Regulators and private companies in charge of infrastructure need to share information to make sure services are efficient and costs are fair. Regulators should ask for detailed reports from companies to check if they are doing a good job and if prices are reasonable. In Chile, privatizing infrastructure helped save money, but it took a while for these savings to reach consumers because nobody was checking on the companies. By sharing information, regulators can make better decisions and prevent companies from taking advantage of the system.
