This chapter describes repertoire-based methods for detecting and quantifying the social transmission of behavior based on a “snapshot” of the behavioral repertoires of individuals or groups. Repertoire-based methods often take the form of a group contrast approach, where the researcher attempts to ascertain whether different groups have different behavioral repertoires, which might be caused by a higher rate of social transmission within groups than between them. The chapter first considers approaches that can be applied to determine whether group differences in behavior exist, including the group contrasts approach and the method of exclusion. In particular, it discusses methods for assessing the genetic hypothesis and the ecological hypothesis. It also presents a model-fitting approach and a causal modeling framework. Finally, it highlights the limitations of studying social learning based solely on differences in repertoires.Less

This chapter considers a number of additional subjects. It first considers the determination of sanctions under a communications-based prohibition, focusing on differences that arise when employing a communications-based prohibition rather than when basing liability on the presence of successful oligopolistic coordination. The chapter then turns to an alternative rule under which liability cannot be based on circumstantial evidence, contrary to the long-standing norm in competition law. Hereafter, implications of the contrasting approaches for other areas of competition law, such as the stringency of limits on horizontal mergers and the regulation of practices that might facilitate oligopolistic coordination, are discussed. Finally, the chapter looks into the manner in which rapid evolution in communications technology might influence the analysis, particularly concerning detection.Less
