The World Bank has recently conducted research on targeted subsidies in cities in Latin America. Among the main conclusions is that developing better subsidy schemes for lower income populations in the region is now possible given the use of smart cards and better methodologies for defining and identifying beneficiaries. In addition to subsidies targeted at lower income and other vulnerable groups, public transport services in the ZMVM should explore differentiated fares for peak and off-peak travel. Besides helping increase revenues, this should also help to reduce crowding at peak hours.
