This paper presents a thorough empirical study of the performance of UDRP providers. We analyze the decisions of the complainants in deciding to send their claim to a particular provider and show that the duration of the dispute resolution services is at least as important as bias in determining the initial selection of providers. Our results show that the emphasis of theoretical and empirical work, which has been exclusively concentrated around the effects of pro-complainant bias, is, at least, incomplete. We then use the duration of these cases as the main variable to measure the general efficiency of each provider. Among our main findings, we claim that the various UDRP providers have different duration functions, implying the existence of forum shopping. Second, we demonstrate that there is bias in favor of specific countries for the different providers. Third, some panelists have completely different performance characteristics compared to the others suggesting that they are employing different methodologies to arrive at their decisions. Fourth, the performance of the providers is affected by the proofs presented by the complainants and respondents. Finally, we find that three member panels are just as efficient as single member panels. Our detailed analysis of the UDRP process has significant implications for the design of private dispute resolution regimes in general.
