RT Generic T1 Meeting technologies and optimal trading mechanisms in competitive search markets A1 Lester, Benjamin A1 Visschers, Ludo A1 Wolthoff, Ronald A2 Universidad Carlos III de Madrid. Departamento de Economía, AB In a market in which sellers compete by posting mechanisms, we allow for a generalmeeting technology and show that its properties crucially affect the mechanism that sellersselect in equilibrium. In general, it is optimal for sellers to post an auction without a reserveprice but with a fee, paid by all buyers who meet with the seller. However, we define a novelcondition on meeting technologies, which we call invariance, and show that meeting fees areequal to zero if and only if this condition is satisfied. Finally, we discuss how invariance isrelated to other properties of meeting technologies identified in the literature.
