Study Notes
Supply Theory
- Supply represents the amount of a product producers are willing and able to offer at different price points.
- The supply function showcases the relationship between quantity supplied and factors influencing it, often expressed as ( Q_s = a + bP ).
- The supply schedule and curve display the positive correlation between price and quantity supplied graphically and numerically.
- The supply curve's slope reflects the direct positive relationship between price and quantity supplied.
- A change in quantity supplied is a movement along the supply curve in response to price changes.
- A shift in supply is a change in the entire supply curve, triggered by factors outside price (e.g., production costs, technology, policies).
Factors Affecting Supply
- Production costs impact supply.
- Technological advancements influence supply.
- External factors (natural disasters) impact supply.
- Government policies (taxes or subsidies) affect supply.
- Transportation infrastructure impacts supply.
- Prices of related goods impact supply.
Market Supply Curve
- The market supply curve is the horizontal summation of all individual supply curves.
- A market with 120 identical sellers, each with a supply function of ( Q_s = 20P - 5 ), will have a market supply equation of ( Q_m = 2400P - 600 ).
Market Equilibrium
- Market equilibrium occurs when quantity demanded equals quantity supplied, determining equilibrium price and quantity.
- Disequilibrium happens when quantity demanded differs from quantity supplied, leading to surpluses (excess supply) or shortages (excess demand), resulting in price adjustments towards equilibrium.
- Shifts in demand or supply curves alter the equilibrium price and quantity.
- Increased demand raises both equilibrium price and quantity.
- Increased supply lowers equilibrium price but raises equilibrium quantity.
