Key Terms Demand: The quantity of a good or service that a consumer is willing and able to buy at a reasonable price.Law of Demand: States that as price for a good or service increases, demand for it will decrease, ceteris paribus.Ceteris Paribus: Assuming no other factor changesConsumer: An individual household that demands a good or serviceConsumer Choices: Economic decision a consumer makes between alternatives as a result of scarcity.Resources: Those things that are available to us to help us achieve our needs and wants.Means: Personal resources such as time, skills and money, including those of family/community.Limited Means: Restricted personal resources such as time, timeUnlimited Wants: Endless amount of wanted goods or services that the consumer is either unable or not willing to buyScarcity: Occurs when unlimited wants exceed limited MeansNeeds: Things that we have in order to survive, such as food & water, shelter and warmth.Wants: Things that we desire but can live without.Opportunity Cost: The next best alternative forgone. What we give up (forgo) when a choice is made.Values: Ideas morals or beliefs which a person, group and/or society, consider to be important and they live by them.

Effects of Price Changes on Demand Notes: P1 & P2, Q1 & Q2 show the prices and quantity demanded before and after the change Dotted lines show each of the price and quantity demanded combinations Use arrows to show the direction of the change in price and quantity demanded A change in price results in a shift along the demand curve to a new point.

Non-Price factors affecting demand The law of demand states that, at higher prices, the amount that a consumer will purchase will decrease, ceteris paribus. If some factor other than price changes, then the amount the consumer would be willing and able to buy at each price may change; that is, the whole demand curve could shift.Notes: Arrows show directions of shifts, (left or right). New demand curve is labelled 'D' If the curve shifts to the left (i.e. less is demand at each price), then there would be a 'decrease in demand' What will cause a shift of the demand curve? Tastes and Preferences: A persons tastes change over time as new interest arise and old ones fade. Income: Changes in income affect the amount of a good or service
