Meaning of supply - The supply of a commodity means the
amount of that commodity which producers are able and willingness to offer for sale at a given prices.

Prof.Bach:- “Supply is a schedule of amounts that will be offered for sale at different prices during any time period,other factors remaining same”

Determinants of supply - Price of the good - Number of Producers - Factor prices - technology changes -Prices of other products of the producer. -Expectation of the future

Price of the product There is direct relationship between
price & quantity supplied.

Number of Producers
If more producers enter a market, the supply will increase, shifting the supply curve to the right.

Resource Prices or factor prices
The prices that a producer must pay for its resources (inputs) influence supply. Resource prices affect the cost of production. As resource prices increase, the cost of production increases.

Technological Changes
Changes in technology usually result in improved productivity. Increased productivity can reduce the cost of production. A decrease in the cost of production will increase supply.

Prices of other products of the firm If a firm produces more than one
product, a change in the price of one product can change the supply of another product.

Producer Expectations
Changes in producers' expectations about the future can cause a change in the current supply of products.

Law of Supply All other factors being equal, as the
price of a good or service increases, the quantity of goods or services offered by suppliers increases and vice versa.
![Page 11: Supply Analysis - Managerial economics](https://reader038.fdocuments.net/reader038/viewer/2022102710/546b5315b4af9f842c8b4c5e/html5/thumbnails/11.jpg)
Like the law of demand, the law of supply demonstrates the quantities that will be sold at a certain price. But unlike the law of demand, the supply relationship shows an upward slope. This means that the higher the price, the higher the quantity supplied. Producers supply more at a higher price because selling a higher quantity at a higher price increases revenue.

Limitations of the law of supply. - Expectations about the future price when the price rises and the seller
expects the future price to rise further,supply will decline as the seller will be induced to withhold the supplies so as to sell later and earn larger profits.

- Agriculture output law of supply will not apply in case of
agricultural commodities as their production can not be increased at once following price increases.
- factors other than price not remaining constant.

Elasticity of supply
It can be defined as the “degree of responsiveness of supply to a given change in price”
%Change in quantity supplied/%change in price.

Types of elasticity of supply. Perfectly Inelastic. - where a change in price causes no
change in quantity supplied. Es = 0

Perfectly elastic supply - where a small change in price leads to
big or infinite change in supply.

Unity elastic - where a given proportionate change in
price leads to proportionate change in supply.
