The new BusinessWeek rankings of business schools are out. Thousands of future MBAs will pour over the statistically-insignificant differences between similarly ranked schools to decide which will receive their quarter million dollars. Of course, we can disagree over the finer points of methodology. But first, BusinessWeek needs to show us that they are capable of [...]

UPDATE (16 October 2012): Cards for the Town Hall edition of Presidential Debate Bingo are now up. Let’s hope both candidates show up this time. Here are the bingo cards for the third quadrennial edition of Presidential Debate Bingo. If you’re holding card 5, note that “Jim, Wall Street can afford it” would get you [...]

The “student” athlete

In 2007, University of North Carolina basketball standout Tyler Hansbrough shared with Sports Illustrated how he is availing himself of UNC’s academic opportunities: There’s no reason I chose Swahili other than that I thought it would be cool. I enjoy it. Now we learn that “Swahili” is UNC-speak for “a non-existent class.” Other professors linked [...]

Bureaucrats and geometry

I needed a passport photo. Beyond my usual photographic concerns (the fact that photos of me all seem to bear an unfortunate resemblance to me), I was required to ensure my photo’s conformity with State Department standards. They photo must be two inches in each dimension, featuring a correctly-proportioned forward-facing non-tilted expressionless face. To provide [...]

Superfluous engineering

My wife regularly contends that while my abstract inapplicable research is pursued entirely for self-gratitude, her chosen field leads to practical, human-benefiting innovation. Economists, you see, are motivated by results that are “cool” but useless, while engineers (clearly not motivated by coolness) pursue practicality. A counter-example: The glass tank is a purported marvel of fluid [...]

Top Ten Things about Business I Learned in Business School

It takes the sustained effort of many people to create a positive corporate culture. It takes a few people no time at all to ruin it. When someone starts a sentence with “We benchmarked our performance against …” it means they screwed up, and are now covering their asses. Trying to build consensus where none [...]

Unreasonable expectations

Financial “analysis” like this makes my head spin: Earnings … were expected to beat expectations. [The Street] The S&P 500 fell last week … It’s not that most companies are failing to beat expectations, but that they may not be blowing them out. [The Globe and Mail] Front Barnett Associates in Chicago, an investment advisory firm [...]

Search costs, collusion, and moral banter

Think of the Children! (But only on Sundays, say area liquor stores) Connecticut is considering a law lifting the ban on Sunday liquor sales. The current prohibition is a throwback to the religious blue laws. Of course, like most legislation that comes under the banner of morality, someone is sneering and profiteering. Opposed to the [...]

All asterisks lead to contradictions

Free!* No money Down!* Satisfaction Guaranteed!* Those ubiquitous asterisks used to point to standard disclaimers about war, riots, or force majeure, but the small print at four point font now occupies tomes. There is a fine line between disclaimers, limitations, conditions, restrictions, and outright fraud. The following examples are nowhere near that line. Accident Forgiveness… [...]

Gaming the rankings

mike — Thu, 18 Jun 2009 19:04:00 +0000

Among the many issues with ranking schools, one of the most glaring is incorporating the input of those who are impacted by the result. Students reporting on MBA programs or University presidents ranking schools all put people influenced by the result in a position to influence the results. This creates quite the incentive problem. Recent [...]
