Supply and Demand (micro economics)

Find one or two news articles from the Internet that illustrate a shift in supply and/or demand. The article(s) need to illustrate at least two of the four graphs. This may require two articles. The article(s) must be recent (within the last six months), and MUST NOT be from an encyclopedia or reference website that discusses demand and supply.
DO NOT use blogs.
The best articles are about changes in the price and/or sales of a particular product. Or about the changes in the costs of production or of inputs that impact the supply curve.
You then have the opportunity to demonstrate your understanding of supply and demand shifts as you explain the changes in price and quantity experienced by the product you choose.

Summarize the article(s). (Do not quote the article(s), but explain it as if you were telling someone about it. If you do use a direct quote or paraphrase, remember that citations and references are required.) If you use more than one article, then citations are required.
Explain which graph in our collection – A, B, C, or D – illustrates the shift that you identify by describing the change in price and the change in equilibrium quantity. Remember to illustrate the shifts shown in at least two of the four graphs.
Do use paragraphs in your post. And do remain focused on what is in the article.
Provide a full URL link to the article(s) along with an APA-formatted reference to the article(s) at the bottom of your submission.
Important: This is a Microeconomic course. Do not choose an article discussing Macroeconomic issues: Inflation, unemployment, trade deficit, government budget deficit, etc.

**With oil prices reaching all-time highs, and the price of gasoline rising to the point where people are beginning to change their daily driving habits, the call for alternatives to gasoline is becoming increasingly louder.
The obvious choice is for a substitute for gasoline that burns in car engines and does not require extensive modifications or even replacement of the entire vehicle for one powered by, e.g., electricity.
Ethanol has been the focus of US government energy policy. President Bush has proposed a four-fold increase in the production and use of alternative fuels in the USA. Many believe that this will lead to significant increases in the prices of food crops, as ethanol producers increase demand for corn (Graph A: increased demand which increases market price and market quantity) and more farmers convert their crops to corn, in order to benefit from the higher prices, thereby reducing the amount of other crops that they grow (Graph D: decreased supply which increases market price and decreases market quantity).
\”Corn is the main ingredient in ethanol, the primary alternative fuel in the United States and rising demand has sent supplies to their lowest levels in 34 years according to Phil Flynn, a senior market analyst at Alaron Trading in Chicago, a commodities trading firm.\” (Hargreaves, 2007)
Rising corn prices affect the supply of any good, for which corn is an input, including beef and poultry (Graph D: decreased supply which increases market price and decreases market quantity), because as input prices rise, supply falls.
Whether we see sharp increases in the prices of corn, other food crops, and meat as a result of increasing demand for alternatives to petroleum remains to be seen. There are other alternatives, including liquid fuel from coal and cellulosic ethanol, which is made from plant matter other than food crops.
Nonetheless, markets are driven by expectations, and if commodities traders fear that fuel and food prices will rise in the future, they will bid up prices today, which could lead to a self-fulfilling prophesy.
