It’s that time of year again! By which I mean, the once-in-a-lifetime opportunity to enter the eleventh annual Econbrowser NCAA tournament challenge! All right, so last year you had a chance to enter the tenth annual challenge, which was kind of similar. But whether or not you tried it last year, here’s an all new roll of the dice to see how well you can predict the outcome of this year’s U.S. college men’s basketball tournament. If you want to participate, go to the Econbrowser group at ESPN, do some minor registering to create a free ESPN account if you haven’t used that site before, and fill in your bracket before Thursday at noon!
