This innovative book combines results from research conducted in Colombia about how communications services consumers make consumption choices with OECD expertise in regulatory policy, behavioural economics, and data analytics, in order to help improve the consumer protection regime in Colombia. It focuses on the types of incentives that should be provided to change both provider and user behaviour, and considers where appropriate regulatory interventions may be needed to ensure that these incentives are realised. This work supports the Communications Regulator of Colombia in redesigning its consumer protection regime. This effort has refocused the regulatory framework from “protecting rights” towards making the market function best; this involves encouraging the providers to improve the quality of their services and rates offered in the market and to foster a better understanding of what is being offered and how. The book also makes specific recommendations on possible follow-up experiments to test some of the possible solutions to help communications services consumers better understand the information provided by service operators.
