Which of the following best describes the economic concept of inflation?

The economic concept of inflation is best described as a general rise in prices. Inflation occurs when there is an overall increase in the price level of goods and services in an economy over a period of time. This typically indicates that the purchasing power of money is declining, which means consumers can buy fewer goods and services with the same amount of money compared to a previous time period.

Inflation is often measured by tracking changes in a price index, such as the Consumer Price Index (CPI) or the Producer Price Index (PPI). These indices capture the average price changes across a wide range of goods and services, providing a comprehensive overview of how prices change in the economy.

The other options do not accurately represent the concept of inflation: a systematic reduction in prices refers to deflation, a steady increase in wages does not encompass the overall price level, and a market-driven increase in scarce goods may relate to supply and demand dynamics but does not address the general rise in prices throughout the economy.
