Abstract
Waste is a significant economic drain in developing countries, with poor waste collection services in many African cities. The government struggles to establish sustainable waste management policies to manage the waste stream in the municipality effectively. This study aims to establish a clear rationale for making waste management a priority by exploring the economic benefit of improved services of solid waste collection in the Lagos metropolis through econometrics. Using multi-stage probability sampling techniques and face-to-face questionnaire administration, the study used choice modelling to elicit households’ preferences for improved waste collection options. Data was analyzed using SPSS version 25 and Nlogit version 5.0 econometric software. Two models were run and the results revealed that all the attributes of the waste collection services were significant in models (conditional logit model basic and interactive). More so, the result of the marginal rate of substitution has indicated that FCL_3 (frequency of waste collection) is the most preferred attribute, while the least preferred is the WCA_2 (waste collection agency). The study results guide policy on residents’ willingness to pay for solid waste collection services and propose the best policy options for effective, environmentally friendly, economically viable and socially acceptable waste management in Lagos.
