The effects of income and fare variation on the demand for bus transit services in Brazil

The public policies on mass transit and other economic policies have been unable to avoid increasing mass transit costs and urban bus fares, which places a burden on a majority of the population depending on public transit. This study analyzes the variations in urban bus fares and households income, as well as their effects on the demand of paying commuters in 9 large Brazilian cities between 1995 and 2008. The study shows that a gap between the rise of urban bus fares and the population’s income led to a decrease of more than 30% of the paying demand between 1995 and 2003. According to the price elasticity estimated in this study, the demand for bus services has exhibited elastic behavior since 2001. Since then, the gradual increase observed in population income seems to buffer against the persistent fare increases. The recovery of the average household per capita income since then seems to support a reversal of downward trends in the number of paying passengers and an increase access to public bus services. The number of paying passengers increased about 9.5% between 2003 and 2008.The evolution of the sector's main costs complement the study, permitting an analysis of the many factors that have caused the continuous increases of bus fares in metropolitan Brazil during this period. The study concludes highlighting some public policies that could provide a better economic environment for the provision of efficient and affordable transit services.
