Study Notes

  • Demand is being willing and able to buy goods at a specific price.
  • The Law of Demand states people buy more when prices fall and less when prices rise.
  • Substitution effects are demonstrated when an increase in Coca-Cola's price leads to increased demand for Pepsi.
  • Economists create market demand schedules to predict how buying habits change with price changes.
  • A demand curve graphically represents a demand schedule.
  • "Ceteris Paribus" means all factors other than price remain constant.
  • Consumer expectations shift the demand curve: anticipating a price increase for a good will cause immediate demand for it.
  • Demographics include population characteristics like age, race, gender, and occupation.
  • Advertising shifts the demand curve by creating fads and trends.
  • An increase in rent leading to decreased spending on other items indicates those goods are normal goods.
  • Switching from cheap instant noodles to fancy pasta after a raise suggests instant noodles are inferior goods.
  • Elasticity of demand measures how consumers respond to price changes.
  • Milk and medicine are examples of inelastic goods.
  • Cow's milk is considered inelastic as it's a necessity without substitutes.
  • Elasticity affects pricing by showing that for elastic goods, a price increase reduces total revenue.
  • If a firm knows that the demand for its product is elastic at the current price, it knows that an increase in price would decrease total revenue
  • The law of supply states as prices increase, the quantity supplied will increase.
  • A paper plate factory producing more plates when prices increase demonstrates the law of supply.
  • If the price of home computers rises, the computer makers will make more computers
  • A supply schedule shows how much a supplier offers at different prices.
  • Supply is upward sloping while demand is downward sloping.
  • If Ruth's bread supply is highly elastic, when the price of bread falls, cut costs by hiring fewer workers
  • Fixed costs do not change like rent.
  • Variable costs rise or fall depending on the quantity produced.
  • Marginal cost is the added cost of producing one more unit.
  • Profit is calculated as total revenue minus total cost.
  • A factory losing money will continue to operate if total revenue is still greater than its total cost.
  • Increased resource costs decrease supply because the good becomes more expensive to produce.
  • Advances in technology lower production costs and increase supply.
  • A subsidy is a government payment that subsidies farmers to keep food supply up
  • When the government causes the supply of a good to rise, the supply curve shifts to the right
  • High global demand for fuel impacts changes in supply.
  • Equilibrium is the point where demand equals supply; the market is stable.
  • Both buyers and sellers benefit when a market is at equilibrium.
  • Draw an equilibrium that shows the supply and demand for an item, equilibrium price and quantity
  • Show increase or decrease in demand or supply
  • Demand is the desire to own something and the ability to pay for it
  • Substitution Effect: Consuming Less of a good and more of another as a reaction to a price increase
  • A market demand schedule is a table listing the quantity of a good that all consumers will buy at various prices
  • Substitutes are goods used in place of each other (e.g., Coke/Pepsi).
  • Complements are two goods bought and used together, like PlayStations and PlayStation Games.
  • Normal goods are goods for which demand falls as income increases
  • Inferior goods are goods for which demand falls as income increases
  • Demographics are the characteristics of populations, such as age, race, gender and occupation
  • Substitutes are goods that are used in place of each other (coke/pepsi)
  • Compliments are two goods that are bought and used together (Playstation and Playstation Games)
  • Elastic is very sensitive to price changes
  • Inelastic When demand does not change much after a price change (milk/medicine)
  • Unitary Elastic if ED = 1
  • A company's total Revenue is the amount of money the company receives from selling its goods
  • Law of Supply States that as prices increase, so will the quantity supplied
  • Supply Schedule is a chart that tells how much a supplier will offer at different prices
  • Fixed cost costs that do not change
  • Variable costs Rise or fall depend on the quantity produces
  • Regulation Law that tells how a good must be made
  • Non price factors cause demand to fall, the demand curve shifts to the left but an increase in demand appears as a shift to the right.
