Price rigidity is a characteristic of:

Question

Accepted Answer

The correct option is 3:
Price rigidity refers to a situation where the market price for a product remains stable or sticky, resisting upward or downward changes, even when costs or demand conditions change. This phenomenon is a hallmark of imperfectly competitive market structures, most notably **Oligopoly** (which falls under the broad category of Imperfectness of the Market). In an oligopoly, the actions of one firm are closely watched by rivals. The concept of the "kinked demand curve" specifically explains price rigidity: competitors are assumed to ignore price increases but match price decreases, making any price change unprofitable for the initiating firm. Therefore, prices tend to stay rigid at the current level to avoid detrimental consequences. Since oligopoly is a type of imperfect competition, price rigidity is a direct characteristic of the general imperfectness of the market.

The incorrect option is 1:
Full employment refers to a macroeconomic condition where all available labor resources are being used efficiently. While economic stability can influence pricing environment, full employment is not a market structure characteristic that causes price rigidity in microeconomics.

The incorrect option is 2:
Longrun stability is a broad term suggesting the persistence of an economic state over time. Price rigidity is a specific behavioral outcome in certain market structures (like oligopoly), not a general description of long-run market equilibrium or stability.

The incorrect option is 4:
Perfect competition is the opposite of a market characterized by price rigidity. In perfect competition, firms are "price takers," and prices are perfectly flexible, instantly adjusting to changes in supply and demand to ensure equilibrium. Price rigidity cannot exist in a perfectly competitive environment.
