An international medium of exchange is required for international trade. From the late 1800s until World War I, most countries operated on the gold standard. Gold coins of standard specifications circulated freely between countries, making gold in effect an international currency. This system provided an automatic correction for some trade imbalances, but it had little liquidity (the money supply could not expand as rapidly as required by expanding trade), and it was vulnerable to short-term changes in the gold supply.
After the financial instability of the 1930s, the international monetary system was rebuilt following World War Ⅱ on the gold-exchange standard. The values of most national currencies were fixed in relation to the U. S. dollar; reserves were kept in dollars, which could be exchanged on demand for gold at a set price (#35 on ounce until 1968). The International Monetary Fund (IMF), a key institution set up under this system, makes international loans with capital subscribed by its members which include most noncommunist states. Voting rights are proportional to the amounts subscribed. The IMF has been able, through its loans, to stabilize fluctuating currencies and to influence the internal financial policies of recipient countries, a frequently criticized practice.
The success of the gold-exchange standard, however, depended on the superior position of the United States in world trade. In the 1960s, continual balance of payments deficits lowered U. S. gold reserves and fatally undermined the system. In 1968 a two-tiered system was adopted. Government banks maintained fixed gold prices, while non-governmental buyers traded freely. Simultaneously, non-dollar special drawing rights (SDRs) were assigned to IMF members in proportion to their contributions. But these changes did not relieve strain on the U. S. dollar. In 1971 President Richard Nixon announced that dollars would no longer automatically be exchanged for gold, and since then there has been no single international monetary standard.
As a measure of money flow, the balance of payments differs from the balance of trade primarily because of its greater

Psychologists who adopt a strong behaviorist position deny that emotion experiences are matters for scientific inquiry. In contrast, some biosocial theories hold that emotion feelings must be studied because they are the primary factors in organizing and motivating human behavior. According to these theories, most of the functions attributed to emotion expressions. Such as empathy and altruism, are dependent on the organizing and motivating properties of underlying emotion feelings. Emotion experiences have several other functions.
Several lines of research have shown that induced emotion affects perception, learning, and memory. In one study, conducted by Carroll E. Izard and his students, subjects were made happy or angry and then shown happy and angry faces and friendly and hostile interpersonal scenes in a stereoscope. Happy subjects perceived more happy faces and friendly interpersonal scenes, and angry subjects perceived more angry faces and hospital interpersonal scenes. In this case, emotion apparently altered the basic perceptual process. In another study subjects were made happy or sad and then given happy and sad information about fictional persons and later asked to give their impressions and make judgments about the fictional characters. Overall, happy subjects reported more favorable impressions and positive judgments than sad subjects did. These studies provide evidence for the common wisdom that happy people are more likely to see the world through rose-colored glasses.
An extensive series of studies indicated that positive emotion feelings enhance empathy and altruism. It was shown by the American psychologist Alice M. Isen that relatively small favors or bits or good luck (like finding money in coin telephone or getting an unexpected gift) induced positive emotion in people and that such emotion regularly increased the subjects' inclination to sympathize or provide help.
Several studies have demonstrated that positive emotion facilitates creative problem solving. One of these studies showed that positive emotion enabled subjects to name more uses for common objects. Another showed that positive emotion enhanced creative problem solving by enabling subjects to see relations among objects that would otherwise go unnoticed. A number of studies have demonstrated the beneficial effects of positive emotion on thinking, memory, and action in preschool and older children.
