Stickiness refers to the resistance of certain economic variables, particularly prices and wages, to change despite alterations in supply and demand. This phenomenon is observed when wages or prices do not adjust promptly or sufficiently in response to economic conditions.
Historical Context
The concept of stickiness gained prominence during economic discussions in the 20th century. John Maynard Keynes highlighted wage stickiness in his seminal work, “The General Theory of Employment, Interest, and Money,” which influenced the development of macroeconomic policies addressing unemployment and inflation.
Types and Categories
Wage Stickiness: Resistance to changes in wage levels, often downward, even when economic conditions warrant reductions.
Price Stickiness: The phenomenon where prices of goods and services do not adjust easily or quickly in response to market demand and supply.
Key Events and Detailed Explanations
Historical Examples
- Great Depression: Despite high unemployment, wages did not decrease substantially, contributing to prolonged economic hardship.
- 2008 Financial Crisis: Firms hesitated to cut wages significantly despite economic downturns, causing protracted unemployment.
Factors Contributing to Stickiness
- Long-Term Contracts: Employment contracts often have fixed wages over a period, making adjustments difficult.
- Menu Costs: The costs associated with changing prices, such as reprinting menus in restaurants or updating price tags, deter frequent changes.
- Psychological Factors: Employees may react negatively to wage cuts, affecting morale and productivity.
Mathematical Models
The stickiness can be illustrated through models such as:
-
Phillips Curve:
$$ \pi_t = \pi_{t-1} - \beta(u_t - u^*) $$Where:- \( \pi_t \) is the inflation rate.
- \( u_t \) is the unemployment rate.
- \( u^* \) is the natural rate of unemployment.
- \( \beta \) represents responsiveness.
-
New Keynesian Models: Incorporate sticky prices and wages into the aggregate supply curve, reflecting real-world conditions.

Importance and Applicability
Understanding stickiness is crucial for policymakers to design effective economic interventions. It informs decisions related to unemployment, inflation control, and monetary policies.
Examples and Considerations
Example: During economic slowdowns, firms may prefer layoffs over wage cuts to avoid demoralizing the workforce, showcasing wage stickiness.
Considerations: Policies need to account for stickiness to avoid unintended consequences such as prolonged unemployment or inflation.
Related Terms
- Menu Costs: Expenses incurred in changing prices.
- Ratchet Effect: A situation where variables only move in one direction and resist reverting.
Comparisons
- Flexible Prices: In contrast to sticky prices, flexible prices adjust quickly to changes in supply and demand.
- Sticky Wages vs. Sticky Prices: While both exhibit resistance to change, sticky wages are often due to psychological and contractual reasons, whereas sticky prices can be due to logistical and cost-related factors.
Interesting Facts
- Stickiness can vary by industry, with some sectors showing more resistance to price changes than others.
- Psychological studies suggest that employees perceive wage cuts more negatively than layoffs, influencing managerial decisions.
Inspirational Stories
Post-WWII Economic Policies: The successful reintegration of soldiers into the workforce without drastic wage reductions is a testament to understanding and managing economic stickiness.
