Perfect vs Monopolistic Competition Differences

Perfect Competition is wherein many small firms manufactures and supplies the same goods (or perfect substitute) to the end-user. Small firms mean each firm is too small to influence the market price of the product.

Key Differences Between Perfect and Monopolistic Competition

  • In the Perfect competition market, each firm sells a homogenous product (or Perfect substitute) whereas in the Monopolistic competition each firm will have slightly different product from each other.
  • Since products are slightly different from each other in the monopolistic market, non –price competition like advertising and promotion exists in the monopolistic market to inform buyers about the quality of the product.
  • Since the products are slightly different from each other in the monopolistic market, pricing power exists for a very short period until new players enter the market to exploit the pricing power.
  • In Perfect Competition, marginal revenue is equal to average revenue. Total revenue is defined as a price per unit multiplied by a number of units sold. Therefore, average revenue will be equal to the total revenue divided by the number of units sold. Marginal Revenue is defined as the change in the total revenue by selling an additional unit. In perfect competition, since all the units sold at an equal price, Average Revenue equals Marginal Revenue.

Perfect Competition Vs Monopolistic Done

  • In Monopolistic Competition, any firm can have pricing power for a very little time as any signal of supernormal profit would attract other firms to enter the market. Therefore if a firm in the Monopolistic market wants to sell more of its product, that firm will have to decrease the price and hence the Average revenue will decrease with the increase in the quantity sold. Also, as we all know that the demand curve is downward sloping from left to right, so every time the firm will have to decrease the price of the product to sell an additional product. This is a reason why Marginal Revenue is diverging wider and lower compared to the average revenue in the Monopolistic Market.
