Bidding in common value fair division games: The winner's curse or even worse?
A unique indivisible commodity with an unknown common value is owned by group of individuals and should be allocated to one of them while compensating the others monetarily. We study the so-called fair division game (Güth, Ivanova-Stenzel, Königstein, and Strobel (2002, 2005)) theoretically and experimentally for the common value case and compare our results to the corresponding common value auction. Whereas symmetric risk neutral Nash equilibria are rather similar for both games, behavior differs strikingly. Implementing auctions and fair division games in the lab in a repeated setting under first- and second-price rule, we find that overall behavior is much more dispersed for the fair division games than for the auctions. Winners' profit margins and shading rates are on average slightly lower for the fair division game. Moreover, we find that behavior in the fair division game separates into extreme over- and underbidding.common value auction, winner's curse, fair division game
A duality web of linear quivers
We show that applying the Bailey lemma to elliptic hypergeometric integrals
on the root system leads to a large web of dualities for supersymmetric linear quiver theories. The superconformal index of Seiberg's
SQCD with gauge group and flavour
symmetry is equal to that of distinct linear quivers. Seiberg
duality further enlarges this web by adding new quivers. In particular, both
interacting electric and magnetic theories with arbitrary and can
be constructed by quivering an -confining theory with .Comment: v3: 10 pages, minor correction
Top-down Holographic Glueball Decay Rates
We present new results on the decay patterns of scalar and tensor glueballs
in the top-down holographic Witten-Sakai-Sugimoto model. This model, which has
only one free dimensionless parameter, gives semi-quantitative predictions for
the vector meson spectrum, their decay widths, and also a gluon condensate in
agreement with SVZ sum rules. The holographic predictions for scalar glueball
decay rates are compared with experimental data for the widely discussed gluon
candidates f0(1500) and f0(1710).Comment: 9 pages, 2 figures, 2 tables; to appear in the Proceedings of the
