Price elasticity of supply is the responsiveness of quantity supplied of a good to a change in price. The formula for calculating PeS is PERCENTAGE CHANGE IN QD/PERCENTAGE CHANGE IN P. There are 5 TYPES of PeS graph which is elastic, inelastic, unitary, perfectly elastic and perfectly inelastic. We all know that the supply line is a line where price is proportional to the quantity supplied. For PeS elastic, the supply line cuts the Y-axis. It's known where the change in price is more than proportionate to the change in quantity demanded. Where as the PeS inelastic, the supply line cuts the X-axis. Therefor, the line shows that the change in price is less than proportionate to the change in quantity demanded. Besides that, Unitary supply line happens when the change in price is directly proportionate to the change in quantity demanded. Perfectly elastic line happens when the producer only supply their goods at a particular price, a slight change in price will give a zero value for quantity demanded. Lastly, perfectly inelastic happens when producer decided to fix its quantity supply at whatever prices they set. 

The determinants of PeS Time, length in production process, availability of surplus capacity, the ease of entering into a market. PeS is also known as the ability of a producer to adjust their production.

TIME:

A company can only produce 400 teddy bears a day, but as time passes, the company's efficiency on production went higher due to more or better machines available. Besides that, some teddy bears are hand made. The skills and creativity of the labours may increase as well. This factor will also increase the production on teddy bears in the long run.

LENGTH IN PRODUCTION PROCESS:

Manufacturing goods is categorized under secondary production. We'll know that many of our goods is made from China and it shows that the country is under secondary production Manufacturing goods are known to have an Elastic value for PeS. This is because they can expand their production easily due to the advancement of technology. Besides that, they have a long shelf life( it's non-perishable), the goods that're in surplus will be stored and when there is a high demand, the producers can easily sell these goods in the market. They get to save and earn at the same time. Capital(machines) is one of the factor that could increase the production easily on manufacturing goods. As time passes, the advancement of technology gets better and goods can be produce easily. 3D printing is also available in the market, manufactures can produce hard objects from a 2D image using plastics and other materials. In a matter of minutes, you can produce thousands of it as technology is getting better.

Agriculture goods is categorized under primary production. It's known to have an inelastic value for PeS. This is because, agriculture goods take weeks to be produced. It has a long gestation period due to climate change, as well as pesticides. Sometimes, the weather might be too hot which slows down the production on crops. Labours are widely used in primary production. We all know that many of them a cheap labours and they their income is low. What is they decided to stop working as a farmer and proceed their job to service sectors in order to earn more income. The production will be low again unless technology gets better to overcome this problem. Besides that, Agriculture goods are perishable. Producers can't produce too much of it as it'll get spoil and wasted if it's not consumed. Excess agriculture goods can't be stored too long as well. Sometimes we can change it's variable by drying up the food or putting it in the fridge so that it'll last longer

EXISTENCE OF SURPLUS CAPACITY: 

Some firms can increase their production due to spare machines.

EASE OF ENTRY IN MARKETS:

The smaller the barriers to enter a market, the higher it's ability of a firm to expand it's business and increase it's productivity.
