4 Increase in demand graphDecrease in demand graph Slide Show Presentation Information presented in linear fashion. Professor determines content, depth, and order of presentation. Allows for little flexibility. Students make few choices about direction of lecture. Difficult to switch back and forth between topics.

5 Increase in demand graphDecrease in demand graph Using Action Settings Any object can be used to link to another page in the PowerPoint presentation or an external web page. Assign Action Settings in Slide Show menu.

6 Increase in demand graphDecrease in demand graph Using Action Settings By assigning an actions to objects in a presentation, a PowerPoint presentation is transformed from a Slide Show into an interaction web page. Any object can be used to link to another page in the PowerPoint presentation or an external web page. Assign Action Settings in Slide Show menu.

8 Increase in demand graphDecrease in demand graph Hyperlink Presentation Information presented in non-linear fashion. Professor determines content. Students and professor determine depth and order. Allows for more flexibility. Students make choices about direction of lecture. Easy to switch back and forth between topics or commonly used slides.

9 Increase in demand graphDecrease in demand graph Price Price is the most important determinant of demand. A demand curve plots combinations of prices and quantity demanded. A shift in price causes a shift along the demand curve

10 Increase in demand graphDecrease in demand graph Price (continued) A change in price causes a shift along the demand curve. A shift along the demand curve is referred to as a shift in the quantity demanded. A shift in any other variable except price causes a shift in the entire demand curve. A shift in the entire demand curve is referred to as a shift in demand.

11 Increase in demand graphDecrease in demand graph Income Changes in income can increase or decrease demand. A good whose demand decreases with an increase in income is called an inferior good. A good whose demand increases with an increase in income is called a normal good.

12 Increase in demand graphDecrease in demand graph Examples of changes in income An increase in income will reduce the demand for ramen noodles or generic products. An increase in income will increase the demand for cars or clothing. An increase in income will significantly increase the demand for air travel or jewelry.

13 Increase in demand graphDecrease in demand graph Prices of other goods Changes in the prices of other goods can increase or decrease demand. A good that causes an increase in the demand for another good when its price increases is called a substitute good. A good that causes a decrease in the demand for another good when its price increases is called a complementary good.

14 Increase in demand graphDecrease in demand graph Examples of changes in other prices An increase in the price of peanut butter will reduce the demand for jelly. Peanut butter and jelly are complements. An increase in the price of Pepsi will increase the demand for Coke. Pepsi and Coke are substitutes.

15 Increase in demand graphDecrease in demand graph Number of buyers An increase in the number of potential buyers will increase the demand for the good. For example, the demand for land increases as the population increases. Similarly baseball tickets are generally more expensive in larger cities.

16 Increase in demand graphDecrease in demand graph Future Prices An increase in the expected future price of a good increases current demand. A decrease in the expected future price of a good decreases current demand. For example, when a good is temporarily put on sale, people stock up on the good.

17 Increase in demand graphDecrease in demand graph Tastes Demand curves can shift due to changes in tastes over time. For example, demand for cereal may be high in the morning but low at night. Similarly, demand for Saturday Night Fever CDs may be high in the 1970s but low in the 2000s.

18 Increase in demand graphDecrease in demand graph Quality Demand curves can shift due to changes quality. At a given price, demand for Giordanos pizza is higher than the demand for Papa Johns. Similarly, CDs cost more than cassettes because the music is of higher quality.

19 Increase in demand graphDecrease in demand graph Supply? Demand curves do not shift due to changes supply. Shifts in supply change the equilibrium price causing a shift along the demand curve. Shifts in supply cause a change in the quantity demand not a shift in the demand curve.

20 Increase in demand graphDecrease in demand graph Graph of a supply shift An decrease in supply shifts the supply curve to the left. Equilibrium price increases. Quantity demanded decreases.

21 Increase in demand graphDecrease in demand graph Increase in demand An increase in demand shifts the demand curve to the right. Equilibrium price increases. Quantity demanded increases.

22 Increase in demand graphDecrease in demand graph Decrease in demand A decrease in demand shifts the demand curve to the left. Equilibrium price falls. Quantity demanded falls.
