Question 1

What is Price Elasticity of Supply in the context of Edexcel International A Levels Economics?

Accepted Answer

Price Elasticity of Supply (PES) measures how much the quantity supplied of a good responds to a change in its price. In the context of Edexcel International A Levels Economics, understanding PES helps students analyze how suppliers react to price changes in the 'Markets in Action' module.

Question 2

How is Price Elasticity of Supply calculated?

Accepted Answer

Price Elasticity of Supply is calculated using the formula: PES = (% change in quantity supplied) / (% change in price). This calculation helps determine whether the supply of a good is elastic (responsive) or inelastic (unresponsive) to price changes.

Question 3

What factors affect the Price Elasticity of Supply?

Accepted Answer

Several factors influence PES, including the availability of resources, production time, and the ability to store stock. For instance, goods that require a long time to produce or have limited resources tend to have inelastic supply, while those that can be produced quickly and stored easily have more elastic supply.

Question 4

Why is understanding Price Elasticity of Supply important in Economics?

Accepted Answer

Understanding PES is crucial because it helps predict how changes in market prices will affect supply levels. This knowledge is vital for businesses and policymakers in making informed decisions about production, pricing strategies, and market regulations, which are key components of the 'Markets in Action' module in Edexcel International A Levels.

Question 5

Can you provide an example of Price Elasticity of Supply?

Accepted Answer

An example of PES can be seen in agricultural products. If the price of wheat increases, farmers may not be able to quickly increase supply due to the time needed for planting and harvesting, indicating inelastic supply. Conversely, a manufacturer of digital goods can quickly ramp up production if prices rise, demonstrating elastic supply.
