Such a general increase in prices is called inflation. Of course prices of selected goods may increase for reasons unrelated to inflation: the price of fresh lettuce may rise because unseasonably heavy rainfall in California has ruined the lettuce crop, or the price of gasoline may rise if the oil-producing countries set a higher price for oil. During inflation, however, all prices tend to rise Over the last 400 years there have been many periods of inflation. In the 16th century when the Spaniards began bringing back gold and silver from the New World, prices in Western Europe moved upward as the supply of money increased. During the 19th century prices tended to go downward as food and raw materials became cheaper. After major wars such as the Napoleonic Wars and World Wars I and ll, prices again moved upward In the 1950s and 1960s a so-called creeping inflation occurred, when the general price level in the United States and Western Europe rose by an average of 1 to 5 percent each year. In the 1970s inflation increased until it reached as much as 13 percent a year in the United States Many countries have suffered from inflation more than has the United States.
