1.5 Supply Flashcards
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.
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 curve: production cost
. 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 affecting supply curve: 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 affecting supply curve: new tech
. Generally reduces production costs and increases supply (rightward shift).
. Example: Advances in car and aerospace manufacturing helped revive the UK manufacturing sector.
Factors affecting supply curve: 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 affecting supply curve: subsidies
. Government subsidies reduce costs and increase supply.
. Example: UK subsidies for renewable energy encouraged the supply of low-carbon electricity.
Factors affecting supply curve: external shocks (world events, weather, government policies, related goods prices)
. 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.
