Equilibrium strategy and population-size effects in lowest unique bid auctions
In lowest unique bid auctions, players bid for an item. The winner is
whoever places the \emph{lowest} bid, provided that it is also unique. We use a
grand canonical approach to derive an analytical expression for the equilibrium
distribution of strategies. We then study the properties of the solution as a
function of the mean number of players, and compare them with a large dataset
of internet auctions. The theory agrees with the data with striking accuracy
for small population size , while for larger a qualitatively different
distribution is observed. We interpret this result as the emergence of two
different regimes, one in which adaptation is feasible and one in which it is
not. Our results question the actual possibility of a large population to adapt
and find the optimal strategy when participating in a collective game.Comment: 6 pag. - 7 figs - added Supplementary Material. Changed affiliations.
