Questions this Inflation and deflation deck will help you answer

Definition Flip

Define inflation and disinflation. What is the key difference between the two?

Answer Flip

Inflation is a sustained increase in the general price level in an economy. Disinflation is a decrease in the *rate* of inflation, meaning prices are still rising, but at a slower pace. Inflation means prices are rising faster.

Key Concept Flip

Explain the concept of deflation, including its potential economic consequences.

Answer Flip

Deflation is a sustained decrease in the general price level. It can lead to decreased consumer spending as consumers delay purchases expecting further price drops, leading to decreased production and economic stagnation. This is known as a deflationary spiral.

Definition Flip

What is hyperinflation, and what are its likely effects on an economy?

Answer Flip

Hyperinflation is extremely rapid or out-of-control inflation. It erodes purchasing power quickly, destabilizes the economy, encourages spending rather than saving, and can lead to a breakdown in the monetary system. An example is Zimbabwe in the late 2000s.

Definition Flip

Describe the Consumer Price Index (CPI) and its purpose in measuring inflation.

Answer Flip

The CPI is a measure of the average change over time in the prices paid by urban consumers for a basket of consumer goods and services. It is used to track inflation, adjust wages and pensions, and assess the impact of price changes on living standards.

Key Concept Flip

Explain cost-push inflation, giving a specific example of a cause.

Answer Flip

Cost-push inflation occurs when there is an increase in the costs of production for firms, which they pass on to consumers through higher prices. An example is a sharp rise in oil prices, which increases transportation and production costs.

Key Concept Flip

Explain demand-pull inflation, giving a real-world example.

Answer Flip

Demand-pull inflation occurs when there is an increase in aggregate demand that outpaces the economy's ability to produce goods and services. This leads to a general rise in prices.

Example: large government spending in a growing economy.
Key Concept Flip

Discuss two potential negative consequences of high inflation on an economy.

Answer Flip

High inflation erodes purchasing power, making it more difficult for people to afford goods and services. It also creates uncertainty for businesses, discouraging investment and long-term planning, and reduces international competitiveness.

Key Concept Flip

Discuss two potential negative consequences of deflation on an economy.

Answer Flip

Deflation can lead to delayed spending as consumers expect prices to fall further, leading to a decrease in aggregate demand and economic activity. It also increases the real burden of debt, making it more difficult for individuals and businesses to repay loans.

Key Concept Flip

How might a central bank use interest rates to combat inflation?

Answer Flip

A central bank can raise interest rates to combat inflation. This makes borrowing more expensive, which reduces consumer spending and investment, thereby decreasing aggregate demand and putting downward pressure on prices.

Key Concept Flip

Explain how an increase in wages can contribute to inflation.

Answer Flip

An increase in wages can lead to cost-push inflation if businesses increase prices to cover these higher labor costs. It can also lead to demand-pull inflation if higher wages increase consumer spending, driving up demand for goods and services.
