Final Answer:
A reduction in the proportion of contracts that are indexed weakens the relationship between changes in the unemployment rate and inflation.
Step-by-step explanation:
Reducing the proportion of contracts that are indexed implies a decrease in the number of agreements tied to inflation, such as cost-of-living adjustments. This reduces the direct impact of changes in the unemployment rate on inflation.
When a significant portion of contracts is indexed, rising unemployment can trigger increased wages, contributing to inflation. However, with fewer indexed contracts, the transmission mechanism between unemployment and inflation weakens.
Indexed contracts act as an automatic stabilizer. When unemployment rises, indexed contracts lead to higher wages and, consequently, increased demand and inflation. Let's denote the proportion of indexed contracts as I and the change in the unemployment rate as ΔU. The impact on inflation (ΔI) can be expressed as ΔI = α * ΔU, where α is the sensitivity coefficient.
If I decreases, α decreases, diminishing the influence of unemployment on inflation. This reduction in automatic stabilizers weakens the correlation between changes in the unemployment rate and inflation.
Additionally, the reduced reliance on indexed contracts may lead to more discretionary wage-setting practices. Employers may be less compelled to raise wages during economic downturns, further dampening the pass-through effect from unemployment to inflation. In summary, a lower proportion of indexed contracts disrupts the traditional relationship between changes in the unemployment rate and inflation by diminishing the role of automatic stabilizers and altering wage-setting dynamics.
