
In spite of the intellectual appeal of the overshooting hypothesis, many economists have returned to the idea that destabilizing speculation is the principal cause of exchange rate instability. If those who buy and sell foreign exchange are rational, then forward exchange rates?rates today for sale of dollars some months hence?should be the best predictors of future exchange rates. But a key study by the University of Chicago's Lars Hansen and Northwestern University's Robert Hodrick in 1980 found that forward exchange rates actually have no useful predictive power. Since that study many other researchers have reached the same conclusion.
At the same time, particular exchange rate fluctuations have seemed to depart clearly from any reasonable valuation. The run-up of the dollar in late 1984, for example, brought it to a level that priced U.S. industry out of many markets. The trade deficits that would have resulted could not have been sustained indefinitely, implying that the dollar would have to decline over time. Yet investors, by being willing to hold dollar-denominated bonds with only small interest premiums, were implicitly forecasting that the dollar would decline only slowly. Stephen Marris and I both pointed out that if the dollar were to decline as slowly as the market appeared to believe, growing U.S. interest payments to foreigners would outpace any decline in the trade deficit, implying an explosive and hence impossible growth in foreign debt. It was therefore apparent that the market was overvaluing the dollar. Overall, there is no evidence supporting Friedman's assumption that speculators would act in a rational, stabilizing fashion. And in several episodes Nurkse's fears of destabilizing speculation seem to ring true.
What are the effects of exchange rate instability? The effects on both the prices and volumes of goods and services in world trade have been surprisingly small. During the eighties real West German wages went from 20 percent above the U.S. level to 25 percent below, then back to 30 percent above. One might have expected this to lead to huge swings in prices and in market shares. Yet the effects, while there, were fairly mild. In particular, many firms seem to have followed a strategy of "pricing to market" (i.e., keeping the prices of their exports stable in terms of the importing country's currency). Significant examples are the prices of imported automobiles in the United States, which neither fell when the dollar rose nor increased much when it began to fall. Statistical studies, notably by Wharton economist Richard Marston, have documented the importance of pricing to market, especially among Japanese firms.
The policy implications of unstable exchange rates remain a subject of great dispute. Refreshingly, this is not the usual debate between laissez-faire economists who trust markets and distrust governments, and interventionist economists with the opposite instincts. Instead, both camps are divided, and advocates of both fixed and floating rates find themselves with unaccustomed allies. Laissez-faire economists are divided between those, like Milton Friedman, who want stable monetary growth and therefore want to leave the exchange rate alone, and those who, like Columbia University's Robert Mundell, want the discipline of fixed exchange rates and even a return to the gold standard. Interventionists are divided between those who, like Yale's James Tobin, regard exchange rate instability as a price worth paying for the freedom to pursue an activist monetary policy, and those who, like John Williamson of the Institute for International Economics, distrust financial markets too much to trust them with determining the exchange rate.
In general, sentiment among both economists and policymakers has drifted away from belief in freely floating rates. On the one hand, exchange rates among the major currencies have been more erratic than anyone expected. On the other hand, the European Monetary System, an experiment in quasi-fixed rates, has proved surprisingly durable. Taking the long view, however, attitudes about exchange rate instability have repeatedly shifted, proving ultimately as poorly grounded in fundamentals as the rates themselves.
