Questions & Answers

Q: What is inflation and how is it measured?

Inflation is the increase in the general price level of goods and services, typically measured by the Consumer Price Index (CPI), which tracks the weighted average of prices of a basket of goods and services.

Q: How do cost-push inflation and demand-pull inflation differ?

Cost-push inflation occurs when production costs rise, leading to price increases, while demand-pull inflation happens when demand outstrips supply, causing prices to rise due to increased consumer spending.

Q: What is deflation, and what are its consequences?

Deflation is the sustained decrease in the general price level of goods and services, leading to a situation where the same amount of money can buy more. It can trigger a deflationary spiral with negative effects on debtors and the economy.

Q: How did John Maynard Keynes view deflation during the Great Depression?

Keynes believed that the economy was not self-correcting and that intervention, such as increasing spending or reducing taxes, was necessary to counter deflation and stimulate economic recovery.
