Abstract

This study aimed to determine the efficiency and productivity of the production factors in the case of public transport in Sfax – the second most important agglomeration in Tunisia–. The analysis of factor productivity enabled identifying the shortcomings in the supply of this service and advocating certain strategies to boost supply. We use an estimation of the trans-logarithmic costs function with different restrictions while relying on the foundations of the microeconomic theory. We relied on annual statistical data from the Regional Transport Company in Sfax over the period preceding the COVID 19 crisis spanning from 1985 to 2018. The estimation results showed the presence of scale diseconomies, the gain in productivity over the years is too slow. The technical progress of public transport in Sfax is very low and the technical efficiency is also very limited. The results revealed that there is a decline in productivity growth due to a growing inefficiency throughout the study period.
