Supply 1.5 Flashcards
Definition of Supply
Supply is the quantity of a product suppliers offer at a given price.
Higher prices incentivise suppliers to increase the quantity they offer to the market.
The Supply Curve
Typically slopes upward (left to right), indicating more is supplied at higher prices.
Movement along the supply curve: Caused by a change in price alone.
Shift in the supply curve
Caused by other factors, moving the curve left or right.
Factors Affecting Supply — Production costs
Higher production costs (wages, raw materials, rent) decrease supply.
Lower costs increase supply (rightward shift).
Example: Rising gas prices led to Tata Chemicals closing a factory due to reduced profitability.
Factors leading to a change in S— availability of resources
Shortages in land, labor, materials, or capital reduce supply.
Example: Skill shortages in the UK (e.g., engineers, nurses) constrained economic growth.
Factors leading to a change in S—New technology
Generally reduces production costs and increases supply (rightward shift).
Example: Advances in car and aerospace manufacturing helped revive the UK manufacturing sector.
Factor leading to a change in S—Indirect taxes
Taxes like VAT increase production costs, reducing supply (leftward shift).
Example: UK VAT increase in 2011 affected supply and raised consumer prices depending on demand elasticity.
Factors leading to a change in s—Subsidies
Government subsidies reduce costs and increase supply.
Example: UK subsidies for renewable energy encouraged the supply of low-carbon electricity.
Factors leading to a change in S—External Shocks
World events: Political instability can reduce supply, e.g., Middle Eastern conflicts affect oil supply.
Weather: Good weather increases crop yields; bad weather disrupts supply.
Government Policies: Interest rate changes and regulations affect supply by influencing business costs or market competition.
Related Goods’ Prices: Rising prices of alternatives may lead suppliers to switch production, reducing supply of the initial good.
