2 Definition: the marginal benefit of using each additional unit of a product during a given period of time will decline

3 The demand curve slopes downward because an individuals utility, or overall satisfaction, decreases as they obtain more of a good or service

4 On a hot day, the ice cream truck rolls through your neighborhood You will most likely receive the most satisfaction from the first ice cream bar you purchase rather than the second, third, or fourth

5 2 reasons: 1. Income effect: the change in the amount that consumers will buy because the purchasing power of their income changes

6 2. Substitution effect: change in the amount that consumers will buy because they buy substitute goods instead

7 Definition: an increase or decrease in the amount demanded because of change in price A change in quantity demanded does not shift the demand curve

8 Definition: occurs when something prompts consumers to buy different amounts at every price Change in demand is also called a shift in demand because it shifts the position of the demand curve

9 Example: high unemployment rate can cause consumers to buy different quantities of goods/services

10 1. Income: as income increases/decreases it affects a persons ability to purchase goods and services Changes in income also affect the market demand curve If most consumers incomes in a market go up, total demand will increase

15 4. Consumer expectations: future expectation can affect todays buying habits

16 5. Substitute goods: goods and services that can be used in place of each other If the price of a substitute good drops, people will buy that good and not the original item
