Q: Inflation is good or bad for economy, Explain.Answer:-Inflation is, and has been, a highly debated phenomenon in economics. Even the use of the word "inflation" has different meanings in different contexts. Many economists, businessmen and politicians maintain that moderate inflation levels are needed to drive consumption, operating under the larger, overarching assumption that higher levels of spending are crucial for economic growth. The Federal Reserve typically targets an annual rate of inflation for the United States, believing that a slowly increasing price level keeps businesses profitable and prevents consumers from waiting for lower prices. There are some who believe the primary function of inflation is to prevent deflation.Others, however, argue that inflation is less important and even a net drag on the economy. Rising prices make savings harder, driving individuals to engage in riskier investment strategies to increase or even maintain their wealth. Some claim that inflation benefits some businesses or individuals at the expense of most others.Inflation is just pressure that keeps money moving through the system. To have a vibrant economy, you want money to constantly be in action rather than stagnating. Of course, too much pressure is dangerous and the same goes for inflation. At the same time, inflation is not without risks. In some sense, it's an implicit tax on assets. Since government bonds are denominated in currency, inflation is like an extra source of revenue. This could allow a government to levy an extra tax even if it would be opposed, rationally or not. This (rightly) worries some people. However, it does not mean we should not have any inflation! It's just something important to consider.And, of course, inflation run amok can completely destroy an economy and leads to a true economic theater of the absurd.Possible Benefits of InflationWhen the economy is not running at capacity, meaning there is unused labor or resources, inflation theoretically helps increase production. More dollars translates to more spending, which equates to more aggregated demand. More demand, in turn, triggers more production to meet that demand.Famous British economist John Maynard Keynes believed that some inflation was necessary to prevent the "Paradox of Thrift." If consumer prices are allowed to fall consistently because the country is becoming too productive, consumers learn to hold off their purchases to wait for a better deal. The net effect of this paradox is to reduce aggregate demand, leading to less production, layoffs and a faltering economy.Inflation also makes it easier on debtors, who repay their loans with money that is less valuable than the money they borrowed. This encourages borrowing and lending, which again increases spending on all levels. Perhaps most important to the Federal Reserve is that the U.S. government is the largest debtor in the world, and inflation helps soften the blow of its massive debt.Economists once believed in a real inverse relationship between inflation and unemployment, and that rising unemployment could be fought with increased inflation. This relationship was defined in the famous Phillips curve. The Phillips curve was largely discredited in the 1970s, however, when the U.S. experienced "stagflation," or high levels of inflation and rising unemployment at the same time; this was something thought to be impossible.
