Re-matching, Information and Sequencing Effects in Posted Offer Markets

Abstract

This paper evaluates the effects of some standard procedural variations on outcomes in posted offer oligopoly experiments. Variations studied include the presence or absence of market information, the use of re-matching or fixed seller pairs and alterations in the order of sequencing. Experimental results indicate that such variations can have first order effects on outcomes. For this reason, we recommend that results in oligopoly experiments be carefully interpreted in light of the procedures selected.Market Experiments, Oligopoly, Re-Matching, Information, Market Concentration
