Inflation

Extracted Attributes

• Causes

  Fluctuations in real demand (demand shocks), changes in available supplies (supply shocks), changes in inflation expectations, and persistent excessive growth in the money supply.

• Definition

  A general increase in the prices of goods and services in an economy, leading to a reduction in the purchasing power of money.

• Negative Effects

  Increased opportunity cost of holding money, uncertainty over future inflation discouraging investment and savings, and potential shortages due to consumer hoarding.

• Opposite Concept

  Deflation (a decrease in the general price level).

• Primary Measurement

  Inflation rate, the annualized percentage change in a general price index, most commonly the Consumer Price Index (CPI).

• Monetary Policy Tools

  Setting of interest rates, open market operations, and (more rarely) changing commercial bank reserve requirements.

• Responsible Authority

  Central banks (e.g., Federal Reserve, Reserve Bank of Australia).

• Economists' Preferred Rate

  Low and steady (typically around 2-3% annual consumer price inflation).

• Other Measurement (US Wages)

  Employment Cost Index.

  Reduced unemployment (due to nominal wage rigidity), greater central bank freedom in monetary policy, encouragement of loans and investment, and avoidance of inefficiencies associated with deflation.

• US Historical Average Rate (since 1635)

  0.94% per year.

• US Historical Overall Price Difference (since 1635)

  3,773.07%.

Inflation

In economics, inflation is an increase in the average price of goods and services in terms of money. This increase is measured using a price index, typically a consumer price index (CPI). When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of CPI inflation is deflation, a decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. Changes in inflation are widely attributed to fluctuations in real demand for goods and services (also known as demand shocks, including changes in fiscal or monetary policy), changes in available supplies such as during energy crises (also known as supply shocks), or changes in inflation expectations, which may be self-fulfilling. Moderate inflation affects economies in both positive and negative ways. The negative effects would include an increase in the opportunity cost of holding money; uncertainty over future inflation, which may discourage investment and savings; and, if inflation were rapid enough, shortages of goods as consumers begin hoarding out of concern that prices will increase in the future. Positive effects include reducing unemployment due to nominal wage rigidity, allowing the central bank greater freedom in carrying out monetary policy, encouraging loans and investment instead of money hoarding, and avoiding the inefficiencies associated with deflation. Today, most economists favour a low and steady rate of inflation. Low (as opposed to zero or negative) inflation reduces the probability of economic recessions by enabling the labor market to adjust more quickly in a downturn and reduces the risk that a liquidity trap prevents monetary policy from stabilizing the economy while avoiding the costs associated with high inflation. The task of keeping the rate of inflation low and stable is usually given to central banks that control monetary policy, normally through the setting of interest rates and by carrying out open market operations.

• Inflation: Prices on the Rise - International Monetary Fund (IMF)

  Inflation is the rate of increase in prices over a given period of time. Inflation is typically a broad measure, such as the overall increase in prices or the increase in the cost of living in a country. But it can also be more narrowly calculated—for certain goods, such as food, or for services, such as a haircut, for example. Whatever the context, inflation represents how much more expensive the relevant set of goods and/or services has become over a certain period, most commonly a year. [...] expressed relative to a base year is the _consumer price index_(CPI), and the percentage change in the CPI over a certain period is _consumer price inflation_, the most widely used measure of inflation. (For example, if the base year CPI is 100 and the current CPI is 110, inflation is 10 percent over the period.) [...] It may be one of the most familiar words in economics. Inflation has plunged countries into long periods of instability. Central bankers often aspire to be known as “inflation hawks.” Politicians have won elections with promises to combat inflation, only to lose power after failing to do so. Inflation was even declared Public Enemy No. 1 in the United States—by President Gerald Ford in 1974. What, then, is inflation, and why is it so important?

  Inflation is the increase in the prices of goods and services over time. Inflation cannot be measured by an increase in the cost of one product or service, or even several products or services. Rather, inflation is a general increase in the overall price level of the goods and services in the economy.

