Predictions
Check out these predicting tools from Ian Ayres, a professor at Yale Law School who also has a Phd in Economics. As Economists one of the things we do is try to anticipate and predict future events.

iQueue
iQueue
by Ryan Knapp
The Apple iPhone is this summer's must-have gadget, and lines began forming across the country four days early for the chance to grab one of the first available. iPhones sell for about $500, and if you hope to get one early, you may have to queue up for days just for the privilege.
Paradoxically, the type of people who are willing and able to spend $500 on the iPhone are also likely to have high-paying jobs that make it difficult to take an entire week off to wait in line. Fortunately for gainfully employed iPhone seekers, summer has brought with it a surplus of young people looking to earn a bit of extra money.
Ads are popping up all over Craigslist for so-called "professional waiters" who, for a fee, will line up to buy you an iPhone. The going wait rate is currently around $250 in New York and $200 in San Francisco. Lines are now full of people donning "iWait" shirts to show off their newfound occupation.
While the iPhone scene is replete with interesting economics, perhaps the most interesting phenomenon is the group of people who choose to bear the cold nights themselves rather than pay an iWaiter. With an ample supply of "low-skilled" workers fit for the job, many still choose to do the waiting themselves. Why would someone prefer to spend his or her own valuable time waiting in line when they could pay someone else who, by virtue of their offer, almost certainly has a lower opportunity cost?
Discussion Questions
1. What factors determine a person’s opportunity cost of waiting in line to buy an iPhone?
2. What benefits might people reap from waiting in line? (Maybe they enjoy the camaraderie? Perhaps they are "purchasing" a good story to tell at parties?)
3. All transactions involve an element of risk. Contracts, social norms, property rights, insurance, and consumer protection laws can help to mitigate transaction risks and facilitate trade, but waiting in line to buy an iPhone is a fairly informal transaction. What risks do line waiters assume? What risks do the people paying line waiters assume? Search for some iPhone line waiting listings on the Craigslist site for the San Francisco area. In what ways do iWaiters attempt to mitigate transactions risks?
4. If people are willing to pay upwards of $700 ($500 cash, $200 for a waiter) for an iPhone, why doesn't Apple raise the price?
Financial Times economics reporter Tim Harford addressed a similar question about the Xbox 360 shortage of 2005 here and here.

Opportunity Cost
Two roads diverged in a wood, and I– I took the one less traveled by, And that has made all the difference—Robert Frost
The Economist.com has a nice definition of opportunity cost:
The true cost of something is what you give up to get it. This includes not only the money spent in buying (or doing) the something, but also the economic benefits (UTILITY) that you did without because you bought (or did) that particular something and thus can no longer buy (or do) something else.
The NFL draft is a popular example where opportunity costs are important. The draft is set up where draft picks are chosen sequentially, with each team having a set time to make a decision. Teams not only consider basic things like holes in the roster and which players are remaining, but they also consider possible alternatives—like choosing another player OR considering trades from other teams. Teams make mistakes when they pick a player too early–if they could have gotten the same player in a later round–or when they do not accurately gauge the value of their high pick to another team. Teams that fail to consider opportunity cost end up with some bad choices, and fans quickly voice their disagreement to management.
