Your favourite mathematical party trick has a snazzy website


Ariel Procaccia and Jonathan Goldman of Carnegie Mellon University have taken it upon themselves to make fair division problems easier to solve with a flashy new website called Spliddit (eyy, fuhgeddaboudit).

Watch Tim Harford recording a new radio show about economics for the BBC

Nobel prize for economics awarded to a mathematician

There may be no Nobel in mathematics, but that needn’t stop mathematicians winning one: Lloyd Shapley has just won the Nobel prize for economics, for the theory of stable allocations and the practice of market design. ((Though technically it’s not a Nobel prize, and actually the Sveriges Riksbank Prize in Economic Sciences in Memory of Alfred Nobel. Perhaps Alfred Nobel’s made-up wife also had an affair with a fantastical economist.))

Lloyd Shapley described himself in an Associated Press interview:

“I consider myself a mathematician and the award is for economics. I never, never in my life took a course in economics.”

But if you don’t take his word for it, look on over at his entry on the Mathematics Genealogy Project, and you’ll find his thesis is on “Additive and Non-Additive Set Functions”.

The Nobel prize website has some details on the theory of stable allocations and market design, but an old AMS feature column gives a gentler mathematical introduction, via the elegant graph theory of Hall’s Marriage theorem.

New UK economic and social data service to launch in October

The UK Data Service, due to launch on 1 October 2012, is funded for five years by the Economic and Social Research Council (ESRC) and aims to “support researchers in academia, business, third sector and all levels of government” by providing “a unified point of access to the extensive range of high quality economic and social data, including valuable census data”.

Out-of-work economists will probably not turn to bank robbery

Three economists decided to examine bank robbery as an economic activity. They were given access to data from the British Bankers’ Association on the amounts stolen during robberies, pretended to be statisticians for a bit, and came up with some interesting results. They’ve written up their findings in a feature article in the June edition of Significance.
