Kinked Demand Curve and Price Rigidity in Oligopoly Quiz

In the kinked demand curve model, firms in an oligopoly face a demand curve that is more elastic above the current price and less elastic below it. This kink occurs because competitors are expected to match price decreases but not price increases, leading to different demand elasticity depending on price movements, which stabilizes prices in the market.

In an oligopoly, firms are interdependent. If one firm raises prices, competitors may not follow, leading to a loss of customers for the firm that increased prices. Conversely, if one firm lowers prices, others typically match to maintain their market share, preventing a significant loss of customers. This behavior helps stabilize the market.

The kinked demand curve illustrates that firms face different elasticities of demand above and below a certain price. This results in a marginal revenue curve that has a discontinuity, as firms do not change prices easily in response to competitors, leading to a sudden drop in marginal revenue at the kink point.

Price rigidity in oligopoly arises from the interdependence of firms within the market. When one firm alters its prices, others may respond with similar changes to maintain competitiveness, leading to a price war. This fear of retaliation discourages firms from changing prices, resulting in stability despite changes in demand or costs.

In the kinked demand curve model, the upper segment is more elastic because a price increase leads to a significant drop in quantity demanded, as consumers can easily switch to substitutes. Conversely, the lower segment is less elastic, as price decreases result in a smaller increase in quantity demanded, indicating that consumers are less responsive to price changes.

In oligopolistic markets, firms face a kinked demand curve, where a price increase leads to a significant loss of market share, while a price decrease does not significantly increase sales due to competitors not following suit. This creates a reluctance to change prices, as firms fear competitive retaliation and potential losses.

In the kinked demand curve model, if a firm raises its price, competitors typically do not follow suit. As a result, the firm loses customers who are sensitive to price changes, leading to a decrease in total revenue. This reflects the model's assumption that demand is more elastic above the kink, making price increases detrimental to revenue.

The kinked demand curve model suggests that firms operate under the assumption that their competitors will react predictably to price changes. Specifically, if one firm lowers its prices, others will follow to maintain market share, while if a firm raises prices, competitors will not match the increase, leading to a loss of customers.

Under the kinked demand curve model, oligopolists may break through established price levels due to significant changes in market conditions. A decrease in production costs, an increase in demand, or shifts in consumer preferences can compel firms to adjust prices to maintain competitiveness, thus leading to a potential price change across the industry.

Price leadership is a common phenomenon in oligopolistic markets where one firm sets prices that others follow, allowing for stable pricing without aggressive competition. This model contrasts with the kinked demand curve, which suggests firms react differently to price changes. Price leadership provides a simpler explanation for how firms coordinate pricing strategies.

Under the kinked demand curve model, firms face a situation where they are reluctant to change prices in response to cost increases. This is because raising prices may lead to a loss of market share, while lowering prices could trigger a price war. Thus, the marginal revenue curve shows a discontinuity, leading to stable prices despite cost changes.

The kinked demand curve model posits that firms in an oligopoly face a demand curve that is more elastic above the current price and less elastic below it. This results in price rigidity; if marginal costs change within a certain range, firms will not alter their prices, as they anticipate competitors will not follow suit, maintaining their profit-maximizing price.
