A Proof of Calibration Via Blackwell's Approachability Theorem

No 1182, Discussion Papers from Northwestern University, Center for Mathematical Studies in Economics and Management Science

Abstract: Over the past few years many proofs of calibration have been presented (Foster and Vohra (1991, 1997), Hart (1995), Fudenberg and Levine (1995), Hart and Mas-Colell (1996)). Does the literature really need one more? Probably not, but this algorithim for being calibrated is particularly simple and doesn't require a matrix inversion. Further the proof follows directly from Blackwell's approachability theorem. For these reasons it might be useful in the class room.