• What is inflation: The causes and impact

  Inflation refers to a broad rise in the prices of goods and services across the economy over time, eroding purchasing power for both consumers and businesses. Economic theory and practice, observed for many years and across many countries, shows that long-lasting periods of inflation are caused in large part by what’s known as an easy monetary policy. In other words, when a country’s central bank sets the interest rate too low or increases money growth too rapidly, inflation goes up. As a [...] But inflation isn’t all bad. In a healthy economy, annual inflation is typically in the range of two percentage points, which is what economists consider a sign of pricing stability. When inflation is in this range, it can have positive effects: it can stimulate spending and thus spur demand and productivity when the economy is slowing down and needs a boost. But when inflation begins to surpass wage growth, it can be a warning sign of a struggling economy. [...] If inflation is one extreme of the pricing spectrum, deflation is the other. Deflation occurs when the overall level of prices in an economy declines and the purchasing power of currency increases. It can be driven by growth in productivity and the abundance of goods and services, by a decrease in demand, or by a decline in the supply of money and credit.

  Inflation is an increase in the prices of goods and services. The most well-known indicator of inflation is the Consumer Price Index (CPI), which measures the percentage change in the price of a basket of goods and services consumed by households (see Explainer: Inflation and its Measurement). The CPI is the measure of inflation used by the Reserve Bank of Australia in its inflation target, where it aims to keep annual consumer price inflation between 2 and 3 per cent (see Explainer:

  What is inflation? Inflation is a measure of how prices change over time. The U.S. Bureau of Labor Statistics (a part of the U.S. Department of Labor) selects a "basket of goods," which is a collection of many goods and services that are commonly used by consumers. Every month, the prices of these goods are measured and compared to previous prices. [...] The result of the Bureau of Labor Statistics' monthly "basket of goods" measurement is a single number known as the Consumer Price Index (CPI). This the weighted average of many changes in the price of goods and services. Inflation is quantified as a _rate_ because it is a measure of how the CPI changes over time. When you see an inflation rate, the number is based on change in CPI between two points in time.

In economics, inflation refers to a general increase in the prices of goods and services in an economy. When the general price level rises, each unit of currency buys fewer goods and services; consequently, inflation corresponds to a reduction in the purchasing power of money. The opposite of inflation is deflation, a sustained decrease in the general price level of goods and services. The common measure of inflation is the inflation rate, the annualized percentage change in a general price index. As prices do not all increase at the same rate, the consumer price index (CPI) is often used for this purpose. The employment cost index is also used for wages in the United States. Most economists agree that high levels of inflation as well as hyperinflation—which have severely disruptive effects on the real economy—are caused by persistent excessive growth in the money supply. Views on low to moderate rates of inflation are more varied. Low or moderate inflation may be attributed to fluctuations in real demand for goods and services, or changes in available supplies such as during scarcities. Moderate inflation affects economies in both positive and negative ways. The negative effects would include an increase in the opportunity cost of holding money, uncertainty over future inflation which may discourage investment and savings, and if inflation were rapid enough, shortages of goods as consumers begin hoarding out of concern that prices will increase in the future. Positive effects include reducing unemployment due to nominal wage rigidity, allowing the central bank greater freedom in carrying out monetary policy, encouraging loans and investment instead of money hoarding, and avoiding the inefficiencies associated with deflation. Today, most economists favour a low and steady rate of inflation. Low (as opposed to zero or negative) inflation reduces the severity of economic recessions by enabling the labor market to adjust more quickly in a downturn and reduces the risk that a liquidity trap prevents monetary policy from stabilizing the economy, while avoiding the costs associated with high inflation. The task of keeping the rate of inflation low and stable is usually given to monetary authorities. Generally, these monetary authorities are the central banks that control monetary policy through the setting of interest rates, by carrying out open market operations and (more rarely) changing commercial bank reserve requirements.
