摘要: This paper discusses residents’ willingness to pay (WTP) for improved liquid waste treatment in Addis Ababa based on data collected 2011 using random parameter logit model. Findings indicate that respondents are willing contribute with higher quantity and quality. Their mean WTP the medium improvement scenario is found be 15.53 ETB (0.93 USD) per month. The compensation surplus tends increase from status quo alternative scenarios aggressive improvement. Finally, concludes by indicating socioeconomic difference across households, sub-cities need considered designing environmental protection plans city.
