Which of the following is a major criticism of the kinked demand curve model of oligopoly?

The main criticism is that the model explains why prices stay rigid once set but not how the prevailing price was determined in the first place. It is therefore an incomplete theory of price determination in oligopoly.

  1. AIt assumes that there is only one seller in the market
  2. BIt assumes free entry and exit of firms with identical products
  3. CIt explains price rigidity but does not explain how the original price was determinedCorrect
  4. DIt predicts that firms always cut prices to gain market share

Explanation

The model starts from an existing price and shows why it tends to stay unchanged, but it does not explain how that price was arrived at. The other options misdescribe oligopoly: it has few sellers, barriers to entry and the model predicts rigidity rather than frequent price cuts.
