Available information on counterfeiting and piracy falls far short of what is needed for robust analysis and for policymaking. This chapter therefore focuses on what could be done to improve and expand information on counterfeiting and piracy. The chapter also suggests how measurement techniques could be advanced in order to produce more accurate global and sector-specific estimates about the magnitude, scope and effects of infringements on economies. Finally, the chapter concludes that these three areas should receive priority: 1) improving information that is available from enforcement activities (i.e. customs and related law enforcement agencies); 2) developing a framework for collecting information on the effects that counterfeit and pirated products are having on the health and safety of consumers; and 3) expanding the use of surveys to collect basic information from rights holders, consumers and governments.
