"In economics, inflation is an increase in the money supply, causing the consumer price index (CPI) to increase."
A sustained increase in the general price level of goods and services in an economy over a period of time. Inflation is measured by changes in the Consumer Price Index (CPI) and is influenced by factors such as government policy, supply and demand, and international trade.
Definition of inflation: Inflation is a sustained increase in the overall price level of goods and services in an economy over a period of time.
Measurement of inflation: Inflation is measured typically by price indices such as the consumer price index (CPI) or the producer price index (PPI), which track changes in the prices of a basket of goods and services.
Types of inflation: There are different types of inflation such as demand-pull inflation, cost-push inflation, structural inflation and hyperinflation.
Causes of inflation: Inflation is typically caused by factors such as increases in money supply, increases in demand, decreases in supply, and changes in government policies.
Effects of inflation: The effects of inflation can be either positive or negative, depending on the severity and duration of the inflationary period.
Inflationary expectations: Inflation expectations can impact the growth rate of an economy, as investors and consumers may adjust their behavior in response to anticipated inflationary pressures.
Macroeconomic policies to control inflation: Governments and central banks can use monetary and fiscal policies to manage inflation, including controlling the money supply, adjusting interest rates, and reducing government spending.
The relationship between inflation and unemployment: The Phillips curve model shows the relationship between inflation and unemployment, and suggests that there is a trade-off between them.
International perspectives on inflation: Different countries have different experiences with inflation, and factors such as exchange rates and trade policies can impact the inflation rate in one country.
Impacts of inflation on different groups within an economy: Inflation can have a disproportionate impact on different groups within an economy, such as low-income households, pensioners and savers.
Demand-Pull Inflation: This occurs when the aggregate demand in an economy exceeds the aggregate supply, leading to an increase in the overall price level.
Cost-Push Inflation: This results from a decrease in aggregate supply caused by an increase in production costs, such as wages, raw materials, or taxes.
Stagflation: Stagflation is a combination of high inflation and high unemployment rates, which can be seen when an economy is experiencing supply-side shocks.
Hyperinflation: This is a situation where the rate of inflation reaches a very high level, typically over 50% per month. This type of inflation can be caused by factors such as government debt, money mismanagement, and political instability.
Structural Inflation: This type of inflation arises from structural problems in an economy, such as outdated infrastructure, lack of investment, and poor policies.
Wage Inflation: This occurs when wages of workers rise rapidly, leading to increased production costs and higher prices.
Built-in Inflation: Built-in inflation occurs when workers and businesses expect inflation, leading to higher prices and wages. This type of inflation is also known as the "inflationary spiral.".
Imported Inflation: Imported inflation arises from increasing international prices for goods and services, usually due to changes in exchange rates, trade policies, or other factors affecting the global economy.
Monetary Inflation: This type of inflation results from an increase in the money supply in an economy, which reduces the value of each unit of currency.
Sectoral Inflation: This type of inflation is specific to a particular sector of the economy, such as healthcare or housing. It can be caused by factors such as supply shortages, increased demand, or changes in policies or regulations.
"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."
"The consumer price index (CPI) is often used for this purpose."
"The employment cost index is also used for wages in the United States."
"Low or moderate inflation is widely attributed to fluctuations in real demand for goods and services or changes in available supplies such as during scarcities."
"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 favor 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."
"Low inflation reduces the risk that a liquidity trap prevents monetary policy from stabilizing the economy."
"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."
"Monetary authorities control inflation by carrying out open market operations and (more rarely) changing commercial bank reserve requirements."
