Supply and demand at work in CA

Do Futures Contracts Protect Against Price Volatility?

The Wall Street Journal published a article showing that futures contracts are imperfect protection against price volatility because the side with the bad price will often attempt to change the contract, find grounds to declare the contract void, or simply walk away from the contract. The article discusses what happened as the price of cotton increased and then collapsed between 2012 and 2012. The history points out that the cost of enforcing a contract is often a significant transactions cost.

Time to Flip?

L. RAFAEL REIF, the new President of MIT,  has an excellent editorial on how colleges can use online teaching for residential students. Here are some highlight quotations.

• "Higher education is at a crossroads not seen since the introduction of the printing press." 
• "The network of students that came together around it was so powerful that the course's instructor stopped his teaching assistants from answering questions in the online forum. The students had said they learned the material better when they helped each other out."
• "How can online education improve the residential experience? At MIT, we got a hint when we allowed a test set of MIT students to take the MITx version of Circuits and Electronics, supplemented by weekly contact with faculty, for credit. They liked the experience and demonstrated deep comprehension of the material.
  
  Some are calling this model the "flipped classroom."

Does this reporter make sense?

I suspect that the reporter has confused cause with effect in a curious account of the gasoline market in California. The first sentence states that retailers have stopped selling gasoline because of high prices. I have never heard of sellers not wanting to sell because the price is too high. I suspect the reduction in retailers offering gasoline for sale and high price of gasoline are both caused by a shortage of gasoline.

A second curiosity is the statement that "high costs meant profit margins were too low to stay open". Why don't the retailers simply raise price to cover the high costs? I am not aware of any price ceilings.
