What is the difference between inflation and a price increase by a few manufacturers?

Inflation refers to the general increase in prices across an economy over time, reflecting a decrease in the purchasing power of currency. In contrast, a price increase by a few manufacturers may be specific to certain goods or services due to factors like supply chain issues, increased production costs, or changes in demand. While inflation affects the overall price level, manufacturer-specific price increases can occur independently and may not indicate broader economic trends.
