Downward Rigidity

Definition

Downward rigidity refers to the phenomenon where prices, wages, or other economic variables tend to be resistant to decreases or reductions, even in the face of declining demand or economic conditions. This concept is particularly relevant in the context of balancing Keynesian and neoclassical models of the economy.

5 Must Know Facts For Your Next Test

1. Downward rigidity can contribute to the persistence of high unemployment rates, as wages and prices fail to adjust downward to clear the market.
2. Keynesian models often incorporate downward rigidity to explain why economies may not automatically return to full employment equilibrium, in contrast with neoclassical assumptions of flexible prices and wages.
3. Unions, implicit contracts, and menu costs can all contribute to downward rigidity in wages and prices, as firms and workers are reluctant to accept reductions.
4. Downward rigidity can lead to the existence of a non-vertical long-run Phillips curve, where there is a trade-off between inflation and unemployment.
5. The degree of downward rigidity can vary across different sectors and markets, depending on the specific institutional and behavioral factors at play.

Review Questions

• Explain how downward rigidity relates to the Keynesian model of the economy.
  • In the Keynesian model, downward rigidity in wages and prices can prevent the economy from automatically returning to full employment equilibrium. When demand falls, rigid wages and prices prevent the necessary adjustments, leading to persistent unemployment. This contrasts with the neoclassical assumption of flexible prices and wages, which would allow the economy to self-correct. Incorporating downward rigidity is a key feature that distinguishes the Keynesian model from the neoclassical approach.
• Describe the potential causes of downward rigidity in wages and prices.
  • There are several factors that can contribute to downward rigidity in wages and prices. Unions and collective bargaining agreements may make it difficult for firms to reduce wages, even in the face of declining demand. Implicit contracts between firms and workers can also lead to wage stickiness, as firms are reluctant to break these agreements. Additionally, menu costs, or the costs associated with changing prices, can make firms hesitant to reduce prices, leading to price stickiness. These institutional and behavioral factors can all play a role in creating downward rigidity in the economy.
• Analyze the potential implications of downward rigidity for the long-run Phillips curve and the trade-off between inflation and unemployment.
  • Downward rigidity can lead to the existence of a non-vertical long-run Phillips curve, where there is a persistent trade-off between inflation and unemployment. If wages and prices are resistant to decreases, even in the face of declining demand, the economy may not automatically return to full employment equilibrium. This can result in a situation where higher inflation is associated with lower unemployment, and vice versa, rather than the vertical long-run Phillips curve predicted by the neoclassical model. The degree of downward rigidity can thus have significant implications for the nature of the inflation-unemployment relationship and the policy options available to policymakers.
