AN ANALYSIS OF TECHNICAL EFFICIENCY OF PUBLIC BUS TRANSPORT COMPANIES IN MOROCCAN CITIES
AN ANALYSIS OF TECHNICAL EFFICIENCY OF PUBLIC BUS TRANSPORT COMPANIES IN MOROCCAN CITIES

Summary/Abstract: The aim of this paper is twofold. Firstly, it ‎measures the relative efficiency of six ‎public bus companies in the largest cities in Morocco for the year of 2013 and identifies, at the ‎same ‎‎‎time, potential efficiency improvements for each inefficient company.‎ Secondly, it identifies the ‎external factors that influences the measured efficiency. As a first step, the technical efficiency of the companies was measured using a ‎Constant Return to scale model of Data Envelopment Analysis method (CRS-DEA). Further, the research identifies ‎the percentage that a company needs to increase its outputs or reduce its inputs in ‎order to achieve optimal efficiency. In the second step, certain external factors ‎‎(namely those reflecting network structure, service characteristics, ‎demographic ‎and socio-economic conditions of cities) are regressed, upon the efficiency‎scores, ‎using a Tobit regression model.‎ The study results concluded that companies of Casablanca and Marrakech cities ‎are the best efficient of the sample and some exogenous factors may explain part ‎of the inefficiencies of the other companies.
