Inflation: The Silent Eroder of Purchasing Power | Frenly Academy

Inflation, a sustained increase in the general price level of goods and services in an economy over time, is a complex and multifaceted phenomenon that affects the purchasing power of consumers. It is measured as an annual percentage increase in the Consumer Price Index (CPI), which tracks changes in the prices of a basket of goods and services. The causes of inflation are varied, including demand-pull factors such as economic growth and supply-chain disruptions, as well as cost-push factors like increases in wages and raw materials. Notable economists like Milton Friedman and John Maynard Keynes have offered differing perspectives on the role of monetary policy in controlling inflation. The impact of inflation can be significant, with high inflation rates eroding savings and fixed incomes, while low and stable inflation rates can foster economic growth. For instance, the inflation rate in the United States, as measured by the CPI, averaged around 2.5% from 2010 to 2020, according to data from the Bureau of Labor Statistics.
