A new Economics.SE is now in beta, with the hope that it will enjoy a happier ending than the last Economics.SE beta.
I advertise it here because I believe that CogSci.SE users might have an interest in some of the question on the Economics.SE beta (as evidenced by CogSci.SE efforts to migrate some questions from the former dying beta). In particular you might find an interest in question gathered under the decision-theory tag.
Also, feel free to migrate questions to Economics.SE if it seems relevant.
Hoping both sites can benefit from one another and swiftly move toward graduation.
