Price stickiness refers to the resistance of a good’s or service’s price to change, even when the broader economic context suggests that an adjustment in price would be optimal. Often observed in both microeconomic and macroeconomic contexts, price stickiness can lead to inefficiencies in markets and impact economic equilibrium.
Causes of Price Stickiness
Price stickiness can be attributed to several factors, which are often interconnected:
Menu Costs
Menu costs refer to the expenses associated with changing prices. This can include the cost of printing new menus for a restaurant, updating price tags on goods, or reconfiguring pricing in digital systems. Due to these costs, businesses may choose to keep prices consistent and avoid frequent changes.
Informational and Cognitive Constraints
Sometimes, prices remain sticky due to informational and cognitive constraints. Businesses may not have perfect information about market conditions, or they might take time to process and react to new information. Similarly, consumers might not be immediately aware of price changes and their implications, creating a delay in price adjustments.
Contractual Obligations
Long-term contracts between buyers and sellers can contribute to price stickiness. For instance, wage agreements between employers and employees, rent agreements, or supply contracts often have set prices that cannot be altered easily, regardless of short-term economic fluctuations.
Consumer Preferences
Consumers’ reactions to price changes can also play a role. If businesses believe consumers might respond negatively to frequent price modifications, they might choose to maintain stable prices to preserve customer loyalty and sales volume.
Economic Implications
Price stickiness has several significant implications for the economy:
Misallocation of Resources
When prices do not adjust as needed, resources may not be allocated optimally. For example, if prices are sticky downward during an economic recession, surplus capacities may not be utilized, leading to inefficiencies.
Impact on Monetary Policy
Price stickiness complicates the effect of monetary policy. Central banks often rely on price adjustments to control inflation and stabilize the economy. When prices are sticky, it can delay or dampen the intended effects of monetary actions, such as interest rate changes.
Real-World Examples
Example 1: Wages in Labor Markets
Wages often exhibit stickiness due to long-term employment contracts and social expectations. During economic downturns, employers might reduce hiring or cut hours instead of lowering wages, resulting in unemployment rather than reduced wage levels.
Example 2: Housing Market Prices
Home prices can be sticky downward due to psychological factors. Homeowners may be reluctant to sell at a loss, leading to prolonged periods of housing market stagnation even when economic indicators suggest price reductions.
Historical Context
The concept of price stickiness has been a focal point in economic theories and debates. Classical and Keynesian economists have differing views on price flexibility. While classical economists emphasize that prices should adjust freely in unfettered markets, Keynesians argue that price stickiness is a natural feature of real-world markets and should be accounted for in economic modeling.
Comparison with Related Terms
Wage Rigidity
Wage rigidity specifically refers to the stickiness of wages rather than general prices. Like price stickiness, it can lead to unemployment during economic downturns.
Nominal Rigidity
Nominal rigidity encompasses both price stickiness and wage rigidity, reflecting the general resistance of nominal values (prices, wages) to change.

Summary
Price stickiness is a pervasive phenomenon in economics, reflecting the resistance of prices to change despite shifts in overall economic conditions. Understanding its causes—such as menu costs, informational constraints, contractual obligations, and consumer preferences—helps in analyzing its implications on resource allocation, monetary policy, and market efficiency. Through historical context and real-world examples, the concept’s complexity and multifaceted impact become evident.
