Tax(i)ing the poor? Commuting costs in South Africa

Abstract

In this paper I describe the monetary and time costs of commuting to work in South Africa. I find that these costs are high and that monetary costs of commuting have increased faster than inflation, mainly through a shift away from walking and towards minibus taxis and driving. Journey times are substantially higher than the OECD country average. Using a method suggested by Hausmann (2013) I estimate the effective tax on hourly earnings that the time and monetary costs of commuting impose. I find high effective tax rates, which are a disincentive to working far from home. This only deepens the puzzle of why South Africa's informal sector is so small, since more than half of the informally self-employed work at home and pay no transport costs. I show that whilst minibus taxis conveyed around 71% of commuters that used public transport in 2013, the industry receives less than 1% of the direct public transport subsidy provided by the South African government. I find that the subsidy accrues mainly to bus and train users in the lower middle part of the labour income distribution.
