Efficiency oOf Municipal Solid Waste Collection Systems in Ghana

For purposes of establishing a benchmark against which performance of municipal solid waste (MSW) collection systems can be evaluated by sector regulators, investors and managers, this study assessed the cost efficiency of MSW collection systems in Ghana, using stochastic frontier analysis (SFA). Data from seventy municipal solid waste collection systems were used to estimate the parameters of a Cobb-Douglas cost function. The study developed a cost function, estimated the parameters using maximum likelihood, and applied SFA to determine the efficiencies.
