Answer:
why oligopolistic prices might change infrequently
Step-by-step explanation:
A kinked demand curve model states that participants in an oligopoly market will be hesitant to increase their price if another competitor increases their price, but will decrease their price in case another competitor decreases their price. I.e. a price increase does not generate a lot of reactions by the suppliers, but a price decrease will be matched by all the other suppliers.
