Calculating Santa’s Workload
Philip Bump at The Atlantic attempts to answer an important question: what exactly is Santa’s Christmas Eve workload? He considered both the number of Christian children in the world and the geographic distribution of those children and reaches the following conclusion:
There are just over 526,000,000 Christian kids under the age of 14 in the world who celebrate Christmas on December 25. In other words, Santa has to deliver presents to almost 22 million kids an hour, every hour, on the night before Christmas. That’s about 365,000 kids a minute; about 6,100 a second. Totally doable.
Especially when you consider the uneven distribution of kids in the world. Santa needs to hit 22 million kids every hour. If Santa starts at the International Date Line and heads west, the first four time zones he passes barely contain that many kids waiting for presents. He’s already got three hours in the bank. Until, you know, he gets to Europe, which kind of breaks his schedule.
Bump offers a few caveats: not everyone celebrates on Dec. 25; some Christians don’t celebrate, while some non-Christians still expect a visit from Santa, etc. Overall, though, we think it’s a pretty good estimate — check out the post for detailed graphs.
Artist Resale Royalties: Do They Help or Hurt?
In America, it’s sometime said, all big trends start in California. That’s true for great things like hot tubs, the iPod, and Pinkberry. It’s also true for bad things, like tax revolts, Pinkberry, and . . . artist resale royalties.
Artist resale royalties? In a previous post, we explained how California’s law guaranteeing artists 5 percent of the profits from any later sale of their artwork has some unintended consequences. The California law helps the tiny fraction of artists fortunate enough to have their work appreciate significantly in value. But it does nothing for the 99% of artists whose work has little enduring commercial value. Not only does it not help them, it probably hurts them. Read More »
College Football Victories = Worse Grades?
Yes, at least for guys. That’s according to a new study (abstract; PDF) by University of Oregon economists Jason M. Lindo, Isaac D. Swensen, and Glen R. Waddell. Drawing on 8 years of data from nearly 30,000 Oregon students, they found that three fewer Ducks’ wins per season would increase male students’ GPA scores by roughly .02 — a relatively minor effect, truth be told, considering that three extra wins in college football is the difference between a good team and a bad one.
The authors attribute the grade drop to an increase in partying and alcohol consumption when the team wins, paired with a decrease in studying. Women also tend to drink and party more when the Ducks win, but the GPA effect wasn’t nearly as strong. So if you’re the parent of an Oregon student, you might be rooting for the Ducks to lose a little more often than they do.
“Football Freakonomics”: Tebow Timing
The following is a cross-post from NFL.com, where we’ve recently launched a Football Freakonomics Project. This segment aired before last Sunday’s Patriots-Broncos game.
One of the arguments both for and against Tim Tebow as a viable, long-term NFL starter is the idea that he should simply not be doing what he’s doing right now. Tebow’s critics say he’s getting far too much credit for his 7-1 record as a starter this season – that he’s benefiting from an unexplainable run of luck — while his supporters point to the exceptional performances he’s turned in immediately following those fortuitous bounces.
So how is a team that ranks second-to-last in passing yards, whose quarterback completes fewer than half his throws, pulling out miraculous victories week after week? Read More »
