Producer Behaviour and Supply


  • Cost refers to the expenditure incurred by a producer (explicitly or implicitly) on the factor as well as non-factor inputs for a given amount of output of a commodity.
  • The amount of money, which the firm receives by the sale of its output in the market, is known as its revenue.
  • The expenses incurred by producer on the factors of production (factor inputs) for their productive services rendered is known as the cost of production (or the cost).
  • Producer’s equilibrium refers to a situation of “profit maximisation”. A producer strikes his equilibrium at that level of output where profit is maximised
  • Supply is that quantity of a commodity that a firm is able and willing to offer for sale at a given price during a given period of time. It refers to the entire schedule showing various quantities of the commodity offered for sale at different possible prices of that commodity. 
  • Elasticity of Supply (Es) It refers to the percentage change in supply for a commodity with respect to percentage change in any of the factors affecting supply for that commodity.
