Okay! Here are some animated gif files for you, if you are so inclined:
Law of Demand: http://www.reffonomics.com/demand1.html
Slope of the Demand Curve: http://apecon.us/currentwork/substitutionincome.gif
Determinants of Demand: http://www.reffonomics.com/determinatesofdemand.html
Questions to ponder:
1. Give two examples of how you have observed the Law of Demand in real life.
2. Explain why a reduction in the price of a normal good does not change the demand for that good.
3. What is the difference between the income effect and the substitution effect?
4. Substitutes, complements, or unrelated? (a) peanut butter and jelly, (b) private and public transportation, (c) Coke and Pepsi, (d) alarm clocks and automobiles, (e) golf clubs and golf balls.
I'll get some on supply up this afternoon or tomorrow morning. :)
