# Demand & Supply

### Price Fluctuations of Gasoline

We are all familiar with fluctuating prices of gasoline at the pump. Why does this happen? Research the recent history of gasoline pricing in your area, and attempt to relate any fluctuations you observe to documented supply and demand factors, as outlined in our book. Be sure to cite any references used. Why do the gasoline

About the relationship between interest rates and the demand for money I have to say that it is missing a factor called confidence. Many economists have said before that if the rate declined, the demand for money will rise and the contrary would be true. However, real life even if rates declined to historically low rates, if the
