Understanding Inflation and Deflation: What You Need to Know

TLDRInflation is a sustained increase in the general price level, while deflation is a sustained decrease. Inflation can be caused by an increase in the cost of production or a surge in demand. Deflation, on the other hand, can lead to economic and social crises. Monetarists argue that changes in the supply or velocity of money can cause deflation. Historically, the US has experienced both inflation and deflation, with economists differing on the need for intervention to counter deflation.
