Time factor- There are three supply periods based on the time factors he Momentary period, short period and the long period. In the momentary time period, the elasticity supply is zero 2. Ability to store the product- The product which can be stored for a longer periods are more able to react the price rises by releasing stocks or to price falls by building up stocks 3. Barrier to entry- Some industries restricts the entry of new firms into the market and this influences the responsiveness of supply to changes in price 4. The behavior of costs as output changes- If costs rise supply as output rises so that there are heavy costs involved in purchasing extra factors of production.
