What are nominal wages?

The amount of money a worker earns in current dollars, not adjusted for inflation.

What are real wages?

How does the CPI account for changes in consumption habits over time?

It does not fully account for substitution of cheaper goods when prices rise.

Why do some economists criticize the Consumer Price Index?

Due to its limitations, such as substitution bias and quality change bias.

What happens to business investment during high inflation?

It may decrease due to uncertainty about future prices.

How does deflation affect consumer spending?

It can lead to reduced spending as consumers wait for lower prices.

What is the relationship between real wages and purchasing power?

What results from a tripling of prices since the base year in CPI?

A price index of 300, indicating significant inflation.

What happens to the economy when there is persistent deflation?

The economy can become trapped in a deflationary spiral, leading to lower demand and falling prices.

How does inflation impact income distribution?

It can harm those on fixed incomes while benefiting borrowers.

What is the formula to calculate real wages?
