Supreme Confusion
The econometrics teacher wrote this on the board:
A student raised his hand, and asked, "What is sup?"
The teacher angrily replied, "I'm trying to teach you the finer points of asymptotics, that's what's up."

Corporate Finance is Scary
From yesterday's post, we know corporate finance has shark repellent, porcupine provisions, poison pills, and greenmail. Could it get any worse? Now, you need to be on the lookout for golden parachutes and macaroni defenses.
I sure hope the golden parachutes don't fall out of the sky. That would hurt. (That's what the shareholder said!)
What the heck is greenmail? If you thought anthrax in the mail was scary, watch out for moldy mail! #freepenicillin
Now I want pasta! I initially suspected a macaroni defense was named for a pasta company's creative anti-takeover measure. The real reason: a macaroni defense triggers a jump in the redemption price of bonds in the event of a takeover--the prices expand like macaroni in a pot.

Toxic Takeovers
Thinking of a tender offer? Watch out for poison pills and keep this number handy.
Don't forget to be wary of shark repellent, porcupine provisions, and greenmail.
April Apologies
My apologies for not having updated the site lately. The past few weeks have been excessively busy for me. I will continue to update the site, though at lower frequency. I do have a lot of great ideas in the pipeline, so please stay tuned.
Stand Up Economist: Yoram Bauman
I had the pleasure of seeing Yoram Bauman perform at Emory University last week. If you've not seen his site, check it out: http://www.standupeconomist.com/.
Here is a direct link to a funny video: http://www.standupeconomist.com/videos-public/.
I picked up a copy of his Cartoon Introduction to Microeconomics, and I must say, it's quite entertaining.

March Madness
Regarding the NCAA basketball tournament, there has been a lot of talk about poor officiating and missed calls. People are calling the referees blind.
No wonder poor papers sometimes get published in top academic journals--they use double-blind referees.

A prerequisite for understanding derivatives is understanding derivatives.
It's good that students often have the option to take derivatives classes.

Datastream
Thompson Reuters' Datastream product is one of the most comprehensive and most commonly used sources of international data. Many researchers, however, complain about its slow speed and cumbersome interface.
Thompson Reuters should come up with an improved version, and that product should be called Datariver.

Law and Finance // Think Boolean!
Law and Finance is a subfield of finance.
Given the history of legal violations in finance, "Law or Finance" may be a more appropriate field.

No jokes here, just statistics.
I'm amazed at the response I have received since starting this blog. Thank you so much for visiting and for sharing with your friends. The pageview count recently eclipsed 1500, and people from all over the world have contributed to this. Here is a map of where the pageviews originated.
Perspectives on Dummy Variables
Stan Coleman, Trainer, Variable Special Forces:
"The life of a dummy variable is quite hard. These variables need to maintain strict focus their entire lives--they can only take values of zero or one. Can you imagine a continuous random variable doing that? They can't! It's impossible--probability zero."
Susan Gustafson, Primary School Teacher:
"I just don't understand the hype about the dummy variables. I've had many dummy variables come through my classroom. While I didn't know at the time they would grow up to become dummy variables, I distinctly remember many of these students. They were not at all interested in broadening their horizons. Forget trying to teach anything other than the Natural numbers to those students."

The Most Popular Statistic
While the mean is the least popular statistic, the mode is the most popular statistic. No wonder statistics is confusing.
