What is meant by purchasing power?
The ability of money to buy goods and services; it decreases when inflation occurs.
What is deflation?
A decrease in the general price level over a period of time.
What is disinflation?
A decrease in the rate of inflation, where prices are still rising but at a slower rate.
What is the base year in the context of CPI?
The year against which current prices are compared, assigned a value of 100.
How is the CPI calculated?
By comparing the current cost of a basket of goods and services to the cost in the base year.
What formula is used to calculate the inflation rate?
Inflation Rate = [(CPI in current year - CPI in previous year) / CPI in previous year] x 100.
What are nominal wages?
The amount of money a worker earns in current dollars, not adjusted for inflation.
What are real wages?
Wages adjusted for inflation, reflecting the purchasing power of income.
What is substitution bias in the context of CPI?
The assumption that consumers buy the same quantities of goods even if prices change, which can overstate inflation.
What is quality change bias?
The assumption that price increases are solely due to inflation rather than improvements in product quality.
What is a significant problem caused by unexpected inflation?
It can redistribute income, harming those with fixed incomes like retirees.
What are menu costs?
The costs businesses incur from changing prices, such as updating price tags and advertising.
How does high inflation create uncertainty for businesses?
It makes future purchasing power unpredictable, reducing willingness to invest.
What effect does deflation have on the real value of debt?
It increases the real value of debt, making it harder for borrowers to repay.
What can happen when consumers expect prices to keep falling during deflation?
They may delay purchases, reducing overall demand and leading to economic recession.
What is economic stagnation?
A situation where persistent deflation leads to reduced investment and job losses.
What is the goal of price stability in economics?
To maintain relatively slow changing prices to avoid both inflation and deflation.
What inflation rate do many economists support as a target?
A target inflation rate of 2 percent.
Why is it important to understand price indices?
They are essential for measuring inflation and understanding its impact on the economy.
What are the implications of inflation for purchasing power?
Inflation decreases purchasing power, meaning consumers can buy fewer goods for the same amount of money.
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?
Real wages reflect the actual purchasing power of income adjusted for inflation.
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?
Real Wage = Nominal Wage / (CPI / 100).
