Factors which determines the elasticity of supply are as follows:

• Number of producers- The number of producers in the market for a particular demanded good affects the elasticity of supply.
• Spare capacity- If the demand of the product increases or decreases, it will shift the demand curve accordingly and thus affecting the supply.
• Storage facilities- If the storage facilities for any product is available easily, the demand for the product is increased and thus affecting the supply.
• Capital investment- When a firm invests in capital, the price of any product will increase and thus affecting the elasticity of supply.
• Factor mobility-When a product is easily moved from the industry to the market, the supply curve is more elastic.
