Introduction
The term “Quantity Supplied” refers to the quantity of a good or service that producers are willing and able to sell at a specific price during a given time period. It is a key concept in the study of supply within the field of economics and plays a crucial role in determining the supply curve, which illustrates the relationship between price and quantity supplied.
Historical Context
The concept of quantity supplied has its roots in classical economics, particularly in the work of Adam Smith and later economists such as David Ricardo and Alfred Marshall. The formalization of the supply curve as a graphical representation of the relationship between price and quantity supplied came in the late 19th and early 20th centuries.

- Market Supply: The aggregate supply of a good or service from all producers in the market.
Key Events
- Industrial Revolution: Marked a significant increase in the capacity of goods supplied due to advancements in technology and production methods.
