A study modeling the effects of transport infrastructure investments in Tanzania on rural income inequalities and household welfare inequalities, modeled through consumption indicators.
Generally it finds that the results of public investment measures into transport infrastructure largely depend on the financing scheme used.
Comparing four financing schemes when looking at the effects on rural households, it finds that they are generally worse off when the development is deficit-financed or paid through tariff revenues.
On the other hand, rural households benefit through increased income from measures financed through consumption taxes, or by external aid.
The general finding is that there is no pareto optimum for any of the investment measures for all locations,
and that much of the increases in welfare are based on movement of rural workers out of quasi-subsistence agriculture to other locations and other sectors.
The study creates causal inferences but is limited in its modeling approach representing a limited subset of empirical possibility spaces,
as well as having to make the assumption of no population growth for measures to hold.
