This chapter examines two particularly testing problems affecting cross-national comparisons of advanced communication services: the increasing importance of service and price differentiation, particularly the reliance on multipart self-selection tariffs, and the challenges created by institutional diversity for making sense of comparative observations. It introduces a new metric, known as the lowest expenditure frontier (LEF), to address some of the challenges of designing good metrics, and advocates methodological pluralism to mitigate the latter. The chapter first considers the use of benchmarking to periodically assess the effects of policy and regulation on broadband before turning to a discussion of the challenges arising from the increasing heterogeneity and differentiation of advanced communication services. It then describes three approaches used to compare the prices of advanced communication services: selection of a representative price (for example, for a three-minute call) or a representative plan; reliance on an average aggregate measure, such as the average revenue per user (ARPU); and the use of a basket of calls whose cost is then calculated for different countries. Finally, it illustrates the LEF using the case of mobile voice communications.
