The continuing exposure of job creation tales goes to San Diego which used a Barbara Boxer appearance hailing job creation in the area. KUSI-TV reports that they can only find one job created by stimulus dollars in the area. In fact, they expose Boxer’s dishonest representation of NIH grant money for research as “stimulus” funds.

Ch. 5 Multiple choice

Gasoline gas prices are based on oil prices. Oil prices are determined by the oil supply and oil demand. Right now, both oil supply and oil demand are almost inelastic. As gasoline gas and oil prices go up, the demand stays almost the same. As the oil supply reaches peak oil or maximum production or extraction, the demand curve becomes vertical, or inelastic. The inelasticity of the oil supply and oil demand set things up for price volatility of both oil and gasoline. The seasonal changes in gas and oil prices we've seen in the last three years is probably due to reaching peak oil. This short screencast shows an inelastic oil supply curve, as well as an inelastic oil demand curve, and what happens to prices as the oil supply or oil demand change.
