Quantity Supplied:
Quantity supplied of a good or service is the amount that producers are willing and able to produce and sell at a given price and time period. It represents the supply side of the market and is influenced by various factors such as input costs, technology, government policies, and expectations about future prices.

Factors Affecting Quantity Supplied:

• Price of the good: As the price of a good increases, producers are more willing to supply more of it to the market, assuming all other factors remain constant.
• Cost of production: Higher production costs, such as labor, raw materials, and technology, can decrease the quantity supplied as producers may find it less profitable to produce more.
• Technology: Advances in technology can increase the efficiency of production, leading to an increase in the quantity supplied.
• Government policies: Regulations, taxes, and subsidies can impact the cost of production and ultimately affect the quantity supplied.
• Expectations: Producers' expectations about future prices can influence their decisions to supply more or less of a good in the current period.

Market Supply Curve:
The quantity supplied is typically represented graphically on a market supply curve, which shows the relationship between the price of a good and the quantity that producers are willing to supply. The supply curve slopes upwards from left to right, indicating that as the price of the good increases, the quantity supplied also increases.
In conclusion, quantity supplied is a crucial concept in economics that helps us understand how producers respond to changes in market conditions, prices, and external factors to meet the demand for goods and services.
